Description

[Technical field]

[0001] The present invention relates to a vehicle safety control device for controlling the opening and closing of a luggage compartment. [Background technology]

[0002] Some vehicles, such as trucks, are provided with a luggage compartment behind the driver's seat for loading luggage. For example, Patent Document 1 discloses a vehicle equipped with a wing-type luggage compartment. In such a wing-type luggage compartment, the wing opens and closes in the vehicle width direction. By opening in the vehicle width direction in this way, the driver or an operator can load and unload luggage from the vehicle width direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-230943 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if the luggage compartment is not completely closed, the driver may not realize it and may continue to drive the vehicle. Also, the luggage compartment opening / closing switch may malfunction due to some kind of impact while the vehicle is moving, causing the luggage compartment to open while the vehicle is moving.

[0005] In view of the above, an object of the present invention is to provide a vehicle safety control device that can prevent the vehicle from traveling with the luggage compartment open. [Means for solving the problem]

[0006] The present invention has been made to solve at least some of the problems described above, and can be realized in the following aspects or application examples.

[0007] (1) The safety control device of the vehicle in this application example includes an opening / closing information acquisition unit that acquires information on whether a cargo compartment of the vehicle is open or closed, a shift operation unit that can select a shift range of the vehicle including a range in which driving power can be transmitted and a range in which driving power cannot be transmitted, a parking brake that applies braking to maintain the vehicle in a parked state, and a control unit that, when information on whether the cargo compartment is open is acquired by the opening / closing information acquisition unit, performs driving prohibition control to prohibit at least one of changing the shift range to a range in which driving power can be transmitted by the shift operation unit and releasing braking by the parking brake.

[0008] In other words, when the luggage compartment is open, the shift operation unit and / or the parking brake are locked to prevent the vehicle from being driven. This makes it possible to prevent the vehicle from being driven with the luggage compartment open.

[0009] (2) In the application example of (1) above, the control unit may mechanically prohibit the shift range selection operation by the shift operation unit as a driving prohibition control that prohibits changing the shift range of the vehicle to a driving power transmittable range. By mechanically prohibiting the shift range selection operation by the shift operation unit in this manner, it is possible to reliably prevent the shift range from being changed and to easily allow the driver to recognize that the shift operation is prohibited.

[0010] (3) In the application example of (1) above, the control unit may invalidate a signal indicating the shift range selected by the shift operation unit as a driving prohibition control for prohibiting the shift operation unit from changing the shift range to a driving power transmittable range. By electrically prohibiting the shift operation unit from selecting the shift range in this manner, it is possible to easily prevent the shift range from being changed.

[0011] (4) In any of the application examples of (1) to (3) above, the vehicle may further include an opening / closing switch that issues an instruction to open or close a luggage compartment of the vehicle, and the control unit may perform an opening prohibition control that prohibits the opening / closing switch from opening the luggage compartment when at least one of the following conditions is satisfied: when the driving power transmittable range is selected by the shift operation unit, and when the parking brake is in a released state. In other words, when the driving power transmittable range is selected or the parking brake is in a released state, the vehicle is in a runnable state, so that by prohibiting the opening of the luggage compartment when in such a state, it is possible to prevent the vehicle from running with the luggage compartment open.

[0012] (5) In the application example of (4) above, a vehicle speed detection unit that detects the vehicle speed of the vehicle may be further provided, and the control unit may perform the open prohibition control even when the vehicle speed detected by the vehicle speed detection unit is equal to or higher than a predetermined vehicle speed. In this way, by determining the vehicle running state from the vehicle speed as well, it is possible to more accurately detect the running of the vehicle and more reliably prevent the vehicle from running with the trunk open.

[0013] (6) In the application example of (4) or (5) above, when the control unit acquires the open information of the luggage compartment by the opening / closing information acquisition unit while the open prohibition control is being executed, the control unit may invalidate the acquired open information. In this way, when the control unit acquires the open information of the luggage compartment despite the execution of the open prohibition control of the luggage compartment, the open information is judged to be a false detection and is invalidated. This makes it possible to prevent malfunctions of other devices based on the open information due to a false detection, and more reliably prevents the vehicle from traveling with the luggage compartment open.

[0014] (7) In any of the application examples described above in (1) to (6), the driving power transmission disabled range may include a neutral range. In this way, in a vehicle in which the driving power transmission disabled range includes the neutral range, it is possible to prevent the vehicle from traveling with the luggage compartment open.

