Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to vehicle system upgrade methods, apparatus, equipment and storage media. Background Technology

[0002] When a user sets up an upgrade appointment, the vehicle system will be temporarily locked in upgrade mode and start a countdown when the appointment time is triggered. This countdown serves as a grace period during which the user can change the status to cancel, and the system will release resources and terminate the upgrade process accordingly.

[0003] Currently, the countdown duration is statically defined in the codebase as a fixed value, lacking dynamic configurability. This makes it difficult to adjust dynamically based on user feedback or market changes, and cannot guarantee compliance with actual needs. Furthermore, in the unattended operation mode of the vehicle intelligent system (DA), when the appointment upgrade process is triggered and enters the countdown state, if the system prematurely enters sleep mode due to energy-saving strategies during this period, the system services cannot automatically restore to the context before the interruption after the vehicle is powered on again. This will cause the tasks executed before the power outage to disappear, ultimately leading to the failure of the upgrade service. Summary of the Invention

[0020] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0022] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Based on this, embodiments of this application provide a vehicle system upgrade method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the vehicle system upgrade method of this application.

[0024] In this embodiment, the vehicle system upgrade method includes steps S10 to S40: Step S10: Determine the basic upgrade duration based on the upgrade package specifications.

[0025] It should be noted that the execution subject of this embodiment can be the vehicle itself or a vehicle system upgrade device installed in the vehicle. The vehicle system upgrade device can be a controller installed in the vehicle, such as an HMI (Human Machine Interface) controller, or other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the vehicle system upgrade device is used as an example to illustrate the vehicle system upgrade method of this application.

[0026] It should be noted that the upgrade package specification can be the size of the upgrade package to be downloaded when the upgrade is scheduled, and the basic upgrade duration can be the time required for the vehicle to download and install the upgrade package of this specification.

[0027] In actual use, the car manufacturer's server can send upgrade notifications to the vehicle. The user can choose not to upgrade immediately, but instead enable scheduled upgrade (such as scheduled upgrade at 9 pm). At this time, when the user's scheduled upgrade time is reached, the vehicle system upgrade device can execute step S10, determine the upgrade package specifications for this upgrade based on the previously received upgrade notification, and determine the basic upgrade duration based on the vehicle's hardware capabilities.

[0028] Step S20: Adjust the basic upgrade duration according to the upgrade influencing factors and generate an upgrade prompt duration.

[0029] In practical applications, the larger the upgrade package, the longer the upgrade takes. This means that users will be unable to use their vehicles for a longer period of time after the upgrade. Correspondingly, the grace period for users to make a decision needs to be longer. In other words, the longer the actual upgrade time, the longer the upgrade prompt time for users to decide whether to upgrade. Therefore, the basic upgrade time can be adjusted to generate an upgrade prompt time.

[0030] It should be noted that the factors affecting the upgrade can be any factors that may affect the upgrade speed or upgrade strategy during the upgrade process. Specifically, the factors affecting the upgrade can include one or more of the following: battery temperature, personnel factors, reminder time period, vehicle location, etc.

[0031] In a specific implementation, if the factor affecting the upgrade is battery temperature, then step S20 in this embodiment may include: Obtain vehicle battery temperature; The vehicle battery temperature is matched with each preset temperature range to determine the target temperature range; The duration adjustment value is determined based on the duration adjustment coefficient corresponding to the target temperature range and the basic upgrade duration. The upgrade prompt duration is constructed based on the duration adjustment value and the basic upgrade duration.

[0032] It should be noted that battery temperature affects vehicle performance. The efficiency of batteries and electronic devices will decrease or speed will be limited for protection under extreme temperatures. Therefore, battery temperature will affect the upgrade speed. Based on this, the vehicle battery temperature can be obtained, and then matched with various preset temperature ranges to determine the target temperature range. Then, the duration correction coefficient corresponding to the target temperature range is multiplied by the basic upgrade duration to generate a duration adjustment value. Finally, the duration adjustment value is added to the basic upgrade duration, and the sum is used as the upgrade prompt duration.

