JPS6220674A - Automatic starter for automobile engine - Google Patents

Abstract

PURPOSE:To permit the automatic start of an engine at a desired set time by the simple and inexpensive constitution by connecting a timer with an engine starting circuit and an ignition circuit, thus avoiding the necessity of expensive radio equipment. CONSTITUTION:A timer 1 is connected to an engine starting circuit 6 and an ignition circuit 7. Further, a neutral detection circuit 2, brake detection circuit 3, and a revolution-speed detecting circuit 4 are connected to the timer 1. The operating timing of the timer 1 is arbitrarily set by the timer setting 8. Therefore, at a desired set time by the timer set 8, the timer 1 puts the starting circuit 6 and the ignition circuit 7 into electric conduction, and starts an engine. When the revolution speed of the engine becomes over the idling revolution speed, the timer 1 stops the conduction of the starting circuit 6, and the engine start is completed. Therefore, the engine can be automatically started at the desired set time by the simple and inexpensive constitution.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic starting device for an automobile engine that can automatically start an automobile engine at a desired set time (conventional technology ) Generally, an automobile engine does not warm up immediately after being started, so it is necessary to leave the engine idling for a while.

In addition, in the winter, the heater may not work immediately after starting the engine, or in the summer, the cooler may not work immediately, so the driver may have to start the engine before starting the car. must be started and the heater or cooler must be running.

Conventionally, a receiver switch circuit connected to the engine starting circuit and ignition circuit is installed in the car, and a transmitter activates the receiver switch circuit to start the engine by wireless remote control. A starting device has been developed.

(Problems to be Solved by the Invention) Although such conventional technology can meet the above-mentioned requirements, due to its configuration, the radio reception and transmission equipment is expensive and cannot be provided at a low price. In addition, it is unsafe because there is a risk of malfunction due to interference, etc. Furthermore, since it is a low-power wireless equipment, its operating range is limited to 100 meters. there were.

(Means for Solving the Problems) In order to solve these problems, according to the present invention, a timer that can be set at any time is linked to the engine starting circuit and the ignition circuit. An automatic starting device for an automobile engine is provided, which is characterized in that the engine is automatically started at a desired time.

In the above configuration, the timer can intermittently energize the engine starting circuit when the set time has come.

In this case, battery consumption can be reduced and the engine can be started easily.

Furthermore, in the above configuration, the timer can release the connection between the engine starting circuit and the ignition circuit if the engine does not exceed a predetermined rotational speed value within a predetermined time after the set time has arrived. .

In this case, when the engine does not start due to a malfunction or the like, it is possible to automatically stop the engine from starting.

Furthermore, in the above configuration, the timer can be set to an arbitrary time programmatically, such as an arbitrary time within a day, an arbitrary time within several days, or a periodic arbitrary time. .

In this case, the number of settings can be reduced, and forgetting the settings can be prevented.Furthermore, in the above configuration, even if the engine is started after the set time, the timer is set so that the key is not pressed within a predetermined time. Without operating a switch, the connection between the engine starting circuit and the ignition circuit can be released.

In this case, even if the driver forgets that the engine has started, the engine can be automatically stopped.

Also, in the above configuration, the timer can start the engine at the set time only when it confirms that the transmission is in neutral. Furthermore, in the above configuration, the timer confirms that the car's parking brake is applied. The engine can be started at the set time.

(effect) The above technical means works as follows.

At a set time, the timer turns the starter motor by energizing the engine's ignition circuit and the engine's starting circuit.

When the engine starts due to the rotation of the starter motor, the timer detects the engine speed and confirms that the engine speed is higher than the idling speed, and then stops the power supply to the engine starting circuit. Engine starting is complete.

(Embodiment) An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a system diagram, and (1) is a timer connected to an engine starting circuit (6) and an ignition circuit (7), respectively. .

(2) is a neutral detection circuit that confirms that the transmission is in neutral; (3) is a brake detection circuit that confirms that the parking brake is applied; (4)
is a rotation speed detection circuit that confirms that the engine rotation speed has reached the idling speed.

(8) is a timer setting for arbitrarily setting the operating time of the timer (fl) so that the timer (1) starts operating at a desired time.

(IA) is the operating time A that controls the operating time of the timer (11), and the operating time A (LA) is, as shown in FIG. After confirming, the ignition circuit (7
) enters at point a, and the engine starts normally by turning on the starting circuit (6) from C to d, and the rotation speed detection circuit (4) operates at point e, starting the starting circuit (6).
When the energization to is stopped and the key switch (9) is not operated because the driver does not come after a predetermined time elapses, when the predetermined time g comes, the ignition circuit (7) switches to The rotation speed detection circuit (4) stops at f and controls the operating time of the timer (1).

(IB) is the operating time B that controls the operating time of the timer (1), and the operating time B (IB) is the third
As shown in the figure, the timer (1) operates at the set time,
The ignition circuit (7) enters at a, the starting circuit (6) enters at C
If the engine does not start and the rotation speed detection circuit (4) does not operate even if the power is intermittently supplied from to d, and when the predetermined operating time elapses from h, it is assumed that the engine is abnormal and the subsequent timer ( This is to stop the operation of step 1) and control the operation time.

(Effects of the Invention) As explained above, the present invention is capable of automatically starting an engine at a desired set time without using any expensive wireless equipment, and can be provided at a low cost. At the same time, there is no risk of malfunction due to interference, etc., and there is no possibility that the operating range will be limited.
This has the effect of making it possible to start the engine reliably.
