Description

Technical Field

[0001] This invention relates to the field of vehicle network terminal control technology, specifically to a TBOX wake-up method, device, equipment, and medium based on battery voltage protection. Background Technology

[0002] As the core carrier of vehicle networking functions, the in-vehicle TBOX needs to respond to wake-up requests such as remote vehicle control, data reporting, emergency alarms, and high-voltage services. When a vehicle is parked for a long time, the battery does not receive charging and its voltage continues to decrease due to self-discharge characteristics. Unnecessary wake-ups at this time will exacerbate power consumption and may lead to deep discharge, affecting the reliability of vehicle starting.

[0003] Therefore, there is an urgent need for a TBOX wake-up method, device, equipment, and medium based on battery voltage protection to address the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a TBOX wake-up method, apparatus, device, and medium based on battery voltage protection, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the first aspect of this invention proposes a TBOX wake-up method based on battery voltage protection, comprising: Collect battery voltage data to determine whether the battery has been sitting for a long time; When the battery is in a long-term static state, the average battery voltage and the battery voltage decay rate are calculated based on the battery voltage data. The high-voltage and low-voltage thresholds of the battery are adaptively adjusted based on the battery voltage decay rate. The battery is woken up in stages according to wake-up commands based on the high voltage threshold and low voltage threshold of the battery.

[0006] Furthermore, the specific method for determining whether a battery has been in a long-term static state is as follows: When the battery voltage fluctuation is less than or equal to the battery voltage fluctuation threshold, the TBOX built-in timer starts timing. When the duration of the TBOX built-in timer is greater than or equal to the preset duration, the battery is determined to be in a long-term idle state.

[0007] Furthermore, specific methods for calculating the average battery voltage and the battery voltage decay rate based on battery voltage data include: TBOX continuously collects three sets of battery voltage data through a battery voltage sensor and calculates the average value of the three sets of battery voltage data as the average battery voltage. Calculate the battery voltage decay rate, where the battery voltage decay rate is the absolute value of the difference between the battery's average voltage and the battery's average voltage at the same time the previous day.

[0008] Furthermore, specific methods for adaptively adjusting the high-voltage and low-voltage thresholds of a battery based on its voltage decay rate include: If the battery voltage decay rate is greater than the first threshold for three consecutive days, the first voltage value will be increased for both the low voltage threshold and the high voltage threshold. If the battery voltage decay rate is less than the first threshold for 7 consecutive days, the low voltage threshold will be lowered to the second voltage value.

[0009] Furthermore, the specific method for graded wake-up of the battery based on wake-up commands according to the battery's high-voltage and low-voltage thresholds includes: If the average battery voltage is greater than or equal to the high voltage threshold, the battery load voltage is detected. If the battery load voltage is greater than or equal to the third voltage value, emergency wake-up command, low voltage service wake-up command, and high voltage service wake-up command are allowed to wake up the battery. If the battery load voltage is less than the third voltage value, emergency wake-up command and low voltage service wake-up command are allowed to wake up the battery, and the first warning is pushed. If the low-voltage threshold is less than or equal to the average battery voltage being less than the high-voltage threshold, emergency wake-up commands and low-voltage service wake-up commands are allowed to wake up the battery and push a second warning. If the average battery voltage is less than the low voltage threshold, only the emergency wake-up command is allowed to wake up the battery and push the third warning.

[0010] Furthermore, after grading the battery wake-up according to the wake-up command based on the battery's high-voltage threshold and low-voltage threshold, the process also includes: After the battery is woken up according to the emergency wake-up command, if the average voltage of the battery is still less than the low voltage threshold, the TBOX will only retain its core functions; the power battery will replenish the battery, and during the replenishment period, the low voltage service wake-up and high voltage service wake-up will be suspended and the battery will enter deep sleep. After the battery is woken up according to the high-voltage service wake-up command, the high-voltage service is executed. After the high-voltage service is completed, the battery voltage is monitored. If the battery voltage drops to a value greater than or equal to the fourth voltage value, the high-voltage threshold will be temporarily increased to the fifth voltage value when the next similar command is triggered. Once the battery is woken up according to the low-voltage service wake-up command, it executes the low-voltage service and then immediately goes into hibernation.

