Electric vehicle motor torque control method, storage medium and electronic equipment

Abstract

The invention provides an electric vehicle motor torque control method, a storage medium and electronic equipment. The control method comprises the following steps: responding to a torque switching control signal, determining a target torque according to a driving state signal of an electric vehicle, determining the torque change amount according to the target torque and the current torque, obtaining the torque adjustment time and the corresponding relation between the torque change rate and the time according to the driving state and the torque change amount, and therefore obtaining the corresponding relation between the motor torque and the time, and controlling the motor torque according to the corresponding relation between the motor torque and the time. According to the scheme, the specific position of the torque zero point is not concerned, calculation amount is greatly reduced, due to the fact that the corresponding relation between the motor torque and the time in the whole process from the current torque to the target torque is directly obtained through the scheme and used for controlling motor torque output, overall planning is conducted in the motor control process, andcompared with the scheme of only paying attention to zero-point torque change control, the better anti-shaking effect is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent control of electric vehicles, in particular to a method for controlling torque of electric vehicle motors, a storage medium and electronic equipment. Background technique [0002] In electric vehicles, the magnitude of the motor torque is determined by the motor controller of the electric vehicle drive system, and the output torque of the motor acts on the reducer, which drives the wheels to rotate. In some scenarios, such as the driver performing a gear shift operation or an electric vehicle transitioning from energy recovery to normal driving, there are situations where the motor output torque needs to change between positive and negative values ​​in a short period of time. In this case, the gears of the reducer need to perform forward and reverse switching actions, and the gear clearance will cause tooth grinding, which will cause car impact noise and car vibration, which will affect the ri...
