  When the refrigeration / refrigerating vehicle 1 is driven and the refrigeration apparatus 4 is driven while the refrigeration / refrigeration vehicle 1 is stopped (or parked) by reading out the storage room temperature control mode program of the refrigerator / refrigeration vehicle 1, The gear 18 of the refrigerator car 1 is put into neutral (or it is confirmed that the gear 18 is neutral). Further, the driver or the like pulls the hand brake 26 (or confirms that the hand brake 26 is pulled). Further, the driver or the like confirms that the frozen / refrigerated vehicle 1 is stopped (or stopped) by perception or by the speedometer 31 or the like.

  Next, in step S1, a driver or the like inserts a key (not shown) into the ignition switch 8 and turns on the power switch 8a (or already has a key (not shown) in the ignition switch 8). If it is inserted, the power switch 8a is turned on by operating a key (not shown).)

  In the refrigerator / refrigerator vehicle 1, in step S1, the driver or the like turns on the travel mode luggage compartment temperature control means on / off switch means SW1 and turns on the stop mode luggage compartment temperature control means on / off switch means SW3. . At this time, the idle stop device on / off switch means SW2 is turned off.

  In step S1, the power switch 8a is turned on, the travel mode luggage compartment temperature control means on / off switch means SW1 is turned on, the stop mode luggage compartment temperature control means on / off switch means SW3 is turned on, and the idle stop device is turned on / off. When the switch means SW2 is turned off, the luggage compartment temperature control means (CPU) 15 determines whether or not the handbrake 26 is pulled in step S2 and whether or not the gear 18 is neutral. The vehicle speed is diagnosed as to whether it is 0 km / h.

  In the refrigerator / refrigerator 1, when the hand brake 26 is pulled, the switch means 28 is turned on, and the luggage compartment temperature control means (CPU) 15 is connected to the luggage compartment temperature control means (CPU) 15 via the signal line L 13. Since a predetermined voltage signal (or a predetermined current signal) is sent, a predetermined voltage signal (or a predetermined current signal) is sent to the luggage compartment temperature control means (CPU) 15 via the signal line L13. When it is sent, it is determined that the handbrake 26 is pulled, and a predetermined voltage signal (or a predetermined voltage) is sent to the luggage compartment temperature control means (CPU) 15 via the signal line L13. If the current signal is not sent, it is determined that the hand brake 26 is not pulled.

  Further, in this refrigeration / refrigeration vehicle 1, whether or not the gear 18 is neutral is determined based on the gear position information detected by the gear position detection sensor 19 using a signal line L6, an engine control unit (ECU (electronic control unit)). 16 and the signal line L11 are transmitted to the luggage compartment temperature control means (CPU) 15, so the luggage compartment temperature control means (CPU) 15 indicates that the gear position information detected by the gear position detection sensor 19 is neutral. When the gear 18 is determined to be neutral, the gear position information detected by the gear position detection sensor 19 is a signal other than the neutral signal. I try to judge that it is not neutral.

  Further, in the refrigerated / refrigerated vehicle 1, whether the vehicle speed of the refrigerated / refrigerated vehicle 1 is 0 km / h is determined based on the vehicle speed signal detected by the vehicle speed sensor 30.

  In other words, in the refrigerated / refrigerated vehicle 1, the vehicle speed signal detected by the vehicle speed sensor 30 is transmitted to the engine control unit (ECU) 16 via the signal line L8, and then the engine control unit. (ECU (Electronic Control Unit)) 16 is changed to a speed signal via signal line L9 and data converter 32, and then displayed on speedometer 31. In the refrigerator / refrigerator 1, the vehicle speed (km / h) displayed on the speedometer 31 is transmitted to the luggage compartment temperature control means (CPU) 15 via the signal line L 17. When the vehicle speed Sp (km / h) displayed on the speedometer 31 is 0 km / h (Sp = 0 km / h), the indoor temperature control means (CPU) 15 stops the refrigeration / refrigeration vehicle 1. If the vehicle speed Sp (km / h) is greater than 0 km / h (Sp> 0 km / h), the refrigeration / refrigeration vehicle 1 is moving. I am trying to judge.

