Vehicle Pre-Crash Safety Systems (Equipment Packages*)

This equipment package monitors the vehicle's local environment, determines collision probability, and deploys a pre-crash safety system when a crash is imminent. It includes on-board communications equipment and sensors to determine the proximity and closing rates of neighboring vehicles or other roadway obstacles. These detection systems are supplemented by additional sensors that monitor existing weather and roadway conditions and roadway geometry. The equipment package assimilates this information and determines the probability of a collision with the other vehicle or obstacle. If the collision probability is high, it deploys a pre-crash safety system either to avoid the accident or to reduce the accident severity.

Functionality:

    Functional Requirements*:
    1. The vehicle shall monitor the area around the vehicle to determine the proximity of other objects to the vehicle.
    2. The vehicle shall send and receive current vehicle location and trajectory information and use this information to determine the proximity of other vehicles and closing rates.
    3. The vehicle shall evaluate the likelihood of a collision between two vehicles or a vehicle and a stationary object, based on the proximity of other objects to the vehicle, conditions of the roadway and environment, and the current speed and direction of the vehicle.
    4. The vehicle shall deploy a pre-crash safety system either to avoid the accident or to reduce the accident severity, once it has determined the probability of a collision with the other vehicle or obstacle to be high.
