Abstract
A brake system includes an accumulator accumulating hydraulic oil discharged from a hydraulic pump, a hydraulic oil cooler cooling the hydraulic oil discharged from the hydraulic pump, a switch valve switching between a first oil channel that allows supplying the hydraulic oil from the hydraulic pump to the accumulator but not to the hydraulic oil cooler, and a second oil channel that allows supplying the hydraulic oil from the hydraulic pump to the hydraulic oil cooler, and a controller controlling an engine to increase an engine speed of the engine when a first detector detects timing to switch the switch valve from the second oil channel to the first oil channel and a second detector detects that the engine is running at idle.
