Abstract
An autonomous vehicle and a system and method of operating the autonomous vehicle. The system includes a sensor and a processor. The processor determines an effective observation area of the sensor, the effective observation area being affected by an extrinsic condition. The processor determines an available time for performing a lane change based on the effective observation area and performs the lane change based on the available time.
Claims17
A method of operating an autonomous vehicle, comprising:
- operating a sensor to obtain a detection over an effective observation area, wherein the sensor is operated at a first effective range;
- reducing the first effective range to a second effective range less than the first effective range when no detection is made in the observation area by the sensor within a selected time interval;
- determining an available time for performing a lane change based on the second effective range;
- and
- performing the lane change based on the available time.
A system for operating an autonomous vehicle, comprising:
- a sensor for obtaining a detection over an effective observation area, the sensor operating at a first effective range;
- and
- a processor configured to:
- reduce the first effective range to a second effective range less than the first effective range when no detection is made in the observation area by the sensor within a selected time interval;
- determine an available time for performing a lane change based on the effective observation area;
- and
- perform the lane change based on the available time.
