[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes the safety control method, device, vehicle and storage medium of the vehicle intelligent driving of the embodiment of the present application with reference to the accompanying drawings. In view of the related art mentioned in the above background technology, because the front-view camera is often arranged under the windshield, it is affected by direct sunlight and the high heat generated by its own SOC chip, resulting in the multifunctional front-view camera often working abnormally due to overheating, increasing the damage rate of the front-view camera, and affecting the safety of the intelligent driving function. The present application provides a safety control method for vehicle intelligent driving, in which the temperature of the MCU chip and the SOC chip and the wheel speed information are monitored in real time to effectively monitor the fault of the multifunctional front-view camera, thereby improving the reliability and accuracy of intelligent driving and improving the safety of users during driving. Thus, the problem that the front-view camera is often arranged under the windshield, affected by direct sunlight and the high heat generated by its own SOC chip, resulting in the multifunctional front-view camera often working abnormally due to overheating, increasing the damage rate of the front-view camera, and affecting the safety of the intelligent driving function is solved.

[0029] Specifically, Figure 1 A flowchart of a method for controlling vehicle intelligent driving safety provided in an embodiment of the present application.

[0030] like Figure 1 As shown, the vehicle intelligent driving safety control method includes the following steps:

[0031] In step S101, when the multifunctional front-view camera of the vehicle enters at least one intelligent driving mode, the current MCU chip temperature and current wheel speed information of the multifunctional front-view camera are obtained.

[0032] It is understood that in the embodiment of the present application, the multifunctional front-view camera may be a camera integrated in the front of the vehicle, which is used to provide image information in front of the vehicle to realize various intelligent driving functions of the vehicle, such as adaptive cruise control, lane keeping assist, automatic parking, etc. The MCU chip may be a microcontroller unit integrated in the multifunctional front-view camera, and the current wheel speed information may be the current wheel speed of the vehicle.

[0033] In step S102, it is determined whether the multifunctional front-view camera meets the preset power-on safety conditions according to the current MCU chip temperature and the current wheel speed information.

[0034] It should be noted that the preset power-on safety conditions can be set by those skilled in the art according to actual conditions and are not specifically limited here.

[0035] It can be understood that in the embodiments of the present application, the preset power-on safety conditions can be limiting conditions set for the current MCU chip temperature and the current wheel speed information to ensure that the camera operates in a safe state. The current MCU chip temperature and the current wheel speed information are compared with the preset power-on safety conditions to determine whether the camera meets the safety startup conditions.

[0036] Optionally, in one embodiment of the present application, based on the current MCU chip temperature and the current wheel speed information, it is determined whether the multi-function front-view camera meets the preset power-on safety conditions, including: determining whether the current MCU chip temperature is less than or equal to a first temperature threshold; if the current MCU chip temperature is less than or equal to the first temperature threshold, then determining that the multi-function front-view camera meets the preset power-on safety conditions, otherwise, detecting whether the current MCU chip temperature is greater than the second temperature threshold.

[0037] In the actual implementation process, when the SOC is powered on for the first time, the temperature value of the current MCU chip can be read, and the read MCU chip temperature can be compared with the preset first temperature threshold. If the current MCU chip temperature is less than or equal to the first temperature threshold, it is determined that the multi-function front-view camera meets the preset power-on safety conditions, and the SOC chip can be powered on directly. If the current MCU chip temperature is greater than the first temperature threshold, the temperature check is further continued.

[0038] Optionally, in one embodiment of the present application, detecting whether the current MCU chip temperature is greater than a second temperature threshold includes: when the current MCU chip temperature is greater than the second temperature threshold, determining that the multi-function front-view camera does not meet the preset power-on safety conditions, generating corresponding function error information based on at least one intelligent driving mode, and controlling the vehicle to send the function error information using at least one interactive device; when the current MCU chip temperature is less than or equal to the second temperature threshold, determining whether the current wheel speed information is a valid value; if the current wheel speed information is a valid value, determining that the multi-function front-view camera meets the preset power-on safety conditions, otherwise, generating corresponding function error information based on at least one intelligent driving mode, and controlling the vehicle to send the function error information using at least one interactive device.

[0039] In the actual execution process, it can be determined whether the current MCU chip temperature is greater than the second temperature threshold. If the current MCU chip temperature is greater than the second temperature threshold, it is directly determined that the multifunctional front-view camera does not meet the preset power-on safety conditions. At this time, a corresponding function error message is generated based on at least one intelligent driving mode in which the multifunctional front-view camera participates, and the vehicle is controlled to use at least one interactive device, such as the vehicle's display screen or warning sound to send the function error message to notify the driver of a safety problem. If the current MCU chip temperature is less than or equal to the second temperature threshold, the wheel speed information is continued to be obtained and determined. If the current wheel speed information is a valid value, it is determined that the multifunctional front-view camera meets the preset power-on safety conditions and can be powered on and work normally. If the current wheel speed information is 0 or cannot be read, it is considered that there is a problem with the wheel speed sensor or other related components, and a corresponding function error message is generated based on at least one intelligent driving mode, and the function error message is sent through at least one interactive device.

