Description

  The present invention relates to a steering lock device that disables steering by fitting a locking means to a steering shaft by a driving force of an actuator.

  In recent years, electronic steering lock devices have been proposed for automobiles (see, for example, Patent Document 1). In this type of steering lock device, the motor is driven and controlled by a steering lock electronic control unit (hereinafter referred to as a steering ECU). The lock bar is engaged with and disengaged from the steering shaft by the rotational driving force of the motor. That is, the lock bar is movable between a position where the lock bar is fitted to the steering shaft (lock position) and a position where the fitting to the steering shaft is released (unlock position).

  Here, a state where the lock bar is fitted to the steering shaft (a state where steering cannot be performed) is referred to as a locked state. On the contrary, a state where the lock bar is not fitted to the steering shaft (a state where steering can be performed) is referred to as an unlocked state. A series of operations from the locked state to the unlocked state is called unlocking operation. On the other hand, a series of operations from the unlocked state to the locked state is called a lock operation.

  When the motor is driven forward from the locked state due to the engine starting operation, the lock bar moves from the locked position to the unlocked position. Then, the unlock state detection switch is turned on by the lock bar, while the lock state detection switch is turned off. As a result, the steering ECU shifts the steering lock device from the locked state to the unlocked state when the unlocked state detection switch is switched from the OFF operation to the ON operation and the lock state detection switch is switched from the ON operation to the OFF operation. Recognizing this, the forward drive of the motor is stopped.

On the other hand, after the engine is stopped, the lock bar moves from the unlock position to the lock position when the on-vehicle door is opened and closed as the vehicle gets off and the motor is driven in reverse from the unlock state. Then, the lock state detection switch is turned on by the lock bar, while the unlock state detection switch is turned off. As a result, the steering ECU shifts the steering lock device from the unlocked state to the locked state when the lock state detection switch is switched from the OFF operation to the ON operation and the unlock state detection switch is switched from the ON operation to the OFF operation. Recognizing this, the reverse drive of the motor is stopped.

According to the invention described in any one of claims 1 to 6, it is possible to improve the credibility of whether or not the normal state has been restored.

Hereinafter, an embodiment in which the present invention is embodied in a steering lock device for an automobile will be described.
As shown in FIG. 1, the steering lock device 1 of the present embodiment is an electronic steering that makes steering impossible by fitting a lock bar 30 to a steering shaft 20 by the rotational driving force of a motor 10. It is a locking device.

First, a schematic configuration of the steering lock device 1 will be described.
As shown in FIG. 1, the steering lock device 1 includes a motor 10, a worm gear 11, a spur gear 12, a lock bar 30, and a steering ECU 40. The motor 10 is a drive source for engaging and disengaging the lock bar 30 with respect to the steering shaft 20. The motor 10 is composed of a DC motor capable of forward rotation and reverse rotation. A worm gear 11 is fixed to the output shaft of the motor 10. A spur gear 12 is engaged with the worm gear 11. The spur gear 12 is engaged with the gear portion 31 of the lock bar 30.

  For this reason, when the motor 10 is rotationally driven, the rotational driving force of the motor 10 is transmitted to the gear portion 31 of the lock bar 30 via the worm gear 11 and the spur gear 12. That is, the rotational motion of the motor 10 is converted into the linear motion of the lock bar 30 by the gear mechanism (worm gear 11, spur gear 12, gear portion 31). Incidentally, the worm gear 11 and the spur gear 12 constitute a speed reduction mechanism that reduces the rotational speed of the driven shaft (the rotational shaft of the spur gear 12) relative to the rotational speed of the main driving shaft (the output shaft of the motor 10).

  Here, when the motor 10 is driven forward by the steering ECU 40 from the locked state due to the engine start operation, the lock bar 30 moves in the direction indicated by the arrow A in FIG. Then, the lock bar 30 is pulled out from the lock groove 21 of the steering shaft 20, and the steering lock device 1 shifts from the locked state to the unlocked state. That is, when the engine start operation is performed, the steering ECU 40 controls the drive of the motor 10 to the unlock side as the unlock operation control (drives the motor 10 in the normal direction).

