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.
Claims19
A system, comprising a computer including 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, the collision time being a predicted time at which the corner point of the host vehicle attains a same position as the target vehicle;
- predict a relative heading angle between the host vehicle and the target vehicle based on the collision time;
- predict a reach time for the corner point of the host vehicle based on the predicted relative heading angle, the reach time being a predicted time at which the corner point of the host vehicle reaches a longitudinal distance threshold;
- determine a threat number based on the lower of the collision time and the reach time;
- and
- actuate a vehicle component based on the threat number.
A method, comprising:
- predicting a collision time between a corner point of a host vehicle and a target vehicle, the collision time being a predicted time at which the corner point of the host vehicle attains a same position as the target vehicle;
- predicting a relative heading angle between the host vehicle and the target vehicle based on the collision time;
- predicting a reach time for the corner point of the host vehicle based on the predicted relative heading angle, the reach time being a predicted time at which the corner point of the host vehicle reaches a longitudinal distance threshold;
- determining a threat number based on the lower of the collision time and the reach time;
- and
- actuating a vehicle component based on the threat number.
A system, comprising:
- a host vehicle including a brake;
- means for predicting a collision time between a corner point of the host vehicle and a target vehicle, the collision time being a predicted time at which the corner point of the host vehicle attains a same position as the target vehicle;
- means for predicting a relative heading angle between the host vehicle and the target vehicle based on the collision time;
- means for predicting a reach time for the corner point of the host vehicle based on the predicted relative heading angle, the reach time being a predicted time at which the corner point of the host vehicle reaches a longitudinal distance threshold;
- means for determining a threat number based on the lower of the collision time and the reach time;
- and
- means for actuating the brake based on the threat number.
