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.

Enhanced threat assessment

A computer includes a processor and a memory, the memory storing instructions executable by the processor to determine at least one of: a brake threat number of a host vehicle, a brake threat number of a target vehicle, a steering threat number, or an acceleration threat number and to actuate the host vehicle to change at least one of direction or speed based on at least one of the threat numbers. The brake threat number of the host vehicle is based on a predicted lateral distance between the host vehicle and the target vehicle. The brake threat number of the target vehicle is based on a velocity of the target vehicle adjusted by an acceleration of the target vehicle and an actuation time of a brake. 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.

Enhanced collision avoidance

A system includes a computer including a processor and a memory, the memory storing instructions executable by the processor to, upon determining a front threat number exceeds a threat threshold, determine a rear time to collision between a turning host vehicle and a target, and, upon determining that the rear time to collision is below a time threshold, actuate a component based on a rear threat number for the target.

Collision mitigation and avoidance

A computer includes a processor and a memory, the memory storing instructions executable by the processor to, upon determining that a yaw rate for a host vehicle is below a threshold, identify a front corner point of a target, and to suppress threat mitigation when a time to collision between the host vehicle and front corner point of the target exceeds a time threshold.