  On the other hand, when the motor 10 is reversely driven by the steering ECU 40 from the unlocked state due to the opening and closing of the vehicle-mounted door when the vehicle gets off after the engine stops, the lock bar 30 moves in the direction indicated by the arrow B in FIG. Moving. Then, the lock bar 30 is fitted into the lock groove 21 of the steering shaft 20, and the steering lock device 1 shifts from the unlocked state to the locked state. That is, after the engine is stopped, the steering ECU 40 controls the drive of the motor 10 to the lock side (the motor 10 is driven in reverse) as the lock operation control when the vehicle-mounted door is opened and closed as the vehicle gets off.

  In short, the lock bar 30 is located between the position where the lock bar 30 is fitted to the lock groove 21 of the steering shaft 20 (lock position) and the position where the lock groove 30 is released from the lock groove 21 (unlock position). It is movable.

  The steering lock device 1 includes an unlock state detection switch 41 and a lock state detection switch 42. The unlock state detection switch 41 is turned on (switch closed) when the lock bar 30 is moved to the unlock position (when the steering lock device 1 shifts to the unlock state). Then, a signal (H level signal) indicating the transition to the unlocked state is input from the unlocked state detection switch 41 to the steering ECU 40. As a result, the steering ECU 40 recognizes that the transition to the unlocked state has been completed, and the forward driving of the motor 10 is stopped by the steering ECU 40.

  The lock state detection switch 42 is turned on (switch closed) when the lock bar 30 is moved to the lock position (when the steering lock device 1 shifts to the lock state). Then, a signal (H level signal) indicating the transition to the locked state is input from the locked state detection switch 42 to the steering ECU 40. As a result, the steering ECU 40 recognizes that the transition to the locked state is completed, and the steering ECU 40 stops the reverse drive of the motor 10.

Next, the configuration of the steering ECU 40 will be described.
As shown in FIG. 2, the steering ECU 40 includes a microcomputer 60, transistors TR1 and TR2, and relays 70 and 80. The microcomputer 60 is a CPU unit including a CPU, ROM, RAM, timer, counter, and the like. The microcomputer 60 performs various controls with electric power obtained from a vehicle-mounted battery via a DC-DC converter (not shown) or the like.

  Each of the transistors TR1 and TR2 is turned on when an H level signal is input from the microcomputer 60. In the relay 70, when the coil 71 is excited by the ON operation of the transistor TR1, the movable contact 72 is electrically connected to the negative fixed contact 73 from the state where the movable contact 72 is electrically connected to the positive fixed contact 74. It switches to the state where it is electrically connected to. In the relay 80, when the coil 81 is excited by the ON operation of the transistor TR2, the movable contact 82 is electrically connected to the negative fixed contact 83 from the state where the movable contact 82 is positively connected to the positive fixed contact 84. It switches to the state where it is electrically connected to.

The motor 10 is electrically connected between the movable contact 72 of the relay 70 and the movable contact 82 of the relay 80.
During the unlock operation control, the microcomputer 60 outputs an H level signal to the transistor TR1 and outputs an L level signal to the transistor TR2. Then, the transistor TR1 is turned on, while the transistor TR2 is turned off. For this reason, the coil 71 of the relay 70 is excited, while the coil 81 of the relay 80 is demagnetized. As a result, during unlocking operation control, the in-vehicle battery is connected from the plus terminal of the in-vehicle battery via the plus fixed contact 74, the movable contact 72 of the relay 70, the motor 10, the movable contact 82 of the relay 80, and the minus fixed contact 83. Current flows through the negative terminal.

  That is, the path from the positive terminal of the in-vehicle battery to the negative terminal of the in-vehicle battery through the positive fixed contact 74, the movable contact 72 of the relay 70, the motor 10, the movable contact 82 of the relay 80, and the negative fixed contact 83. A power supply path for unlocking operation is configured.

