A system for a vehicle for controlling/adjusting the wheel behaviour of at least one vehicle wheel comprises at least one unit for determining the wheel vertical force of at least two vehicle wheels which are mounted on the same axle of the vehicle. The system is adapted to determine for each of the at least two vehicle wheels at least one parameter indicative of the wheel behaviour. The system is further adapted to determine, on the basis of the wheel vertical forces determined by the unit for determining the wheel vertical force for the at least two vehicle wheels, at least the vehicle wheel with the higher wheel vertical force. The system is further adapted to set the at least one parameter indicative of the wheel behaviour determined for the at least one vehicle wheel with the higher wheel vertical force as the target value for the vehicle wheel with a lower wheel vertical force.

A brake system for actuating a pair of front wheel brakes and a pair of rear wheel brakes is selectively operable during a manual push-through mode. A primary power transmission unit actuates at least one of wheel brakes in a normal braking mode. A secondary power transmission unit actuates the front wheel brakes in a backup braking mode. A primary electronic control unit controls at least one of the primary power transmission unit and a pair of rear brake motors. A secondary electronic control unit controls at least one of the secondary power transmission unit and the rear brake motors. An ABS modulator arrangement is hydraulically interposed between at least one of first and second three-way valves and at least a selected wheel brake. A multiplex control valve arrangement is hydraulically interposed between the secondary power transmission unit and the front wheel brakes.

A brake system includes a reservoir and a master cylinder operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. The master cylinder is selectively operable to generate brake actuating pressure at an output for hydraulically actuating a pair of hydraulically actuated wheel brakes in a manual push-through operation. A power transmission unit is configured to selectively generate pressurized hydraulic fluid for actuating the pair of hydraulically actuated wheel brakes. First and second two-position three-way valves are hydraulically connected to respective ones of the pair of hydraulically operated brakes and to both the master cylinder and the power transmission unit. The first and second three-way valves each are configured to selectively switch the respective hydraulically operated brake to receive fluid from a selected one of the master cylinder, in a backup braking mode, and the power transmission unit, in a normal non-failure braking mode.

A hydraulic assembly of a traction control system of a hydraulic vehicle brake system includes a hydraulic block, a motor block, and a control device. The hydraulic block includes at least one electric hydraulic valve and at least one electric hydraulic pump arranged therein. The motor block includes an electric motor arranged therein. The electric motor is configured to drive the at least one hydraulic pump. The control device is configured to control the at least one hydraulic valve, the at least one hydraulic pump, and the electric motor. The control device has two structurally separate control units, which include a first control unit with signal components and a second control unit with power components.

A device and a method for decelerating a vehicle having a front-loading device has a brake system and sensors for measuring the mass and the center of gravity of a load. An electronic evaluation and control unit evaluates the sensor data to determine a maximum brake deceleration in forward travel, in order to prevent the vehicle tilting about the front axle. At least one sensor of the brake system generates a sensor signal in an emergency braking situation for triggering an emergency braking operation, in which the delimitation or reduction of the effective brake pressure in the wheel brake cylinders of the front axle is canceled and, with the exception of an ABS control operation, the full brake pressure is introduced in a controlled manner by way of a primary brake valve into the wheel brake cylinders of the front axle.

It is possible to prevent occurrence of a resonance phenomenon of a hydraulic unit and to improve attachability/detachability of the hydraulic unit to/from a bracket. A support section (42, 43) includes: a fixture member (80) that is fixed to a housing (30) for a hydraulic unit (10); and a vibration absorbing member (75) that is interposed between the housing (30) and a bracket (41) and has a through-hole (75a) through which the fixture member (80) passes. The vibration absorbing member (75) includes two vibration absorbing members (75B, 75C, 75D) having different rebound resilience from each other. In a state where the vibration absorbing member (75) is partially accommodated in a recessed section (47) of the bracket (41), the vibration absorbing member (75) is held between the housing (30) and the bracket (41).

A method for operating an electromechanical braking system for a transportation vehicle having a brake pedal, a brake master cylinder, and an electromechanical brake booster. The electromechanical brake booster includes an actuator motor for increasing or decreasing the pedal force on the brake master cylinder to boost or reduce the braking power accordingly. A change in the boosting force of the electromechanical brake booster is limited to avoid uncontrolled changes of the brake boosting.

An electropneumatic control module for an electronically controllable pneumatic brake system for a vehicle combination with a tractor vehicle and a trailer vehicle includes a pneumatic reservoir input, which is connectable to a compressed-air reservoir, a trailer control unit, which has a trailer control valve unit with one or more electropneumatic valves, a trailer brake pressure port and a trailer supply pressure port, an immobilizing brake unit, which has a spring-type actuator port for a spring-type actuator for a tractor vehicle and an immobilizing brake valve unit with one or more electropneumatic valves, and an electronic control unit for controlling the trailer control valve unit and the immobilizing brake valve unit. The trailer control unit has a first relay valve, which has a relay valve working input connected to the reservoir input, a relay valve output connected to the trailer brake pressure port, and a relay valve ventilation output.

A braking system for a vehicle, including: at least one pressure regulating module to set a setpoint brake pressure for at least one brake cylinder of a vehicle wheel; at least one wheel speed sensor to detect the wheel slip of the one vehicle wheel; at least one pressure control valve, assigned to the brake cylinder of a wheel, to control the brake pressure applied at the brake cylinder depending on the wheel slip; and a central processing unit to control the at least one pressure regulating module and the at least one pressure control valve at least starting from a brake signal and the detected data of the at least one wheel speed sensor, which has a direct connection to the central processing unit to transmit data detected by the wheel speed sensor.

A cuboid hydraulic block of a slip control system of a hydraulic vehicle brake system has a lateral face, an opposite lateral face, at least two long sides, a short side, and an opposite short side. All receptacles for solenoid valves of the slip control system are disposed in the lateral face of the hydraulic block. Receptacles for hydraulic accumulators of the slip control system and connecting bores for a master brake cylinder are disposed in the opposite lateral face of the hydraulic block. Receptacles for hydraulic pumps of the slip control system are disposed in the long sides of the hydraulic block.
