Abstract: A power supply control system includes a plurality of electronic control units, a monitoring device, a power source line coupled with each of the electronic control units for supplying an operating voltage to each of the electronic control units, and a power source switch disposed on the power source line. The monitoring device calculates a deactivating threshold value based on an assigned threshold value of each of the electronic control units set in accordance with an operating state of each of the electronic control units. The monitoring device deactivates the power source switch so as to stop the supply of the operating voltage to all of the electronic control units when an electric current value of the power source line is greater than the deactivating threshold value.

Abstract: An on-vehicle electronic device control system includes a base-device-layer on which base-inputting-devices and base-driven-devices are disposed and plural control layers on which plural control units are disposed. Each of the control units has a lower-to-higher-layer-data-input-portion for inputting data from a lower layer and a higher-to-lower-layer-data-output-portion for outputting control-command-data to a lower layer. At least one of the control units disposed on one of the control layers has a higher-to-lower-data-input-portion for inputting data from a higher layer.

Abstract: A vehicle interior environment control system includes a plurality of environment adjustment sections adapted to operate in cooperation with each other so as to control optimization of an environment of a vehicle interior, a grading parameter setting section for setting a grading parameter indicative of a capacity grade of each of the environment adjustment sections in one-to-one relation to the environment adjustment sections, an environmental luxury degree setting section for adjustably setting an environmental luxury degree desired by a user for a total environmental adjustment state of the vehicle interior, and an integrated control section. The integrated control section controls the cooperation between the environment adjustment sections, such that as the environmental luxury degree set by the environmental luxury degree setting section becomes higher, the environment adjustment section with the higher capacity grade indicated by the grading parameter is preferentially operated.

Abstract: A flexible wiring system for an electronic system includes a basic control circuit for controlling specific control circuits to obtain data from a sensor, a communication bus connected with the basic control circuit and the specific control circuits, and an intermediate distributing unit. The intermediate distributing unit includes plural first side connectors connectable with the basic control circuit and the specific control circuits, plural second side connectors connectable with sensors and actuators. The basic control circuit communicates signals with the specific control circuits via the communication bus so that the specific control circuits can control corresponding actuators according to the data obtained from corresponding sensors via the intermediate distributing unit.

Abstract: A flexible wiring system for an electronic system includes an intermediate distributing unit and a changeover control unit. The intermediate distributing unit includes first side connectors connectable with an input side and an output side of a basic control circuit, second side connectors connectable with inputting devices such as various sensors and outputting devices such as various actuators and a changeover mechanism disposed between a set of the first side connectors and a set of the second side connectors. The changeover control unit controls the changeover mechanism to change connection of the set of first side connectors with the set of second side connectors according to a specific device to be connected with the set of second side connectors.
