The preferred embodiments of the present application will be described in detail below with reference to examples. It should be understood by those skilled in the art that these exemplary embodiments do not imply any limitation to the present application.

As shown in FIGS. 1 and 2 , the parking lock 1 according to the preferred embodiment of the present application includes a base 3 including a top surface 5 and a bottom surface (not shown) opposite to the top surface 5 . The base 3 may be secured to the ground or other surface by means known in the art, such as by bolting, to enable the parking lock 1 to be mounted to the ground or other surface. The base 3 may be made of any suitable material by means known in the art.

The parking lock 1 further includes a rotating shaft 9 including a first end face 9a, a second end face 9b opposite to the first end face 9a, and an outer peripheral face 9c extending between the first end face 9a and the second end face 9b. The shaft 9 is pivotally mounted to the base 3 . Specifically, the base 3 includes two

shaft mounting members

7 a and 7 b for receiving the shaft 9 . The

shaft mounting members

7a and 7b define shaft holes aligned with each other and sized to allow the shaft 9 to pass therethrough (only the shaft hole of the shaft mounting member 7a is shown in Figure 1). The rotating

shaft mounting members

7 a and 7 b include

bearings

11 a and 11 b provided in the corresponding shaft holes for mounting the rotating shaft 9 . When the parking lock 1 is assembled, the shaft 9 is received by the

shaft mounting members

7a and 7b through the

bearings

11a and 11b so as to be pivotally mounted to the base 3 and to be able to follow a first direction about its own pivot axis (as indicated by arrow B in Figures 5, 6, 7E, 7G and 7H) or a second direction opposite to the first direction (as in Figures 4, 7C, 7D, 7F) indicated by the arrow A) pivots.

Although the

bearings

11a and 11b are shown as rolling bearings in Figures 1 and 2, it should be understood that the bearings may also be other suitable bearings known in the art, such as plain bearings, or no bearings. Furthermore, although the

pivot mounting members

7a and 7b are shown in Figures 1 and 2 as two-piece pivot mounting members, it should be understood that the pivot mounting members may also be one-piece, or in other suitable forms. The

shaft mounting members

7a and 7b may be connected to the base 3 by means known in the art.

The parking lock 1 also includes a vehicle blocking member 13, which may be in the form of a blocking lever, a blocking plate or other suitable forms. The vehicle stop member 13 is connected to the shaft 9 by means known in the art, and can be pivoted with the shaft 9 to be in the uppermost position (as shown in FIGS. 3 and 7A ) and the lowermost position (as shown in FIG. 7F ) relative to the base 3 ) pivot between. The vehicle blocking member 13 also has a lowered position (shown in FIGS. 5 and 7E ) between the uppermost position and the lowermost position, how the vehicle blocking member 13 is maintained in this lowered position will be described below in conjunction with other components of the parking lock 1 . The lowest position of the vehicle stop member 13 is slightly lower than the lowered position. The car blocking member 13 can form a barrier to restrict the vehicle from entering the parking space in which the parking lock 1 is installed when in the uppermost position, and under the chassis of the vehicle when in the lowered position to allow the vehicle to enter the parking space in which the parking lock 1 is installed. The vehicle blocking member 13 may also be painted with colors, patterns or characters to serve as a warning and avoid accidental impact.

The parking lock 1 further comprises a deflection member 15 which is arranged to act on the shaft 9 so that the shaft 9 tends to follow a first direction (as described above, as in Figs. 5, 6, 7E, 7G and 7H). As indicated by arrow B) pivots so that the vehicle stop member 13 tends to pivot towards the uppermost position (as shown in FIGS. 3 and 7A ). In the present embodiment, the deflection member 15 is in the form of a torsion spring which is sleeved on the rotating shaft 9 , one end is attached to the base 3 and the other end is attached to the rotating shaft 9 . In this way, the torsion spring acts on the rotating shaft 9 so that the rotating shaft 9 tends to pivot in the first direction, so that the vehicle stop member 13 tends to pivot toward the uppermost position.

