Description

Technical Field

[0001] This application belongs to the technical field of vehicles, and particularly relates to a method and device for controlling a vehicle door and a vehicle. Background Art

[0002] With the large-scale market launch of automated and intelligent vehicles, vehicle door handles usually use capacitive touch switches to automatically open the vehicle door. Specifically, the vehicle owner can touch the vehicle door equipped with a capacitive touch switch to change the mutual capacitance and voltage of the electrodes inside the capacitive touch switch, so as to wake up the body domain controller. After that, when the body domain controller detects the vehicle owner carrying the key, the vehicle door can be unlocked without the vehicle owner using the key for unlocking.

[0003] Currently, since the human body contains 70% water and its composition is similar to that of water, in rainy days, if rain hits the capacitive touch switch, it is also likely to have the same effect as human touch, causing the capacitive touch switch to be frequently mis-triggered.

[0040] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0041] It should be understood that when used in the specification and appended claims of the present application, the term "comprising" indicates the presence of the described features, wholes, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0042] In addition, in the description of the specification and the appended claims of the present application, the terms "first", "second", "third", etc. are only used for differential description and should not be construed as indicating or implying relative importance.

[0043] With the large-scale market launch of automated and intelligent vehicles, door handles usually adopt capacitive touch switches to automatically open the doors. Specifically, the vehicle owner can wake up the body domain controller by touching the door equipped with a capacitive touch switch. Then, when the body domain controller detects the vehicle owner carrying the key, the door can be unlocked without the vehicle owner using the key to unlock it.

[0044] Specifically, the capacitive touch switch detects whether someone touches it by detecting that when a person touches the touch switch, the capacitance value inside the touch switch can be changed. Refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of a door equipped with a capacitive touch switch provided by an embodiment of the present application; Figure 2 is a schematic structural diagram of a capacitive touch switch provided by an embodiment of the present application.

[0045] Among them, the capacitive touch switch internally includes two capacitors, one is a transmitting electrode and the other is a receiving electrode. Among them, the TX pin can provide a digital voltage and can also measure the charge received on the RX pin. The charge received on the RX electrode is proportional to the mutual capacitance between the two electrodes. When a finger is placed between the TX and RX electrodes, the mutual capacitance decreases, so the charge received on the RX electrode also decreases. Based on this, it is possible to determine whether the touch switch is in a touched state by detecting the charge on the RX electrode.

[0046] Currently, since the human body contains 70% water and its composition is similar to water, therefore, on rainy days, if rain hits the capacitive touch switch, it is also likely to have the same effect as human touch, causing the capacitive touch switch to be frequently mis-triggered, resulting in the capacitive touch switch continuously waking up the body domain controller to detect the door key. However, frequently waking up the body domain controller for detection easily causes the vehicle to lose power and wastes energy consumption.

[0047] Based on this, in order to avoid the situation where the capacitive touch switch frequently wakes up the body domain controller for detection due to being in a rainy environment, causing the vehicle to lose power, the embodiment of the present application provides a control method for a door, and this control method can be applied to a control device for the door. Among them, the control device can be a touch switch inside the door. Specifically, the above touch switch includes but is not limited to a capacitive touch switch and a resistive touch switch, and no limitation is made thereto. In the embodiment of the present application, the capacitive touch switch is taken as an example for explanation.

[0048] Please refer to Figure 3 , Figure 3 which shows the implementation flowchart of a method for controlling a vehicle door provided by an embodiment of the present application. The method includes the following steps:

[0049] S301. Obtain a first detection signal; the first detection signal is generated when a touch switch detects being touched.

[0050] In one embodiment, based on the above explanation of the capacitive touch switch, when not being touched, that is, when no finger is placed between the TX and RX electrodes, the mutual capacitance and voltage generally do not change. Based on this, when the touch switch detects a change in the mutual capacitance and voltage, it can be considered that the touch switch is touched, and thus the first detection signal can be generated.

[0051] S302. Obtain environmental information around the vehicle; the environmental information includes rainfall information.

