Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile electronics, and in particular to a touch sensing door opening method and device for a vehicle and a storage medium. BACKGROUND

[0002] Nowadays, in order to improve the user experience, the door handle of the vehicle needs to be installed with an inductive capacitive sensor. When the user approaches the vehicle, as long as the vehicle senses that the remote key of the vehicle is nearby, the user can achieve vehicle door unlocking by touching the door handle, that is, the user can open the vehicle door in a touch sensing manner, thereby realizing the diversification of the vehicle door opening method.

[0003] However, the inductive capacitive sensor cannot distinguish the attributes of the object, so in some scenarios, the vehicle door may be opened due to the accidental touch of the door handle by the object. For example, when the user is driving the vehicle in heavy rain, if the rain touches the door handle, the inductive capacitive sensor may trigger an electrical release request, causing the body domain controller to control the vehicle door to be unlocked, which may affect the user's safety.

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0052] Before the touch sensing door opening method of a vehicle provided by an embodiment of the present application is explained in detail, the application scenarios and implementation environments involved in the embodiment of the present application are introduced.

[0053] In the development of the automotive industry today, improving the overall driving experience of users is given a high priority, which has prompted the diversification of innovations in door unlocking mechanisms. The way of opening the door by mechanical key has been gradually replaced by more convenient and intelligent unlocking methods. Users can unlock the door through fingerprint recognition, facial recognition, or even through a smartphone application. This greatly improves the convenience of user interaction with the vehicle and brings users a comfortable driving experience.

[0054] In related technologies, some vehicles are equipped with inductive capacitive sensors on the door handle. When an object approaches one of the metal plates of the capacitive sensor, it will cause a change in the capacitance value. This change can be detected by a measurement circuit and converted into an electrical signal output. Therefore, when a user approaches a vehicle, as long as the vehicle senses that the vehicle's remote key is nearby, the user can unlock the door by touching the door handle, that is, the user can open the door through touch induction. However, inductive capacitive sensors cannot distinguish the properties of objects, so in some scenarios, the door may be opened due to the door handle being accidentally touched by an object. For example, when a user is driving in heavy rain, the inductive capacitive sensor may trigger an electrical release request when rain touches the door handle, causing the vehicle body domain controller to control the door to unlock, which can affect the user's safety.

[0055] Therefore, based on this, the embodiments of the present application provide a touch induction door opening method for a vehicle. By comprehensively analyzing the motion state of the vehicle, whether the vehicle is in a car washing mode, the rainfall level of the external environment of the vehicle, and other information, in the case that the inductive capacitive sensor is not faulty, the vehicle is not in a motion state, the vehicle is not in a car washing mode, the rainfall level of the external environment of the vehicle indicates that the rainfall is small, the inductive capacitive sensor triggers an electrical release request, and the remote key of the vehicle is located within a first distance range of the vehicle, the operation of controlling the door to unlock is performed. In the case that the vehicle is in a motion state, or the vehicle is in a car washing mode, or the rainfall level of the external environment of the vehicle indicates that the rainfall is large, even if the inductive capacitive sensor triggers an electrical release request, the operation of controlling the door to unlock is not performed. That is, the embodiments of the present application determine whether to control the door to unlock by combining comprehensive judgments from multiple aspects, which can avoid dangerous situations where the door is opened during the motion of the vehicle, and can also avoid situations where the door is accidentally opened due to rain touching the door handle when the user has no need to open the door, thereby ensuring the safety of the user and improving the user's driving experience.

[0056] For reference Figure 1 , Figure 1Fig. 1 is a schematic diagram of an implementation environment according to an exemplary embodiment. The implementation environment includes a body domain controller 101, an inductive capacitive sensor 102, a rain sensor 103, a wireless communication receiver 104, a door lock motor 105, and a door 106. The body domain controller 101 can be connected with the inductive capacitive sensor 102 through a wire to directly transmit an electrical signal. The body domain controller 101 can be connected with the rain sensor 103, the wireless communication receiver 104, and the door lock motor 105 through a CAN (Controller Area Network) bus or a LIN (Local Interconnect Network) bus to transmit data.

