Abstract: A computer includes a processor and a memory, the memory including instructions executable by the processor to predict a collision time between a corner point of a host vehicle and a target vehicle, predict a reach time for the corner point of the host vehicle to reach the target vehicle based on a predicted relative heading angle between the host vehicle and the target vehicle, and determine a threat number based on the lower of the collision time and the reach time.

Abstract: A first distance is determined between a location of a host vehicle and a received location of a remote vehicle, the remote vehicle being forward of the host vehicle. A second distance is determined between a target vehicle and the host vehicle. A time to reach is predicted between the target vehicle and the remote vehicle based on the first distance and the second distance. A brake of the host vehicle is pre-charged when the predicted time to reach is below a time threshold. Pre-charging of the brake of the host vehicle is suppressed when the predicted time to reach is above the time threshold.

The steering threat number is a lateral acceleration being a predicted lateral distance adjusted by an actuation time of a steering component. The acceleration threat number is based on a predicted lateral offset adjusted by a predicted heading angle of the host vehicle.