[0052] In one embodiment, the above environmental information may further include information such as temperature, humidity, and wind speed. In the embodiments of the present application, since the touch switch may be mainly accidentally triggered by rain, when obtaining the environmental information, the rainfall information is mainly obtained.

[0053] In one embodiment, the above rainfall information may include the magnitude information of the rainfall, which can be divided into multiple levels. Exemplarily, the rainfall information can be divided into three level information: no rain, light rain, and heavy rain; or it can be divided into four level information: no rain, light rain, moderate rain, and heavy rain, which is not limited herein. For the sake of explanation, in the embodiments of the present application, the above rainfall information is described by taking the three level information of no rain, light rain, and heavy rain as an example.

[0054] Specifically, referring to Figure 4 , Figure 4 is a schematic diagram of an application scenario for a touch switch to obtain rainfall information in a method for controlling a vehicle door provided by an embodiment of the present application. The vehicle may be equipped with a rainfall sensor to monitor the current rainfall information in real time. Then, the rainfall sensor transmits the rainfall information to the vehicle controller, and then the controller transmits it to the touch switch through a communication bus.

[0055] Among them, the above controller includes but is not limited to a body domain controller, a vehicle controller, or a hybrid controller, which is not limited herein. In the embodiments of the present application, the control device is a body domain control device, which can interact with the capacitive touch switch. The communication bus includes but is not limited to multiple buses such as Controller Area Network (CAN) and Local Interconnect Network (LIN), which is not limited herein.

[0056] In another embodiment, the rain sensor can also directly transmit the rain information to the touch switch, and there is no limitation on this.

[0057] Among them, the vehicle dashboard can usually also display the local meteorological information. Therefore, the environmental information around the vehicle can also be determined according to the meteorological information. However, due to the possible delay of the meteorological information and the usually wide range of the meteorological information announced by the meteorological bureau, it may be inaccurate to determine the environmental information around the vehicle based on the meteorological information. Based on this, in this embodiment, sensor devices are usually used to obtain the environmental information in real time.

[0058] Exemplarily, the rain sensor can monitor the current rain information in real time, and the anemometer can monitor the current wind speed in real time to accurately obtain the above environmental information.

[0059] S303. According to the rain information and the target rule corresponding to the rain information; the target rule is used to determine whether the first detection signal is triggered by a person.

[0060] In one embodiment, the above target rule is a rule for determining whether the detection signal is triggered by a person. Among them, the touch switch can be pre-set with multiple rules, and each rule corresponds to a rain information. The touch switch can determine the target rule from multiple rules according to the currently detected rain information and the pre-set corresponding relationship between the rain information and the rules.

[0061] S304. If it is determined that the first detection signal meets the target rule, send a touch request to the controller; the controller is used to determine whether the touch request is valid and control the vehicle door based on the determination result.

[0062] In one embodiment, after receiving the touch request, the controller can determine whether the touch request is valid. Then, when the determination result is that the touch request is valid, the controller can drive the low-frequency antenna to detect the key to obtain the detection result. Then, the controller can perform a locking or unlocking operation on the vehicle door according to the detection result. Among them, controlling the vehicle door means performing operations such as locking or unlocking the vehicle door. Among them, when the determination result is that the touch request is invalid, the controller can ignore the touch request. That is, no control is performed on the vehicle door.

[0063] Exemplarily, the controller can obtain the control moment when the vehicle door was last controlled; then, when the second time difference between the control moment and the third acquisition moment when the touch request is obtained is greater than the second preset time difference, it is determined that the touch request is valid; and when the second time difference is less than or equal to the second preset time difference, it is determined that the touch request is invalid. Among them, the above second preset time difference can be set according to the actual situation, and there is no limitation on this.

[0064] Based on this, it can be considered that the controller will not respond to every touch request. Furthermore, the controller can also achieve the effect of non-essential response to touch requests, so as to further reduce the power consumption required by the vehicle.

