Description

Technical Field

[0001] This application relates to the field of automotive technologies, and in particular, to an automotive auxiliary control method, system, device, and storage medium. Background Art

[0002] Currently, more and more people choose to travel by vehicle, and there are also more and more vehicles on the road, making the driving scenarios increasingly complex. Moreover, users' requirements for vehicle intelligence are also getting higher and higher. For example, some vehicles are equipped with an electric tailgate, and users can issue a tailgate opening command to achieve automatic opening of the tailgate, improving the convenience of vehicle use.

[0003] In related technologies, during actual research, it is found that due to the large volume of the electric tailgate, sufficient space is required at the rear when it is deployed. If the user is not careful, the tailgate will directly collide with an obstacle (such as the wall of a garage) when it is opened, causing property damage. In current market models, Hall sensors for monitoring the rotational speed and stroke of the drive motor are provided in the electric strut of the electric tailgate. When the tailgate encounters an obstruction, the Hall sensor sends a signal to the controller, and the controller controls the drive motor to stop working through the controller to avoid serious collisions of the tailgate and reduce losses. However, this method can only reduce losses. In actual applications, collisions still occur. If collisions are to be avoided, the user needs to stop the action of closing the tailgate in a timely manner, with a low level of intelligence, resulting in a poor user experience.

[0052] The present application will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments. The described embodiments should not be construed as limiting the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0053] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art belonging to the technical field of the present application. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0055] Currently, more and more people choose to travel by vehicle, and there are more and more vehicles on the road, making the driving scenario increasingly complex. Moreover, users' requirements for vehicle intelligence are also getting higher and higher. For example, some vehicles are equipped with an electric tailgate, and users can issue a tailgate opening command to achieve the automatic opening of the tailgate, improving the convenience of vehicle use.

[0056] In the related art, during actual research, it is found that due to the large volume of the electric tailgate, sufficient space needs to be reserved behind when it is deployed. If the user is not careful and the tailgate directly collides with an obstacle (such as the wall of a garage) when it is opened, it will cause property losses. In current market models, a Hall sensor for monitoring the rotational speed and stroke of the drive motor is provided in the electric strut of the electric tailgate. When the tailgate encounters an obstacle, the Hall sensor sends a signal to the controller, and the controller controls the drive motor to stop working to avoid serious collisions of the tailgate and reduce losses. However, this method can only reduce losses. In actual applications, collisions will still occur. If collisions are to be avoided, the user needs to stop the action of closing the tailgate in time, with a low degree of intelligence, resulting in a poor user experience.

[0057] In view of this, an automotive auxiliary control method is provided in the embodiments of the present application. This method uses the existing rear bumper radar of the vehicle to detect the distance to the obstacle, calculates the opening angle of the electric tailgate by identifying the distance, and controls the opening action of the tailgate, thereby reducing the risk of collision. The method in the embodiments of the present application only requires minor changes on the basis of the existing automotive hardware conditions. While reducing the development and production costs, it can make the opening of the electric tailgate more intelligent and more worry-free for users.

[0058] First, please refer to Figure 1 , Figure 1It is a traditional automotive rear parking radar system in the related art, namely the rear bumper radar. The rear bumper radar is mainly used to monitor obstacles around the vehicle during reverse parking. If there is a collision risk, it will alarm and notify the driver to prevent collisions. The radar applies the principle of ultrasonic ranging system. It emits ultrasonic waves and receives the reflected echoes. The time difference t between the two is obtained through the single-chip microcomputer counter, and the distance is calculated using the formula S = Ct / 2, where S is the distance between the vehicle and the obstacle, and C is the propagation speed of sound waves in the medium. Specifically, referring to Figure 1 , in this system, generally two groups of radars 2 are included, which are respectively arranged on the left and right sides behind the vehicle 3, and are used to detect the distances from both ends of the vehicle to the rear obstacles.

[0059] However, for the traditional automotive rear bumper radar, the radar only detects and alarms in real time according to the distance when the vehicle detects the ignition signal and the R gear signal. During the actual opening process of the electric tailgate 1, the vehicle is often in the N gear or P gear state, and at this time the radar is not triggered, and the radar and the tailgate are independent of each other. If a new detection radar is established separately to realize the detection and automatic control of the opening of the automotive tailgate, it will increase the production and manufacturing cost of the vehicle and waste the existing monitoring components.