[0015] (8) In any of the application examples described above in (1) to (7), the driving power transmission disabled range may include a parking range. This makes it possible to prevent the vehicle from traveling with the luggage compartment open in a vehicle in which the driving power transmission disabled range includes the parking range.

[0016] (9) In any of the application examples of (1) to (8) above, the luggage compartment may have wings that open and close at least the sides. This makes it possible to prevent a vehicle having wings that open and close the luggage compartment from traveling with the wings 9 open.

[0017] (10) The safety control device of the vehicle in this application example includes an opening / closing switch that issues an instruction to open or close a luggage compartment of the vehicle, a shift operation unit that can select a shift range of the vehicle including a range in which driving power can be transmitted and a range in which driving power cannot be transmitted, a parking brake for maintaining the vehicle in a parked state, and a control unit that performs open prohibition control to prohibit the opening of the luggage compartment by the opening / closing switch when at least one of the following conditions is satisfied: when the driving power transmittable range is selected by the shift operation unit, and when the parking brake is in a released state.

[0018] In other words, when the driving power transmission range is selected or the parking brake is released, the vehicle is in a state in which it can be driven, and by prohibiting the opening of the luggage compartment when the vehicle is in such a state, it is possible to prevent the vehicle from being driven with the luggage compartment open.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, one embodiment of the present invention will be described.

[0021] FIG. 1 shows an overall perspective view of a truck (hereinafter, referred to as a vehicle) according to one embodiment of the present invention.

[0022] The vehicle safety control device of this embodiment is applicable to vehicles equipped with a luggage compartment that can be opened and closed, but here we will explain the case where it is applied to a so-called wing-type truck that has a wing-body type van body (luggage compartment).

[0023] As shown in Fig. 1, the vehicle 1 is a cargo vehicle with a wing body type luggage compartment 3 mounted on the rear of a vehicle body 2. An engine (not shown) is mounted on the front of the vehicle body 2, and a cab 4 including a driver's seat is disposed above the engine.

[0024] The luggage compartment 3 has a rectangular parallelepiped shape that is long in the front-to-rear direction of the vehicle, and has a floor member 5 that forms the floor surface, a front wall 6 that forms the front surface, a rear frame 7 that forms the rear surface, and a double-door rear door 8 that opens and closes the opening formed by the rear frame 7. Furthermore, the luggage compartment 3 has a pair of left and right wings 9 that form the upper and side surfaces, and a flap 10 that forms the lower part of the side surface.

[0025] In the closed state, the wing 9 has an L-shaped cross section, which is made up of a roof portion 9a that corresponds to the left-right half of the upper surface of the luggage compartment 3, and a side wall portion 9b that is from the roof portion 9a to the tailgate 10. In this embodiment, the wings 9 are provided symmetrically, and the following description will be given focusing on the left wing.

[0026] The wing 9 can be opened and closed from the side to the top of the luggage compartment 3 by rotating vertically around a center rail 11 that extends in the front-to-rear direction of the vehicle at the center of the top surface of the luggage compartment 3. The tailgate 10 can also be rotated vertically around the side edge of the floor member 5 as a fulcrum. When the wing 9 is closed and positioned at the upper side in the vehicle height direction, the side of the luggage compartment 3 is closed. The wing 9 may be of a type that opens and closes only on one side in the vehicle width direction.

[0027] The wing 9 is opened and closed by a hydraulic cylinder 21a that connects the front part of the roof part 9a to the upper part of the front wall 6 of the luggage compartment 3, and a hydraulic cylinder 21b that connects the rear part of the roof part 9a to the upper part of the rear frame 7 of the luggage compartment 3. Opening / closing switches 22 that issue commands to open or close the wing 9 are provided on both the left and right sides of the rear frame 7 of the luggage compartment 3.

[0028] The vehicle 1 configured as above is equipped with a safety control device for opening and closing the wing 9 of the luggage compartment. Fig. 2 is a block diagram showing a schematic configuration of the safety control device 31 of this embodiment, and the following description will be given based on this figure.

[0029] The safety control device 31 has, on the body side, an opening / closing switch 22, an opening / closing mechanism 23, an opening / closing control unit 24, and an opening / closing sensor 25 (opening / closing detection unit), with the dashed line shown in Fig. 2 as the boundary. The safety control device 31 also has, on the vehicle side, an ECU 32 (control unit), a shift operation unit 33, a parking brake 34, a vehicle speed sensor 35 (vehicle speed detection unit), a wing opening / closing information acquisition unit 36, and a body control switch 37.

