  Usually, in the conventional apparatus as described in Patent Document 1, a vehicle state mode (hereinafter referred to as “get-on / off mode”) that allows the vehicle height adjustment when the passenger gets off as described above is prepared, and driving in the passenger compartment is performed. This mode can be switched on / off by switching on / off a switch provided at a place where the user can easily operate.

  By the way, when a vehicle is transported by a ship or the like, it is common to start lashing of the vehicle simultaneously with stopping, and lashing is completed before or immediately after the IG is turned off.

  At this time, if the boarding / alighting mode is on, control for lowering the vehicle height is executed after the completion of the lashing, and the lashing securing the vehicle is loosened.

  Even if the entry / exit mode is turned off at the time of shipment from the factory, the entry / exit mode is turned on when the lashing is completed due to a human error such as a worker who self-propelled to load on the ship accidentally turns on. The possibility remains.

  The present invention has been made to solve such a problem, and a main object of the present invention is to provide a vehicle height adjusting device that prevents the lashing from being loosened during transportation of the vehicle.

  One aspect of the present invention for achieving the above object is a vehicle height adjustment device that lowers the vehicle height of an own vehicle when the IG is turned off in the vehicle, and determines whether or not the own vehicle is being transported. A vehicle height adjustment device comprising: a determination unit that prohibits execution of vehicle height adjustment when the ignition switch is turned off when the determination unit determines that the host vehicle is being transported. is there.

  In the above aspect, the determination means includes, for example, 1) first detection means for detecting whether or not a transportation hook is installed in the own vehicle, and the first detection means is used for transportation to the own vehicle. It may be configured to determine that the host vehicle is being transported when it is detected that the hook is installed, or 2) detect whether or not the dark current cut short pin of the host vehicle has been removed. And a second detecting means configured to determine that the own vehicle is in transit when the second detecting means detects that the dark current cut short pin of the own vehicle has been removed. Or 3) having a third detection means for detecting whether or not a rope is hung on the lashing hook of the own vehicle, and this third detection means can be used as a lashing hook for the own vehicle. When it is detected that the rope has been hung It may be configured to determine that both are in transit.

  Note that in the above aspect, the expression “in transit” is intended to represent a concept including a state immediately before transport that is about to be transported.

  According to the above aspect, when it is determined that the host vehicle is being transported, control for lowering the vehicle height when the passenger gets off is not performed even if the IG is turned off. It is possible to appropriately avoid the occurrence of a situation where the lashing for fixing the vehicle is loosened.

  ADVANTAGE OF THE INVENTION According to this invention, the vehicle height adjustment apparatus which prevented the securing from loosening at the time of vehicle transportation can be provided.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings. The basic concept, main hardware configuration, operating principle, basic control method, and the like of the vehicle height adjusting device are already known to those skilled in the art, and thus detailed description thereof is omitted.

  Hereinafter, a vehicle height adjusting apparatus according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic configuration diagram of a vehicle height adjusting device 100 according to the present embodiment.

  The vehicle height adjusting device 100 determines whether or not the host vehicle is about to be transported or is being transported (hereinafter simply described as “whether or not being transported”). Have

  In the present embodiment, the configuration and logic for determining whether or not the vehicle state determination unit 101 determines that the host vehicle is being transported in any vehicle state may be arbitrary.

  For example, 1) The vehicle state determination unit 101 is provided with means for detecting whether or not a transportation hook is installed in the host vehicle, and the host vehicle is detected when it is detected that the transportation hook is installed in the host vehicle. 2) The vehicle state determination unit 101 may include means for detecting whether or not the dark current cut short pin of the host vehicle has been removed. It may be determined that the host vehicle is being transported when it is detected that the dark current cut short pin has been removed, or 3) the vehicle state determination unit 101 is attached to the locking hook of the host vehicle. Means may be provided for detecting whether the rope is hung or not, and it is determined that the own vehicle is being transported when it is detected that the rope has been hung on the locking hook of the own vehicle. Well or ) 1) above the vehicle by any combination of two or more of to 3) it may be determined whether or not during transport.

