Abstract

The invention provides a torque transmission method and device. The torque transmission method includes the following steps: obtaining a torque compensation parameter corresponding to engine torque from a preset storage space, calculating according to the torque compensation parameter to obtain target torque, according to the target torque, controlling a target clutch, and transmitting the enginetorque. According to the torque transmission method, the torque compensation parameter corresponding to the torque of the engine is obtained from the preset storage space, calculation is performed according to the torque compensation parameter to obtain the target torque, and finally, according to the target torque, the target clutch is controlled, and the torque of the engine is transmitted, a control strategy of a dry double clutch transmission is avoided to apply to a wet double clutch transmission, the degree of accuracy of transmission of the engine torque of the wet double clutch transmission is improved, and the safety of driving of a vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a torque transmission method and device. Background technique [0002] With the continuous development of the automobile industry, the vehicle transmits engine torque from a single-clutch transmission, and develops into a dual-clutch transmission that transmits engine torque. Also, the dual clutch transmission may include a dry dual clutch transmission and a wet dual clutch transmission. [0003] In the related art, during the process of transmitting the engine torque of the dry type dual clutch transmission, the friction causes high temperature and poor heat dissipation, and also causes serious wear and tear, so that the service life of the dry type dual clutch transmission is relatively short. Therefore, it is necessary to adjust the control strategy of the dry dual-clutch transmission according to the degree of wear, so that the dry dual-clutch transmission can effect...
