Slip control mechanism of a car
First Claim
1. A slip control mechanism of a car comprising:
- hydraulic booster means for driving master cylinder means for providing hydraulic pressure to first brake means provided for each driven wheel;
second brake means provided for each driving wheel;
slip detection means for detecting slip of driving wheels;
slip control means for operating the second brake means, based on signals from the slip detecting means, by using the operating oil of the hydraulic booster means as operating oil of the second brake means so as to reduce the slip of the driving wheels, said control means comprising pressure control valve means for controlling hydraulic pressure of the operating oil of the second brake means, including pressure reducing valve means for reducing the hydraulic pressure of the operating oil of the second brake means;
detection means for detecting completion of the slip control by the operation of the second brake means; and
,release means for opening the pressure reducing valve means for a predetermined time so as to release the operating oil of the second brake means on the occasion of the completion of the slip control by the operation of the second brake means.
