Disclosed is a vehicle attitude control system for controlling the attitude of a vehicle in which a road wheel suspension is configured such that a roll axis of a vehicle body inclines downwardly in a forward direction. The vehicle attitude control system includes: a lateral acceleration sensor operable to detect a lateral acceleration; a brake actuator operable to apply a braking force; and a brake control device operable, based on a traveling state of the vehicle, to generate the braking force, wherein the brake control device is configured to execute vehicle attitude control of applying, to an inner rear road wheel, a larger braking force when the lateral acceleration of the vehicle is relatively large than when the lateral acceleration is relatively small, thereby suppressing uplift of an inner rear portion of the vehicle body.

A powering pattern representing velocity of a vehicle at each position of a powering interval in a braking delay period between a timing at which the vehicle exceeds allowable velocity and a braking timing at which the vehicle starts to brake, and a coasting pattern representing velocity of the vehicle at each position of a coasting interval subsequent to the powering interval in the braking delay period are calculated after calculating a braking pattern representing velocity of the vehicle in a braking interval, which is a running interval subsequent to the coasting interval and which occurs between a position of the vehicle at the braking timing and a target position for controlling the vehicle to run at predetermined velocity or less, wherein an acceleration characteristic depending on velocity of the vehicle is used to calculate at least the powering pattern.

A brake system includes an electromechanical brake having a friction surface, a lining support having a brake lining, an electric motor for moving the lining support, and a control and monitoring unit. The control and monitoring unit ascertains, from a first value ascertained during a first movement of the lining support by the electric motor, an operating parameter of at least one part of the brake, and a second value ascertained during a second movement opposite to the first movement of the lining support, by the electric motor, an operating behavior value for a real operating behavior of the relevant brake, and ascertains, by comparing the at least one real operating behavior value to at least one stored operating behavior expectation, a correction factor. The brake control system is corrected by the one correction factor and a regulator of the electric motor is activated using the corrected brake control signal.

The present disclosure relates to a braking control device that executes an anti-skid control for reducing a braking force when a difference between a target deceleration and an actual deceleration of a vehicle is greater than or equal to a reference value in a braking state in which the braking force is applied to a wheel according to an increase in the target deceleration of the vehicle, the braking control device including a control unit that executes a specific control for reducing an intervention degree of the anti-skid control as a response delay of the actual deceleration with respect to the increase in the target deceleration in the braking state becomes larger.

A method for braking a vehicle may include performing a first anti-locking brake system operation when a bump parameter of the vehicle exceeds a predetermined bump parameter threshold. A first braking force may be applied to each wheel, the first braking force being controlled such that a slip rate of each wheel lies within a predetermined first range. The method may include performing a second anti-locking brake system operation when the bump parameter is below the predetermined bump parameter threshold and when a slip rate of one or more of the wheels exceeds a predetermined slip rate threshold, including applying a second braking force to each wheel, wherein the second braking force is controlled such that the slip rate of each wheel is set so that the yaw rate of the vehicle lies within a predetermined yaw rate range.

A vehicle hill descent control system and method for controlling a vehicle during a hill descent receives inputs from an accelerator pedal position sensor and a brake pedal sensor. The method controls the engine drivetrain system to engine idling and controls the braking control system to maintain vehicle speed by increasing braking torque to minimize or offset a vehicle speed increase due to gravity. In vehicle hill descent mode, when a vehicle user actuates the accelerator pedal, the engine idling does not change. Instead, the electronic control unit operates to decrease braking torque so the vehicle speed is increased.