The parking lock 1 also includes a human actuating member 17 connected to the shaft 9, which, when actuated by eg a user, is capable of driving the shaft 9 towards a second direction opposite to the first direction (as described above,

eg

4, 7C, 7D, 7F (represented by arrow A in FIG. 7F) pivots against the action of the deflection member 15, so that the vehicle stop member 13 tends to pivot towards the lowest position. In the present embodiment, the human actuating member 17 may be in the form of a pedal which, when stepped on by a user, is capable of driving the shaft 9 to tend to pivot in the second direction against the action of the deflection member 15, so that the The vehicle stop member 13 tends to pivot towards the lowest position (shown in Figure 7F). As shown in Figure 2, the actuation surface of the human actuation member 17 may also be provided with raised features for enhancing friction.

Referring back to FIG. 1 , the parking lock 1 further includes a first pivot restricting member 19 a and a second pivot restricting member 19 b mounted to the base 3 , and a first engagement provided on the shaft 9 to pivot together with the shaft 9 Member 21. The first engagement member 21 is fixed to the rotating shaft 9 by means known in the art to pivot together with the rotating shaft 9 . The first pivot restricting member 19 a and the second pivot restricting member 19 b cooperate with the first engaging member 21 to limit the pivot range of the rotating shaft 9 and thus the pivot range of the vehicle stop member 13 . In the present embodiment, the first pivot restricting member 19a and the second pivot restricting member 19b are in the form of stoppers, and the first engagement member 21 is in the form of a cam and its engagement portion is fixed to the rotation shaft at the first engagement member 21 At 9 o'clock, it protrudes from the outer peripheral surface 9c of the rotating shaft 9. When no external force acts on the human actuating member 17, the action of the deflection member 15 on the shaft 9 causes the shaft 9 to tend to pivot in the first direction. The first pivot restriction member 19a is arranged to engage the first engagement member 21 to block the pivot shaft 9 from pivoting in the first direction. When the human actuating member 17 is actuated, the human actuating member 17 is able to drive the shaft 9 tending to pivot in a second direction opposite to the first direction against the action of the deflection member 15 . The second pivot restriction member 19b is arranged to engage the first engagement member 21 to block the pivot shaft 9 from pivoting in the second direction. In this way, the first pivot restricting member 19 a and the second pivot restricting member 19 b cooperate with the first engaging member 21 to define the pivot range of the rotating shaft 9 and thus the pivot range of the vehicle stop member 13 . The first pivot restricting member 19a and the second pivot restricting member 19b are arranged to define the highest and lowest positions in the pivoting range of the vehicle stop member 13, respectively. When the first pivot restricting member 19a is engaged with the first engagement member 21, the vehicle stop member 13 is at the highest position, and when the second pivot restricting member 19b is engaged with the first engagement member 21, the vehicle stop member 13 is at the lowermost position. It should be understood that the first pivot limiting member 19a, the second pivot limiting member 19b and the first engagement member 21 may also take other suitable forms to achieve the above functions. For example, the first engaging member 21 may be a groove formed in the outer peripheral surface 9c of the rotating shaft 9, and the first pivot restricting member 19a and the second pivot restricting member 19b may be protrusions protruding into the groove.

In the example shown in FIGS. 1 and 2 , a deflection member 15 in the form of a torsion spring is sleeved on the shaft 9 , one end is attached to the base 3 and the other end is attached to a first engagement mounted on the shaft 9 on member 21. It should be understood that the other end of the torsion spring may also be attached to other parts of the rotating shaft 9 .

The parking lock 1 further includes a first trigger 31 a and a second trigger 31 b mounted on the base 3 . In the embodiment shown in Figure 1, the first trigger 31a is mounted to the base 3 by being mounted to the first pivot limiting member 19a, and the second trigger 31b is mounted adjacent to the second pivot limiting member 19b onto base 3. However, it should be understood that other installations are possible.

The first flip-flop 31a and the second flip-flop 31b are configured to be switchable between a triggered state and a reset state. The first trigger 31a is arranged to be triggered when the first engagement member 21 is engaged with the first pivot limiting member 19a and reset when the first engagement member 21 is disengaged from the first pivot limiting member 19a. The second trigger 31b is arranged to be triggered when the first engagement member 21 is engaged with the second pivot limiting member 19b and reset when the first engagement member 21 is disengaged from the second pivot limiting member 19b.