Thus, during the unlocking operation control, the microcomputer 60 drives the motor 10 in the normal direction by turning on only the transistor TR1.
The microcomputer 60 outputs an L level signal to the transistor TR1 and outputs an L level signal to the transistor TR2 when a signal indicating the transition to the unlock state is input from the unlock state detection switch 41 in accordance with the unlock operation control. A level signal is output. Then, the transistor TR1 is turned off, while the transistor TR2 is turned off. For this reason, the coil 71 of the relay 70 is demagnetized, while the coil 81 of the relay 80 is demagnetized. As a result, no current flows through the motor 10. Accordingly, the forward drive of the motor 10 is stopped.

As described above, when the microcomputer 60 recognizes that the transition to the unlocked state is completed, the microcomputer 60 stops the forward drive of the motor 10.
During the lock operation control, the microcomputer 60 outputs an H level signal to the transistor TR2 and outputs an L level signal to the transistor TR1. Then, the transistor TR2 is turned on, while the transistor TR1 is turned off. For this reason, the coil 81 of the relay 80 is excited, while the coil 71 of the relay 70 is demagnetized. As a result, at the time of lock operation control, the negative voltage of the in-vehicle battery is changed from the positive terminal of the in-vehicle battery through the positive fixed contact 84 of the relay 80, the movable contact 82, the motor 10, the movable contact 72 of the relay 70, and the negative fixed contact 73. Current flows through the side terminals.

  That is, the path from the positive terminal of the in-vehicle battery to the negative terminal of the in-vehicle battery via the positive fixed contact 84 of the relay 80, the movable contact 82, the motor 10, the movable contact 72 of the relay 70, and the negative fixed contact 73. A power supply path for locking operation is configured.

As described above, during the lock operation control, the microcomputer 60 drives the motor 10 in the reverse direction by turning on only the transistor TR2.
The microcomputer 60 outputs an L level signal to the transistor TR2 when a signal indicating that the lock state has been shifted is input from the lock state detection switch 42 in accordance with the lock operation control, while an L level signal is output to the transistor TR1. Is output. Then, the transistor TR2 is turned off, while the transistor TR1 is turned off. For this reason, the coil 81 of the relay 80 is demagnetized, while the coil 71 of the relay 70 is demagnetized. As a result, no current flows through the motor 10. Accordingly, the reverse drive of the motor 10 is stopped.

As described above, when the microcomputer 60 recognizes that the shift to the locked state is completed, the microcomputer 60 stops the reverse rotation driving of the motor 10.
Next, the intermediate state will be described with reference to FIGS.

  As shown in FIG. 3C, in the locked state, the lock state detection switch 42 is turned on, while the unlock state detection switch 41 is turned off. When the unlock operation control is performed from the locked state, the lock bar 30 moves in the arrow A direction. Then, as shown in FIG. 3B, the lock state detection switch 42 is switched from the ON operation to the OFF operation, while the unlock state detection switch 41 is maintained in the OFF operation.

  Then, when the unlocking operation control is continuously performed even after the lock state detection switch 42 is switched to the OFF operation, the unlock state detection switch 41 is turned OFF as shown in FIG. On the other hand, the lock state detection switch 42 is maintained in the OFF operation.

  Thus, the process of shifting from the locked state shown in FIG. 3C to the unlocked state shown in FIG. 3A, or conversely, from the unlocked state shown in FIG. 3A to the locked state shown in FIG. In the process of shifting to the state, there is a state where both the unlock state detection switch 41 and the lock state detection switch 42 are turned off. The state shown in FIG. 3B in which the unlock state detection switch 41 and the lock state detection switch 42 are both turned off is referred to as an intermediate state. That is, the intermediate state exists in the process of unlocking operation control. The intermediate state also exists in the process of lock operation control.

