Abstract: A brake controller is disclosed for a towed vehicle braking system. The controller is adapted to be mounted in a towing or a towed vehicle having a longitudinal axis for generating a braking control signal to the towed vehicle braking system. The controller comprises an inertial sensor including plural sensor axes adapted to be mounted in an undefined orientation relative to the longitudinal axis for generating sensor data associated with each sensor axis. The controller also comprises a memory device for storing the sensor data associated with each sensor axis and a processor for processing the sensor data with the braking control signal to evaluate orientation of the inertial sensor relative to the longitudinal axis.

Abstract: A brake control system has a manual fluid pressure source and a power fluid pressure source. A fluid pressure actuator forms an X-pipe having a first channel and a second channel. The power fluid pressure source supplies the operating fluid to each wheel by using the first channel and the second channel. A channel system including the first channel and a channel system including the second channel can be isolated from each other by an isolation valve. The fluid pressure actuator includes a regulation unit configured to regulate a state of supplying the operating fluid such that a difference between a state occurring when the operating fluid is supplied to one of the first channel and the second channel after passing through the isolation valve, and a state occurring when the operating fluid is supplied to the other channel without passing through the isolation valve, is reduced.

Abstract: A braking system for a floor conveyor, which features at least one travel motor for at least one driven wheel, an electric steering control for at least one steered wheel, a service brake with a braking transmitter generating a braking signal and an electromagnetically releasable spring brake as an emergency stop brake, which is amongst others actuable when an error signal is generated in the steering control or a braking signal otherwise, which further features a superordinated vehicle control for various functions of the floor conveyor and a battery for supplying the individual electric consumers, wherein the steering control actuates a first switch at an error signal, which cuts off the electric connection between the battery and the emergency stop brake, wherein an additional switch is connected in series with the first switch and is actuable by a PWM actuator of the vehicle control, and a control line is connected between the steering control and the vehicle control, such that both switches are switched

Abstract: A three-wheeled vehicle having a pair of front wheels and a single rear wheel is provided with a roll-related reactive system. The roll-related reactive system provides braking of at least one of the front wheels independent of braking initiated by an operator of the vehicle.

Abstract: A brake fluid pressure relief assembly (50) for a brake system (10) including a pedal assembly (12) employs first and second valves (52, 54) to provide controlled collapse of a brake pedal pad (14) when both a predetermined deceleration limit is exceeded and a predetermined pressure level is exceeded in a hydraulic brake fluid. The first valve (52) is actuated by an inertial mass (84) acting against a first spring (86). With the first valve in the open position, hydraulic fluid passes into a reservoir (68) whose volume is a dependent on the position of the second valve (54). The second valve (54) opens when the fluid pressure in the reservoir exceeds a predetermined pressure limit and compresses a piston (100) against a second spring (114). Accordingly, the forces that can be communicated through the pedal system 10 are reduced during a collision.

Abstract: A yaw control system for an automotive drivetrain includes an equal torque differential, an engine-driven hydraulic pump, and hydraulically actuated control brakes operable to apply a resistive torque to either a left or right axle of the driven wheels. An acceleration-responsive control valve actuates one of the control brakes according to the direction of lateral acceleration of the vehicle. The control valve includes an inertial or seismic mass that moves a valve member to connect or disconnect the control brakes from the hydraulic pump. The control brakes are attached to the vehicle chassis so the resistive torque is reacted through the chassis, thereby inducing a yaw moment that coincides with and assists the turning of the vehicle.