[0057] If the inductive capacitive sensor 102 is not faulty, the vehicle is not in a motion state, and the vehicle is not in a car washing mode, the body domain controller 101 sends a wake-up instruction to the rain sensor 103 to make the rain sensor 103 start detecting the rain of the external environment of the vehicle. After receiving the wake-up signal sent by the body domain controller 101, the rain sensor 103 detects the rain of the external environment of the vehicle and sends rain data to the body domain controller 101.

[0058] After receiving the rain data sent by the rain sensor 103, the body domain controller 101 determines the rain level of the external environment of the vehicle based on the rain data. If it is determined that the rain level of the external environment of the vehicle is less than or equal to a first rain level and the inductive capacitive sensor 102 triggers an electrical release request, the body domain controller 101 determines whether the remote key of the vehicle is located within a first distance range of the vehicle according to whether the wireless communication receiver 104 sends a detection success signal. If it is determined that the remote key of the vehicle is located within the first distance range of the vehicle, the body domain controller 101 controls the corresponding door 106 of the inductive capacitive sensor 102 to be unlocked by sending an unlock signal to the door lock motor 105.

[0059] It should be noted that the wireless communication receiver 104 detects whether the remote key of the vehicle is located within the first distance range of the vehicle by receiving a wireless signal sent by the remote key of the vehicle, and sends a detection success signal to the body domain controller 101 when it is detected that the remote key of the vehicle is located within the first distance range of the vehicle.

[0060] The rain sensor 103 can be any sensor that can detect the size of the rain, such as an optical rain sensor, a radar rain sensor, an infrared rain sensor, etc.

[0061] The wireless communication receiver 104 can be any receiver that can receive a wireless signal sent by a remote key, such as a Bluetooth receiver, an ultra-wideband receiver, a near-field communication receiver, etc.

[0062] Those skilled in the art shall understand that the rain sensor 103 and the wireless communication receiver 104 described above are only examples, and other existing or future rain sensors and wireless communication receivers that can be applicable to the embodiments of the present application shall also be included in the protection scope of the embodiments of the present application, and are hereby included by reference.

[0063] It shall be noted that the application scenarios and implementation environments described in the embodiments of the present application are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the appearance of new application scenarios and the evolution of implementation environments, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0064] Next, the method for opening the door of the vehicle by touch sensing provided by the embodiments of the present application is explained in detail.

[0065] Figure 2 is a flowchart of the method for opening the door of the vehicle by touch sensing provided by the embodiments of the present application. The door handle of the vehicle is provided with an inductive capacitive sensor, and the method is applied to the body domain controller. Please refer to Figure 2 The method includes the following steps.

[0066] Step 201: If the inductive capacitive sensor is not faulty, the vehicle is not in a motion state, and the vehicle is not in a car washing mode, determine the rain level of the external environment of the vehicle.

[0067] That is, before determining the rain level of the external environment of the vehicle, it is necessary to first determine whether the inductive capacitive sensor is faulty, whether the vehicle is in a motion state, and whether the vehicle is in a car washing mode.

[0068] Next, the method for determining whether the inductive capacitive sensor is faulty is introduced.

[0069] In some embodiments, the body domain controller detects whether the output signal of the inductive capacitive sensor has abnormal fluctuations. If it is detected that the output signal of the inductive capacitive sensor has no abnormal fluctuations, it is determined that the inductive capacitive sensor is not faulty. If it is detected that the output signal of the inductive capacitive sensor has abnormal fluctuations, it is determined that the inductive capacitive sensor is faulty.

[0070] When an object approaches or touches the inductive capacitive sensor, the inductive capacitive sensor is triggered, converts the sensed approach / touch event into an electrical signal with certain characteristics, and sends the electrical signal to the body domain controller. That is, the inductive capacitive sensor triggers the electrical release request by sending the electrical signal with certain characteristics to the body domain controller. For example, when the approach / touch event is sensed, the inductive capacitive sensor sends a PWM (Pulse Width Modulation) signal with certain frequency and duty cycle to the body domain controller, thereby triggering the electrical release request. When there is no object approaching / touching the inductive capacitive sensor, the voltage output by the inductive capacitive sensor is the voltage value of the entire vehicle, which is usually 12V, 24V, etc.

