[0002] With the rapid development of vehicle intelligence, the types and number of electronic components in vehicles are also increasing, leading to a corresponding increase in the vehicle's quiescent current. Quiescent current refers to the current consumed when the vehicle is in sleep mode. In sleep mode, the increase in quiescent current leads to a greater static power consumption of the battery, and the accumulation of static power consumption increases the risk of the vehicle running out of power. Therefore, it is necessary to control the vehicle's quiescent current. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0034] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] Figure 1 This is a schematic diagram of an implementation environment provided in an embodiment of this application. For example... Figure 1 As shown, the implementation environment may include a vehicle 101 and a vehicle control system 102. The vehicle control system 102 is used to control the vehicle 101 to perform corresponding operations. The vehicle control system 102 may be located in the vehicle 101, for example, the vehicle control system 102 is an in-vehicle terminal; the vehicle control system 102 may also be located outside the vehicle 101, for example, the vehicle control system 102 is a cloud control system.

[0036] The vehicle control system 102 can be a single server, or it can be a server cluster consisting of multiple servers that perform different functions, or it can be a cloud computing center.

[0037] Vehicle 101 may have a battery module, which may include a battery that supplies power to the vehicle's electronic components. The battery module may also include a current sensor or a charge sensor to monitor the current flowing through the vehicle's electronic components or the charge level of the vehicle's battery. During vehicle parking, vehicle control system 102 may generate control signals based on the parking duration control domain controller of vehicle 101. These control signals may cut off power to some electronic components to reduce the vehicle's quiescent current. For example, vehicle control system 102 may generate a first control signal or a second control signal, which may control the cutting off of power to different electronic components.

[0038] The vehicle 101 may also have wireless communication capabilities. The vehicle 101 may be equipped with a communication module that supports wireless communication technology or wired communication technology. The vehicle 101 interacts with the vehicle control system 102 through the communication module.

[0039] Based on the above Figure 1 As shown in the implementation environment, this application provides a method for controlling the static current of a vehicle. Figure 2 As shown, this method can be derived from... Figure 1The method can be executed by vehicle 101, or it can be executed interactively by vehicle 101 and vehicle control system 102. The method may include steps 201 to 203.

[0040] In step 201, the parking duration information of the vehicle in sleep mode is obtained, including the actual parking duration.

[0041] In an exemplary embodiment of this application, the vehicle's sleep mode is characterized by the vehicle being armed while its network is in sleep mode. For example, after the vehicle stops and the engine is turned off, if the distance between the vehicle key and the vehicle is detected to be greater than or equal to a distance threshold, it indicates that the owner has left the vehicle, and the vehicle can enter armed mode, i.e., anti-theft mode. Then, the vehicle's network can enter sleep mode, causing the vehicle's electronic components to enter a low-power state, reducing the vehicle's power consumption.

[0042] Vehicle parking information can include the actual parking duration, which is the length of time from when the vehicle entered armed status to the current time. For example, after the vehicle is armed, the vehicle controller starts timing to obtain the actual parking duration.

[0043] The vehicle's battery can continue to power the vehicle's electronic components even after the vehicle is armed, meeting the need for some electronic components to continue operating while the vehicle is armed. For example, continuously operating electronic components may include, but are not limited to, those maintaining vehicle communication functions or those detecting vehicle status (e.g., door status, in-vehicle security, etc.). It should be noted that the electronic components that continue to operate after the vehicle is armed are illustrative in this application, and the configuration can be tailored to the actual vehicle conditions and the owner's needs; this application does not impose any limitations on this.

[0044] Optionally, after the vehicle is armed, the battery sensor can monitor at least one of the current flowing through the battery or the battery voltage, and send the monitored battery current or battery voltage to the vehicle controller in the form of a LIN (Local Interconnect Network) bus protocol signal, so that the vehicle controller can control the battery's operating status in real time.

[0045] In an exemplary embodiment of this application, the vehicle parking duration information may further include the vehicle's estimated parking duration, which may be determined based on at least one of historical parking duration or user-set duration.

