Abstract: In a target lead-vehicle designating apparatus, a vehicle tracking ECU compares surrounding vehicle information acquired through an inter-vehicle communication unit and vehicle information on preceding vehicles detected by a radar device to designate a target lead-vehicle. The communicated speed of the other vehicles and the detected speed of the preceding vehicles are compared in terms of velocity component in the travel direction of a host vehicle to identify the target lead-vehicle. Accordingly, the target lead-vehicle may be accurately identified even if the target lead-vehicle is close to other vehicles.

Abstract: In a vehicle travel support device 10, an ECU 4 includes an air resistance distribution acquisition unit 41, a target traveling position determination unit 43, and a travel support unit 44. The air resistance distribution acquisition unit 41 acquires air resistance distribution in the left and right directions of a host vehicle. The target traveling position determination unit 43 determines a target traveling position of the host vehicle against a preceding vehicle using the air resistance distribution. The travel support unit 44 performs support to guide the host vehicle to the target traveling position. According to this vehicle travel support device 10, even if an area in which a large aerodynamic effect is obtained by a preceding vehicle deviates in the left and right directions of the host vehicle, the host vehicle can be guided to a position corresponding to the deviation. Because of this, the fuel efficiency can be effectively improved.

Acceleration instruction values for the succeeding four vehicles among the five vehicles are determined as values minimizing predetermined evaluation functions, and the evaluation functions are calculated based on the errors of the distances between the respective vehicles, relative speeds between the respective vehicles and the acceleration instruction values for the respective vehicles.

Abstract: A traffic control system sets a target value related to a travel state based on a correlation between a vehicle travel speed and a traffic volume, and controls multiple vehicles (CS) on a road in accordance with the target value as a common target value.
