Electronics Module

Mechatronics Of The Automatic Transmission
The mechatronics of the 6HPTU automatic transmission consists essentially of the electronic module and the hydraulic module.

Electronic module
The electronic module is divided mainly into the following components:
- EGS control module
- Power supply for solenoid valves and electronic pressure control valves
- Transmission sensor system:
- Sensor for the transmission input speed
- Sensor for the transmission output speed
- Transmission oil temperature sensor
- Transmission connector for connection to vehicle wiring harness

EGS control module
In the 6HPTU transmission, the EGS is fitted as part of the transmission. It evaluates the sensors electronically and directly activates the actuators of the hydraulic module. A temperature sensor of the EGS processor additionally monitors the transmission oil temperature.

Hydraulic module
The hydraulic module is similar to the modules used so far in transmissions. It is designed as holder for the electronic module.