[0065] Specifically, the detection result can be a successful result of detecting the key and a failure result of not detecting the key. Then, when the detection result is a successful result, perform a locking or unlocking operation on the vehicle door. For example, when the door lock state of the vehicle door is locked, an unlocking operation can be performed on the vehicle door; and when the door lock state of the vehicle door is unlocked, a locking operation can be performed on the vehicle door. In addition, when the detection result is a failure result, no operation can be performed on the vehicle door, that is, this touch request is ignored.

[0066] Among them, the first detection signal meeting the target rule can specifically be: the touch switch can determine the voltage value corresponding to the first detection signal; if the voltage value is less than the preset voltage threshold in the target rule, it is determined that the first detection signal meets the target rule. That is, it is determined that the first detection signal is triggered by someone. Then, the touch request is sent to the controller. If the voltage value is greater than or equal to the preset voltage threshold in the target rule, it is determined that the first detection signal does not meet the target rule, that is, it is determined that the first detection signal is triggered by rain or other objects. The touch switch can delete this first detection signal and does not need to send a touch request to the controller.

[0067] In addition, based on the above explanation of the capacitive touch switch, when the touch switch is touched, the voltage will change. However, different degrees of touch usually result in different voltage values. And different target rules usually correspond to different preset voltage thresholds. Based on this, in this embodiment, the first detection signal can be discriminated according to the preset voltage threshold corresponding to the target rule to determine whether the first detection signal is generated by the vehicle owner's touch.

[0068] Exemplarily, when the rain information is no rain, the preset voltage threshold in the corresponding target rule can be V1; when the rain information is light rain, the preset voltage threshold in the corresponding target rule can be V2; when the rain information is heavy rain, the preset voltage threshold in the corresponding target rule can be V3. Among them, V1 > V2 > V3, and the above preset voltage thresholds can all be calibrated in the corresponding environment in advance and stored in the touch switch of the vehicle door.

[0069] Specifically, when the touch switch is a capacitive touch switch, when a finger is placed between the TX and RX electrodes, the voltage received on the RX electrode will decrease. Therefore, when the touch switch is slightly touched, the voltage received on the RX is usually relatively high. Therefore, in a rainless environment, there will be no accidental touch of the touch switch by an object, or even if there is an accidental touch, the touch switch will not respond to this accidental touch because the composition is different from that of the human body. Based on this, this voltage value can be set to a relatively large voltage value so that when the vehicle owner touches the touch switch, a first detection signal can be quickly generated in response.

[0070] In a light rain environment, if the preset voltage threshold V1 corresponding to the rainless environment is still set, then when the rain beats on the touch switch, even if the penetration of the light rain is relatively low, the voltage value corresponding to the first detection signal generated is usually less than V1. Therefore, in order to avoid the influence of rain, in the embodiment of the present application, the preset voltage threshold V2 in the target rule corresponding to light rain can be set to be less than V1. That is, when the light rain beats on the touch switch, although the corresponding generated voltage value will be less than V1, it will be greater than V2. Therefore, the touch switch can determine that the first detection signal in this environment does not meet the target rule.

[0071] Similarly, in a heavy rain environment, if the preset voltage threshold V2 corresponding to the light rain environment is still set, then when the rain beats on the touch switch, due to the high penetration of the heavy rain, the voltage value corresponding to the first detection signal generated is usually less than V2. Therefore, also in order to avoid the influence of rain, in the embodiment of the present application, the preset voltage threshold V3 in the target rule corresponding to heavy rain needs to be less than V2. That is, when the heavy rain beats on the touch switch, although the corresponding generated voltage value will be less than V2, it will be greater than V3. Therefore, the touch switch can determine that the first detection signal in this environment does not meet the target rule.

[0072] Based on the above examples, in order to avoid the problem of mis-triggering, in light rain, in order to effectively filter the influence of environmental rain, only when the vehicle owner touches and further reduces the voltage value corresponding to the first detection signal until the voltage value is less than V2, will the touch switch determine that the first detection signal meets the target rule. Similarly, in heavy rain, in order to effectively filter the influence of heavy rain, only when the vehicle owner touches and further reduces the voltage value corresponding to the first detection signal until the voltage value is less than V3, will the touch switch determine that the first detection signal meets the target rule.

