AUTOMATIC CONTROL BRAKING SYSTEM FOR VEHICLES
A braking system for vehicles having a master cylinder, and at least one braking device. The master cylinder has a first and a second output circuit, containing the same brake fluid. The first output circuit is intercepted by a first control valve fluidically connected to a braking simulator and to the at least one braking device so as to alternately connect the first output circuit to the braking simulator or to the at least one braking device for its actuation. The second output circuit is fluidically connected to the at least one braking device for its actuation, an automatic hydraulic actuation unit operatively connected to the master cylinder by a hydraulic actuation circuit containing an actuation fluid distinct from the brake fluid and fluidically separated from this. And, at least a processing and control unit of the system that supervises the operation of the braking systems.
ELECTRONICALLY PRESSURE-CONTROLLABLE BRAKING SYSTEM AND METHODS FOR CONTROLLING AN ELECTRONICALLY PRESSURE-CONTROLLABLE BRAKING SYSTEM
An electronically pressure-controllable braking system and methods for controlling an electronically pressure-controllable braking system. Each wheel brake of the braking system is connected respectively to at least two brake circuits, pump units and valve devices of one brake circuit are operable respectively independently of the pump units and the valve devices of the respective other brake circuit. This provides a cost-effectively and compactly designed redundant braking system, which is suitable for use in autonomously, i.e., driverlessly drivable, motor vehicles.
Hydraulic braking system
An external force-supported hydraulic braking system of a wheeled vehicle includes two brake circuits each having a main brake line configured to be connected to a pressure-carrying supply line or to a pressureless return line via a brake valve and further having a number of wheel brake lines branching from the main brake line and including a valve assembly of a TCS system. The valve assembly of the TCS system has a single TCS control valve formed as a 6/2-way magnetic switching valve configured to, in a non-actuated state, block a pressure-carrying main pressure line against two bypass lines each leading directly to a respective main brake line, and connect the two return lines to a pressureless collective line, and further configured to, in the actuated state, connect the main pressure line to the two bypass lines and block the two return lines against the collective line.
BRAKING SYSTEM WITH SECOND BRAKE
A method and a braking system are described. The braking system includes a rotor connected to a wheel of the vehicle, a speed sensor measuring a vehicle speed, a first brake including a first piston and at least one brake pad coupled to the rotor, a second brake including a second piston and a brake pad coupled to the rotor, and a brake controller configured to activate the first piston to engage or disengage the first brake with the rotor, receive signal from the speed sensor to determine a stopping distance, compute a braking threshold based on the stopping distance, and activate the second piston to engage or disengage the second brake with the rotor based on the braking threshold.
BRAKE UNIT
A brake unit that allows the vehicle to evacuate safely in the event of brake failure while maintaining a braking performance. The brake unit is mounted on a vehicle together with a motor drive unit 2 to control brake force in accordance with a stroke of a brake pedal and a pedal force. Each brake system comprises: a stroke sensor; a pedal force sensor; a brake mechanism applying brake force to a driveshaft; a controller controlling the brake mechanism based on the stroke and the pedal force; and a powersource supplying electricity to the brake mechanism and the controller. The first controller 13 and the second controller support each other to control brake force.
HYDRAULIC BRAKING SYSTEM
An external force-supported hydraulic braking system of a wheeled vehicle includes two brake circuits each having a main brake line configured to be connected to a pressure-carrying supply line or to a pressureless return line via a brake valve and further having a number of wheel brake lines branching from the main brake line and including a valve assembly of a TCS system. The valve assembly of the TCS system has a single TCS control valve formed as a 6/2-way magnetic switching valve configured to, in a non-actuated state, block a pressure-carrying main pressure line against two bypass lines each leading directly to a respective main brake line, and connect the two return lines to a pressureless collective line, and further configured to, in the actuated state, connect the main pressure line to the two bypass lines and block the two return lines against the collective line.
HYDRAULIC MULTI-CIRCUIT POWER BRAKE SYSTEM
An electrohydraulic multi-circuit power brake system for autonomous driving. The power brake system includes a piston-cylinder unit for each brake circuit, using which the brake circuits are connected to a common power brake pressure generator. In the event of a failure of the power brake pressure generator, the power brake system can be actuated with a hydraulic pump of a slip control system of the vehicle brake system.
