The vehicle braking control device adapted to a vehicle brake device having an electromagnetic valve which controls the brake fluid flow between the master cylinder and the wheel cylinders in response to the input electric energy. The vehicle braking control device includes a valve opening electric energy obtaining portion which obtains an input electric energy upon opening of the electromagnetic valve as a valve opening electric energy and an operation characteristic setting portion which sets an operation characteristic based on the valve opening electric energy obtained corresponding to the predetermined pressure differential. The opening valve electric energy obtaining portion changes the input electric energy at a valve closing side or a valve opening side with a change amount per unit of time larger than before valve opening in response to an obtaining of the valve opening electric energy.

Vehicle braking control device

Vehicle brake device comprises a master cylinder including a master chamber connected to a wheel cylinder, a drive pressure chamber in which a drive pressure is generated for driving a master piston and a fluid pressure chamber in which a fluid pressure is generated in response to a stroke position of the master piston and an operating characteristics setting device for setting operating characteristics of an electromagnetic valve. The operating characteristics include a relationship of the pressure differential in the fluid conduit between the master cylinder side and the wheel cylinder side with respect to the electromagnetic valve based on the supply amount of the electric power detected by the supplied electric power detecting device.

Vehicle brake device

A motion control device for a vehicle includes a vehicle speed obtaining device, a curvature obtaining device for obtaining a bending grade of a curve existing ahead of the vehicle, a position obtaining device for obtaining a relative position between the vehicle and the curve, a determination device for determining an appropriate vehicle speed for the vehicle passing through the curve based on the bending grade, a speed reduction control device for executing a speed reduction control for reducing the vehicle speed based on the vehicle speed and the relative position so that the vehicle passes through the curve at the appropriate vehicle speed, and a gradient obtaining device for obtain a gradient of the road on the curve existing in a traveling direction of the vehicle, wherein the determination device determines the appropriate vehicle speed based on the gradient of the road in addition to the bending grade.