[0073] It should be noted that there is a preset voltage threshold corresponding to each rainfall information. That is, after determining the preset voltage threshold corresponding to the target rule, there is no need to compare the voltage value corresponding to the first detection signal with the preset voltage thresholds in other rules to avoid mis-triggering of the touch switch, thereby reducing the power consumption required by the vehicle.

[0074] It should be added that in the above embodiments, the preset voltage value in the target rule is only determined according to the rainfall information. However, the environmental information also includes information such as temperature, humidity, and wind speed. Among them, the magnitude of the wind speed may affect the penetration force when rain hits the touch switch. Therefore, in another embodiment, when determining the target preset rule, it can also be determined based on multiple environmental information.

[0075] Exemplarily, the preset voltage value in the target rule can also be determined comprehensively according to the rainfall information and the wind speed to improve the accuracy of discriminating the first detection signal. Specifically, the touch switch can be pre-set with multiple wind speed intervals. For example, a low wind speed interval, a medium wind speed interval, and a high wind speed interval, which can be set according to the actual situation and are not limited herein.

[0076] Based on this, after the anemometer obtains the wind speed, it can be matched with multiple pre-set wind speed intervals to determine the target wind speed interval. Then, the wind speed interval is sent to the controller, and then sent by the controller to the touch switch. Then, the touch switch can determine the target rule according to the current target wind speed interval and rainfall information, as well as the associated information between the pre-set wind speed interval, rainfall information, and preset rule.

[0077] Among them, the associated information between the pre-set wind speed interval, rainfall information, and preset rule can be shown in Table 1 below:

[0078] Table 1: Associated information between pre-set wind speed interval, rainfall information, and preset rule

[0079]

[0080]

[0081] Among them, V1, V2, and V3 in Table 1 above respectively represent preset voltage thresholds. It should be noted that when the detected rainfall information is no rain, even if the wind speed is high, it usually will not cause accidental touch of the touch switch. Therefore, the preset voltage threshold in the corresponding target rule can be the highest voltage threshold V1. However, when the detected rainfall information is light rain, with the addition of the wind speed, the penetration power of the rain will usually become higher. Therefore, the preset voltage threshold in the corresponding target rule will change with the magnitude of the wind speed. And when the rainfall information is heavy rain, the penetration power of the rain itself is relatively high. Therefore, the preset voltage threshold in the corresponding target rule can be the lowest voltage threshold V3.

[0082] It should be particularly noted that the above content is only an example of using a preset voltage threshold to compare with the voltage value corresponding to the first detection signal to determine whether the first detection signal meets the target rule when the touch switch is a capacitive touch switch. In another embodiment, when the touch switch is of other types, the target rule can also be changed correspondingly.

[0083] Exemplarily, since rain usually beats the touch switch intermittently, while the duration that the vehicle owner stays on the touch switch of the door handle is usually longer. Therefore, the target rule can also be a corresponding preset duration T. For example, it can be set that the preset duration T1 in the target rule corresponding to no rain is less than the preset duration T2 in the target rule corresponding to light rain, and less than the preset duration T3 in the target rule corresponding to heavy rain.

[0084] At this time, determining whether the first detection signal meets the target rule can be: if the detected duration of touch is greater than the preset duration in the target rule, it is determined that the first detection signal meets the target rule.

[0085] From the above example content, it can be seen that in the embodiments of the present application, not only can it be determined whether the first detection signal meets the target rule according to the preset voltage threshold, but also it can be determined whether the first detection signal meets the target rule according to other processing methods (preset duration). That is, in addition to the specific identification method recorded in the claims, those skilled in the art can also foresee that it can be achieved by other methods, which will not be elaborated herein.

