  • Patent number: 8869831
    Abstract: A traction valve is provided for use in combination with a relay valve. The traction valve includes a body configured for connection to a housing of the relay valve and defining inlet, outlet and traction supply ports. A first fluid control valve used for traction control is supported on the body and includes a valve member that alternately permits and prevents fluid communication between the traction supply and outlet ports in the body. The body and the first fluid control valve are configured to receive any of a plurality of interchangeable second fluid control valves between the inlet port in the body and the first fluid control valve. Each of the plurality of interchangeable second fluid control valves is configured to perform a different function such that the traction valve assumes different configurations upon assembly of the various second fluid control valves with the body and the first fluid control valve.

  • Patent number: 8818673
    Abstract: When detecting unacceptably large airgaps between wheel speed sensors and their exciter rings on wheel ends of a vehicle, wheel speed sensor output is filtered and monitored to detect signal amplitudes that correspond to the airgaps. When signal peak amplitude below a predetermined threshold is detected, the airgap is too large. Wheel ends having unacceptably large air gaps are indicated to the driver or technician via blink sequences (e.g., on an electronic stability program (ESP) indicator light or other suitable indicator), wherein each wheel end is associated with a unique blink sequence.

  • Patent number: 8382060
    Abstract: A component to be mounted on a vehicle includes a housing, a pair of component mounting passages, defined in the housing, aligning with a pair of respective vehicle mounting passages when the component is any of a plurality of orientations with respect to the vehicle, and a component orientation element, on the housing. The component orientation element cooperates with a vehicle orientation element only when the component is in one of the plurality of orientations with respect to the vehicle. A hub on the component orientation element acts to tune the component orientation element for attenuating vibration received by the component orientation element from the vehicle.

  • Patent number: 6909408
    Abstract: A mounting assembly for a night vision display unit uses friction hinges to effectively position the display unit at a desired position relative to the vehicle operator. In a dashboard mounting arrangement, the friction hinge dampens movement of the display unit. In the visor mounted arrangement, the friction hinge assembly and catch assembly ensure convenient, effective storage and deployment of the visor or display unit without one component adversely impacting on the operation and use of the other component.

  • Publication number: 20030193613
    Abstract: A viewing system for use in connection with vehicles includes a camera (70), which may include night vision functionality, mounted in a side view mirror assembly (20). A forward facing aperture (24) is formed in a mirror housing (22) to provide an unobstructed opening for the camera. The camera is suitably positioned so as not to interfere with power adjustment features associated with the mirrors and to provide a perspective view substantially similar to that of the driver looking directly through the windshield. In addition, the camera is easily accessible for cleaning and aesthetically blends in with the vehicle.

  • Patent number: 6114952
    Abstract: A remote fault indicating unit (12) for an electronic system, such as a vehicle adaptive braking system, includes a series of visual indicators, such as light emitting diodes (50-59), on one surface of the housing and a computer serial port connector (13) for use when troubleshooting is done with a PC (18) equipped with the appropriate software. Each of the indicators (50-59) is activated in response to a predetermined malfunction sensed in the system, such as a defective speed sensor, defective modulator, or a defect in the electronic circuitry. The indicators (50-59) are reset with a switch (15) when the system is repaired. When the reset switch (15) is activated, all of the indicators (50-59) flash on and are then turned off. The reset switch (15) can also be activated for a longer period of time changing the ECU (14) configuration.
