Abstract

The present application discloses an accelerator pedal torque recognition method and device. When the HCU detects the driver's touch operation on the central control screen, it acquires the touch information of the touch operation; then, acquires the actual position of the accelerator pedal; Then, according to the acquired touch information and the actual position of the accelerator pedal, the driver's demand torque is calculated and distributed to the engine and the motor as the target torque, and the slope limit interval of the calculated torque rise is sent to the engine and the motor, so that the engine And the motor outputs corresponding target torque according to the driver's demand torque and the slope limit interval of torque rise. It can be seen that the application realizes the output of the corresponding torque according to the driver's wishes, thereby solving the problem of calculating the vehicle's output torque and its response speed to the accelerator pedal only by relying on the HCU to analyze the hard-wired signal, and the driver cannot independently adjust the accelerator pedal. The technical problems of fast response speed and response sensitivity have improved the driver's driving experience.

Description

technical field [0001] The present application relates to the technical field of hybrid electric vehicle control, in particular to a method and device for identifying accelerator pedal torque. Background technique [0002] With the rapid development of the economy and the improvement of environmental protection awareness, the utilization rate of hybrid electric vehicles is also increasing, and the identification and output of accelerator pedal torque is also a key technology for the development of hybrid electric vehicles. [0003] The current recognition method for the accelerator pedal torque is to connect the accelerator pedal sensor to the vehicle controller (Hybrid Control Unit, HCU for short) through a hard wire, and then the HCU can analyze the accelerator pedal position from the hard wire signal, and then convert the calculation into driving The torque demand of the driver, and through filtering, torque intervention, etc., the torque is distributed as a torque reques...
