A high frequency generating device used in a plasma ignition apparatus according to an embodiment includes a high frequency output unit, an output control unit, a current detecting unit, and an abnormality detecting unit. The high frequency output unit outputs a high frequency. The output control unit shifts a state of the high frequency output unit from a non-output state to an output-ready state of the high frequency. The current detecting unit detects a current that flows through a power-supply path to the high frequency output unit. The abnormality detecting unit detects output abnormality of the high frequency in the non-output state when a value of a current detected by the current detecting unit in the non-output state exceeds a non-output threshold.

High frequency generating device and high frequency generating method used in plasma ignition apparatus

A control device of a plasma ignition apparatus according to an embodiment includes a plug socket, an oscillation unit, and an amplification unit. The plug socket holds an ignition plug, and a high voltage generated by an ignition coil is transmitted to the ignition plug through the plug socket. The oscillation unit oscillates a high frequency. The amplification unit amplifies the high frequency oscillated by the oscillation unit. The oscillation unit is arranged outside of the plug socket and the amplification unit is arranged inside of the plug socket.

Control device of plasma ignition apparatus and plasma ignition apparatus

Provided is a vehicle abnormality detecting device including an abnormality detecting unitA for detecting abnormality on the basis of a state of current supply to a state detecting unit, and a power supply control unitfor switching a state of power supply to the state detecting unitwhen the abnormality was detected by the abnormality detecting unitA, so that power consumption at the time of detecting the abnormality is suppressed to avoid the battery consumption.

Vehicle abnormality detecting device

An input processing circuit is interposed between input terminals and input ports of an MPU. An output processing circuit is interposed between output ports of the MPU and output terminals. The input processing circuit includes switch sections and processing sections. The output processing circuit includes switch sections and processing sections. A switch control section switches the switch sections based on switch information stored in a switch information storage section to switch a connection relationship between the input terminals and the input ports, processing for an input signal, a connection relationship between the output ports and the output terminals, and processing for an output signal.
