Title:
VEHICLE TORQUE PROCESSING METHOD AND DEVICE, VEHICLE CONTROLLER AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/207405
Kind Code:
A1
Abstract:
A vehicle torque processing method and device, a vehicle controller and a vehicle, the method comprising: distributing torque to a first power drive system and a second power drive system according to required torque, the sum of a first torque outputted by the first power drive system and a second torque outputted by the second power drive system being equal to the required torque; and if the characteristic frequency of the first power drive system at the current vehicle speed is a frequency in a resonance frequency interval corresponding to the first power drive system, modifying, according to the required torque and the peak torque of the second power drive system, the torque outputted by the first power drive system and the second power drive system. The described method may reduce the torque distribution for the first power drive system to the greatest extent while satisfying the required torque, thereby significantly reducing the vibration and noise of the first power drive system that experiences resonance, and thus ensuring the smoothness of a vehicle.