[0060] Therefore, in the embodiments of the present application, a circuit connection relationship is established between the electric tailgate and the rear bumper radar, and a new control method is provided to achieve that during the opening process of the electric tailgate, taking the distance signal detected by the radar as the input, autonomously controlling the opening angle of the electric tailgate, and preventing the risk of collision of the tailgate.

[0061] Specifically, please refer to Figure 2 , in the embodiments of the present application, the vehicle includes a radar, a tailgate controller, and a ranging processor. The radar is used to detect the distance data between the vehicle and the rear obstacle. The ranging processor includes an input end and an output end. The input end is used to receive a ranging instruction, and the output end is used to output the detected distance data. The vehicle includes a reverse signal end, a parking signal end, a neutral signal end, an ignition signal end, and a tailgate opening signal end. The ignition signal end and the reverse signal end are connected to a first OR gate through a first AND gate, and the first OR gate is connected to the input end. The parking signal end and the neutral signal end are connected to a second AND gate through a second OR gate. The tailgate opening signal end is connected to the second AND gate, and the second AND gate is connected to the first OR gate.

[0062] In the embodiment of the present application, in the original rear bumper radar signal processing and control input circuit of the provided radar system, a logical OR gate (N gear or P gear and PTG start switch) is added. When the conditions are met, a first ranging command will be triggered, and the radar will actively range the obstacle. Subsequently, when the subsequent ranging processor receives the distance data transmitted by the radar, it will transmit this data to the tailgate controller (PTG UNIT) so that the tailgate controller can realize the automatic opening control of the vehicle tailgate according to the detected distance data.

[0063] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of an automotive auxiliary control method provided by an embodiment of the present application. Referring to Figure 3 , this automotive auxiliary control method includes but is not limited to:

[0064] Step 110: When the vehicle receives a tailgate opening command, the tailgate opening signal terminal triggers an electrical signal to the second AND gate;

[0065] In this step, when the user wants to open the vehicle tailgate, a tailgate opening command can be issued. When the vehicle receives the tailgate opening command, it starts to execute the tailgate opening task. Specifically, in some embodiments, the user can issue a tailgate opening command through the vehicle key. For example, a corresponding button can be set on the vehicle key, and when the user presses this button, the vehicle can obtain the tailgate opening command through communication. In other embodiments, the vehicle can also be configured with a voice recognition function. For example, a central control screen can be set on the vehicle, and the vehicle can realize the interaction with the user based on the central control screen. At this time, the voice data of the user can be obtained, and the voice data can be subjected to voice recognition to obtain various commands issued by the user. For example, when the user says "open the tailgate", it can be regarded as a tailgate opening command. When the vehicle recognizes this voice information, it can be considered that it has received the tailgate opening command.

[0066] In this step, when the vehicle receives the tailgate opening command, it can be considered that the user has issued a signal to open the tailgate. At this time, the tailgate opening signal terminal can trigger an electrical signal to the second AND gate. It can be understood that in the embodiment of the present application, the triggered electrical signal can be a voltage signal of a certain level, and this voltage signal can cause the corresponding logic gate circuit to act. For example, when there are voltage signals at both input terminals of the second AND gate, it achieves the AND logic, and an electrical signal can be output at its output terminal; if there is only one input terminal or no input terminal of the second AND gate has a voltage signal, it does not meet the AND logic and does not output an electrical signal. For other AND gates and OR gates, their logics are similar and will not be elaborated here.

[0067] Step 120: If the vehicle is currently in a parked state, the parking signal terminal triggers an electrical signal to the second AND gate; or, if the vehicle is currently in a neutral state, the neutral signal terminal triggers an electrical signal to the second AND gate.

[0068] In this step, when the user triggers the tailgate opening instruction, the tailgate of the vehicle is not immediately opened. Instead, the running state of the vehicle needs to be comprehensively judged. For example, when the vehicle is in a driving state, if the user accidentally triggers the tailgate opening instruction, it is very likely that items will fall when the tailgate is opened, resulting in losses or even collision accidents. Therefore, in the embodiment of the present application, only when it is confirmed that the vehicle is in a parked state or a neutral state, the automatic opening task of the tailgate is triggered.