In the illustrated embodiment, the first trigger 31a is a push trigger and has a first trigger head 33a arranged between the first engagement member 21 and the first pivot limiting member 19a is activated (eg, depressed) by the first engagement member 21 when engaged such that the first trigger 31a is activated. Similarly, the second trigger 31b is also a push trigger and has a second trigger head 33b arranged to be first engaged when the first engagement member 21 is engaged with the second pivot limiting member 19b The member 21 is activated so that the second trigger 31b is triggered. In particular, the first trigger head 33a is arranged to protrude at least partially beyond the portion of the first pivot limiting member 19a for engaging with the first engagement member 21 such that the first trigger head 33a is at the first engagement member 21 can be activated (eg, depressed) by the first engagement member 21 when engaged with the first pivot limiting member 19a, and can be reset when the first engagement member 21 is disengaged from the first pivot limiting member 19a. The second trigger head 33b of the second trigger 31b is arranged to protrude at least partially beyond the portion of the second pivot limiting member 19b for engaging with the first engagement member 21 so that the second trigger head 33b is at the first The engagement member 21 can be activated (eg, depressed) by the first engagement member 21 when engaged with the second pivot limiting member 19b, and can be reset when the first engagement member 21 is disengaged from the second pivot limiting member 19b.

It should be understood that the first trigger 31a and the second trigger 31b may also be other types of triggers, such as proximity sensors or Hall effect sensors. For example, where the trigger is a Hall effect sensor, a magnet may be arranged in or on the first engagement member 21, and a Hall circuit may be arranged in the first pivot limiting member 19a and the second pivot limiting member 19b in or above.

The first flip-flop 31a is configured to generate a first signal (or referred to as a "trigger signal", eg, a continuous current or voltage signal) when triggered, and not to generate the first signal when reset, and a second trigger Device 31b is configured to generate a second signal (or referred to as a "trigger signal", eg, a continuous current or voltage signal) when triggered, and not to generate a second signal when reset. As described above, when the first pivot restricting member 19 a is engaged with the first engagement member 21 , the vehicle stop member 13 is located at the highest position, and when the second pivot restricting member 19 b is engaged with the first engagement member 21 , the vehicle stop member 13 is located at the uppermost position lowest position. Therefore, the first signal can be a first signal indicating whether the vehicle blocking member 13 is in the highest position, and the second signal can be a second signal indicating whether the vehicle blocking member 13 is in the lowest position. Specifically, in the case where the first engagement member 21 is disengaged from the first pivot restricting member 19a, the first trigger 31a is not activated and is in the reset state and does not generate the first signal to indicate that the vehicle stop member 13 is not in the position the uppermost position, and with the first engagement member 21 engaged with the first pivot limiting member 19a, the first trigger 31a is activated and generates a first signal to indicate that the vehicle stop member 13 is at the uppermost position. In the case where the first engagement member 21 is disengaged from the second pivot restricting member 19b, the second trigger 31b is not activated and is in the reset state and does not generate the second signal to indicate that the vehicle stop member 13 is not in the lowermost position, and With the first engagement member 21 engaged with the second pivot limiting member 19b, the second trigger 31b is activated and a second signal is generated to indicate that the vehicle stop member 13 is in the lowermost position. In this way, the first signal provided by the first trigger 31a can indicate whether the vehicle stop member 13 is in the uppermost position, and the second signal provided by the second trigger 31b can indicate whether the vehicle stop member 13 is at the lowermost position.

The parking lock 1 further includes a locking and unlocking assembly 23 mounted on the base 3 for locking and unlocking the rotating shaft 9 . The locking and unlocking assembly 23 has a lockable position (FIG. 4, FIG. 7B, FIG. 7C, FIG. 7F and FIG. 7G) and locking position (FIG. 3, FIG. 5, FIG. 6, FIG. 7A, FIG. 7D, FIG. 7E, FIG. 7H) Switch between the deadbolt 25. In some examples, the lock-unlock assembly 23 may have a driver (not specifically shown) to drive the deadbolt 25 to switch between the unlocked and locked positions. The lock-unlock assembly 23 can provide a third signal that can indicate that the lock-unlock assembly 23 is in a locked state or an unlocked state (eg, based on whether the deadbolt 25 is in a locked or unlocked position).

