Description

[Detailed description of the invention] [Field of application of the invention] The invention relates to a remotely controlled diesel vehicle,
In particular, the present invention relates to a control device for a remote-controlled diesel vehicle suitable for a diesel vehicle operated by a wireless device.

[Background of the idea]

In conventional remote-controlled diesel vehicles, starting and stopping operations for the engine are performed from inside the driver's cab of the vehicle or from the outer periphery of the vehicle body.
Furthermore, since the system is operated remotely, the driver very often operates the system from a location where it is easy to perform other checking tasks, ie, from a location other than the driver's cab or the vicinity of the vehicle body. Therefore, in order to stop the engine when the vehicle is on standby, the driver must move to the cab of the vehicle or near the vehicle body, which is cumbersome. Furthermore, since leaving the engine running during standby will waste fuel, it is conceivable to start and stop the engine by remote control. However, in remote control using a wireless device, increasing the number of command signals associated with starting and stopping the engine increases the size and weight of the wireless transmitter, making the operation complicated and burdening the driver. The disadvantage is that it increases.

[Purpose of invention]

In view of the above points, the present invention aims to shorten the operating time of the engine while the vehicle is on standby as much as possible without increasing the burden on the driver.

[Summary of the idea]

This invention allows a control device installed in a vehicle to automatically stop the engine after a certain period of time has passed after the vehicle has stopped, based on control commands from a wireless device and vehicle operating information. The present invention is characterized in that the engine operating time while the vehicle is stopped is shortened as much as possible by controlling the control signal.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a block diagram showing an embodiment of a control system for a remotely controlled diesel vehicle according to the present invention. In the figure, a wireless transmitter 1 transmits signals such as driving, braking, horn, and reversing gear switching commands.
The respective signals are received by the wireless receiver 2 and outputted by the relay. Among these, the power, brake, and horn signals are input to the automatic driving device 4 via the engine operation control device 3, and output from the automatic driving device 4 to the vehicle body control circuit 5 in accordance with the input signals. The engine operation control device 3 outputs an engine stop/start command signal to the vehicle body control circuit 5 based on command information from the wireless transmitter 1 and vehicle operation information from the sensor section 6. Signals other than the engine, brake, and horn signals are directly output from the wireless receiver 2 to the automatic driving device 4, and the automatic driving device receives the engine notch signal and the brake notch signal based on the command signal and the vehicle operation information from the sensor unit 6. etc. are calculated and output.

Next, FIG. 2 is a circuit diagram showing the configuration of the engine operation control device. In the figure, the engine operation control device 3 includes a control section 31, a printer 32,
It is composed of a contact output circuit 33 and a power supply section 34. Among these, the control section 31 is the arithmetic logic section 31
a, clock generator 31b, printer drive unit 3
1c. The sensor section 6 obtains vehicle operation information and is comprised of a speed sensor 61, an engine rotation sensor 62, a clutch position sensor 63, a brake pressure sensor 64, an air pressure sensor 65, a temperature sensor 66, and the like. The signal from the sensor section 6 is input to the arithmetic logic section 31a. The arithmetic logic section 31a performs calculation, judgment, and command processing in conjunction with the signal input from the radio receiver 2 and the previously input basic data. Clock generator 31b
The arithmetic logic section 31a associates the calculation judgment with a time element, and the printer drive section 31c controls the printer 32 that prints out information for processing the judgment command in the arithmetic logic section 31a.

In such a configuration, for example, a signal other than the wireless command signal "Go" is input to the control section 31, and the sensor section 6 outputs signals such as "speed", "brake pressure", "engine rotation", "clutch position", etc. A signal is input, and the arithmetic logic unit 31a detects whether the vehicle is stopped, the brake is applied, the clutch is in neutral, or the engine is rotating;
And if the same state continues for a set time,
"Honk horn" and "engine stop" commands are output to the vehicle body control circuit 5 via the contact output circuit. In response to this input signal, the vehicle body control circuit operates the horn and engine stop operation circuit to sound the horn and stop the engine.

On the other hand, the arithmetic logic section 31a detects that the engine has stopped using the engine rotation sensor 62, and controls the printer drive section 31c and the printer 32 in order to print out the information.
The printer 32 has the date, time and time “ENGINE
Print out "STOP". When the engine stops, the power to the vehicle body control circuit 5 is turned off and the functions are stopped, so that the wireless transmitter 2 cannot perform "drive" and "brake" controls, so the vehicle will not run. Wait with the engine stopped and the brake applied.

Next, when starting the vehicle, the radio receiver 2 receives the "brake" and "honk" command signals from the radio transmitter 1 and inputs them to the arithmetic logic unit 31a.
In the arithmetic logic section 31a, the engine rotation sensor 62
It detects that the engine is stopped based on the signal from the engine, and outputs "horn", "preheat", and "engine start" commands to the vehicle body control circuit 5 via the contact output circuit. The vehicle body control circuit 5 operates a horn, preheating, and engine starting circuit to sound the horn and preheat and start the engine. In this way, the engine is started. At this time, it is possible to distinguish between starting the engine and when the starting has failed by changing the way the horn sounds, and notifying the driver. Also,
It is also possible to easily replace the horn with a voice.

As described above, when the engine starts, the printer drive unit 3 detects the rotation of the engine and prints out information at the time of starting.
1c and printer 32. The printer 32 displays the date, time, and "ENGINE START"
print out. In addition, the vehicle body control circuit 5 is powered on by the "brake" and "horn" signals.
Therefore, the vehicle can be operated normally by the command signal from the wireless transmitter 1 after the engine is started. When the engine is stopped and on standby, the sensor unit 6 detects information from each part of the vehicle and adjusts the cooling water temperature, air pressure, and brake pressure to make it easier to start the engine and operate the entire vehicle. , when the temperature falls below the specified value, the arithmetic logic section 31a determines and calculates and outputs "horn", "preheat", and "engine start" commands to start the engine. After starting, the engine will stop if the stop conditions are met.

According to such a configuration, the engine can be automatically stopped when the engine is idle, and the engine can be started according to commands from the wireless transmitter, without adding a special command signal circuit to the conventional wireless transmitter. Since the engine can be started, the idle time of the engine can be significantly reduced, which has a great effect on fuel savings. In addition, the operating hours of each device per day are reduced, and the replacement cycle of parts can be extended.
Maintenance costs can be reduced. Furthermore, since the printer 32 records the engine stop/start trends, the operating status of the vehicle can be easily managed.

[Effect of idea]

As explained above, according to the present invention, engine start/stop control can be performed without adding special functions to the remote control device, so the engine can be operated while the vehicle is on standby without increasing the burden on the driver. The operating time can be shortened.
