Abstract: In a brake system including a master cylinder and an electrically-driven hydraulic pressure generator with front and rear pistons, when the hydraulic pressure generator cannot be operated and a failure of a first hydraulic system linked to a rear fluid chamber of the generator occurs and makes a first hydraulic system open to the atmosphere, the brake-fluid pressure of a second hydraulic system transmitted from the master cylinder to a wheel cylinder via a front fluid chamber of the generator is used to perform braking. A forward-facing third front cup seal provided at an intermediate portion of the front piston prevents the brake-fluid pressure generated by the master cylinder from leaking out from a front supply port via the rear fluid chamber. At the same time, a stopper prevents the pressure of the front fluid chamber from moving the front piston excessively backward. The braking is accordingly secured by use of the second hydraulic system linked to the front fluid chamber of the motor cylinder.

Abstract: A traction control method is provided for dynamically maintaining safe driving traction between a tire (12) and a driving surface in a decelerating motor vehicle (10) through a modulated braking device (18, 24). The method monitors the acceleration response of a tire (12) to a torque change induced by modulation of a braking device (18, 24). Observation of the acceleration profile over time is used to determine whether additional braking torque or pressure can be applied without causing the tire (12) to slip. A Traction Reserve value is computed through observing the acceleration trend of the tire (12) over time after a single change in torque, whether that change is accomplished as an increase or a decrease.
