DESC:TITLE OF THE INVENTION
A SYSTEM AND METHOD FOR INDICATING A DRIVING PATTERN OF A BATTERY POWERED VEHICLE

FIELD OF THE INVENTION
[0001] The present disclosure relates, generally, to a battery power vehicle, and more particularly relates to a system and method for displaying an indication of driving behavior of a battery powered vehicle during a travel of the vehicle.
BACKGROUND OF THE INVENTION
[0002] Electric vehicles, generally, include an electric power storage unit for powering the vehicles. With the growing use of the electric vehicles, it becomes necessary to provide an information about a distance that the electric vehicles may cover at the start of a journey. The current system, generally, determine and display a range of distance coverable by the electric vehicles based on an average efficiency and an amount of energy stored in the electric power storage unit. Generally, the average efficiency is determined either based on an ideal driving scenario, including, constant speed and proper road infrastructure, or the cumulative energy consumed by the vehicle over the cumulative distance covered by the electric vehicle. However, during a travel of the electric vehicle, the actual efficiency may differ from the average efficiency due to a change in road conditions, a change in a loading of the electric vehicle, a change in driving behavior of the driver of the vehicle, for example, rapid acceleration, idling, rapid and frequent braking, etc., or a combination thereof. In light of this, during the travel of the vehicle, a distance actually coverable/covered by the electric vehicle may differ from the predicted range of distance determined at the start of the vehicle, which is undesirable. Hence, there is a need to inform the driver about an inefficient operation/driving of the electric vehicle and suggest improvements in an operation of the electric vehicle to the user by evaluating the driving behavior of the driver of the electric vehicle.

[0021] FIG. 1 shows an exemplary battery powered vehicle 100 (hereinafter referred to as vehicle 100) in the form a scooter. While a scooter is shown, any other appropriate type of electric vehicle, such as, but not limited to, a motorcycle, a car, a truck, or any other electric vehicle that is powered by a battery for propelling over a road may also be contemplated. The vehicle 100 may include a frame 104 supporting a vehicle body 106, a pair of wheels 108 supporting the frame 100 over the road. Further, the vehicle 100 further includes a power storage unit 110, such as, a battery, for providing power for propelling the vehicle 100 over the road and auxiliary systems of the vehicle 100. Although the battery is contemplated as the power storage unit 110, it may be appreciated that a capacitor, a supercapacitor or any other suitable power storage unit 110 suitable for storing an electric power can also be utilized. Further, the vehicle 100 may include an electric motor 112, a transmission 114, and a braking system 116. The vehicle is driven/propelled by a drivetrain including the power storage unit 110, the electric motor 112 connected to the power storage unit 110 to convert the electric power received from the power storage unit 110 to a rotational kinetic energy and operatively connected to the transmission 114, that in turn is operatively connected to the one or more wheels 108. The transmission 114 transfers power received from the electric motor 112 to the wheels 108 to rotate the wheels 108 and propel the vehicle 100 over the road. The transmission 114 may be any automatic transmission or a manual transmission to achieve a plurality of forward and reverse drive gears having corresponding gear ratios to provide a range of speed and torque outputs necessary for the vehicle 100 to travel over the road.
[0022] FIG. 2 shows a schematic illustration of the drivetrain 120 of the vehicle 100 from the power storage unit 110 to the wheels 108. The electric motor 112 may include a motor output shaft 122, while the transmission 114 includes a transmission input shaft 126 at an input end and a transmission output shaft 128 at an output end. The forward and reverse drive gears of the transmission 114 have corresponding gear ratios for transmitting the input speed and torque at the transmission input shaft 126 as a desired output speed and torque at the transmission output shaft 128. The transmission output shaft 128 may in turn be operatively connected to and propels the wheels 108. Further, the drivetrain 120 may include a clutch 130 to selectively disengage the motor output shaft 122 from the transmission input shaft 126. The clutch 130 facilitates a disengagement of the motor output shaft 122 from the transmission input shaft 126 in response a pressing or a displacement of a clutch lever 132 (shown in FIG. 1) from a free position.
[0023] Referring again to FIG. 1, the braking system 116 may include a brake lever 136, a brake lever position sensor 138, and one or more brake devices 140 (shown in FIG. 2). The brake devices 140 are operatively connected to the wheels 108. The brake devices 140 are selectively actuatable in response to displacement of the brake lever by the operator to apply a braking/retarding force to slow the wheels 108 and correspondingly a ground speed of the vehicle 100. In some implementations, the brake devices 140 are operatively connected to the brake lever 136 by a mechanical linkage or a cable so that displacement of the brake lever 136 is converted into a corresponding movement of the brake devices 140. Moreover, the vehicle may include a plurality of driver input devices for inputting commands for the electric motor 112, the transmission 114, the braking system 116, the clutch 130, and other systems of the vehicle 100. The operator input devices may include an accelerator 142 (shown in FIG. 1) for controlling a speed of the motor output shaft 122, the brake lever 136, the clutch lever 132, one or more gear shift levers and the like.