[0030] First, the configuration of the safety control device 31 on the mounting side will be described.

[0031] The opening / closing switch 22 is, for example, a push button switch, and is a pair of an "open" button and a "close" button, and is installed, for example, on the rear frame 7 as shown in FIG. 1. The opening / closing switch 22 constitutes part of the electric circuit of the opening / closing control unit 24, and for example, by continuing to press the "open" button, the DC electric motor operates the hydraulic pump to generate hydraulic pressure, and the hydraulic cylinders 21a, 21b can continue to open the wing 9. Furthermore, by releasing the press of the "open" button, the opening operation of the wing 9 stops. Regarding the closing operation by the "close" button, the opening / closing control unit 24 controls the opening / closing mechanism 23 in response to pressing of the "close" button, thereby closing the wing 9.

[0032] The opening and closing mechanism 23 includes the above-mentioned hydraulic cylinders 21a, 21b, DC electric motor, and hydraulic pump, as well as a battery, an oil tank, valves, and pipes and hoses connecting these.

[0033] The opening / closing control unit 24 is an electric circuit having relays and switches, and is capable of driving a DC electric motor and operating various devices of the hydraulic circuit of the opening / closing mechanism 23 according to the state of the opening / closing switch 22. The opening / closing control unit 24 operates only when a body control switch 37, which will be described later, is in the on state.

[0034] The opening / closing sensor 25 is, for example, a limit switch or a proximity sensor, and is installed, for example, on the wing 9, the front wall 6, the rear frame 7, or the center rail 11, and has a function of detecting the open state of the wing 9. Note that it may detect only the closed state, both the open and closed states, or the opening angle.

[0035] Next, the configuration of the safety control device 31 on the vehicle side will be described.

[0036] The shift operation unit 33 has, for example, a shift lever and is installed near the driver's seat. The shift operation unit 33 allows the driver to select a shift range by changing the position of the shift lever. In this embodiment, the shift range includes a driving power transmittable range consisting of a D (drive) range for forward driving and an R (reverse) range for reverse driving, and a driving power non-transmittable range consisting of an N (neutral) range in which the gear of the transmission is in neutral. In other words, the driving power transmittable range is a shift range in which the power generated by the engine is transmitted to the wheels and the vehicle 1 can move forward or backward, and the driving power non-transmittable range is a shift range in which the power generated by the engine is not transmitted to the wheels. The shift operation unit 33 is electrically connected to the ECU 32 and can transmit shift position information related to the selected shift range to the ECU 32.

[0037] The parking brake 34 is, for example, a wheel parking brake, and has a braking function for maintaining the parked state of the vehicle 1. The operation unit of the parking brake 34 may be a side lever type next to the driver's seat, a foot-operated type, or a switch type.

[0038] The vehicle speed sensor 35 has a function of detecting the speed of the vehicle 1 .

[0039] The wing opening / closing information acquisition unit 36 ​​has a function of acquiring opening / closing information of the wing 9 from the opening / closing sensor 25 on the body side.

[0040] The body control switch 37 is a switch for switching the opening / closing control unit 24 on the body side between an on state and an off state, and the opening / closing control unit 24 can be operated by turning the body control switch 37 on. The body control switch 37 is electrically connected to the ECU 32, and can be switched on and off in response to an instruction from the ECU 32. The body control switch 37 can also be operated manually, for example, by a switch installed near the driver's seat of the cab 4.

[0041] The ECU 32 is a control unit including a central processing unit (CPU), a storage device (ROM, RAM, etc.) for storing a control program, a control map, etc., an input / output device, a timer counter, etc. The ECU 32 can obtain information from various devices and other control units mounted on the vehicle 1 via a CAN (Controller Area Network), which is an in-vehicle communication network, and control various devices based on the obtained information.

[0042] For example, the ECU 32 of this embodiment receives inputs of shift position information from a shift operation unit 33, parking brake on / off information from a parking brake 34, vehicle speed information from a vehicle speed sensor 35, and opening / closing information of the wing 9 from a wing opening / closing information acquisition unit 36. Meanwhile, the ECU 32 can control a shift lock that prohibits the shift operation of the shift operation unit 33, a parking lock that prohibits the operation of the parking brake 34, and on / off switching of a body control switch. In addition, the ECU 32 may also be capable of switching between driving and stopping an engine (not shown), and controlling the gear shifting of a transmission connected to the engine.