[0046] In one embodiment of this application, the historical parking duration at a vehicle's parking location is obtained by analyzing the vehicle's historical data. This historical data may include the vehicle's parking location, the start and end times of the vehicle being armed, as recorded by the vehicle control system, thereby calculating the historical parking duration at the parking location. By analyzing the historical parking duration at a vehicle's parking location, the owner's parking habits can be identified. Based on the vehicle's parking location and historical duration, the estimated parking duration can be determined. For example, in historical data, on a weekday, the vehicle is parked in the company parking lot for approximately 8 hours. If the vehicle is currently parked in the company parking lot on a weekday, the estimated parking duration can be calculated as 8 hours.

[0047] In another embodiment of this application, after the vehicle stops and the engine is turned off, the owner can set the estimated parking duration based on personalized needs or travel plans via an in-vehicle display, mobile application, or other device communicating with the vehicle. Alternatively, after the vehicle is armed, the estimated parking duration can be set at any time via a mobile application or other device communicating with the vehicle.

[0048] In step 202, if the actual parking time is less than the first time threshold, a first control signal is generated. The first control signal is used to cut off the power supply to the first electronic component in the vehicle's electronic components. The vehicle's electronic components are used to generate static current. The first electronic component is different from the basic components, which are used to maintain the vehicle's wake-up function.

[0049] In an exemplary embodiment of this application, the first duration threshold can be a duration threshold automatically determined based on vehicle parameters and environmental parameters. The process of determining the first duration threshold based on vehicle parameters and environmental parameters may include steps A1 to A3.

[0050] In step A1, vehicle parameters and environmental parameters are obtained. The vehicle parameters include at least one of the following: total battery capacity, remaining battery capacity, or number of charge / discharge cycles of the battery. The environmental parameters include ambient temperature.

[0051] For example, vehicles are equipped with various types of sensors that can collect relevant vehicle data. For instance, the total battery capacity can be obtained from the vehicle's factory parameters; the remaining battery capacity or state of charge (SOC) can be obtained through battery sensors in the Battery Management System (BMS). SOC represents the percentage of the battery's total capacity remaining, where the remaining capacity is the product of the SOC and the total battery capacity; the number of charge / discharge cycles can be obtained using BMS logs. Ambient temperature can be obtained through temperature sensors installed on the vehicle.

[0052] In step A2, a first battery threshold is determined based on vehicle parameters and environmental parameters. The first battery threshold is a threshold that ensures the vehicle's wake-up function.

[0053] While the vehicle is armed, some of its electronic components are active, generating static current that consumes the vehicle's battery. The first battery threshold may differ depending on at least one of the vehicle's parameters or environmental parameters. This first battery threshold serves as the minimum battery level required to maintain the vehicle's wake-up function.

[0054] For example, the number of times a vehicle is charged and discharged can be used to assess the health of the battery. When a vehicle is charged and discharged many times, the battery health is poor, and a higher first charge threshold can be set. When the ambient temperature of the vehicle is low, the vehicle needs to consume more power to wake up, so a higher first charge threshold can also be set.

[0055] In step A3, the available battery power is calculated using vehicle parameters and a first power threshold. A first duration threshold is determined based on a first reference quiescent current and the available battery power. The first reference quiescent current is determined based on the parking duration information.

[0056] For example, the available capacity of the battery is the difference between the remaining capacity of the battery and a first capacity threshold. The first reference quiescent current can be determined based on the vehicle's parking duration information and a mapping table between parking duration and quiescent current. For example, the mapping table between parking duration and quiescent current can include multiple parking duration levels, each parking duration level corresponding to a parking duration range, and each parking duration level can correspond to a quiescent current.

[0057] If the vehicle's parking duration information includes the estimated parking duration, a corresponding parking duration level is determined based on the estimated parking duration, thereby determining the quiescent current corresponding to the parking duration level. This quiescent current is then designated as the first reference quiescent current. If the vehicle's parking duration information does not include the estimated parking duration, the maximum value of the quiescent current in the mapping table between parking duration and quiescent current can be used as the first reference quiescent current.

[0058] After determining the available battery capacity and the first reference quiescent current, the first duration threshold can be obtained by calculating the ratio of the available battery capacity to the first reference quiescent current.

[0059] It should be noted that this application uses vehicle parameters and environmental parameters to determine the first duration threshold as an example for explanation. The first duration threshold can also be a duration threshold actively set by the vehicle owner, and this application does not restrict it in this way.

