[0058] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0059] It should be noted that in the description of the present application, "multiple" is understood as "at least two". The association relationship of "and / or" describing the associated objects means that there can be three relationships, for example, A and / or B can represent the three cases of A existing alone, A and B existing together, and B existing alone. A is connected with B, which can represent two cases: A is directly connected with B and A is connected with B through C. In addition, in the description of the present application, "first", "second", and the like are used only for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor indicating or implying order.

[0060] In addition, in the technical solutions of the present application, the collection, transmission, use, etc. of data all comply with the requirements of relevant national laws and regulations.

[0061] The design idea of the embodiments of the present application is as follows:

[0062] In the prior art, the information interaction of the electric safety belt controller is usually based on the vehicle bus CAN, for example, as shown in FIG. 1, the vehicle system (such as the advanced driving assistance system ADAS or the passive safety system PSS) and the electric safety belt controller are connected through the vehicle bus CAN to perform information interaction, and the interaction information includes motion posture, vehicle speed, braking, acceleration, and safety belt action indication. Figure 1

[0063] However, on the one hand, the development complexity of the CAN bus is usually high, so based on the above-mentioned manner, it is easy to cause more consumption of human resources and hardware resources, on the other hand, it is necessary to perform logic conversion according to the bus transceiver, which brings additional hardware cost.

[0064] In order to reduce the development cost and hardware requirement of data transmission between the domain controller and the electric safety belt controller, the embodiments of the present application provide an electric safety belt control method and device, electronic equipment and storage medium, the domain controller obtains the action information of the target scene for the electric safety belt controller, and generates the corresponding action instruction according to the action information, and after the action instruction is transmitted to the electric safety belt controller through the hard line, the control result is obtained based on the received state information of the electric safety belt controller.

[0065] ​Based on the above manner, the application adopts the hard wire between the domain controller and the electric safety belt controller for data transmission. Compared with the communication mode based on the CAN bus, the above manner avoids the additional consumption of human resources and hardware resources caused by the high development complexity. Meanwhile, the bus transceiver is not needed, which further reduces the hardware demand required for data transmission. Further, since the control signal transmitted by the hard wire is relatively simple (i.e., high and low levels), compared with the bus communication, the above manner also improves the stability of system data transmission.

[0066] Further, based on the above design idea, the electric safety belt control method provided by the application can be applied to but not limited to any vehicle with an electric safety belt, such as a car or an intelligent driving vehicle. Taking the intelligent driving vehicle as an example, referring to FIG. 2, it is shown that the intelligent driving vehicle can be equipped with an electric safety belt control system. The electric safety belt control system includes a vehicle driving system 201, a domain controller 202, an electric safety belt controller 203, and an electric safety belt 204. Figure 2

[0067] The vehicle driving system 201 is used for perceiving the target environment in which the vehicle is located, and transmitting the perceived environment information to the domain controller 202 through the vehicle bus. The vehicle driving system 201, such as the intelligent driving system of the vehicle.

[0068] The domain controller 202 is used for receiving the environment information and / or perceiving the target environment by itself, calculating the control logic for the electric safety belt to generate the corresponding control instruction, and transmitting the control instruction to the electric safety belt controller 203 through the hard wire. Optionally, the domain controller can be the airbag controller of the vehicle, and the control instruction corresponding to the target environment can be generated by the computer program deployed in the domain controller.

[0069] The electric safety belt controller 203 is used for receiving the control instruction transmitted by the domain controller 202 through the hard wire, and controlling the electric safety belt of the vehicle in response to the control instruction to obtain the control result.

[0070] The electric safety belt 204 is used for implementing the safety belt action indicated by the control instruction, and feeding back the control result (such as the running state, etc.) to the electric safety belt controller 203.

