Abstract

PURPOSE: To maintain room space at suitable temperature before going on board by calling an automobile telephone from an external telephone for inputting a required signal to a controller via a connection terminal, and actuating an engine and air conditioner for starting an air conditioning process in an unmanned vehicle. CONSTITUTION: When a required signal is inputted to a controller 4 from an external telephone 21 via an automobile telephone 11, the controller 4 actuates an engine 2 after confirming that an automobile 1 does not start traveling, regardless of the actuation thereof, and a clock circuit starts counting time elapsed from an engine start. Thereafter, when the controller 4 identifies air conditioning start conditions, for example, the conditions where a speed of the engine 2 is equal to or larger than the preset number, cooling water temperature is equal to or above the preset level and the lapse of the preset time exists, an air conditioner 3 automatically operates, so that the room temperature reaches the preset level. In addition, when the preset time elapses in that state, the air conditioner 3 and the engine 2 are sequentially stopped, thereby ending an air conditioning start program on a remote operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology relating to a vehicle, and more specifically, an air conditioner (including only heating) of an unmanned vehicle is instructed via a telephone (hereinafter referred to as a car telephone) mounted on the vehicle. The present invention relates to a technique for maintaining an appropriate temperature inside a vehicle when riding.

[0002]

2. Description of the Related Art As a technique of this kind, for example, Shoukaikai 61
No. 128861, Japanese Utility Model Laid-Open No. 61-174250, JP-A-1-195974, JP-A-2-231855, JP-A-3-176226 and the like have already been proposed.

However, in Japanese Utility Model Laid-Open No. 61-128861,
Since this is a technology for simply starting the engine from the telephone outside the vehicle via the automobile telephone, in order to perform air conditioning in the vehicle interior, the air conditioning switch is turned on in advance when getting off the vehicle as described in the embodiment. However, there is a problem that if the operator forgets to turn on the air conditioning switch, the air conditioning in the vehicle compartment cannot be performed even if the engine is remotely operated from the outside of the vehicle and started.

Further, since the engine is started with the air-conditioning switch turned on, there is a problem that the engine load is large at the time of starting and idling, which accelerates deterioration of the engine, engine oil and the like.

Further, in the case of this device, the operation of the air conditioner is stopped when the interior of the vehicle is air-conditioned to a predetermined temperature, but since there is no mechanism for stopping the engine, boarding may be delayed or the engine may be stopped. If you forget to start and air-condition itself, the engine will rotate endlessly, fuel will be wasted wastefully, and the fuel tank will be emptied at extreme times.

In addition, when the passenger gets on ahead of schedule and operates by riding in a room where the inside of the vehicle is not air-conditioned within a predetermined temperature range, if the inside of the vehicle reaches a predetermined temperature during operation, the vehicle will be operated from outside the vehicle. There is also a problem that the air conditioner started by remote control stops and it is necessary to restart the air conditioner in the vehicle compartment.

[0007] In addition, Japanese Utility Model Laid-Open No. 61-174250 is a technique for inputting a required control signal one by one in an interactive manner, although it does not have many devices to be operated, and at first glance it seems that it is easy to operate. Has a problem in that it is troublesome to operate, cannot be used by a person who is unfamiliar with machine operation, and the operation time becomes long.

Further, in the case of this device, in order to remotely control the air conditioner or the like from the telephone outside the vehicle via the automobile telephone, the car switch (engine key referred to in the present invention) is " It is necessary to keep the accessory on, and there is no danger of theft when such a device is parked in a garage at home, but for example, park in a blue sky parking lot at a resort and return after sightseeing. When you try to start the air conditioner so that the temperature inside the vehicle will be comfortable when you arrive, you will be left unattended for a long time with the car switch plugged in, so there is a risk that the car may be stolen. There was a point.

Also, in the case of this device, even when the engine and the air conditioner that have been started are stopped, remote operation using a telephone is required.
It was necessary to operate the phone again to shut down the engine and air conditioner.

However, the remote control for this stop is
It is difficult to actually carry out because it has the consciousness that "I will drive immediately anyway" and that if I perform a stop operation, I need a remote operation to start it again before getting on, There was a problem that was consumed by mischief. There was also the danger of emptying the fuel tank by forgetting that the engine was started and air conditioning was being performed.

Further, in the air conditioning method disclosed in the embodiment,
When the passenger gets on ahead of schedule and operates while the passenger compartment is not air-conditioned within a predetermined temperature range, as in the case of JP-A-61-128861, the passenger compartment is When the temperature reaches a predetermined temperature, the air conditioner started by remote operation from outside the vehicle using a telephone is stopped, and there is also a problem that it is necessary to restart the air conditioner inside the vehicle.

