Under Pressure Compensation for Wheel Radius Based on Wheel Speed

Abstract:

Tire under-pressure will increase vehicle’s rolling resistance, additional fuel consumption and possibility of tire wear, which will magnify the possibility of a flat tire when vehicle drives at a high speed. In addition, an under-pressure tire will cause a smaller wheel radius, which influences wheel speed calculation in Anti-lock Braking System (ABS) and reduces the control robustness. In this paper, an under pressure compensation algorithm for wheel radius based on ABS wheel speed is proposed, which can improve the accuracy of ABS control and indirectly give early warning of a single under-pressure tire as well. Finally it has been validated by vehicle experiments.