[0033] For example: Assuming the vehicle battery temperature is T, the base upgrade duration is BaseTime, and the duration adjustment value is TempAdjust, then: If 10°C ≤ T ≤ 35°C, the duration adjustment factor = 0, TempAdjust = 0. BaseTime=0 (Optimal temperature, no adjustment); If 0°C ≤ T < 10°C or 35°C < T ≤ 45°C, the duration adjustment factor is 20%, and TempAdjust = BaseTime. 20% (Unsuitable temperature, slight performance reduction, moderate increase in duration); If T < 0°C or T > 45°C, the duration adjustment factor = 50%, TempAdjust = BaseTime. 50% (Extreme temperatures, performance is significantly reduced, and duration is greatly increased).

[0034] In practical applications, at some more extreme temperatures, the battery or electronic devices may enter a protection state, making it unsuitable for upgrades. Due to this scenario, before matching the vehicle battery temperature with each preset temperature range, it is advisable to first determine whether the vehicle battery temperature is within the suitable temperature range for the upgrade. If it is, then the matching can proceed; otherwise, the scheduled upgrade can be terminated and a corresponding prompt can be given.

[0035] For example: First check whether T exceeds the safe operating range for vehicle upgrades (e.g., <-20°C or >60°C). If it does, the upgrade should be prohibited, and a message should be displayed saying "Ambient temperature is not suitable, upgrade cannot be performed". If it does not exceed the range, then T should be matched with each preset temperature range.

[0036] The number and specific range of the temperature ranges mentioned above are for illustrative purposes only and are not subject to specific restrictions. The number and range of the ranges can be adjusted according to actual needs, and this embodiment does not impose any restrictions on this.

[0037] In a specific implementation, if the influencing factor for the upgrade is a personnel factor, then step S20 in this embodiment may include: Check if there are any people using the vehicle; If present, check if the vehicle is in a parked state; If the vehicle is parked, obtain the personnel information of the user and their location inside the vehicle; The duration adjustment value is determined based on the personnel information and the location inside the vehicle; The upgrade prompt duration is constructed based on the duration adjustment value and the basic upgrade duration.

[0038] It should be noted that if there are no users in the vehicle, no additional processing is required; If there are people using the vehicle (i.e., people are in any seat in the vehicle), it is necessary to further check whether the vehicle is parked. If it is not parked, it means that the vehicle may be moving at this time. In order to avoid affecting the use of the vehicle, the upgrade can be prohibited and the message "Vehicle is in use, upgrade cannot start" can be displayed. If the vehicle is parked, in order to set a more reasonable reminder duration, we can further obtain the user's information and the vehicle's location, and then determine the duration adjustment value based on the user information and the vehicle's location.

[0039] For example: if the user is identified as a driver based on the personnel information, and the driver's seat is the vehicle's interior, it can be determined that the driver is briefly parking, and the duration adjustment value can be set to 0. If the user is identified as a driver based on the personnel information, and their position in the vehicle is not the driver's seat, it can be determined that the driver has been parked for an extended period of time. At this time, the driver may be resting or organizing items, and may have difficulty paying attention to the upgrade notification. In order to ensure that they can notice the upgrade notification, the duration adjustment value can be set to 5 minutes. If the user is determined to be a non-driver based on the personnel information, and their position in the vehicle is not the driver's seat, it can be determined that the driver has left the vehicle. In this case, the driver may not be able to notice the upgrade prompt. To ensure that the driver can notice the upgrade prompt, the duration adjustment value can be set to a longer value, such as 10 minutes.

[0040] The specific values ​​for duration adjustment in the examples above are for illustrative purposes only and are not intended to impose any specific restrictions.

[0041] In a specific implementation, if the influencing factor for the upgrade is the notification period, then step S20 in this embodiment may include: The current time is segmented and matched with preset time periods to determine the target time period; Determine the duration adjustment value based on the target time period; The upgrade prompt duration is constructed based on the duration adjustment value and the basic upgrade duration.

