Embodiment Construction

[0041] figure 1 The unit of the device 1 is shown with a receptacle 2 for an electronic key 3 and an integrated start / stop switch 4 . The receptacle 2 has a spring-loaded flap 5 which closes the receptacle 2 when no key 3 is inserted, so that the ingress of dirt or moisture is prevented. By inserting the key 3, the valve cover 5 is opened in the direction opposite to the spring force.

[0042] When the key 3 is inserted and after the electronic key 3 has been successfully authenticated, the engine can be started by actuating the start / stop button 4 and stopped by actuating the button 4 again.

[0043] In order to authenticate the key 3 it comprises a sending and receiving unit exchanging one or more codes with the control unit. The device 1 can be integrated anywhere inside the vehicle, preferably in the dashboard.

[0044] figure 2 A cross-sectional view of the device 1 is shown schematically, wherein only the locking mechanism is shown in the locked position. The elect...

Abstract

The invention relates to a mechanism (1) for starting a vehicle engine by means of an electronic key (3). Said mechanism (1) comprises a receiving device (2) in the vehicle for inserting the key (3). The key (3) that is inserted in said receiving device (2) cannot be twisted while being movable in a longitudinal direction into at least one defined raised position. Such mechanisms are provided with locking devices which secure the electronic key (3) in the receiving slot against being removed during operation of the vehicle. Said locking device is controlled via electrical drives (10). In order to be able to remove the key (3) when the drive (10) is down or in case of a power failure in the vehicle, means are that provided that allow the key (3) to be removed mechanically as an emergency measure.

Description

technical field [0001] The invention relates to a device for starting the engine of a vehicle by means of an electronic key, comprising a receptacle (Aufnahme) in the vehicle for inserting the key, when inserted into said receptacle the key cannot be turned but can be moved along Longitudinal movement to at least one defined lifting position (Hublage), the lifting position of the key is monitored by a plurality of sensors of a control unit and used to control various functions of the engine, and when the key is in a specific lifting position, The key cannot be removed from the receptacle by means of a locking element controlled by an electric drive. The invention also relates to an electronic key for such a receiving device. Background technique [0002] A device of this type is known from DE 199 39 733 A1, wherein the electronic key is prevented from being removed by a mechanism in the device and the associated magnetic coil (Hubmagnet). [0003] In this blocking position...
