[0002] With the rapid development of intelligent vehicles, the number of onboard electronic devices has also increased, and with it, the number of vehicle battery failures has also increased, leading to the problem of being unable to start the vehicle. When faced with a battery failure, traditional technology assumes that when the battery charge falls below a certain threshold, it is judged that the vehicle is about to run out of power, that is, it is judged to be at risk of battery failure. However, due to the increasing number of scenarios in which vehicles are running out of power, relying solely on the battery charge to determine whether the vehicle is at risk of running out of power is obviously not comprehensive enough. Therefore, traditional technology has the problem of not being accurate and comprehensive in judging whether the vehicle is at risk of running out of power, and is therefore unable to effectively formulate an accurate and comprehensive anti-battery strategy for the vehicle.

[0018] See also Figure 1 , Figure 1 This is a system architecture diagram of the vehicle battery loss prevention method provided in the embodiment of the present application, which includes a terminal 140, an Internet 130, a gateway 120, a server 110, etc.

[0019] Terminal 140 can take various forms, including desktop computers, laptops, PDAs (personal digital assistants), mobile phones, in-vehicle terminals, and dedicated terminals. Furthermore, it can be a single device or a combination of multiple devices. For example, multiple desktop computers connected via a local area network, sharing a common display and working collaboratively, collectively constitute terminal 140. Terminal 140 can communicate with Internet 130 via wired or wireless means to exchange data.

[0020] Server 110 is a computer system that provides certain services to terminal 140. Compared to ordinary terminal 140, server 110 has higher requirements in terms of stability, security, and performance. Server 110 can be a single high-performance computer in a network platform, a cluster of multiple high-performance computers, a portion of a single high-performance computer (e.g., a virtual machine), or a combination of portions of multiple high-performance computers (e.g., virtual machines). Server 110 can also communicate with the Internet 130 via wired or wireless means to exchange data.

[0021] Gateway 120, also known as a gateway or protocol converter, implements network interconnection at the transport layer and is a computer system or device that performs a conversion function. It acts as a translator between two systems using different communication protocols, data formats, languages, or even completely different architectures. Gateways can also provide filtering and security functions. Messages sent from terminal 140 to server 110 are sent through gateway 120 to the corresponding server 110. Messages sent from server 110 to terminal 140 are also sent through gateway 120 to the corresponding terminal 140.

[0022] The following is a detailed introduction to the specific implementation of the embodiment of this application: See also Figure 2 , Figure 2 It is a flow chart of a method for preventing a vehicle from running out of power provided in an embodiment of the present application. The method for preventing a vehicle from running out of power can be implemented by the server 110 and / or the terminal 140. Figure 2 The vehicle power loss prevention method shown includes: Step 210: Determine vehicle state parameters of the vehicle and power state parameters of the battery of the vehicle; Step 220: Determine a low-battery condition of the battery based on the vehicle state parameter and the power supply state parameter; Step 230: Determine a battery-low prevention strategy for the vehicle based on the battery-low operating condition, and perform a battery-low prevention operation corresponding to the battery-low prevention strategy.

[0023] The following is a detailed explanation of steps 210-230: In step 210, the vehicle status parameters may include the vehicle's load operating status, door status, and hood status. The vehicle's load operating status is used to represent the discharge parameters of the battery to the vehicle's load. The higher the battery's discharge parameter (e.g., discharge current) to the vehicle, the higher the load power consumption represented by the load operating status. Power supply status parameters may include battery voltage, battery current, battery charge, and battery temperature.

[0024] In step 220, the battery low condition can be determined based on the vehicle state parameters and the power state parameters. First, the power state parameters are used to determine whether the battery has a low condition risk. A low condition risk refers to a situation where the battery is about to be low.

[0025] In some embodiments, if any of the following four situations occurs, it is considered that the battery is at risk of power failure: First, the battery voltage is less than the preset voltage threshold; Second, the battery current (i.e., the instantaneous current used to start the vehicle) is less than a preset current threshold; Third, the battery power is less than the preset power threshold; Fourth, the battery temperature is greater than a preset temperature threshold.

[0026] The preset voltage threshold can be set according to actual needs. Here, the preset voltage threshold can be specifically 12.5V. The preset current threshold can be set according to actual needs. Here, the preset current threshold can be set to 150A. The preset power threshold can be set according to actual needs. Here, the preset power threshold can be set to 55%. The preset temperature threshold can be set according to actual needs. Here, the preset temperature threshold can be specifically 50 degrees Celsius.

[0027] In some embodiments, when the battery is at risk of being low on power, the low-power condition of the battery is further determined based on the vehicle state parameters. Specifically, determining the low-power condition of the battery based on the vehicle state parameters includes: determining a discharge parameter of the battery to the load of the vehicle based on the load operating state of the vehicle; If the discharge parameter is greater than a preset discharge parameter threshold, determining that the battery power-deficient condition is a load power-deficient condition; If the door state is open, determining that the battery low-power condition is a door low-power condition; If the bonnet state is open, it is determined that the battery low-power condition is the bonnet low-power condition.

[0028] Specifically, through the load operating status of the vehicle, it can be determined which loads of the vehicle the battery has discharged and what the specific discharge parameters are. Then, when the discharge parameter is too large, that is, when the discharge parameter is greater than the preset discharge parameter threshold (for example, the discharge current is greater than the preset discharge current threshold, and the preset discharge current threshold can be set to 5A for example), the battery's low-power condition is determined to be a load low-power condition. The load low-power condition is used to characterize the risk of low-power caused by the high power consumption of the load.

