Abstract
A first vehicle velocity target is determined based on a velocity of a proximate second vehicle and at least one of a curvature of a road, a gradient of the road, a bank angle of the road, visibility, and a coefficient of friction on a surface of the road.
Claims14
A method, comprising:
- in a first vehicle, assigning respective weights to each of a plurality of second vehicles according to a respective location relative to the first vehicle of each second vehicle;
- identifying one of the second vehicles as an immediately forward vehicle, and increasing the weight assigned to the immediately forward vehicle based on at least one of the curvature of the road, the gradient of the road, the bank angle of the road, visibility, or a coefficient of friction on the surface of the road;
- and controlling a first vehicle velocity based on respective velocities of the plurality of second vehicles and at least one of a curvature of a road, a gradient of the road, a bank angle of the road, visibility, or a coefficient of friction on a surface of the road, including adjusting a target speed of the first vehicle according to the respective velocities of the second vehicles, each adjusted by the respective weight assigned to each respective second vehicle.
A computer comprising a processor and a memory, the memory storing instructions executable by the processor for:
- in a first vehicle, assigning respective weights to each of a plurality of second vehicles according to a respective location relative to the first vehicle of each second vehicle;
- identifying one of the second vehicles as an immediately forward vehicle, and increasing the weight assigned to the immediately forward vehicle based on at least one of the curvature of the road, the gradient of the road, the bank angle of the road, visibility, or a coefficient of friction on the surface of the road;
- and controlling a first vehicle velocity based on respective velocities of the plurality second vehicles and at least one of a curvature of a road, a gradient of the road, a bank angle of the road, visibility, or a coefficient of friction on a surface of the road, including adjusting a target speed of the first vehicle according to the respective velocities of the second vehicles, each adjusted by the respective weight assigned to each respective second vehicle.
