Immobilizing device for a motor vehicle

Immobilizing device for a motor vehicle, 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 is transportable by a vehicle user;
• an actuation communication channel for immobilizer actuation communications which require authentication, between the at least one authentication element and the immobilizer control unit;
• and
• an immobilizer operating element, which is adapted to be arranged on the vehicle and is operable without any manipulation of the authentication element by the vehicle user, for user-requested initiation of an immobilizer actuation communication which requires authentication;
• wherein the immobilizer operating element comprises a multistage button element, having at least first and second button stages;
• wherein the first button stage initiates an ignition switching-on process which requires authentication, and the second button stage initiates an ignition switching-off process.

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
• wherein the immobilizer operating element comprises a multistage button element, having at least first and second button stages;
• wherein the first button stage initiates an ignition switching-on process which requires authentication, and the second button stage initiates an ignition switching-off process.
