Abstract: A traction control system is provided for a vehicle having wheels driven on a primary axle via an engine, and wheels on a secondary axle torsionally isolated from the engine. Wheel speed sensors and brakes are provided for each wheel. A motor/hydraulic pump is operatively associated with each secondary axle wheel for selectively powering the secondary axle wheel or being regenerativly powered by the secondary axle wheel for regenerative braking. A clutch is provided to connect each secondary axle wheel with the secondary axle wheel's motor/hydraulic pump. An accumulator is provided to hydraulically power the secondary axle wheels and to accept regenerative pressure from the secondary axle wheel's motor/hydraulic pump. A wheel valve is provided for each respective secondary axle wheel for selectively connecting the secondary axle wheel's motor/hydraulic pump with the accumulator. A controller is provided to control the primary axle and secondary axle wheels.

Abstract: One general aspect includes a method of diagnosing a mechanical problem on a vehicle including: collecting data from individual sensors, determining from the data whether is an NVH issue on the vehicle, and providing an alert when there is an NVH issue detected.

Abstract: A steering system which is capable of being controlled by a redundant brake system, which includes a primary brake control module, a secondary brake control module, and a plurality of brake units controlled by the primary brake control module or the secondary brake control module. There is at least one hydraulic motor connected to a component of the steering system, and the fluid pressure in the hydraulic motor is controlled by the secondary brake control module. The wheels of the steering system are configured to make a right-hand turn when the secondary brake control module operates the hydraulic motor during a first mode of operation, and the wheels of the steering system are configured to make a left-hand turn when the secondary brake control module operates the hydraulic motor during a second mode of operation.

Abstract: A pump includes a pump housing with a bore, an inlet and an outlet, a piston movable in the bore, and an inlet valve and an outlet valve which are formed by a cup seal. The piston has a portion of a large diameter and a portion of a small diameter, each of the portions extending through one of the cup seals, whereby a pump chamber is provided between the cup seals. In a first embodiment, the cup seal encompassing the large diameter is the inlet valve and the cup seal encompassing the small diameter is the outlet valve, and the cup seals are arranged in an annular radial groove provided in the bore. In another embodiment, the cup seal encompassing the large diameter is the outlet valve and the cup seal encompassing the small diameter is the inlet valve. Here the cup seals are arranged in an annular radial groove provided on the piston. For noise reduction purposes, the piston is tapered from the large diameter toward the small diameter.

Abstract: A fault controller for a brake system includes a control display having a plurality of identifying labels displayed thereon corresponding to predetermined brake system fault mode options. A plurality of switches corresponding to the identifying labels and selectively setable to activate and deactivate conditions are on the control display. Fluid control valves are disposed along brake lines between the master cylinder and the wheel brakes. There are electrical connections between the switches and fluid control valves wherein setting one of the switches to the activate condition activates a corresponding fault mode of the brake system. An enable switch on the controller, if included, must be set to an "enable" condition for the fault controller to affect brake operation.

The diaphragm includes a beaded peripheral portion which is sealingly engaged between the walls and the beaded portion is adhesively secured to at least one of the walls to prevent movement during assembly.

Abstract: A disc brake for the wheel of a motor vehicle includes a rotor mounted to the wheel, and a caliper straddling the rotor and supporting a brake pad on either side thereof. In order to accommodate packaging constraints within the wheel's rim, the outboard pad and the rotor's outboard friction surface are both positioned radially inwardly of the inboard pad and inboard rotor friction surface. A hydraulic piston located in the inboard portion of the caliper first urges the inboard pad along the piston's longitudinal axis into initial engagement with the rotor's inboard friction surface, whereupon the piston acts through the caliper's bridge and finger area to urge the outboard pad into engagement with the rotor's outboard friction surface. The effective radius of each pad is less than the radial offset of the piston's longitudinal axis from the rotational axis of the wheel and rotor so as to reduce the bending moment applied to the rotor upon braking.
