Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a method and device for generating a door control instruction, a vehicle-mounted system, and a vehicle. Background Art

[0002] Touch switches have replaced conventional mechanical switches as door lock control switches in vehicles due to their smaller footprint, refined design, and simpler installation. To unlock a vehicle door, the user touches the touch switch. Once the capacitance detected by the touch switch reaches a set value, the touch switch generates an unlock command to unlock the door.

[0003] While touch switches offer the advantages mentioned above, they can also be easily misactivated due to limitations in their detection principles. For example, if the touch switch is a capacitive touch switch, rainwater may splash onto the capacitive touch surface in rainy or snowy weather or during a car wash, causing the detected capacitance change to reach the set value, resulting in misactivation of the touch switch.

[0004] To address the aforementioned issues, related technologies have proposed combining capacitance change detection with temperature sensor detection to determine whether to generate an on command. However, due to the hysteresis of temperature sensor detection and the significant impact of ambient temperature on temperature change detection, the reliability and usability of this combined capacitance change and temperature change detection approach are limited.

[0048] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0049] The method for generating a door control instruction provided by the embodiment of the present disclosure, in addition to collecting the first trigger signal generated by the door touch switch, also performs feature detection on the layout of objects in the vehicle's surrounding environment to obtain environmental feature data, and then determines whether to generate a door control instruction based on the first trigger signal and the environmental feature data.

[0050] Figure 1 This is a flow chart of the method for generating a door control command provided by an embodiment of the present disclosure. Figure 1 As shown, the method for generating a door control instruction provided by the embodiment of the present disclosure includes S110-S130.

[0051] The method for generating a vehicle door control instruction provided by an embodiment of the present disclosure is executed by a controller installed in a vehicle and controlling a door lock switch.

[0052] S110: Acquiring environmental feature data in response to receiving a first trigger signal generated by a vehicle door touch switch.

[0053] The door touch switch is a switch installed on the door for detecting the user's touch action. In a specific implementation, the door touch switch can be a switch that detects touch actions based on various touch detection principles.

[0054] In some embodiments, the door touch switch is a capacitive switch, which determines whether a touch operation is received by way of capacitance detection.

[0055] In some other embodiments, the door touch switch is a resistance switch, which determines whether a touch operation is received by means of resistance detection.

[0056] In some further embodiments, the door touch switch is an infrared light reflection touch switch, which determines whether a touch operation is received by detecting reflected light.

[0057] The door touch switch may generate a first trigger signal upon detecting a touch operation. Furthermore, in other situations, such as when rainwater or insects adhere to the surface of the door touch switch, the door touch switch may be mistakenly triggered and generate the first trigger signal. Regardless of the reason for the touch switch to generate the first trigger signal, the door touch switch will transmit the first trigger signal to the controller, so that the controller receives the first trigger signal.

[0058] After receiving the first trigger signal generated by the door touch switch, the controller will obtain environmental feature data. The environmental feature data includes feature data generated by the environmental feature sensor collecting the layout features of objects in the vehicle's surrounding environment.

[0059] In some embodiments, the environmental feature sensor is a camera, and the corresponding environmental feature data is image data captured by the camera.

[0060] In some other embodiments, the environmental feature sensor is a lidar, and the corresponding environmental feature data is point cloud data collected by the lidar.

[0061] It should be noted that, in the embodiment of the present disclosure, the acquired environmental characteristic data should be environmental characteristic data acquired in a time period close to the moment of receiving the first trigger signal, so that the environmental characteristic data and the first trigger signal are correlated.

[0062] In some embodiments, when the first trigger signal is received, the environmental feature sensor has not yet been started, and the controller needs to trigger the initialization of the environmental feature sensor, and collect data to obtain environmental feature data after the initialization of the environmental feature sensor is completed.

[0063] In some other embodiments, the environmental feature sensor continuously collects environmental feature data. After receiving the first trigger signal generated by the door touch switch, the environmental feature sensor uses the environmental feature data collected at the corresponding moment as subsequent processing data.

[0064] S120: Determine whether there is a person in the target area associated with the door touch switch based on the environmental feature data.

[0065] The target area associated with the door touch switch is the area around the vehicle's perimeter that is adjacent to the door touch switch. In practice, the target area is determined based on the height and arm length of a typical user and the vehicle's door dimensions.

[0066] To determine whether there are people in the target area based on environmental feature data, the environmental feature data is processed using a data processing method corresponding to the environmental feature data, and the position information of the objects relative to the vehicle in the environmental feature data is extracted. Then, whether there are people in the target area is determined through the position information of the target area and the position information of the objects, as well as the type information of the objects.

