[0009] A control system according to an embodiment of the present invention will be described in detail below with reference to the drawings. Note that the present invention is not limited to this embodiment. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to Fig. 1 to Fig. 5. The embodiment relates to a control system. Fig. 1 is a diagram showing the control system of the embodiment, Fig. 2 is a block diagram of the control system of the embodiment, Fig. 3 is a diagram explaining radio wave intensity, and Fig. 4 and Fig. 5 are diagrams explaining changes in radio wave intensity.

[0011] As shown in FIGS. 1 and 2, the control system 1 of this embodiment has a vehicle-side device 3 and a control unit 4. The control unit 4 of this embodiment has a terminal-side control unit 21 and a vehicle-side control unit 31. The control unit 4 changes the operation mode of at least one of the mobile terminal 2 and the vehicle-side device 3 depending on the radio wave intensity of the wireless communication between the mobile terminal 2 and the vehicle-side device 3. The mobile terminal 2 is, for example, a portable computer such as a smartphone or a tablet. The vehicle-side device 3 is a device mounted on the vehicle 100, for example, an on-board device that controls devices mounted on the vehicle 100.

[0012] 2, the mobile terminal 2 has a terminal-side control unit 21 and a communication unit 22. The communication unit 22 has a communication circuit for performing wireless communication. The communication unit 22 has a function for performing short-range wireless communication such as Bluetooth (registered trademark) or WiFi. The communication unit 22 further has a function for performing mobile communication such as 4G (4th Generation) / LTE (Long Term Evolution) or 5G (5th Generation).

[0013] The terminal-side control unit 21 changes the operation mode of the mobile terminal 2 in accordance with the radio wave intensity of the wireless communication. The terminal-side control unit 21 may be, for example, an independent application program executed on the mobile terminal 2, or may be part of an application program. The terminal-side control unit 21 may be a control program that cooperates with another application program to control the other application program.

[0014] The vehicle-side device 3 includes a vehicle-side control unit 31 and a communication unit 32. The vehicle-side control unit 31 controls the device 110 mounted on the vehicle 100. The device 110 may include, for example, any one of the vehicle 100's lamps, mirrors, displays, audio equipment, key locks, door locks, seat heaters, air conditioning equipment, window opening / closing equipment, etc., or may include other devices. The vehicle-side control unit 31 may communicate with an ECU that controls the vehicle 100. In this case, the vehicle-side control unit 31 can acquire the status of the device 110 via the ECU. The vehicle-side control unit 31 can also output a command to the ECU to change the status of the device 110. The vehicle-side control unit 31 may communicate with the device 110 via CAN communication.

[0015] The communication unit 32 has a communication circuit for performing wireless communication. The communication unit 32 has a function for performing short-range wireless communication such as Bluetooth (registered trademark) or WiFi, and performs wireless communication with the communication unit 22 of the mobile terminal 2. The communication unit 32 may also have a function for performing mobile communication such as 4G (4th Generation) / LTE (Long Term Evolution) or 5G (5th Generation).

[0016] The vehicle-side device 3 and the mobile terminal 2 work in cooperation while exchanging information via wireless communication. For example, the vehicle-side device 3 transmits information about the vehicle 100 to the mobile terminal 2. For example, the mobile terminal 2 operates the vehicle 100 via the vehicle-side device 3. The vehicle-side device 3 and the mobile terminal 2 can work in cooperation if they are capable of wireless communication with each other. For example, the vehicle-side device 3 and the mobile terminal 2 can work in cooperation regardless of whether the mobile terminal 2 is inside the vehicle 100 or not.

[0017] The vehicle-side device 3 of this embodiment has a driving mode and a non-driving mode as operation modes. The driving mode is an operation mode when the vehicle 100 is driving. In other words, the driving mode is an operation mode when the vehicle 100 is driven by the driver.

[0018] The non-driving mode is an operation mode when the vehicle 100 is not driving, for example, an operation mode when the vehicle 100 is stopped or parked. That is, the non-driving mode in this embodiment is an operation mode when the driver temporarily leaves the vehicle 100. The vehicle-side control unit 31 changes the operation mode of the vehicle-side device 3 depending on the radio wave intensity of the short-range wireless communication received by the communication unit 32. The radio wave intensity is, for example, a received signal strength RSSI (Received Signal Strength Indicator) of the communication unit 32.