[0043] As described above, the ECU 32 of this embodiment is a control unit that mainly monitors the running / stopped state of the vehicle 1 and the open / closed state of the wing 9, and can also control the shift operation unit 33, the parking brake 34, and the body control switch 37. Note that, for the sake of convenience, the ECU 32 is described as one control unit in this embodiment, but it may be composed of multiple ECUs, such as an engine ECU that controls the engine and a transmission ECU that controls the transmission.

[0044] In addition, in this embodiment, the ECU 32 and the wing opening / closing information acquisition unit 36 ​​are described separately, but this is not limited thereto. For example, the ECU 32 may be an integrated unit that also serves the function of the wing opening / closing information acquisition unit 36.

[0045] The ECU 32 of the safety control device 31 of this embodiment can execute a travel prohibition control that does not allow the vehicle 1 to travel while maintaining the key-on state or the engine idling state when the wing 9 is open. Furthermore, the safety control device 31 can execute an open prohibition control that does not open the luggage compartment 3 when the power transmittable range is selected in the shift operation unit 33 or the parking brake 34 is released (off state), i.e., when the vehicle is in a state where it is possible to travel. The travel prohibition control and the open prohibition control will be described in detail below. Note that each control may be implemented independently.

[0046] 3 shows a flowchart illustrating a safety control routine for the wing 9 executed by the ECU 32 of the safety control device 31 according to this embodiment, and the following description will be given along with this flowchart. Note that while the ECU 32 is executing the safety control routine, the engine is maintained in an operating state.

[0047] First, in step S1, the ECU 32 acquires shift position information from the shift operation unit 33 and determines whether or not the currently selected shift range is a driving power transmission disabled range (N range). If the determination result is true (YES), the process proceeds to step S2.

[0048] In step S2, the ECU 32 determines whether or not the parking brake 34 is in an applied state (on state). If the determination result is true (YES), the process proceeds to step S3.

[0049] In step S3, the ECU 32 determines whether the vehicle speed detected by the vehicle speed sensor 35 is less than a predetermined vehicle speed. The predetermined vehicle speed is set to a vehicle speed at which it can be determined that the vehicle 1 is stopped. If the result of this determination is true (YES), the process proceeds to step S4. In other words, if all of the results of the determinations in steps S1 to S3 are true (YES), it can be determined that the vehicle 1 is stopped.

[0050] In step S4, the ECU 32 turns on the body control switch 37. This enables the operation of the opening / closing control unit 24 on the body side.

[0051] Next, in step S5, the ECU 32 acquires the opening / closing information of the wing 9 detected by the opening / closing sensor 25 via the wing opening / closing information acquisition unit 36, and determines whether the wing 9 is "open." If the determination result is true (YES), that is, if the wing 9 is in the open state, the process proceeds to step S6.

[0052] In step S6, the ECU 32 performs a shift change prohibition control that prohibits the shift operation unit 33 from changing to a driving power transmittable range (specifically, D range, R range). Specifically, the ECU 32 performs the shift change prohibition control by mechanically prohibiting the shift range selection operation by the shift operation unit 33. For example, a lock mechanism is provided on the shift lever of the shift operation unit 33, and the lock mechanism is activated to mechanically prohibit the shift range selection operation. Alternatively, if the shift operation unit 33 is electronically controlled, an electrical lock may be performed that invalidates a signal to switch to a driving power transmittable range (D range, R range).

[0053] Next, in step S7, the ECU 32 performs parking brake release prohibition control to prohibit the parking brake 34 from being released. Specifically, the ECU 32 performs the parking brake release prohibition control to mechanically prohibit the braking operation of the parking brake 34. For example, a lock mechanism is provided in an operation section of the parking brake 34, and the operation of the parking brake 34 is mechanically prohibited by activating the lock mechanism. Alternatively, if the parking brake 34 is electronically controlled, an electrical lock may be performed to invalidate a signal to release the parking brake 34.

[0054] Then, in step S8, the ECU 32 determines whether or not the wing 9 is "closed" using the wing opening / closing information acquisition unit 36. If the determination result is false (No), that is, if the wing 9 is still in the open state, the process returns to step S6, and the shift change prohibition control in step S6 and the parking brake release prohibition control in step S7 are maintained.

