Abstract

PURPOSE:To perform a comfortable warming-up operation and an air conditioning operation before getting on a vehicle by a method wherein a state of transmission device and a state of an auxiliary braking mechanism are detected, an electrical supplying for an ignition device is turned on or off in response to an output of this detection and at the same time an engine is automatically started when a timer shows an engine starting time. CONSTITUTION:As an operator turns on an engine starter 1 of a vehicle, an electrical current is flowed in an ignition device 2 and an engine 3 is started to operate. In turn, as the engine starter 1 is turned off, no electrical current is flowed in the ignition device 2 and then the engine 3 is stopped. In the aforesaid device, states of transmission device and auxiliary braking mechanism can be detected by a sensing device 7. A power supply switch 4 for turning on or off the electrical supplying for the ignitor device is controlled by a control device 6 in response to an output of the sensing device 7. Setting of a starting time of the engine 3 and sensing of the energization time are carried out by a timer 5. Then, when the timer 5 shows an engine starting time, the engine 3 is automatically started with a switch 8 for timer energization or deenergization.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an automatic engine start/stop device for an automobile, and more particularly to a device capable of automatically starting/stopping an automobile engine using a timer.

[Prior Art] FIG. 4 is a block diagram, not showing a conventional engine starting/stopping device for an automobile. In FIG. 4, (1) is an engine starter, (2) is an ignition device connected to the engine starter (1), and (3) is an engine connected to the ignition device (2).

Next, the operation will be explained. When the driver turns on the car's engine starter (1), the ignition system (2) is turned on.
), and the engine (3) starts.

Then, when the driver turns off the engine starter (1), electricity no longer flows to the ignition device (2) and the engine (3) stops.

[Problems to be Solved by the Invention] In the conventional engine starting/stopping device for an automobile, the driver always turns on/off the engine starter to start/stop the engine, as described below. Then, it is necessary to warm up the engine until it warms up. Also, during winter and summer, the interior of a car may be cold or hot, and it takes time to use the air conditioner to bring the interior to a comfortable temperature. Therefore, the conventional engine start/stop device has a problem in that it takes time for the driver to start the vehicle after turning on the engine starter.

This invention was made to solve the above-mentioned problems, and allows the driver to start the engine without going to the car, and also allows the driver to start the engine without going to the car. To provide an automatic engine start/stop device for an automobile that allows a driver to start the vehicle as soon as he gets in the vehicle, and allows the driver to ride in a room at a comfortable temperature by setting an air conditioner.

[Means for Solving the Problems] The automatic engine start/stop device for a vehicle according to the present invention has the following features:
A detection device that detects the state of the transmission/auxiliary brake; a control device that controls a power switch that turns on and off the supply of electricity to the ignition device according to the output of this detection device; A timer 3=- is provided for setting a starting time and detecting the starting time, and when the timer reaches the engine starting time,
It is designed to automatically start the engine.

[Operation] In this invention, the engine start time is set in a timer, and when the set time comes, the engine is automatically started.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, (1) to (3) are exactly the same as the conventional device described above. (4) is a power switch that flows current to the ignition device (2), (5) is a timer that sets and detects the startup time of the engine (3), and (6) is a power switch that turns on and off the power switch (4). Control device, (7> is transmission,
a detection device for detecting the state of an auxiliary brake (not shown);
8) is a timer start enable/disable switch for setting whether or not to start the engine using the timer (5).

Next, the operation of the embodiment will be explained with reference to FIG. First, in step (2^), the engine start time is set in the timer (5). Then, in step (2B), it is determined whether or not the timer activation switch (8) is on, and if it is off, the process returns to step (2B), and if it is on, in step (2C), the timer (5) is activated. It is determined whether the time is the set time or not, and if it is not the set time, the process returns to step (2B), and if it is the set time, the process proceeds to step (2D). Next, in step (2D), it is determined whether the transmission is in neutral or not, and if it is not in neutral, the process returns to step (2B), and if it is in neutral, it is determined in step (2D).
Proceed to 2E). Next, in step (2E), it is determined whether or not the auxiliary brake is working, and if it is not working, the process returns to step (2B), and if it is working, it is determined whether the auxiliary brake is working or not.
), the engine stop timer (5) is activated.

Then, in step (2G), it is determined whether or not it is engine stop time.

Next, in step (2G), the engine stop time is determined,
When it is not the stop time, the control device (6) outputs a large signal for the power switch (4) in step (2■), the power switch (4) is turned on in step (2■), and the power switch (4) is turned on in step (2, 1). ), current flows to the ignition device (2), and the engine operates in step (2K).Then, in step (21), the driver turns on the engine by putting the key in the engine starter (]). If it is off, go back to step (2G), and if it is on, go to step (2M) and start the timer (5).
The engine <3) operates until the engine start (1) is turned off, and the - series of operations is completed.

On the other hand, when it is the stop time in Stellaf 2G), in step (2N), the control device (6) outputs a cut-off signal for the power switch (4), and in step (20), the power switch (4) is turned off. However, in step (2P), current no longer flows to the ignition device (2), and step (2P)
At 0), the engine (3) stops and the series of operations ends.

In the above embodiment, the engine is started and stopped using a timer, but the engine may be started and stopped using a remote control instead of the timer. For example, FIG. 3 shows an operation flow using remote control. In step (3^), a receiving device (not shown) of the remote control receives a signal, and in step (3^), the remote control receiving device (not shown) receives a signal.
In B), it is determined whether the received signal is activated or not. If the received signal is activated, proceed to step (2D) in FIG. 2A, and if the received signal is stopped, proceed to step (2D) in FIG. 2A. (2N
).

Furthermore, a timer and a remote control may be used together to start and stop the engine.

[Effects of the Invention] As described above, according to the present invention, there is provided a detection device that detects the state of the transmission/auxiliary brake, and a power source that turns on and off the supply of electricity to the ignition device according to the output of the detection device. The engine is equipped with a control device for controlling the switch, and a timer connected to the control device for setting and detecting the engine start time, and automatically starts the engine when the timer indicates the engine start time. Therefore, the engine can be started automatically without the driver having to go to the car, and since the engine has been warmed up, the car can be started immediately, and the air conditioner can be set. This has the effect of allowing passengers to ride in a room with a comfortable temperature.