[0086] In this embodiment, when the touch switch detects that it is touched, it can generate a first detection signal, and at the same time obtain the rainfall information around the vehicle, and determine a target rule corresponding to the rainfall information based on the rainfall information to discriminate the first detection signal obtained in this environment. Since the penetration power generated by the rainwater corresponding to different levels of rainfall information when hitting the touch switch is different, the touch switch can select an appropriate target rule according to the actual rainfall information to accurately discriminate the obtained detection signal to determine whether the first detection signal is triggered by a person. After that, when it is determined that the first detection signal meets the target rule, a touch request is sent to the controller to request the controller to determine whether the touch request is valid and control the vehicle door based on the determination result. Furthermore, it is possible to avoid the situation of frequently waking up the controller due to accidental touches of rainwater in a rainy environment, reduce the power consumption required by the vehicle, and in this environment, there is no need to put the touch switch or the controller in a sleep mode, which makes the vehicle owner unable to use the touch switch to open the vehicle door in a rainy environment and reduces the user experience. At the same time, the controller can also determine the validity of the touch request. When the sensitivity of unlocking and locking the vehicle door can be ensured, the effect of non-essential response of the controller to the touch request can be achieved at the same time. Furthermore, the power consumption required by the vehicle can be further reduced.

[0087] In another embodiment, when the touch switch has a fault or has stains on its surface, when the vehicle owner touches the touch switch, there is a situation of poor touch. As a result, the touch switch frequently sends touch requests to the controller in a short period of time to frequently wake up the controller for detection, which easily causes the vehicle to run out of power and wastes energy consumption.

[0088] Based on this, in order to reduce the power consumption required by the vehicle when the touch switch has a fault or poor touch, after it is determined that the first detection signal meets the target rule, the touch switch can also execute the S501-S504 steps as shown in Figure 5 shown below, the details are as follows:

[0089] S501. Determine the first acquisition time of the first detection signal.

[0090] S502. Determine the second acquisition time of the second detection signal that met the target rule last time.

[0091] In one embodiment, determining the first acquisition time of the first detection signal means that when the touch switch obtains the first detection signal when executing step S302, the touch switch can simultaneously determine the above-mentioned first acquisition time.

[0092] Similarly, the above-mentioned second acquisition time is also the time when the touch switch obtained the second detection signal last time. It should be noted that the second detection signal also needs to meet the target rule.

[0093] Specifically, after the touch switch executes the above S303 and S304 steps, at the next moment, when the touch switch can execute the above door control method again, when the above S303 step is executed again at this time, the first detection signal obtained this time is a new detection signal. Moreover, among the first detection signals obtained previously, the first detection signal relative to the new first detection signal at this time is the second detection signal, and the moment when the previously obtained first detection signal is obtained will correspond to the second acquisition moment.

[0094] It can be understood that in the description of the present application specification and the appended claims, the above "first", "second", etc. are only used for distinguishing descriptions, which are relative concepts and cannot be understood as indicating or implying relative importance.

[0095] S503. If it is determined that the first detection signal is valid according to the first acquisition moment and the second acquisition moment, send a touch request to the controller.

[0096] Specifically, the touch switch can first determine the first time difference between the first acquisition moment and the second acquisition moment. After that, when the first time difference is less than or equal to the first preset time difference, it is determined that the first detection signal is invalid; and when the first time difference is greater than the first preset time difference, it is determined that the first detection signal is valid.

[0097] Among them, the above first preset time difference can be set according to the actual situation. In this embodiment, since the process for the controller to control the door to complete locking or unlocking usually takes 600 ms from receiving the touch request. Therefore, the above first preset time can be 600 ms.

[0098] It should be added that if the touch switch frequently sends touch requests to the controller due to poor contact of the vehicle owner within 600 ms, the controller will control the door to perform repetitive operations such as unlocking and locking multiple times, resulting in unnecessary unlocking and locking situations.

[0099] Based on this, when the first time difference is greater than the above 600 ms, it can be considered that the first detection signal is valid. At the same time, when it is determined in the above S304 step that the first detection signal meets the target rule, the touch switch can send a touch request to the controller to control the door.