[0019] 3, the radio wave strength varies depending on the distance L1 between the vehicle-side device 3 and the mobile terminal 2. When the distance L1 is short, the radio wave strength received by the vehicle-side control unit 31 is strong, and when the distance L1 is long, the radio wave strength received by the vehicle-side control unit 31 is weak. The vehicle-side control unit 31 has a threshold value for the radio wave strength and determines the degree of the radio wave strength based on the threshold value.

[0020] When the radio wave strength is stronger than the threshold, the vehicle-side control unit 31 sets the operation mode of the vehicle-side device 3 to the driving mode. On the other hand, when the radio wave strength is equal to or less than the threshold, the vehicle-side control unit 31 sets the operation mode of the vehicle-side device 3 to the non-driving mode. The threshold is, for example, a value for determining whether the mobile terminal 2 is outside the vehicle 100. The threshold may have hysteresis. That is, a first threshold for determining whether the radio wave strength has switched from strong to weak, and a second threshold for determining whether the radio wave strength has switched from weak to strong may be used. The second threshold may be a value indicating that the radio wave strength is stronger than the first threshold.

[0021] In the non-driving mode, the vehicle-side control unit 31 controls the devices 110 of the vehicle 100 to a predetermined state. If there are multiple devices 110, the non-driving mode state is set for each device 110.

[0022] The following is an example of the settings of the device 110 in the non-driving mode. The state of the high beams in the non-driving mode is off. For example, when the vehicle transitions to the non-driving mode with the high beams on, the vehicle-side control unit 31 turns off the high beams. The state of the low beams in the non-driving mode is off. For example, when the vehicle transitions to the non-driving mode with the low beams on, the vehicle-side control unit 31 turns off the low beams. In this case, the command from the vehicle-side control unit 31 takes priority over the position of the switch on the vehicle 100. In other words, the low beams are turned off even if the switch that operates the low beams is in the ON position.

[0023] In the non-driving mode, the hazard lights are flashing. When the vehicle-side control unit 31 transitions to the non-driving mode, it issues a command to flash the hazard lights. In the non-driving mode, the side mirrors are folded. When the vehicle-side control unit 31 transitions to the non-driving mode, it moves the side mirrors to the stored position. In the non-driving mode, the room lamps are off. When the vehicle-side control unit 31 transitions to the non-driving mode, it turns off the room lamps. In the non-driving mode, the multimedia display is off. When the vehicle-side control unit 31 transitions to the non-driving mode, it turns off the multimedia display, including the navigation system and audio.

[0024] The audio state in the non-driving mode is stopped. When the vehicle-side control unit 31 transitions to the non-driving mode, it stops the audio. The key lock state in the non-driving mode is locked. When the vehicle-side control unit 31 transitions to the non-driving mode, it puts the key lock into the locked state. This makes it impossible to drive the vehicle 100.

[0025] In the non-driving mode, the seat heater is turned off or at a low setting. When the vehicle transitions to the non-driving mode, the vehicle-side control unit 31 turns off the seat heater or reduces the output of the seat heater. In the non-driving mode, the air conditioner is turned off or at a low setting. When the vehicle transitions to the non-driving mode, the vehicle-side control unit 31 turns off the air conditioner or reduces the output of the air conditioner.

[0026] In the non-driving mode, the windows are closed. When the vehicle transitions to the non-driving mode, the vehicle-side control unit 31 closes the windows of the vehicle 100. This prevents theft while the driver is away from the vehicle 100. In the non-driving mode, the lights are OFF. For example, when the vehicle transitions to the non-driving mode with the headlights on, the vehicle-side control unit 31 turns off the headlights. In this case, the command from the vehicle-side control unit 31 takes priority over the position of the switch on the vehicle 100. In other words, the headlights are turned off even if the position of the switch that operates the headlights is ON.

[0027] As described above, the state of device 110 in the non-driving mode may include a state that prevents vehicle 100 from driving, a state that reduces power consumption in vehicle 100, a state that notifies those around that vehicle 100 is stopped, and a state that prevents theft and vandalism.

