Title: Road face condition judging apparatus
Inventor: IWASAKI KATSUHIKO
IPC: B60T8/1763
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To correctly judge a road face condition with being hardly affected by disturbances such a noises, etc., and reduce costs with utilization of an existing wheel velocity sensor, by executing judgment from an analysis result of frequencies of wheel velocity signals. SOLUTION: Wheel velocity signals detected by a wheel velocity sensor 10 are supplied to an electric control device (ECU) 12. Measured wheel velocity data are supplied to a fast Fourier transformer(FFT) 14 and subjected to Fourier transform. A gain at each frequency is calculated, whereby a frequency spectrum of a wheel velocity is obtained. On a wet road with a wet face, the gain at a predetermined frequency (e.g. 30 Hz) or lower is large as a whole. On a dry road with a dry face, the gain at the predetermined frequency or lower is small. A road face condition, i.e., whether a road face where a vehicle is running is wet road or dry road can be judged from a sum of gains at the predetermined frequency or lower of the frequency spectrum of the wheel velocity. The ECU 12 executes brake control accordingly.
