摘要： Disclosed are a hybrid vehicle torque adjusting method and device. The method includes: acquiring a requested torque of a front-axle engine and a requested torque of a rear-axle motor, determining a first compensation torque according to the filtered requested torque of the front-axle engine and an actual output torque of a front-axle transmission, and determining a target torque of the rear-axle motor according to the first compensation torque and the requested torque of the rear-axle motor. In the method, since a difference exists between the filtered requested torque of the front-axle engine and the actual output torque of the front-axle transmission during shifting of the front-axle transmission, after the difference is compensated by the rear-axle motor, a working condition that affects a dynamic performance of an entire vehicle can be eliminated, torques can be coordinated, and the dynamic performance of the entire vehicle can be improved.
