The invention concerns a control arrangement for an automatic electrohydraulically controlled transmission. In order to reduce expenditure on parts and assembly, the hydraulic control system and electronic control system are mounted directly adjacent each other and plug-in connections are provided between the solenoid valves of the hydraulic control system and the electronic control system. The hydraulic control system (,) substantially comprises two duct panels (,) in which control ducts, piston slides and solenoid valves (not shown) are disposed for controlling the conical plates and couplings of the transmission. The pressurized hydraulic fluid is fed directly into these duct panels from the pump (,). The electronic control system (,) has a single central connection (,) which is secured in the transmission housing cover (,) by an annular seal. Rotational speed sensors for the transmission shafts and temperature and pressure sensors are integrated into the control unit.

Control arrangement for an automatic, electrohydraulically controlled transmission

A motor vehicle control module is described comprising a control unit with a carrier body, a circuit arrangement applied on the carrier body, a housing body that at least partially encloses the carrier body, at least one stamped grid with several stamped grid connections integrated in the housing body, and also the sensors and/or actuators with sensor elements and sensor connections and respectively actuator elements and actuator connections associated to the control unit. To reduce the space requirement and the costs and to improve the susceptibility to faults in the signal transmission from the sensors/actuators to the control unit, at least some of the sensors/actuators are situated in the control unit or in the immediate proximity of the control unit and are contacted by directly joining their respective sensor connections or actuator connections with stamped grid connections of the stamped grid of the control unit.