The parking lock 1 further includes a second engagement member 27 provided on the rotary shaft 9 to pivot together with the rotary shaft 9 . In the example shown in the figures, the second engagement member 27 is in the form of a cam, and its first engagement surface 29a and the second engagement surface 29b extend beyond the outer peripheral surface 9c of the rotation shaft 9 when it is disposed on the rotation shaft 9 . The lock-unlock assembly 23 is arranged such that the deadbolt 25 can engage with the second engagement member 27 to block pivoting of the shaft 9 when in the locked position (when the lock-unlock assembly 23 is in the locked state), and in the unlocked position (when the lock-unlock assembly 23 is in the locked state) When the locking and unlocking assembly 23 is in the unlocked state), it does not engage with the second engaging member 27 to allow the rotation shaft 9 to pivot, wherein the locking tongue 25 blocks the rotation shaft 9 from rotating when engaged with the first engaging surface 29a of the second engaging member 27 Pivoting in the second direction prevents the vehicle stop member 13 from pivoting away from the uppermost position, and blocks the pivot shaft 9 from pivoting in the first direction and makes the vehicle stop member 13 when engaged with the second engaging surface 29b of the second engaging member 27 The lowered position between the uppermost position and the lowermost position is held by the deflection member 15 . It should be understood that the second engagement member 27 may also take other suitable forms to achieve the above functions.

The parking lock 1 also includes a control device 35 (schematically represented in FIG. 8 but not specifically shown in FIGS. 1 to 7H ) mounted to the parking lock 1 for controlling the locking and unlocking assembly 23 . The control device 35 is capable of communicating with the locking and unlocking assembly 23 (as represented by the dashed line in FIG. 8 ) and is used to control the locking tongue 25 of the locking and unlocking assembly 23 to switch between the unlocked position and the locked position. The control device 35 can receive the third signal from the locking and unlocking assembly 23, and send a control signal to the locking and unlocking assembly 23 to control the lock tongue 25 to switch between the unlocking position and the locking position, so as to control the locking and unlocking assembly 23 between the locked state and the locked position. Switch between unlocked states.

The control device 35 is capable of communicating with an external device (eg, a user's or administrator's mobile device, such as a smartphone) remotely located at the parking lock 1 to receive control signals (eg, unlocking and locking) from the device , thereby allowing, for example, a user or administrator to control the locking tongue 25 of the locking and unlocking assembly 23 to switch between the unlocked position and the locked position. In some examples, the control device 35 is capable of wireless communication with external devices remotely located at the parking lock 1 . Such wireless communication may be wireless direct, such as via a Bluetooth signal or an infrared signal. Furthermore, this communication may also be wirelessly indirect, such as via a Wi-Fi signal on a network router or a cellular signal via a cellular base station. In other examples, the control device 35 is also capable of wired communication with external devices remotely located at the parking lock 1 , for example via a universal serial bus (USB).

The control device 35 is also capable of communicating with the first flip-flop 31a and the second flip-flop 31b (as indicated by the dashed lines in FIG. 8 ) to receive signals according to the first signal from the first flip-flop 31a and the second flip-flop 31b. The second signal, and the lock tongue 25 is controlled to switch between the unlocking position and the locking position according to the first signal and the second signal. 3 to 6 and 7A to 7H, how the control device 35 controls the lock tongue 25 to be in the unlocked position and the locked position according to the first signal from the first trigger 31a and the second signal from the second trigger 31b will be described in detail below. switch between locations.

