Abstract: A brake fluid pressure control device controls brake fluid pressures through control of fluid pressure control valves operated in accordance with control signals from, for example, a computer. Signal lines for supplying control signals to control circuits controlling coils of linear valve devices for some wheels (e.g., front-left and rear-right wheels) are connected to a brake ECU by a connector, and signal lines for supplying control signals to the control circuits controlling coils of linear valve devices for other wheels (e.g., front-right and rear-left wheels) are connected to the brake ECU by a different connector. Thus, even if one of the connectors starts operating abnormally, it is possible to supply control signals via the signal lines connected by the other connector and control linear valve devices for some of the wheels (e.g., a pair of diagonally located wheels).

Abstract: A hydro-pneumatic suspension system includes one or more hydraulic suspension cylinders mounted between the vehicle body and the axle. Each cylinder includes a piston chamber and rod chamber, each of which are connected to an accumulator and which can be connected to a pressure source and a tank by valve systems. The valve system for the rod chamber includes a first solenoid valve and a hydraulically and electrically actuated proportional pressure adjusting valve. The proportional valve is exposed to rod chamber pressure and to tank pressure. The rod chamber pressure can be applied on the proportional valve either directly as control pressure or can be detected with a sensor, and can be used to control the proportional valve. Such a system can influence the dependency of the suspension stiffness on the axle load and can be used to adjust the stiffness to ballast conditions and operating or driving states.

Abstract: A brake pedal feel simulator is provided which eliminates the simulation force during emergency, non-assisted and failure conditions. The brake pedal feel simulator generally comprises a spring, a spring seat and a spring stop. The spring is operatively connected to the brake pedal for providing the simulation force, while the spring seat receives an end of the spring. A spring stop is operable between an extended position and a retracted position to prevent and permit rearward axial translation of the spring seat. By permitting rearward axial translation of the spring seat, a simulation force provided by the spring is removed so that there is essentially no resistance to translation of the brake pedal, thereby improving the operator's ability to brake the vehicle.

Abstract: An arrangement with a height-adjustable component includes an approximately vertically extending upright which bears the component, the upright including a pneumatic spring. The pneumatic spring has a cylinder having a bottom end connected to a fixed part of the arrangement. A piston displaceably arranged in the cylinder subdivides the cylinder into a bottom cylinder chamber and a top cylinder chamber and has a piston rod at one end. The piston rod projects through the top cylinder chamber and is guided out of the top end of the cylinder and bears the component at its free end. The top and bottom cylinder chambers are filled with a gas filling, under positive pressure, which subjects the piston to an upwardly directed push-out force corresponding approximately to the opposing weight-induced force of the component. A valve allows a gas flow from the top into the bottom cylinder chamber and blocks the same in the opposite flow direction.