[0024] Referring to FIG. 3, a schematic illustration of a system 150 for indicating a driving behavior/pattern to the driver of the vehicle 100 is shown. The system 100 includes a sensing unit 152 for detecting at least one operating parameters of the vehicle 100 during a travel of the vehicle 100. For so doing, the sensing unit 152 may include a variety of sensors operating independently or as components of other control and monitoring systems to automatically monitor various operational data/parameters during travel of the vehicle 100. For example, the sensing unit 152 has a plurality of sensors associated with the operator input devices to detect manipulation of the operator input devices by a driver/operator/user of the vehicle. In an exemplary embodiment, the sensing unit 152 may include the brake lever position sensor 138 operatively connected to the brake lever 136 to detect a displacement of the brake lever 136 from a free position of the brake lever 136. Similarly, the sensing unit 152 may include a clutch lever position sensor 154 and an accelerator position sensor 156 operatively connected to the clutch lever 132 and the accelerator 142, respectively, to detect a displacement of the clutch lever 132 and the accelerator 142. In some embodiments, the sensing unit 152 may include a gear sensor 158 to detect an operating gear of the vehicle 100. In an exemplary embodiment, the sensing unit 152 may include temperature sensor (not shown in the figure) to determine temperature of various components like motor, brake, clutch, and other various internal components.
[0025] The sensing unit 152 also collects and records other operational data or parameters relating to the operation of the vehicle 100 as it travels over the surface. The sensors monitoring the operational data may include speed sensors detecting vehicle, electric motor and transmission speeds, and torque sensors sensing torque at various points along the drivetrain and/or rolling resistance of the wheels 108. In an embodiment, the sensing unit 152 may include an motor output speed sensor 160 for monitoring/detecting a rotational speed of the motor output shaft 122, a transmission input speed sensor 162 for monitoring/detecting a rotational speed of the transmission input shaft 126, and a transmission output speed sensor 164 for monitoring/detecting a rotational speed of the transmission output shaft 128. Also, the sensing unit 152 may include a steering handle position sensor 166 for monitoring/detecting a turning of a steering handle 168 from its default position. In an embodiment, the sensing unit 152 may also include a load sensor 170 for detecting a payload of the vehicle 100. In some implementation, the sensing unit 152 may include a current sensor 172 to determine/detect/measure a current drawn by the electric motor 112 from the power storage unit 110.
[0026] The system 150 also includes a controller 174 such as an electronic control module (ECM) to receive information from various sensors and components of the vehicle 100 and control various subsystems, components of the vehicle 100. The controller 174 is operatively connected to the power storage unit 110, the sensing unit 152, the electric motor 112, and other systems of the vehicle 100. The controller 174 may be capable of processing the information received from the sensing unit 152, and outputting command and control signals to the electric motor 112, the transmission 114, the braking system 116, and various actuators of the vehicle 100. In an embodiment, the controller 174 may be in communication with a display device 200 to display one or more operating parameters of the vehicle 100 along with an indication of a driving behavior/pattern of the driver of the vehicle. As shown in FIG. 4, the display device 200 of the system 150 is adapted to indicate/show a data related to operation of the vehicle. For example, the display device 200 may indicate/display/show a speed of the vehicle 100, a nominal efficiency of the vehicle 100, an expected range of distance coverable by the vehicle 100, etc. In an embodiment, the display device 200 may include a first display area 210 to display the indication of the driving behavior/pattern, and a second display area 220 for indicating/displaying the expected range of distance coverable by the vehicle 100 based on inputs from the controller 174.
[0027] The controller 174 may include a processor 176 for executing specified instructions, which controls and monitors various functions associated with vehicle 100. The processor 176 may be operatively connected to a memory 178 for storing instructions related to the control of the vehicle 100 and vehicle components. In an embodiment, the memory 178 may also store various driving events performed/occurred during the travel of the vehicle 100. The processor 176 is adapted to determine the driving behavior/pattern based on one or more driving events.
