Abstract: A platoon travel system includes an extraction portion, an arrangement order determination portion, a schedule notification portion, a contribution degree calculation portion, and a charge portion. The contribution degree calculation portion calculates a contribution degree for each of the plurality of target vehicles using loss-gain information. The contribution degree is calculated with respect to a benefit of all of the plurality of target vehicles obtained by performing the platoon travel. The loss-gain information reflects the benefit obtained when the plurality of target vehicles participate in the platoon travel. The charge portion determines a charge amount for each of the plurality of target vehicles based on the contribution degree calculated by the contribution degree calculation portion when the platoon travel is performed based on the platoon information. The charge amount is determined for each of the plurality of target vehicles to fairly obtain an advantage.

Abstract: A keyless entry device can accurately judge or determine whether a portable device exists inside or outside a vehicle. A vehicle-side controller includes a memory that stores an inside data group having a plurality of intensity information of a request signal transmitted from the plurality of transmitting antennas when the portable device is located along an inside of a vehicle. Also included is an outside data group having a plurality of intensity information of a request signal transmitted from the plurality of transmitting antennas when the portable device is located along an outside of the vehicle. The vehicle-side controller judges an area where the portable device exists from the intensity information of the request signal received from the portable device. The controller instantly judges the inside or the outside of the vehicle, when the portable device exists in an area apart from a boundary.
