Gear of automobile transmission of automatic type or control unit for shift program choice

摘要

A control unit for the gear or shift program selection of an automatic transmission of a motor vehicle is presented, which has a emergency release mechanism. With this a parking brake of the motor vehicle transmission can be released by an operating device that can be actuated by the driver. A housing (3) is provided and a selector lever (1), which can be brought into at least two end positions, in which control unit the operating device of the emergency release mechanism is an integral part of the control unit, and in which the operating device has a detachable stop element (7). The stop element (7) is secured in a mount (9) of the control unit by means of a coded release mechanism (15) and acts as a movement limitation for the release movement of the parking brake by the operating device of the emergency release mechanism in the non-actuated state. The emergency release mechanism can also be actuated due to this novel design even with the control unit only, and, moreover, increased requirements on theft protection can be met.
