DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an unlocking system that is mounted on a motorcycle and unlocks a handlebar will be described below with reference to the accompanying drawings.
FIG. 1 is a diagram showing an electrical configuration of the unlocking system 1. The unlocking system 1 mainly includes a key switch 2, an accelerator position sensor module 3, a controller (control device) 4, a lighting device (light emitting device) 5, and a lock device 6.

  The key switch 2 is a switch that activates various devices mounted on the motorcycle. Generally, only a specific key can be inserted into a key insertion opening provided around a handlebar of the motorcycle. Is inserted into the key insertion slot and rotated, the power is turned on, and in this embodiment, current is supplied to the components of the unlocking system 1 and other electrical components mounted on the vehicle.

  The accelerator position sensor module 3 detects the driver's accelerator operation and outputs a detection signal, and is attached so as to cover the outer periphery of the handlebar of the motorcycle. The accelerator position sensor module 3 includes an accelerator grip for performing an accelerator operation by a rotating operation, and a rotation sensor that detects a rotation angle of the accelerator grip and outputs a detection signal in one case body. The rotation sensor may be connected to the accelerator grip via a wire and installed at a place other than the handle bar. The accelerator position sensor module 3 is essentially an operating device used for engine drive control of a motorcycle. In this embodiment, the accelerator position sensor module 3 further has a function of inputting a personal identification number in the unlocking system 1 as will be described later. Is.

  The controller 4 controls the engine of the motorcycle or the release control of the lock release system 1 based on the detection signal from the accelerator position sensor module 3. The controller 4 is mounted at an arbitrary location such as a lower part of a seat of a motorcycle, and has a storage memory for storing a specified personal identification number in the unlocking system 1 therein.

  The lighting device 5 corresponds to a winker installed at an arbitrary position in front of and behind the motorcycle, and originally indicates a traveling direction or a stop, but in this embodiment, it will be described later. Thus, it is also used for input acceptance confirmation of the unlocking system 1. In addition, the lighting device 5 may use a lighting device of an on-vehicle meter, or a dedicated lighting device may be provided.

  The lock device 6 locks the motorcycle in an inoperable state. In the present embodiment, the lock device 6 is locked in a state in which the handlebar is turned to an inoperable degree by an electromagnetic on-off valve or the like. The unlocking system 1 releases the locked state. The locking device 6 may be a device that locks a wheel in addition to a device that locks a handlebar.

  Next, the unlocking method by the unlocking system 1 will be described in detail with reference to the flowchart of FIG.

  First, when the key switch 2 is turned on, power is supplied to each part and the unlocking system 1 is activated. First, the controller 4 clears the count number Count of the reciprocating rotation operation to 0 (Count = 0), and clears the loop count number n to 0 (n = 0) (step S1). Next, the loop process L1 including the process of steps S2 to S13 and including the loop process L2 is started, and the accelerator position determination switch a is cleared to 0 (a = 0) (step S2). Next, a loop process L2 including the processes of steps S3 to S11 is started, and the accelerator position voltage APV is input from the accelerator position sensor module 3 as the detection signal indicating the rotation angle of the accelerator grip (step S3). It is determined whether or not the position voltage APV is equal to or less than a value of 20% (hereinafter also referred to as 20% FS) with respect to the value of the accelerator position voltage APV when the accelerator is fully opened (100%) (APV ≦ 20). % FS) (step S4). When step S4 is “Yes”, the accelerator position determination switch a is set to 1 (a = 1), and when step S4 is “No”, the process proceeds to step S6. Next, the accelerator position voltage APV is newly input (step S6), and the accelerator position voltage when the accelerator position determination switch a is 1 and the input accelerator position voltage APV fully opens the accelerator (100%). It is determined whether or not the value is 80% or more of the APV value (hereinafter also referred to as 80% FS) (a = 1 and APV ≧ 80% FS) (step S7). When step S7 is “Yes”, the accelerator position determination switch a is set to 2 (a = 2), and when step S7 is “No”, the process proceeds to step S9. Next, an accelerator position voltage APV is newly input (step S9), and it is determined whether the accelerator position determination switch a is 2 and the input accelerator position voltage APV is 20% FS or less (a = 2 and APV ≦ 20% FS) (step S10). When step S10 is “Yes”, the count number Count of the reciprocating rotation operation is incremented (Count = Count + 1), and the throttle position determination switch a is cleared to 0 (a = 0) (step S11). . When step S10 is “No”, the process proceeds to step S12. That is, as shown in FIG. 3, the accelerator grip is rotated from the accelerator off to the fully open position (accelerator position voltage APV is changed from 20% FS or less to 80% FS or more), and then returned to the accelerator off vicinity (accelerator position voltage). When the rotation operation is performed again (APV becomes 20% FS or less), it is counted as a reciprocating rotation operation.

  After the process of step S11, if the end condition of the loop process L2 is satisfied, the process proceeds to step S12. If the end condition of the loop process L2 is not satisfied, the process returns to the start position of the loop process L2, and the processes after step S3 are executed again. . The loop process L2 has an end condition that a predetermined time (10 seconds in the present embodiment) has elapsed since the start of the loop process L2. That is, until about 10 seconds have elapsed since the unlocking system 1 is started, the controller 4 counts the reciprocating rotation operation by the loop processing L2.

