<p>PROBLEM TO BE SOLVED: To provide a control device that suppresses an increase in the number of core wires of a wire harness connecting a plurality of sensors and the control device together and besides, performs an accurate control operation by correctly receiving a signal from each of the sensors.SOLUTION: The control device includes a housing (104) that houses a control circuit. The control circuit has a plurality of outlets (140, 142, and 144) of ground currents. The housing is configured in such a manner that the plurality of outlets of ground currents from the control circuit are individually and electrically connected to the housing, and are electrically connected directly or indirectly to a ground of a power supply at predetermined positions (106a and 106b) of the housing. A ground of a sensor is connected to a first predetermined point (158) of the housing over a lead wire. The first predetermined point is located upstream from a position at which the sum total of the ground currents exceeds a predetermined value, along a path of the ground currents leading to the ground of the power supply.</p> |
