    Abstract: A vehicle hydraulic braking system comprising: a service braking system (A) powered by a hydraulic generator (3); an emergency braking system (B); a manual control element (D, 16); a master cylinder (17); at least one safety valve (26, 28); a simulator (M) used, as the manual control element moves forward (D, 16), to oppose a reaction that reflects the braking process, said simulator comprising a cylinder (30) wherein a simulator piston (31) slides and which is subject, in one direction, to a liquid pressure from the master cylinder (17) and, in the opposite direction, to an opposing force dependent on the stroke of the manual control element; inlet (9a-9d) and outlet (14a-14d) solenoid valves connected to the wheel brakes (2a-2d); sensors (8, 13a-13d, 24, 29) used to capture different braking parameters; and a computer (C) used to control the solenoid valves. The counteracting force in the simulator (M) results from the action, on one surface of the simulator piston (31), from a modulated pressure established on the basis of the liquid pressure supplied by the hydraulic generator (3) and controlled by the computer (C) according to a given law, which can be modified at will.

    Abstract: A spring applied, hydraulically released (SAHR) parking and emergency brake system (30) can be manually overridden to permit towing or assisted vehicle transport when charge pump pressure is unavailable for the brakes (40), and is reset either automatically when charge pump pressure becomes available or manually. Override is made possible by a manual override assembly (50) that includes a manually-actuated hand pump (86) and an override valve (84). The override valve (84) is manually actuated to isolate the brake release actuators (44) and the outlet of the hand pump (86) from the system's reservoir (64) and is reset to its open position in response to the presence of hydraulic pressure at a designated location of the braking system. Automatic reset of the override valve (84) preferably is effected by the supply of pressurized fluid to a previously-unpressurized port of the override valve (84). The hand pump (86), override valve (84), and any other brake control valve(s) of the braking system (30) preferably are incorporated into a single control module (52).

    Abstract: An automatic braking system and method are provided for controlling the automatic operation of a pneumatic (air) brake system installed on commercial highway vehicles and the like, particular heavy trucks and buses. When a possible collision is detected or an object is detected in proximity to at least one side and/or end of the vehicle, the system automatically operates the existing, factory installed air braking system of the vehicle to avoid a collision or mitigate the collision impact by concurrently pressurizing each of the rear and front pneumatic service brakes of the vehicle. Pressing the existing vehicle brake pedal deactivates the automatic braking system, thereby permitting the driver to take over control of braking at any time.
