A hydraulic brake system, including: a brake operation member; a brake device; a master cylinder; a communication switching valve; a low-pressure-source shut-off valve; a high-pressure source; a regulator; a pressure adjuster; and a controller, wherein, when a pressurizing state of the master cylinder is switched from a first pressurizing state to a second pressurizing state after initiation of an operation on the brake operation member, the controller executes a pressurizing-state switching control in which switching of a state of the low-pressure-source shut-off valve from an open state to a closed state and switching of a state of the communication switching valve from a closed state to an open state are carried out after a pressure-regulating state of the regulator has been switched from a first pressure-regulating state to a second pressure-regulating state by controlling the pressure adjuster to increase a second pilot pressure while the first pressurizing state is maintained.

A vehicle control apparatus is provided with: a controller (i) configured to set first brake fluid pressure associated with wheels on one of left and right sides out of a plurality of wheels to be higher than second brake fluid pressure associated with wheels on the other side in order to turn a vehicle in one direction, and configured (ii) to then increase the second brake fluid pressure by using a fluid pressure difference between the first brake fluid pressure and the second brake fluid pressure, and (iii) to set the first brake fluid pressure to be lower than the second brake fluid pressure while holding the second brake fluid pressure in order to turn the vehicle in another direction, which is different from the one direction.

A soft-park control system to control vehicle movement during parking of a vehicle includes a transmission and one or more brake assemblies. The transmission includes a parking pawl that mechanically engages a notch in a parking gear. The brake assembly includes an electro-mechanical actuator configured to apply a variable brake force to a wheel coupled to a brake assembly based on an existing brake pressure. The soft-park control system further includes an electronic control unit having a soft-park hardware controller in electrical communication with the electro-mechanical actuator. The electronic brake control unit outputs a brake pressure signal that adjusts the existing brake pressure so as to control a rate at which the parking pawl engages the notch.

A vehicle behavior control device is for use in a vehicle including a brake pedal, a master cylinder generating a hydraulic pressure in response to an operation with the brake pedal, an electric hydraulic pressure generator connected to the master cylinder and electrically generating a hydraulic pressure based on the operation with the brake pedal, and a wheel cylinder in each wheel for braking. The device controls a brake hydraulic pressure to be applied to the wheel cylinder to control vehicle behavior. When brake control is executed such that a brake hydraulic pressure not based on the operation with the brake pedal is generated if the brake pedal is not being operated, a hydraulic pressure applied to a wheel cylinder in a diagonal wheel positioned diagonal from a brake wheel for controlling the behavior of the vehicle is adjusted to the hydraulic pressure in the master cylinder.

The device that generates the friction braking force to decelerate the vehicle estimates the disturbance torque acting on the vehicle. When the accelerator operation amount is equal to or less than the predetermined value and the vehicle is just before the stop of the vehicle, the control device for vehicle causes the friction braking amount to converge to the friction braking amount to the value decided on the basis of the disturbance torque estimated value Td in conjunction with the reduction in the motor rotation speed (speed parameter) proportionate to the traveling speed of the vehicle.

A method and device for determining a target curve incline of a motor vehicle during traveling of a curved roadway section is disclosed. A momentary transverse acceleration of the motor vehicle is determined depending on a momentary speed of the motor vehicle and a momentary roadway curvature of the curved roadway section determined by an optical detection system. A momentary target curve incline for the motor vehicle is calculated from the determined momentary transverse acceleration. A modified momentary target curve incline is calculated by weighting of the calculated target curve incline with a speed-dependent target curve incline weighting factor. The momentary roadway curvature is determined by additionally using a vehicle navigation system of the motor vehicle.