[0028] When the vehicle transitions from the non-driving mode to the driving mode, the vehicle-side control unit 31 restores the state of the device 110. For example, if the high beams were on before the transition to the non-driving mode, the vehicle-side control unit 31 turns on the high beams when returning to the driving mode. In other words, when transitioning from the driving mode to the non-driving mode, the vehicle-side control unit 31 stores the state of the device 110 in the driving mode. When returning from the non-driving mode to the driving mode, the vehicle-side control unit 31 controls the state of the device 110 to the stored state. This reduces the operational burden on the driver when the driver returns to the vehicle 100.

[0029] The terminal control unit 21 changes the operation mode of the mobile terminal 2 according to the radio wave intensity of the short-range wireless communication received by the communication unit 22. The radio wave intensity is, for example, the received signal strength RSSI (Received Signal Strength Indicator) of the communication unit 22.

[0030] When the radio wave strength is stronger than the threshold, the terminal-side control unit 21 sets the operation mode of the mobile terminal 2 to the riding mode. On the other hand, when the radio wave strength is equal to or less than the threshold, the terminal-side control unit 21 sets the operation mode of the mobile terminal 2 to the non-riding mode. The threshold is, for example, a value that determines whether the mobile terminal 2 is outside the vehicle 100. The threshold may have hysteresis. That is, a first threshold may be used to determine whether the radio wave strength has switched from strong to weak, and a second threshold may be used to determine whether the radio wave strength has switched from weak to strong. The second threshold may be a value that indicates that the radio wave strength is stronger than the first threshold.

[0031] The terminal-side control unit 21 may cooperate with the vehicle-side device 3 in the riding mode. For example, the riding mode may be an operation mode as an input / output device for the vehicle 100. In this case, the mobile terminal 2 displays, for example, an image of input / output to the vehicle 100 on the screen of the mobile terminal 2. The input / output image may include, for example, an image for setting the state of the device 110, or may include a navigation image for route guidance. If the mobile terminal 2 has a navigation system, both the navigation image and the input / output image may be displayed on the screen.

[0032] In the non-riding mode, the portable terminal 2 may display an image different from the image in the riding mode. For example, in the non-riding mode, the portable terminal 2 may not display an image of input / output to / from the vehicle 100. For example, in the non-riding mode, the portable terminal 2 may display an image of input / output to / from the vehicle 100 in a different format from that in the riding mode.

[0033] The vehicle-side control unit 31 and the terminal-side control unit 21 may share the timing for switching the operation mode. For example, either the vehicle-side control unit 31 or the terminal-side control unit 21 may determine the timing for switching the operation mode. When the vehicle-side control unit 31 determines the switching timing, the vehicle-side control unit 31 may send a command to switch the operation mode to the terminal-side control unit 21. When the terminal-side control unit 21 determines the switching timing, the terminal-side control unit 21 may send a command to switch the operation mode to the vehicle-side control unit 31.

[0034] The vehicle 100 may be driven by a worker who collects or delivers packages. In this case, the non-driving mode of the vehicle-side device 3 may be a collection / delivery parking mode, which is a mode when the worker temporarily leaves the vehicle 100 for collection or delivery.

[0035] In the collection and delivery parking mode, the vehicle-side control unit 31 sets devices such as headlights, hazard lights, side mirrors, room lamps, multimedia display, audio, key lock, seat heater, and air conditioner to the collection and delivery parking mode state. When returning from the collection and delivery parking mode to the driving mode, the vehicle-side control unit 31 returns the state of each device to its original state. The delivery worker repeatedly gets in and out of the vehicle at each collection and delivery destination. The control system 1 of this embodiment can reduce the driver's burden of operating the devices 110 when getting in and out of the vehicle.

[0036] The portable terminal 2 may be used by a worker who collects and delivers packages. In this case, the riding mode of the portable terminal 2 may be a travel mode, which is a mode used when the vehicle 100 is moved to each collection and delivery location.

[0037] In the travel mode, the mobile terminal 2 may display a list of delivery destinations and a delivery route. In the travel mode, the mobile terminal 2 may display route guidance to the next delivery location or the next collection location. In the travel mode, the mobile terminal 2 may issue a warning if the mobile terminal 2 has been left behind. For example, the mobile terminal 2 outputs a warning sound if the radio wave intensity is strong when the door of the vehicle 100 is opened. This warning notifies the worker that the mobile terminal 2 has been left behind in the vehicle 100.