[0071] For example, if the body domain controller detects that the output signal of the inductive capacitive sensor has noise, high-frequency oscillation near the rising edge or falling edge of the output signal, or waveform distortion of the output signal, it is determined that the output signal of the inductive capacitive sensor has abnormal fluctuations.

[0072] Alternatively, the body domain controller can periodically detect whether the output signal of the inductive capacitive sensor has abnormal fluctuations after the entire vehicle is powered on. The embodiments of the present application do not limit the size of the detection period.

[0073] In addition, other methods can be used to determine whether the inductive capacitive sensor is malfunctioning, and the embodiments of the present application do not limit this.

[0074] The method for determining whether the vehicle is in a moving state is described below:

[0075] In some embodiments, the vehicle is provided with a wheel speed sensor. In this case, the method for determining whether the vehicle is in a moving state can be as follows: the body domain controller acquires the wheel speed sent by the wheel speed sensor; when the wheel speed is zero, it is determined that the vehicle is not in a moving state, and when the wheel speed is not zero, it is determined that the vehicle is in a moving state.

[0076] In some embodiments, the ECU (Engine Control Unit) of the vehicle controls the speed of the engine and the opening degree of the throttle. In this case, the method for determining whether the vehicle is in a moving state can be as follows: the ECU sends the speed of the engine and the opening degree of the throttle to the body domain controller, and the body domain controller determines whether the speed of the engine is zero and whether the opening degree of the throttle is greater than an intake threshold based on the speed of the engine and the opening degree of the throttle sent by the ECU; if the speed of the engine is not zero and the opening degree of the throttle is greater than the intake threshold, it is determined that the vehicle is in a moving state, otherwise, it is determined that the vehicle is not in a moving state.

[0077] The throttle opening degree refers to the degree to which a throttle valve plate in an engine intake system is opened. The greater the throttle opening degree, the greater the air flow into the engine, and the greater the output power of the engine. When the throttle opening degree is greater than an intake threshold, the output power of the engine can drive the wheels to rotate.

[0078] In addition, whether the vehicle is in motion can also be determined by other methods, which are not limited in the embodiments of the present application.

[0079] The method for determining whether the vehicle is in the car washing mode is described below.

[0080] In some embodiments, the vehicle is equipped with a dedicated car washing mode button, and the user can press the button to activate the car washing mode when needed. The body domain controller monitors the state of the car washing mode button. If the body domain controller detects that the car washing mode button is pressed, it is determined that the vehicle is in the car washing mode. Otherwise, it is determined that the vehicle is not in the car washing mode.

[0081] In addition, whether the vehicle is in the car washing mode can also be determined by other methods, which are not limited in the embodiments of the present application.

[0082] In some embodiments, if the inductive capacitive sensor is faulty, or the vehicle is in motion, or the vehicle is in the car washing mode, and the inductive capacitive sensor triggers an electric release request, the electric release request triggered by the inductive capacitive sensor is shielded.

[0083] It should be noted that shielding the electric release request triggered by the inductive capacitive sensor means not performing the step of controlling the unlocking of the door corresponding to the inductive capacitive sensor.

[0084] When the inductive capacitive sensor is faulty, the inductive capacitive sensor may trigger an electric release request without being approached / touched by an object. If the vehicle is in motion and the door is unlocked, there will be a great risk of driving safety. When the vehicle is in the car washing mode, if the door is unlocked, the high-pressure water gun or other cleaning equipment may splash water into the vehicle, causing the seats, carpets and other interior components to be wet, and even causing electronic devices to be damaged. Therefore, in these scenarios, shielding the electric release request triggered by the inductive capacitive sensor can avoid the inductive capacitive sensor from mistakenly triggering an electric release request and causing the door to open when the user does not intend to open the door, can avoid the door from being opened during the motion of the vehicle, and can avoid the interior components of the vehicle from being wet or the electronic devices from being damaged during car washing, thereby ensuring the safety of the user and improving the user's experience of using the vehicle.

