Claim 0:
1. A brake system for a vehicle, comprising:
a first-braking-force control mechanism configured to control a first braking force as a braking force to be applied to the vehicle;
a second-braking-force control mechanism configured to control a second braking force different from the first braking force, the second-braking-force control mechanism being different from the first-braking-force control mechanism;
a third-braking-force control mechanism configured to control a third braking force different from the first braking force and the second braking force, the third-braking-force control mechanism being different from the first-braking-force control mechanism and the second-braking-force control mechanism;
an abnormal-state detecting device configured to detect whether the first-braking-force control mechanism is in an abnormal state;
a controller configured to:
control the first-braking-force control mechanism so as to control the first braking force when the abnormal-state detecting device does not detect that the first-braking-force control mechanism is in the abnormal state, and
control the second-braking-force control mechanism in a stopping state of the first-braking-force control mechanism so as to control the second braking force when the abnormal-state detecting device detects that the first-braking-force control mechanism is in the abnormal state,
execute a cooperative control of the third braking force and the first braking force when the abnormal-state detecting device does not detect that the first-braking-force control mechanism is in the abnormal state, and
control the second-braking-force control mechanism in a stopping state of the first-braking-force control mechanism and the third-braking-force control mechanism so as to control the second braking force when the abnormal-state detecting device detects that the first-braking-force control mechanism is in the abnormal state; and

a pseudo-abnormal-state detecting device configured to detect whether the first-braking-force control mechanism is in a pseudo abnormal state in which the first-braking-force control mechanism is suspected to be in the abnormal state,
wherein the controller includes a pseudo abnormal state controller configured to:
control the second-braking-force control mechanism in an operating state of the first-braking-force control mechanism so as to control the second braking force when the pseudo-abnormal-state detecting device detects that the first-braking-force control mechanism is in the pseudo abnormal state, and
execute a cooperative control of the first braking force, the third braking force, and the second braking force when the pseudo-abnormal-state detecting device detects that the first-braking-force control mechanism is in the pseudo abnormal state.