[0029] When the car door is in the open state, it is also easy to cause the risk of power loss. Therefore, the power loss condition can be determined as the car door power loss condition. The load power loss condition is used to characterize the power loss risk caused by the car door being opened for a long time or frequently opened and closed.

[0030] When the bonnet is in the open state, it is also easy to cause the risk of power failure. Therefore, the power failure condition can be determined as the bonnet power failure condition. The bonnet power failure condition is used to characterize the power failure risk caused by the bonnet being opened for a long time or frequently opened and closed.

[0031] In step 230 , different power failure prevention strategies may be determined for different power failure conditions, so as to perform power failure prevention operations in a targeted manner.

[0032] In some embodiments, determining a battery-loss prevention strategy for the vehicle based on the battery-loss condition includes: When the power failure condition is the load power failure condition, determining the power failure prevention strategy to be the first strategy; When the power-loss condition is the vehicle door power-loss condition or the engine hood power-loss condition, the power-loss prevention strategy is determined to be the second strategy.

[0033] Specifically, when the power-loss condition is the load power-loss condition, that is, when the power-loss risk is caused by the high power consumption of the load, the power-loss prevention strategy is determined to be the first strategy. Then the power-loss prevention operation corresponding to the first strategy is to control the dashboard of the vehicle to display a prompt message to start the vehicle, and reduce the operating power of the vehicle's load, or limit the vehicle's load operation to reduce the discharge parameters of the battery to the vehicle's load. If the vehicle is not started within a first preset time (the first preset time can be exemplarily 1 minute), the vehicle is controlled to power off to prevent the power-loss risk from further increasing, thereby preventing the occurrence of the power-loss problem.

[0034] When the low-battery condition is a door low-battery condition or a hood low-battery condition, the low-battery prevention strategy is determined to be the second strategy. Under the second strategy, the corresponding low-battery prevention operation is to control the vehicle's instrument panel to display a prompt message to start the vehicle, indicating that there is a current low-battery risk and the vehicle needs to be started, using high voltage to charge (or recharge) the low-voltage battery. If the vehicle is not started within a second preset time (the second preset time is exemplarily set to 90 seconds), the vehicle is forced to power down to prevent the low-battery risk from further increasing. If the vehicle is started within the second preset time, the deep recharge strategy is triggered, which means that the low-voltage battery is recharged with the high-voltage battery. It should be noted that the low-battery risk only exists in the low-voltage battery, and the batteries described in this application are all low-voltage batteries.

[0035] Reference Figure 3 As shown, the following combination Figure 3 The specific application scenarios of this application are described in detail: First, the vehicle is started, that is, the vehicle is unlocked, but not in the high-voltage state. At this time, if the charging system fails, that is, the output current of the charging system (all batteries) is 0, then the vehicle fault alarm will be prompted on the vehicle display screen. At the same time, the fault alarm can also be given to the driver through voice, prompting the driver to repair the vehicle.

[0036] When the vehicle's charging system is fault-free, it enters the IG ON state. IG ON indicates that the vehicle has not started and the vehicle's starting power supply is not connected. For example, in a camping scenario, if the user or driver opens the vehicle door or hood for a long time, or frequently opens the door or hood, it is considered that there is a risk of low battery. In this case, the vehicle power-off alarm prompt will be displayed on the vehicle's display screen, accompanied by two long warning sounds to remind the user. At this time, the user can choose to start the vehicle or choose to power off the vehicle. After starting the vehicle, the vehicle generates electricity to replenish the battery. After the vehicle is powered off, the vehicle is powered on, that is, the starting power supply is connected but the vehicle is not started.

[0037] Based on this, if the vehicle's doors or hood are frequently opened and closed, a recharge operation is triggered. This recharge operation can specifically involve powering on the vehicle, essentially connecting the starting power source. After connecting the starting power source, the vehicle can be started to recharge. If power is not applied at this time, an IG OFF warning prompt will be issued. IG OFF indicates that the vehicle has not been started and the starting power source is not on. For example, if the user parks to move items, waits for someone, or performs electrical maintenance, if the vehicle is continuously operated in the IG OFF state and frequently wakes up, and the battery is detected to be at risk of low charge, the user will first be prompted on the display to avoid frequent vehicle operation and to start the vehicle if necessary. This text and audio prompt prevents the user from being out of the cab and unable to promptly address the problem. If the user starts the vehicle at this time, the system enters deep recharge mode, which uses the high-voltage battery to recharge the low-voltage battery. The high-voltage battery powers the entire vehicle while also recharging the low-voltage battery, ensuring that the low-voltage battery's charge is restored to normal to ensure the vehicle's starting ability.

[0038] To summarize, this application comprehensively considers multiple factors, including vehicle status parameters (the vehicle's load operating status, door status, and hood status) and power status parameters (battery voltage, current, power, and temperature) to accurately determine whether the battery is at risk of low power. At the same time, it formulates corresponding strategies to prevent low power and performs corresponding operations to prevent low power, which can greatly prevent the risk of low power from further aggravating, and at the same time, replenish the battery in a timely manner to solve the problems caused by the risk of low power.