Also, in the case of Japanese Patent Laid-Open No. 195974/1989, the air conditioner stops when the temperature inside the vehicle reaches a predetermined temperature, but since there is no engine stop mechanism, the ride may be delayed or the engine may be turned off. If you forget to start and air conditioning, the engine will rotate endlessly,
When fuel is wasted and the fuel tank is emptied when it is extremely heavy, or when the passenger gets on the train earlier than planned, and the passenger compartment is not air-conditioned within the specified temperature range When the temperature inside the vehicle reaches a predetermined temperature, the air conditioner that was remotely operated from the outside of the vehicle is stopped, and the air conditioner must be restarted in the vehicle. There was a problem similar to the issue.

Further, in the case of Japanese Patent Laid-Open No. 2-231855, it is possible to instruct start and stop of the engine and the air conditioner, but since there is no mechanism for automatically stopping, it is referred to as the above-mentioned Japanese Utility Model Laid-Open No. 61-174250. Similarly, in order to stop the engine and air conditioner that have been started, it is necessary to perform remote control by telephone.Therefore, if the boarding schedule is extended, it is necessary to operate the phone again to stop the engine and air conditioner. was there.

As described above, the remote control for stopping the vehicle has the consciousness that "you must drive immediately." Since it is necessary to operate, it is a difficult operation to actually carry out, and I have forgotten the problem that it consumes fuel mischievously and the fact that the engine is started and air-conditioning itself, the fuel tank There was a danger of emptying.

Further, in Japanese Patent Laid-Open No. 3-176226, the engine and the air conditioner that have been started can be stopped when it is judged by the fuel remaining amount detecting means that the vehicle cannot run. As for the fuel, this means that the engine will continue to rotate until there is almost no fuel left, so if you forget the fact that the boarding schedule extends earlier or you start the engine and air conditioning,
It was uneconomical to waste fuel.

Further, the operation of the engine and the air conditioner which are remotely activated from the outside of the vehicle is stopped when the information entered by a person such as a door being opened is input. Therefore, it is necessary to restart after getting on the vehicle. There was also a problem that the operation was troublesome.

The car telephone 11 is a telephone 2 outside the car.
In addition to being able to have a normal voice conversation with 1, the personal identification number transmitted by the telephone 21 is collated with the previously stored personal identification number, and if the personal identification numbers match, the control code transmitted by the telephone 21 is input. Then, a model having a conventionally known function is selected.

The function of collating the above-mentioned personal identification number is
It is also possible to configure the controller 4 so that the controller 4 mounted on the automobile 1 can perform this.

The connection terminal 5 may be a conventionally known terminal to which one end of the signal line having the other end connected to the modem 12 can be connected by inserting or screwing.

Further, the controller 4 is, for example, as shown in FIG. 2, a control processing unit (C) including a microcomputer.
PU) 40, and stores the data of each detection signal, each setting signal, etc. fetched from the input / output port 41 in a readable / erasable memory (RAM) 42, and at the same time, a clock circuit 43, for example, for a calendar. Year / month /
Data such as day / time is obtained, and required arithmetic processing is performed based on each of these data by a control processing program stored in a read-only memory (hereinafter referred to as ROM) 44. Each control signal to be output is output from the input / output port 41, and required data contents such as engine speed, vehicle speed, cooling water temperature, remaining fuel amount, and operating state are displayed on the display unit 45. There is.

The ROM 44 includes an ignition timing control device, an electronic fuel injection device, an electronically controlled automatic transmission, an ABS device, an airbag starting device, a door lock device, which are not shown.
Along with a program for controlling an electronic tuning radio and the like, when the air conditioning switches 8 are operated, the interior of the vehicle is controlled to a predetermined temperature or a predetermined temperature range. It is a conventionally known air conditioning control program and a preset predetermined control. A remote control air-conditioning start control program, which operates when a code is input from the telephone 21 via the automobile telephone 11 and the input / output port 41, is stored.

That is, when a predetermined control code is input, the controller 4 starts step S1 to start the engine 2, for example, a hand brake (not shown) is applied, and a shift lever (not shown) is in a parking position. It is confirmed by various sensors not shown that the vehicle 1 is in a state in which it does not start even if the engine 2 is started, such as in the neutral position, and the engine key 6 is inserted into the key hole 7 to drive ( When it is confirmed that the engine is not set to the ON position (no preparation for operation), the process proceeds to step S2 to start the engine 2, and further proceeds to step S3 to elapse time after the engine is started by the timing circuit 43. Start timing.

