The invention provides a torque slow rise control method and equipment, a storage medium and a device, and the method comprises the steps: obtaining a current vehicle speed, a current vehicle acceleration and a current torque value of a vehicle torque, and inputting the current vehicle speed and the current vehicle acceleration into a preset starting condition judgment model, and when the model judgment result meets the preset condition, obtaining the current motor rotating speed and the current accelerator opening degree of the vehicle, then determining a termination torque value, and controlling the torque of the vehicle to be increased to the termination torque value from the current torque value in an exponential incremental mode. Compared with the mode of eliminating the impact torqueby adding additional parts in the prior art, the method has the advantages that the current condition is judged through the preset starting condition judgment model, and the termination torque valueis determined when the model judgment result meets the condition; and the vehicle torque is controlled to rise from the current torque value to the final torque value in an exponential incremental mode, and torque impact is eliminated.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a torque ramp control method, equipment, storage medium and device. Background technique [0002] During the driving of electric vehicles, the target torque control is generally performed by the vehicle controller VCU. The control of the output target torque by the VCU needs to comprehensively consider the pedal opening signal and the motor speed signal. The inverter adjusts the output of different target torque signals under DC, and the waveform of the electric-to-AC current is output by the drive motor. The response speed of the drive motor to the target torque is very fast, and the response time is generally in the order of milliseconds. Therefore, the change rate of the drive motor torque to time is large, which will cause a torque impact on the transmission parts (such as gears) and the soft connection parts of the car (such as the cab support cushion), which will affec...
