First Claim
Patent Images
1. A yaw rate estimation system for a vehicle, said yaw rate estimation system comprising:
- a control receiving inputs indicative of (i) a first yaw rate determined by a yaw rate sensor of the vehicle, (ii) a second yaw rate derived from wheel sensors of the vehicle, (iii) a third yaw rate derived from a lateral acceleration of the vehicle and (iv) a fourth yaw rate derived from a steering wheel angle, wheel angle and rate of change of steering wheel angle; and
wherein said control is operable to process said inputs to estimate the actual yaw rate of the vehicle, wherein the estimated actual yaw rate is derived from said inputs.

Abstract
A yaw rate estimation system for a vehicle includes a control receiving inputs indicative of (i) a first yaw rate determined by a yaw rate sensor of the vehicle, (ii) a second yaw rate derived from ABS wheel sensors of the vehicle, (iii) a third yaw rate derived from a lateral acceleration of the vehicle and (iv) a fourth yaw rate derived from a steering wheel angle, wheel angle and rate of change of steering wheel angle. The control is operable to process the inputs to estimate the yaw rate of the vehicle, with the estimated yaw rate derived from the inputs.

18. A yaw rate estimation system for a vehicle, said yaw rate estimation system comprising:
-
a control receiving inputs indicative of (i) a first yaw rate determined by a yaw rate sensor of the vehicle, (ii) a second yaw rate derived from wheel sensors of the vehicle, (iii) a third yaw rate derived from a lateral acceleration of the vehicle and (iv) a fourth yaw rate derived from a steering wheel angle, wheel angle and rate of change of steering wheel angle; wherein said control receives at least some of said inputs via a communication bus of the vehicle; wherein said control is operable to process said inputs to estimate the actual yaw rate of the vehicle, wherein the estimated actual yaw rate is derived from said inputs; and wherein said control is operable to estimate the actual yaw rate of the vehicle using statistical estimation and analysis of said inputs indicative of said first, second, third and fourth yaw rates. - View Dependent Claims (19, 20)
