Vehicle Longitudinal Control (Equipment Packages*)
This equipment package provides longitudinal control of a vehicle to allow "feet off" driving, automating the function of speed control, acceleration, and braking to maintain safe following distances. It includes on-board systems that detect obstacles or vehicles in the longitudinal path of the vehicle. This sensor information is processed on board the vehicle, and appropriate control actions (acceleration, braking, or maintaining speed) are initiated using accelerator and/or brake actuators.Included In:

Functional Requirements*:
- The vehicle shall monitor the area behind and in front of the vehicle to determine the proximity of other objects to the vehicle.
- 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 and the current speed and direction of the vehicle.
- The vehicle shall provide position warnings to the driver when an object gets close enough to the vehicle to become a hazard if no action is taken by the driver.
- The vehicle shall provide an interface through which a vehicle driver can initiate, monitor and terminate automatic control of the vehicle.
- The vehicle shall send appropriate control actions (acceleration, braking, or maintaining speed) to the vehicle's accelerator and/or brake actuators.
- The vehicle shall present information to the driver in audible or visual forms without impairing the driver's ability to control the vehicle in a safe manner.
