Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile electronic control, and particularly relates to an electric vehicle door control method and device, a storage medium and electronic equipment. BACKGROUND

[0002] During the electric closing process of the electric vehicle door, the resistance of the door closing will begin to increase sharply after the sealing strip of the door begins to contact the side wall. At this time, in order to ensure that the door can be closed smoothly, the anti-pinch setting of the last distance of the door closing is usually cancelled, and the door is closed by the electric lock attraction after being half-locked. The electric door lock attraction is very large, and is usually set to be above 500 N. However, when the electric door is attracted, the gap between the front door and the rear door or the rear door and the rear side wall is often large enough for a finger to be inserted. Therefore, if the electric door pinches the finger at this time, the injury to the passenger will be very large.

[0003] The disclosed related technology is an electric vehicle door control method, system, vehicle, device and product. The scheme is applied to the door lock system of the electric vehicle door. The scheme includes: detecting whether there is a target object between the electric vehicle door and the door frame of the electric vehicle door during the closing process of the electric vehicle door; if the target object exists, controlling the switch of the side door attraction lock of the electric vehicle door to be in a disconnected state within a preset time period. The defect of the present application patent is that a sufficient sensor or camera must be provided to sense the existence of the obstacle between the door and the side wall, which greatly increases the cost of the system scheme.

[0004] Therefore, the electric vehicle door anti-pinch control method in the related technology needs to set a certain number of sensors around the door, which requires high hardware equipment and has poor anti-pinch effect. SUMMARY

[0005] The present application provides an electric vehicle door control method, device, storage medium and electronic equipment to solve the problem of high hardware equipment requirement and poor anti-pinch effect in the prior art electric vehicle door anti-pinch control method. By controlling the electric attraction lock in different time periods and with different forces and prolonging the attraction time, the electric door pinching risk is solved without using additional hardware equipment, which reduces the cost while ensuring good anti-pinch effect and easy implementation.

The character “ / ” generally represents that the associated objects before and after it are in an “or” relationship.

[0046] The following will be described in conjunction with Figures 1-3 The electric vehicle door control method, device, storage medium and electronic equipment of the present application.

[0047] Figure 1 is a flowchart of the electric vehicle door control method of the present application, and the execution subject is an electric vehicle door control device. As Figure 1 shown, the method of the present application includes the following steps:

[0048] Step 110, determining that the electric vehicle door is in a half-locked state.

[0049] Specifically, the common electric latch on the market is a two-stage lock, i.e., the locked state is divided into a half-locked state and a full-locked state; wherein the half-locked state means that the door is closed to have only a small gap with the door frame, and the door lock tongue on the door is engaged with the lock catch on the door frame to be in the half-locked state, at which time the door can be understood as “virtually closed”, but cannot be directly pulled open, and is not in a locked state; the full-locked state means that the door lock tongue on the door is fully engaged with the lock catch on the door frame, at which time the door is in a locked state.

[0050] To detect that the door enters the half-locked state from the unlocked state, the door lock state of the door can be acquired in response to an external detection door closing signal. The existing door closing signal is mainly sent by the user according to the needs, and the common door closing signal sending forms include: the user sends the door closing signal on the mobile phone, or selects on the vehicle control screen, or presses the door closing button on the door handle, etc. To acquire the door lock state of the door, the half-locked signal state of the electric latch needs to be continuously acquired, and when the electric vehicle door control device detects that the received electric latch half-locked signal jumps, it is determined that the electric vehicle door enters the half-locked state from the unlocked state.

[0051] Step 120, controlling the electric latch to be attracted with a first attraction force for a preset time length.

[0052] Specifically, if the electric vehicle door is detected to enter the half-lock state, the electric vehicle door control device controls the electric latching lock to latch for a preset time length with a first latching force. Here, the latching after the electric vehicle door enters the half-lock state is divided into two stages. In the first stage, a smaller latching force, i.e., the first latching force, is used to maintain latching for a longer latching time, i.e., a preset time length. For example, the preset time length is 1.2s. At this time, the door will stop between the half-lock and full-lock positions. Generally, the general reaction time of an adult is 150-300ms. Therefore, if a person's hand is accidentally placed in the door gap when the electric door is in the half-lock state, the latching time of the door lock is set to be relatively long, about 1.2s, and the latching force of the door lock, i.e., the first latching force, is maintained at a relatively small value, which is relatively low in injury to the person's hand, and is sufficient for the passenger to react.

