Embodiment Construction

[0018] figure 1 A perspective view is shown of an add-on module plugged onto a main module of an electronic control unit for controlling an electrically operated oil pump in a transmission.

[0019] The main module 10 includes a large number of unlabeled electronic, electrical and / or electromechanical components for controlling and / or regulating the figure 1 The internal operation of the automatic transmission of the car is not shown. The main module 10 is optionally electrically connected to an additional module 12 . All elements required for controlling or regulating the electric drive of an oil pump supplying transmission oil to the transmission are combined in the additional module 12 . In order to easily create an electrical connection between the two modules 10, 12, the main module 10 has a plug connector 14 for figure 1 The oil sump, not shown in , is sealed with a seal 16, such as an O-ring. The add-on module 12 accordingly has a double-sided coupling 18 with a fir...

Abstract

The control device (56) has a main module (52) which has a plug connector (58) for electrical connection of main module with an external wiring harness. An adaptor has main terminal electrically contacting plug connector and auxiliary terminal electrically contacting the wiring harness. An electrical coupling (60) connected to main module, includes additional electronic module (54) for driving an electric oil pump (48), main terminal (62) electrically contacted with plug connector and an auxiliary terminal (64) electrically contacted with wiring harness.

Description

technical field [0001] The invention relates to an electronic control device for an automatic transmission of an automobile. Background technique [0002] Vehicles driven by an internal combustion engine almost always require a transmission in order to compensate for the insufficient torque of the internal combustion engine in many speed ranges depending on the torque required for propulsion in the various driving situations of the vehicle. Initially, almost exclusively transmissions were used in motor vehicles in which the user could mechanically select a shift stage or gear by means of a gear lever. Purely mechanically shifted motor vehicle transmissions have been gradually supplanted in the past by automatic transmissions, such as mechano-hydraulic multi-stage automatics with torque converters, in particular for reasons of comfort. Due to the small number of shifting stages and the hydraulically operated torque converter, these early multistage automatics generally achie...