[0038] When the portable terminal 2 is used by a worker who collects and delivers packages, the non-riding mode of the portable terminal 2 may be a collection / delivery work mode. The collection / delivery work mode is a mode in which the worker performs collection / delivery work outside the vehicle.

[0039] In the collection and delivery operation mode, the portable terminal 2 may be used as a processing terminal for a worker to perform each process of the collection and delivery operation. For example, the portable terminal 2 may execute a process for a worker to check a package to be delivered in the loading platform of the vehicle 100. In this case, the portable terminal 2 may check the ID attached to the package by reading a code attached to the package with a camera or the like.

[0040] In the collection / delivery operation mode, the mobile terminal 2 may be used for input processing of the delivery status of the package. For example, when delivery of the package is completed, the mobile terminal 2 may display an input screen for the recipient to input a signature. The input signature data may be associated with the delivered package and registered in the server.

[0041] In the collection / delivery operation mode, the mobile terminal 2 may be used for a process of recording the completion of the delivery. For example, when the delivery is completed, the mobile terminal 2 may take an image of the delivered package using a camera. The image of the captured package may be associated with the delivered package and registered in the server.

[0042] In the collection and delivery operation mode, the mobile terminal 2 may be used to handle absences. For example, the worker inputs into the mobile terminal 2 that the delivery recipient was absent and the package could not be delivered. The data on the undelivered package due to absence may be associated with the package that could not be delivered and registered on the server.

[0043] The portable terminal 2 may manage the radio wave strength of wireless communication in multiple stages. For example, the portable terminal 2 may manage the radio wave strength of wireless communication in three stages: strong, medium, and weak. In this case, when the radio wave strength is strong, the operation mode of the portable terminal 2 is set to the travel mode. When the radio wave strength is medium or weak, the operation mode of the portable terminal 2 is set to the collection and delivery mode.

[0044] The collection / delivery operation mode may have multiple sub-modes. The multiple sub-modes include, for example, a package confirmation mode and a status input mode. The package confirmation mode is a mode in which the mobile terminal 2 executes a process for confirming a package to be delivered.

[0045] When the worker parks the vehicle 100 at the delivery location, he or she gets out of the vehicle 100 to check the package. At this time, as shown in Figure 4, the distance L1 between the vehicle-side device 3 and the mobile terminal 2 changes from a short distance to a medium distance. In response to this change in distance L1, the mobile terminal 2 transitions from travel mode to package check mode. In other words, the package check mode is set when the radio wave strength changes from strong to medium.

[0046] In the package confirmation mode, the mobile terminal 2 determines whether the ID of the package read by a camera or the like matches the ID of the package to be delivered next. The mobile terminal 2 may display the determination result on a screen, or may output the determination result by voice or the like. If a delivery method is specified for the confirmed package, the mobile terminal 2 may display the specified method. The mobile terminal 2 displays, for example, whether or not delivery to a designated location is possible, and where the package should be left if it is delivered to a designated location.

[0047] The status input mode is a mode that accepts input of the delivery status of a package. After the worker has confirmed the package to be delivered, he or she takes the package and moves to the delivery destination building or the like. At this time, the distance L1 between the vehicle-side device 3 and the portable terminal 2 changes from a medium distance to a long distance. The portable terminal 2 transitions from the package confirmation mode to the status input mode in response to this change in distance L1. In other words, the status input mode is set when the radio wave strength changes from medium to weak.

[0048] In the status input mode, for example, input of delivery completion, input of leaving at delivery completion, input of absence of the delivery destination, etc. The condition for transitioning to the status input mode may include completion of the package confirmation mode. For example, the mobile terminal 2 may transition to the status input mode on the condition that all packages to be delivered have been confirmed in the package confirmation mode. The mobile terminal 2 may prohibit transitioning to the status input mode if there is a package to be delivered that has not been confirmed in the package confirmation mode. In this case, the mobile terminal 2 may issue a warning that there are other packages to be delivered.

