Abstract:
1. A brake control device, comprising: a plurality of wheel cylinders in which each wheel cylinder is provided to each of a plurality of wheels respectively and receives a fluid pressure of fluid and provides a braking force to each wheel, a depression force fluid pressure circuit which transmits the fluid pressure of fluid pressurized by pedal force input into a brake pedal to a plurality of wheel cylinders, a power fluid pressure generator to pressurize fluid regardless of an operation of the brake pedal, a fluid pressure control circuit which regulates fluid pressure of fluid pressurized by the power fluid pressure generator and transmits fluid pressure to a plurality of wheel cylinders, a stroke simulator which generates an anti-power depending on an operation quantity of the brake pedal operation and permits the brake pedal operation, an electronic control device which executes a normal control mode for generating a braking force depending on the brake pedal operation quantity using the fluid pressure control circuit while operating the stroke simulator and a depression force fluid pressure mode for generating a braking force using the depression force fluid pressure circuit while stopping the stroke simulator selectively, a rapid startup means for starting the electronic control device by the brake pedal operation when a vehicle ignition is off, further comprising a rapid startup mode switching control means for switching a braking mode from the depression force fluid pressure mode to the normal control mode in a middle of a returning operation of the brake pedal when the electronic control device starts by the rapid startup means.
