DESC: FIELD
The present subject matter relates to the field of mechatronics, more specifically, driving abuse prevention systems.
BACKGROUND
Typical multi-mode systems used in vehicles are required to be manually operated wherein a mode is selected by a driver based on load and road conditions. This results in abuse of the modes, higher overloading, and aggressive driving. Conventional systems addressing aforementioned drawbacks, only detect traffic violations such as over speeding, aggressive driving, tail gating and the like by the drivers. Even though the conventional systems detect the traffic violations, they are time consuming as numerous sensors are required to gain inputs. Moreover, some of the conventional systems only estimate and report behavior of the driver from a safety point of view, and do not provide automatic vehicle control based on the driver’s behavior and fuel efficiency of the vehicle.
There is, therefore, felt a need to limit the aforementioned drawbacks, and provide a system that prevents drivers from rash and negligent driving while maintaining optimal fuel efficiency.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
An object of the present disclosure is to ameliorate one or more problems of conventional driving abuse prevention systems or to at least provide a useful alternative.
Another object of the present disclosure is to provide a system that prevents drivers from rash and negligent driving.
Yet another object of the present disclosure is to provide a system that improves fuel efficiency of a vehicle.
Still another object of the present disclosure is to provide a system that controls vehicle drivability.
Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.

DETAILED DESCRIPTION
Conventional multi-mode systems used in vehicles are manually operated by drivers based on load and road conditions. This leads to problems like abuse of the modes, higher overloading, and aggressive driving. There are systems to address aforementioned drawbacks; however they only detect traffic violations such as speeding, running stop signs, aggressive driving, tail gating and the like by the drivers. Even though such systems detect the traffic violations, they are time consuming as numerous sensors are required to gain inputs. Additionally, some of the conventional systems only estimate and report behavior of the driver from a safety point of view, and do not provide automatic vehicle control based on the driver’s behavior and fuel efficiency of the vehicle. Therefore there is a need to limit the aforementioned drawbacks, and provide a system that prevents drivers from rash and negligent driving while maintaining optimal fuel efficiency.
Referring to the accompanying drawing, Figure 1 illustrates a block diagram of a system (100) for preventing drivers from rash and negligent driving in accordance with one embodiment of the present disclosure. The system (100) accepts various inputs from a vehicle and decides value of an optimum engine speed and torque limit below which the vehicle can be easily operated. This calculation can be periodically varied every time a driver of the vehicle tries to drive aggressively. The system (100) comprises a plurality of sensors. The plurality of sensors is coupled with vehicle (50). The plurality of sensors is configured to sense a plurality of parameters related to vehicle, and transmit a plurality of unprocessed signals corresponding to sensed plurality of parameters. The system (100) comprises plurality of parameters which includes speed of engine of vehicle, speed of vehicle, acceleration of vehicle, gear in position, torque of engine, and position of acceleration of pedal of vehicle.
The system (100) comprises an electronic control unit (ECU) (102) which receives plurality of unprocessed signals. The signal conditioner unit (104) is configured to receive the plurality of unprocessed signals and generate a plurality of conditioned signals corresponding to sensed plurality of parameters to obtain vehicle data. The plurality of conditioned signals is configured as an input to processing module (106). The processing module (106) is configured to store predefined set of allowable values corresponding to plurality of vehicle parameter values. The processing module (106) compares vehicle data with corresponding predefined set of allowable values and generates a plurality of control signals corresponding to compared data. The plurality of control signals is then fed to electronic control unit (102). A controller (116) is configured to cooperate with electronic control unit (102) to receive the plurality of control signals from ECU (102), and transmit plurality of control signals to ECU (102) to control plurality of vehicle parameters such as speed of vehicle engine, speed of vehicle, acceleration of vehicle, gear in operation, torque of engine and position of acceleration pedal of vehicle. The ECU (102), along with the controller (116), is adapted to the variations in the speed and torque periodically after a specified mileage interval. Multiple maps are provided by the system 100 that can be calibrated for controlling drivability under different road conditions.
The processing module (106) comprises an engine speed optimizer (108), a torque optimizer (110), a safety module (112) and an output module (114). The engine speed optimizer (108) compares actual engine speed value with predefined engine speed value, and generates control signals corresponding to engine speed. The torque optimizer (110) is configured to compare actual toque value with predefined engine torque value to generate control signal corresponding to torque signal. The system (100) comprises an advanced torque management system which monitors driver behavior, vehicle speed, gear changes (with/without grating gears), excessive acceleration and braking, and decides to increase or decrease the vehicle torque accordingly. The system (100) also estimates closely the vehicle mass based on which the road slope condition is estimated. This estimated data is further used as a fail-safe safety function in case of any wrong decision. The safety module (112) is configured to store a predefined set of instructions to provide safety instructions during an emergency situation. The output module (114) cooperating with an engine speed optimizer (108), torque optimizer (110) and safety module (112) provides an output signal to ECU (102). The safety module (112) includes a back-up option which can be used by the driver in case of failure of critical components like failure of vehicle speed sensor, malfunction in controller, or when controlling signals/inputs from the ECU (102) are not available.
In an embodiment, the system (100) includes different sensors such as an engine speed sensor, a vehicle speed sensor, as acceleration pedal displacement sensor, a vehicle torque sensor and an engine torque sensor. The system (100) further comprises an emergency override switch for manual control of vehicle during an emergency situation.
The system (100) of the present disclosure restricts aggressive driving behavior, controls drivability of vehicles both in laden and un-laden conditions, provides efficient torque management which improves life of vehicle, improves fuel efficiency, reduces fuel economy variation, provides smoother and optimized drivability within defined limits, controls maximum vehicle speed and acceleration, and provides different maps which are calibrate-able according to vehicle class and engine rating.
