Abstract

The invention discloses a vehicle torque control method and device and a computer readable storage medium, and the method comprises the steps: determining the current maximum available power and the current maximum available current of a motor of a vehicle according to the current maximum discharging capacity of a battery when the vehicle runs; according to the current maximum available power of the motor and the vehicle speed of the vehicle, determining the current maximum torque of the motor; determining the current compensation torque of the motor according to the current maximum available current of the motor and the actual current of the motor; and determining the current maximum torque which can be provided by the motor according to the current maximum torque and the current compensation torque of the motor. According to the scheme, battery energy can be output to the maximum extent, and battery over-discharge caused by motor driving is avoided.

Description

technical field [0001] The present application relates to the technical field of vehicle safety, in particular to a vehicle torque control method and device, and a computer-readable storage medium. Background technique [0002] Electric vehicles are environmentally friendly and non-polluting, and have strong acceleration performance and driving NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance, thanks to the use of electric energy from the power battery to drive the vehicle through the motor. drive. When the motor drives the vehicle, it will consume battery power. The battery outputs high voltage and high current to meet the driver's demand for strong power for the vehicle. The larger the output current, the greater the torque provided by the motor, but the high output current has an impact on the cycle life of the battery. . The cycle life of the battery is closely related to the current of the battery when it is working. Over-current driving o...