  When the loop process L2 ends, the controller 4 blinks the lighting device 5 once as an answer back operation indicating that the reciprocating rotation operation is counted (step S12). Next, the count number n of the loop is incremented (n = n + 1), the count number Count of the reciprocating rotation operation is input to the n-digit input code number Ii (n) (Ii (n) = Count), The count number Count is cleared to 0 (Count = 0) (step S13).

  After the process of step S13, if the end condition of the loop process L1 is satisfied, the process proceeds to step S14. If the end condition of the loop process L1 is not satisfied, the process returns to the start position of the loop process L1 and the processes after step S2 are executed again. . In the loop process L1, the loop count number n is a specified number of digits consisting of the number of specified passwords stored in the storage memory of the controller 4 (for example, when the specified password is 4 digits, the specified number of digits is 4). ) Is the end condition. That is, the controller 4 repeatedly calculates the input code number Ii (n) by the loop process L1 until the input code numbers Ii (n) for the specified number of digits are calculated.

  When the loop process L1 is completed, the controller 4 clears the loop count number n to 0 (n = 0), and clears the security code correctness determination switch E to 0 (E = 0) (step S14). Next, the loop process L3 including the processes of steps S15 to S17 is started, and the loop count number n is incremented (n = n + 1) (step S15). Next, it is determined whether or not the n-digit input password Ii (n) matches the n-digit specified password Is (n) stored in the storage memory (Ii (n) = Is (n) (Step S16). If step S16 is “Yes”, the process proceeds to step S18 if the end condition of the loop process L3 is further satisfied, and if the end condition of the loop process L3 is not satisfied, the process returns to the start position of the loop process L3 and step S15 is performed again. The subsequent processing is executed. When step S16 is “No”, 1 is input to the security code correctness determination switch E (step S17). The loop process L3 uses the loop count number n as a predetermined number of digits as a termination condition. That is, the collation is performed until collation of the input code number Ii (n) and the specified code number Is (n) for the specified number of digits is completed.

  When the loop process L3 is completed, the controller 4 determines whether or not the password number correctness determination switch E is 0 (step S18). If the step S18 is “Yes”, the input password number Ii and the specified password number are determined. As the answer-back operation for the coincidence of Is, the lighting device 5 blinks three times (step S19), and when step S18 is “No”, the answer that the input code number Ii does not match the specified code number Is As a back operation, the lighting device 5 is turned on for a predetermined time (in this embodiment, 3 seconds) (step S20), and the process returns to step S1. After the process of step S19, a release signal is transmitted to the lock device 6 to release the lock state (step S21). In the present embodiment, the handle bar can be rotated by the locked state of the lock device 6. Next, a relay of a starter switch (not shown) is turned on to enable engine start (step S22).

  The unlocking system 1 can input the detection signal output from the accelerator position sensor by executing the above processing, and the rotation operation of the accelerator grip based on the detection signal satisfies a predetermined authentication condition. When it is determined that the condition is satisfied, the locked state of the lock device 6 is released. As a result, when the driver operates the accelerator grip essential to the motorcycle to release the locked state of the locking device 6, the locked state is illegally released due to an unauthorized operation of the key cylinder or an unauthorized acquisition of the key or the mobile terminal. The antitheft effect can be improved.

  In addition, by storing a one-digit or more specified personal identification number Is in the storage memory as the authentication condition, the lock can be prevented from being accidentally released, and the security of the lock device 6 can be improved.

  Whether the number of rotations of the accelerator grip is a first threshold value (20% FS in this embodiment) or less as a method of detecting the opening and closing operations of the accelerator grip based on the detection signal. The number of reciprocating rotation operations is determined according to the above determination, whether the second threshold value is higher than the first threshold value (80% FS in the present embodiment) or more, and whether the second threshold value is less than the first threshold value. By calculating, even if noise is generated in the detection signal, it is possible to prevent erroneous input of the count number of the rotation operation by chattering, and it is possible to perform a reliable release operation and improve convenience. Can be made.

  In addition, by calculating the number of rotations of the accelerator grip and causing the lighting device 5 provided in the motorcycle to perform an answer back operation, a reliable operation input can be performed and convenience can be improved. Furthermore, the motorcycle is turned into a motorcycle after it has been determined that the rotation operation of the accelerator grip satisfies the authentication condition (the input code number Ii and the specified code number Is match) and after the determination that the authentication condition is not satisfied. By making the answering apparatus 5 provided with different answer back operations differently, reliable operation input can be performed and convenience can be improved. Note that an acoustic device such as a horn may be used as the device that performs the answer back operation.

  In addition, safety can be ensured by enabling the engine to be started after the locked state of the locking device 6 is released.

  Note that the lock release system 1 may include a password change function for changing a specified password based on the rotation operation of the accelerator grip. Convenience can be improved because the driver can arbitrarily set the password. In the password change function, it is preferable that the security function as the unlocking system 1 can be improved by invalidating the setting to the continuous password whose digits are the same.

  INDUSTRIAL APPLICABILITY The present invention can be widely applied to a vehicle having a handlebar with an accelerator grip in addition to a motorcycle. It is something that can be done.