3 to 6 and 7A to 7H illustrate an exemplary operating cycle of the parking lock 1 . FIGS. 3 to 6 show the pivoting process of the blocking member 13 of the parking lock 1 shown in FIG. 1 from a perspective perspective. Figures 7A to 7H schematically illustrate the parking lock 1 during pivoting of the parking member 13 of the parking lock 1 from the uppermost position to the lowermost position, then being locked in the lowered position, and then unlocked and pivoted back to the uppermost position 1 between the lock-unlock assembly 23 and the second engagement member 27 and between the first engagement member 21 and the first trigger 31a and the second trigger 31b. In each of Figures 7A to 7H, the shaft 9 in the upper view and the lower view are at the same pivot angle position, the upper view schematically showing the first engagement member 21 and the first trigger 31a and The cooperation relationship between the second triggers 31b, the lower view schematically shows the cooperation relationship between the lock-unlock assembly 23 and the second engagement member 27.

As shown in FIG. 3 and FIG. 7A , the parking lock 1 is in an initial state. At this time, no external force acts on the human actuating member 17 , the rotating shaft 9 tends to pivot along the first direction under the action of the deflecting member 15 , and the first engaging member 21 is engaged with the first pivot restricting member 19 a to block the rotating shaft 9 The pivoting in the first direction keeps the vehicle stop member 13 in the uppermost position. The first trigger head 33a of the first trigger 31a is activated (eg, depressed) by the first engagement member 21 such that the first trigger 31a is in a triggered state and generates the first signal, while the second trigger 31b The flip-flop 33b is not activated, and the second flip-flop 31b is in a reset state without generating the second signal. The locking tongue 25 of the locking and unlocking assembly 23 is in the locking position under the control of the control device 35 to block the pivoting of the rotating shaft 9 in the second direction. The third signal provided by the lock-unlock assembly 23 indicates that the lock-unlock assembly 23 is in a locked state.

In this initial state, if an external force acts on the human actuating member 17 to drive the shaft 9 to pivot in the second direction against the action of the deflection member 15, the first trigger head 33a of the first trigger 31a will engage with the first The member 21 is disengaged, and the locking tongue 25 is engaged with the first engaging surface 29a of the second engaging member 27 and blocks the pivoting of the shaft 9 in the second direction, thereby preventing the vehicle blocking member 13 from pivoting away from the highest position, and preventing The parking element 13 of the parking lock 1 is lowered without permission. At this time, the first flip-flop 31a returns to the reset state to interrupt the first signal, but the second flip-flop 31b is still in the reset state and does not generate the second signal, and the third signal provided by the lock-unlock component 23 indicates the lock-unlock component 23 is locked.

As shown in FIG. 7B , when the control device 35 receives an unlock signal from, for example, an external device, the control device 35 can control the lock-unlock assembly 23 to switch from the locked state to the unlocked state, that is, to make the lock tongue 25 switch from the locked position to the unlocked state Location. At this time, the first flip-flop 31a is still in the triggered state and generates the first signal, while the second flip-flop 31b is still in the reset state and does not generate the second signal, and the third signal provided by the lock-unlock component 23 indicates the lock-unlock component 23 Switch from the locked state to the unlocked state. This state may be referred to as a "lowerable state" of the parking lock 1 . In this lowerable state, if an external force acts on the human actuating member 17 to drive the shaft 9 to pivot in the second direction against the action of the deflecting member 15, the locking tongue 25 will not engage with the second engaging member 27, so that The pivot shaft 9 is allowed to pivot in the second direction, so that the vehicle stop member 13 can pivot toward the lowermost position.

As shown in FIGS. 4 and 7C , the locking tongue 25 is in the unlocked position, the external force acts on the human actuating member 17 and drives the rotating shaft 9 to pivot in the second direction against the action of the deflection member 15 . This state may be referred to as the "lowering state" of the parking lock 1 . The second engagement member 27 pivots with the rotating shaft 9 to pass the locking tongue 25 on the rotational path. During this period, the first flip-flop 31a returns to the reset state to interrupt the first signal, while the second flip-flop 31b is still in the reset state and does not generate the second signal, and the third signal provided by the lock-unlock component 23 indicates the lock-unlock Assembly 23 is in an unlocked state.