[0053] In step 130, the electric latching lock is controlled to latch with a second latching force until the electric vehicle door enters the full-lock state, wherein the first latching force is smaller than the second latching force.

[0054] Specifically, after the electric vehicle door controller controls the door lock to perform the first-stage latching with the first latching force for the preset time length, the electric vehicle door controller controls the door lock to perform the second-stage latching with a larger latching force, i.e., the second latching force, to ensure that the door can be latched into the full-lock state, until the electric vehicle door controller detects the full-lock signal of the door lock to jump, the electric vehicle door controller stops driving, and the electric vehicle door is closed. Since the first latching force in the first stage is a smaller force, and the second latching force in the second stage is a larger force to ensure that the door can be latched into the full-lock state, the first latching force is smaller than the second latching force.

[0055] The electric vehicle door control method provided by the embodiment of the present application adopts the method of time period division, force degree division, and latching time extension. In the first latching stage, a smaller latching force is used to latch for a longer time, to give the user sufficient reaction time to remove the object that is clamped or will be clamped. Then, in the second latching stage, the latching force is increased to enable the door to be latched smoothly. The electric door clamping hand risk is solved without using additional hardware devices, the cost is reduced, and the anti-clamping effect is good and easy to implement.

[0056] Based on the above embodiment, the control of the electric latching lock to latch with the first latching force for the preset time length specifically includes:

[0057] The PWM signal with the first duty cycle is output to the latching motor, to control the latching motor to drive the electric latching lock to latch with the first latching force for the preset time length.

[0058] The control of the electric latching lock to latch with the second latching force specifically includes:

[0059] output a PWM signal of a second duty cycle to the attraction motor to control the attraction motor to drive the electric attraction lock to attract with a second attraction force, wherein the first duty cycle is less than the second duty cycle.

[0060] Specifically, the electric vehicle door controller adjusts the size of the attraction force by adjusting the driving PWM signal of the attraction motor driving the electric attraction lock. It should be noted that PWM (Pulse Width Modulation) is a pulse width modulator, and the PWM modulator provides a pulse current with adjustable pulse width and certain frequency to the motor. The greater the pulse width, i.e. the greater the duty cycle, the greater the average voltage provided to the motor, and the higher the motor speed; on the contrary, the smaller the pulse width, i.e. the smaller the duty cycle, the smaller the average voltage provided to the motor, and the lower the motor speed. Here, a smaller first attraction force needs to be adjusted, so the electric vehicle door controller needs to control the PWM signal to have a smaller duty cycle, so that the attraction motor of the electric attraction lock has a low speed and a small attraction force. After the first stage of attraction with the first attraction force for a preset time, the electric vehicle door controller controls the attraction motor of the electric attraction lock to output a second attraction force for a larger attraction force. The electric vehicle door controller controls the PWM signal to have a larger duty cycle, so that the attraction motor of the electric attraction lock has a high speed and a large attraction force.

[0061] Based on any of the above embodiments, in the method, the first attraction force is greater than the whole vehicle half-lock force.

[0062] Specifically, in addition to setting the first attraction force to be less than the second attraction force, the first attraction force also needs to be set to be greater than the whole vehicle half-lock force, wherein the whole vehicle half-lock force is the resistance required to close the door when the electric vehicle door is in a half-lock state. The first attraction force is usually set to about 120N and is determined through calibration. During the calibration of the first attraction force, the whole vehicle half-lock force needs to be considered. The size of the attraction force is adjusted by adjusting the duty cycle of the PWM signal, but the adjustment of the size of the attraction force is affected by the whole vehicle half-lock force. Therefore, it is necessary to ensure that the first attraction force is greater than the whole vehicle half-lock force. The whole vehicle half-lock force can be adjusted by the compression load of the sealing strip, the sealing gap, etc. The sealing gap is adjusted by adjusting the lock catch after the door is completed. The lock catch can be adjusted in position, but adjusting the lock catch will affect the surface difference between the door and the side wall. Therefore, the adjustment amount of the lock catch is limited.