[0055] On the other hand, if the determination result of step S8 is true (Yes), that is, if the wing 9 is in the closed state, the process proceeds to step S9.

[0056] In step S9, the ECU 32 releases the shift change inhibition control in step S6 and the parking brake release inhibition control in step S7, enables the operation of the shift operating unit 33 and the parking brake 34, and then returns from the routine.

[0057] The above steps S1 to S9 constitute the travel prohibition control by the ECU 32.

[0058] On the other hand, if the shift range is not a driving power transmission impossible range in step S1, i.e., if the shift range is a driving power transmission possible range (D range, R range), the ECU 32 proceeds to step S10. Also, if the parking brake 34 is not in an actuated state in step S2, i.e., if the parking brake 34 is in a released state (off state), the ECU 32 proceeds to step S10. Furthermore, if the vehicle speed detected by the vehicle speed sensor 35 is not less than a predetermined vehicle speed in step S3, i.e., if the vehicle speed is equal to or greater than the predetermined vehicle speed, the ECU 32 proceeds to step S10.

[0059] In step S10, the ECU 32 locks the opening / closing switch 22 via the opening / closing control unit 24. The opening / closing switch 22 is locked, for example, by a mechanical locking mechanism provided in the opening / closing switch 22, or by an electrical lock that invalidates an open signal from the opening / closing switch 22.

[0060] Furthermore, in step S11, the ECU 32 turns off the body control switch 37. This disables the operation of the opening / closing control unit 24 on the body side, and the opening / closing mechanism 23 becomes inoperable.

[0061] In step S12, the ECU 32 judges whether or not the wing opening / closing information acquisition unit 36 ​​has acquired the opening information of the wing 9 from the body-side opening / closing sensor 25. If the judgment result is false (No), the routine is returned. On the other hand, if the judgment result is true (Yes), the process proceeds to step S13.

[0062] In step S13, the ECU 32 detects an open state from the opening / closing sensor 25 on the body side while the vehicle 1 is in a state capable of being driven, the opening / closing switch 22 is locked, and the body control switch 37 is turned off. Since there is a possibility that the opening / closing sensor 25 is making an erroneous detection, the ECU 32 issues an alert to the driver and returns the routine.

[0063] The above steps S1 to S3 and S10 to S13 constitute the release prohibition control by the ECU 32.

[0064] As described above, when the ECU 32 of the safety control device 31 in this embodiment acquires opening information of the luggage compartment 3 from the wing opening / closing information acquisition unit 36 ​​that acquires opening / closing information of the luggage compartment 3 of the vehicle 1, it performs driving prohibition control, which includes shift change prohibition control that prohibits the shift operation unit 33 from changing the shift range to a range in which driving power can be transmitted (D range, R range) and parking brake release prohibition control that prohibits the release of braking by the parking brake 34.

[0065] In other words, when the luggage compartment 3 is open, the shift operation unit 33 and the parking brake 34 are locked to prevent the vehicle 1 from being driven. This makes it possible to prevent the vehicle from being driven with the luggage compartment 3 open. Although the ECU 32 locks the shift operation unit 33 and the parking brake 34, the engine is not stopped, and the engine is kept in an idling state even when the vehicle is stopped. Therefore, various auxiliary devices such as an air conditioner that use engine power can continue to operate.

[0066] Furthermore, in the shift change prohibition control, the ECU 32 mechanically prohibits the selection of a shift range by the shift operation unit 33. Specifically, the selection from a range in which driving power cannot be transmitted to a range in which driving power can be transmitted is mechanically prohibited. By mechanically prohibiting the selection of a shift range by the shift operation unit 33 in this manner, it is possible to reliably prevent a change to a range in which driving power can be transmitted, and to easily allow the driver to recognize that a shift operation is prohibited.

[0067] In addition, in the shift change prohibition control, the ECU 32 may electrically prohibit the shift change by invalidating a signal indicating a shift range corresponding to the shift range selection operation by the shift operating unit 33, thereby making it possible to easily prevent a change to the shift range.

[0068] Furthermore, when at least one of the following conditions is satisfied: when the driving power transmittable range (D range, R range) is selected by the shift operation unit 33, and when the parking brake 34 is in a released state, the ECU 32 performs an opening prohibition control that prohibits the opening of the luggage compartment 3 by the opening / closing switch 22. In other words, when the driving power transmittable range is selected or the parking brake 34 is released, the vehicle 1 is in a runnable state, so by prohibiting the opening of the luggage compartment 3 in such a state, it is possible to prevent the vehicle from running with the luggage compartment 3 open.

