Abstract

PURPOSE:To perform reliable self-diagnosis of electric accessories before reduction in a source voltage during the starting, by providing a delay means which causes delay of the starting of an engine by a given time required for self- diagnosis of electric accessories during the starting of an engine. CONSTITUTION:With an ignition switch 2 controlled during the starting of the engine of a car, contacts 5 and 6 are brought into contact with each other. In which case, a current is fed to an electric accessories 8, a contact 7a of a starter relay 7 is closed, and a current is fed to a starter motor 9 to start an engine. A timer 11 is turned ON through energization, and is turned OFF after a time being long enough for the electric accessories 8 to allow self- diagnosis has lapsed. This enables reliable self-diagnosis of the electric accessories before a source voltage is decreased during the starting.

(Problem to be solved by the invention) By the way, in recent vehicles, electrical components are self-diagnosed within a short period of time when the engine is started, when the driver's attention is focused on the gauges on the instrument panel. Self-diagnosis is performed to check the presence or absence of output from each sensor of the engine control device, check the operation of the automatic speed control device as a system, and check for disconnection of lamps. It takes time. However, in conventional ignition devices, if the ignition switch 2 is operated quickly, the starter motor is started before the time required for self-diagnosis has elapsed after the electrical components 8 are energized, and this causes the power supply voltage to drop and the self-diagnosis to occur. There is a problem that the diagnostic system malfunctions or the diagnosis is interrupted without being completed.

(Object and Structure of the Invention) The present invention has been made in view of the above points, and an object of the present invention is to ensure self-diagnosis of electrical components when starting an engine. After the electric components are energized at the time of starting, the energization of the starter motor is delayed by a predetermined time period necessary for self-diagnosis.

The excitation coil 10b of the relay 10 is connected between one end of the timer 11 and the ignition contact 5, and the other end of the timer 11 is grounded. The timer 11 is a timer that is turned on by being energized and turned off after a sufficient time for the electrical component 8 to perform self-diagnosis, for example, 300 m5ec, and is configured by a mono-multivibrator or a mechanical timer. .

When the engine of a vehicle is started, the ignition switch 2 is operated, the movable piece 3 rotates, and first comes into contact with the ignition contact 5. As a result, the electric component 8 is energized to start self-diagnosis, and the timer 11 is also energized to open the normally closed contact 10a of the relay 1o. Even if the movable piece 3 rotates roughly and contacts the start contact 6, the timer 1
1 is on, the contact 10a of the relay 10 is open, so the excitation coil 7b of the starter relay 7 is not energized, and the starter motor 9 does not start. After that, when a predetermined period of time has elapsed, the timer 11 is turned off, and when the contact 10a of the relay 10 is closed, the excitation coil 7b of the starter relay 7 is energized, the contact 7a of the starter relay 7 is closed, and the starter motor 9 is supplied with power, and then the engine starts running. is started. By delaying the power supply to the starter motor 9 in this manner, self-diagnosis of the electrical components can be reliably performed during that time.
