Abstract: An electronic control device according to an embodiment of the present invention includes an arithmetic device such as a microcomputer having a watchdog timer circuit, and a runaway monitoring circuit which monitors the arithmetic device for an operational failure by receiving a pulse output from the arithmetic device, in which the watchdog timer circuit or the runaway monitoring circuit detects occurrence of a failure of the arithmetic device according to the state (high level or low level) of an indication signal (wakeup signal) which shows the operational state of the arithmetic device.

Abstract: A vehicular electronic control apparatus includes a vehicle control section and a unit control section. The vehicle control section controls a function dependent on a vehicle equipment. The unit control section that controls a function of a unit provided in a vehicle. The vehicle control section and the unit control section are disposed in independent hardwares and software platforms, respectively.

Abstract: A charging control apparatus is adapted to control an alternator which is operable to generate a voltage to charge a battery which is operable to supply the voltage to an electric component. An interface is connected to the alternator, the battery, and the electric component and operable to input and output a signal therebetween. A microcomputer is connected to the inter face and operable to execute a gradual change process in which a generating voltage of the alternator is gradually changed to a target generating voltage of the alternator and a sudden change process in which the generating voltage is suddenly changed to the target generating voltage. The microcomputer is operable to detect a using status of the electric component based on the signal. The microcomputer is operable to judge whether the gradual change process is required or the sudden change process is required based on the detected using status.

Abstract: A power management device comprises a start management control unit having a starter hold control function for actuating a starter motor and holding the actuation based on an operating signal from a button switch, a first terminating unit for terminating cranking hold when receiving a starter stop instruction signal sent from an engine control device when it is determined that an engine reached a complete explosion, a second terminating unit for terminating cranking hold when it is determined that the engine reached a complete explosion based on an engine revolution signal sent from the engine control device, and a forced terminating unit for forcefully terminating cranking hold when cranking hold cannot be terminated by those terminating units.

Abstract: A vehicle control section is operable to control the vehicle based on information on a degree of risk in a risky point through which the vehicle is predicted to drive.
