The electrical control system / for automatic transmission provides extremely precise control of the moments of gear shifting and torque converter lock-up, depending on the driving conditions of the vehicle and engine / engine operation. In addition, the use of an electric control system can significantly improve the quality of gear shifting.
The electrical part of the automatic transmission control system consists of three parts:
A) Sensors that determine the parameters of the state of the car, and transmit this data to the electronic control unit.
b) A control unit that detects shift points and controls the torque converter lock-up clutch.
V) The executive part, which consists of solenoid valves.
