In a method for controlling a hydraulic brake system in a vehicle, wherein the hydraulic brake system is equipped with a hydraulic pump, the hydraulic pump is activated to hold the vehicle at rest and brake fluid is conveyed via open inlet valves to the wheel braking device of a first vehicle axle. The inlet valves on wheel braking devices of a second vehicle axle are at least partially open in response to a change in the brake pressure requirement in the brake system, and at the same time the outlet valves on said wheel braking devices remain closed while the vehicle is being held at rest.

Provided are an apparatus and a method for parking control of a vehicle and the method includes a step in which a control unit determines a driver's parking intention by receiving a brake signal, pressure of a master cylinder, and a position of a shift lever from a brake switch, a pressure detection unit, and a shift lever detection unit, respectively; a step in which the control unit determines a state of the vehicle by receiving an inclination, a wheel speed, and a vehicle speed from an inclination detection unit, a wheel speed detection unit, and a vehicle speed detection unit, respectively; a step in which the control unit determines a state of an electronic parking brake; and a step in which the control unit operates the electronic parking brake through an EPB driving unit.

The assembly comprises a body wherein there are defined a chamber, a supply valve adapted to connect the chamber to a pressure source or to the atmosphere, and a vent valve adapted to allow or prevent the connection of the chamber to the atmosphere. The valves are provided with control solenoids to which respective electronic switches are coupled. The assembly also comprises electronic control devices adapted to provide, as a function of the values of at least one input signal, logic control signals to the electronic switches so as to control, through the valves, the value of the pressure in the chamber. The control means comprise two processing and control devices independent of one another, both receiving the input signal and designed to execute strategies for controlling the pressure in the chamber, equivalent to one another.

A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.

A system including a supply valve disposed between a chamber and a pressure source, a discharge valve disposed between the chamber and an external atmosphere, a first control unit, and a second control unit. The first control unit coupled with the supply valve by a first switch and with the discharge valve by a second switch. The first control unit outputting signals to the first and second switches to control the supply and discharge valves. The second control unit coupled with the discharge valve by a third switch and a fourth switch, the second control unit outputting signals to the third and fourth switches to control the supply and discharge valves. The first control unit may include a first microcontroller to control the signals of the first control unit using an artificial intelligence (AI) neural network having artificial neurons arranged in layers and connected with each other by connections.

A brake control device controls a hydraulic brake that generates hydraulic braking force and an electric parking brake that generates parking braking force different from the hydraulic braking force. The brake control device comprises: a detection unit that detects a parking brake operation for causing the electric parking brake to generate the parking braking force; and a control unit that causes the electric parking brake to generate the parking braking force when the hydraulic braking force per wheel generated by the hydraulic brake, after decreasing below the minimum first braking force per wheel required for maintaining the vehicle stop state only by the electric parking brake, is less than the first braking force, in association with the parking brake operation having been performed in a state where the stop state is maintained only by a hydraulic brake operation for causing the hydraulic brake to generate the hydraulic braking force.

A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

A vehicle control device 1 has a prediction unit 122 that predicts a stopping position of a vehicle T, a gradient identification unit 123 that identifies the amount of gradient in the road surface at the stopping position predicted by the prediction unit 122, a weight identification unit 124 that identifies the weight of the vehicle T, and a braking control unit 125 that brakes the vehicle T by changing the pressure of the brakes of the vehicle T at a changing velocity determined on the basis of the amount of gradient identified by the gradient identification unit 123 and the weight of the vehicle T.

A braking system for a motor vehicle has a first and a second parking brake A first and a second control device each have a driver for driving at least the first and/or the second parking brake actuator. The first control device has a first arbitration unit to data whether a parking brake action should be carried out. The second control device has a second arbitration unit to receive parking brake request data and to ascertain from the received data whether a parking brake action should be carried out. The result of the second arbitration unit is fed to the first arbitration unit as parking brake request data and the result of the first arbitration unit is transmitted to the driver of the first and/or second control device for driving the first and second parking brake actuators.
