Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a control method and device for a vehicle locking mechanism, an electronic device and a vehicle. Background Art

[0002] In the prior art, the child lock and door lock in the vehicle locking mechanism are completely independent, so a separate child lock unlocking and locking switch unit is provided to control the unlocking of the child lock, which is independent of other door lock unlocking controls. However, the use of a separate child lock unlocking switch unit requires more switch units for control, resulting in an increase in the cost and weight of the vehicle.

[0003] At present, the rear door lock has a structure in which the child lock drive unit and the rear door lock drive unit share a common pin, that is, the child lock drive unit and the rear door lock drive unit share a common terminal, so that a child lock switch unit and a door lock switch unit share a switch unit, reducing the number of switch units, thereby reducing normal cost and weight. However, when the target locking mechanism (door lock or child lock) is unlocked or locked, the controller needs to control multiple switch units to simultaneously access the power signal (non-ground signal), and due to product consistency issues and / or differences in installation positions of the switch units, the closing or disconnecting time of multiple switch units is not synchronized, thereby forming a potential difference at both ends of the drive unit of the non-target locking mechanism, so that the travel of the drive unit may accumulate in the unlocking or locking direction. When the travel accumulates to the unlocking or locking threshold, the non-target locking mechanism will be abnormally unlocked or locked. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Figure 1 The schematic diagram of the structure of a vehicle locking mechanism driving system provided by an embodiment of the present invention is as follows. Figure 1 As shown, the vehicle locking mechanism driving system includes: a controller, a child lock relay J1-1, a four-door locking relay J1-2, a four-door unlocking relay J1-3, a child lock motor (including a left child lock motor and a right child lock motor connected in parallel) and a four-door lock motor (including a left front door lock motor, a right front door lock motor, a left rear door lock motor and a right rear door lock motor). Among them, the child lock motor and the four-door lock motor share a pin (i.e., a common end, for example, a negative pin can be shared), the output end of the four-door unlocking relay J1-3 is connected to the common end, the other pin of the child lock motor is connected to the output end of the child lock relay J1-1, and the other pin of the four-door lock motor is connected to the output end of the four-door locking relay J1-2; the controller is respectively connected to the control ends of the child lock relay J1-1, the four-door locking relay J1-2 and the four-door unlocking relay J1-3, and is used to input a drive signal to each relay to control the relay to be attracted or disconnected. Among them, the child lock relay J1-1, the four-door locking relay J1-2 and the four-door unlocking relay J1-3 are all connected to the ground signal when they are disconnected, and the child lock relay J1-1, the four-door locking relay J1-2 and the four-door unlocking relay J1-3 are all connected to the power signal when they are energized.

[0023] Specifically, when the controller receives the four-door unlocking signal, the four-door unlocking relay J1-3 is controlled to be energized, the four-door locking relay J1-2 is disconnected and the child lock relay J1-1 is energized. Thus, the four-door unlocking relay J1-3 and the child lock relay J1-1 are both connected to the power signal, and the four-door locking relay J1-2 is connected to the ground signal. For the unlocking circuit of the four-door lock, the four-door unlocking relay J1-3 is the positive pole, and the four-door locking relay J1-2 is the negative pole. Current flows through the four-door lock motors respectively, so that the four-door locks are unlocked. For the unlocking circuit of the child lock, the four-door unlocking relay J1-3 is the positive pole, and the child lock relay J1-1 is also the positive pole. Therefore, the potential of the circuit is equal everywhere, and there is no current. Therefore, the child lock maintains the original unlocking state, so that the four-door locks are unlocked separately without the child lock being affected by the unlocking of the four-door locks.

[0024] In view of the technical problems pointed out in the background technology, an embodiment of the present invention provides a control method for a vehicle locking mechanism to avoid abnormal unlocking or locking of the locking mechanism. Figure 2The present invention is a flow chart of a control method for a vehicle locking mechanism, which is applicable to unlocking vehicle locking mechanisms such as door locks and child locks. Specifically, the control method for the vehicle locking mechanism can be executed by a control device for the vehicle locking mechanism, which can be implemented in the form of software and / or hardware and can be integrated in the vehicle.

