An instrument cluster for a motor vehicle includes a dial surface having a plurality of indicia located thereon. A pointer contacts the dial surface and is configured to rotate with respect to the dial surface. Piezoelectric material is disposed on one of the dial surface and the pointer. The piezoelectric material is configured to deform due to contact between the pointer and the dial surface.

A method optimizes trailer braking gain for a trailer that is towed behind a vehicle. The method receives an operator selected trailer gain. During a braking event, braking data from at least one sensor is received. Based on the received data and the selected trailer gain, an output trailer gain is provided. During the braking event, pressure in a master cylinder of a vehicle and an actual deceleration of the vehicle is monitored. The method determines if the actual deceleration is sufficient for the monitored master cylinder pressure and if not sufficient, the output trailer gain is automatically adjusted to provide an optimized trailer gain to brakes of the trailer until the actual deceleration of the vehicle matches an expected deceleration at the monitored pressure value.

A hitch assist system for a vehicle comprises a camera mounted to view a reverse path of a vehicle, an input device connected for the hitch assist system, and a controller. The controller includes instructions for detecting a trailer proximate to a vehicle with the camera, determining a vehicle hitch ball location, determining a trailer hitch location, and calculating a vehicle path from an initial position to a final position. The vehicle hitch ball is laterally aligned with the trailer hitch in the final position. The controller also includes instructions for calculating the steering and braking maneuvers necessary to move the vehicle along the path to the final position and sending instructions to a vehicle steering system and a vehicle brake system to perform the calculated maneuvers.


A pressure sensor device with a MEMS piezoresistive pressure sensing element attached to an in-circuit ceramic board comprises a monolithic ceramic circuit board formed by firing multiple layers of ceramic together. The bottom side of the circuit board has a cavity, which extends through layers of material from the ceramic circuit board is formed. A ceramic diaphragm, which is one of the layers, has a peripheral edge. The diaphragms thickness enables the diaphragm bounded by the edge to deflect responsive to applied pressure. A MEMS piezoresistive pressure sensing element attached to the top side of the ceramic circuit board generates an output signal responsive to deflection of the ceramic diaphragm. A conduit carrying a pressurized fluid (liquid or gas) can be attached directly to the ceramic circuit board using a seal on the bottom of the ceramic circuit board, which surrounds the opening of the cavity through the bottom.

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 wheels motor/hydraulic pump. An accumulator is provided to hydraulically power the secondary axle wheels and to accept regenerative pressure from the secondary axle wheels motor/hydraulic pump. A wheel valve is provided for each respective secondary axle wheel for selectively connecting the secondary axle wheels motor/hydraulic pump with the accumulator. A controller is provided to control the primary axle and secondary axle wheels. The controller commands braking and powering of the primary and secondary axle wheels during low traction events.

Acoustic noise in an audio signal is reduced by calculating a speech probability presence (SPP) factor using minimum mean square error (MMSE). The SPP factor, which has a value typically ranging between zero and one, is modified or warped responsive to a value obtained from the evaluation of a sigmoid function, the shape of which is determined by a signal-to-noise ratio (SNR), which is obtained by an evaluation of the signal energy and noise energy output from a microphone over time. The shape and aggressiveness of the sigmoid function is determined using an extrinsically-determined SNR, not determined by the MMSE determination. The extrinsically-determined SNR is obtained from a long term history of previously-determined speech presence probabilities and a long term history of previously-determined noise histories.

A gate opening system for a vehicle comprises a gate for the vehicle moveable between an open position and a closed position relative to a vehicle body and a gate actuator secured to the vehicle and the gate to actuate movement of the gate between the open position and the closed position. A camera is mounted to the vehicle and facing in an external direction provide a view of an area proximate to the vehicle. An ECU is connected to the camera to detect a predetermined action by a vehicle operator based upon image analysis of the camera image. A remote keyless entry system is also connected to the ECU and the gate actuator, wherein the remote keyless entry system activates the gate actuator to move the gate from the closed position to the open position when the ECU determines that the predetermined action has occurred.

A light guide assembly for illuminating two gauges utilizing a single light guide includes of a two pairs of light sources such as LEDs, OLEDs, quantum dots or other useful light sources functioning to emit light in opposite directions. A light guide receives the light emitted by the LEDs and leaks light out of its open surfaces. A protrusion from the light guide which leaks light in a specific orientation depending on its geometry illuminates a second gauge. An opaque gauge which covers the main portion of the light guide and is located above the light guide.
