Vehicular door lock remote control apparatus
First Claim
1. A vehicular door lock remote control apparatus comprising:
- a door sensor for detecting when a door handle on an outer side of a vehicle is touched and outputting a signal representing the detected touch;
vehicle-side transmitting means for transmitting a transmission request signal in response to the signal outputted from said door sensor;
a portable unit for transmitting identification information in response to the transmission request signal from said vehicle-side transmitting means;
vehicle-side receiving means for receiving the identification information transmitted from said portable unit;
control means for determining whether the identification information received by said vehicle-side receiving means matches identification information stored on the vehicle, and unlocking a door of the vehicle based on the determined result;
locked/unlocked state detecting means for detecting a locked/unlocked state of said door;
a timer for starting to measure a predetermined time when said locked/unlocked state detecting means detects when said door has changed from said unlocked state to said locked state; and
inhibiting means for inhibiting the transmission request signal from being transmitted from said vehicle-side transmitting means while said timer is measuring the predetermined time.

Abstract
When a door sensor is touched, a vehicle-mounted unit and a portable unit performs mutual communications for authentication, and the doors are unlocked. When the door sensor is touched without intending to unlock the doors, wasteful consumption of electric energy is avoided which would otherwise result from mutual communications for authentication triggered by a request signal. When the door sensor may possibly be operated not for the purpose of unlocking the doors, e.g., when a CPU detects the doors as being already unlocked from a signal outputted from a door lock knob switch, a request signal is inhibited from being transmitted from the vehicle-mounted unit to the portable unit.