[0011] A second aspect of the present invention provides a TBOX wake-up device based on battery voltage protection, comprising: a judgment module, a monitoring module, an adjustment module, and a wake-up module; The judgment module is used to collect battery voltage data and determine whether the battery is in a long-term static state. The monitoring module is used to calculate the average battery voltage, battery voltage, and battery voltage decay rate based on battery voltage data when the battery is in a long-term static state. The adjustment module is used to adaptively adjust the high-voltage threshold and low-voltage threshold of the battery based on the battery voltage decay rate; The wake-up module is used to perform graded wake-up of the battery based on wake-up commands based on the battery's high-voltage threshold and low-voltage threshold.

[0012] Furthermore, it also includes: The status processing module is used to ensure that when the battery is woken up according to the emergency wake-up command, if the average voltage of the battery is still less than the low voltage threshold, the TBOX retains only the core functions, the power battery replenishes the battery, and during the replenishment period, the low voltage service wake-up and high voltage service wake-up are suspended and the battery enters deep sleep. After the battery is woken up according to the high-voltage service wake-up command, the high-voltage service is executed. After the high-voltage service is completed, the battery voltage is monitored. If the battery voltage drops to a value greater than or equal to the fourth voltage value, the high-voltage threshold will be temporarily increased to the fifth voltage value when the next similar command is triggered. Once the battery is woken up according to the low-voltage service wake-up command, it executes the low-voltage service and then immediately goes into hibernation.

[0013] A third aspect of the present invention provides an electronic device comprising: a memory, a processor, and a computer program, the computer program being stored in the memory and configured to be executed by the processor to implement a TBOX wake-up method based on battery voltage protection.

[0014] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements a TBOX wake-up method based on battery voltage protection.

[0015] The beneficial effects of the technical solutions provided by the embodiments of the present invention include: 1. Precise protection for high-voltage services: Added load capacity detection and dedicated threshold to prevent sudden drop in battery voltage caused by starting high-voltage services under low power conditions, reducing the risk of battery depletion; 2.

Compatibility and low cost: The static state is determined solely by battery voltage data, without relying on additional signals such as the engine, making it compatible with both gasoline and new energy vehicles; it is implemented through software optimization, requiring no hardware modifications and reducing implementation costs. Attached Figure Description

[0016] Figure 1 This is a flowchart illustrating an embodiment of a TBOX wake-up method based on battery voltage protection; Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 The first aspect of this invention proposes a TBOX wake-up method based on battery voltage protection, such as... Figure 1 As shown, the method includes: Collect battery voltage data to determine whether the battery has been sitting for a long time; Furthermore, the specific method for determining whether a battery has been in a long-term static state is as follows: When the battery voltage fluctuation is less than or equal to the battery voltage fluctuation threshold, the TBOX built-in timer starts timing. When the duration of the TBOX built-in timer is greater than or equal to the preset duration, the battery is determined to be in a long-term idle state.

[0019] Specifically, when no wake-up command is received and the battery voltage fluctuation is ≤ ±0.03V / 24 hours, the TBOX built-in timer starts timing; when the TBOX built-in timer timing duration T ≥ 7 days, the battery is determined to be in a long-term static state; if the battery voltage fluctuation is detected to be > ±0.03V / 24 hours, the timing T is reset to 0, and the long-term static state is exited.

[0020] When the battery is in a long-term static state, the average battery voltage and the battery voltage decay rate are calculated based on the battery voltage data. Furthermore, specific methods for calculating the average battery voltage and the battery voltage decay rate based on battery voltage data include: TBOX continuously collects three sets of battery voltage data through a battery voltage sensor and calculates the average value of the three sets of battery voltage data as the average battery voltage. Calculate the battery voltage decay rate, where the battery voltage decay rate is the absolute value of the difference between the battery's average voltage and the battery's average voltage at the same time the previous day.

