Abstract

A vehicle equipment control system locks vehicle doors by any one of auto-lock and trigger lock systems. In the auto-lock system, a wide communication area is set that covers an entire vehicle compartment is set. In the trigger lock system, a narrow communication area is set that disables the communication with a portable unit carried by a user near a vehicle. When no response signal is received from the portable unit in the respective communication areas, the respective vehicle doors are locked. Accordingly, even when any one of the auto-lock and trigger lock systems is used, the portable unit is prevented from being left in the compartment, and the respective vehicle doors can be locked.