[0085] If it is determined that the inductive capacitive sensor is not faulty, the vehicle is not in a state of motion, and the vehicle is not in a car washing mode, the rain level of the external environment of the vehicle can be determined next, and then it is determined whether to shield the electrical release request triggered by the inductive capacitive sensor according to the rain level of the external environment of the vehicle or according to the rain level of the external environment of the vehicle and other information.

[0086] In some embodiments, the vehicle is provided with a rain sensor; if the inductive capacitive sensor is not faulty, the vehicle is not in a state of motion, and the vehicle is not in a car washing mode, the body domain controller sends a wake-up instruction to the rain sensor to make the rain sensor start detecting the rain of the external environment of the vehicle; after receiving the wake-up instruction, the rain sensor detects the rain of the external environment of the vehicle and sends the rain data to the body domain controller; after receiving the rain data sent by the rain sensor, the body domain controller determines the rain level of the external environment of the vehicle based on the rain data sent by the rain sensor.

[0087] The rain sensor can be any sensor that can detect the amount of rain, such as an optical rain sensor, a radar rain sensor, an infrared rain sensor, etc.

[0088] The rain level generally includes heavy rain level, medium rain level, light rain level, and no rain level.

[0089] In some embodiments, determining the rain level of the external environment of the vehicle based on the rain data sent by the rain sensor includes: the body domain controller compares the rain data with a first rain threshold value; if it is determined that the rain data is less than the first rain threshold value, it is determined that the rain level of the external environment of the vehicle is no rain level; if it is determined that the rain data is equal to the first rain threshold value, it is determined that the rain level of the external environment of the vehicle is light rain level; and if it is determined that the rain data is greater than the first rain threshold value, it is determined that the rain level of the external environment of the vehicle is medium rain level or heavy rain level.

[0090] The first rain threshold value is set in advance, and the specific size of the first rain threshold value is not limited in the embodiments of the application.

[0091] Optionally, after receiving the wake-up instruction, the rain sensor first judges whether its state is normal before detecting the rain of the external environment of the vehicle, so as to send a corresponding verification signal to the body domain controller; if it is determined that the state is abnormal, a first verification signal is sent to the body domain controller; if it is determined that the state is normal, a second verification signal is sent to the body domain controller; after receiving the verification signal sent by the rain sensor, the body domain controller determines the rain level of the external environment of the vehicle based on the rain data sent by the rain sensor if it is determined that the verification signal is the first verification signal, otherwise, the step is not executed.

[0092] In this way, the validity of the rainfall data sent by the rainfall sensor can be determined, so as to ensure that the body domain controller can accurately determine the rainfall level of the external environment of the vehicle.

[0093] In some embodiments, after receiving the wake-up instruction, the rainfall sensor detects the rainfall of the external environment of the vehicle, determines the rainfall level corresponding to the detected rainfall, and then sends a rainfall level signal to the body domain controller, the rainfall level signal indicating the rainfall level of the external environment of the vehicle. In this case, the body domain controller can directly determine the rainfall level of the external environment of the vehicle based on the received rainfall level signal.

[0094] For example, it is assumed that at the code level, the rainfall sensor and the body domain controller use RSM_Rainfall to represent “rainfall level”, use the value 0x0 to represent “no rain level”, use the value 0x1 to represent “light rain level”, use the value 0x2 to represent “moderate rain level”, and use the value 0x3 to represent “heavy rain level”. Then, when the rainfall sensor determines that the rainfall level corresponding to the detected rainfall is moderate rain level, RSM_Rainfall = 0x2. The rainfall sensor sends “0x2” as the rainfall level signal to the body domain controller. After receiving “0x2” sent by the rainfall sensor, the body domain controller can determine that the rainfall level of the external environment of the vehicle is moderate rain level.

[0095] Step 202: If the rainfall level of the external environment of the vehicle is less than or equal to the first rainfall level, and the inductive capacitive sensor triggers an electric release request, it is determined whether the remote key of the vehicle is located within the first distance range of the vehicle.

