Vehicular remote control system
First Claim
1. A vehicular remote control system comprising:
- a mobile unit carried by a driver and having a plurality of transmission antennas; and
a vehicle unit mounted on a vehicle, wherein said mobile unit sequentially receives signals transmitted from at least one of the transmission antennas to measure the reception intensities of the individual response signals, and then transmits the information on those reception intensities all at once to said vehicle unit, and wherein said vehicle unit locates said mobile unit on the basis of the reception intensity information transmitted from said mobile unit, and executes an arbitrary processing action according to the location of said mobile unit.

Abstract
To acquire a more satisfactory operation feel by making a time lag as short as possible from the instant when push button switches on the side of a vehicle are pushed to the instant when a door is actually locked/unlocked or when a trunk is actually opened. A vehicular remote control system includes a mobile unit carried by a driver and a vehicle unit mounted on a vehicle. The mobile unit sequentially receives signals transmitted from an n-number of transmission antennas of the vehicle unit to measure the reception intensities of the individual response signals, and then transmits those n-number of pieces of reception intensity information all at once to the vehicle unit. The vehicle unit locates the mobile unit on the basis of the n-number of pieces of reception intensity information. If the time period necessary for each reception intensity measurement is designated by Ta and if the time period necessary for the notification of the measurement result is designated by Tb, the time lag can be reduced by the difference between {n×(Ta+Tb)} and (n×Ta+Tb).