[0063] The calibration of the first attraction force includes the following steps: first, in the design stage, through calculation, when the sealing strip is at the upper limit of the engineer's design tolerance and the sealing gap is at the lower limit of the design (the sealing strip is the hardest and the sealing gap is the smallest, and the sealing reaction force in this working condition is the largest), the vehicle half-lock force < 120N; second, after the sample is installed on the vehicle, the limit sample is made to ensure that the actual sample and the design in the limit state both meet the half-lock force < 120N; third, adjust the PWM of the electric door controller, then test the attraction force of different PWM duty cycles to determine the duty cycle corresponding to 120N; fourth, assemble the adjusted controller duty cycle, limit sealing strip and limit sealing gap on the actual vehicle to verify whether the vehicle door can be smoothly attracted under the conditions of flat slope, inclined slope, normal temperature, high temperature and low temperature; fifth, if it can be smoothly attracted, the calibration is completed. If not, the sealing strip definition or the sealing gap needs to be changed to lower the half-lock force; or the PWM is appropriately increased to make the attraction force slightly greater than 120N; then return to the fourth step until the door can be smoothly attracted.

[0064] It should be noted here that the preferred preset time length is 1.2s, because the reaction time of an adult is 150-300ms, and setting the attraction time of the first attraction force to 1.2s can ensure that the passenger has enough reaction time to perform the next operation, which includes quickly pulling out the finger or pressing the inside / outside switch of the vehicle door to interrupt the door attraction.

[0065] Based on any of the above embodiments, the method further includes:

[0066] Continuously acquiring the half-lock signal of the electric attraction lock;

[0067] If the half-lock signal changes, it is determined that the electric vehicle door is in the half-lock state.

[0068] Specifically, the half-lock signal is a simple microswitch signal issued by the door lock; when the door is open, the switch is in an open state. During the closing of the door lock, the door lock card plate acts like a cam and presses the microswitch, so that the switch changes from off to on, and an electric signal is sent to the electric vehicle door controller, which in turn determines that the door has entered the half-lock state (that is, the half-lock signal changes from off to on once). The connection and disconnection of the circuit show the voltage. The half-lock signal changes from low voltage to high voltage during the closing process; during the opening process, the high voltage changes to low voltage, which is completely different signal. Therefore, the jump of the half-lock signal detected here is from low voltage to high voltage. Once the half-lock signal is detected to change from low voltage to high voltage, it is determined that the electric vehicle door enters the half-lock state.

[0069] Based on any of the above embodiments, in the method, the control of the electric latching lock to latch at the second latching force until the electric vehicle door enters a full latching state specifically comprises:

[0070] controlling the electric latching lock to latch at the second latching force, and continuously acquiring a full latching signal of the electric latching lock;

[0071] in response to a change in the full latching signal, controlling the electric latching lock to stop latching.

[0072] Specifically, if there is no hand or other obstacle at the door gap, the controller controls the door lock to perform the second half latching after latching at the first half for a preset time length, i.e., 1.2S, at this time, the controller adjusts the latching force of the vehicle door to the second latching force (preferably 500N) through the PWM duty cycle, to ensure that the vehicle door can be latched into full latching, until the electric vehicle door controller detects that the full latching signal of the door lock jumps, then the electric vehicle door controller stops driving, and the electric vehicle door completes closing.

[0073] Based on any of the above embodiments, the method further comprises:

[0074] continuously acquiring an on-off signal of the vehicle door within the period corresponding to the preset time length;

[0075] in response to a change in the on-off signal, controlling the electric latching lock to stop latching.

