PURPOSE:To early find out re-skid immediately after re-adhesion by a method wherein current speed data are inputted to a storage part and a skid control part, an average acceleration determined on the basis of the speed data stored till the previous time is inputted to the skid control part, and when wheels are restored to re-adhesion from skid, all the speed data are replaced by the maximum speed in the speed data. CONSTITUTION:Speed data V1 are determined by an arithmetic part 2 on the basis of a speed pulse obtained from the current speed of a vehicle and inputted to a speed pulse input part 1 and are inputted to a speed data storage part 3 and a skid control part 5. The speed data storage part 3 outputs speed data V2 to Vn obtained till the previous time, and an average acceleration computing part 4 computes an average acceleration alphabeta and inputs it to the skid control part 5. When it is detected that wheels are restored to re-adhesion from skid, all the speed data in the storage part 3 at this time are rewritten by the maximum speed Vmax determined by an arithmetic part 6. According to this constitution, re-skid immediately after the re-adhesion is found out early, braking is quickened and damages of the wheels and rails are prevented. |