As shown in FIG. 7D , when the first engagement member 21 is pivoted with the rotation shaft 9 to be engaged with the second pivot restriction member 19b, the second pivot restriction member 19b blocks the pivoting of the rotation shaft 9 in the second direction, and The vehicle stop member 13 reaches the lowest position. The second trigger head 33b of the second trigger 31b is activated by the first engagement member 21 so that the second trigger 31b is triggered and generates the second signal for the first time, while the first trigger head 33a of the first trigger 31a is not activated, The first flip-flop 31a is still in the reset state and the first signal is still interrupted. The control device 35 receives the second signal from the second trigger 31b, and controls the locking tongue 25 of the locking and unlocking assembly 23 to switch from the unlocking position to the locking position in response to the second signal. The signal instructs the lock-unlock assembly 23 to switch the lock-unlock assembly 23 from the unlocked state to the locked state. This state may be referred to as a "locked state" of the parking lock 1 .

As shown in FIGS. 5 and 7E , when the external force is removed from the human actuating member 17 , the rotating shaft 9 pivots back in the first direction under the action of the deflecting member 15 , so that the vehicle blocking member 13 is moved back toward the The highest position pivots. As the shaft 9 pivots back to an angle that allows the first engagement member 21 to disengage the second trigger head 33b of the second trigger 31b, the locking tongue 25 of the lock-unlock assembly 23 and the second engagement member 27 The second engagement surface 29b engages and blocks the pivot shaft 9 from pivoting back in the first direction, thereby locking the vehicle stop member 13 in the lowered position. This state may be referred to as the "lowered state" of the parking lock 1 . In this lowered state, the first flip-flop 31a is still in the reset state and the first signal is still interrupted, while the second flip-flop 31b returns to the reset state and the second signal is interrupted for the first time, and the third trigger provided by the lock-unlock assembly 23 The signal indicates that the lock-unlock assembly 23 is in a locked state.

When the external force acts on the human actuating member 17 again to drive the rotating shaft 9 to pivot in the second direction against the action of the deflecting member 15, as shown in FIG. 7F, the second trigger head 33b of the second trigger 31b can be moved by the first An engagement member 21 is activated so that the second flip-flop 31b is triggered again and the second signal is generated a second time, while the first flip-flop 31a is still in the reset state and the first signal is still interrupted. The control device 35 receives the second signal from the second trigger 31b for the second time, and controls the lock tongue 25 of the locking and unlocking assembly 23 to switch from the locking position to the unlocking position in response to the second signal, which is provided by the locking and unlocking assembly 23 The third signal of instructs the lock-unlock assembly 23 to switch from the locked state to the unlocked state. This state may be referred to as the "unlocked state" of the parking lock 1 .

As shown in FIG. 7G , the lock tongue 25 is in the unlocked position, and when the external force is removed from the human actuating member 17 , the rotating shaft 9 will pivot back along the first direction under the action of the deflecting member 15 , thereby driving the vehicle The member 13 pivots back towards the uppermost position. The second engagement member 27 can pivot with the shaft 9 to pass the locking tongue 25 on the rotational path. During this time, the second flip-flop 31b returns to the reset state and the second signal is interrupted a second time, the first flip-flop 31a is still in the reset state and the first signal is interrupted, and the third signal provided by the lock-unlock component 23 indicates locking The unlocking assembly 23 is in an unlocked state.

As shown in FIG. 7H, when the first engagement member 21 is pivoted to be engaged with the first pivot restriction member 19a, the first pivot restriction member 19a blocks the pivoting of the rotation shaft 9 in the first direction, and the vehicle stop member 13 returns to the initial highest position. The first trigger head 33 a of the first trigger 31 a is depressed by the first engagement member 21 . The first flip-flop 31a is retriggered and resumes generating the first signal, and the second flip-flop 31b remains in the reset state and the second signal remains interrupted. The control device 35 receives the first signal from the first trigger 31a, and controls the lock tongue 25 of the locking and unlocking assembly 23 to switch from the unlocking position to the locking position in response to the first signal. The third signal provided by the lock-unlock assembly 23 indicates that the lock-unlock assembly 23 is in a locked state. At this time, the parking lock 1 is restored to its initial state.

