Title:
HYBRID VEHICLE TORQUE CONTROL METHOD AND APPARATUS, STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/143305
Kind Code:
A1
Abstract:
The present disclosure relates to a hybrid vehicle torque control method and apparatus, a storage medium, and an electronic device. The method comprises: when a limitation request based on a DCT torque variation gradient is received, determining a target total torque variation gradient, wherein the target total torque variation gradient is the smaller one of the DCT torque variation gradient and a front-axle total torque request filter gradient, and determining a motor torque request and an actual torque response variation gradient of an engine; determining a torque variation gradient of a motor according to the target total torque variation gradient and the actual torque response variation gradient of the engine; and performing filtering processing on the motor torque request according to the torque variation gradient of the motor. The limitation of DCT torque gradient variation is considered, so that the problem that the actual total torque response of the motor and the engine exceeds the limitation request of the DCT torque variation gradient due to the fact that an actual response torque of the engine does not meet the limitation requirement of the torque variation gradient of the engine is effectively solved, and the drivability of the entire vehicle is improved.