[0025] like Figure 2 As shown, the control method of the vehicle locking mechanism includes the following steps: S110 , in response to a target unlocking signal of the first locking mechanism, acquiring an unlocking state of the second locking mechanism.

[0026] The unlocked state includes a locked state or an unlocked state, and a first driving unit corresponding to the first locking mechanism and a second driving unit corresponding to the second locking mechanism share a common end.

[0027] Exemplarily, the first locking mechanism may be a door lock, and correspondingly, the second locking mechanism may be a child lock. The first locking mechanism may also be a child lock, and correspondingly, the second locking mechanism may be a door lock. The first locking mechanism may also be one of a left child lock and a right child lock, and correspondingly, the second locking mechanism may be another of the left child lock and the right child lock and / or a door lock. This embodiment does not limit the first locking mechanism and the second locking mechanism, which depends on the needs of the entire vehicle. The first drive unit and the second drive unit may both be motors. The target unlocking signal is used to instruct the controller to control the first switch unit to access the power signal (non-ground signal) and control the second switch unit to access the power signal. Optionally, the target unlocking signal may be used to instruct the controller to control the first switch unit and the second switch unit to be attracted. Typically, the target unlocking signal is an unlocking signal, such as a door lock unlocking signal or a child lock unlocking signal.

[0028] In this embodiment, the unlocking state of the second locking mechanism can be stored in the controller and updated in real time. When the controller receives the target unlocking signal of the first locking mechanism, it reads the unlocking state of the second locking mechanism to determine whether the second locking mechanism is currently in the unlocking state or the locking state.

[0029] S120: According to the target unlocking signal, a first drive signal is input to the first switch unit for a first set time period, and a second drive signal is input to the second switch unit corresponding to the second locking mechanism at the same time.

[0030] The output end of the first switch unit is connected to the common end, the first drive signal is used to control the first switch unit to access the power signal, and the second drive signal is used to control the second switch unit to access the power signal.

[0031] In this embodiment, the first switch unit is a switch unit shared by the first locking mechanism and the second locking mechanism, the non-common end of the first drive unit is connected to the output end of the third switch unit corresponding to the first locking mechanism, and the non-common end of the second drive unit is connected to the output end of the second switch unit corresponding to the second locking mechanism. The first switch unit, the first drive unit and the third switch unit form an unlocking loop of the first locking mechanism, and the first switch unit, the second drive unit and the second switch unit form an unlocking loop of the second locking mechanism. The first switch unit, the second switch unit and the third switch unit can all be relays. When the controller inputs a drive signal to the relay, the relay is energized, so that the relay is connected to the power signal, and the relay is the positive pole of the corresponding unlocking loop; when the controller does not input a drive signal to the relay, the relay is disconnected, so that the relay is connected to the ground signal, and the relay is the negative pole of the corresponding unlocking loop. In addition, the first set time length can be a time length threshold for unlocking or locking the first locking mechanism, that is, when the first drive signal input to the first switch unit continues to reach the first set time length, the first drive unit can drive the first locking mechanism to unlock or lock.

[0032] Specifically, after the controller receives the target unlocking signal, the controller inputs the first drive signal to the first switch unit, and simultaneously inputs the second drive signal to the second switch unit, the first switch unit and the second switch unit are both energized, the first switch unit and the second switch unit are both connected to the power signal, the third switch unit remains disconnected, and the third switch unit is connected to the ground signal. In this way, for the unlocking circuit of the first locking mechanism, the first switch unit is the positive pole, the third switch unit is the negative pole, the current flows through the first drive unit, and when the duration reaches the first set duration, the first drive unit drives the first locking mechanism to unlock or lock. As for the unlocking circuit of the second locking mechanism, in the initial stage, the first switch unit is positive and the second switch unit is also positive. At this time, the potential of the circuit is equal everywhere and there is no current, so the second locking mechanism maintains the original unlocking state; in the final stage, and when the second drive signal also continues for the first set time, affected by the non-drive signal (product consistency problem of the switch unit and / or installation position difference), the first switch unit or the second switch unit is disconnected first, at this time, one of the first switch unit and the second switch unit is positive and the other is negative, and the unlocking circuit of the second locking mechanism generates current, which flows through the second drive unit, and the stroke of the second drive unit accumulates in the unlocking or locking direction. When the accumulated stroke does not reach the unlocking or locking threshold, the second locking mechanism maintains the original unlocking state; when the accumulated stroke reaches the unlocking or locking threshold, the unlocking state of the second locking mechanism changes.

