Kind Code:
A
Abstract:
To provide a braking control device of a vehicle with brake-by-wire constitution that can maintain functions of itself even if some part thereof operates disorderly.SOLUTION: A braking control device comprises: an electric motor having a main coil and a sub coil; a fluid pump which is driven by the electric motor to discharge braking fluid to a pressure regulating fluid path; a main pressure regulator valve which is provided in the pressure regulating fluid path and regulates the braking fluid discharged by the fluid pump to regulated fluid pressure Pa; a sub pressure regulator valve which is provided in the pressure regulating fluid path and regulates the braking fluid discharged by the fluid pump to auxiliary fluid pressure Pb; and a controller which has "a main control part which supplies electric power to the main coil to control the main pressure regulator valve" and "a sub control part which supplies electric power to the sub controller to control the sub pressure regulator valve". The regulated fluid pressure Pa is transmitted to wheel cylinders through a first path, and the auxiliary fluid pressure Pb is transmitted to the wheel cylinders through a second path different from the first path.SELECTED DRAWING: Figure 1