[0042] It should be noted that the preset time segmentation is based on the average network speed of each time period. For example, times with average network speeds in the same range are divided into the same time period.

[0043] In practical use, the current time can be matched with preset time segments, and the preset time segment to which the current time belongs can be used as the target time period.

[0044] In practical use, the ratio of the difference between the average network speed and the reference network speed corresponding to the target time period to the reference network speed can be calculated. This ratio can be multiplied by the basic upgrade duration, and the product can be used as the duration adjustment value.

[0045] The reference network speed can be the average network speed over a specific period (such as the average network speed between 7:00 and 23:00) or the lowest network speed.

[0046] For example: Suppose the average network speed for the current target time period is 10MB / s, the reference network speed is 7MB / s, and the basic upgrade duration is 20 minutes, then the duration adjustment value = 20. (10-7) / 7=8.57 minutes.

[0047] In practical applications, since it is difficult to obtain data for the current day, when dividing time periods and determining average network speed, historical network data from the previous week (or a shorter or longer period) in the area where the vehicle is located can be used for calculation and division.

[0048] It is understandable that the network may be smoother at certain times (such as between 0:00 and 6:00 at night), while it may be more congested at other times (such as between 11:00 and 1:00 when more people are using the network and it may be more congested). Based on this, the duration adjustment value can be determined according to the network speed difference at specific times.

[0049] In a specific implementation, if the upgrade influencing factor is vehicle location, step S20 in this embodiment may include: Determine the area where the vehicle is located based on its position; Obtain available upgrade servers in the area where the vehicle is located; The duration adjustment value is determined based on the available upgrade servers; The upgrade prompt duration is constructed based on the duration adjustment value and the basic upgrade duration.

[0050] It should be noted that the upgrade servers that can be used when a vehicle is in different regions are actually different. For example, in northern cities, the upgrade server used may be the North China server; in southern cities, the upgrade server used may be the South China server; and overseas, the upgrade server used may be the overseas server. In reality, different servers may have different data transmission capabilities. Gene Cluster can first match the vehicle's location with the coverage area of ​​each server to determine the available upgrade servers in the area where the vehicle is located. Then, based on the differences in data transmission capabilities of the available upgrade servers, set the corresponding duration adjustment value.

[0051] For example: if the available upgrade server corresponding to the area where the vehicle is located is the North China server, and the data transmission capability of the North China server is optimal, then the duration adjustment value can be set to 0; If the available upgrade server for the area where the vehicle is located is the South China server, and the data transmission capability of the South China server is only worse than that of the North China server, then the duration adjustment value can be set to 1 minute. If the available upgrade server for the area where the vehicle is located is a European server, and the data transmission capability of the European server is worse than that of the South China server, then the duration adjustment value can be set to 3 minutes. If the available upgrade server for the area where the vehicle is located is a North American server, and the North American server has the worst data transmission capability due to its greater distance, then the duration adjustment value can be set to 8 minutes.

[0052] The specific values ​​in the examples above are for illustrative purposes only and do not impose any specific limitations on the scheme. The specific values ​​for setting the duration adjustment can be adjusted according to actual needs, and this embodiment does not impose any restrictions on this.

[0053] In practical use, multiple upgrade influencing factors can be set simultaneously. The vehicle system upgrade equipment can collect data based on each upgrade influencing factor, estimate the impact on upgrade duration based on the collected data, generate corresponding duration adjustment values, and then add the duration adjustment values ​​corresponding to each upgrade influencing factor to the basic upgrade duration to generate the upgrade prompt duration.

[0054] To avoid the final upgrade notification duration being too short, the administrator of the vehicle system upgrade equipment can preset a minimum duration. If the duration generated by adjusting the basic upgrade duration based on upgrade influencing factors is less than the minimum duration, then the minimum duration will be used as the upgrade notification duration. If the duration generated by adjusting the basic upgrade duration based on upgrade influencing factors is greater than or equal to the minimum duration, then the adjusted duration will be used as the upgrade notification duration.