  Incidentally, the steering lock device 1 has a state that is neither the unlocked state shown in FIG. 3A, the intermediate state shown in FIG. 3B, or the locked state shown in FIG. That is, the steering lock device 1 has a state where the unlock state detection switch 41 and the lock state detection switch 42 are both ON (abnormal state).

  The cause of the steering lock device 1 being in an abnormal state is that foreign matter is interposed between the lock bar 30 and the unlock state detection switch 41 (lock state detection switch 42). For example, when a foreign object exists between the lock bar 30 and the unlocked state detection switch 41, the lock state detection switch 42 is turned ON by the lock bar 30 in the locked state, while the unlocked state is detected by the foreign object. The detection switch 41 is turned on.

  Another cause of the steering lock device 1 being in an abnormal state is that the unlock state detection switch 41 (lock state detection switch 42) is malfunctioning. For example, when the unlock state detection switch 41 is out of order, in the locked state, the lock state detection switch 42 is turned on by the lock bar 30, while the lock state detection switch 42 is turned on due to the failure.

Next, features of the steering lock device 1 will be described.
As shown in FIG. 2, the steering ECU 40 includes a nonvolatile memory 90. The nonvolatile memory 90 is electrically connected to the microcomputer 60. The nonvolatile memory 90 stores position data indicating the state of the steering lock device 1 (any of an unlocked state, an intermediate state, a locked state, and an abnormal state). The microcomputer 60 recognizes the state of the steering lock device 1 (any of the unlocked state, the intermediate state, the locked state, and the abnormal state) based on the position data stored in the nonvolatile memory 90. Then, after recognizing that the microcomputer 60 is in an abnormal state, the microcomputer 60 indicates that it has returned from the abnormal state to a normal state (either unlocked state or locked state) when a predetermined condition described later is satisfied. recognize. That is, the microcomputer 60 has a function of returning from an abnormal state. Hereinafter, the “return function from the abnormal state” by the microcomputer 60 will be described.

  A display unit 91 is electrically connected to the microcomputer 60. Based on the display control by the microcomputer 60, the display unit 91 displays a message for prompting an operation that becomes a trigger for starting the unlocking operation control and an operation that becomes a trigger for starting the locking operation control. It is for display. When recognizing that the microcomputer 60 is in an abnormal state, the microcomputer 60 causes the display unit 91 to display characters “Please open and close the door” and a picture that specifically shows the opening and closing operation of the vehicle-mounted door. Incidentally, the opening / closing operation of the vehicle-mounted door corresponds to an operation that serves as a trigger for starting the lock operation control.

  The microcomputer 60 performs lock operation control when the vehicle-mounted door is opened and closed by the driver from an abnormal state based on the display content of the display unit 91. When the unlocking state detection switch 41 is turned off and the locking state detection switch 42 is turned on in accordance with the lock operation control (see FIG. 3C), the microcomputer 60 performs normal lock operation control. Recognize that it was completed.

  When the microcomputer 60 recognizes that the lock operation control has been normally completed from the abnormal state, the microcomputer 60 displays a text “please press the engine start switch” and a picture specifically showing the pressing operation of the engine start switch. To display. Incidentally, the pressing operation of the engine start switch corresponds to an operation that becomes a trigger for starting the unlocking operation control.

  The microcomputer 60 performs unlocking operation control when the engine start switch is pressed by the driver based on the display content of the display unit 91. When the unlock state detection switch 41 is turned ON and the lock state detection switch 42 is turned OFF in accordance with the unlock operation control (see FIG. 3A), the microcomputer 60 controls the unlock operation control. Recognizes that has completed successfully.

  The microcomputer 60 recognizes that the steering lock device 1 is in the unlocked state when the lock operation control and the unlock operation control are all normally completed in the order from the abnormal state. That is, the microcomputer 60 recognizes that the abnormal state has returned to the normal state when the lock operation control and the unlock operation control are all normally completed in the order from the abnormal state. Incidentally, the normal completion of the lock operation control and the unlock operation control in order from the abnormal state corresponds to a “predetermined condition” for returning from the abnormal state to the normal state.

