Door control system and receiver
First Claim
1. A door control system comprising:
- a transmitter including a button operated to issue a door lock demand, a button operated to issue a door unlock demand and a transmission circuit for sending out selected one of a lock demand signal and an unlock demand signal in response to the operation of said buttons;
means for driving the doors of an automotive vehicle to open or close;
means for controlling the lock/unlock operation of the doors of the vehicle; and
a receiver for receiving a selected one of said lock demand signal and said unlock demand signal from said transmitter and determining whether said received one of said lock demand signal and said unlock demand signal is in first mode or second mode, said receiver outputting a signal for causing said lock/unlock control means to perform selected one of the lock and unlock operation, respectively, of the doors in the case where said determination shows that said selected one of said lock demand signal and said unlock demand signal is in said first mode, said receiver outputting a signal for causing said door open/close drive means to perform selected one of the operations for opening and closing the doors, respectively, in the case where said determination shows that said selected one of said lock demand signal and said unlock demand signal is in said second mode.

Abstract
A system for remotely controlling the doors of an automotive vehicle with a reduced number of transmitters to be held and a reduced number of buttons of the transmitters is disclosed. The transmitter has a lock button and an unlock button. Upon depression of the lock button or the unlock button, a corresponding demand signal is transmitted repeatedly. The demand signal includes an ID code, a button code and a time code. The button code indicates the identification of the lock button or the unlock button. The time code indicates whether a button has been kept depressed for at least a predetermined length of time or the number of times the button is depressed. The receiver controls the door lock/unlock operation and the door open/close operation based on the button code and the time code. The time code can be replaced with a number-of-times code indicating the number of times a button is depressed.

2. A receiver for a door control system, comprising:
-
a receiving unit for receiving a lock demand signal;
a determining unit for determining whether said received lock demand signal is in a first mode or a second mode; and
a control unit for outputting a signal for causing the lock control means to lock the doors in the case where said lock demand signal is in said first mode, and outputting a signal for causing the door open/close drive means to perform the operation for closing the doors in the case where said lock demand signal is in said second mode, said control unit thereafter outputting a signal for causing said lock control means to lock the doors. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)