[0055] In practical implementation, to ensure the rationality of actual application (such as testing requirements or user personalization settings), relevant developers and users can be allowed to pre-set the upgrade prompt duration according to actual needs. At this time, the upgrade prompt duration can be comprehensively constructed based on the pre-set duration setting strategy, the pre-set duration by relevant developers and users, and the duration generated by adjusting the basic upgrade duration according to upgrade influencing factors.

[0056] The duration setting strategy can include various strategies such as coverage strategy, balanced strategy, and priority strategy.

[0057] If the duration setting strategy is an overriding strategy, the last duration set by the relevant developers and users can be used as the upgrade prompt duration. For example, if the relevant developers set the duration to 9:00 and the user set the duration to 9:01, then the duration set by the user can be used as the upgrade prompt duration.

[0058] If the duration setting strategy is a balanced strategy, then the duration preset by relevant developers and users can be weighted (e.g., weighted summation or weighted average) with the duration generated by adjusting the base upgrade duration based on upgrade influencing factors. This weighted duration is then used as the upgrade notification duration. For example, if the preset durations by relevant developers and users are A and B respectively, and the duration generated by adjusting the base upgrade duration based on upgrade influencing factors is C, then the upgrade notification duration = wa. A+wb B+wc C, where wa, wb, and wc can be pre-set weighting coefficients.

[0059] If the duration setting strategy is a priority strategy, then the priorities corresponding to the durations preset by relevant developers and users, and the durations generated by adjusting the basic upgrade duration based on upgrade influencing factors, can be obtained. The duration with the highest priority is used as the upgrade prompt duration. For example, if the durations preset by relevant developers and users are A and B respectively, and the duration generated by adjusting the basic upgrade duration based on upgrade influencing factors is C, and the priority is B > A > C, then the upgrade prompt duration is B.

[0060] Step S30: Control the vehicle to enter the scheduled upgrade state and start the timer.

[0061] In actual use, after determining the upgrade prompt duration, the vehicle can be controlled to enter the scheduled upgrade state, prompting the user that the upgrade is about to take place, and at the same time, the timer starts.

[0062] The timer can be a countdown timer, with the countdown duration matching the upgrade notification duration. This countdown can be displayed on the vehicle's screen to inform the user how much longer until the upgrade. Of course, the timer can also be a forward timer, depending on actual needs; this embodiment does not impose any restrictions on this.

[0063] When a vehicle enters the scheduled upgrade state, it will maintain a high voltage state and prevent any components in the vehicle from entering a dormant state. This is to ensure that the vehicle does not consume battery power, avoid the entire vehicle from running out of power, and prevent the upgrade from failing due to system state loss caused by the vehicle going into dormant mode.

[0064] In specific implementation, to reasonably avoid hibernation, the steps for controlling the vehicle to enter the scheduled upgrade state as described in this embodiment may include: Obtain the scheduled broadcast frequency; Control the high voltage on the vehicle and periodically broadcast a denial of hibernation statement at the scheduled broadcast frequency to cause the vehicle to enter the scheduled upgrade state.

[0065] It should be noted that the appointment broadcast frequency can be a fixed frequency preset by the administrator of the vehicle system upgrade equipment, for example, setting the appointment broadcast frequency to 1 second / time.

[0066] In practical use, when controlling the vehicle to enter the scheduled upgrade state, a request for high voltage can be sent to the vehicle's power system to control the vehicle to enter the high voltage state. At the same time, a refusal to hibernate statement is periodically broadcast to each component in the vehicle at the scheduled broadcast frequency, prohibiting the components in the vehicle from entering the hibernation state, thereby controlling the vehicle to enter the scheduled upgrade state.

[0067] In practical applications, when in the scheduled upgrade state, the vehicle system upgrade equipment can also periodically detect the operating mode of the vehicle's power system to maintain a high voltage. The detection cycle for the power system can be set at the scheduled broadcast frequency, or at a higher or lower frequency; this embodiment does not impose any restrictions on this.

