Abstract

A control system for vehicle devices uses an access control device to specify an identification datum, which is used by a control module to modify operation of a set of vehicle devices and functions of such devices. The control module can either disable access to the set of devices or modify operations of the vehicle devices by limiting the functionality of the selected vehicle devices. A valet using a valet key can drive the car under restrictions and a selected set of vehicle devices can be disabled during a valet'"'"'s use of the vehicle.

Claims

1. A vehicle based access control system for controlling access to at least one vehicle telematics device, the system comprising:

first and second ignition keys respectively having a first and a second identification datum specifying first and second access rights of a key user, wherein one of said first and second ignition keys comprises a valet key including an embedded transmitter having a unique identity;

a receiver port associated with an ignition switch of the vehicle for reading an identification datum on a key inserted into the ignition switch; and

a control module coupled to the receiver port and to the at least one vehicle telematics device for recognizing the identification datum received from the receiver port and modifying a predetermined set of operating features of the at least one vehicle telematics device based on an access right specified by the identification datum the control module further operative to disable the at least one vehicle telematics device upon recognizing the unique identity of the valet key.

2. The vehicle based access control system of claim 1, wherein said at least one vehicle telematics device comprises at least one of communication devices, vehicle databases, navigation systems, audio systems, vehicle personalization systems, video systems, preferences stored in an electronic memory, and voice command controls.

3. The vehicle based access control system of claim 1, further comprising:

an electronic bus for coupling said receiver port to said control module.

4. The vehicle based access control system of claim 3 wherein said control module comprises:

a key signal processing circuit connected to said receiver port and operative to receive identification datum loaded by said receiver port from an inserted key, said key signal processing circuit identifying said inserted key and generating an operating features modification signal based on said identification datum; and

a control circuit coupled to said electronic bus, said control circuit modifying operating features of the at least one vehicle telematics device upon receiving said operating features modification signal.

5. The vehicle based access control system of claim 1 wherein said control module modifies operation of the at least one vehicle telematics device to control at least one vehicle operation parameter.

6. The vehicle based access control system of claim 5 wherein said vehicle operation parameter comprises at least one of distance traveled, fuel consumed, speed of the vehicle, vehicle location as determined by a global positioning system (GPS), and climate control inside the vehicle.

7. The vehicle based access control system of claim 1 wherein the control module, upon recognition of a predetermined one of the first and second identification data, enables the key user to customize at least one of the first and second access rights.