If it is determined in step S1 that the vehicle 1 may start when the engine 2 is started, it is dangerous to start the engine 2 as it is. To finish. In this case, the fact that the air conditioning is not possible can be configured to be transmitted to the person who is remotely controlling the air conditioning by voice or the like via the car telephone 11 and the telephone 21.

In step S4, the rotation of the engine 2 is started, for example, when the engine 2 starts to rotate at a speed higher than a predetermined speed, the temperature of the cooling water becomes higher than a predetermined temperature, or a predetermined time elapses. It is confirmed that it is stable by an appropriate sensor (not shown), and if this is confirmed, the process proceeds to step S5 and the air conditioner 3 is started.

On the other hand, if the determination in step S4 is NO, that is, if the air conditioning start condition is not satisfied, the process proceeds to step S9 and the first predetermined time (for example, 5 minutes) has elapsed. It is determined whether or not. If the result is NO, the process returns to step 4, and if the result is YES, the process proceeds to step S10.

That is, when the air conditioning start condition is satisfied before the first predetermined time elapses, the process proceeds to step S5 and the air conditioner 3 is activated, and the air conditioning is performed even after the first predetermined time elapses. If the conditions are not met, step S
The program shifts to 10 and the engine 2 is stopped, and this air conditioning start program by remote control is terminated.

The air conditioner 3 may be a so-called automatic air conditioner that automatically operates so that the temperature detected by a temperature sensor (not shown) for detecting the vehicle interior temperature becomes the temperature set by the air conditioning switches 8 or the air conditioner. Alternatively, the heating or heating may be designated and the cooling or heating operation may be interrupted when the temperature reaches a predetermined temperature, and the operation may be restarted when the temperature deviates from the predetermined temperature. Alternatively, the cooling or heating operation may be simply performed.

In step S6, it is determined whether or not a second predetermined time (for example, 15 minutes) has passed. If it is determined that the second predetermined time has passed, step S6.
7, it is determined whether the engine key 6 is set in the operating position of the key hole 7, and if it is confirmed that the engine key 6 is not set in the operating position, the process proceeds to step S8 and the air conditioning is performed. The device 3 and the engine 2 are sequentially stopped, and the air conditioning start program by remote control is ended.

If the result of the determination in step S7 is NO, that is, if the engine key 6 has been set to the driving position in the key hole 7, the driver has boarded and is preparing to drive. Is meant,
Without stopping the engine 2 and the air conditioner 3, the process proceeds to step S11 and the normal engine control by the engine key 6 and the normal air conditioning control by the air conditioning switches 8 are started, and the respective switches are instructed to stop. At that point, the operation of the corresponding device is stopped.

As described above, in the automobile 1 of the present invention, the controller 4 is provided from the telephone 21 outside the vehicle via the telephone 11 of the automobile.
By inputting a predetermined control signal to the engine 2, the engine 2 is started and the air conditioner 3 is started, and the passenger compartment of the unmanned automobile 1 is air-conditioned, so that comfortable driving can be performed from the time of riding.

Especially, since the engine 2 automatically stops after a predetermined time has passed, not only is the safety high,
It does not waste fuel such as gasoline.

Since the present invention is not limited to the above embodiments, various modifications can be made without departing from the spirit of the claims.

For example, it is possible to configure the controller 4 so that the engine 2 is started at a predetermined time or after a predetermined time by a signal input from the telephone 21.

Even if it is determined to be no in step S1, if the reason for determining no can be eliminated, for example, if the shift lever is in the drive position and it is determined to be no, the shift lever is parked or neutralized. It is also possible to provide a control step for changing to the position of, and then return to step S1 to determine the engine start condition again.

Further, the judgment operation of step S7 is added to an appropriate position before step S6, and at any step of a series of air conditioning start programs using this telephone, the engine key 6 is inserted into the key hole 7, It is also possible to maintain the operations of the engine 2 and the air conditioner 3 at that time, and immediately shift to the normal control of the engine 2 by the engine key 6 and the normal control of the air conditioner 3 by the air conditioning switches 8. it can.

It is also possible to configure the controller 4 so that the second predetermined time for determining the stop time of the engine 2 can be selected by the control code input from the telephone 21.

The controller 4 may be divided into a plurality of groups for each control target group.