[0021] Specifically, TBOX continuously acquires three sets of battery voltage data through a battery voltage sensor. After removing instantaneous fluctuation anomalies with a deviation exceeding 0.05V, the average value is taken as the average battery voltage V. The daily battery voltage decay rate ΔV is calculated, where the battery voltage decay rate is the absolute value of the difference between the average battery voltage and the average battery voltage at the same time on the previous day.

[0022] The high-voltage and low-voltage thresholds of the battery are adaptively adjusted based on the battery voltage decay rate. Furthermore, specific methods for adaptively adjusting the high-voltage and low-voltage thresholds of a battery based on its voltage decay rate include: If the battery voltage decay rate is greater than the first threshold for three consecutive days, the first voltage value will be increased for both the low voltage threshold and the high voltage threshold. If the battery voltage decay rate is less than the first threshold for 7 consecutive days, the low voltage threshold will be lowered to the second voltage value.

[0023] Specifically, the low-voltage threshold is initially set to 12.5V to meet the basic protection requirements after the battery has naturally discharged, and can be calibrated according to the vehicle model; the high-voltage threshold is set to 12.7V to ensure the instantaneous high current requirements when high-voltage services are started, such as the starting current of the air conditioning compressor of 50-100A, and to avoid a sudden drop in battery voltage, and can be calibrated according to the vehicle model. If the battery voltage decay rate ΔV is monitored to be greater than 0.02V / day for 3 consecutive days, the low voltage threshold and the high voltage threshold will be automatically increased by 0.05V and locked to prevent further decrease, thereby enhancing the protection against power loss of aging batteries. If the battery voltage decay rate ΔV < 0.01V / day is monitored for 7 consecutive days, the battery is in an abnormally healthy state. The low voltage threshold can be lowered by 0.02V to avoid over-protection.

[0024] The battery is woken up in stages according to wake-up commands based on the high voltage threshold and low voltage threshold of the battery.

[0025] Specifically, wake-up commands include: emergency wake-up commands, high-voltage service wake-up commands, and low-voltage service wake-up commands. Emergency wake-up commands include safety-related commands such as collision alarms and eCall calls; high-voltage service wake-up commands include commands such as air conditioning start, seat heating, and ventilation; low-voltage service wake-up commands include commands such as remote status query and routine data reporting.

[0026] Battery voltage data, high voltage threshold and low voltage threshold adjustment records, and wake-up logs under long-term static conditions are all stored using AES-256 encryption and are retained for ≥90 days, supporting traceability and fault analysis.

[0027] Furthermore, the specific method for graded wake-up of the battery based on wake-up commands according to the battery's high-voltage and low-voltage thresholds includes: If the average battery voltage is greater than or equal to the high voltage threshold, the battery load voltage is detected. If the battery load voltage is greater than or equal to the third voltage value, emergency wake-up command, low voltage service wake-up command, and high voltage service wake-up command are allowed to wake up the battery. If the battery load voltage is less than the third voltage value, emergency wake-up command and low voltage service wake-up command are allowed to wake up the battery, and the first warning is pushed. If the low-voltage threshold is less than or equal to the average battery voltage being less than the high-voltage threshold, emergency wake-up commands and low-voltage service wake-up commands are allowed to wake up the battery and push a second warning. If the average battery voltage is less than the low voltage threshold, only the emergency wake-up command is allowed to wake up the battery and push the third warning.

[0028] Specifically, if the average battery voltage is ≥ the high voltage threshold of 12.7V, the high voltage device is briefly activated within 100ms to detect the battery's load voltage; if the load battery voltage is ≥ 11.8V, emergency wake-up commands, low voltage service wake-up commands, and high voltage service wake-up commands are allowed to wake up the battery; if the load battery voltage is < 11.8V, emergency wake-up commands and low voltage service wake-up commands are allowed to wake up the battery and push an alert: "The power seems sufficient but the load capacity is insufficient, charging is recommended."

