Steering and braking stability program
First Claim
1. A vehicle comprising:
- a steering mechanism having an input member and an output member, the input member operable for receiving a steering input, the output member moveable in response to the steering input, the output member being positionable to control the direction in which the vehicle travels;
an input device adapted to produce a steering signal indicative of a manual steering input received from a vehicle operator;
a vehicle control system for controlling a performance characteristic of the vehicle by receiving the steering signal and tailoring its operation in response thereto;
whereby the vehicle control system monitors the steering signal and determines a steering angle offset such that the vehicle control system repositions the output member to reduce wheel slip.

Abstract
A vehicle having a steering mechanism and a vehicle control system which cooperate to improve the performance of the vehicle and the vehicle control system. The vehicle also includes an input device adapted to produce a steering signal indicative of a manual steering input received from a vehicle operator. The steering mechanism has an input member operable for receiving a steering input and output member moveable in response to the steering input. The output member is positionable to control the direction in which the vehicle travels. The vehicle control system is operable for controlling a performance characteristic of the vehicle, and may include an anti-lock brake system, a traction control system or a stability system. The vehicle control system receives the steering signal and tailors its operation in response thereto. Preferably, the vehicle control system includes a control unit for selectively calculating a steering angle offset which is operable for causing the steering mechanism to reposition the vehicle wheels to further improve the performance of the vehicle control system and the vehicle. A method for controlling a vehicle is also provided.

8. A method for controlling a vehicle comprising the steps of:
-
providing a vehicle control system for controlling a performance characteristic of the vehicle;
producing a steering signal indicative of a manual steering input received from a vehicle operator;
determining if a vehicle wheel slip characteristic will exceed a predetermined maximum wheel slip based at least partially on the steering signal;
calculating a steering angle offset; and
repositioning an output member in accordance with the steering angle offset such that wheel slip is reduced. - View Dependent Claims (9)
repositioning the output member in accordance with the steering angle offset to counteract vehicle yaw.
