The device uses a constant vehicle speed zone determined between the engine-braking-start threshold value and the acceleration-control-completion threshold value. When a compensated-evaluation-index value KdB_c of a vehicle distance between the own vehicle and a preceding vehicle is within the constant vehicle speed zone, the device drives the own vehicle at a constant speed. This control suppresses fuel consumption because of decreasing an acceleration and deceleration frequency of the own vehicle. Decreasing the deceleration frequency makes it possible to provide good vehicle following because less frequent acceleration is needed for following the preceding vehicle even if another vehicle cuts in between the own vehicle and the preceding vehicle or the preceding vehicle accelerates after decelerating.

A method is provided for rapidly identifying potential collision threats between communicating vehicles in a vehicle communication network for actuating a vehicle control action to mitigate potential collisions between the communicating vehicles. Vehicle boundaries and trajectory path boundaries are constructed for the communicating vehicles for efficiently identifying a potential collision. Prioritized assessments are performed to determine which respective boundaries intersect one another. Based on whether respective boundaries that intersect one another will determine if a control vehicle control action is initiated and which control action is imitated. Once the intersecting boundaries are identified, a location of the potential collision can be rapidly identified by a technique that subdivides and regenerates the intersecting trajectory path boundaries of the vehicles. A distance to the potential collision may be determined that is used to further enhance the control action taken for mitigating the potential collision.