[0040] In step S103, if the multifunctional forward-looking camera meets the preset power-on safety conditions, the SOC chip of the multifunctional forward-looking camera is controlled to be powered on, and based on the current SOC chip temperature matching the corresponding safety monitoring result, at least one safety protection action is generated according to the safety monitoring result, and the vehicle is controlled to perform at least one safety protection action.

[0041] It is understandable that in the embodiment of the present application, if the multifunctional front-view camera meets the preset power-on safety conditions, the SOC chip is controlled to be powered on, that is, the system-level chip that controls the overall function of the multifunctional front-view camera is powered on, so that the camera enters the working state. Then, the temperature of the SOC chip is continuously monitored and matched with the corresponding safety monitoring results. According to the safety monitoring results, at least one safety protection action will be generated, including warnings for over-high or under-temperature, etc., to ensure the normal use of the intelligent driving function and protect the safety of the vehicle and passengers.

[0042] Optionally, in one embodiment of the present application, based on matching the current SOC chip temperature with the corresponding safety monitoring result, at least one safety protection action is generated according to the safety monitoring result, including: detecting whether the current SOC chip temperature is greater than a third temperature threshold; if the current SOC chip temperature is greater than the third temperature threshold, then determining that the safety monitoring result is a high temperature hazard result, and generating a camera fault reminder and an intelligent driving mode fault reminder according to the high temperature hazard result, otherwise, determining that the safety monitoring result is a safe operation result.

[0043] In the actual implementation process, by comparing the current temperature of the SOC chip with the preset third temperature threshold, if the current SOC chip temperature is greater than the third temperature threshold, the safety monitoring result is determined to be a high temperature hazard result, and a camera fault reminder and an intelligent driving mode fault reminder are generated at this time, and the driver is notified through the vehicle's interactive equipment (such as display screen, sound prompt, etc.) to remind him to pay attention to possible camera failures and take necessary measures, such as turning off the intelligent driving mode. If the current SOC chip temperature is less than or equal to the third temperature threshold, the safety monitoring result is determined to be a safe operation result, which means that the SOC chip is operating within the normal temperature range.

[0044] Optionally, in one embodiment of the present application, after generating a camera fault reminder and an intelligent driving mode fault reminder based on a high temperature hazard result, it also includes: determining whether the current SOC chip temperature is greater than a fourth temperature threshold; if the current SOC chip temperature is greater than the fourth temperature threshold, then determining that the safety monitoring result is an over-temperature hazard result, and generating a SOC chip power-off action based on the over-temperature hazard result.

[0045] In the actual execution process, after the camera fault reminder and the intelligent driving mode fault reminder are generated according to the high temperature hazard result, the temperature of the SOC chip continues to be monitored and compared with the preset fourth temperature threshold. If the current SOC chip temperature is greater than the fourth temperature threshold, the safety monitoring result is determined to be an over-temperature hazard result. At this time, in order to prevent chip damage, the SOC chip power-off action will be executed to ensure that the chip will not be damaged by overheating. If the current SOC chip temperature is less than or equal to the fourth temperature threshold, the MCU chip temperature is continuously monitored. When it is lower than the second temperature threshold, or the SOC chip is turned off for more than 20 minutes, the SOC chip is powered on again.

[0046] The working content of the embodiment of the present application is described in detail below with a specific embodiment. Figure 2 This is a schematic diagram of the operation of the multifunctional front-view camera over-temperature detection and alarm scenario in one embodiment of the present application. Figure 3 This is a control logic diagram of over-temperature detection and alarm of a multifunctional front-view camera according to an embodiment of the present application. Figure 2It includes the first power-on scenario of the SOC chip and the power-on and running scenario of the SOC chip. Figure 3 It contains the control logic for the operation of the two scenarios. The multi-functional front-view camera FCM mainly includes SOC chips (such as J3 and EQ5), MCU chips, camera modules, and other electronic components. The temperatures in the SOC chip and the MCU chip are obtained at a 1s cycle. If the temperature exceeds the corresponding threshold three times in a row, it is determined that the corresponding event has occurred.

[0047] Among them, in the first power-on scenario of the SOC chip. When the multi-functional front-view camera FCM is powered on for the first time, the MCU receives the first power-on signal and sets the flag for the first power-on of the SOC, i.e., SOC_firstrun_flag = true. It monitors the temperature Tmcu of the MCU and the wheel speed information wheelspeed. The logic is as follows: If it is monitored that the temperature Tmcu of the MCU ≤ T1, the MCU powers on the SOC, and the flag bit for the first power-on of the SOC, SOC_firstrun_flag = false; If it is monitored that the temperature T1 < Tmcu ≤ T2, when wheelspeed = 0 or the wheel speed cannot be obtained, the MCU does not power on the SOC, and the MCU chip sends a signal indicating that the intelligent driving function is unavailable to the instrument for display; When wheelspeed!= 0, the MCU powers on the SOC, and the flag bit for the first power-on of the SOC, SOC_firstrun_flag = false; If it is monitored that Tmcu > T2, the MCU does not power on the SOC chip, and the MCU chip sends a signal indicating that the intelligent driving function is unavailable to the instrument for display.

