New energy automobile accelerator pedal torque calculation method and system and readable storage medium

Abstract

The invention discloses a new energy automobile accelerator pedal torque calculation method and system and a readable storage medium. The calculation method comprises the following steps: obtaining the opening degree of an accelerator pedal; obtaining the maximum torque from the power system at different vehicle speeds to the wheel edge when the opening degree of the accelerator pedal is 100%, and obtaining the maximum torque from the power system at different vehicle speeds to the wheel edge when the opening degree of the accelerator pedal is 0%; and according to the maximum torque from the power system of different vehicle speeds to the wheel edge when the accelerator pedal opening degree is 100% and the maximum torque from the power system of different vehicle speeds to the wheel edge when the accelerator pedal opening degree is 0%, obtaining the torque from the power system to the wheel side at different accelerator pedal opening degrees and different vehicle speeds between 0% and 100%. According to the new energy automobile accelerator pedal torque calculation method, the sliding energy recovery torque is fused into the accelerator pedal torque, the defect that a conventional torque recognition method is poor in responsiveness is overcome, the response continuity of the accelerator pedal torque is improved, the driving intention is better recognized, and the driving quality of an automobile is improved.

Description

technical field [0001] The invention relates to the technical field of automobile accelerator pedal torque calculation, in particular to a new energy automobile accelerator pedal torque calculation method, system and readable storage medium. Background technique [0002] Accelerator pedal torque directly affects the driving performance of the vehicle. The current conventional method is to simply superimpose the driving torque of the power system (engine, drive motor), and superimpose the engine torque and drive motor torque under different accelerator pedal openings to obtain different accelerator pedal openings. lower powertrain torque. [0003] However, since both hybrid electric vehicles and pure electric vehicles have the function of energy recovery, the conventional method does not integrate the energy recovery torque into the accelerator pedal torque, which will lead to discontinuity of the accelerator pedal torque, especially in the process of switching between accele...