[0071] In an optional embodiment, the hard wire transmission can be understood as the data transmission created between the domain controller 202 and the electric safety belt controller 203 through the hard wire, such as the transmission by using the pulse width modulation (PMW) wave. In the data transmission, the domain controller 202 sends the control instruction generated for the target environment to the electric safety belt controller. Since the development complexity required by the hard wire is relatively low, the above manner can effectively reduce the development cost required for data transmission.​

[0072] In an optional embodiment, after obtaining the control result, the electric safety belt controller returns the resistance value combination representing the control result to the domain controller 202 through hard-wire transmission in the form of a corresponding resistance value combination. The transmission carrier of the resistance value combination, for example, includes a pulse width modulation (PMW) wave, so that the domain controller 202 can monitor the running state of the electric safety belt 204 in real time, which is conducive to the upgrading and maintenance of the system.

[0073] Based on the above application scenarios, the electric safety belt control method provided by the embodiments of the present application will be further described and explained in combination with the accompanying drawings. Referring to FIG. 1, the electric safety belt control method provided by the embodiments of the present application includes the following steps: Figure 3

[0074] S301: For the electric safety belt controller, obtain the action information of the target scene.

[0075] S302: According to the action information, generate a corresponding action instruction, and transmit the action instruction to the electric safety belt controller through hard-wire transmission, so that the electric safety belt controller controls the electric safety belt according to a control action indicated by the action instruction, and generates state information according to a control result.

[0076] S303: Receive the state information transmitted by the electric safety belt controller through hard-wire transmission, and obtain the control result.

[0077] Specifically, the action information indicates that the electric safety belt controller triggers a control action, that is, according to the control functions defined by the electric safety belt controller, determines the control action to be performed by the electric safety belt controller on the electric safety belt in each action scene; optionally, the target scene can be perceived by other vehicle devices (such as vehicle driving systems) associated with the domain controller and obtained through bus transmission, or can be perceived and calculated by the domain controller itself.

[0078] For example, in the embodiments of the present application, according to one or more action scenes that may trigger the electric safety belt action, each control function to be executed by the electric safety belt controller on the electric safety belt in each action scene is defined artificially and / or through a related model, wherein each control function is associated with an action identifier in a preset action identifier set, and each action identifier can be used for a control action of the electric safety belt controller. Specifically, as shown in Table 1 below:

[0079] Table 1

[0080]

[0081] ​Belt Parking, Belt Slack Reduction, FCW / AEB / FCTA / TJP belt activation, RCTA belt activation, RCTA belt activation, RCW belt activation, Haptic Warning for DPS.

[0082] Further, in the embodiments of the present application, one of the action scenarios as shown above, which is perceived by the current vehicle driving system or domain controller, is taken as a target scenario, and from the action identifier set (1-4), the action identifier associated with the target scenario is taken as the action information of the target scenario, so as to generate the corresponding action instruction according to the action information.

[0083] In an alternative embodiment, a pulse width modulation signal (PMW) is used for hard-wire transmission, that is, the signal carrier of the PMW wave is taken as the action instruction transmitted by the domain controller and the electric safety belt controller through the hard-wire, specifically, according to the action information of the target scenario, a target modulation frequency corresponding to the action information is obtained from a preset modulation frequency set, and a pulse width modulation signal matching the target modulation frequency is taken as the action instruction to be transmitted.

[0084] For example, for each action identifier shown in Table 1 above, the corresponding modulation frequency is shown in Table 2 as follows:

[0085] Table 2

[0086] Action identification Action description Modulation frequency (Hz) Control action 1 Pretension with 250N for least 3s 200 1 2 Pretension with 140N for least 3s 100 2 3 Vibrate with 50N and 5Hz for least 3s 50 3 4 Pretension with 20N for least 3s 20 4

[0087] In the above, the Chinese interpretation of the action description is as follows: Pretension with 250N for least 3s, Pretension with 140N for least 3s, Vibrate with 50N and 5Hz for least 3s, Pretension with 20N for least 3s.

[0088] It can be seen that in the embodiment of the application, the action information corresponding to the perceived target environment is transmitted to the electric safety belt controller through the hard line by using the pulse width modulation (PMW) wave, thereby ensuring normal transmission of data.