[0033] S130 , controlling the second driving signal to continue for a second set time period according to the unlocking state.

[0034] Among them, the second set time length is different from the first set time length. Within the time difference corresponding to the first set time length and the second set time length, the current direction of the compensation current caused by the first drive signal or the second drive signal in the unlocking circuit of the second locking mechanism is the same as the driving current direction corresponding to the unlocking state; the difference between the first set time length and the second set time length is equal to the time difference between the first switch unit and the second switch unit being attracted or disconnected caused by the non-driving signal.

[0035] In this embodiment, the duration of the first drive signal input to the first switch unit by the controller is different from the duration of the second drive signal input to the second switch unit, so as to realize the timing control of the vehicle locking mechanism, and in the final stage, the current direction of the compensation current caused by the first drive signal or the second drive signal in the unlocking circuit of the second locking mechanism is the same as the driving current direction corresponding to the unlocking state. Therefore, it is equivalent to driving the second locking mechanism to perform the action of the original unlocking state, thereby offsetting the action of the second locking mechanism caused by the non-driving signal to perform the opposite action to the original unlocking state, avoiding the accumulation of the stroke of the second drive unit in the opposite direction of the original unlocking state, and thus avoiding the abnormal unlocking or locking of the second locking mechanism.

[0036] In some embodiments, according to the unlocked state, the second drive signal is controlled to last for a second set time period, including: based on the unlocked state being the locked state, controlling the duration of the second drive signal to be the sum of the first set time period and a preset time threshold; based on the unlocked state being the unlocked state, controlling the duration of the second drive signal to be the difference between the first set time period and the preset time threshold.

[0037] Obviously, the preset time threshold is the difference (positive value) between the second set time and the first set time, that is, the time difference between the first switch unit and the second switch unit caused by the non-driving signal. The preset time threshold can be determined according to the driving capability of the controller pin and the maximum difference of the switch unit. Assume that the direction from the first switch unit → the first drive unit → the third switch unit is the unlocking direction of the first locking mechanism, and the direction from the first switch unit → the second drive unit → the second switch unit is the unlocking direction of the second locking mechanism. In an example, assuming that the driving time of the first switch unit and the second switch unit is the same, the second switch unit will be disconnected first, and the unlocking state of the second locking mechanism is the locked state. When the duration of the controller driving the first switch unit and the second switch unit reaches the first set duration, the controller stops driving the first switch unit, the first drive unit drives the first locking mechanism to unlock, and continues to drive the second switch unit for the preset time threshold. At this time, superficially, the first switch unit will be synchronized with the disconnection time of the second switch unit under the influence of the non-driving signal, that is, after the controller stops driving the first switch unit, the first switch unit remains in the attracted state and is disconnected at the same time as the second switch unit. In essence, it is equivalent to that within the time corresponding to the preset time threshold, the electrical signal along the locking direction of the second locking mechanism caused by the second driving signal is offset by the electrical signal along the unlocking direction of the second locking mechanism caused by the non-driving signal. Therefore, there is no current in the unlocking circuit of the second locking mechanism, and the stroke of the second driving unit will not change in the unlocking direction, so that the second locking mechanism will not be abnormally unlocked.

[0038] It should be noted that, assuming that the driving durations of the first switch unit and the second switch unit are the same, the first switch unit will be disconnected first. The electrical signals in the unlocking circuit of the second locking mechanism caused by the driving signal and the non-driving signal are all along the locking direction of the second locking mechanism, and the unlocking state of the second locking mechanism is the locked state. Therefore, the unlocking state of the second locking mechanism is not affected, and the technical solution of the present invention does not need to consider this situation.