  In the refrigerator / refrigerator 1, the luggage compartment temperature control means (CPU) 15 determines that the hand brake 26 is pulled in step S 2, and determines that the gear 18 is neutral. When the vehicle speed of the refrigerated / refrigerated vehicle 1 is determined to be 0 km / h, the stop mode luggage room temperature stored in the storage means (not shown) of the luggage compartment temperature control means (CPU) 15. The control mode program is read so that the temperature in the luggage compartment 3 can be controlled when the refrigerator / refrigerator vehicle 1 is stopped (or parked).

  In the refrigerator / refrigerator vehicle 1, when the travel mode luggage compartment temperature control means on / off switch means SW1 is turned on in step S3, the display means (for example, the operation panel portion 15A of the luggage compartment temperature control means (CPU) 15) (for example, If the set temperature Tth in the luggage compartment 3 is the default value, the driver or the like in step S4 causes the driver or the like to display the display unit (for example, the liquid crystal display unit) 15e. While referring to the displayed set temperature Tth, the temperature setting operation sections 15a1 and 15a2 of the temperature setting means 15 are appropriately operated to set the set temperature Tth in the luggage compartment 3 (in FIG. 3, as an example of the set temperature Tth). The case where the set temperature Tth is set to −5.0 ° C. is illustrated, but this is merely an example.) The set temperature Tth of the luggage compartment 3 input by appropriately operating the temperature setting operation sections 15a1 and 15a2 of the temperature setting means 15a by pressing the temperature determination switch 15d is the temperature of the luggage compartment temperature control means (CPU) 15. It is stored in a storage means (not shown).

  The luggage compartment temperature control means (CPU) 15 has two threshold values (based on the set temperature Tth of the luggage compartment 3 stored in the storage means (not shown) of the luggage compartment temperature control means (CPU) 15). An upper threshold temperature (Tth + β) and a lower threshold temperature (Tth−α) in the luggage compartment 3 are set.

  The upper threshold temperature (Tth + β) is not particularly limited to the following case, but is set to Tth + 1 (° C.), for example.

  Further, the lower threshold temperature (Tth-α) is not particularly limited to the following case, but is set to, for example, Tth-1 (° C.).

  On the other hand, in the refrigerator / refrigerator 1, the set temperature Tth in the luggage compartment 3 is already set and stored in storage means (not shown) of the luggage compartment temperature control means (CPU) 15. In the case where the temperature setting operation sections 15a1 and 15a2 of the temperature setting means 15 are not appropriately operated, the storage means (not shown) of the luggage compartment temperature control means (CPU) 15 is already provided in step S3. ) To control the temperature in the luggage compartment 3 based on the set temperature Tth stored in (), while the preset temperature Tth in the luggage compartment 3 has already been set, It is a case where it is stored in the storage means (not shown) of the control means (CPU) 15, and in step S4, the temperature setting operation sections 15a1 and 15a2 of the temperature setting means 15 are appropriately operated, and then If pressed a constant temperature determination switch 15d, based on the set temperature Tth newly set (n), it is adapted to the temperature control of the loading space 3.

  In this refrigerator / refrigerator 1, in step S 5, the set temperature Tth set by the temperature setting means 15 of the luggage compartment temperature control means (CPU) 15 and the temperature in the luggage compartment 3 measured by the temperature sensor St Is compared with the set temperature Tth set by the temperature setting means 15 and the temperature T in the luggage compartment 3 measured by the temperature sensor St.

  In this refrigeration / refrigeration vehicle 1, the luggage compartment temperature control means (CPU) based on the set temperature Tth set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15. ) The lower threshold temperature (Tth−α) set by 15 is compared with the temperature T in the luggage compartment 3 measured by the temperature sensor St (Steps S6 and S7 are compared). reference.).

  Further, in the refrigerator / refrigerator vehicle 1, the luggage compartment temperature control means based on the set temperature Tth set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15. The upper limit threshold temperature (Tth + β) set by the (CPU) 15 and the temperature T in the luggage compartment 3 measured by the temperature sensor St are compared (Steps S7 and S8 are compared). reference.).

