Embodiment Construction

[0025] Embodiments of the present invention will be described with reference to the drawings. In addition, in the following description, it is assumed that the control device of the present invention is mounted on a vehicle, but the embodiments of the present invention are not limited thereto, and it is of course also applicable to the control of other machinery and equipment other than vehicles. There is no doubt about it.

[0026] figure 1 It is a basic configuration diagram of the control device according to the embodiment of the present invention. A substrate 1 of an electronic control unit (hereinafter referred to as "ECU") corresponding to a control device is provided with an internal ground (hereinafter referred to as "GND") 2 at its peripheral portion. The internal GND 2 of the ECU board 1 is directly connected to a frame (casing) 10 housing the ECU board 1 therein via a contact 9 made of a conductive material such as metal. The housing 10 is made of a conductive ma...

Abstract

Provided is a control device for processing the electric signals from a sensor used for detecting physical value and outputting the electric signals for controlling the controlled objects. The control device comprises: an internal grounding part electrically connected with the sensor and the controlled objects, a power supply circuit that provides electric power for driving the sensor and is electrically connected with the internal grounding part, and an arithmetic unit which operates the electric signals from the sensor and is electrically connected with the internal grounding part.

Description

technical field [0001] The present invention relates to a control device, in particular to a control device that processes electrical signals sent by sensors that detect physical values ​​and outputs electrical signals that control objects to be controlled. Background technique [0002] Generally, in order to prevent a control object from malfunctioning, a control device requires a highly accurate sensor output (physical value). The control device is usually used in such a situation: make the sensor output a differential output from the ground (GND), perform A / D conversion on the differential output, perform arithmetic processing on the digital value after the A / D conversion, and control the control object . [0003] However, in an environment where the influence of noise from vehicles or the like is strong, noise enters GND and the like to cause fluctuations in its potential, and the differential output based on the sensor output may become an output with poor accuracy inc...