[0049] When the distance L1 changes from a long distance to a short distance, the mobile terminal 2 transitions from the collection / delivery operation mode to the travel mode. Note that the condition for returning to the travel mode may include completion of the status input mode. For example, the mobile terminal 2 may prohibit transition to the travel mode if there is a package that has been confirmed in the package confirmation mode but whose status has not been input in the status input mode. In this case, the mobile terminal 2 may prompt the worker to input the status of the package.

[0050] When returning from the collection / delivery operation mode to the travel mode, the mobile terminal 2 may set the next delivery location or collection location, which will automatically start route guidance to the next location in the travel mode.

[0051] As described above, the control system 1 of this embodiment includes the vehicle-side device 3 and the control unit 4. The vehicle-side device 3 is mounted on the vehicle 100 and includes a communication unit 32 that communicates wirelessly with the mobile terminal 2. The control unit 4 includes at least one of the vehicle-side control unit 31 and the terminal-side control unit 21. The vehicle-side control unit 31 changes the operation mode of the vehicle-side device 3 depending on the radio wave strength of the wireless communication. The terminal-side control unit 21 changes the operation mode of the mobile terminal 2 depending on the radio wave strength of the wireless communication. The control system 1 of this embodiment can reduce the operational burden on the driver when getting in and out of the vehicle.

[0052] The vehicle-side device 3 of this embodiment is an in-vehicle device that controls devices possessed by the vehicle 100. The control unit 4 includes a vehicle-side control unit 31 that changes the operation mode of the vehicle-side device 3. When the radio wave strength of the wireless communication is strong, the vehicle-side control unit 31 sets the operation mode of the vehicle-side device 3 to a driving mode, and when the radio wave strength of the wireless communication is weak, the vehicle-side control unit 31 sets the operation mode of the vehicle-side device 3 to a non-driving mode. The control system 1 of this embodiment can reduce the burden on the driver of operating the vehicle-side device 3.

[0053] The control unit 4 of this embodiment includes a terminal-side control unit 21 that changes the operation mode of the mobile terminal 2. When the radio wave strength of the wireless communication is strong, the terminal-side control unit 21 sets the operation mode of the mobile terminal 2 to the riding mode, and when the radio wave strength of the wireless communication is weak, the terminal-side control unit 21 sets the operation mode of the mobile terminal 2 to the non-riding mode. The control system 1 of this embodiment can reduce the burden on the driver of operating the mobile terminal 2.

[0054] The riding mode may be an operation mode in which the mobile terminal 2 functions as an input / output device for the vehicle 100. In this case, the mobile terminal 2 can be operated as an input / output device for the vehicle 100 when the radio wave intensity is strong.

[0055] The non-riding mode may be an operation mode in which the mobile terminal 2 functions as a processing terminal for collection and delivery work. In this case, when the driver is outside the vehicle and the radio wave intensity is weak, the mobile terminal 2 can be operated as a processing terminal.

[0056] The vehicle 100 may be driven by a worker who collects garbage and recyclable materials. In this case, the non-driving mode of the vehicle-side device 3 may be a parking mode for collection, which is a mode when the worker temporarily leaves the vehicle 100 to collect the objects. The non-riding mode of the mobile terminal 2 may be a collection operation mode, which is a mode when the worker performs work to collect the objects outside the vehicle.

[0057] The mobile terminal 2 and the vehicle-side device 3 may change the operation mode depending on the state of the vehicle 100 in addition to the radio wave strength. For example, if the vehicle 100 has a door for loading and unloading luggage on its loading platform, the decision to change the operation mode may be made based on the state of the door. The vehicle-side device 3 may transition from the driving mode to the collection and delivery parking mode when the radio wave strength changes from strong to medium and the door for loading and unloading luggage is operated. The door operation in this case may be, for example, an operation to unlock or open the door for loading and unloading luggage. The mobile terminal 2 may transition from the travel mode to the collection and delivery operation mode when the radio wave strength changes from strong to medium and the door for loading and unloading luggage is operated.

[0058] The state of the vehicle 100 used to determine the operation mode may be a state related to the driving state of the vehicle 100, such as the driving speed or the shift position of the vehicle 100. The control system 1 may prohibit a mode change to the non-driving mode or the non-riding mode when the vehicle 100 is in a driving state.

