[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of the application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0026] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0027] In the following description, the terms "first," "second," and "third" are used only to distinguish different objects and do not represent a specific order of objects, nor are they constituting a chronological order. It is understood that "first," "second," and "third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0029] This application provides a control method, apparatus, device, and storage medium for electric vehicle doors. In practical applications, the control method for electric vehicle doors can be implemented by a control device for electric vehicle doors. The functional entities in the control device for electric vehicle doors can be collaboratively implemented by the hardware resources of electronic devices (such as terminal devices), such as computing resources like processors and communication resources (such as those used to support various communication methods like optical fiber and cellular networks).

[0030] The following describes various embodiments of the electric vehicle door control method, device, equipment, and storage medium provided in this application.

[0031] In a first aspect, embodiments of this application provide a control method for an electric vehicle door, which is applied to a control device for the electric vehicle door. The functions implemented by this method can be achieved by a processor in the vehicle equipment calling program code. Of course, the program code can be stored in a computer storage medium. Therefore, the vehicle equipment includes at least a processor and a storage medium.

[0032] The control method for electric vehicle doors provided in the embodiments of this application will be described below.

[0033] Figure 1 This is a flowchart illustrating the control method for an electric vehicle door according to an embodiment of this application, as shown below. Figure 1 As shown, the process may include, but is not limited to, S101 to S104 below.

[0034] S101. Vehicle Equipment: Determine the vehicle safety integrity level of the electric doors of the vehicle equipment.

[0035] In one possible implementation, the vehicle safety integrity level can be divided into: first safety level, second safety level, third safety level, fourth safety level, and fifth safety level.

[0036] For example, vehicle safety integrity levels can be divided into five levels: QM, A, B, C, and D. Among them, ASIL D is the highest vehicle safety integrity level, with the highest requirements for functional safety.

[0037] For example, the safety integrity level of the electric door here can be Class B.

[0038] S102. When the vehicle's safety integrity level is greater than or equal to the third safety level, the vehicle equipment activates the first function.

[0039] The first function is used to prevent the electric vehicle door from being opened abnormally.

[0040] For example, when the ASIL level of the electric door is 1, the first function is activated to prevent abnormal opening of the electric door.

[0041] The activation here can be either automatic by default or activated manually.

[0042] S103. In response to the first function, the vehicle equipment detects a first parameter of the vehicle equipment in its current state when it determines that it has received the request to open the electric door.

[0043] The "Open Door Request" is used to request the opening of any electric vehicle door. This can be used to request the opening of a single electric vehicle door or to request the opening of all electric vehicle doors.

[0044] The opening request for an electric vehicle door can be triggered by a button, facial recognition, voice, or other methods.

[0045] In one possible implementation, the opening request for the electric door is an opening request triggered from inside the vehicle.

[0046] In another possible implementation, the opening request for the electric door could be an opening request generated by a system malfunction.

[0047] The first parameter is used to help determine whether the request to open is an abnormal request. This application embodiment does not limit the specific type of the first parameter and can be configured according to actual circumstances.

[0048] S104. If the first parameter meets the first condition, the vehicle equipment shall prohibit the opening of the electric vehicle door.

[0049] Meeting the first condition indicates that the request to open the electric vehicle door is an abnormal opening request.

[0050] Denying abnormal opening requests for electric vehicle doors can improve their security level.

[0051] The restriction on opening doors can be achieved by using the Body Domain Controller (BDC) to restrict all doors, or by using the individual drive control unit (DCU) of each door to restrict opening their doors.

[0052] The electric door control method provided in this embodiment of the application includes: determining the vehicle safety integrity level of the electric door of the vehicle equipment; activating a first function when the vehicle safety integrity level is greater than or equal to a third safety level; the first function is used to prevent abnormal opening of the electric door; in response to the first function, detecting a first parameter of the vehicle equipment in its current state when it is determined that an opening request for the electric door has been received; prohibiting the opening of the electric door when the first parameter satisfies a first condition; and indicating that the opening request for the electric door is an abnormal opening request when the first condition is satisfied.

[0053] The solution in this application enables a first function based on the ASIL level. This first function is used to prevent abnormal opening of the electric door. Specifically, upon receiving an opening request for the electric door, a first parameter of the current state of the vehicle equipment is detected. Based on whether the first parameter meets a first condition, the opening request is determined to be an abnormal opening request. For abnormal opening requests, opening the electric door is prohibited. It can be seen that this solution reduces the probability of abnormal opening of the electric door, improves the security of the vehicle equipment, meets the requirements of the electric door for the vehicle's safety integrity level, and is simple to implement.

[0054] The following describes the process by which the vehicle equipment in S104 prevents the opening of the electric door.

[0055] This process may include, but is not limited to, method 1 or method 2 below.

[0056] Method 1: The vehicle equipment prevents the opening of all doors of the vehicle equipment through the Body Domain Controller (BDC).

[0057] Specifically, the vehicle equipment outputs a first-level signal through the BDC; the first-level signal is used to control all doors of the vehicle equipment to close.

