Control system for electric devices installed in automotive slide door
First Claim
1. A control system for use in a motor vehicle which includes a vehicle body and a slide door, comprising:
- a body-side control circuit installed in said vehicle body and including;
a door-side control circuit installed in said slide door;
two coil elements respectively mounted to said vehicle body and said slide door and respectively connected to said body-side and door-side control circuits, said two coil elements coming close to each other when said slide door comes to its closed position relative to a door opening formed in said vehicle body; and
means for providing a radio or wireless communication between the body-side and door-side control circuits by practically using an electromagnetic induction generated between the two coil elements.

Abstract
A control system is provided for controlling electric devices installed in a slide door which moves relative to a door opening formed in a vehicle body. The control system comprises a first electric device for detecting a door-closed condition wherein the slide door is at its fully closed position relative to the door opening and a second electric device for positively suppressing operation of the electric devices until the time when the first electric device detects the door-closed condition. For achieving communication between the first and second electric devices, an electromagnetic induction phenomenon is practically used.

6. In a motor vehicle including a vehicle body, a slide door, electric devices mounted in said slide door, an electric door closure unit for shifting the slide door from a half-latched position to a full-latched position when actuated, a first group of control switches mounted in said vehicle body, and a second group of control switches mounted in said slide door,
a control system for controlling the door-mounted electric devices in accordance with operation of said first and second group of switches, comprising: -
a body-side control circuit installed in said vehicle body and electrically connected to said first group of control switches; a door-side control circuit installed in said slide door and electrically connected to said second group of control switches, the door-mounted electric devices and said electric door closure unit; and a connector arranged between the vehicle body and the slide door, which comprises a pin type connection section through which an electric power supply is achieved from the body-side control circuit to said door-side control circuit when the slide door comes to a half-latched position under closing movement thereof, and a coil element section through which radio connection is achieved between said body-side and door-side control circuits so that the door-mounted electric devices are controlled in accordance with operation of the first and second group of control switches, wherein said door-side control circuit suppresses the operation of said coil element section of the connector until the electric door closure unit shifts the slide door from the half-latched position to the full-latched position. - View Dependent Claims (7, 8, 9)
