An off-road vehicle includes a driveline, a control system, and a braking system. The driveline provides driveline power and driveline brake power to a first tractive assembly and/or a second tractive assembly. The control system stores vehicle information, determines driving instructions based on environment data, and determines speed references for tractive elements of the first and second tractive assemblies based on the driving instructions and the vehicle information. The braking system includes brakes and a braking subsystem. The brake subsystem operates the brakes to provide brake power to one or more components of the first and/or second tractive assemblies. The brake controller controls the brakes to selectively provide the brake power and the control system controls the driveline to selectively provide the driveline power and the driveline brake power based on current speeds of the tractive elements and the speed references to accommodate the driving instructions.

A bistable solenoid valve for a hydraulic brake system has a guide sleeve in which an upper immovable pole core is fixedly arranged and a closing element is displaceably arranged. The closing element is forced into a valve seat during a closing movement and lifts off from the valve seat during an opening movement, and is fixedly connected to a magnet assembly. An actuation of the movement of the closing element is performed by the magnet assembly via a coil positioned around and substantially surrounding the guide sleeve. A lower immovable pole core is fixedly arranged in the guide sleeve and the magnet assembly is positioned between the lower and the upper pole core.

The invention relates to a hydropneumatic valve for a vehicle train, comprising a hydraulic module, a pneumatic module and a mechatronic module, wherein the mechatronic module allows the pneumatic module to be activated independently of the hydraulic module.

An integrated braking device for a vehicle equipped with wheel brakes includes a reservoir, master cylinder, bi-directional pumps each using hydraulic pressure oil from the reservoir for generating hydraulic pressure in first direction to apply braking force to the wheel brakes or generating hydraulic pressure in opposing second direction to control the hydraulic pressure oil from flowing to the reservoir, a hydraulic motor for driving the bi-directional pumps, inlet valves for controlling a hydraulic pressure from flowing from the bi-directional pumps to the wheel brakes, traction control valves each disposed between the master cylinder and each bi-directional pump to control flow of the hydraulic pressure oil inside the master cylinder, and a braking control unit for braking the vehicle by transmitting a driving signal to solenoid valves in the integrated braking device, the bi-directional pumps, and the hydraulic motor to control a flow of the hydraulic pressure.

A vehicle braking calibration system and related method includes a valve fluidly coupled with a vehicle braking system of a vehicle. The valve is configured to move between an open position and a closed position to control an amount of a fluid that is directed out of the braking system. A sensor detects one or more characteristics of the fluid that is directed out of the braking system. A controller determines a state of the braking system based on the one or more characteristics of the fluid.

A 3-way solenoid valve and a brake system for vehicle including same. The 3-way solenoid valve includes a valve chamber, valve block, a first operation assembly, a valve seat, and a second operation assembly.

A brake system includes a brake command that is electronically transmittable to the brake system. It comprises a first and second electromechanical pressure generating units, that can implement the brake command and that are fluidically connected with one hydraulic brake circuit. Multiple actuator valves are assigned respectively to one brake actuator at a vehicle wheel and can either be pressurized or de-pressurized. Both pressure generating units are designed to supply sufficient brake pressure to actuate all brake actuators. During normal operation the first pressure generating unit supplies the requested brake pressure up to a normal maximal value. Additionally, potential peak brake pressures, that exceed the normal maximum value, are supplied by the second pressure generating unit. In event of failure of the second pressure generating unit the entire brake pressure is supplied by the first pressure generating unit, whereby the brake pressure is limited to the normal maximum value, and in an emergency mode when the first pressure generating unit fails the entire brake pressure in the brake circuit will be supplied via the second pressure generating unit, whereby the brake pressure is limited to the normal maximum value or an emergency maximum value.
