Patent ID: 12005880

Abstract:
A vehicle brake system, including: a first hydraulic-pressure control mechanism and a second hydraulic-pressure control mechanism configured to control a braking force; and a controller including a first-abnormal-state detecting device configured to detect whether the first hydraulic-pressure control mechanism is in a first abnormal state, a second-abnormal-state detecting device configured to detect whether the first hydraulic-pressure control mechanism is in a second abnormal state that the first hydraulic-pressure control mechanism reaches before reaching the first abnormal state, and an assist control device configured to control the second braking-force control mechanism so as to control the braking force when an assist wait time elapses after the second-abnormal-state detecting device has detected that the first hydraulic-pressure control mechanism is in the second abnormal state, the assist wait time being determined based on a temperature of a working fluid obtained by a temperature obtaining device of the brake system.