Some exemplary operation cycles of the parking space lock 1 according to the present application are described above with reference to FIGS. 3 to 7H . The parking space lock 1 sequentially goes through states such as lowering-lowering-locking-unlocking-reset from the initial state. It should be understood, however, that some of the steps may be omitted. For example, when the vehicle blocking member 13 is locked in the lowered position, the control device 35 may also control the locking tongue 25 of the locking and unlocking assembly 23 to switch from the locking position to the unlocking position based on the locking signal from the external device.

The parking lock 1 also includes other components. In some examples, the parking lock 1 may be equipped with an indicator light to indicate its working status. The indicator light can also serve as a warning to avoid accidental bumps.

The monitor 100 includes a signal analysis module 101 . The signal analysis module 101 is configured to monitor the first, second and third signals described above, and to determine the operating state of the parking lock 1 based on the first, second and third signals. As described above, the first signal indicates whether the vehicle blocking member 13 is in the highest position, the second signal indicates whether the vehicle blocking member 13 is in the lowest position, and the third signal indicates whether the locking and unlocking assembly 23 is in a locked state or an unlocked state.

FIG. 9 schematically shows a flowchart of a method for monitoring the state of a parking space lock according to a preferred embodiment of the present application, and the monitor 100 shown in FIG. 8 can implement the method. The method is described below in conjunction with an exemplary operating cycle of the parking lock 1 shown in FIGS. 3-6 and 7A-7H.

Next, at step S3, the signal analysis module 101 continues to monitor the first signal, the second signal and the third signal after determining that the parking lock 1 is in the initial state (step S2). If the signal analysis module 101 detects that the first signal still exists without the second signal and the third signal indicates that the lock-unlock assembly 23 is switched from the locked state to the unlocked state, it is determined that the vehicle blocking member 13 is still in the uppermost position and the parking lock 1 is in the lowerable position state, and go to step S4.

Next, at step S4, the signal analysis module 101 continues to monitor the first signal, the second signal and the third signal after it is determined that the parking space lock 1 is in a downtable state (step S3). If the signal analysis module 101 detects that the first signal is interrupted and there is no second signal and the third signal indicates that the lock-unlock assembly 23 remains unlocked, it is determined that the blocking member 13 is located between the uppermost position and the lowermost position and the parking lock 1 is in a lowering state , and go to step S5.

Next, at step S5, the signal analysis module 101 continues to monitor the first signal, the second signal and the third signal after determining that the parking lock 1 is in the lowering state (step S4). If the signal analysis module 101 monitors the second signal for the first time and the first signal remains interrupted and the third signal indicates that the lock-unlock assembly 23 is switched from the unlocked state to the locked state, it is determined that the vehicle blocking member 13 is in the lowest position and the parking lock 1 is in the parking space lock locked state, and go to step S6.

Next, at step S6, the signal analysis module 101 continues to monitor the first signal, the second signal and the third signal after determining that the parking lock 1 is in the parking lock locked state (step S5). If the signal analysis module 101 detects that the second signal is interrupted for the first time and the first signal remains interrupted and the third signal indicates that the lock-unlock assembly 23 remains in the locked state, it is determined that the blocking member 13 is kept in the lowered position and the parking lock 1 is kept in the lowered position state, and go to step S7.

Next, at step S7, the signal analysis module 101 continues to monitor the first signal, the second signal and the third signal after determining that the parking lock 1 is kept in the lowered state (step S6). If the signal analysis module 101 monitors the second signal for the second time and the first signal remains interrupted and the third signal indicates that the locking and unlocking assembly 23 is switched from the locked state to the unlocked state, it is determined that the vehicle blocking member 13 is located at the lowest position for the second time and the parking space The lock 1 is in the parking lock unlocked state, and goes to step S8.

Next, at step S8, the signal analysis module 101 monitors the first signal, the second signal and the third signal after determining that the parking lock 1 is in the parking lock unlocked state (step S7). If the signal analysis module 101 monitors the first signal for the second time and the second signal is interrupted for the second time and the third signal indicates that the lock-unlock assembly 23 is switched from the unlocked state to the locked state, it is determined that the vehicle blocking member 13 returns to the uppermost position and the parking space is locked 1 returns to the initial state, and returns to step S1.
