The present invention provides a vehicle control device that can reduce the delay in the deceleration response of a vehicle to a deceleration command. The present invention modifies the distribution ratio of brake fluid pressure between front brakes and rear brakes on the basis of lateral motion information, vehicle information, and a collision risk or a traveling scene obtained from information pertaining to the external surroundings. The brake fluid pressure is distributed to only one of the front brakes or the rear brakes.

Brake system of a motor vehicle having front wheels and rear wheels having a hydraulic service brake device. The system further includes an electrically actuatable pressure-providing device, wherein the pressure-providing device is connected to the first and second wheel brakes, comprising a parking brake device having electric-motor-actuatable wheel brakes at the rear wheels, and an electronic open-loop and closed-loop control unit, wherein in a hydraulic fallback operating mode of the brake system, in the case of a brake pedal actuation by a vehicle driver, only the first wheel brakes are connected to the master brake cylinder and supplied with pressure by the driver by the master brake cylinder, while the rear wheels are braked by the electric-motor-actuatable wheel brakes.

A damping force control device 10 comprises vary damping shock absorbers, a detector, and a controller. Each of the shock absorbers sets damping coefficient from a minimum value to a maximum value in order to adjust damping force. The detector detects vertical vibration state quantity relating to vibration of the sprung mass. The controller performs an ordinary control for setting the damping coefficient based on the vertical vibration state quantity and according to a predetermined control law suitable for an assumption that all of the wheels touch ground. The controller performs, when at least one of the wheels is an ungrounded wheel which does not touch the ground and each of the other wheels is a grounded wheel which touches the ground, a specific control for setting the damping coefficient of the shock absorber corresponding to the grounded wheel to a first specific value greater than the minimum value.

A hydraulic brake distributor for a two-wheeled vehicle has an outer body that forms an internal cavity accommodating two floating piston valve elements. The two floating piston valve elements are axially movable and mutually coupled in a telescopic manner. One of the two floating piston valve elements has an internal through-channel.

A steering control system for a commercial vehicle having a braking system to brake dissymetrically side wheels. The steering control system, including a sensor unit and a control module, is configured to detect a braking request or deceleration of the vehicle and/or to detect a lateral offset and to generate a brake indication signal and/or steering demand. The control module is configured to receive the brake indication signal and/or steering demand. If the steering demand is below a predetermined threshold value, the control module is configured to generate the steering signal only if the brake indication signal indicates a braking request. If the steering demand exceeds the predetermined threshold value, the control module is configured to generate the steering signal even if the brake indication signal indicates no braking request. The control module provides the steering signal to the braking system to brake the vehicle dissymetrically to steer the vehicle.
