Hybrid vehicle, control method and control system thereof and storage medium

Abstract

The invention discloses a control method and a control system of a hybrid vehicle, the vehicle and a medium. The method comprises the steps of detecting an accelerator pedal treading action, and outputting an acceleration signal; in response to the acceleration signal, controlling an engine to increase the rotating speed, and controlling a motor to output the whole vehicle required torque to the wheel end; when detecting that the rotating speed of the engine reaches the rotating speed of the clutch input shaft corresponding to the target gear, controlling the clutch corresponding to the targetgear to be combined; distributing engine target torque according to the whole vehicle operating parameters and the whole vehicle required torque, and controlling engine output torque according to theengine target torque; and adjusting the motor output torque according to the engine output torque, so that the wheel end outputs the whole vehicle required torque. According to the control method ofthe hybrid vehicle, the rotating speed and the output torque of the engine can be controlled under the refueling working condition of the vehicle, the target gear clutch is combined, and the vehicle pause phenomenon caused by inconsistency of the rotating speed of the engine and the rotating speed of the target gear input shaft is avoided.

Description

technical field [0001] The present invention relates to the technical field of vehicle manufacturing, in particular to a control method of a hybrid vehicle, a control system of the hybrid vehicle, the hybrid vehicle, and a computer-readable storage medium. Background technique [0002] For a hybrid vehicle, for example, a hybrid vehicle with a dual clutch automatic transmission (Dual Clutch Transmission, DCT), it is driven by an engine and an electric motor. [0003] In some related technologies, when the hybrid vehicle is in a coasting or braking condition, the clutch torque corresponding to the current gear is engaged less or not, so that the engine speed is lower than the input shaft speed corresponding to the current gear. Under working conditions, the motor and the engine output torque. Since the engine speed is lower than the shaft speed corresponding to the current gear, the engine output torque is all used to increase the engine speed when the engine starts to output...

Problems solved by technology

[0003] In some related technologies, when the hybrid vehicle is in a coasting or braking condition, the clutch torque corresponding to the current gear is engaged less or not, so that the engine speed is lower than the input shaft speed corresponding to the current gear. Under working conditions, the motor and the engine output torque. Since the engine speed is lower than the shaft speed corresponding to the current gear, the engine output torque is all used to increase the engine speed when the engine starts to output torque. The output torque of the wheel end is only the output torque of the motor. , the engine speed rises rapidly. When the engine speed rises rapidly and exceeds the shaft speed corresponding to the current gear, the clutch is quickly engaged, and the transmitted torque is greater than the engine torque, so that the torque output to the wheel ends is greater than the torque required by the vehicle, causing the vehicle to stumble.
