  • Patent number: 9381923
    Abstract: An in-vehicle load control system configured to controllably drive one or more loads on a vehicle according to an input signal. The system includes a first electronic control portion configured to perform signal processing based on the input signal, and a second electronic control portion configured to controllably drive the load. A backup signal channel is provided independently of a signal channel through which a signal is transmitted in a multiplex communication portion to input the input signal to the second electronic control portion. The second electronic control portion receives a first control signal via the signal channel in the multiplex communication portion and a second control signal via the backup signal channel, and controllably drives the load by preferentially treating the first control signal when the ignition signal is on and by preferentially treating the second control signal when the ignition signal is off.

  • Publication number: 20150311892
    Abstract: Provided is an electronic control device capable of preventing all of semiconductor relays from being forcibly controlled to be opened by a self-protection shutoff function. An electronic control device controls semiconductor relays provided in a load control unit, which correspond to loads mounted in an automobile. The electronic control device includes a temperature measuring means which measures the ambient temperature of the semiconductor relays. The electronic control device also includes an operation restricting means which, when the temperature measured by the temperature measuring means is higher than or equal to an operation restriction temperature threshold set within an ambient temperature range in which the self-protection shutoff function is not performed in the semiconductor relays, performs control for opening semiconductor relays that correspond to some loads among the loads.
