摘要： A dead-reckoning guidance system determines a vehicle-speed of the host-vehicle based on wheel-signals from the one or more wheel-sensors; determines a distance-traveled by the host-vehicle during a time-interval since prior-coordinates of the host-vehicle were determined; determines a heading-traveled of the host-vehicle during the time-interval since the prior-coordinates of the host-vehicle were determined; determines present-coordinates of the host-vehicle based on the distance-traveled and the heading-traveled; determines when the vehicle-speed is greater than a speed-threshold; determines when the heading-traveled differs from a cardinal-direction by both greater than a noise-threshold and less than an angle-threshold; and in response to a determination that both the vehicle-speed is greater than the speed-threshold and that the heading-traveled differs from the cardinal-direction by both greater than the noise-threshold and less than the angle-threshold, determines a coordinate-correction to apply to the present-coordinates, said coordinate-correction determined in accordance with the distance-traveled and the cardinal-direction.

摘要： A system for adjusting vehicle driver settings includes vehicle nodes configured to receive signals from a key fob or other portable wireless device, and a processing system for evaluating height information of the keyfob or other device. The processing system is configured to receive the height information and evaluate whether the wireless device is likely being carried within an article of clothing of the driver. A vehicle settings controller system accesses a settings database to obtain vehicle settings related to a particular wireless device height and implements initial vehicle settings upon a driver approaching the vehicle.

摘要： A system for generating a 3D reflective surface map includes a positioning system, one or more antennas co-located with the positioning system, and a processing system. The positioning system calculates a position estimate. The one or more antennas co-located with the positioning system are configured to receive at least one reflected global navigation satellite system (GNSS) signal associated with a respective GNSS satellite and wherein a pseudo-range to the GNSS satellite is determined based on the reflected GNSS signal. The processing system is configured to receive the position estimate and the pseudo-ranges calculated with respect to each reflected GNSS signal, wherein the processing system maps a reflective surface based on the calculated pseudo-range provided by the reflected GNSS signals, the position estimate, angle-of-arrival of each reflected GNSS signal, and known satellite location of each respective gnss satellite.

摘要： A vehicle controller includes at least one input configured to receive sensor signals from a plurality of sensors configured to determine vehicle dynamic information and at least one input configured to receive sensor signals from a plurality of sensors configured to determine external vehicle information Included in the vehicle controller is a memory and a processor. The memory stores instructions for executing a vehicle positioning system and a driver assistance system using the controller. An output is configured to output a safe to pass condition in response to the controller determining an available vehicle power meets or exceeds an estimated power requirement for a passing operation.

摘要： A dual-antenna positioning system includes a first GNSS antenna/receiver, a second GNSS antenna/receiver, and a GNSS processor system. The first GNSS antenna/receiver is located at a first position and calculates a first pseudo-range based on a received GNSS signal. The second GNSS antenna/receiver is located at a second position a known distance from the first GNSS antenna/receiver, wherein the second GNSS antenna/receiver calculates a second pseudo-range based on a received GNSS signal. The GNSS processor system configured to receive the first pseudo-range and the second pseudo-range, wherein in response to the GNSS processor system identifying one of the first and second pseudo-ranges as erroneous and one of the first and second pseudo-ranges as valid, the GNSS processing system calculates a corrected pseudo-range and utilizes the corrected pseudo-range and the valid pseudo-range to determine GNSS position fix estimates for the first GNSS antenna/receiver and the second GNSS antenna/receiver.
