Pure electric power assembly control method, device and equipment and storage medium

Abstract

The invention discloses a pure electric power assembly control method, device and equipment and a storage medium. The method comprises steps that a torque demand value of a current vehicle is obtained, and a current output torque is determined according to the torque demand value; vehicle driving data and a preset danger limit value of the current vehicle are obtained, and when the vehicle driving data are not larger than the preset danger limit value, the current vehicle is driven according to the current output torque; when the vehicle driving data is larger than the preset danger limit value, the torque demand value is adjusted, the final output torque is determined according to the adjusted torque demand value, and the current vehicle is driven according to the final output torque; by means of the method, the pure electric power assembly can be transited to the safe state when errors occur, uncontrollable torque caused by function failure is prevented, the situation that the whole vehicle is in dangerous states such as unexpected acceleration, unexpected deceleration and unexpected movement is avoided, and comprehensive optimization of the dynamic property, economical efficiency and comfort of the whole vehicle is achieved.

Description

Technical field [0001] The present invention relates to the field of vehicle electronics, and more particularly to a pure electric power assembly control method, apparatus, device, and storage medium. Background technique [0002] Since the vehicle's electronically controlled system has a relatively high complexity, the risk of failure of the system and hardware and software is also increasing; once the failure occurs, it is not only endangered with the safety of vehicle driving passengers and pedestrians, but also causes vehicle production due to vehicle recalls, compensation. Enterprises are facing huge risks of profit and goodwill losses. [0003] The existing solution is to process whether the motor is required to process or perform the processing of the cutting torque by monitoring the actual torque of the motor, or performs processing of the cutting torque, or is required by the torque control value and the failure monitoring. However, the defect is that there is no specifi...