  In the refrigerator / refrigerator 1, the temperature is set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15, and is set to the set temperature Tth set by the temperature setting means 15. Based on the result, the lower limit threshold temperature (Tth−α) set by the luggage compartment temperature control means (CPU) 15 is compared with the temperature T in the luggage compartment 3 measured by the temperature sensor St. When the temperature T in the luggage compartment 3 measured by the sensor St is lower than the lower threshold temperature (Tth−α) (T <Tth−α) (see step S6), the luggage is loaded in step S9. A signal for turning on (opening) the electromagnetic valve v1 is sent from the room temperature control means (CPU) 15 via the signal line L3, the electromagnetic valve v1 is turned on (opened), and the luggage room temperature control means (CPU) 1) From the signal line L4, a signal for turning off (closing) the electromagnetic valve v2 is sent, the electromagnetic valve v2 is turned off (closed), and the signal temperature L1 from the luggage compartment temperature control means (CPU) 15 is changed. Then, a signal for turning on the starting motor drive switch 8b is sent for a predetermined time, and a fuel pump (not shown) is driven from the luggage compartment temperature control means (CPU) 15 via the signal line L10. A signal for turning on (opening) the fuel supply stop valve (solenoid valve) and a signal for turning on the electromagnetic switch means 14 from the luggage compartment temperature control means (CPU) 15 via the signal line L5. Is sent out.

  In the refrigeration / refrigeration vehicle 1, the traveling engine 5 is driven by the operation shown in step S9 (see step S10), the electromagnetic clutch means 10 is in the connected state, and the belt means B and the electromagnetic clutch means 10 are connected. Thus, the power of the traveling engine 5 is transmitted to the compressor 9, the compressor 9 is driven (see step S11), and the defroster 13 is driven (see step S12), so that the temperature in the luggage compartment 3 is increased. Is controlled to a temperature (T ≧ Tth−α) that is equal to or higher than the lower threshold temperature (Tth−α).

  Further, in the refrigerator / refrigerator vehicle 1, the temperature is set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15, and is set to the set temperature Tth set by the temperature setting means 15. Based on the result, the lower limit threshold temperature (Tth−α) set by the luggage compartment temperature control means (CPU) 15 is compared with the temperature T in the luggage compartment 3 measured by the temperature sensor St. The upper limit threshold temperature (Tth + β) set by the luggage compartment temperature control means (CPU) 15 based on the set temperature Tth set by the setting means 15 and set by the temperature setting means 15 and the temperature sensor St As a result of comparing the measured temperature T in the luggage compartment 3, the temperature T in the luggage compartment 3 measured by the temperature sensor St is equal to or higher than the lower threshold temperature (Tth−α) (T ≧ Tth− ) And when the temperature T in the luggage compartment 3 is in the range equal to or lower than the upper threshold temperature (Tth + β) (Tth−α ≦ T ≦ Tth + β), the luggage compartment temperature control means (CPU) 15 A signal for turning on the motor drive switch 8b to the starter motor drive switch 8b, a signal for turning on or off the electromagnetic valve v1, a signal for turning on or off the electromagnetic valve v2, a fuel pump ( (Not shown) is driven, and a signal for turning on (opening) the fuel supply stop valve (solenoid valve) and a signal for turning on the electromagnetic switch means 14 are not sent.

As a result, in this refrigeration / refrigeration vehicle 1, the set temperature Tth set by the temperature setting means 15 and set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15. As a result of comparing the lower limit threshold temperature (Tth−α) set by the luggage compartment temperature control means (CPU) 15 with the temperature T in the luggage compartment 3 measured by the temperature sensor St, The upper limit threshold temperature (Tth + β) set by the luggage compartment temperature control means (CPU) 15 based on the set temperature Tth set by the temperature setting means 15 and the temperature sensor St. The temperature T in the luggage compartment 3 measured by the temperature sensor St is equal to or higher than the lower threshold temperature (Tth−α) (T ≧ Tt). −α) and the temperature T in the luggage compartment 3 is in the range equal to or lower than the upper threshold temperature (Tth + β) (Tth−α ≦ T ≦ Tth + β), the traveling engine 6 is stopped. In this case, the traveling engine 6 continues to be stopped, and when the traveling engine 6 is driven, the traveling engine 6 is stopped (in this case, a fuel pump (not shown)). Is driven and the fuel supply stop valve (solenoid valve) is turned on (open), the fuel pump (not shown) is stopped and the fuel supply stop valve (solenoid valve) is turned off (closed). As a result, the cooling device 4 is also stopped.

