Description:Adaptive Lighting Control System and method thereof for vehicles
Field of the Invention
The present disclosure relates to adaptive lighting control system and method thereof. More particularly, the present disclosure relates to a system and method of controlling lighting based on the driving pattern of the driver.
Background of the Invention
A lighting Indicator system having a pair of indicators at the front and rear end of the vehicle has been known since many years. The indication system works in response to an actuating or electric switch which is pressed and slid in the direction in which the driver wants to go. There have been many times when the driver forgets to switch off the indicators and because of which blinking indicator lights create a confusion in the minds of other rear drivers on the street and also leads to unnecessary consumption of battery of the vehicle.
In order to solve the above problem, there have been attempts being made and that uses a sensor that measures rotation of handlebar and accordingly automatically switches off the indicator after the vehicle has completed its turn based on the angle of rotation. However, this solution is subjective as the rotation of handlebar will vary from driver to driver. The usual logic is to check if a turn has been executed after the rider switches on the indicator. After the rider switches on the turn indicator, the mechanism checks the handlebar turn angle or vehicle lean angle if it crosses a set threshold. Once the sensor detects a turn and returns to a straight-ahead position, the mechanism will switch-off the indicator.
Further, using an Inertial Measurement Unit (IMU) sensor to measure vehicle tilt angle is also one of the solutions, but like above, this solution is subjective.
Depending on the speed, the angle of lean and handlebar rotation required changes and may not cross the cutoffs set by mechanism. In addition, for the same turn, the values of lean and steer may be different for different riders.
Current solutions also often fail to take into account cases where riders switch on turn indicators while waiting at stop signs or red signals on the road. This also applies for cases where some riders switch on the indicator at large distances before the turn but the mechanism switches off the indicator assuming false start.
There are various other solutions that have been provided according to the existing arts, but all these solutions still have challenges because of their limited applications, inefficient functioning and interdependency on external factors. It is, therefore, important to work on the alternative solution to develop an adaptive lighting system for vehicles which learns rider behaviour and accordingly acts for shutting off the front and/or rear indicator lighting system of the vehicle. motor integrated swingarm assembly that makes the motor a component independent of the swing arm configuration and minimizes stress on the chassis or swing arms and utilizes motor as functional stress member with simplified and time saving mountings and obviates the 10 complexity and challenges of the prior arts.

Referring to figure 1, in a two-wheeler electric vehicle, rider input data from vehicle’s throttle and brake, and indicator switch are communicated to Vehicle Control Unit (VCU) for collecting information related to vehicle’s de-acceleration/acceleration, vehicle speed, RPM of engine/motor, turn indicator switch on/off, wherein an inertial measurement unit (IMU) is also provided which actually is a sensor for measuring lean angle of the vehicle.
Further, the time interval for information related to vehicle’s de-acceleration/acceleration, vehicle speed, RPM of engine/motor, turn indicator switch on/off and vehicle’s lean angle are sensed and recorded in the compute unit (intelligent processing unit) by way of communication between on-board time interval recorder and the compute unit, wherein a shut off signal corresponding to the indicator shut off is transmitted to the vehicle control unit based on computation of the data inside the compute unit.
Further, the intelligent processing unit is configured to learn rider behaviour based on collecting vehicle driving parameters such as time interval between indicator switch on and initiation of turn, between indicator switch on and changes to velocity, between indicator switch on and brake application intensity, and the IMU data to detect when the turn is completed, wherein said compute unit performs calculations and data storage on the vehicle to avoid lag issues related to transferring data to cloud based systems, wherein said compute unit creates statistical data points such as mean, median, mode, min, max and quartile range of each said vehicle driving parameters, and calculates the statistical data points of time interval between start of indicator, braking, vehicle leaning and end of leaning, and start of accelerator input, and based on the computed values of statistical data points, the compute unit decides to send a shut off signal or no change signal to the vehicle control unit.
Further, the compute unit also evaluates statistical data points of brake intensity, accelerator intensity, angle of lean of the vehicle and velocity correlation with each phase of the turn so as to provide a shut off signal more accurately at the correct time. The intelligent processing unit is provided with a storage unit which stores and contains historical data of the above statistical data points of the vehicle that has been driven for a definite time so that next time when the vehicle is turned and indicator is switched on, based on the real time statistical data points of said vehicle driving parameters, the compute unit determines shut off time employing the historical data from the storage unit and enables shut off of the indicators of the vehicle by communicating the same through the vehicle control unit.