[0096] In some embodiments, the first rainfall level is light rain level. That is, when the rainfall level of the external environment of the vehicle is less than or equal to the first rainfall level, it can be considered that the external environment of the vehicle is less than or no rain, and when the rainfall level of the external environment of the vehicle is greater than the first rainfall level, it can be considered that the external environment of the vehicle is moderate rain or heavy rain.

[0097] When the external environment of the vehicle is less than or no rain, even if rain falls on the door handle, the inductive capacitive sensor is difficult to be triggered, and the inductive capacitive sensor is almost not triggered to release the electric request. Therefore, in this case, if the inductive capacitive sensor triggers an electric release request, it is very likely that the user's approach / touch triggers the inductive capacitive sensor, so it can be determined next whether the remote key of the vehicle is located within the first distance range of the vehicle to determine whether to control the door unlocking.

[0098] It is mentioned above that the inductive capacitive sensor triggers an electric release request by sending an electric signal with certain characteristics to the body domain controller.

[0099] In some embodiments, the inductive capacitive sensor outputs a PWM signal of a first frequency and a first duty cycle when triggered, and the maximum voltage amplitude of the PWM signal is a first level and the minimum voltage amplitude is a second level; the inductive capacitive sensor outputs a signal of the first level when not triggered; the process in which the body domain controller determines whether the inductive capacitive sensor is triggered by the electric discharge request can include steps (1)-(3) as follows:

[0100] (1) detecting the signal output by the inductive capacitive sensor to determine whether there is a voltage value less than the first level in the signal output by the inductive capacitive sensor.

[0101] The first level is the voltage value of the whole vehicle, which is usually 12V or 24V, and the second level is less than the voltage value of the whole vehicle.

[0102] Since the inductive capacitive sensor outputs a signal of the first level when not triggered and outputs a PWM signal of the first frequency and the first duty cycle when triggered, the voltage amplitude of the PWM signal is less than or equal to the first level, so when there is a voltage value less than the first level in the signal output by the inductive capacitive sensor, it indicates that the inductive capacitive sensor may be triggered.

[0103] Optionally, the body domain controller collects the signal output by the inductive capacitive sensor at a third frequency and performs detection. The third frequency is set in advance and the third frequency is large, which can be 10kHz or 15kHz, and the specific size of the third frequency is not limited in the embodiments of the present application. In this way, the body domain controller collects the signal output by the inductive capacitive sensor at a large frequency, which can avoid missing detection, i.e., avoid the situation that the voltage value less than the first level in the signal output by the inductive capacitive sensor is not detected.

[0104] (2) If there is a voltage value less than the first level in the signal output by the inductive capacitive sensor, the signal continuously output by the inductive capacitive sensor within a first time duration is obtained as a sample signal. Otherwise, step (1) is continued.

[0105] When there is a voltage value less than the first level in the signal output by the inductive capacitive sensor, it indicates that the inductive capacitive sensor may be triggered. At this time, the signal continuously output by the inductive capacitive sensor within a first time duration can be further obtained as a sample signal, and the sample signal is detected to determine whether the sample signal is consistent with the signal output by the inductive capacitive sensor when triggered, i.e., whether it is a PWM signal of the first frequency, the first duty cycle, and the maximum voltage amplitude is the first level and the minimum voltage amplitude is the second level.

[0106] It should be noted that the first time length is usually greater than the reciprocal of the first frequency. In this way, the PWM signal output when the inductive capacitive sensor is triggered at least once can be obtained, facilitating subsequent analysis.

[0107] (3) If the sample signal is a PWM signal with the first frequency, the first duty cycle, and the maximum voltage amplitude being the first level and the minimum voltage amplitude being the second level, it is determined that the inductive capacitive sensor triggers the electric release request. Otherwise, it is determined that the inductive capacitive sensor does not trigger the electric release request.

[0108] It should be noted that the specific size of the first frequency and the first duty cycle is determined by the inductive capacitive sensor itself, and the embodiments of the present application do not limit this.