  Further, in the refrigerator / refrigerator vehicle 1, the temperature is set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15, and is set to the set temperature Tth set by the temperature setting means 15. Based on the result, the upper limit threshold temperature (Tth + β) set by the luggage compartment temperature control means (CPU) 15 is compared with the temperature T in the luggage compartment 3 measured by the temperature sensor St. As a result, the temperature sensor St When the temperature T in the luggage compartment 3 measured by exceeds the upper threshold temperature (Tth + β) (T> Tth + β) (see step S8), in step 14, the luggage compartment temperature control means ( CPU) 15 sends a signal to turn off (close) the electromagnetic valve v1 via the signal line L3, the electromagnetic valve v1 is turned off (closed), and the luggage compartment temperature control means (CPU) 1 From the signal line L4, a signal for turning on (opening) the electromagnetic valve v2 is sent, the electromagnetic valve v2 is turned on (opening), and the signal line L1 is connected from the luggage compartment temperature control means (CPU) 15 to the signal line L1.

Thus, the power of the traveling engine 5 is transmitted to the compressor 9, the compressor 9 is driven (see step S16), and the evaporator 12 is driven (see step S17), so that the temperature in the luggage compartment 3 is increased. Is controlled to a temperature (T ≦ Tth + β) that is equal to or lower than the upper threshold temperature (Tth + β).

  In the frozen / refrigerated vehicle 1, even when the vehicle is stopped or parked, when the driver or the like selects the stop mode luggage compartment temperature control mode, the driver or the like operates as described above. As long as it is not turned off, the temperature T in the luggage compartment 3 is set to the lower threshold temperature (Tth−α) or more (T ≧ Tth−α) and the temperature T in the luggage compartment 3 is When the temperature is within the upper threshold temperature (Tth + β) or lower (Tth−α ≦ T ≦ Tth + β), the control can be performed.

  In this freezing / refrigerated vehicle 1, even if the driver or the like selects the stop mode luggage compartment temperature control mode while the frozen / refrigerated vehicle 1 is stopped or parked, the stop mode luggage compartment temperature control program During operation, when the luggage compartment temperature control means (CPU) 15 determines that the handbrake 28 is not pulled, the luggage compartment temperature control means (CPU) 15 determines that the gear 18 is not neutral. In this case, or when the luggage compartment temperature control means (CPU) 15 determines that the vehicle speed is not 0 km / h, the luggage compartment temperature control means (CPU) 15 immediately sends power to the power switch 8a. Then, a signal to turn off the power switch 8a is sent to stop the stop mode luggage compartment temperature control program (see step S2 and step S18). .).

  Further, in this refrigerated / refrigerated vehicle 1, when the refrigerated / refrigerated vehicle 1 is stopped / parked, a driver or the like selects the stop mode luggage compartment temperature control mode and drives the stop mode luggage compartment temperature control program. If the driver or the like turns off the power switch 8a with a key (not shown), the stop mode luggage compartment temperature control program is stopped (see step S18).

  Further, in this refrigerated / refrigerated vehicle 1, when the refrigerated / refrigerated vehicle 1 is stopped / parked, a driver or the like selects the stop mode luggage compartment temperature control mode and drives the stop mode luggage compartment temperature control program. When the luggage compartment temperature control means (CPU) 15 determines that the hand brake 28 is not pulled, the luggage compartment temperature control means (CPU) 15 determines that the gear 18 is not neutral. Alternatively, when the luggage compartment temperature control means (CPU) 15 determines that the vehicle speed is not 0 km / h, the luggage compartment temperature control means (CPU) 15 immediately supplies power to the power switch 8a. When a signal for turning off the switch 8a is sent and the stop mode luggage room temperature control program is stopped, or a driver or the like is turned on by a key (not shown).

