The present invention provides a system and method for enabling a vehicle having adaptive cruise control to reduce its speed in a turn according to the vehicle's position within the turn as well as ignoring objects detected during the turn that are not in the vehicle's path. The method of the present invention includes the steps of operating the vehicle in an adaptive cruise control mode such that the vehicle is traveling at a set speed; determining whether the vehicle is in a turn in the vehicle's path by detecting change in the vehicle's lateral acceleration; and when the vehicle is determined to be in the turn, reducing the vehicle's speed according to the vehicle's position in the turn, monitoring for objects and maintaining the vehicle's speed if an object is positioned out of the path of the vehicle.

A system and method for enhancing the contrast within an image. An enhanced image can be generated in a real-time or substantially real-time manner from an initial image. A low-contrast image is enhanced, including the visibility of text within the low-contrast image. A logarithm transform method is used to enhance the overall contrast and visibility within the image. A power transform method is used to enhance the visibility and contrast of written text, symbols and other forms of signs within the enhanced image.

System or method for enhancing an image

A system and method for enhancing the contrast within an image. An enhanced image can be generated in a real-time or substantially real-time manner from an initial image. The pixel values of the initial image can be used to populate a histogram or otherwise serve as the basis for subsequent processing. A valley can be identified within the range of pixel values for use as a stretch metric used by a stretch heuristic to expand the contrast of the pixel values in the initial image by expanding the range of pixel values associated with the pixels in the histogram. In some embodiments, the initial image is first divided into image regions that are each associated with individualized processing. A bilinear interpolation step can then be performed to smooth the integrated image after the individualized processing is used to stretch the pixels within the individual image regions.

An improved IR occupant position detection system that provides accurate and reliable classification and position information at a speed sufficient to timely inhibit or otherwise control deployment of occupant restraints. A two-dimensional array of IR emitters is selectively activated to periodically illuminate two or more of predetermined viewing planes in the vicinity of a passenger seating area, and the reflected IR energy is detected by a photo-sensitive receiver and analyzed to detect the presence of an occupant, to classify the occupant, and to identify and dynamically track the position of the occupant's head/torso relative to predefined zones of the passenger compartment. Modulating the intensity of the emitted IR beams with a known carrier frequency, band-pass filtering the received signal, and synchronously detecting the filtered signal distinguishes the reflected IR energy from other signals picked up by the IR receiver. Additionally, a two stage adaptive control mechanism compensates for the variation in intensity of the reflected energy with distance between the emitter and the occupant. The emitter is implemented with orthogonal anode and cathode power rails with individual IR LED elements placed at each anode-cathode intersection. Optical dispersion within the package is greatly reduced by an opaque cover layer that effectively forms a well for each LED element.

The present invention provides for a wheel alignment procedure for a vehicle having a steer-by-wire steering system. The wheel alignment procedure includes determining an offset alignment value for a road wheel of a vehicle. The offset alignment value may be determined as the difference between the sensed wheel angle and a measured true angular position of the road wheel. The method further includes the step of adjusting the road wheel position as a function of the offset alignment value. Accordingly, the vehicle road wheel can be aligned by adjusting a calibration value in a controller without requiring physical adjustment of a mechanical linkage.

A weight estimation apparatus for the passenger seat of a motor vehicle, in which a single bladder substantially encompassing the seat bottom is evacuated and then inflated with a known volume of air. The average pressure in the bladder is determined to estimate the passenger weight. According to a first embodiment, the apparatus continues to monitor the average pressure, and the process is re-initiated if the average pressure changes by at least a predetermined percentage. According to a second embodiment, a bleed valve allows the pressure in the bladder to slowly escape, and the apparatus monitors the rate of change in pressure as a corresponding indication of passenger weight; in this embodiment, the process of evacuating and inflating is re-initiated if the monitored change in pressure does not correspond with the estimated weight. The sides of the bladder may be pleated to permit the bladder to expand under the weight of an occupant without stretching the bladder, and thereby affecting the average pressure. A temperature sensor may be disposed in proximity to the bladder provides a temperature signal for compensating the weight estimation for temperature variations. Also, the pressure sensor may be configured to sense the gage pressure--that is, the differential pressure between the bladder pressure and atmospheric pressure; alternatively, the pressure sensor may be configured to detect absolute pressure, and a second absolute pressure sensor responsive to atmospheric pressure may be used to compensate for changes in atmospheric pressure.

An improved weight estimation apparatus includes a closed elastomeric bladder filled with fluid and installed in the foam cushion of a vehicle seat bottom, with at least one pressure sensor installed in a closed exit port of the bladder. A temperature sensor disposed in proximity to the bladder provides a temperature signal, and a controller estimates the weight of the occupant based on the temperature and pressure signals. The pressure sensor is preferably configured to sense the gage pressure--that is, the differential pressure between the fluid and atmospheric pressure--at the center of gravity of the fluid in order to provide a stable output independent of changing atmospheric pressure and changing orientation of the bladder due to vehicle pitch and roll.