[0069] Furthermore, the ECU 32 also performs the open prohibition control when the vehicle speed detected by the vehicle speed sensor 35 is equal to or higher than a predetermined vehicle speed. In this way, by determining the traveling state of the vehicle 1 from the vehicle speed as well, it is possible to more accurately detect the traveling of the vehicle and more reliably prevent the vehicle from traveling with the luggage compartment 3 open.

[0070] Furthermore, when the ECU 32 acquires open information from the open / close sensor 25 by the wing open / close information acquisition unit 36 ​​while the open prohibition control is being executed, the ECU 32 invalidates the acquired open information. The open / close sensor 25 may make a false detection due to vibrations caused by the vehicle traveling. Therefore, when the ECU 32 acquires open information of the luggage compartment 3 despite the execution of the open prohibition control of the luggage compartment 3, the ECU 32 judges the open information to be a false detection and invalidates it, thereby preventing malfunction of other devices based on the open information due to a false detection, and more reliably preventing the vehicle from traveling with the luggage compartment 3 open.

[0071] In the above embodiment, the driving power transmission disabled range includes the N range, so that in a vehicle including the N range, it is possible to prevent the vehicle from traveling with the luggage compartment 3 open. Also, in a vehicle 1 having a wing 9 for opening and closing the luggage compartment 3, it is possible to prevent the vehicle from traveling with the wing 9 open.

[0072] Although the embodiment of the present invention has been described above, the aspects of the present invention are not limited to this embodiment.

[0073] In the above embodiment, the driving power transmittable range is the D (drive) range and the R (reverse) range, and the driving power non-transmittable range is the N (neutral) range, but the driving power transmittable range and the driving power non-transmittable range are not limited to these. For example, the driving power non-transmittable range may include the P (parking) range. This makes it possible to prevent the vehicle from traveling with the luggage compartment 3 open in a vehicle in which the driving power non-transmittable range includes the P range.

[0074] Furthermore, the shift operation unit is not limited to a shift lever such as a floor shift, column shift, or instrument shift, but may be a paddle shift, button type, or dial type.

[0075] In the above embodiment, the opening / closing mechanism 23 of the wing 9 is the hydraulic cylinders 21a, 21b via an electric motor, but the wing opening / closing mechanism is not limited to this, and may be entirely electric actuators or actuators using air pressure. Also, the wing may be manually opened and closed.

[0076] In the above embodiment, the ECU 32 implements both the shift change prohibition control and the parking brake release prohibition control as driving prohibition control when the opening / closing information of the wing 9 is "open." However, the ECU 32 may be configured to perform only one of the controls when the opening / closing information of the wing is "open."

[0077] In addition, the safety control device 31 of the above embodiment has been described as being mounted on a wing-type truck whose luggage compartment 3 has sides that open and close, but the type of vehicle is not limited to this. For example, the safety control device 31 can be applied to the rear door 8 of the luggage compartment 3 of the present embodiment, or the luggage compartment (trunk room) of a passenger car.

[0078] In addition, although the vehicle in the above embodiment is an engine-driven vehicle, the drive source of the vehicle is not limited to an engine, but may be a hybrid vehicle using an engine and a motor as a drive source, or an electric vehicle or a fuel cell vehicle using only a motor as a drive source. In addition, the transmission of the vehicle may be an automatic transmission, or may be a manual transmission, an AMT (automatic manual transmission), a CVT (continuously variable transmission), or the type of the transmission is not limited.

[0079] In addition, vehicles such as electric vehicles and fuel cell vehicles may not have a transmission. In this case, the shift operation unit and the shift range may be parts that move the vehicle forward, backward, or keep the vehicle stationary.

[0080] In the above embodiment, the opening / closing switch 22 for instructing the luggage compartment 3 to be opened or closed is provided on the body side, but it may be provided on the vehicle side. For example, the body control switch 37 may also function as the opening / closing switch for instructing the luggage compartment to be opened or closed.

[0081] In addition, when the shift operating unit is in a driving power transmission range or the parking brake is in a released state (off state) and the cargo compartment is opened, the ECU may automatically switch the shift operating unit to a driving power transmission non-transmittable range and perform shift change prohibition control, or automatically switch the parking brake to a braking state (on state) and perform parking brake release prohibition control.
