PLUG-TYPE DRIVER ASSISTANCE DEVICE
A plug-type driver assistance device includes an external brake module and an auxiliary control module. The external brake module includes a hydraulic pump and a control valve group, the control valve group includes an inlet valve and an outlet valve, and the hydraulic pump is connected between the inlet valve and the outlet valve. The auxiliary control module includes a receiving unit, a processing unit and an output unit. The processing unit selectively switches to the original vehicle control mode or the assist driving mode. The original vehicle control mode means that the processing unit receives the accelerator pedal signal and controls the output unit to output the accelerator pedal signal. The assist driving mode means that the processing unit receives the surrounding information of the vehicle, and generates an analog pedal signal and an analog braking signal.
Braking control device and braking control method
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.
Electric-brake controller and vehicle brake system
An electric-brake controller includes an antilock controller configured to control a pressing force of an electric brake. The electric brake includes a pressing member that is advanced by rotation of an electric motor in a forward direction to press a friction member against a brake rotation member. The electric brake includes a return spring that applies a spring force such that the pressing member is moved away from the brake rotation member. The antilock controller includes a pressing-force reducer that reduces the pressing force. The pressing-force reducer includes: a reverse-rotation-current supplier that supplies reverse-rotation current for rotating the electric motor in a reverse direction for a reverse-rotation-current supply time; and a forward-rotation-current supplier that supplies forward-rotation current, for rotating the electric motor in the forward direction, to the electric motor after the reverse-rotation current is supplied for the reverse-rotation-current supply time.
Valve block for electronic control brake system
A valve block for an electronic brake system is disclosed. The valve block is configured to have two hydraulic circuits, a plurality of accommodating bores in which valves, pumps, low pressure accumulators, pressure sensors, and a motor are installed in order to control the braking hydraulic pressure supplied from a master cylinder to a wheel cylinder installed in each wheel, and a plurality of flow passages for connecting the plurality of accommodating bores, wherein on opposite side surfaces of the valve block, pump accommodating bores are formed symmetrically to each other to accommodate the pump, and first damping bores having an arrangement parallel to the pump accommodating bores are formed above the pump accommodating bores, wherein on an upper surface of the valve block, a pair of second damping bores is formed so as to be positioned above the first damping bores, and wherein first hydraulic lines are formed in a straight line from a bottom surface of the pair of second damping bores toward a bottom surface of the valve block, so that a discharge side of the pump accommodating bores and a suction side of the first damping bores, and a discharge side of the second damping bores and the bottom surface of the second damping bores are connected by the first hydraulic lines.
TRACTOR POWERED PRESSURIZED SEMI-TRACTOR AND TRAILER WASHER
An on-board pressurized washing system that utilizes a semi-tractor or trailer's compressed air brake line as its source of compressed air. When the tractor is parked, the air brake lines may be disconnected from the trailer and hooked up to the pressurized washing system. The system is fully mobile and does not need an external power source or water line during operation. The water from the water tank and the compressed air are sprayed separately or together from a spray wand to meet cleaning and sanitation needs of truck drivers in any location when they may not have access to electricity or a water source.

Method for adjusting the brake pedal counter force in a vehicle
A method for adjusting the brake pedal counter force in a vehicle with a hydraulic vehicle brake and an electromechanical brake device includes modulating the brake pressure during the simultaneous operation of the hydraulic vehicle brake and the electromechanical brake device such that the brake pedal counter force follows a predetermined target profile.
Method for operating a brake system of a motor vehicle, and brake system
A method for operating a brake installation of a vehicle. A first electrically controllable pressure provision device provides brake pressure for actuating hydraulically actuatable brakes. A first electronic open-loop and closed-loop control unit, and a first pressure detection device, measures brake pressure provided by a primary brake system. A secondary brake system between the primary system and a part of the wheel brakes has a second electrically controllable pressure provision device provides brake pressure for actuating at least the part of the brakes. A second electronic open-loop and closed-loop control unit, and at least one second pressure detection device, the signals of which are processed in the second electronic open-loop and closed-loop control unit. The secondary system monitors the primary system based on signals from the second pressure detection device and on a predefined brake pressure demand to build up a brake pressure corresponding to the predefined brake pressure demand.
Methods and apparatus to detect warped rotors based on brake pressure
Methods and apparatus are disclosed that detect warped rotors. An example apparatus includes a controller configured to receive a brake pressure and one or more wheel parameters of a vehicle associated with a first braking event, determine a presence of a warped rotor based on a comparison of the brake pressure to a threshold pressure, and identify a wheel of the vehicle associated with the warped rotor based on the brake pressure and the one or more wheel parameters.