[0028] The memory 178 as illustrated is integrated into the controller 174, but those skilled in the art will understand that the memory 178 may be separate from the controller 174 but onboard the vehicle 100, and/or remote from the controller 174 and the vehicle 100, while still being associated with and accessible by the controller 174 to store information in and retrieve information from the memory 178 as necessary during the operation of vehicle 100. Although the processor 176 is shown, it is also possible and contemplated to use other electronic components such as a microcontroller, an application specific integrated circuit (ASIC) chip, or any other integrated circuit device. Moreover, the controller 174 may refer collectively to multiple control and processing devices across which the functionality of the drive control system and other systems of the vehicle 100 may be distributed. For example, the electric motor 112, the drivetrain 120, the braking system 116, and the display device 200 may each have one or more controllers that communicate with the controller 174.
[0029] The sensors corresponding to the operator input devices sense or detect input actions by the operator and are operatively connected to the controller 174 to transmit sensor signals having values corresponding to the input of the operator. The sensors transmit sensor signals to the controller 174 in response to the operator manipulating the operator input devices. The sensor signals may be used by the controller 174 to control the corresponding components or systems of the vehicle 100, such as the electric motor 112, the transmission 114, the brake devices 140, or to perform further processing related to the operation and control of other components. In an embodiment, the controller 174 may process the sensor signals to determine one or more operating parameters of the vehicle 100, and may process the operating parameters to determine a driving behavior or pattern of the driver of the vehicle 100. The operating parameters may include, but not limited to, a depression of the brake lever 136, an operating gear of the vehicle 100, a ground speed of the vehicle 100, a speed of the electric motor 112, the payload of the vehicle 100, a position of the clutch lever 132, a position or a movement of the steering handle 168, a movement or a position of the accelerator 142, a current drawn by the electric motor 112, etc.
[0030] The controller 174 is adapted to determine the driving pattern of the vehicle 100 for each predetermined duration or each predetermined distance of travel based on the value of operating parameters detected by the sensing unit 152 during the corresponding predetermined time duration or predetermined distance of travel. In an embodiment, controller 174 may determine a start of the electric motor 112 by a user and initiate a counter upon the start of the electric motor 112, and may keep increasing the counter till either the predetermined time duration has elapsed or the vehicle 100 has travelled the predetermined distance. The controller 174 is adapted to reset the counter after either the elapse of the predetermined time duration or the coverage of the predetermined distance by the vehicle 100. In some implementations, the controller 174 is configured to determine a plurality of driving events based on the data or information about the operating parameters received from the sensing unit 152. Such driving events may include frequent braking, fast accelerating, accelerating when reaching a turn, accelerating while driving in a turn, braking while driving in a turn, sudden braking, accelerating while exiting turn, braking while exiting turn, frequent engagement/disengagement of clutch, excess payload, etc.
[0031] For example, the controller 174 may ascertain a total number of de-pression of the brake lever 136 during the predetermined duration or the predetermined distance of travel based on the input from the brake lever position sensor 138. The controller 174 may determine the frequent braking when the total number depression of the brake lever 136 is above a threshold value. Also, the controller 174 may also determine if the vehicle 100 is travelling at an optimum gear based on an input from the accelerator position sensor 156 and an input from the gear sensor 158. Also, the controller 174 may also determine fast acceleration based on a speed of a movement of the accelerator 142 from a free position and/or a rate of increase of speed of the electric motor 112 based on inputs from accelerator position sensor 156 and the motor output speed sensor 160. Also, the controller 174 may determine the braking while driving in a turn based on the inputs received from the steering handle position sensor 166 and the brake lever position sensor 138. In an embodiment, the controller 174 may determine an excess loading if the payload detected by the load sensor 170 is above a threshold value. Also, the controller 174 may determine an electric current drawn by the electric motor 112 corresponding to a speed of the motor output shaft 122 based on the inputs from current sensor 172 and the motor output speed sensor 160. Accordingly, the controller 174 may determine a driving pattern of the driver of the vehicle 100 by determining/detecting various driving events. In an embodiment, the controller 174 may store the data and information related to each driving event in the memory 178 for future access. In an implementation, the controller 174 may store the information of each driving event with a time stamp.
[0032] In an embodiment, the controller 174 is configured to determine the driving pattern of the driver of the vehicle 100 for each predetermined duration of travel of the vehicle 100 or for each predetermined distance of travel of the vehicle 100. In an embodiment, the predetermined duration may be 10 seconds. Although, predetermined duration of travel is contemplated as 10 seconds, it may be appreciated that any value of the predetermined duration of travel can be utilized. In some implementations, the predetermined distance may be 100 meters. Although, predetermined distance of travel is contemplated as 100 meters, it may be appreciated that any value of the predetermined distance of travel can be utilized. Moreover, the controller 174 is adapted to output a command to the display device 200 to display a visual indication indicating a driving/pattern to the driver of the vehicle 100.