[0039] In another example, assuming that the driving durations of the first switch unit and the second switch unit are the same, the first switch unit will be disconnected first, and the unlocking state of the second locking mechanism is the unlocking state. When the duration of the controller driving the first switch unit and the second switch unit reaches the difference between the first set duration and the preset duration threshold, the controller stops driving the second switch unit and continues to drive the first switch unit to reach the first set duration, and the first drive unit drives the first locking mechanism to unlock. At this time, on the surface, the second switch unit will be synchronized with the disconnection time of the first switch unit under the influence of the non-driving signal, that is, after the controller stops driving the second switch unit, the second switch unit remains in the pull-in state and is disconnected at the same time as the first switch unit. In essence, it is equivalent to that within the time corresponding to the preset duration threshold, the electrical signal along the unlocking direction of the second locking mechanism caused by the first drive signal is offset by the electrical signal along the locking direction of the second locking mechanism caused by the non-driving signal. Therefore, there is no current in the unlocking circuit of the second locking mechanism, and the stroke of the second drive unit will not change in the locking direction, so that the second locking mechanism will not be abnormally locked.

[0040] It should also be noted that, assuming that the driving durations of the first switch unit and the second switch unit are the same, the second switch unit will be disconnected first. The electrical signals in the unlocking circuit of the second locking mechanism caused by the driving signal and the non-driving signal are both along the unlocking direction of the second locking mechanism, and the unlocking state of the second locking mechanism is the unlocking state. Therefore, the unlocking state of the second locking mechanism is not affected, and the technical solution of the present invention does not need to consider this situation.

[0041] Based on the above technical solution, in some implementations, the target unlocking signal is a door lock unlocking signal, the first locking mechanism is a door lock, and the second locking mechanism is a child lock.

[0042] Exemplarily, the door locks may include four-door locks (i.e., left front door lock, right front door lock, left rear door lock, and right rear door lock), or may be a driver's door lock (i.e., left front door lock), or may include three-door locks (i.e., right front door lock, left rear door lock, and right rear door lock). The child lock may be a left child lock, or a right child lock, or may include a left child lock and a right child lock. The above door locks and child locks are determined according to the requirements of the vehicle.

[0043] Specifically, in some embodiments, the child lock includes a left child lock and a right child lock, and the second drive unit includes a left child lock drive unit and a right child lock drive unit connected in parallel; according to the unlocked state, the second drive signal is controlled to last for a second set time period, including: based on the unlocked state of the left child lock and / or the unlocked state of the right child lock is a locked state, the duration of the second drive signal is controlled to be the sum of the first set duration and a preset duration threshold; based on the unlocked state of the left child lock and / or the unlocked state of the right child lock is an unlocked state, the duration of the second drive signal is controlled to be the difference between the first set duration and the preset duration threshold.

[0044] For example, continue to refer to Figure 1 , the door lock includes a four-door lock, the left child lock drive unit is a left child lock motor, the right child lock drive unit is a right child lock motor, the first switch unit is a four-door unlock relay J1-3, the second switch unit is a child lock relay J1-1, the third switch unit is a four-door locking relay J1-2, and the second drive unit includes a left front door lock motor, a right front door lock motor, a left rear door lock motor and a right rear door lock motor in parallel. In this embodiment, it is assumed that the first set duration is 300ms and the preset duration threshold is TBD ms. When the child lock is in a locked state, when the controller receives an unlock signal of the four-door lock, the controller simultaneously drives the four-door unlock relay J1-3 and the child lock relay J1-1 to be attracted, and the driving duration of the four-door unlock relay J1-3 is 300ms, and the driving duration of the child lock relay J1-1 is 300ms+TBD ms. In this way, the micro-motion of the lock body caused by the asynchronous attraction / disconnection of the relay is eliminated. When the child lock is in the unlocked state, when the controller receives the unlock signal of the four-door lock, the controller drives the four-door unlock relay J1-3 and the child lock relay J1-1 to be attracted at the same time, and the driving time of the four-door unlock relay J1-3 is 300ms, and the driving time of the child lock relay J1-1 is 300ms-TBD ms. In this way, the micro-motion of the lock body caused by the asynchronous attraction / disconnection of the relay is eliminated.

