Abstract: A corner or end module for assembly on a vehicle body comprises a wheel(s), a frame having connection points for removably securing the corner module to the vehicle body, a drive system capable of providing torque to drive the wheel(s), a brake system connected to the wheel(s) capable of braking the wheel(s), a suspension system located between the frame and the wheel(s), a steering system connected to the wheel(s), capable of providing a steering input for the wheel(s), and a communication system capable of communicating from at least one of a drive controller, brake controller, and steering controller of the corner or end module with one of: another corner or end module, a vehicle controller; an autonomous drive controller; another vehicle, infrastructure, and a wireless data server.

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 disc brake for a motor vehicle includes a rotor mounted to a wheel and rotatable about a first axis therewith; a pair of parallel-spaced pins removably mounted to the vehicle chassis so as to extend in a direction generally parallel to the first axis; a pair of brake shoes having slots for receiving the pins on either side of the rotor so as to place brake linings respectively mounted on the pins in opposition with complementary annular friction surfaces on either side of the rotor; and a caliper slidably supported by the two pins so as to straddle the rotor and both brake shoes, respectively. The slots of the brake shoes are defined in part by a finger configured to deflect responsive to a brake load and the deflection of the finger enables the sequential engagement of the brake shoes against the pins.
