[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The vehicle energy limiting method provided in the embodiment of the present application can be applied to the application environment shown in FIG. 1. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. When the vehicle meets the preset vehicle energy limiting conditions, the computer device obtains the battery power of the vehicle battery; if the battery power is less than the preset power threshold, the vehicle energy limiting mode is started, and the battery current of the vehicle battery is obtained; in the vehicle energy limiting mode, the power of the on-board electrical equipment is reduced; when the battery current is greater than the preset charging current threshold, the vehicle energy limiting mode is exited. Among them, the computer device can be either a terminal or a server. The terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0055] In an exemplary embodiment, as shown in FIG2 , a vehicle energy limiting method is provided, which is described by taking the method applied to the computer device (such as the vehicle-mounted terminal) in FIG1 as an example, and includes the following steps 201 to 204. Among them:

[0056] Step 201, when the vehicle meets the preset vehicle energy limit condition, the battery power of the vehicle battery is obtained.

[0057] Among them, the preset vehicle energy limiting condition can be that only the vehicle battery is in a discharging state, or the operating state is not started, the vehicle ignition state is ignited, and the battery current of the vehicle battery is less than a preset discharge current threshold.

[0058] Specifically, when the vehicle-mounted terminal detects that only the battery in the vehicle is in a discharging state, the battery power of the vehicle is obtained.

[0059] Step 202: If the battery power is less than a preset power threshold, the vehicle energy limiting mode is activated and the battery current of the vehicle battery is obtained.

[0060] Specifically, determine whether the battery charge of the vehicle battery is less than a preset charge threshold. If the battery charge is greater than the preset charge threshold, it proves that the vehicle can be ignited and started normally without entering the vehicle energy limitation mode. If the battery charge is less than the preset charge threshold, it proves that the vehicle may not be able to ignite and start normally, and the vehicle energy limitation mode needs to be activated to maintain the charge of the vehicle battery to avoid the vehicle running out of power and the problem of the vehicle being unable to start the next time it is used. At the same time, the battery current of the vehicle battery is obtained, so the vehicle energy limitation mode is activated and a reminder that "the vehicle has entered protective energy limitation mode" is output.

[0061] Step 203: In the vehicle energy limiting mode, the power of the vehicle-mounted electrical equipment is reduced.

[0062] Among them, the vehicle-mounted electrical equipment includes necessary electrical equipment and non-essential electrical equipment. The necessary electrical equipment may include the main and auxiliary instrument screens, etc., and the non-essential electrical equipment may include vehicle-mounted entertainment, air conditioning, etc.

[0063] Specifically, when the vehicle is in the vehicle energy-limiting mode, the embedded event manager (EEM system) in the vehicle terminal issues an energy-limiting instruction to reduce the power of the vehicle's electrical equipment, or maintain the power supply of necessary electrical equipment and interrupt the power supply of non-essential electrical equipment. For example, in the vehicle energy-limiting mode, the vehicle terminal will reduce the original air-conditioning wind speed to the lowest air-conditioning wind speed to reduce the power of the vehicle's electrical equipment.

[0064] Step 204 : when the battery current is greater than a preset charging current threshold, exit the vehicle energy limiting mode.

[0065] Among them, the charging current threshold can be zero, that is, if the battery current is greater than the preset charging current threshold, it proves that the battery power of the vehicle battery is in a charging state; if the battery current is less than the preset charging current threshold, it proves that the battery power of the vehicle battery is in a discharging state.

[0066] Specifically, determine whether the battery current is greater than the preset charging current threshold. If the battery current is less than the preset charging current threshold, it proves that the battery power of the vehicle battery may not be able to support the normal operation of the vehicle at this time. Therefore, it is still necessary to maintain the vehicle energy limitation mode; if the battery current is greater than the preset charging current threshold, it proves that the vehicle battery may be in a charging state. Therefore, the vehicle energy limitation mode can be exited.