[0059] The conditions for changing the operation mode may be based on the detection results of a seating sensor of the vehicle 100, a sensor for detecting whether a seat belt is fastened, a driver monitor, etc., in addition to the radio wave intensity.

[0060] Vehicle 100 may be a vehicle having at least one of an engine and a traction motor. For example, vehicle 100 may be an electric vehicle or a hybrid electric vehicle. In this case, vehicle-side control unit 31 may set the state of device 110 to reduce power consumption in vehicle 100 in the non-driving mode. Vehicle 100 may be a micro electric vehicle with a passenger capacity of one person. Vehicle 100 may be a two-wheeled vehicle or a three-wheeled vehicle.

[0061] The vehicle-side device 3 is not limited to an in-vehicle device that controls the device 110. The vehicle-side device 3 may be, for example, a navigation system, an ECU that controls the vehicle 100, or other devices mounted on the vehicle 100.

[0062] [Modification of the embodiment] A modified example of the embodiment will be described with reference to Fig. 6 and Fig. 7. Fig. 6 shows a vehicle-side device and a mobile terminal according to the modified example of the embodiment, and Fig. 7 shows a control table of a control system according to the modified example of the embodiment. As shown in Fig. 6, the vehicle-side device 3 according to the modified example is an in-vehicle device having a holding unit 33 for holding a mobile terminal 2.

[0063] The vehicle-side device 3 has a fixing unit 34 fixed to the vehicle 100, a display unit 35, and a holding unit 33. The display unit 35 has a display surface that displays various information, such as driving speed, driving distance, shift position, turn signal, remaining battery charge, brake status, etc.

[0064] The holding unit 33 is a cradle that holds the portable terminal 2. The holding unit 33 is arranged above the display unit 35. The holding unit 33 holds the portable terminal 2 with the display surface 23 of the portable terminal 2 exposed. The portable terminal 2 is inserted into the holding unit 33 from above. The holding unit 33 has a frame that holds the end of the inserted portable terminal 2.

[0065] The holding unit 33 holds the mobile terminal 2 in a predetermined orientation. For example, the holding unit 33 holds the mobile terminal 2 so that the inclination angle of the display surface 23 is equal to the inclination angle of the screen of the display unit 35. In the following description, the orientation of the mobile terminal 2 when held by the holding unit 33 is referred to as the "held orientation." The held orientation is an orientation in which the display surface 23 of the mobile terminal 2 is horizontally long.

[0066] Providing the holding unit 33 in the vehicle-side device 3 maximizes the radio wave intensity for communication between the vehicle-side device 3 and the portable terminal 2. This increases the change in radio wave intensity when the portable terminal 2 is taken out of the vehicle 100, improving the accuracy of determining the operation mode based on the radio wave intensity.

[0067] The operation of the control system 1 according to the modified embodiment will be described with reference to FIG. 7. FIG. 7 shows the actions of the driver performing delivery work, the distance L1, the operation of the mobile terminal 2, and the state of the device 110, divided into steps S1 to S8. The distance L1 is divided into four stages: close, medium, far, and farthest. "Near" is the value of the distance L1 when the mobile terminal 2 is held by the holding unit 33, and is, for example, a value of 20 cm or less. "Medium" is the value of the distance L1 when the driver is inside the vehicle 100 while holding the mobile terminal 2, and is, for example, a value greater than 20 cm and less than 1 m. "Far" is the value of the distance L1 when the driver is near the vehicle 100, and is, for example, a value greater than 1 m and less than 2 m. "Farthest" is the value of the distance L1 when the driver is far away from the vehicle 100, and is, for example, a value greater than 2 m.

[0068] In step S1, the driver performing delivery work selects a delivery destination. At this time, the application program of the mobile terminal 2 displays a list of scheduled delivery destinations. The driver holds the mobile terminal 2 in his / her hand in the car and selects a delivery destination from the displayed list. The distance L1 at this time is "medium."

[0069] In step S2, the driver drives the vehicle 100 toward the delivery destination. At this time, the mobile terminal 2 is set in the holding unit 33 of the vehicle-side device 3. Therefore, the distance L1 is "near." The operation mode of the mobile terminal 2 is set to the riding mode. In the riding mode, the mobile terminal 2 displays a navigation screen that provides route guidance to the delivery destination.