[0045] In addition, in some embodiments, the child lock includes a left child lock and a right child lock, the second drive unit includes a left child lock drive unit and a right child lock drive unit connected in series, and the series connection point is connected to the common end, the second switch unit includes a left child lock switch unit and a right child lock switch unit, and the second drive signal includes a left child lock drive signal and a right child lock drive signal; according to the unlocked state, the second drive signal is controlled to last for a second set time, including: based on the unlocked state of the left child lock and the unlocked state of the right child lock are both locked states, the duration of the left child lock drive signal and the right child lock drive signal are controlled to be the sum of the first set time and the preset time threshold; based on the unlocked state of the left child lock and the unlocked state of the right child lock are both unlocked Lock state, control the duration of the left child lock drive signal and the right child lock drive signal to be the difference between the first set duration and the preset duration threshold; based on the left child lock's unlocked state being the locked state, and the right child lock's unlocked state being the unlocked state, control the duration of the left child lock drive signal to be the sum of the first set duration and the preset duration threshold, and control the duration of the right child lock drive signal to be the difference between the first set duration and the preset duration threshold; based on the left child lock's unlocked state being the unlocked state, and the right child lock's unlocked state being the locked state, control the duration of the left child lock drive signal to be the difference between the first set duration and the preset duration threshold, and control the duration of the right child lock drive signal to be the sum of the first set duration and the preset duration threshold.

[0046] Exemplary, reference Figure 3 ,and Figure 1 The difference between the structures shown is that Figure 3 The central driver's door lock (i.e., left front door lock), left child lock, and right child lock are all independently controlled to unlock. Accordingly, child lock relay J1-4, driver's door lock relay J1-5, and driver's door unlock relay J1-6 are added. Figure 3As shown, the door lock includes three door locks, the left child lock drive unit is the left child lock motor, the right child lock drive unit is the right child lock motor, the first switch unit is the three-door unlock relay J1-3, the second switch unit includes the child lock relays J1-1 and J1-4, the third switch unit is the three-door locking relay J1-2, and the second drive unit includes the right front door lock motor, the left rear door lock motor and the right rear door lock motor in parallel. In this embodiment, it is assumed that the first setting duration is 300ms and the preset duration threshold is TBD ms. When the left child lock and the right child lock are both in the locked state, when the controller receives the unlock signal of the three-door door lock, the controller simultaneously drives the three-door unlock relay J1-3, the child lock relay J1-1 and the child lock relay J1-4 to be attracted, and the driving duration of the three-door unlock relay J1-3 is 300ms, and the driving duration of the child lock relay J1-1 and the child lock relay J1-4 is 300ms+TBD ms. In this way, the lock body micro-motion caused by relay pull-in / out asynchronism is eliminated. When the left child lock and the right child lock are both in the unlocked state, when the controller receives the unlock signal of the three-door lock, the controller simultaneously drives the three-door unlock relay J1-3, the child lock relay J1-1 and the child lock relay J1-4 to pull in, and the driving duration of the three-door unlock relay J1-3 is 300ms, and the driving duration of the child lock relay J1-1 and the child lock relay J1-4 is 300ms-TBD ms. In this way, the lock body micro-motion caused by relay pull-in / out asynchronism is eliminated. When the left child lock is in the locked state and the right child lock is in the unlocked state, when the controller receives the unlock signal of the three-door lock, the controller drives the three-door unlock relay J1-3, the child lock relay J1-1 and the child lock relay J1-4 to be attracted at the same time, and the driving time of the three-door unlock relay J1-3 is 300ms, the driving time of the child lock relay J1-1 is 300ms+TBD ms, and the driving time of the child lock relay J1-4 is 300ms-TBD ms. In this way, the micro-motion of the lock body caused by the asynchronous attraction / disconnection of the relay is eliminated.

In this way, the micro-motion of the lock body caused by the asynchronous attraction / disconnection of the relay is eliminated.

[0047] It should be noted that the embodiments of the present disclosure are not limited to the above-mentioned main driver's door lock, left child lock and right child lock all individually controlling the unlocking status, but can also be applied to only the main driver's door lock individually controlling the unlocking status (the driving unit of the main driver's door lock can also share the common end mentioned in the present invention to reduce the number of switch units), or only the left child lock and the right child lock individually controlling the unlocking status, etc., depending on the specific needs of the entire vehicle.