[0100] S504. If it is determined that the first detection signal is invalid according to the first acquisition moment and the second acquisition moment, stop sending touch requests to the controller.

[0101] In one embodiment, when it is determined that the first detection signal is invalid, it can be considered that although the first detection signal generated at this time is generated when the vehicle owner touches, the touch frequency is too frequent. Therefore, in order to avoid problems such as unnecessary unlocking and locking caused by poor touch of the vehicle owner, the touch switch can ignore this first detection signal. That is, there is no need to send a touch request to the controller.

[0102] Specifically, referring to Figure 6 、 Figure 7 and Figure 8 , Figure 6 、 Figure 7 and Figure 8 are all schematic diagrams of application scenarios for determining the first detection signal in a method for controlling a vehicle door provided in an embodiment of the present application. In Figure 6 , if the second touch is generated at the current moment and the first detection signal corresponding to the second touch meets the target rule, then the current moment is the first acquisition moment. Similarly, when the detection signal corresponding to the first touch meets the target rule, the detection signal corresponding to the first touch is the second detection signal, and the moment corresponding to the first touch is the second acquisition moment. At this time, the first time difference between the first acquisition moment and the second acquisition moment is greater than 600 ms. That is, the interval duration between two touches of the vehicle owner is greater than 600 ms. Therefore, it can be considered that the second touch is valid.

[0103] Similarly, in Figure 7 , if the second touch is generated at the current moment and the first detection signal corresponding to the second touch meets the target rule, then the current moment is the first acquisition moment. At this time, the first time difference between it and the second detection signal corresponding to the first touch is less than 600 ms. Therefore, it can be considered that the second touch is invalid. Then, at the third touch, at this time, it can be considered that the detection signal corresponding to the third touch is the first detection signal, and the corresponding moment is the first acquisition moment. Then, because the detection signal corresponding to the second touch meets the target rule, therefore, relative to the first detection signal corresponding to the third touch, the detection signal corresponding to the second touch can be considered as the second detection signal, and the corresponding moment will change to the second acquisition moment. Furthermore, from Figure 7 it can be seen that the first time difference between the second touch and the third touch is greater than 600 ms. Therefore, it can be considered that the first detection signal corresponding to the third touch is valid.

[0104] Similarly, in Figure 8Among them, the first time difference between the detection signal corresponding to the fourth touch and the detection signal corresponding to the third touch is greater than 600 ms. Therefore, it can be considered that the third touch is valid. However, the first time difference between the detection signal corresponding to the third touch and the detection signal corresponding to the second touch is less than 600 ms, and the first time difference between the detection signal corresponding to the second touch and the detection signal corresponding to the first touch is less than 600 ms. Therefore, it can be considered that the second touch and the third touch are invalid.

[0105] Based on the above explanation of Figure 6 , Figure 7 and Figure 8 , it can be seen that although the detection signals corresponding to each touch all meet the target rule, when determining whether the detection signal is valid, the first time difference between the first detection signal at the current moment and the second detection signal that meets the target rule at the adjacent previous moment is compared with the first preset time difference. Taking Figure 8 as an example, if the detection signal corresponding to the second touch does not meet the target rule, then the first time difference between the detection signal corresponding to the third touch and the detection signal corresponding to the first touch will be compared with the first preset time difference.

[0106] Referring to Figure 9 , a schematic flow chart of another method for controlling a vehicle door provided by an embodiment of the present application is shown, which may specifically include the following steps:

[0107] S901. Obtain a touch request; the touch request is sent by the touch switch to the controller when it detects that the first detection signal meets the target rule; the first detection signal is generated by the touch switch when it detects being touched; the target rule is a target rule corresponding to the rainfall information around the vehicle.

[0108] In the embodiment of the present application, the execution subject of the above method for controlling a vehicle door is the controller. Among them, the controller, the touch request, the first detection signal, the target rule, and the rainfall information have been explained above, and will not be described again here.