[0067] In some embodiments, the environmental feature data is image data captured by a camera. In this case, determining whether a person is present in a target area based on the environmental feature data can involve processing the environmental feature data using a pre-trained neural network model, extracting attribute information and location information of objects in the environmental feature data, and determining whether a person is present in the target area based on the attribute information and location information.

[0068] In other embodiments, the environmental feature data is point cloud data collected by a laser radar. In this case, to determine whether a person is present in the target area based on the environmental feature data, a point cloud aggregation algorithm can be used to aggregate the point cloud located in the target area. The overall characteristics of the aggregated point cloud can then be used to determine whether the object characteristics conform to the anatomy of the human body. If the overall characteristics of the power source conform to the anatomy of the human body, the presence of a person in the target area is determined.

[0069] S130: Generate a door control instruction when it is determined that there is a person in the target area.

[0070] In the embodiment of the present disclosure, the door control instruction may be a door unlock instruction or a door lock instruction, and needs to be determined according to the current locking state of the door.

[0071] When the first trigger signal generated by the door touch switch is received and it is determined based on the environmental feature data that there is a person in the target area, the controller determines that the first trigger signal is generated by the person in the target area touching the touch switch, that is, the person has the intention to trigger the door to unlock or lock, and therefore generates a door control instruction.

[0072] The method for generating a door control command provided in an embodiment of the present disclosure, upon receiving a first trigger signal generated by a door touch switch, determines whether a person is present in the target area associated with the door touch switch based on environmental feature data acquired during a nearby time period. If a person is present in the target area, a door control command is generated. In other words, the method provided in an embodiment of the present disclosure generates a door control command only when the method receives a first trigger signal generated by the door touch switch and when a person is present in the target area associated with the door touch switch.

[0073] The method for generating door control instructions provided by the embodiment of the present disclosure is based on the situation that in the door opening and closing scenario, there must be a person in the target area associated with the door touch switch to trigger the door touch switch to generate a first trigger signal. After receiving the first trigger signal, the door control instruction will be generated only when it is determined that there is a person in the target area. In actual applications, the hardware resources equipped with the vehicle equipment can obtain environmental feature data in a very short time, and process the environmental feature data to determine whether there is a person in the target area, and thus quickly determine whether to generate a door control instruction. That is, the solution provided by the embodiment of the present disclosure will not take a long time due to the limitations of the physical principles of the detection method. In addition, the solution of the embodiment of the present disclosure will not be affected by factors such as ambient temperature. In other words, the method for generating door control instructions provided by the embodiment of the present disclosure has high usability.

[0074] Figure 2 This is a flow chart of a method for generating a door control command provided by some other embodiments of the present disclosure. Figure 2 As shown, in some other embodiments, the method for generating a door control instruction includes S210-S240.

[0075] In an embodiment of the present disclosure, the door touch switch in the vehicle includes a capacitive touch switch, and the corresponding trigger signal is a capacitance value.

[0076] S210: Acquire environmental feature data in response to receiving a first trigger signal generated by a door touch switch.

[0077] As in the previous embodiment, the environmental feature data is data generated by the environmental feature sensor collecting layout features of objects in the vehicle's surrounding environment.

[0078] S220: Determine whether there is a person in the target area associated with the capacitive touch switch based on the environmental feature data; if so, execute S230; if not, execute S210.

[0079] The execution process of the aforementioned S210-S220 is the same as that of the previous embodiment S110-S120, and will not be repeated here. Please refer to the previous description for details.

[0080] S230: Determine whether a second capacitance value generated by the capacitive touch switch is received after a preset time period; if so, execute S240; if not, execute S210.

[0081] S240: Generate door control instructions.

[0082] In the embodiment of the present disclosure, when it is determined that there is a person in the target area associated with the capacitive touch switch, the door control instruction is not directly generated. Instead, an additional determination condition is added, and the door control instruction is generated only when the additional determination condition is met.

[0083] Specifically, the controller also determines whether a second capacitance value generated by the capacitive touch switch has been received after a preset time period. This preset time period is determined based on extensive empirical data and is the duration of a user's contact with the capacitive touch switch when touching it. The preset time period is longer than the duration of a random scan across the capacitive touch switch. In one specific application, the preset time period is set to 0.3 seconds.

[0084] In actual scenarios, the user may perform some operations around the vehicle and quickly scan the capacitive touch switch, but at this time the user has no intention of opening or closing the door, that is, there is no intention to trigger the generation of the door control command.

[0085] For example, during a car wash, a car washer might be wiping the car body within the target area and their body or a wet towel might touch the capacitive touch switch. Another example is when someone passes through the target area and accidentally touches the capacitive touch switch. Using the methods provided in the previous embodiments can lead to the problem of false triggering of door control commands in these scenarios.