[0033] The controller 174 is adapted to communicate with the display device 200 and actuates the display device 200 to indicate the driving pattern/behavior for each predetermined duration or predetermined distance of travel after the elapse of the corresponding predetermine duration or the corresponding predetermined distance of travel. For so doing, the controller 174 may control/actuate the first display area 210 of the display device 200 and display a color in first display area 210 corresponding to the driving pattern/behavior. For example, the first display area 210 may show/display a green color if the driving pattern/behavior confirms to a desired driving pattern/behavior, while the first display area 210 may show/display a red color if the driving pattern/behavior deviates from the desired driving pattern/behavior indicating a decrease in a real-time efficiency of the vehicle. Further, in some implementations, an intensity of the color displayed by the first display area 210 may vary/changes if the value of deviation increases. For example, the intensity of the red color is less if the determined driving pattern/behavior deviates from the desired driving pattern/behavior by a smaller value, while the intensity of red color may increase when the value of the deviation is large. In an embodiment, the first display area 210 may display a shape or a symbol to indicate the driving pattern/behavior of the driver of the vehicle 100.
[0034] In an embodiment, the driving pattern/driving behavior confirms to the desired driving pattern/behavior if there are no driving events during the predetermined duration of travel or predetermined distance of travel. In some implementations, the driving pattern/behavior confirms to the desired driving pattern/behavior if a number of driving events detected during the predetermined duration of travel or predetermined distance of travel is below a threshold value. In an embodiment, the threshold value may depend on a mode of driving of the vehicle. For example, a threshold value for a normal mode of driving of the vehicle may be less than a threshold value for a sport mode of driving of the vehicle 100.
[0035] In an embodiment of the invention, the controller 174 may determine the driving pattern of the driver of the vehicle on the fly or dynamically. In this situation there is no predetermined time or distance based on which the controller determines the driving pattern. Further, the controller 174 may decide to dynamically change the timing or distance after which the driving pattern of the vehicle may be determined. For. example in case the driver has been driving good for past predetermined time frames, then the controller 174 may increase the timing and distance after which the driving pattern may be determined. This decision may be taken by the controller 174 as for the last few times of the predetermined time determination or predetermined distance determination the driving pattern was good hence, there is no need to utilize the determination with a same frequency. In same manner a decrease in predetermined time and distance may be performed to check bad driving pattern.
[0036] Further, the controller 174 may determine a data related to a nominal efficiency of the vehicle 100. In an embodiment, a value of the nominal efficiency is stored in the memory 178. In an embodiment, a value of the nominal efficiency may be an efficiency of the vehicle 100 determined by a manufacturer of the vehicle 100 and stored in the memory 178. In some other implementations, the controller 174 may determine/calculate the cumulative distance travelled by the vehicle 100 and the cumulative energy discharged by the power storage unit 110 for facilitating the travel of the vehicle 100 for the cumulative distance, and determine the nominal efficiency based on the cumulative distance and the cumulative energy discharged by the vehicle 100. The controller 174 may determine the nominal efficiency at the start of the electric motor 112, and hence, at the start of the travel of the vehicle 100, and may keep the nominal efficiency constant during the journey of the vehicle 100. Further, based on the nominal efficiency and the energy stored in the power storage unit 110, the controller 174 may calculate/determine an expected range of distance coverable by the vehicle 100. The controller 174 may determine the expected range when the electric motor 112 is started. In some implementations, the controller 174 may take into account a state of health of the power storage unit 110, an ambient temperature, etc., for calculating/determining the expected range of the vehicle 100. In some embodiments, the controller 174 may detect/determine the mode of driving of the vehicle 100 and calculates/determines the nominal efficiency and/or the expected range by considering the mode of the driving of the vehicle 100. In some implementations, the controller 174 may also consider the payload of the vehicle 100 to determine the nominal efficiency and/or the expected range of the vehicle 100. Upon calculation/determination of the expected range, the controller 174 may output a command to the display device 200 to display the expected range of distance. In an embodiment, the display device 200 may actuate the second display area 220 to display an expected range of distance that the vehicle can travel. In an embodiment, the second display area 220 displays the expected range of distance in numerical numbers.
[0037] In this manner, the system 150, and hence, the vehicle 100, is adapted to show the expected range of distance coverable by the vehicle 100 and a driving pattern/behavior to the driver of the vehicle 100 during the travel of the vehicle 100. The driving pattern/behavior may indicate the driver that the driver is driving the vehicle 100 in an un-efficient manner and thereby provide a real-time feedback to the driver and may induce the driver to change the driving behavior. Also, the system 150 provides a feedback to the driver that the vehicle may be unable to achieve the expected range based on the visual indication displayed or shown in the first display area 210, and hence indicates to the driver that the real-time efficiency of the vehicle 100 is low.
