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 brake system may include a first hydraulic line; a second hydraulic line; a third hydraulic line; a fourth hydraulic line; a third switch valve; a fourth switch valve; a fifth hydraulic line; a sixth hydraulic line. The brake control unit can suppress a Vapor Lock even in a frequency brake operation in the section in which the downhill traveling from the highland to the flat is continued.

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.

An avoidance modifier system may be configured to modify operation of a collision avoidance system associated with a machine. The avoidance modifier system may include at least one inclination sensor and a modifier system controller configured to be in communication with the collision avoidance system. The modifier system controller may be configured to receive an inclination signal from the inclination sensor and determine an inclination angle at which the machine is operating relative to level operation. The modifier system controller may be configured to determine an adjusted ground plane angle indicative of a virtual ground plane on which the machine is operating, and communicate with the collision avoidance system, such that the collision avoidance system does not activate a braking device of the machine in response to an object sensor generating an object signal indicative of detection of an object between an actual ground plane and the virtual ground plane.

A braking control device is provided to automatically control a main braking device normally used to brake a host vehicle during travel and a second braking device used to maintain the host vehicle in a stopped state. The braking control device has a slip degree prediction unit and a braking device switching unit. The slip degree prediction unit predicts a possibility that the host vehicle will slip. The braking device switching unit is configured to delay a timing with which to start a reduction in a braking force of the main braking device if the slip degree prediction unit predicts a slip when switching the main braking device to the second braking device.

A method and a device for determining braking-related actual values of a train assembly including multiple carriages for carrying out a deceleration-controlled braking of the train assembly, in which the longitudinal deceleration and the longitudinal slope are considered to be actual values, from which an adjustment value balancing the control deviation is determined for a control element of the brake by a deceleration controller/deceleration force controller according to a predefined setpoint value of a desired braking deceleration.
