Abstract
A method and system for operating an autonomous vehicle. The method includes determining, at an electronic processor, a limit for a forward velocity setpoint of the autonomous vehicle based a range of a forward facing sensor and detecting whether a preceding vehicle is in a field of view of the forward facing sensor. The method includes determining a speed of the preceding vehicle, and when the preceding vehicle is in the field of view of the autonomous vehicle, adjusting the limit based on the speed of the preceding vehicle.
Claims17
A method of operating an autonomous vehicle, the method comprising:
- determining, at an electronic processor, a limit for a forward velocity setpoint of the autonomous vehicle based a range of a forward facing sensor;
- determining a stopping distance of the autonomous vehicle;
- detecting whether a preceding vehicle is in a field of view of the forward facing sensor;
- determining a speed of the preceding vehicle;
- setting the limit to a value based on the stopping distance of the autonomous vehicle and the range of the forward facing sensor;
- and
- when the preceding vehicle is in the field of view of the autonomous vehicle adjusting the limit based on the speed of the preceding vehicle.
An adaptive speed control system for an autonomous vehicle, the system comprising:
- a forward facing sensor;
- and
- an electronic processor communicatively connected to the forward facing sensor, the electronic processor configured to
- determine a limit for a forward velocity setpoint of the autonomous vehicle based on a range of a forward facing sensor;
- determine whether a preceding vehicle is in a field of view of the forward facing sensor;
- determine a speed of the preceding vehicle;
- and
- when the preceding vehicle is in the field of view of the autonomous vehicle, adjust the limit based on the speed of the preceding vehicle, the limit being no longer based on the range of the forward facing sensor.
