IPC: B60T8/58
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To accurately predict the maximum road surface frictional coefficient without being affected by a variation in a road surface state and without providing excessive vibration to a vehicle. SOLUTION: Based on a brake oil pressure signal Pb in time series from a pressure sensor 16 and a wheel speed signal ωw in time series from a wheel speed sensor 22, a braking force gradient predicting part 23 obtains an origin braking force gradient α0, an instantaneous braking force gradient α, and a braking force F at that time. The maximum braking force predicting part 24 calculates the maximum braking force Fmax by using the origin braking force gradient α0, instantaneous braking force gradient α, and braking force F at that time. A μmax predicting part 25 obtains the maximum road surface frictional coefficient μmax by substituting the maximum braking force Fmax obtained in the maximum braking force predicting part 24 and a wheel load W.
