INTERACTION BETWEEN HOST VEHICLE AND TARGET VEHICLE

A computer includes a processor and a memory, and the memory stores instructions executable by the processor to determine a host kinematic state of a host vehicle, determine a target kinematic state of a target vehicle, determine a quantity characterizing an intersection of a host path of the host vehicle and a target path of the target vehicle, and actuate a component of the host vehicle based on the quantity. The host path is based on the host kinematic state, and the target path is based on the target kinematic state. At least one of the host path or the target path is curved.
