Problems solved by technology
In the development of future cars, more emphasis will be placed on the coordination between the car and the driver, especially to enhance the adaptability of the vehicle to different driving styles, that is, to accurately and quickly identify the driver's style, and use the corresponding control strategy to balance the performance of the car. Fuel efficiency and the driver's power demand, thereby limiting the variation of the engine's power demand

The invention relates to a driver style identification data collection system, comprising a microcontroller, a power module, a signal input module, a signal output module and a communication module. The signal input module comprises a signal conditioning circuit connected with the microcontroller, a pedal position signal collection circuit connected with the signal conditioning circuit, a rotationspeed signal collection circuit connected with the signal conditioning circuit, and a torque signal collection circuit connected with the signal conditioning circuit. The signal output module is usedfor outputting a control signal to a vehicle. The communication module is used for communicating with an upper computer and transmitting a pedal position signal collected by the pedal position signalcollection circuit to the upper computer. The upper computer is used for extracting driver style features and feeding back the features to the microcontroller. The microcontroller realizes vehicle control through utilization of the signal output module. According to the system, a driver style can be identified; and each circuit module is integrated, so a whole control unit is integrated, and whole circuit wiring is also simplified.
Description
technical field [0001] The invention relates to a driver style recognition data collection system. Background technique [0002] Driving style is a habitual operation mode of the driver, which mainly refers to the driver's control of the speed, acceleration, brake pedal and driving distance according to the external driving environment when driving the car. Different drivers have different driving styles, and the same driver's driving style is not fixed. We usually divide driving styles into two categories: steady and aggressive. Different styles of drivers have different requirements for the pedal position range. Aggressive drivers often have higher requirements for vehicle power, so they have greater requirements for the pedal position range, and the engine generally operates in a high fuel consumption area. Especially for hybrid electric vehicles, the instantaneous high power peak request leads to frequent start and stop of the engine, which increases the fuel consumpti...
