CALIBRATION SYSTEM FOR VEHICLE RADAR SYSTEM
First Claim
1. A calibration system for calibrating a radar sensing system for a vehicle, said calibration system comprising:
- at least one calibrating radar transmitter spaced from a location where the vehicle may be positioned;
wherein the vehicle includes a radar sensor disposed at the vehicle so as to sense exterior of the vehicle;
wherein said radar sensor comprises a plurality of radar transmitters that transmit radio signals and a plurality of receivers that receive radio signals, and wherein the received radio signals are transmitted radio signals that are reflected from an object;
a processor operable to process an output of said receivers;
wherein, with the vehicle at the location, said at least one calibrating transmitter transmits signals that are received by said receivers of said radar sensor; and
wherein, responsive to processing by said processor of the output of said receivers when receiving signals transmitted by said at least one calibrating transmitter, said calibration system determines if said radar sensor is misaligned at the vehicle.

Abstract
A calibration system for calibrating a radar sensing system for a vehicle includes at least one calibrating radar transmitter spaced from a location where the vehicle may be positioned. The vehicle includes a radar sensor disposed at the vehicle so as to sense exterior of the vehicle. The radar sensor includes a plurality of transmitters that transmit radio signals and a plurality of receivers that receive radio signals that are transmitted radio signals reflected from an object. A processor is operable to process an output of the receivers. With the vehicle positioned at the location, the at least one calibrating transmitter transmits signals that are received by the receivers of the radar sensor. Responsive to processing by the processor of the output of the receivers when receiving signals transmitted by the at least one calibrating transmitter, the calibration system determines if the radar sensor is misaligned at the vehicle.

11. A calibration system for calibrating a radar sensing system for a vehicle, said calibration system comprising:
-
a pair of spaced apart calibrating radar transmitters disposed ahead of an end of line test location where the vehicle may be positioned during assembly of the vehicle at a vehicle assembly plant; wherein the calibrating radar transmitters are disposed at opposite sides of the path of travel of the vehicle as it moves through the vehicle assembly plant; wherein the vehicle includes a radar sensor disposed at the vehicle so as to sense exterior of the vehicle; wherein said radar sensor comprises a plurality of radar transmitters that transmit radio signals and a plurality of receivers that receive radio signals, and wherein the received radio signals are transmitted radio signals that are reflected from an object; a processor operable to process an output of said receivers; wherein, with the vehicle at the end of line test location, said receivers of said radar sensor receive signals transmitted by said calibrating transmitters; and wherein, responsive to processing by said processor of the output of said receivers when receiving signals transmitted by said calibrating transmitters, said calibration system determines if said radar sensor is misaligned at the vehicle. - View Dependent Claims (12, 13, 14, 15, 16)

17. A calibration system for calibrating a radar sensing system for a vehicle, said calibration system comprising:
-
a pair of spaced apart calibrating radar transmitters disposed at opposite sides of and ahead of a vehicle positioned at a test location for radar testing; wherein the vehicle includes a radar sensor disposed at the vehicle so as to sense forward of the vehicle; wherein said radar sensor comprises a plurality of radar transmitters that transmit radio signals and a plurality of receivers that receive radio signals, and wherein the received radio signals are transmitted radio signals that are reflected from an object; a processor operable to process an output of said receivers; wherein, with the vehicle at the test location, said receivers of said radar sensor receive signals transmitted by said calibrating transmitters transmit signals; wherein, responsive to processing by said processor of the output of said receivers when receiving signals transmitted by said calibrating transmitters, said calibration system determines if said radar sensor is misaligned at the vehicle; and wherein said processor determines misalignment based on a known position of the vehicle at the test location relative to said calibrating transmitters. - View Dependent Claims (18, 19, 20)