  Here, 2) the dark current cut short pin is for comprehensively cutting off the current (dark current) directly supplied from the + terminal of the battery under the IG OFF state for the entire vehicle, In order to prevent battery depletion due to dark current consumption, it is generally removed during vehicle transportation.

  The vehicle height adjusting device 100 further controls the air and oil amount of a suspension (for example, hydraulic type, pneumatic type, etc.) of the own vehicle (not shown) to adjust the vehicle height of the own vehicle. Have The vehicle height adjustment unit 103 may be a known suspension ECU (Electronic Control Unit), or may be an independent dedicated ECU newly provided for the vehicle height adjustment device 100. .

  In this embodiment, the vehicle height adjusting unit 102 is configured to receive IG on / off information and boarding / alighting mode on / off information from a boarding / alighting mode switching switch (not shown).

  The user can permit or disable the execution of the vehicle height adjustment that automatically lowers the vehicle height when the IG is turned off by performing an ON / OFF switching operation on a boarding / alighting mode switching switch (not shown).

  When the IG is turned off when the boarding / alighting mode is ON, the vehicle height adjusting unit 102 lowers the vehicle height of the host vehicle to a height at which the user can easily get off. On the other hand, when the getting-on / off mode is OFF, the vehicle height is not adjusted even if the IG is turned OFF.

  Further, in the present embodiment, when the vehicle state determination unit 101 determines that the host vehicle is being transported, the vehicle height adjustment unit 102 determines that the IG is turned off even if the IG is turned off in the on / off mode ON state. The vehicle height adjustment (that is, control for lowering the vehicle) is not executed when the vehicle is off.

  In other words, in this embodiment, the vehicle state determination unit 101 functions as a means for prohibiting vehicle height adjustment from being executed when the IG is off, triggered by determining that the host vehicle is being transported. become.

  Next, the flow of processing performed by the vehicle height adjusting device 100 when the IG is off will be described with reference to the flowchart of FIG.

  First, when IG OFF is detected (“YES” in S201), the vehicle height adjusting unit 102 confirms whether the getting-on / off mode is ON (S202).

  When the boarding / alighting mode is OFF (“NO” in S202), the user has instructed not to execute the vehicle height adjustment when the IG is off. Execution of vehicle height adjustment, that is, control for lowering the vehicle height to a height at which passengers can easily get off is prohibited (S205).

  On the other hand, when the boarding / alighting mode is ON (“YES” in S202), it is then determined with reference to the determination result by the vehicle state determination unit 101 whether or not the host vehicle is determined to be in transit (S203). ).

  If the host vehicle is not being transported (“NO” in S203), it is determined that the IG is being used normally by the user, and the vehicle height adjustment unit 102 causes the passenger to get off the vehicle height of the host vehicle as usual. Control to lower the height to an easy height is executed (S204).

  On the other hand, when the host vehicle is being transported (“YES” in S203), the vehicle height adjustment unit 102 adjusts the vehicle height when the IG is turned off, that is, the occupant gets off, in order to avoid loosening of the lash Execution of control for lowering the vehicle height to a height that is easy to perform is prohibited (S205).

  As described above, according to the present embodiment, in the vehicle height adjusting device configured to lower the vehicle height of the host vehicle to a height at which the passenger can easily get off when the IG is off, the getting-on / off mode is ON. However, if it is determined that the vehicle is in transit, the vehicle height adjustment is not performed when the IG is off. It is possible to appropriately avoid the occurrence of the situation.

  The present invention can be used for a vehicle height adjusting device. The present invention can be applied regardless of the suspension type such as hydraulic type / pneumatic type, structure, size, shape and the like. Further, the power source type, fuel type, appearance design, weight, size, running performance, etc. of the vehicle to be mounted are not questioned.
