Abstract
Autonomous driving systems and methods include a controller of a first vehicle configured to detect an operating state of a second vehicle proximate the first vehicle, and to predict, based on the operating state of the second vehicle, a potential behavior for the second vehicle that optimizes a cost function from the perspective of the second vehicle. The controller then controls the first vehicle to avoid a collision with the second vehicle assuming the second vehicle operates according to the potential behavior.
Claims20
An autonomous driving system of a first vehicle comprising:
- a controller configured to detect an operating state of a second vehicle traveling proximate the first vehicle;
- predict, at the first vehicle, a first potential behavior of the second vehicle based on the operating state of the second vehicle and from a perspective of the second vehicle, wherein the prediction comprises determining a plurality of characteristics of a cost function from a point of view of the second vehicle and optimizing the cost function from the point of view of the second vehicle, wherein the plurality of characteristics pertain to motion of the second vehicle;
- and control the first vehicle to avoid a collision with the second vehicle assuming the second vehicle operates according to the first potential behavior.
A controller for an autonomous driving system of a first vehicle, the controller comprising:
- at least one processor;
- and a memory storing instructions that, upon execution by the at least one processor, causes the at least one processor to;
- detect an operating state of a second vehicle traveling proximate the first vehicle;
- predict, at the first vehicle, a first potential behavior of the second vehicle based on the operating state of the second vehicle and from a perspective of the second vehicle, wherein the prediction comprises determining a plurality of characteristics of a cost function from a point of view of the second vehicle and optimizing the cost function from the point of view of the second vehicle, wherein the plurality of characteristics pertain to motion of the second vehicle;
- and control the first vehicle to avoid a collision with the second vehicle assuming the second vehicle operates according to the first potential behavior.
A method comprising:
- by one or more processors of a first vehicle:
- detecting an operating state of a second vehicle traveling proximate the first vehicle;
- predicting, at the first vehicle, a first potential behavior of the second vehicle based on the operating state of the second vehicle and from a perspective of the second vehicle, wherein the prediction comprises determining a plurality of characteristics of a cost function from a point of view of the second vehicle and optimizing the cost function from the point of view of the second vehicle, wherein the plurality of characteristics pertain to motion of the second vehicle;
- and controlling the first vehicle to avoid a collision with the second vehicle assuming the second vehicle operates according to the potential behavior.