[0068] Step S40: When the timer reaches the upgrade prompt duration, control the vehicle to perform a vehicle system upgrade.

[0069] Understandably, when the upgrade prompt duration is reached, it can be assumed that the user has given permission to upgrade. Therefore, the vehicle system can be upgraded. At this time, an immediate upgrade command can be sent to the Client, and the Client will then execute the upgrade. At this time, the vehicle system upgrade equipment can no longer maintain various restrictions of the scheduled upgrade state (such as high voltage, hibernation restrictions, etc.) and instead hand over control to the Client for subsequent operations.

[0070] The Client can be a client in the vehicle that performs system upgrades.

[0071] If a countdown timer is used, the timer can be determined to have reached the upgrade prompt duration when the timer counts to 0; if a forward timer is used, the timer can be determined to have reached the upgrade prompt duration when the timer counts to match the upgrade prompt duration.

[0072] This embodiment provides a vehicle system upgrade method. Since the basic upgrade duration can be determined according to the upgrade package specifications and dynamically adjusted according to the upgrade influencing factors, an upgrade reminder duration can be constructed. This allows the countdown timer for the scheduled upgrade to be dynamically set according to different upgrade packages and different environments in which the vehicle is located, which is more in line with actual application needs. At the same time, during the countdown, the vehicle will enter the scheduled upgrade state, which forces the vehicle to be under high voltage and prevents it from entering hibernation, thus avoiding upgrade failure caused by hibernation.

[0073] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 Step S10 includes steps S101 to S103: Step S101: Obtain the vehicle model and hardware configuration information.

[0074] It should be noted that the vehicle model can be an identifier representing the vehicle type, while the hardware configuration information can be information about the specific hardware configuration in the vehicle, such as the ECU model and the installation time.

[0075] In practical use, the vehicle model and hardware configuration information can be determined based on the vehicle identification code (such as VIN code). For example, the vehicle's manufacturing record and hardware replacement record can be found based on the vehicle identification code. The vehicle model can be determined based on the manufacturing record, and the hardware configuration information can be determined based on the hardware information in the manufacturing record and the hardware change information in the hardware replacement record.

[0076] Step S102: Determine the basic upgrade speed based on the hardware configuration information, and determine the duration correction coefficient based on the vehicle model and the hardware configuration information.

[0077] It should be noted that the base upgrade speed can be the maximum speed at which the vehicle can be upgraded without other influencing factors, and the time correction factor can be the ratio between the actual upgrade time and the estimated upgrade time. The estimated upgrade time is the upgrade time taken at a constant base upgrade speed.

[0078] In practical use, the basic upgrade speed of a vehicle can be estimated based on hardware configuration information. At the same time, historical upgrade records can be searched based on the vehicle model and hardware configuration information to determine the ratio between the actual upgrade speed and the estimated upgrade speed of other vehicles of the same model and hardware configuration, thereby determining the time correction coefficient.

[0079] Step S103: Construct the basic upgrade duration based on the upgrade package specifications, the basic upgrade speed, and the duration correction coefficient.

[0080] In practical use, the basic upgrade duration can be constructed based on the upgrade package specifications, the basic upgrade speed, and the duration correction factor.

[0081] For example: Assuming the upgrade package size is 100MB, the basic upgrade speed is 10MB / minute, and the duration correction factor is 2, then the basic upgrade time is (100 / 10). 2 = 20 minutes.

[0082] This embodiment provides a vehicle system upgrade method. Since the actual basic upgrade speed of the vehicle can be determined based on the vehicle model and hardware configuration information, as well as the duration correction coefficient reflecting the difference between the estimated and actual upgrade, the basic upgrade duration is generated by combining the basic upgrade speed, the duration correction coefficient and the upgrade package specifications, making the constructed basic upgrade duration more accurate and more in line with the actual situation.

[0083] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the vehicle system upgrade method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0084] This application also provides a vehicle system upgrade device, please refer to...

The upgrade module 40 is used to control the vehicle to perform a vehicle system upgrade when the timer reaches the upgrade prompt duration.
