In embodiments of this application, the first VIU controls the plurality of automobile parts.

Systems and methods are provided for enhancing diagnosis of control logic by automatically triggering latent or quiescent diagnostic logic in response to a CAN bus signal and without requiring a software update of the control logic. The diagnostic logic may be triggered to provide an increase in the frequency of CAN messages that are generated. The diagnostic logic may be further triggered to provide a generation of additional CAN messages reporting operation signals beyond those that are normally generated. The diagnostic logic may be further triggered to provide higher priority to selected CAN messages reporting operation signals. The diagnostic logic may be still further triggered to one or more of increase the frequency of selected CAN report messages, generate additional CAN messages reporting operation signals beyond those that are normally generated, and/or provide higher priority to selected CAN messages reporting operation signals, each without requiring a software update.

A power supply circuit for supplying power to an electric load of a vehicle includes a relay and a relay control circuit. The relay is configure to be turned on when enabling the supply of power to the electric load and configured to be turned off when interrupting the supply of power to the electric load. The relay control circuit is configured to turn on the relay when an ignition of the vehicle is on regardless of a state of an operation part that is to be operated by a driver to operate the electric load.

The invention relates to a method for adapting a wiring harness (1) for a motor-driven land vehicle in order to enable, without cut or splice, connecting said wiring harness to a computer system that is configured to be temporarily and removably mounted onboard a motor-driven land vehicle, said wiring harness comprising a first connector (4), which is provided with at least one socket (5), in which a plug is removably housed (3), said plug being arranged at one end of an electrical wire (2), and a second connector (7) which is provided with at least one pin (6), said second connector (7) being configured to be connected to an electronic control unit of the vehicle. The invention further relates to a wiring harness adapted according to such a method as well as to a motor-driven land vehicle provided with such a wiring harness.

An on-board communication system includes a plurality of function units mounted on a vehicle and performing predetermined information communication, a plurality of communication units disposed respectively corresponding to the plurality of function units, and a plurality of wired transfer paths connecting the plurality of communication units to one another. Each of the plurality of communication units transmits and receives signals in a radio frequency band to and from the other communication units via the wired transfer paths, the signals being modulated and including communication information to be transferred among the function units.

A slave communication apparatus including a clock recovering section that recovers a clock signal from a transmission signal having a first signal value when the clock is a first level, a second signal value when the clock is a second level and data has a first data value, and a third signal value between the first and second signal values when the clock is the second level and the data has a second data value; and a data recovering section that recovers the data, wherein the data recovering section sets the data threshold value to be a first setting value between the second and third signal values in response to the recovered data having the second data value, and sets the data threshold value to be a second setting value between the first and third signal values in response to the recovered data having the first data value.

Systems and methods for supplying electrical power between two electric energy storage devices are disclosed. In one example, an electric isolation switch is held open after engine starting until a voltage of a first electric energy storage device and a voltage of a second electric energy storage device are within a threshold voltage of at least one predetermined voltage level.

In an in-vehicle network, a master device and a plurality of slave devices communicate with each other. A plurality of semiconductor relays for supplying power to the corresponding slave devices is provided for each of the plurality of slave devices in the master device. IDs corresponding to the plurality of semiconductor relays are stored in a flash ROM of the master device. The master device transmits the corresponding ID each time the semiconductor relays are turned on by sequentially turning on the semiconductor relays. The plurality of slave devices set the ID received after power supply as its own ID.

Reliability and responsiveness in vehicles are becoming more important as semi-automation and automation are becoming more prevalent. A redundant Ethernet network system is provided within a vehicle and includes a first node connected to a first sensor and a second node connected to a second sensor. A first Ethernet cable is connected between the first node and the second node, a second Ethernet cable is connected between the first node and an electronic control unit (ECU), and a third Ethernet cable connected between the second node and the ECU. Data from the first sensor and the second sensor is transmitted across the Ethernet network to reach the ECU. Data from these sensors is also compared and processed locally at the first node and the second node to improve reliability and to reduce processing load on the ECU.

An adjustable exterior mirror on a vehicle, or another kind of settable unit for installation in or on the vehicle, signals a sensor signal via the current through the current conductors for the supply current of a motor, heating or other function holder in the vision unit. In response to external switching-on of a supply voltage between the current conductors, for example from the vehicle, an aspect of the current is sensor-dependently controlled from the settable unit. In the vehicle, the aspect of the current through at least one of the current conductors is measured during a delay time interval after switching-on of the supply voltage to read out the sensor result.