[0109] Optionally, if the sample signal is a PWM signal with the frequency within the second frequency range, the duty cycle within the second duty cycle range, the maximum voltage amplitude being the first level and the minimum voltage amplitude being the second level, it is determined that the inductive capacitive sensor triggers the electric release request.

[0110] The second frequency range is centered on the first frequency, and the second duty cycle range is centered on the first duty cycle. The embodiments of the present application do not limit the specific size of the second frequency range and the second duty cycle range. In general, the difference between the maximum frequency and the minimum frequency of the second frequency range is small, and the difference between the maximum duty cycle and the minimum duty cycle of the second duty cycle range is also small. For example, the first frequency is 500 Hz, the second frequency range is 450 Hz-550 Hz, the first duty cycle is 25%, and the second duty cycle range is 20%-30%.

[0111] Since the inductive capacitive sensor is inevitably subject to various disturbances (including external disturbances and internal circuit clutter disturbances), by appropriately expanding the detection range of the frequency and the duty cycle of the sample signal, the de-bouncing function can be realized, and the situation that the inductive sensor is mistakenly considered not to trigger the electric release request due to the too small detection range can be largely avoided.

[0112] In actual application, the de-bouncing function can also be realized by adding appropriate filter circuits at the sending end of the internal circuit of the inductive capacitive sensor and the receiving end of the internal circuit of the vehicle body domain controller.

[0113] In some embodiments, if the rainfall level of the external environment of the vehicle is greater than the first rainfall level, and the inductive capacitive sensor triggers the electric release request, the electric release request triggered by the inductive capacitive sensor is shielded.

[0114] When the rain level of the external environment of the vehicle is greater than the first rain level, it indicates that the external environment of the vehicle is moderate rain or heavy rain. At this time, if rain falls on the door handle, the inductive capacitive sensor is likely to be triggered. Therefore, when the rain level of the external environment of the vehicle is greater than the first rain level, if the inductive capacitive sensor triggers an electric release request, the electric release request triggered by the inductive capacitive sensor is shielded, so that the situation that the vehicle door is accidentally unlocked due to the inductive capacitive sensor triggered by rain is avoided.

[0115] The method for determining whether the remote key of the vehicle is located within the first distance range of the vehicle is described as follows:

[0116] In some embodiments, the vehicle is provided with a wireless communication receiver, and the remote key of the vehicle and the wireless communication receiver have mutually matched communication modules; the wireless communication sensor detects whether the remote key of the vehicle is located within the first distance range of the vehicle by receiving the wireless signal sent by the remote key of the vehicle, and sends a detection success signal to the body domain controller when it is detected that the remote key of the vehicle is located within the first distance range of the vehicle; the body domain controller determines that the remote key of the vehicle is located within the first distance range of the vehicle after receiving the detection success signal sent by the wireless communication sensor.

[0117] The wireless communication receiver can be any receiver that can receive the wireless signal sent by the remote key of the vehicle, such as a Bluetooth receiver, an ultra-wideband receiver, a near-field communication receiver, etc.

[0118] The first distance range is set in advance, and the specific size of the first distance range is not limited in the embodiments of the application.

[0119] In addition, other methods can also be used to determine whether the remote key of the vehicle is located within the first distance range of the vehicle, which is not limited in the embodiments of the application.

[0120] It should be noted that the above is described by taking the first rain level as the light rain level as an example. In fact, the first rain level can be set as any one of the heavy rain level, the moderate rain level, the light rain level or the no rain level according to the sensitivity of the inductive capacitive sensor. Generally, when the sensitivity of the inductive capacitive sensor is high, the first rain level can be set as the no rain level or the light rain level, and when the sensitivity of the inductive capacitive sensor is low, the first rain level can be set as the moderate rain level or even the heavy rain level.

[0121] Step 203: If the remote key of the vehicle is located within the first distance range of the vehicle, the inductive capacitive sensor corresponding to the vehicle door is controlled to be unlocked.

[0122] If the remote key of the vehicle is not located within the first distance range of the vehicle, the inductive capacitive sensor corresponding door is not controlled to be unlocked.

