What is an automatic transmission control system

The control system of the automatic transmission uses the planetary gear mechanism to change the speed. It can change the speed automatically according to the degree of the accelerator pedal and the change of the vehicle speed. The driver only needs to control the speed of the vehicle with the accelerator pedal.

The gearbox is one of the most important parts of the car, which can change the car rotation ratio, expand the drive wheel rotation and speed. The transmission is composed of a variable speed transmission mechanism and an operating mechanism. The transmission can be divided into a manual transmission and an automatic transmission. When the rotation direction of the engine is kept unchanged through the gearbox, the car can still run backwards, and the power transmission of the car can be reduced when the car is in neutral, and the engine can start to change gears. The continuous development of science and technology has changed the transmission from the manual transmission in the past to the current stepless transmission, which makes the fuel consumption of the engine lower when the power is higher.
