Vehicle stability control system with tire sensor assembly
First Claim
1. A vehicle control system comprising:
- at least one tire having at least one tire characteristic that varies tire radius during vehicle operation;
a sensor assembly for measuring said tire characteristic and generating a tire characteristic signal; and
a controller for receiving said tire characteristic signal and modifying a control system output signal based on said tire characteristic.

Abstract
A vehicle control system 10 uses tire characteristic information such as tire pressure and temperature for vehicle systems such as anti-lock brake systems (ABS) 28, traction control systems 30, and stability control systems 32. Variances in tire temperature and pressure can affect the tire radius dimension, which is used to calculate vehicle speed and individual tire rotation speed. This speed data is the basic foundation for generating control output signals for ABS 28, traction 30, and stability 32 control systems. The control system includes sensors 14 for measuring tire pressure and temperature during vehicle operation to modify output control signals for the ABS 28, traction 30, and stability control 32 systems.