[0123] If the remote key of the vehicle is located within the first distance range of the vehicle, it means that the user is indeed near the vehicle. Therefore, if someone triggers the inductive capacitive sensor by approaching / touching the door handle, it can be considered that the user himself triggers it, rather than others. That is, by determining whether the remote key of the vehicle is located within the first distance of the vehicle to determine whether the door is indeed controlled to be unlocked, the safety of the user using the vehicle can be further ensured.

[0124] In some embodiments, if the remote key of the vehicle is located within the first distance range of the vehicle, the body domain controller controls the inductive capacitive sensor corresponding door to be unlocked by sending an unlock signal to the door lock motor.

[0125] That is, after the body domain controller sends an unlock signal to the door lock motor, the door lock motor receives the unlock signal sent by the body domain controller, and controls the inductive capacitive sensor corresponding door to be unlocked based on the unlock signal.

[0126] In some embodiments, before controlling the inductive capacitive sensor corresponding door to be unlocked, the method further comprises: determining whether the window on the inductive capacitive sensor corresponding door is at a target position, the target position being higher than the completely closed position of the window; if the window is at the target position, controlling the window to be lowered so that the window does not scratch the roof seal strip during the opening of the door, otherwise, performing the step of controlling the inductive capacitive sensor corresponding door to be unlocked.

[0127] There are many implementation manners for the above process. For example, the vehicle is provided with a window motor, and the window motor is provided with a position sensor such as a Hall effect sensor or a rotary transformer for monitoring the position of the window in real time. The body domain controller can determine whether the window on the inductive capacitive sensor corresponding door is at a target position by reading the data sent by the position sensor. If the window is at the target position, the body domain controller controls the window to be lowered by controlling the window motor, so that the window does not scratch the roof seal strip during the opening of the door, otherwise, the body domain controller controls the inductive capacitive sensor corresponding door to be unlocked by controlling the door lock motor.

[0128] This case is mainly for frameless windows. For frameless windows, after the window is completely closed, it can often be raised again to embed the upper edge of the window into the roof seal strip, thereby achieving complete sealing of the vehicle. Therefore, by controlling the window to be lowered when the window is at the target position, the window can be protected from scratching the roof seal strip during the opening of the door.

[0129] Optionally, if the vehicle window is in the target position, the vehicle window is controlled to be lowered to a first opening position, and then the step of controlling the vehicle door corresponding to the inductive capacitive sensor to be unlocked is performed. The first opening position is a position lower than the fully closed position of the vehicle window and a position that can ensure that rainwater outside the vehicle will not penetrate into the vehicle.

[0130] In this way, if the vehicle door is opened when the external environment of the vehicle is light rain, the vehicle interior or electronic equipment can be protected from being wetted by rainwater while the vehicle window is protected.

[0131] In some embodiments, before the vehicle door corresponding to the inductive capacitive sensor is controlled to be unlocked, the method further includes: if there is an object within a second distance range outside the vehicle, performing the step of controlling the vehicle door corresponding to the inductive capacitive sensor to be unlocked; and if there is no object within the second distance range outside the vehicle, shielding the electrical release request triggered by the inductive capacitive sensor.

[0132] The second distance range is set in advance, and the specific size of the second distance range is not limited in the embodiments of the application.

[0133] Before the vehicle door corresponding to the inductive capacitive sensor is controlled to be unlocked, whether the inductive capacitive sensor is triggered by the user's approach / touch can be further confirmed by judging whether there is an object within the second distance range outside the vehicle. If there is an object within the second distance range outside the vehicle, it further indicates that the inductive capacitive sensor is triggered by the user's approach / touch, indicating that the vehicle door unlocking is the user's demand.

[0134] It should be noted that a detector can be used to detect the distance between the object outside the vehicle and the vehicle exterior, and in order to avoid the influence of rainwater causing false positives of the detector, an infrared sensor, a laser radar, or other instruments that are not easily affected by the weather are often used as the detector.