[0029] If the low-voltage threshold of 12.5V ≤ the average battery voltage V < the high-voltage threshold of 12.7V: Allow emergency wake-up commands and low-voltage service wake-up commands, reject high-voltage service wake-up commands, and push a warning: "Battery voltage is insufficient, high-voltage functions such as air conditioning / seats cannot be started temporarily. It is recommended to charge the battery before operation."

[0030] If the average battery voltage V < low voltage threshold 12.5V: only emergency wake-up is allowed, other types of wake-up are rejected, and a warning is pushed: "Battery voltage is too low, please charge in time".

[0031] Furthermore, after grading the battery wake-up according to the wake-up command based on the battery's high-voltage threshold and low-voltage threshold, the process also includes: After the battery is woken up according to the emergency wake-up command, if the average voltage of the battery is still less than the low voltage threshold, the TBOX will only retain its core functions; the power battery will replenish the battery, and during the replenishment period, the low voltage service wake-up and high voltage service wake-up will be suspended and the battery will enter deep sleep. After the battery is woken up according to the high-voltage service wake-up command, the high-voltage service is executed. After the high-voltage service is completed, the battery voltage is monitored. If the battery voltage drops to a value greater than or equal to the fourth voltage value, the high-voltage threshold will be temporarily increased to the fifth voltage value when the next similar command is triggered. Once the battery is woken up according to the low-voltage service wake-up command, it executes the low-voltage service and then immediately goes into hibernation.

[0032] Specifically, after the battery is woken up according to the emergency wake-up command, if the average battery voltage is still less than the low-voltage threshold, the TBOX retains only its core functions, including data acquisition and storage, remote query and control, local control, roadside assistance, remote diagnostics, and anomaly alerts. Non-core functions of the TBOX are turned off to reduce ineffective energy consumption. These non-core functions include infotainment and ecosystem services, software upgrades, etc. The power battery replenishes the battery, suspending low-voltage and high-voltage wake-up services and entering deep sleep during the replenishment process. If there is no subsequent emergency wake-up command within 30 seconds, it enters deep sleep.

[0033] After the battery is woken up according to the high-voltage service wake-up command, the high-voltage service is executed. After the high-voltage service is executed, the battery voltage is monitored for 3 minutes. If the battery voltage drops by ≥0.3V, it is recorded as "affected by high power consumption service". The high-voltage threshold is temporarily increased by 0.1V when the next similar command is triggered. After the battery is woken up according to the low-voltage service wake-up command, it will execute the low-voltage service limited wake-up time of ≤30 seconds and then immediately go into hibernation.

[0034] Example 2 A second aspect of the present invention provides a TBOX wake-up device based on battery voltage protection, comprising: a judgment module, a monitoring module, an adjustment module, and a wake-up module; The judgment module is used to collect battery voltage data and determine whether the battery is in a long-term static state. The monitoring module is used to calculate the average battery voltage, battery voltage, and battery voltage decay rate based on battery voltage data when the battery is in a long-term static state. The adjustment module is used to adaptively adjust the high-voltage threshold and low-voltage threshold of the battery based on the battery voltage decay rate; The wake-up module is used to perform graded wake-up of the battery based on wake-up commands based on the battery's high-voltage threshold and low-voltage threshold.

[0035] Furthermore, it also includes: The status processing module is used to ensure that if the average voltage of the battery is still less than the low voltage threshold after the battery is woken up according to the emergency wake-up command, the TBOX retains only the core functions; the power battery replenishes the battery, and during the replenishment period, the low voltage service wake-up and high voltage service wake-up are suspended and the battery enters deep sleep. After the battery is woken up according to the high-voltage service wake-up command, the high-voltage service is executed. After the high-voltage service is completed, the battery voltage is monitored. If the battery voltage drops to a value greater than or equal to the fourth voltage value, the high-voltage threshold will be temporarily increased to the fifth voltage value when the next similar command is triggered. Once the battery is woken up according to the low-voltage service wake-up command, it executes the low-voltage service and then immediately goes into hibernation.
