PROBLEM TO BE SOLVED: To provide a regenerative and cooperative brake system that can demonstrate stroke operation force (tread force) characteristics of a superior brake pedal with a simple structure.SOLUTION: An operation force input to a brake pedal 5 is not transmitted to a master cylinder 7, until the position of the brake pedal 5 exceed an invalid stroke range from an initial position by function of a machine type stroke simulator 10. At this point, an elastic force of a coil spring 32F is given to the brake pedal 5 as a reaction force to the operation. The operation force input to the brake pedal 5 is transmitted to the master cylinder 7 when the position of the brake pedal 5 exceeds the invalid stroke range. At this time, the elastic force of the coil spring 32F given to the brake pedal 5 is constant, and the reaction force provided from master cylinder 7 for brake pedal 5 increases as the operation amount of brake pedal 5 increases. |