[0109] S902. Determine whether the touch request is valid, and control the vehicle door based on the determination result.

[0110] In one embodiment, determining whether the touch request is valid may be: the controller may first determine the control moment when the vehicle door was last controlled, and determine the third acquisition moment when the touch request is obtained. Then, determine whether the touch request is valid according to the control moment and the third acquisition moment.

[0111] Specifically, the controller can pre-determine a second time difference between the control moment and the third acquisition moment when the touch request is acquired; thereafter, when the second time difference is greater than the second preset time difference, it is determined that the touch request is valid. And when the second time difference is less than or equal to the second preset time difference, it is determined that the touch request is invalid.

[0112] Among them, the control moment of the last control of the vehicle door is the moment when the controller last received a touch request and drove the low-frequency antenna to perform the key detection function to control the vehicle door according to the detection result. The above second preset time difference can be set according to the actual situation, and no limitation is made thereto.

[0113] It should be noted that when the touch request is determined to be valid, the controller can respond to the touch request to control the vehicle door; when the touch request is invalid, the controller can ignore the touch request. That is, keep the state of the vehicle door unchanged.

[0114] Among them, controlling the vehicle door means performing operations such as unlocking or locking the vehicle door.

[0115] It should be added that the above-mentioned process of the controller from receiving the touch request to completing the locking or unlocking of the vehicle door usually takes 600 ms. And when the touch switch is in poor contact, touch requests will be frequently sent to the controller in a short period of time. That is, there is an operation of unlocking or locking immediately when the vehicle door has just been locked or unlocked. Based on this, in order to avoid unnecessary unlocking and locking caused by poor contact, in this embodiment, the above second preset time difference can be set to be greater than the first preset time difference. Exemplarily, the second preset time difference t can be 1S.

[0116] Specifically, referring to Figure 10 , Figure 10 is a schematic diagram of an application scenario for determining a touch request in a method for controlling a vehicle door provided in an embodiment of the present application. Taking the vehicle door being locked as an example, if it is necessary to control the vehicle door to unlock, the second time difference between the third acquisition moment of the touch request received again and the control moment when the vehicle door is locked needs to be greater than the second preset time difference. Therefore, when the second time differences between the touch requests corresponding to the second touch and the third touch and the control moment of completing the locking are both less than the second preset time difference t, the controller can ignore the touch requests corresponding to the second touch and the third touch and only respond to the touch request corresponding to the fourth touch.

[0117] In this embodiment, since the touch request is sent by the touch switch to the controller after detecting that the first detection signal meets the target rule corresponding to the rainfall information, it can be considered that the touch request is generated after the touch switch is touched by a person, reducing the number of times of frequently sending touch requests to the controller due to accidental touch by rain, and further reducing the power consumption required by the vehicle when frequently waking up the controller. After that, when the controller obtains the touch request, it can determine the control moment when the door was last unlocked or locked. Then, the controller can determine whether the current touch request is valid according to the control moment, and when it is valid, control the door again according to the touch request. Otherwise, when it is invalid, the current touch request is ignored. In this way, the controller does not need to frequently respond to the touch requests sent by the touch switch each time, further reducing the power consumption required by the vehicle.

[0118] It should be specifically noted that, in order to reduce the power consumption required by the vehicle in the case where the touch switch frequently wakes up the controller for detection within a short period of time, in the embodiments of the present application Figure 3 and Figure 5 the corresponding method embodiments can be applied to the touch switch. At the same time, in order to further reduce the power consumption required by the vehicle in the case where the controller frequently responds to touch requests within a short period of time, in the embodiments of the present application Figure 9 the corresponding method embodiments can be applied to the controller. In this way, when the door control method provided in the embodiments of the present application is simultaneously applied to the touch switch and the controller, while ensuring the sensitivity of door unlocking and locking, it can also simultaneously achieve the situation of unnecessary wake-up of the touch switch and unnecessary response of the controller. Furthermore, the power consumption required by the vehicle can be further reduced.