  As described above in detail, the refrigeration / refrigeration vehicle 1 is stopped and parked although the refrigeration / refrigeration vehicle 1 is a refrigeration / refrigeration vehicle that drives the refrigeration apparatus 4 by the traveling engine 6. Even when the travel engine 6 is stopped, the stop mode luggage compartment temperature control means on / off switch means SW2 is turned on and the luggage compartment temperature control means (CPU) 15 is driven. On the other hand, when the temperature (T) in the luggage compartment is outside the predetermined temperature range set by the temperature setting means of the luggage compartment temperature control means, the traveling engine 6 is driven and the traveling engine 6 uses the refrigeration apparatus. 4 so that the temperature in the luggage compartment 3 can be set within a predetermined temperature range set by the temperature setting means 15A of the luggage compartment temperature control means (CPU) 15. This frozen / cold Even if a commercial power source is not installed at a place where the car 1 is parked or parked (such as a parking lot), the temperature in the luggage compartment 3 can be maintained within a predetermined temperature range. .

  As a result, when this refrigeration / refrigeration vehicle 1 is used, when the refrigeration / refrigeration vehicle 1 is stopped and parked in a place where a commercial power source is not installed (such as a parking lot), the traveling engine 6 is stopped. Even if the product is loaded), the temperature in the luggage compartment 3 can be controlled within a predetermined temperature range, so that the goods loaded in the luggage compartment 3 are not damaged.

  In the refrigerator / refrigerator 1, if the temperature in the luggage compartment 3 is outside the predetermined temperature range set by the temperature setting means 15 a of the luggage compartment temperature control means (CPU) 15, the refrigerator / refrigerator truck 1. Even when the vehicle 1 is parked and parked (when the traveling engine 6 is stopped), the interior of the luggage compartment 3 can be moved by driving the cooling device 4 by driving the traveling engine 6. Since it can be maintained at a predetermined temperature, it is not necessary to use a sub-cell, and the so-called battery of the sub-cell as seen in a refrigerator / refrigerator vehicle that drives the sub-cell and drives the cooling device There is no problem like going up.

  Further, in the refrigerator / refrigerator vehicle 1, when the refrigerator / refrigerator vehicle 1 is stopped or parked (when the traveling engine 6 is stopped), the power switch 8a of the ignition switch 8 is turned on. When the vehicle interior temperature control means (CPU) 15 is turned on and the on-off switch means SW3 is turned on and the gear 18 of the vehicle is set to neutral, the driving engine 6 is driven. Thus, even when the traveling engine 6 is driven, the vehicle does not move.

Further, in this refrigeration / refrigeration vehicle 1, when the refrigeration / refrigeration vehicle 1 is stopped and parked (when the traveling engine 6 is stopped), the power switch 8a of the ignition switch 8 is turned on. Only when the vehicle interior temperature control means (CPU) 15 is in the stop mode, the luggage compartment temperature control means on / off switch means SW3 is turned on, the vehicle gear 18 is neutral, and the hand brake 26 is pulled. Since the traveling engine 6 is driven, the vehicle does not move even when the traveling engine 6 is driven.

  As a result, in this refrigeration / refrigeration vehicle 1, since the electromagnetic clutch means 10 is off (disconnected state) even when the traveling engine 6 is driven, the power of the traveling engine 6 is supplied to the compressor 9 Therefore, the compressor 9 is in a stopped state.

  In the refrigerator / refrigerator 1, the temperature is set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15, and based on the set temperature Tth set by the temperature setting means 15. As a result of comparing the lower threshold temperature (Tth−α) set by the luggage compartment temperature control means (CPU) 15 and the temperature T in the luggage compartment 3 measured by the temperature sensor St, the temperature setting means 15 and the upper limit threshold temperature (Tth + β) set by the luggage compartment temperature control means (CPU) 15 based on the set temperature Tth set by the temperature setting means 15 and the temperature sensor St measured. As a result of comparison with the temperature T in the luggage compartment 3, the temperature T in the luggage compartment 3 measured by the temperature sensor St is equal to or higher than the lower threshold temperature (Tth−α) (T ≧ Tth−α). On the other hand, when the temperature T in the luggage compartment 3 is in the range equal to or lower than the upper threshold temperature (Tth + β) (Tth−α ≦ T ≦ Tth + β), the traveling engine 6 is driven. As a result, the cooling device 4 is also stopped (see step S33).

