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 smart brake system for safety at movement on a slope, includes: a multi-brake which comprises a deceleration brake for working while moving on a descending slope and a ratchet brake for working while moving on an ascending slope; a brake controller which selectively controls one of the deceleration brake and the ratchet brake to work as buoyancy of fluid is varied depending on the movement on the descending or the ascending slope.

A machine includes an engine, a brake system, a speed sensor, a grade sensor, a load sensor, and a controller in electrical communication with the engine, the brake system, the one or more retarding systems, the speed sensor, the grade sensor, and the load sensor. The controller is configured to: determine a grade force based on the weight of the machine and the grade at which the machine is disposed; determine a deceleration force based on a target deceleration and the weight of the machine; monitor the speed at which the machine is traveling; determine an actual deceleration of the machine based on the monitored speed at which the machine is traveling; determine a deceleration error based on a difference between the actual deceleration and the target deceleration; determine a force correction based on the deceleration error; and control the brake system to apply a total brake force equal to the sum of the grade force, the deceleration force, and the force correction.

A stability control system of a vehicle utilizing an electronic control unit that detects a yaw condition while each of the wheel brakes are actuated by EBCM and the wheel speeds are zero. An electronic control unit includes an electronic braking control module that controls actuation and de-actuation of vehicle brakes on an inclined surface. A yaw condition is identified while all vehicle brakes are actuated on the inclined surface and each wheel speed is zero. The electronic control unit identifies which uphill wheel is leading a direction of the yaw and identifies a wheel of an opposing axle diagonal to the identified uphill wheel. The electronic control unit in cooperation with the electronic braking control module de-actuates the vehicle brakes of the identified uphill wheel and diagonal wheel to increase a side friction to the identified diagonal wheels to reduce further yawing of the vehicle.

A computer includes a processor and a memory storing instructions executable by the processor to determine at least one of a vehicle pitch or a longitudinal center of gravity from data measured while deactivating a first brake for a first axle and applying a second brake for a second axle, and operate the vehicle based on the at least one of vehicle pitch or longitudinal center of gravity. The instructions may further include to determine a vehicle weight from the data, and operate the vehicle based on the vehicle weight.

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.
