Trailer articulation angle estimation
This invention takes the advantage of existing radar, vision and ultrasonic sensors available for side blind spot detection, rear view, rear virtual bumper, and rear parking assist. Using a sensor fusion technique to combine the useful information from these sensors, the trailer articulation angles as well as trailer track width and tongue length is accurately estimated. When an active steering system is present, vehicle and trailer can be controlled with increased stability by applying the trailer information.

Avoiding blind spots of other vehicles
Aspects of the disclosure relate generally to detecting and avoiding blind spots of other vehicles when maneuvering an autonomous vehicle. Blind spots may include both areas adjacent to another vehicle in which the driver of that vehicle would be unable to identify another object as well as areas that a second driver in a second vehicle may be uncomfortable driving. In one example, a computer of the autonomous vehicle may identify objects that may be relevant for blind spot detecting and may determine the blind spots for these other vehicles. The computer may predict the future locations of the autonomous vehicle and the identified vehicles to determine whether the autonomous vehicle would drive in any of the determined blind spots. If so, the autonomous driving system may adjust its speed to avoid or limit the autonomous vehicle's time in any of the blind spots.

Blind spot detector system
InactiveUS6927677B2Digital data processing detailsAnti-collision systemsMicrocontrollerTransmitted power
A blind spot detector system adapted to the exterior of a vehicle comprising at least one infrared light emitting diode (LED), an infrared photodetector and demodulator, and a microcontroller. The output power of the infrared transmitter is linearly modulated, enabling the blind spot detector to determine the proximity of the detected object. Furthermore, the transmitter output is frequency modulated to screen out random infrared radiation that might adversely affect the operation of the infrared photodetector. The system is calibrated to the position of the attached vehicle by linearly increasing the output power of the transmitter until the rear quadrant of the vehicle is detected when the transmitter is outputting power at a pre-determined calibration level. During normal operation, an object detected while the transmitted power is greater than a predetermined lower threshold and less than the calibration level will activate a LED indicator on the system housing.