[0135] In some embodiments, the vehicle is provided with an infrared sensor, which is used to detect the distance between the object outside the vehicle and the vehicle exterior by detecting the infrared radiation emitted by the object under various weather conditions to obtain vehicle-object distance data. The infrared sensor sends the vehicle-object distance data to a MDC (Mobile Data Center), the MDC sends the vehicle-object distance data to a body domain controller, the body domain controller obtains the distance between the object outside the vehicle and the vehicle exterior based on the received vehicle-object distance data, and compares the distance with the second distance range to determine whether there is an object within the second distance range outside the vehicle.

[0136] Optionally, the infrared sensor can detect the object outside the vehicle in real time, or can start detecting the object outside the vehicle after receiving a detection instruction sent by the body domain controller. The detection instruction is sent by the body domain controller before controlling the corresponding door of the inductive capacitive sensor to be unlocked.

[0137] Optionally, the MDC sends a cyclic redundancy check code to the body domain controller at the same time as sending the vehicle-object distance data to the body domain controller. After receiving the vehicle-object distance data and the cyclic redundancy check code sent by the MDC, the body domain controller checks the vehicle-object distance data based on the cyclic redundancy check code to determine whether the received vehicle-object distance data is valid. After determining that the received vehicle-object distance data is valid, the body domain controller executes the step of determining whether there is an object in the second distance range outside the vehicle based on the received vehicle-object distance data. In this way, the accuracy of the judgment of the body domain controller on whether there is an object in the second range outside the vehicle can be ensured.

[0138] In some embodiments, the infrared sensor sends vehicle-object distance data to the MDC, the MDC determines whether there is an object in the second distance range outside the vehicle based on the vehicle-object distance data, and sends an identification signal to the body domain controller, the identification signal indicating whether there is an object in the second distance range outside the vehicle. In this case, the body domain controller can determine whether there is an object in the second distance range outside the vehicle based on the received identification signal.

[0139] For example, assuming that at the code level, the MDC and the body domain controller use ADS_ObstclDst to represent "whether there is an object in the second distance range outside the vehicle", use the value 0x0 to represent "there is no object in the second distance range outside the vehicle", and use the value 0x1 to represent "there is an object in the second distance range outside the vehicle". When the MDC determines that there is no object in the second distance range outside the vehicle, ADS_ObstclDst = 0x0. The MDC sends "0x0" as an identification signal to the body domain controller. After receiving "0x0" sent by the MDC, the body domain controller can determine that there is no object in the second distance range outside the vehicle.

[0140] In addition to the above method, other methods can also be used to determine whether there is an object in the second distance range outside the vehicle, and the embodiments of the present application do not limit this.

[0141] In some embodiments, after the second time length of shielding the electric release request triggered by the inductive capacitive sensor, the shielding state is exited, and steps 201-203 are re-executed.

[0142] The second time length is set in advance, and the specific size of the second time length is not limited in the embodiments.

[0143] In the embodiment of the present application, by comprehensively analyzing the motion state of the vehicle, whether the vehicle is in a car washing mode, the rainfall level of the external environment of the vehicle, whether the remote key of the vehicle is in the vicinity of the vehicle, and the like, the operation of controlling the unlocking of the door is performed only in the case that the inductive capacitive sensor is fault-free, the vehicle is not in a motion state, the vehicle is not in a car washing mode, the rainfall level of the external environment of the vehicle indicated by the rainfall level of the external environment of the vehicle is small, the inductive capacitive sensor triggers an electric release request, and the remote key of the vehicle is located within the first distance range of the vehicle. In the case that the vehicle is in a motion state, or the vehicle is in a car washing mode, or the rainfall level of the external environment of the vehicle indicated by the rainfall level of the external environment of the vehicle is large, or the remote key of the vehicle is not in the vicinity of the vehicle, even if the inductive capacitive sensor triggers an electric release request, the operation of controlling the unlocking of the door is not performed. That is, the embodiment of the present application determines whether to control the unlocking of the door by combining multiple comprehensive judgments, which can avoid the dangerous situation of the opening of the door of the vehicle in the process of the vehicle, and can also avoid the situation of the accidental opening of the door due to the rain touching the door handle when the user has no demand to open the door, thereby ensuring the safety of the user in the vehicle and improving the user experience of using the vehicle.