Referring to figure 2, an architecture of a multi-level tree analytical module of the intelligent processing unit is shown, wherein each tree (T1, T2, T3, T4, T5………..Tn) represents an analysis of one or more vehicle driving parameters in terms of time interval with respect to the time at which the indicator was switched on. For Eg: For determining on/off states of the indicators, one of the trees consider speed and time in case the speed exceeds a first predetermined value (x), otherwise throttle function is considered in case the speed is below the first predetermined value (x), and further braking intensity is considered in case the throttle function exceeds third predetermined value (z). The output response of each tree is in the form of determined on/off state of the indicators, wherein the lighting indicators of the vehicle receives final output response in the form of whether the indicators is to be switched on or off, wherein a decision for switching on or off is taken based on the output response of all the multi-level trees, wherein the indicator lighting devices are automatically switched off when the output response of majority of the trees is received as switch off.
For determining on/off states of the indicators, in case when speed remain exceeded at the first predetermined value (x) for time more than the second predetermined value (y), a decision for switching off is taken based on the output response by the intelligent processing unit and in case when speed remain exceeded at the first predetermined value (x) for time less than the second predetermined value (y), a decision of keeping the switch on is taken.
Referring to Figure 3, in one exemplary embodiment, while the rider wants to turn the vehicle, and when the brake time exceeds x and lean angle exceeds 2 degrees, the indicator is kept switched on and if the lean angle is below 2 degrees, the indicator is signalled to get switched off. Further, when the brake time is less than x and during which if the throttle exceeds z, the indicator is signalled to get switched off. In case the lean angle is 0, and throttle remains below z, the indicator is kept switched on.
Further, in another exemplary embodiment, if the throttle is above its threshold value (x) for time less than y, the indicator is kept switched on, but in case, if the throttle is above its threshold value (x) for time more than y, the indicator is signalled to get switched off.
Further, in another exemplary embodiment, if the throttle is below its threshold value (x) while the braking intensity is above its threshold value (z), the indicator is signalled to get switched off, but in case if the throttle is below its threshold value (x) while the braking intensity is below its threshold value (z), the indicator is signalled to get switched on.
In accordance with another exemplary embodiment of the present invention, when the lateral acceleration (Latacc) exceeds its threshold value (x) and while the throttle remains below its threshold value (y), the indicator is kept switched on, and if throttle remains above its threshold value (y), the indicator is signalled to get switched off.
Furthermore, in accordance with another exemplary embodiment, when the lateral acceleration (Latacc) is below its threshold value (x) and while the brake intensity is above its threshold value (z) and lean angle exceeds its threshold value (p), the indicator is kept switched on, and if brake intensity is below its threshold value (z), the indicator is kept switched on.
Referring to Figure 5, shows onboard AI compute engine of the adaptive lighting control system, which includes a queuing mechanism for incoming data signals, a processing unit which accepts the queued data and uses an AI model to predict whether indicator needs to be turned off, a correction mechanism based on previous behaviour of rider, and storage to keep history of rider previous behaviour.
The data signals from Vehicle Control Unit (VCU) and Inertial Measurement Unit often arrive asynchronously and therefore it is important to have a temporary waiting space where these signals can be stored before the AI engine consumes it for calculations. The queuing mechanism provides this facility and ensures no signal is lost due to processor being busy with previous calculation, or if a data point is to be consumed in the next step while processor is busy with current step. The AI engine consumes this data and predicts whether the turn indicator needs to shut off. It can use variety of algorithms typically used for classification problem. The example of random forest is given for illustrative purpose only and not a limiting factor. Based on compute power and accuracy, a simpler algorithm such as logistic regression or a complex algorithm such as artificial neural network may also be used.
Further, the AI engine provides the first level response of whether indicator lamp should be switched off. This signal along with its related input parameters such as time since indicator lamp turned ON, lean angle, throttle, etc. are sent to the correction unit, wherein the correction unit checks in the historical storage how rider had responded when such a scenario happened in the past and accordingly updates the response. Eg. if for similar events in past with same parameter values, if the rider immediately switched ON the indicator after algorithm shut it OFF, then the correction unit will update the output to keep the indicator lamp ON. Similarly in case the first response is to keep the indicator ON but historical behaviour shows rider switched off the lamp, then updated response will be to switch off the lamp. This ensures each rider gets a custom trained response suitable for his/her riding pattern. The storage unit is a fast access device so decision making is not obstructed, wherein its size can be tuned to have memory of few days to a few months.
