Automotive vehicle with automatic gear box equipped with a control logic for the shift-lock function and the key-lock function

摘要

The motor vehicle has an electromagnetic release (2) that allows the gear selector lever (1) to be released from the park position active for a set time, for example a minute, before a brief press on the brake pedal is sufficient to release the selector lever. The control is provided by a logic circuit, which in addition to the brake press release function which cancels the shift-lock of the gear selector lever, provides a lock to prevent withdrawal of the ignition key from the ignition if the gear selector lever is not in a given position. Sensors fitted to the selector lever give a position indication. A manual release is provided if one of the sensors fails.