[0067] The above-mentioned vehicle energy limiting method, device, computer equipment and storage medium obtain the battery power of the vehicle battery when the vehicle meets the preset vehicle energy limiting conditions; if the battery power is less than the preset power threshold, the vehicle energy limiting mode is started and the battery current of the vehicle battery is obtained; in the vehicle energy limiting mode, the power of the on-board electrical equipment is reduced; when the battery current is greater than the preset charging current threshold, the vehicle energy limiting mode is exited. In the present application, when the vehicle meets the preset vehicle energy limiting conditions, the vehicle energy limiting mode is determined according to the battery power, and when the battery current is greater than the charging current threshold, that is, the battery is in a charging state, the vehicle energy limiting mode is exited, which can avoid the continuous power loss of the battery without affecting the functional operation of the vehicle. At the same time, this embodiment can also intervene in the control in time and make the vehicle enter the protective energy limiting mode when the battery is over-discharged and there is a risk or trend of power loss, so as to avoid excessive discharge of the vehicle battery or power loss accidents, and further avoid the situation where the battery is over-discharged, resulting in accelerated aging of the battery or even serious power loss and inability to start the vehicle.

[0068] In some embodiments, if the battery power is less than a preset power threshold, the vehicle energy limitation mode is activated, including: if the battery power is less than a preset first-level power threshold and greater than a preset second-level power threshold, a low battery reminder is output; if the battery power is less than a preset second-level power threshold, the vehicle energy limitation mode is activated.

[0069] The preset power threshold includes a preset first power threshold and a preset second power threshold; the preset first power threshold is greater than the preset second power threshold. For example, the preset first power threshold may be 20%, and the preset second power threshold may be 15%.

[0070] Specifically, it is determined whether the battery power is less than the preset first-level power threshold. If the battery power is greater than the preset first-level power threshold, it proves that the battery power of the vehicle battery can support the functional operation of the vehicle and normal ignition and start-up, so there is no need to start the vehicle energy-limiting mode; if the battery power is less than the preset first-level power threshold, it proves that the vehicle battery may not be able to ensure the normal ignition and start-up of the vehicle while supporting the functional operation of the vehicle. Therefore, it is necessary to further determine whether the battery power is less than the preset second-level power threshold. If the battery power is not less than the preset second-level power threshold, it proves that the battery power of the vehicle battery is low at this time, and it is necessary to output a reminder of low battery power, and prompt the user to start the engine (the engine can supply power to the vehicle battery after starting) or power off (such as turning off the ignition). If the battery power is less than the preset second-level power threshold, it proves that the vehicle battery may not be able to support the normal ignition and start-up of the vehicle at this time, and it is necessary to start the vehicle energy-limiting mode, while interrupting the power supply of some on-board electrical equipment, and / or reducing the power of the on-board electrical equipment to maintain the battery power in the vehicle battery.

[0071] For example, assuming that the preset first-level power threshold can be 20%, the preset second-level power threshold can be 15%, and the vehicle-mounted terminal detects that the vehicle battery is in a discharge state, and the vehicle is in an ignition state, and the engine is not started. At this time, the battery power of the vehicle battery is obtained. If the battery power is 70%, that is, it has not reached the preset first-level power threshold, then the continuous monitoring state can be maintained; if the battery power is 18%, that is, it has reached the preset first-level power threshold, but has not reached the preset second-level power threshold, then the user is prompted that the battery power is low, please start the engine or turn off the power; if the battery power is 12%, that is, it has reached the preset second-level power threshold, then the user is warned that the battery power is low, and the power supply of some vehicle-mounted electrical equipment is interrupted.

[0072] This embodiment can effectively maintain the battery power of the vehicle battery.

[0073] In some embodiments, the method further includes: obtaining the operating state of the vehicle engine and the vehicle ignition state; when the operating state is not started and the vehicle ignition state is ignited, determining that the vehicle meets the preset vehicle energy limitation condition.

