Abstract
This invention discloses a method, device, storage medium, and apparatus for controlling shift torque in hybrid vehicles. Upon receiving a shift signal, the invention determines the wheel-end torque requirement based on the target gear of the target vehicle. If the target vehicle is in pure electric shift mode, the TM motor and ISG motor are controlled to interact and exchange torque based on the wheel-end torque requirement to meet the requirement. If the vehicle is in hybrid shift mode, the engine's output torque is controlled to interact and exchange torque based on the wheel-end torque requirement to meet the requirement. Because this invention uses a torque coordination control strategy during shifting to compensate for torque and meet the driver's torque needs, it effectively solves the power interruption problem during synchronizer shifting in both pure electric and hybrid shifting modes, improving the overall drivability of the vehicle's shifting process, compared to the power interruption during synchronizer shifting in existing power-split hybrid systems, which leads to a poor user experience.