[0086] To avoid the aforementioned issues, the disclosed embodiment determines whether a second capacitance value generated by the capacitive touch switch has been received after a preset time period. If the second capacitance value is received, it is determined that the person in the target area did not touch the capacitive touch switch accidentally, but rather continuously. In this case, it is determined that the person has a strong intention to operate the vehicle door, and therefore a door control command is generated.

[0087] By adopting the above-mentioned method S210-S240, in addition to achieving the effects of the above-mentioned S110-S130, by adding additional judgment conditions, the probability of accurately generating the door control command can be further improved compared with the above-mentioned embodiment.

[0088] It should be noted that, in actual applications, the aforementioned S220 and S230 may be executed in a reversed order or simultaneously, and only needs to confirm that both judgment conditions are true to execute S240 to generate the door control instruction.

[0089] The door touch switch used in this embodiment is a capacitive touch switch. In other embodiments, the door touch switch may also be other types of switches, such as a resistance detection switch or a light reflection switch.

[0090] In some application scenarios, such as a car wash, a car washer might accidentally touch a capacitive touch switch while wiping the car body and then leave, but this could leave water droplets on the capacitive touch switch. These water droplets could still trigger the capacitive touch switch to generate a second capacitance value. Thus, even with the aforementioned S210-S240, there is a certain probability of falsely triggering the generation of a door control command. To further reduce the probability of falsely triggering the generation of a door control command, the controller can also execute the following S250-S260 before executing S240.

[0091] S250: Calculate the approximation between the first capacitance value and the second capacitance value.

[0092] In a specific implementation, the controller may use various methods to calculate the approximation between the first capacitance value and the second capacitance value.

[0093] In some embodiments, the controller may directly calculate the capacitance difference between the first capacitance value and the second capacitance value, and use the capacitance difference to represent the absolute similarity between the two.

[0094] In some other embodiments, the controller may calculate the relative ratio of the capacitance difference between the first capacitance value and the second capacitance value, and use the relative ratio to represent the relative similarity between the first capacitance value and the second capacitance value. The approximation s is calculated, where a is the first capacitance value and b is the second capacitance value. That is, in some embodiments, the controller calculates the absolute value and average value of the difference between the first capacitance value a and the second capacitance value b, and then calculates the ratio of the absolute value of the difference to the average value, and uses the above ratio as the approximation s. For example, in one application, the first capacitance value is 0.09pF and the second capacitance value is 0.11pF, then the calculated approximation is 0.2. In another application, the first capacitance value is 0.09pF and the second capacitance value is 0.095PF, then the calculated approximation is 0.054.

[0095] Of course, in actual applications, other methods may be used to calculate the approximation between the first capacitance value and the second capacitance value, which will not be given as examples here.

[0096] S260: Determine whether the approximation meets the set conditions; if so, execute S240.

[0097] In a specific implementation, determining whether the approximation satisfies a set condition may be performed by determining whether the approximation is less than a threshold value of approximation. For example, when the calculated approximation is a relative approximation, the relative approximation may be compared with a set relative approximation threshold to determine whether it is less than the relative approximation threshold. If the relative approximation is less than the set relative approximation threshold, S240 may be executed to generate a door control instruction. In a specific application, the approximation threshold is set to 0.1. Based on this approximation threshold, when the approximation between the first capacitance value and the second capacitance value is 0.2, S240 is not executed to generate a door control instruction. However, when the approximation between the first capacitance value and the second capacitance value is 0.054, S240 is executed to generate a door control instruction.

[0098] In actual applications, when a user touches a capacitive touch switch, the contact area during the touch process will not change significantly, and the corresponding first and second capacitance values should be relatively close. However, the capacitance values formed by the user touching the capacitive touch switch and the water droplet falling on the capacitive touch switch will be quite different. In other words, using S250-S260 can eliminate the possibility that factors such as water droplets may cause the second capacitance value to be received later, thereby causing the door control command to be falsely triggered.

[0099] In actual applications, in addition to executing the aforementioned S250-S260 when the car door touch switch is a capacitive touch switch, the aforementioned S250-S260 can also be executed when the car door touch switch is a touch switch such as a resistive touch switch that can output corresponding detection values.

[0100] Figure 3 This is a flow chart of a method for generating a door control command according to some other embodiments of the present disclosure. Figure 3 As shown, in the embodiment of the present disclosure, the method for generating a door control instruction includes S310-S340.

[0101] S310: Acquire environmental feature data in response to receiving a first trigger signal generated by a vehicle door touch switch.

[0102] S320: Determine whether there is a person in the target area associated with the door touch switch based on the environmental feature data; if so, execute S330; if not, execute S310.

[0103] The execution process of the aforementioned S310-S320 is the same as that of the previous embodiment S110-S120, and will not be repeated here. Please refer to the previous description for details.

[0104] S330: Determine whether the person's posture is the target posture based on the environmental feature data; if so, execute S340; if not, execute S310.