[0070] In step S3, the vehicle 100 arrives at the delivery destination. The driver removes the mobile terminal from the holder 33 of the vehicle-side device 3. This changes the distance L1 from "close" to "medium," and the operation mode of the vehicle-side device 3 transitions from driving mode to non-driving mode. The vehicle-side control unit 31 starts flashing the hazard lights, applies the electromagnetic parking brake to turn the brake ON, and sets the shift position of the electronically controlled shift lever to P range. Furthermore, if the vehicle 100 has outward-facing signage, the vehicle-side control unit 31 causes the signage to display "Work in progress."

[0071] In step S4, the driver gets out of the vehicle and removes the package to be delivered from the loading platform. When the driver gets out of the vehicle carrying the mobile terminal 2, the distance L1 becomes "far." This causes the operation mode of the mobile terminal 2 to transition from the riding mode to the non-riding mode. The mobile terminal 2 displays a detailed screen of the package. At this time, the mobile terminal 2 displays information about the package to be delivered and the delivery method on the screen. The driver also captures an image of the two-dimensional code of the package using a camera or the like on the mobile terminal 2 and confirms the package to be delivered. The two-dimensional code is, for example, a QR code (registered trademark). If there are multiple packages to be delivered, the two-dimensional codes are read repeatedly for each of the multiple packages.

[0072] If the mobile terminal 2 is left behind inside the vehicle, the mobile terminal 2 issues a warning that the mobile terminal 2 has been left behind. The warning is executed, for example, by cooperation between the vehicle-side device 3 and the mobile terminal 2. The warning is issued when the door for getting on and off the vehicle 100 is open and the distance L1 is "near."

[0073] In step S4, the vehicle-side control unit 31 turns off the headlamps, turns on the room lamps, turns off the audio / display, turns off the seat heaters, turns off the air conditioner, and unlocks the key lock of the luggage compartment. The room lamps that are turned on are, for example, lamps arranged in the luggage compartment.

[0074] In step S5, the driver heads to the delivery destination to hand over the package. As the driver moves away from the vehicle 100, the distance L1 becomes "farthest." The mobile terminal 2 displays a delivery result registration screen. The driver inputs the delivery result into the mobile terminal 2. If an input indicating that delivery is complete is made, a signature input screen is displayed on the mobile terminal 2. If an input indicating that the delivery destination was absent is made, a registration screen for taking the package back is displayed on the mobile terminal 2. If an input indicating that delivery has been completed is made, a camera screen is displayed to capture an image of the completed delivery.

[0075] In step S5, the vehicle-side control unit 31 turns off the room lamp, locks the key lock of the luggage compartment, and displays "Delivery in progress" on the signage.

[0076] If the vehicle 100 has a tailgate lifter, the mobile terminal 2 may display a warning that the tailgate lifter has been left in its original position. The warning display for the tailgate lifter is executed, for example, by cooperation between the vehicle-side device 3 and the mobile terminal 2. For example, if the distance L1 becomes "farthest" without the tailgate lifter being returned to its initial position or the stored position, the mobile terminal 2 displays a warning that the tailgate lifter has been left in its original position.

[0077] In step S6, the driver returns to the vehicle 100. When the driver approaches the vehicle 100 and the distance L1 becomes "far", the mobile terminal 2 determines whether or not a registration has been forgotten. If none of delivery completion, take-away due to absence, or drop-off completion has been registered on the delivery result registration screen, the mobile terminal 2 warns the driver that a registration has been forgotten.

[0078] In step S6, the vehicle-side control unit 31 determines whether to unlock the key lock of the luggage compartment. This determination is made, for example, through cooperation between the vehicle-side device 3 and the mobile terminal 2. The vehicle-side control unit 31 acquires the delivery result registered in step S5 from the mobile terminal 2. If the acquired delivery result is "taken back due to absence," the vehicle-side control unit 31 unlocks the key lock of the luggage compartment. If the delivery result is "taken back due to absence," the vehicle-side control unit 31 may also turn on the room lamp of the luggage compartment.

