Vehicle control system utilizing gps data
First Claim
1. A vehicle control system for controlling a performance characteristic of the vehicle comprising:
- a controller coupled to the vehicle control system, the controller adapted to receive a vehicle position signal, the controller employing the position signal to determine at least one characteristic pertinent to the operation of the vehicle control system and outputting a control signal, and further adapted to receive a weather signal;
wherein said weather signal affects said determination of said characteristic, said weather signal received through broadcast radio transmission;
wherein the vehicle control system receives the control signal and tailors its performance in response thereto; and
wherein the controller is operable in a default mode wherein the controller outputs a predetermined default control signal.

Abstract
A vehicle having a vehicle control system for controlling a performance characteristic of the vehicle and a controller. The controller is coupled to the vehicle control system and adapted to receive a position signal indicative of the present physical position of the vehicle. The controller employs the position signal to determine at least one characteristic pertinent to the operation of the vehicle control system and outputs a control signal. The control signal is received by the vehicle control system, causing the vehicle control system to tailor its performance in response thereto. A method for controlling a vehicle having a vehicle control system is also provided.

11. A vehicle control system for controlling a vehicle comprising:
-
an anti-lock brake system for controlling a brake force exerted by a brake caliper to limit vehicle skidding in a predetermined manner;
a traction control system for controlling acceleration of the vehicle to limit wheel slip in a predetermined manner;
a stability system for controlling a yaw rate of the vehicle in a predetermined manner;
a database of various roads, including data on road surface type;
a controller coupled to the anti-lock brake system, the traction control system and the stability system, the controller adapted to receive a vehicle position signal and a weather signal indicative of a proximate weather condition, and to produce a control signal in response thereto, the controller operable in a default mode wherein the controller outputs a predetermined default control signal, the controller determining the road surface type associated with the vehicle position and further determining a road surface condition based on the road surface type and the proximate weather conditions the control signal indicative of the road surface type and the road surface condition; and
;
wherein the anti-lock brake system, the traction control system and the stability system receive the control signal and tailor their performance n response thereto. - View Dependent Claims (12, 17, 21)

13. A method for controlling a vehicle having a vehicle control system, the method comprising the steps of:
-
providing a controller for receiving a vehicle position signal;
providing a database of various roads, including data on road surface type;
determining the road surface type corresponding to the vehicle position signal;
inputting a weather signal indicative of a proximate weather condition;
determining a road surface condition based on the road surface type and the proximate weather condition;
generating a control signal based the road surface condition, including determining a if a predetermined condition exists, generating the control signal if the predetermined condition does not exist, and otherwise operation in a default mode; and
enhancing the performance of the vehicle control system based on the control signal. - View Dependent Claims (14, 15, 18, 19, 20)