[0048] The control method of the vehicle locking mechanism disclosed in the present invention aims at the situation that the driving units of the vehicle locking mechanism share pins. According to the target unlocking signal, the first switch unit is controlled to access the power signal through the first driving signal, and the second switch unit is controlled to access the power signal through the second driving signal, so as to realize the independent unlocking or locking of the first locking mechanism. In addition, according to the unlocking state of the second locking mechanism, the second driving signal is controlled to last for the second set time, so that within the time difference corresponding to the first set time and the second set time, the current direction of the compensation current caused by the first driving signal or the second driving signal in the unlocking circuit of the second locking mechanism is the same as the driving current direction corresponding to the unlocking state, and the difference between the first set time and the second set time is equal to the time difference between the first switch unit and the second switch unit caused by the non-driving signal. Therefore, within the time difference corresponding to the first set time length and the second set time length, under the action of the first drive signal or the second drive signal, the influence of the non-drive signal on the time asynchrony between the switch units is offset, so that the potentials at both ends of the second drive unit corresponding to the second locking mechanism are equal, that is, there is no potential difference at both ends of the second drive unit, thereby avoiding abnormal unlocking or locking of the second locking mechanism.

[0049] In some embodiments, the vehicle locking mechanism includes a door lock and a child lock, the child lock includes a left child lock and a right child lock, the second drive unit includes a left child lock drive unit and a right child lock drive unit connected in parallel; the target unlocking signal is a child lock unlocking signal, the first locking mechanism is a child lock, and the second locking mechanism is a door lock.

[0050] At this time, when the controller receives the target unlocking signal (such as unlocking signal) of the child lock, it inputs the first drive signal to the first switch unit and lasts for the first set time, and simultaneously inputs the second drive signal to the second switch unit corresponding to the door lock, and controls the second drive signal to last for the second set time according to the unlocking state of the door lock. Specifically, based on the unlocking state of the door lock being the locked state, the duration of the second drive signal is controlled to be the sum of the first set time and the preset time threshold; based on the unlocking state of the door lock being the unlocking state, the duration of the second drive signal is controlled to be the difference between the first set time and the preset time threshold. In this way, when the child lock is unlocked or locked, abnormal unlocking or locking of the door lock can be avoided. The control logic of the door lock is similar to the control logic of the child lock in the aforementioned embodiment, and the aforementioned embodiment can be referred to for details.

[0051] It should be noted that since the use scenarios of child lock unlocking are far less than the use scenarios of door lock unlocking, the abnormal travel of the door lock drive unit is usually eliminated by the normal unlocking or locking of the door lock before accumulating to the unlocking or locking threshold. Therefore, when the child lock is unlocked or locked, the controller drives the corresponding switch unit of the door lock (such as Figure 1 The driving time lengths of the four-door locking relay J1-2 and the four-door unlocking relay J1-3 are both the first set time length (such as 300ms).

[0052] In addition, in some embodiments, the vehicle locking mechanism includes a door lock and a child lock, the child lock includes a left child lock and a right child lock, the second drive unit includes a left child lock drive unit and a right child lock drive unit connected in series, and the series point is connected to the common end, and the second switch unit includes a left child lock switch unit and a right child lock switch unit; the target unlocking signal is a child lock unlocking signal, the first locking mechanism is one of the left child lock and the right child lock, the second locking mechanism includes the other of the left child lock and the right child lock, and / or the door lock.

[0053] In this embodiment, for the case where the left child lock and the right child lock are individually unlocked and controlled, when the controller receives the target unlocking signal (such as the unlocking signal) of one of the child locks, it can combine the unlocking state of the other child lock and / or the unlocking state of the door lock to control the drive signal input to the switch unit corresponding to the other child lock and / or the door lock to last for the second set time. Exemplarily, based on the unlocking state of the above-mentioned other child lock being the locked state, the duration of the drive signal input to the other child lock is controlled to be the sum of the first set time and the preset time threshold; based on the unlocking state of the above-mentioned other child lock being the unlocked state, the duration of the drive signal input to the other child lock is controlled to be the difference between the first set time and the preset time threshold. In this way, when one of the child locks is unlocked or locked, the abnormal unlocking or locking of the other child lock can be avoided. In addition, the control logic of the door lock is the same and will not be repeated here.
