Abstract
One or more target areas are identified proximate to a moving vehicle. The vehicle can be maneuvered to a target area selected according to a reinforcement learning reward function.
Claims18
A computer comprising a processor and a memory, the memory storing instructions executable by the processor to:
- identify one or more target areas proximate to a moving vehicle;
- and
- maneuver the moving vehicle to a target area selected according to a reinforcement learning reward function;
- wherein the reward function includes a difference between a current speed and a speed that would result from taking an action affecting movement of the moving vehicle, an amount of time that the moving vehicle has operated without collision in a simulation episode, and a penalty assessed if a lane change results from the action.

A method, comprising:
- identifying one or more target areas proximate to a moving vehicle;
- and
- maneuvering the moving vehicle to a target area selected according to a reinforcement learning reward function;
- wherein the reward function includes a difference between a current speed and a speed that would result from taking an action affecting movement of the moving vehicle, an amount of time that the moving vehicle has operated without collision in a simulation episode, and a penalty assessed if a lane change results from the action.
1 more element
A vehicle, comprising:
- a sensor providing data about an area around the vehicle;
- and
- a computer comprising a processor and a memory, the memory storing instructions executable by the processor to:
- based on data from the sensor, identify one or more target areas proximate to a moving vehicle;
- and
- maneuver the vehicle to a target area selected according to a reinforcement learning reward function;
- wherein the reward function includes a difference between a current speed and a speed that would result from taking an action affecting movement of the moving vehicle, an amount of time that the moving vehicle has operated without collision in a simulation episode, and a penalty assessed if a lane change results from the action.
