Abstract: An in-vehicle device having a function of detecting an anomaly in an in-vehicle system and an interface device having an LED for notifying an occupant of a vehicle of an anomaly state are connected via a communication path for transmitting an alternating current signal. The cathode of the LED is connected to the vehicle body ground, and the anode is connected to the communication line of the communication path via the inductor. When the in-vehicle device detects an anomaly in the in-vehicle system, the in-vehicle device notifies the occupant of the vehicle of the anomaly by applying a direct current drive signal to the communication line to drive the LED.

Abstract: A vehicle communication apparatus includes a reset object portion, a reset portion, a power source determination portion, and a reset execution portion. The reset object portion executes a software in both an on state and an off state of a vehicle power source. The reset portion resets an operation of the software executed by the reset object portion. The power source determination portion determines whether the vehicle power source is in the on state or the off state. The reset execution portion controls the reset portion to reset the operation of the software executed by the reset object portion at a reset time point that is preliminary determined in the off state of the vehicle power source. The reset portion resets the operation of the software when the power source determination portion determines that the vehicle power source is in the off state.

Abstract: An integration circuit charges a capacitor by a charge current corresponding to a current flowing in a detection resistor provided in an electric power supply path extending to a DCM. A comparison circuit outputs a comparison signal, which changes to one of a high level and a low level in accordance with an integration value corresponding to a charge voltage of the capacitor. A discharge switch discharges the capacitor and stops discharge of the capacitor, when the comparison signal is at the high level and the low level, respectively. A control circuit determines an estimation value of electric power supplied from a battery to a DCM based on a count of edges, at which the signal level of the detection signal changes.

Abstract translation: 积分电路通过与设置在延伸到DCM的电力供给路径中的检测电阻中流动的电流相对应的充电电流来对电容器充电。 比较电路根据与电容器的充电电压对应的积分值输出比较信号，该比较信号变为高电平和低电平之一。 当比较信号分别处于高电平和低电平时，放电开关放电电容器并停止电容器的放电。 控制电路基于检测信号的信号电平变化的边缘的计数来确定从电池向DCM提供的电力的估计值。
