PROBLEM TO BE SOLVED: To provide an interlocked brake system capable of appropriately performing interlocked braking according to not only a load but also a traveling environment.SOLUTION: An interlocked brake system includes a first fluid pressure circuit that controls the pressure of a brake fluid to be fed to a first brake unit which brakes first wheels, a second fluid pressure circuit that controls the pressure of a brake fluid to be fed to a second brake unit which brakes second wheels, and a pump that pressurizes the brake fluid. When the first brake unit is allowed to brake the wheels, the brake fluid of the second fluid pressure circuit is pressurized by the pump in order to allow the second brake unit to brake the wheels in an interlocked manner. Herein, slip of the wheel and the brake fluid pressure are detected. If the detected slip is smaller than an ideal relationship of association, the braking force for the second wheels is increased. If the detected slip is larger than the ideal relationship of association, the braking force for the second wheels is decreased so that a current relationship of association approaches the ideal relationship of association.SELECTED DRAWING: Figure 4 |