[0058] For example, the first level signal can be a high level signal.

[0059] For example, vehicle equipment outputs a high level based on internal safety mechanisms via BDC; or, for example, the output level is forcibly pulled high via a System Basis Chip (SBC) with functional safety rating.

[0060] Method 2: The vehicle equipment determines the target door corresponding to the opening request; the drive control unit (DCU) of the target electric door prevents the target door from being opened.

[0061] The target DCU is the DCU that controls the target door.

[0062] In practice, each electric door corresponds to a unique DCU.

[0063] When an opening request corresponds to a single electric door, the target door corresponding to the opening request is first determined from among multiple doors, and the opening of the target electric door is prohibited by the DCU of the target electric door.

[0064] For example, the target DCU sends a shutdown command to prevent the target door from being opened.

[0065] When all electric vehicle doors corresponding to the request are opened, all electric vehicle doors are simultaneously prohibited from being opened via all DCUs.

[0066] As can be seen, compared with method 2, method 1 can control all electric doors through a single BDC, which is simple to implement.

[0067] Compared with method 1, method 2 can be flexibly controlled for different electric doors, and has the characteristic of flexible implementation.

[0068] The first parameter and the first condition will be explained below.

[0069] In one possible implementation, the first parameter includes: driving speed;

[0070] Correspondingly, the first condition includes: the driving speed is greater than or equal to the first speed threshold.

[0071] This application does not limit the value of the first speed threshold, and it can be configured according to actual needs. For example, the first speed threshold can be 3 kilometers per hour.

[0072] It can be seen that opening the electric door while the vehicle is in motion is prone to accidents, so opening requests at speeds exceeding the first speed threshold are considered abnormal opening requests.

[0073] In another possible implementation, the first parameter includes: gear information;

[0074] Correspondingly, the first condition includes: the gear information is a non-parking gear.

[0075] It can be seen that a normal request to open an electric door usually occurs when the vehicle is in the park position. Therefore, if the vehicle is not in the park position, any request to open the electric door will be considered an abnormal opening request.

[0076] In another possible implementation, the first parameter includes: fault information of the BDC;

[0077] Correspondingly, the first condition includes: the existence of BDC fault information.

[0078] BDC fault information may include, but is not limited to, random hardware failures or systemic failures. For example, clock failures or communication failures.

[0079] Understandably, a startup request in a fault state can be considered an abnormal startup request.

[0080] In practice, the three detection parameters and three conditions can be used in combination based on actual needs. Furthermore, the first parameter and the first condition can also be other parameters and conditions used to detect whether it is an abnormal opening request of the electric door, which will not be listed here.

[0081] The electric vehicle door control method provided in this embodiment will issue an alarm when the first parameter meets the first condition, that is, when the electric vehicle door opening request is an abnormal opening request.

[0082] refer to Figure 2 The process may include, but is not limited to, S105 below.

[0083] S105. When the first parameter meets the first condition, the vehicle equipment outputs a fault alarm through BDC.

[0084] The fault alarm is used to indicate that there is a request to open the electric vehicle door abnormally.

[0085] The fault alarm can be output before, after, or at the same time as the prohibition of opening the electric vehicle door.

[0086] This application does not limit the specific method of outputting fault alarms, and can be configured based on actual conditions.

[0087] In one possible implementation, the vehicle equipment outputs alarm information via BDC in the form of voice; and / or in the form of text; and / or in the form of light.

[0088] For example, a voice message can be broadcast stating, "There is a request to open the electric vehicle door abnormally."

[0089] For example, the message "There is an abnormal request to open the electric vehicle door" can be displayed.

[0090] For example, an indicator light can be used to warn of an abnormal request to open the electric vehicle door.

[0091] The following describes the control method for electric vehicle doors provided in the embodiments of this application through a complete process.

[0092] Let me first give a brief introduction to some of the concepts.

[0093] Functional Safety Background: Vehicle safety is a topic of great concern to everyone, and every traffic accident results in significant losses. As people's demand for a comfortable driving experience continues to grow, automotive electronic systems are becoming increasingly complex, and the risks caused by electrical and electronic system failures are also increasing. With cars now almost ubiquitous in households, the sheer number of vehicles and their high frequency of use place higher demands on electrical and electronic systems. As of the end of June 2018, according to data released on July 16, 2018, the number of motor vehicles in China reached 319 million. The driving failure rate is 1-99.99999%, meaning that approximately 310,000 vehicles may experience malfunctions.

[0094] A car is an extremely large and complex system. A typical car has over 10,000 parts and more than 100 Electronic Control Units (ECUs). How to integrate these 10,000+ parts and 100+ ECUs in an orderly manner and meet the ever-increasing demands for comfortable driving is a significant challenge for the automotive industry. The failure of any one of these parts, or even an ECU, can lead to irreparable damage. Therefore, how to quantitatively assess the safety of automotive functions, how to reduce and mitigate risks, and how to achieve functional safety in automobiles have become extremely important issues.

[0095] Functional safety: There is no unreasonable risk caused by malfunction of the electronic or electrical system.