[0074] The running state includes started and not started, that is, the vehicle engine is in the started state or not started state. The vehicle engine will supply power to the battery when it is started. The vehicle ignition state includes ignition ON (IGON) and not ignition (IGOFF).

[0075] Specifically, the operating status of the vehicle engine and the vehicle ignition status are obtained. When it is detected that the operating status of the vehicle engine is not started and the vehicle ignition status is ignited, it proves that the vehicle battery is in a discharged state. Therefore, it is determined that the vehicle meets the preset vehicle energy limit conditions.

[0076] Preferably, this embodiment can also obtain the operating status of the vehicle engine, the vehicle ignition status and the battery current of the vehicle battery; when the operating status is not started, the vehicle ignition status is ignited, and the battery current of the vehicle battery is less than a preset discharge current threshold, it is determined that the vehicle meets the preset vehicle energy limitation conditions.

[0077] Specifically, when the running state is not started, the vehicle ignition state is ignited, and the battery current of the vehicle battery is less than the preset discharge current threshold, it proves that at this time the vehicle is only powered by the battery to provide power to the various electrical devices of the vehicle, and there is no external power supply to replenish the vehicle battery. Therefore, it is determined that the vehicle meets the preset vehicle energy limit conditions.

[0078] This embodiment determines whether the vehicle meets the preset vehicle energy limitation condition through the running state of the vehicle engine, the ignition state of the vehicle and the battery current of the vehicle battery, thereby improving the accuracy of determining the vehicle energy limitation condition.

[0079] In some embodiments, the method further includes: obtaining a vehicle ignition status when a battery current of a vehicle battery is less than a preset charging current threshold; and determining whether to turn off a vehicle energy limiting mode according to the vehicle ignition status.

[0080] The charging current threshold may be a standard for determining whether the vehicle battery is in a charging state. Optionally, the charging current threshold may be zero.

[0081] Specifically, when the battery current of the vehicle battery is greater than the preset charging current threshold, it proves that the vehicle battery is in a charging state at this time, and therefore, the vehicle energy limitation mode can be exited; when the battery current of the battery is less than the preset charging current threshold, it is necessary to further determine whether the user has shut down the vehicle and powered off. If the vehicle is still in the ignition state, the vehicle energy limitation mode must be maintained to protect the vehicle battery from over-discharge; if the vehicle is in the unignition state, it proves that the vehicle has been shut down and powered off, and the vehicle battery does not need to be consumed anymore, and therefore, the vehicle energy limitation mode can be ended.

[0082] This embodiment can determine whether to turn off the vehicle energy limiting mode according to the battery current, thereby effectively avoiding excessive discharge of the vehicle battery or a power shortage accident.

[0083] In one embodiment, this embodiment provides an optional method for limiting vehicle energy, and takes the method applied to a server as an example for explanation. As shown in FIG3 , the method includes the following steps:

[0084] Step 301, obtaining the running state of the vehicle engine, the vehicle ignition state and the battery current of the vehicle battery.

[0085] Step 302, when the running state is not started, the vehicle ignition state is ignited, and the battery current of the vehicle battery is less than the preset discharge current threshold, determine that the vehicle meets the preset vehicle energy limit condition, and obtain the battery power of the vehicle battery.

[0086] Step 303, determine whether the battery power is less than a preset first-level power threshold, if not, execute step 302, and if so, execute step 304.

[0087] Step 304, determine whether the battery power is less than the preset secondary power threshold, if not, execute step 305, if yes, execute step 306.

[0088] Step 305: output a reminder of low battery power.

[0089] Step 306: Start the vehicle energy limiting mode to reduce the power of the vehicle's electrical equipment.

[0090] Step 307 , determining whether the battery current is greater than a preset charging current threshold, if so, executing step 308 , if not, executing step 309 .

[0091] Step 308, exit the vehicle energy limited mode.

[0092] Step 309 , determining whether the vehicle ignition status is ignited, if so, executing step 307 , if not, executing step 310 .

[0093] Step 310, end.

[0094] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