As described above, according to the present embodiment, the following operations and effects can be obtained.
(1) From the abnormal state, when both unlock operation control and lock operation control are normally completed, it is recognized that the abnormal state has returned to the normal state. That is, even if only the unlock operation control (lock operation control) is normally completed from the abnormal state, it is not recognized that the device has returned to the unlock state (lock state). Therefore, it is possible to improve the reliability of whether or not the normal state has been restored.

  (2) It is recognized that the steering lock device 1 is in the unlocked state when both of them are normally completed in the order of the lock operation control and the unlock operation control from the abnormal state. For this reason, it is possible to immediately perform control (engine start control) based on the assumption that the vehicle is unlocked. Therefore, it is possible to perform suitable control in accordance with the position of the lock bar 30.

  (3) In the case of an abnormal state, a message that prompts an operation that is a trigger for starting the unlocking operation control and an operation that is a trigger for starting the locking operation control is notified. For this reason, it becomes possible to perform these operations reliably. Therefore, it is possible to quickly return from the abnormal state to the normal state.

In addition, the said embodiment can also be changed and actualized as follows.
-You may omit the structure which displays a message on the display part 91. FIG. In this case, it is uncertain which of the operation to be a trigger for starting the unlocking operation control and the operation to be a trigger for starting the locking operation control to be performed first.

  The microcomputer 60 performs the unlock operation control when an operation that becomes a trigger for starting the unlock operation control from the abnormal state is performed. When the unlock state detection switch 41 is turned ON and the lock state detection switch 42 is turned OFF in accordance with the unlock operation control (see FIG. 3A), the microcomputer 60 controls the unlock operation control. Recognizes that has completed successfully.

  After recognizing that the unlock operation control has been normally completed from the abnormal state, the microcomputer 60 performs the lock operation control when an operation serving as a trigger for starting the lock operation control is performed. When the unlocking state detection switch 41 is turned off and the locking state detection switch 42 is turned on in accordance with the lock operation control (see FIG. 3C), the microcomputer 60 performs normal lock operation control. Recognize that it was completed.

  The microcomputer 60 recognizes that the steering lock device 1 is in the locked state when both of the unlock operation control and the lock operation control are normally completed in the order from the abnormal state. That is, the microcomputer 60 recognizes that the abnormal state has returned to the normal state when both of the unlock operation control and the lock operation control are normally completed in the order from the abnormal state. Incidentally, the normal completion of the unlock operation control and the lock operation control in order from the abnormal state corresponds to a “predetermined condition” for returning from the abnormal state to the normal state.

  Note that the microcomputer 60 recognizes that the abnormal state has returned to the normal state even when they are normally completed in the order of the lock operation control and the unlock operation control (opposite to the above) from the abnormal state. To do. In short, the microcomputer 60 recognizes that when the unlock operation control and the lock operation control are both normally completed from the abnormal state, the microcomputer 60 has returned to the normal state. At this time, the order of the unlock operation control and the lock operation control may be first.

  As described above, the microcomputer 60 recognizes that it has returned from the abnormal state to the normal state when the unlock operation control and the lock operation control are normally completed in the order from the abnormal state. Thereafter, when the driver performs an operation as a trigger for starting the unlock operation control, the microcomputer 60 performs the unlock operation control. When the unlock state detection switch 41 is turned ON and the lock state detection switch 42 is turned OFF in accordance with the unlock operation control (see FIG. 3A), the microcomputer 60 controls the unlock operation control. Recognizes that has completed successfully.

  Thus, when all of them are normally completed in the order of the unlock operation control, the lock operation control, and the unlock operation control from the abnormal state, the microcomputer 60 recognizes that the steering lock device 1 is in the unlock state. For this reason, it is possible to immediately perform control (engine start control) based on the assumption that the vehicle is unlocked. Therefore, it is possible to perform suitable control in accordance with the position of the lock bar 30.
