Title:
VEHICLE CONTROL METHOD AND SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/183410
Kind Code:
A1
Abstract:
A vehicle control method, comprising: obtaining an actual rotational speed and actual torque of a motor of a vehicle; calculating, on the basis of a Kalman filter rotational speed estimation model, a reference rotational speed according to the actual rotational speed and the actual torque of the motor; extracting an oscillation rotational speed according to the actual rotational speed and the reference rotational speed; determining compensation torque on the basis of the oscillation rotational speed; and implementing active damping control on the vehicle according to the compensation torque and the actual torque. Also disclosed are a control system and a vehicle. According to the vehicle control method and system, on the basis of the Kalman filter rotational speed estimation model having a parameter adaptation function, the oscillation rotational speed that can reflect a jitter characteristic of a transmission system is extracted in real time, and on the basis of the oscillation rotational speed, active damping control of the vehicle is implemented by implementing active dumping torque by a driving motor as an actuator, so that the purpose of vibration reduction is achieved.