[0069] Specifically, at the circuit level, the current running state of the vehicle is detected, and an electrical signal is triggered at the second AND gate only when the vehicle is in a parked state or a neutral state. For example, if the vehicle is currently in a parked state, then an electrical signal is triggered to the second AND gate through the parking signal terminal; or, if the vehicle is currently in a neutral state, then an electrical signal is triggered to the second AND gate through the neutral signal terminal. Of course, as long as one of these two situations is satisfied, the electrical signal trigger at the second language gate can be achieved. Therefore, the parking signal terminal and the neutral signal terminal are connected to the second AND gate through an OR gate. In the embodiment of the present application, the OR gate connecting the parking signal terminal and the neutral signal terminal is denoted as the second OR gate.

[0070] Step 130: The second AND gate triggers an electrical signal to the first OR gate, so that the first OR gate triggers a first ranging instruction to the input terminal;

[0071] In this step, when the second AND gate receives the electrical signal from the second OR gate and the electrical signal triggered by the tailgate opening signal terminal, the output terminal of the second AND gate will trigger an electrical signal to the first OR gate. When the first OR gate receives the electrical signal triggered by the second AND gate, it can be confirmed that the tailgate opening task needs to be performed currently, and the obstacles at the rear end of the vehicle need to be ranged. Therefore, a ranging instruction will be triggered. In the embodiment of the present application, it is the first ranging instruction. When the first test instruction is triggered, the first test instruction is sent to the input terminal of the ranging processor.

[0072] Step 140: In response to the first ranging instruction, the ranging processor obtains the distance data detected by the radar and transmits it to the tailgate controller;

[0073] In this step, the first ranging instruction can inform the ranging processor that the tailgate opening task is currently being performed. Therefore, the ranging processor can obtain the distance data detected by the radar and transmit the distance data to the tailgate controller.

[0074] Specifically, as described above, the radar in the embodiments of the present application may include a first radar and a second radar. The first radar is installed on the left side of the vehicle and can detect the distance data of the obstacle at the rear end on the left side of the vehicle. In the embodiments of the present application, this is the first distance data. Similarly, the second radar is installed on the right side of the vehicle and can detect the distance data of the obstacle at the rear end on the right side of the vehicle. In the embodiments of the present application, this is the second distance data. In the ranging processor, the specific distance data to be transmitted to the tailgate controller can be detected and distinguished.

[0075] It can be understood that for the tailgate opening task, if there are obstacles at both the left end and the right end of the vehicle tailgate, then the opening angle of the tailgate needs to be determined by relying on the obstacle that is closer in distance to ensure that it will not hit the obstacle. Therefore, in the embodiments of the present application, when the ranging processor sends the distance data, it can compare the first distance data and the second distance data, determine the smaller one of them as the target distance data, and then transmit the target distance data to the tailgate controller, thereby realizing the safe opening of the tailgate.

[0076] Step 150: The tailgate controller receives the distance data and controls the opening angle of the tailgate according to the distance data.

[0077] In this step, after receiving the distance data, the tailgate tester can control the opening angle of the tailgate according to the distance data, thereby realizing the safe, automated, and convenient opening of the tailgate.

[0078] Specifically, please refer to Figure 4 , in some embodiments, the controlling the opening angle of the tailgate according to the distance data includes:

[0079] According to the distance data, calculate the target opening angle of the tailgate through the following formula:

[0080]

[0081] In the formula, α is the target opening angle of the tailgate, θ is the angle between the line connecting the rotation center of the tailgate and the end of the tailgate in the closed state and the vertical plane, AD is the distance data, and OA is the length of the line connecting the rotation center of the tailgate and the end of the tailgate;

[0082] Control the tailgate to open to within the target opening angle.

[0083] In the embodiments of the present application, refer to Figure 4, when the vehicle tailgate 1 is opened, the tailgate 1 can be rotated by the electric strut 4 to open the tailgate 1. Specifically, the target opening angle when opening the tailgate can be determined by the distance data. In the embodiment of the present application, the target opening angle is the angle at which the tailgate opens when it just touches the obstacle 5 at the rear end. This angle can be calculated based on the detected distance data and the structure of the vehicle itself. In the embodiment of the present application, no specific limitations are imposed on the specific vehicle model and the tailgate structure.