[0105] S340: Generate door control instructions.

[0106] Different from the previous embodiments, in the embodiment of the present disclosure, when it is determined that there is a person in the target area, the controller does not directly generate a door control instruction, but further processes the environmental feature data to extract the posture of the person in the target area.

[0107] In a specific implementation, if the environmental feature data is image data, the controller can use a pre-trained neural network model to process the environmental feature data and determine the person's posture. If the environmental feature data is point cloud data, the controller can use a point cloud aggregation algorithm to aggregate the point cloud located in the target area to determine the person's posture. In a specific implementation, the person's posture can be represented by the angle of the person's torso, the angle of the upper limbs, and the angle between the torso and upper limbs.

[0108] In the disclosed embodiment, the target posture is a typical posture of a user when operating a door touch switch. In a specific implementation, the target posture includes the typical postures of the user's upper limbs and torso. The typical posture can be represented by the angle range of the user's upper limbs, the angle range of the torso, and the angle range between the torso and the upper limbs. The angle range of the user's upper limbs can be 30 to 60 degrees, the angle range of the torso is 80 to 100 degrees (it should be noted that the aforementioned angle range of the user's upper limbs and the angle range of the torso are both relative to the horizontal plane), and the angle range between the torso and the upper limbs is 20-70 degrees.

[0109] Determining whether the person's posture is the target posture based on the environmental feature data can involve determining whether the angles corresponding to the person's posture are within the angle range corresponding to a typical posture. If the person's posture is the target posture, it is determined that the user intended to operate the door touch switch. At the same time, if it is determined that the first trigger signal generated by the door touch switch has been received, it is determined that the user is likely to have operated the door touch switch, and therefore a door control instruction is generated.

[0110] In some embodiments, when it is determined that there is a person in the target area associated with the door touch switch, the following S350 may also be executed.

[0111] S350: Determine whether the detection distance from the person to the door touch switch is less than a set distance based on the environmental characteristic data.

[0112] Determining the detection distance between a person and the door touch switch based on environmental feature data involves processing the environmental feature data using a corresponding method based on the type of environmental feature data to determine the detection distance. Once the detection distance is determined, it can be determined whether the detection distance is less than the set distance.

[0113] The set distance is a pre-set, smaller distance that represents the typical distance between the center of a user's hand or wrist and the vehicle door when touching a door touch switch. In practice, the typical distance can be set slightly larger than the actual distance. If the detection distance is less than the set distance, it is determined that the user has approximately touched the door touch switch.

[0114] When it is determined that the detection distance is less than the set distance during S350 , S340 may be executed to generate a door control instruction.

[0115] Here is an additional explanation: S330 and S350 in the disclosed embodiment do not conflict with S230 and S250-S260 mentioned above. In actual application, S330, S230 and S250-S260 can be executed simultaneously, and the door control command is generated only when all conditions are met.

[0116] As previously mentioned, environmental feature data is acquired in response to receiving a first trigger signal generated by a door touch switch. In practice, after the vehicle is unlocked, the controller wakes up the door touch switch, causing it to begin testing to determine whether the first trigger signal has been generated.

[0117] In addition to providing the aforementioned method for generating a vehicle door control instruction, an embodiment of the present disclosure also provides a device for generating a vehicle door control instruction. Figure 4 Schematic diagram of a device for generating a door control command according to an embodiment of the present disclosure. Figure 4 As shown, the door control instruction generating device 400 includes a data acquisition unit 401 , a data processing unit 402 and a control unit 403 .

[0118] The data acquisition unit 401 is used to acquire environmental feature data in response to receiving a first trigger signal generated by the door touch switch. The environmental feature data includes data generated by the environmental feature sensor collecting layout features of objects in the vehicle's surrounding environment.

[0119] The data processing unit 402 is configured to determine whether there is a person in the target area associated with the vehicle door touch switch based on the environmental feature data.

[0120] The control unit 403 is configured to generate a door control instruction when it is determined that there is a person in the target area.

[0121] In some embodiments, after receiving the first trigger signal, the data acquisition unit 401 determines whether a second trigger signal is received after a preset time period; the control unit 403 generates a door control instruction when it determines that there is a person in the target area and receives the second trigger signal.

[0122] In some embodiments, the door touch switch includes a capacitive touch switch; the data acquisition unit 401 acquires environmental characteristic data in response to receiving a first capacitance value generated by the capacitive touch switch; the data processing unit 402 determines whether a second capacitance value generated by the capacitive touch switch is received after a preset time period.

[0123] In some embodiments, when the second capacitance value is received after a preset time period, the data processing unit 402 calculates the approximation between the first capacitance value and the second capacitance value, and determines whether the approximation satisfies a set condition;