[0096] Electric car doors: The motor is driven by a controller to open and close the car door. They are aesthetically pleasing, convenient, and greatly improve our quality of life.

[0097] ASIL level definition: To assess and quantify the risks posed by failure in order to achieve safety objectives, its full name is Automotive Safety Integration Level. Generally, hazard analysis and risk assessment are conducted during the product concept design phase to identify system hazards. The greater the safety risk of the system, the higher the corresponding safety requirement level, and the higher its ASIL level. ASIL is divided into five levels: QM, A, B, C, and D. ASIL D is the highest automotive safety integrity level, with the highest requirements for functional safety.

[0098] Hazard analysis and risk assessment of the electric door resulted in an ASIL level of B. Therefore, the design of the electric door system requires higher standards than traditional designs, and it is necessary to consider how to handle malfunctions of the electric door to reduce or avoid risks during driving.

[0111] Performing a functional safety analysis yields a summary of safety objectives and a selection of functional safety requirements. The summary of safety objectives is shown in Table 3 below.

[0112] Table 3 Example of a summary of safety objectives

[0113]

[0114] The functional safety requirements can be selected as shown in Table 4 below.

[0115] Table 4 Example of excerpts from functional safety requirements

[0116]

[0117] The problem this embodiment aims to solve is traffic accidents caused by electric vehicle door malfunctions (unexpected opening, possibly due to random hardware failure or systemic failure).

[0118] The adopted technical solution includes: introducing speed and gear as the judgment conditions for the opening and closing of electric doors, and assigning the requirement an ASIL B functional safety level, thereby controlling random hardware failures or systemic failures (causing the electric door to open unexpectedly during movement) within a reasonable range, and entering a safe state (prohibiting electric micro-opening and fault alarms) before the hazard occurs, thus reducing and avoiding the risks during driving.

[0119] Specifically, a functional safety design module has been added to the BDC, with the main functions including:

[0120] Input: speed or gear information.

[0121] Output: Hard-wired signal, driving the electric micro-opening motor to open or close the door lock ratchet (low level: door open; high level: door closed), causing the door to pop out at a certain angle due to the elasticity of the rubber strip.

[0122] When the vehicle speed is greater than 3 kilometers per hour (kph) or the "actual gear of the vehicle" is in a non-parking gear (non-P gear), the BDC will not perform electric micro-opening operation. Under unexpected execution conditions, the execution will be interrupted within 200 milliseconds (the output can be made high through the internal safety mechanism of the controller, for example, by forcibly pulling the output level high through an SBC chip with functional safety level).

[0123] For the specific control logic of the functional safety design module added inside the Body Domain Controller (BDC), please refer to [reference needed]. Figure 4 As shown in S401 to S406.

[0124] S401, Begin;

[0125] S402, Obtain the gear position signal from the VCU;

[0126] S403, Obtain vehicle speed signal from ESP;

[0127] S404. Determine if the vehicle speed is greater than 3 kph or if the "actual gear of the vehicle" is not in P gear;

[0128] If yes, proceed with S405 below; if no, proceed with S406 below.

[0129] S405. It is prohibited to open the electric vehicle doors;

[0130] S406, End.

[0131] The main core functions of this embodiment include:

[0132] From a functional safety perspective, higher requirements are placed on the design of electric door systems (meeting ASIL B), controlling random hardware failures or systemic failures (causing the electric door to open unexpectedly during operation) within a reasonable range.

[0133] The Body Domain Controller (BDC) determines whether the electric door is open reasonably based on the vehicle speed or the current gear. If it is not reasonable, it refuses to open the electric door slightly, thus preventing the electric door from opening.

[0134] If the Body Domain Controller (BDC) detects a fault in its own controller, it can use an internal safety mechanism to forcibly raise the output level before the fault occurs, thereby preventing the electric micro-opening. For example, this can be achieved by using an SBC chip with functional safety features to forcibly raise the output level.

[0135] This embodiment has the following technical effects:

[0136] 1) Introducing functional safety controls random hardware failures or systemic failures (causing the electric vehicle door to open unexpectedly during operation) within a reasonable range, thereby reducing and avoiding risks during driving.

[0137] 2) The vehicle speed signal and gear position signal are readily available signals and meet the functional safety requirements at the vehicle level (generally, the vehicle speed signal can achieve ASIL D and the gear position signal can achieve ASIL C at the vehicle level). This function can be implemented by simply adding a functional logic to the body domain controller (BDC). There are no additional requirements, which is beneficial for cost control.

[0138] 3) The main control unit (BDC) itself needs to implement a large number of ASIL B requirements. Therefore, adding an ASIL B requirement has minimal impact on the BDC. The functional safety-related management and functional safety development work can be packaged together. Compared to changing the development of four DCUs from QM to ASIL B, this greatly reduces costs and shortens the development cycle.

[0139] Functional safety requires strict adherence to functional safety procedures during development and places higher demands on both hardware and software. Developing a controller from one without functional safety to one with functional safety will significantly impact both cost and project timeline.
