Abstract
A calibration system and method for calibrating a sensor installed on a vehicle includes a target proximate to a travel-path of a vehicle, a digital-map, the digital-map configured to indicate a coordinate of the target, a sensor mounted on the vehicle, said sensor configured to detect the target, and a controller in communication with the digital-map and the sensor. The controller or the method is configured to, in accordance with a determination that the target is detected by the sensor, perform a calibration of the sensor. By using targets documented on a digital-map to perform calibration, the vehicle does not need to be taken to a specialized facility in order to be calibrated.
Claims22
A calibration system for calibrating a sensor installed on a vehicle, said system comprising:
- a target proximate to a travel-path of a vehicle;
- a digital-map, the digital-map configured to indicate a coordinate of the target;
- a sensor mounted on the vehicle, said sensor configured to detect the target;
- a controller in communication with the digital-map and the sensor, said controller configure to, in accordance with a determination that the target is detected by the sensor, perform a calibration of the sensor.
A controller for calibrating a sensor on a vehicle, said controller comprising:
- an input configured to receive a signal from a sensor;
- a processor configured to determine a coordinate of a target on a digital-map, determine when the vehicle is proximate to the target in accordance with the coordinate, and perform a calibration of the sensor in accordance with the signal and the coordinate in response to a determination that the target is detected by the sensor.
A method of calibrating a sensor mounted on a vehicle, said method comprising:
- receiving from the sensor an indication of the sensor detecting a target;
- and
- performing, by a controller in communication with a sensor mounted on a vehicle and in accordance with a determination that the sensor detected the target, a calibration of the sensor.
A system, comprising:
- a target, the target positioned in space proximate a travel-path of a vehicle;
- a digital map, the digital map indicating the travel-path and an indicated-coordinate of the target positioned in space proximate the travel path;
- a sensor, mounted on the vehicle, the sensor detecting a detected-coordinate of the target positioned in space;
- and
- a processor, the processor in communication with the sensor, the processor determining a difference between the indicated-coordinate and the detected-coordinate, and in accordance with a determination that the difference is greater than a predetermined-threshold, performing a calibration of the sensor.
A system, comprising:
- a vehicle;
- a map, the map indicating a travel-path of the vehicle and at least one coordinate of a target positioned in space proximate the travel path;
- a sensor mounted on the vehicle, the sensor detecting at least one coordinate of the target positioned in space proximate the travel path as the vehicle travels along the travel path;
- and
- a processor, the processor in communication with the sensor, the processor determining a difference between the at least one coordinate indicated by the map and the at least one coordinate detected by the sensor, and
- in accordance with a determination that the difference is greater than a predetermined-threshold, performing a calibration of the sensor.
