Compared with ordinary CVT (continuously variable transmission), ECVT can maintain the best transmission ratio and smooth transition in various working conditions, taking into account the economy and power of the car, and matching the transmission ratio within the optimal speed range of the engine. ECVT can realize the comprehensive control of the power transmission system, give full play to the engine performance, and make the engine always work under the best working conditions, thereby improving the combustion process of the engine and reducing exhaust emissions.
[0003] In the prior art, the application of ECVT is mainly modular, and its characteristics are that the transmission controller is separated from the actuator, and the shift actuator, clutch actuator, sensor, etc. are distributed on the transmission body in a modular manner.

In addition, EVCT has relatively high control requirements for sensor signals such as speed and displacement. The existing wiring harnesses are prone to malfunction due to vehicle bumps, which in turn causes the signal to be unable to be transmitted normally, affecting the performance and function of the transmission.