[0079] In step S7, the driver returns to the vehicle and selects the next delivery destination. When the driver returns to the vehicle, the distance L1 changes from "far" to "medium," and the mobile terminal 2 returns to the riding mode. The mobile terminal 2 displays a list of delivery destinations to prompt the driver to select the next delivery destination.

[0080] In step S7, the vehicle-side control unit 31 returns the operation mode of the vehicle-side device 3 to the driving mode. The vehicle-side control unit 31 returns the state of the headlights to their original state. For example, if the headlights that were on until then were automatically turned off in step S4, the headlights are turned on. Similarly, the vehicle-side control unit 31 returns the states of the audio / display, seat heaters, and air conditioner to the states before they were changed in step S4. If the key lock of the luggage compartment is unlocked in step S6, the vehicle-side control unit 31 locks the key lock in step S7. That is, if the delivery result registered in step S5 is "taken home due to absence," the vehicle-side control unit 31 automatically locks the key lock when the driver gets in the vehicle. If the delivery result is "taken home due to absence," the vehicle-side control unit 31 may also turn off the room lamp in the luggage compartment.

[0081] In step S8, the driver sets the mobile terminal 2 in the holder 33 of the vehicle-side device 3 and drives the vehicle 100 toward the next delivery destination. The distance L1 becomes "near," and the mobile terminal 2 displays the navigation screen. The route guided at this time is the driving route to the delivery destination selected in step S7. Note that when the distance L1 becomes "near," the mobile terminal 2 may display a warning that the tailgate lifter has been forgotten to be returned. In this case, the mobile terminal 2 can display the warning before the driver starts driving.

[0082] In step S8, the vehicle-side control unit 31 stops the flashing of the hazard lamps and turns off the signage. The processes from step S3 to step S8 are repeatedly executed while the next delivery destination is set.

[0083] As described above, the non-riding mode according to the modified embodiment includes multiple sub-modes. The operation mode of the portable terminal 2 in step S4 is the baggage confirmation mode. The operation mode of the portable terminal 2 in step S5 is the status input mode. The operation mode of the portable terminal 2 in step S6 is the forgotten registration confirmation mode.

[0084] The non-traveling mode according to the modified embodiment includes multiple sub-modes. The operation mode of the vehicle-side device 3 in step S3 is an arrival transition mode for transitioning the vehicle 100 to a stopped state. The operation mode of the vehicle-side device 3 in step S4 is an opening mode for opening the luggage compartment for removal of the luggage. The operation mode of the vehicle-side device 3 in step S5 is a standby mode for waiting until the delivery work is completed. The operation mode of the vehicle-side device 3 when the delivery destination is absent in step S6 is an acceptance mode for unlocking the luggage compartment to store the luggage.

[0085] The control system 1 in the modified example may determine the operation mode based on the attitude of the portable terminal 2. For example, when the attitude of the portable terminal 2 is the held attitude, the operation mode of the vehicle-side device 3 may be maintained in the running mode. The vehicle-side control unit 31 may allow the operation mode to be changed from the running mode to the non-running mode when the attitude of the portable terminal 2 is different from the held attitude. When the attitude of the portable terminal 2 is the held attitude, the operation mode of the portable terminal 2 may be maintained in the riding mode. The terminal-side control unit 21 may allow the operation mode to be changed from the riding mode to the non-riding mode when the attitude of the portable terminal 2 is different from the held attitude.

[0086] In a modified example, the vehicle-side device 3 may have a sensor that detects whether the portable terminal 2 is held in the holding unit 33. In this case, when the holding unit 33 holds the portable terminal 2, the operation mode of the vehicle-side device 3 may be maintained in the traveling mode. The vehicle-side control unit 31 may permit a change of the operation mode from the traveling mode to the non-traveling mode when the holding unit 33 does not hold the portable terminal 2. The portable terminal 2 acquires information regarding whether the holding unit 33 holds the portable terminal 2 from the vehicle-side device 3. When the holding unit 33 holds the portable terminal 2, the operation mode of the portable terminal 2 may be maintained in the riding mode. The terminal-side control unit 21 may permit a change of the operation mode from the riding mode to the non-riding mode when the holding unit 33 does not hold the portable terminal 2.