[0084] It should be noted that the target opening angle is the angle corresponding to when the vehicle tailgate just touches the obstacle. It can be understood that in fact, we do not want the tailgate to collide. Therefore, when controlling, the tailgate needs to be opened to an angle within the target opening angle. Specifically, it can be to any angle value less than the target opening angle, for example, it can be an angle obtained by subtracting 5 degrees or 3 degrees from the target opening angle, and the embodiment of the present application does not limit this.

[0085] Specifically, in some embodiments, controlling the tailgate to open to an angle within the target opening angle includes:

[0086] Determine the maximum opening duration according to the target opening angle and the rotational angular velocity of the tailgate;

[0087] Control the tailgate to open, and control the tailgate to stop rotating before the opening duration reaches the maximum opening duration.

[0088] In the embodiment of the present application, generally speaking, when the vehicle tailgate starts, its rotational angular velocity is fixed. Therefore, when controlling it to open to an angle within the target opening angle, first, a maximum opening duration can be determined according to the target opening angle and the rotational angular velocity of the tailgate. The maximum opening duration is the opening duration corresponding to when the tailgate just touches the rear obstacle. Then, the opening of the tailgate can be controlled by the electric strut, and the opening duration starting from the original closed state is recorded. Before the opening duration reaches the maximum opening duration, control the tailgate to stop rotating, so as to avoid collision and safely complete the automatic opening of the tailgate.

[0089] It can be understood that the vehicle auxiliary control method provided in the embodiment of the present application uses the existing rear bumper radar of the vehicle to detect the distance of the obstacle, calculates the opening angle of the electric tailgate by identifying the distance, and controls the opening action of the tailgate, thereby reducing the risk of collision. The method in the embodiment of the present application only needs to be slightly changed based on the existing vehicle hardware conditions, which can reduce the development and production costs, make the opening of the electric tailgate more intelligent, and make the user more worry-free.

[0090] In some embodiments, the method further includes:

[0091] When the vehicle receives a reverse instruction, the ignition signal terminal and the reverse signal terminal trigger an electrical signal to the first OR gate through the first AND gate, so that the first OR gate triggers a second ranging instruction to the input terminal.

[0092] In the embodiments of the present application, it is also possible to implement reverse ranging based on Figure 2 the radar system. When the user reverses the vehicle, the vehicle receives a reverse instruction. At this time, the ignition signal terminal and the reverse signal terminal will trigger an electrical signal, and trigger an electrical signal to the first OR gate through the first AND gate. The first OR gate transmits a second ranging instruction to the ranging processor, informing the ranging processor that reverse operation is currently required. The distance data obtained by the ranging processor can be transmitted to the warning device, and reverse warning can be achieved by judging the size of the distance data.

[0093] The embodiments of the present application further provide an automotive auxiliary control system. The vehicle includes a radar, a tailgate controller, and a ranging processor. The radar is used to detect the distance data between the vehicle and the rear obstacle. The ranging processor includes an input terminal and an output terminal. The input terminal is used to receive a ranging instruction, and the output terminal is used to output the detected distance data. The vehicle includes a reverse signal terminal, a parking signal terminal, a neutral signal terminal, an ignition signal terminal, and a tailgate opening signal terminal. The ignition signal terminal and the reverse signal terminal are connected to the first OR gate through the first AND gate, and the first OR gate is connected to the input terminal. The parking signal terminal and the neutral signal terminal are connected to the second AND gate through the second OR gate, the tailgate opening signal terminal is connected to the second AND gate, and the second AND gate is connected to the first OR gate;

[0094] The system includes:

[0095] a receiving unit, configured to, when the vehicle receives a tailgate opening instruction, the tailgate opening signal terminal triggers an electrical signal to the second AND gate;

[0096] a detecting unit, configured to, if the vehicle is currently in a parked state, the parking signal terminal triggers an electrical signal to the second AND gate, or, if the vehicle is currently in a neutral state, the neutral signal terminal triggers an electrical signal to the second AND gate;

[0097] a triggering unit, configured to make the second AND gate trigger an electrical signal to the first OR gate, so that the first OR gate triggers a first ranging instruction to the input terminal;