[0048] In the power-on and running scenario of the SOC chip, during the normal operation after the SOC is powered on, it monitors the temperature Tsoc of the SOC in real time. The logic is as follows: If the Tsoc temperature exceeds T3, it reports an over-temperature fault of the FCM and exits the function. The MCU sends a fault signal and an unavailable signal to the instrument for prompting; If the Tsoc temperature exceeds T4, the MCU shuts down the SOC chip, reports an over-temperature fault of the all-in-one machine, and exits the function. The MCU sends a fault signal and an unavailable signal to the instrument for prompting. T1, T2, T3, and T4 are the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold respectively, which can be optimized and confirmed according to the test performance of the actual vehicle.

[0049] According to the vehicle intelligent driving safety control method proposed in the embodiment of the present application, the temperature of the MCU chip and the SOC chip and the wheel speed information can be monitored in real time to effectively monitor the fault of the multifunctional front-view camera, thereby improving the reliability and accuracy of intelligent driving and the safety of users during driving. Thus, the problem in the related art that the multifunctional front-view camera often works abnormally due to overheating, which increases the damage rate of the front-view camera and affects the safety of the intelligent driving function, is solved.

[0050] Next, the safety control device for intelligent driving of a vehicle proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0053] Among them, the acquisition module 100 is used to obtain the current MCU chip temperature and current wheel speed information of the multi-function front-view camera when the multi-function front-view camera of the vehicle enters at least one intelligent driving mode.

[0054] The judgment module 200 is used to judge whether the multifunctional front-view camera meets the preset power-on safety conditions according to the current MCU chip temperature and the current wheel speed information.

[0055] The control module 300 is used to control the SOC chip of the multi-function front-view camera to power on when the multi-function front-view camera meets the preset power-on safety conditions, and to match the corresponding safety monitoring results based on the current SOC chip temperature, generate at least one safety protection action according to the safety monitoring results, and control the vehicle to perform at least one safety protection action.

[0059] Optionally, in one embodiment of the present application, the determination unit is specifically used to: when the current MCU chip temperature is greater than a second temperature threshold, determine that the multi-function front-view camera does not meet the preset power-on safety conditions, generate corresponding function error information based on at least one intelligent driving mode, and control the vehicle to send the function error information using at least one interactive device; when the current MCU chip temperature is less than or equal to the second temperature threshold, determine whether the current wheel speed information is a valid value; if the current wheel speed information is a valid value, determine that the multi-function front-view camera meets the preset power-on safety conditions, otherwise, generate corresponding function error information based on at least one intelligent driving mode, and control the vehicle to send the function error information using at least one interactive device.

[0060] Optionally, in one embodiment of the present application, the control module 300 includes:

[0061] A detection unit, used to detect whether the current SOC chip temperature is greater than a third temperature threshold;

[0062] The reminder unit is used to determine that the safety monitoring result is a high temperature hazard result when the current SOC chip temperature is greater than a third temperature threshold, and generate a camera fault reminder and an intelligent driving mode fault reminder according to the high temperature hazard result; otherwise, the safety monitoring result is determined to be a safe operation result.

[0063] Optionally, in one embodiment of the present application, the reminder unit is specifically used to: after generating a camera fault reminder and an intelligent driving mode fault reminder based on a high temperature hazard result, determine whether the current SOC chip temperature is greater than a fourth temperature threshold; if the current SOC chip temperature is greater than the fourth temperature threshold, determine that the safety monitoring result is an over-temperature hazard result, and generate an SOC chip power-off action based on the over-temperature hazard result.

[0064] It should be noted that the aforementioned explanation of the embodiment of the vehicle intelligent driving safety control method is also applicable to the vehicle intelligent driving safety control device of this embodiment, and will not be repeated here.

[0065] According to the vehicle intelligent driving safety control device proposed in the embodiment of the present application, the temperature of the MCU chip and the SOC chip and the wheel speed information can be monitored in real time to effectively monitor the fault of the multifunctional front-view camera, thereby improving the reliability and accuracy of intelligent driving and the safety of users during driving. Thus, the problem in the related art that the front-view camera is often arranged under the windshield and is affected by direct sunlight and the high heat generated by its own SOC chip, resulting in the multifunctional front-view camera often working abnormally due to overheating, increasing the damage rate of the front-view camera and affecting the safety of the intelligent driving function is solved.