  Further, in the refrigerator / refrigerator vehicle 1, the temperature is set by the temperature setting means 15 by the comparison means (not shown) of the luggage compartment temperature control means (CPU) 15, and is set to the set temperature Tth set by the temperature setting means 15. Based on the result, the upper limit threshold temperature (Tth + β) set by the luggage compartment temperature control means (CPU) 15 is compared with the temperature T in the luggage compartment 3 measured by the temperature sensor St. As a result, the temperature sensor St When the temperature T in the luggage compartment 3 measured by exceeds the upper threshold temperature (Tth + β) (T> Tth + β) (see step S8), in step S34, the luggage compartment temperature control means ( CPU) 15 sends a signal for turning off (closed) electromagnetic valve v1 via signal line L3, and electromagnetic valve v1 is turned off (closed), thereby controlling the temperature inside the luggage compartment (CPU). 5, a signal for turning on (opening) the electromagnetic valve v2 is sent via the signal line L4, the electromagnetic valve v2 is turned on (opening), and a signal from the luggage compartment temperature control means (CPU) 15 A signal for turning on the electromagnetic switch means 14 is sent via the line L5.

The temperature is controlled to be T ≦ Tth + β.

  In the refrigerator / refrigerator 1, when a driver or the like turns on the idle stop device on / off switch means SW2 and turns on the starter motor drive switch 8b by operating a key (not shown), the engine control unit (ECU (Electronic control unit)) Idle stop control stored in the storage means (not shown) of the idle stop device (CPU) 17 in preference to the operation program stored in the storage means (not shown) of 16 The program has been made to work.

  That is, in the refrigerator / refrigerator vehicle 1, when a driver or the like turns on the idle stop device on / off switch means SW2 and turns on the starter motor drive switch 8b by operating a key (not shown), the engine control unit (ECU (Electronic control unit)) From 16 through the signal line L10, a signal for driving a fuel pump (not shown) and a signal for opening the fuel supply stop valve 33 are dominant, and an idle stop device (CPU) 17, a signal for driving a fuel pump (not shown) and a signal for opening the fuel supply stop valve 33 are sent via a signal line L10 (steps S37, S38 and step S37). (See S39).

  In the refrigeration / refrigeration vehicle 1, when the vehicle speed (Spkm / h) exceeds the threshold speed (Spthkm / h) during running, idle-up control is performed (see step S40). ).

  The threshold speed (Spthkm / h) is not limited to the following case, but is set to 20 km / h (Spthkm / h = 20 km / h), for example.

  In this freezing / refrigerated vehicle 1, the fact that the vehicle speed (Spkm / h) exceeded the threshold speed (Spthkm / h) during traveling indicates that the vehicle speed (Spkm / h) of the speedometer 31 is a signal. It is sent to an idle stop device (CPU) 17 via a line L17.

  In this refrigerated / refrigerated vehicle 1, during driving, after the vehicle speed (Spkm / h) exceeds the threshold speed (Spthkm / h), the driver or the like turns on (depresses) the brake 22 to switch means 24.

A signal with 36 turned on is transmitted (see step S51).

  When the idle stop device (CPU) 17 receives a signal indicating that the switch means (clutch sensor) 36 is turned on, the idle stop device (CPU) 17 transmits a signal for turning on the starting motor drive switch 8b via the signal line L19 and the signal line L1. . Further, when the idle stop device (CPU) 17 receives a signal that the switch means (clutch sensor) 36 is turned on, the fuel pump (not shown) and the fuel supply are supplied via the signal line L16 and the signal line L10. A signal for driving a fuel pump (not shown) and a signal for opening the fuel supply stop valve 33 are transmitted to each of the stop valves 33.

  In this freezing / refrigerated vehicle 1, after the traveling engine 6 is stopped (after idling stop) by the above operation, when the driver puts his or her foot on the clutch pedal 25, the switch means (clutch sensor) 36 is turned on. Then, the traveling engine 6 is again driven (see Step S51 and Step S37).
