Immobilizing device for a motor vehicle
First Claim
1. Immobilizing device for a motor vehicle having a brake pedal, comprising:
- an immobilizer control unit, which is mountable on a vehicle, and which allows driving operation of a vehicle only if an access authorization check is positive;
at least one authentication element which can be carried by a vehicle user; and
an actuation communication channel for immobilizer actuation communications which require authentication, between the at least one authentication element and the immobilizer control unit;
wherein the immobilizer control unit enables and activates engine starting in response to operation of the brake pedal when an authentication signal communicated from the authentication element is present; and
further comprising an immobilizer operating element including a button element arranged on a transmission selection lever of the vehicle.

Abstract
An immobilizing device for a motor vehicle includes an immobilizer control unit on the vehicle, one or more authentication elements which can be carried by the user, and an actuation communication channel for immobilizer actuation communications which require authentication, between the authentication element and the immobilizer control unit. The immobilizer control unit allows driving operation and/or engine starting only if the driving authorization check is positive. According to the invention, an immobilizer operating element arranged on the vehicle can be operated without any manipulation of an authentication element, for user-requested initiation of the immobilizer actuation communication processes which require authentication. Alternatively or additionally, the brake pedal can be used as an operating element for activating engine starting, once it has been enabled by the immobilizer control unit.