[0076] Specifically, in the first stage of latching, the electric vehicle door controller also needs to continuously detect the on-off signal of the vehicle door, once it is found that the on-off signal jumps, it means that the passenger presses the on-off switch to stop latching because of hand clamping or clamping to an obstacle, so the electric vehicle door controller controls the electric latching lock to stop latching.

[0077] The present application solves the above problems by adopting a method of time period division, force degree division and latching time extension for the control of the electric latching lock. Based on any of the above embodiments, the present application further provides a control method for electric vehicle door anti-pinch, the execution subject of which is an electric vehicle door controller, and the method comprises the following steps:

[0078] Step 1: The electric vehicle door controller receives an external instruction to drive the electric door mechanism to execute vehicle door closing, and in the closing process, the electric vehicle door controller detects and acquires the half latching signal state of the electric latching lock in real time.

[0079] Step 2: When the half latching signal of the electric latching lock received by the electric door controller jumps, the electric vehicle door controller controls the electric latching lock to start latching at the first latching force, the latching force of which is set through PWM duty cycle control: whole vehicle half latching force < first latching force, usually the value of the first latching force is set at about 120N, and is determined through calibration.

[0080] Third step: the electric vehicle door controller controls the electric lock to be attracted with a duty ratio of 120N and a long attraction time, such as 1.2S, at this time, the door will stop between the half-lock and full-lock positions. Generally, the reaction speed of an adult is 150-300ms, so if the hand is accidentally placed in the door gap when the electric door is in the half-lock state, the door lock attraction time is set to be long, about 1.2S, and the attraction force of the door lock is small at this time, which is low in injury to the hand, and the passenger can react and perform the next operation.

[0081] Fourth step: if the hand is accidentally placed in the door gap when the electric door is in the half-lock state, the passenger can break the door attraction by pressing the in / out switch of the door, and the door is opened.

[0082] Fifth step: if there is no hand or other obstacle in the door gap, the electric vehicle door controller controls the door lock to be attracted in the first half for 1.2S, and then performs the second half attraction, at this time, the controller adjusts the door attraction force to be greater than 500N through the PWM duty ratio, so as to ensure that the door can be attracted into the full-lock state until the controller detects the full-lock signal jump of the door lock, the controller stops driving, and the electric vehicle door is closed.

[0083] The embodiment of the application adopts the method of time-sharing period, force degree, and long attraction time to control the electric attraction lock, gives the passenger sufficient reaction time when the hand is clamped, adopts two different duty ratios to ensure that the attraction force in the first attraction is not too large to clamp the hand, and adopts the second attraction to increase the attraction force by increasing the duty ratio, so as to ensure that the door is closed. The scheme does not need to use additional hardware devices to solve the electric door clamping risk, and the cost is low and the implementation is convenient.

[0084] The device embodiment of the application is introduced below, which can be used to execute the electric vehicle door control method in the above-mentioned embodiments of the application. For details not disclosed in the device embodiment of the application, please refer to the above-mentioned embodiments of the electric vehicle door control method.

[0085] Based on any of the above-mentioned embodiments, Figure 2 The structure diagram of the electric vehicle door control device provided by the application is shown in the figure. Figure 2 As shown in the figure, the device comprises a determination module 210, a first control module 220, and a second control module 230, wherein,

[0088] The second control module 230 is configured to control the electric attraction lock to be attracted at a second attraction force until the electric vehicle door enters a full lock state, where the first attraction force is less than the second attraction force.

[0089] The electric vehicle door control device provided by the embodiment of the present application uses the method of time period division, force degree division and attraction time extension to control the electric attraction lock. In the first attraction stage, a smaller attraction force is used for a longer time of attraction, so as to give the user sufficient reaction time to remove the object that is clamped or will be clamped. Then, in the second attraction stage, the attraction force is increased to enable the door to be smoothly attracted, so as to realize the electric door clamping risk without using additional hardware devices, reduce the cost, and ensure good anti-clamping effect and convenient implementation.

[0096] continuously acquiring a half lock signal of the electric attraction lock;

[0097] if the half lock signal changes, it is determined that the electric vehicle door is in a half lock state.