[0089] Further, in an optional embodiment, after the domain controller transmits the action instruction to the electric safety belt controller, the electric safety belt controller acquires a resistance value combination of a plurality of resistors associated with the electric safety belt according to a control result, and generates state information through the resistance value combination, and then the domain controller can confirm the control result of the electric safety belt according to the resistance value combination after receiving the state information.

[0090] For example, the embodiment of the application uses different resistance value combinations of the following resistors associated with the electric safety belt: Switch 1 and Switch 2, which reflect different control results (for example, a plurality of possible working states of the electric safety belt) of the electric safety belt controller in the process of controlling the electric safety belt, as shown in Table 3 below:

[0091] Table 3

[0092]

[0093] Among them, R1, R2, R3, R4, R5 and R6 are six resistance values set for the resistors Switch 1 and Switch 2 respectively.

[0094] It can be seen that based on the above method, the electric safety belt controller transmits the resistance value combination representing the control result to the domain controller through the hard line, so that the domain controller can timely confirm the working state of the electric safety belt and troubleshoot according to the control result, thereby ensuring the user experience.

[0095] Further, based on the same design idea, the embodiment of the application also provides another electric safety belt control method, which can be applied to the electric safety belt controller, as shown in Figure 4 , which includes:

[0096] S401: receiving an action instruction transmitted by a domain controller through a hard line.

[0097] S402: controlling the electric safety belt according to a control action indicated by the action instruction, and generating state information according to a control result.

[0098] S403: transmitting the state information to the domain controller through the hard line, so that the domain controller obtains the control result based on the state information.

[0099] Specifically, the action instruction is generated according to action information of a target scene, and the action information indicates that the electric safety belt controller triggers a control action.

[0100] For example, in an embodiment of the present application, the electric safety belt controller can receive the action instruction generated by the domain controller through hard-wire transmission, which is transmission through a pulse width modulation (PMW) wave. The electric safety belt controller controls the electric safety belt according to the received action instruction and generates state information.

[0101] In an alternative embodiment, the electric safety belt controller obtains a resistance value combination of a plurality of resistors associated with the electric safety belt according to the control result and generates state information carrying the resistance value combination.

[0102] For example, in an embodiment of the present application, the electric safety belt controller obtains a resistance value combination of the following resistors associated with the electric safety belt: Switch 1 and Switch 2, and generates state information carrying the resistance value combination. The ohmic range to which the resistance value combination can belong can be shown in Table 3 above, which will not be described here again.

[0103] It can be seen that the electric safety belt control method provided in an embodiment of the present application receives the action instruction corresponding to the action information of the target scene generated by the domain controller, controls the electric safety belt according to a control action indicated by the action instruction, and generates state information according to the control result. The state information is transmitted to the domain controller through hard-wire transmission, so that the domain controller obtains the control result based on the state information. Based on the above method, data transmission is performed through the hard-wire between the domain controller and the electric safety belt controller. On the one hand, the additional consumption of human resources and hardware resources caused by the high development complexity during the development of the CAN bus is avoided. On the other hand, the bus transceiver required for logical conversion is cancelled, and the hardware requirement for data transmission is further reduced.

[0107] The acquisition module 503 is configured to receive the state information transmitted by the electric safety belt controller through the hard line, and obtain the control result.

[0108] In an optional embodiment, the action information of the target scene is acquired, and the action module 501 is specifically configured to:

[0109] In response to the target scene perceived by the domain controller, an action identifier associated with the target scene is determined from a preset action identifier set as the action information of the target scene, wherein each action identifier indicates one control action of the electric safety belt controller.

[0110] Alternatively,

[0111] In response to the scene information sent by the vehicle driving system through the bus, the target scene indicated by the scene information is determined, and an action identifier associated with the target scene is determined from a preset action identifier set as the action information of the target scene.

[0112] In an optional embodiment, the action instruction corresponding to the action information is generated, and the transmission module 502 is specifically configured to:
