Sensor field selection
First Claim
1. A method for controlling a vehicle having an autonomous operation mode, the method comprising:
- controlling, by a processor, operation of the vehicle based on a first control strategy;
identifying a sensor field based on a field of view of one or more sensors of the vehicle;
receiving sensor data from selected ones of the one or more sensors;
detecting a moving object in the roadway and a location of the object in the sensor field based on the received sensor data;
identifying a change in sensor perception of the one or more sensors based on the location of the object, the change in the sensor perception including a decrease in an ability to detect objects within the sensor field;
determining, based on the change, a second control strategy for increasing the ability to detect objects within the sensor field; and
responsive to identifying the change, maneuvering, by the processor, the vehicle in the autonomous mode so that the vehicle falls behind the object according to the second control strategy in order to increase the ability to detect objects within the sensor field.

Abstract
Aspects of the present disclosure relate generally to safe and effective use of autonomous vehicles. More specifically, an autonomous vehicle is able to detect objects in its surroundings which are within the sensor fields. In response to detecting objects, the computer may adjust the autonomous vehicle'"'"'s speed or change direction. In some examples, however, the sensor fields may be changed or become less reliable based on objects or other features in the vehicle'"'"'s surroundings. As a result, the vehicle'"'"'s computer may calculate the size and shape of the area of sensor diminution and a new sensor field based on this area of diminution. In response to identifying the area of sensor diminution or the new sensor field, the vehicle'"'"'s computer may change the control strategies of the vehicle.
