Title: Method for estimating road surface friction coefficient
Inventor: KIN KEIYU
IPC: B60R16/02
Filed: 2003-06-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide an estimation method of a road surface friction coefficient for estimating an individual road surface μ for each of the left and right wheels even in a split road, where the road state differs between the left and right of the road.  <P>SOLUTION: The slip rate of each of the left and right drive wheels is calculated from the difference between a wheel speed for each of the left and right drive wheels and a body speed. The body speed that is the average value of the left and right drive wheels is differentiated and body acceleration is calculated. The body acceleration, and the slip rate for each of the left and drive wheels are set to the lateral and vertical axes, respectively, and the gradient of the slip rate to the body acceleration is obtained as slip ratio. Then, the road surface friction coefficient of each of the left and right drive wheels is estimated from the size of the gradient of the slip ratio. When the slip ratio is smaller than the first threshold, the road is determined to be a high μ road. When the slip ratio is between the first and second thresholds, the road is determined to be a middle μ road. When the slip ratio is larger than the second threshold, the road is determined to be a low μ road. Accordingly, the road surface μ can be estimated individually for each drive wheel.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