[0060] The technical solution provided in this application determines a first power threshold by using vehicle parameters and environmental parameters. This allows for a more accurate determination of the first power threshold, ensuring that the vehicle can be successfully woken up under different usage conditions or parking environments, thus improving the safety and convenience of vehicle use. Determining a first duration threshold using a first reference quiescent current and the available battery power improves the accuracy of the determined first duration threshold. This facilitates the rational planning of vehicle parking time, and in subsequent processes, using the first duration threshold to determine which electronic components should be disconnected from power can better reduce the vehicle's quiescent current and extend the vehicle battery's lifespan.

[0061] In an exemplary embodiment of this application, the vehicle control system can generate control commands to control the operating state of various components of the vehicle. For example, the vehicle control system can control the Electronic Control Unit (ECU) to generate control signals through a domain controller or relay. These control signals can control the power supply and power-off of the vehicle's electronic components, wherein the vehicle's electronic components can be electrically connected to at least one ECU.

[0062] After determining the first time threshold, the actual parking time of the vehicle is compared with the first time threshold. If the actual parking time is less than the first time threshold, the vehicle control system can generate a first control signal. The first control signal is used to cut off the power supply to a first electronic component in the vehicle's electronic components. The first control signal may include at least one of the following: the name of the first electronic component, the serial number of the first electronic component, the serial number of the electronic control unit connected to the first electronic component, or the serial number of the relay connected to the first electronic component. After the power supply to the first electronic component in the vehicle's electronic components is cut off, the electronic components in the vehicle's electronic components that are in standby mode, excluding the first electronic component, can generate a first static current.

[0063] It should be noted that the first electronic component does not include the basic component. The basic component is the component used to maintain the vehicle's wake-up function. For example, the basic component can be at least one of a Bluetooth receiver or a door handle sensor. The Bluetooth receiver can be used to receive the Bluetooth signal emitted by the car key, thereby waking up the vehicle. The door handle sensor can wake up the vehicle after collecting the owner's identity information.

[0064] If the actual parking time of the vehicle is less than a first time threshold, the vehicle control system can determine that the vehicle may be restarted in a short period of time. Therefore, it can use a first control signal to cut off the power supply to non-essential electronic components (the first electronic components) that generate high static current. For example, the first electronic components may include, but are not limited to, audio components, positioning components, display components, lighting components, components related to the vehicle's air conditioning, or components related to the ventilation system.

[0065] After the vehicle is armed, the first electronic component can be in standby mode. In standby mode, this component generates quiescent current, consuming energy from the vehicle's battery. By controlling the first electronic component to cut off power supply via a first control signal, the vehicle's quiescent current can be reduced to some extent, preventing the vehicle from running out of power due to quiescent current and thus improving convenience and user experience during vehicle hibernation. Furthermore, reducing quiescent current also reduces battery energy consumption and extends battery life.

[0066] In step 203, if the actual parking time is greater than or equal to the first time threshold, a second control signal is generated. The second control signal is used to cut off the power supply to a second electronic component in the vehicle's electronic components. The second electronic component is different from the basic components.

[0067] In the exemplary embodiment of this application, when the actual parking time is greater than or equal to the first time threshold, a second control signal is generated. The process of generating the second control signal is similar to that of generating the first control signal, and will not be described in detail here. The second electronic component does not include the basic component; that is, after the power supply to the second electronic component in the vehicle's electronic components is cut off, it does not affect the vehicle's wake-up function. For a related description, please refer to the relevant description of the basic component in step 202.

[0068] If the actual parking time is greater than or equal to the first time threshold, the vehicle control system can determine that the vehicle may have a need for long-term parking. Therefore, a second control signal can be used to control a second electronic component. The second electronic component is a component that is turned off after the first electronic component is turned off. The second electronic component may include, but is not limited to, radar sensors, cameras, lidar, electronic components related to the anti-lock braking system (ABS), electronic components related to the electronic stability program (ESP), or electronic components related to the on-board charging system.

[0069] After the second electronic component in the vehicle's electronic system cuts off its power supply, the electronic components in the vehicle's electronic system that are in standby mode can generate a second static current, which is less than the first static current. In other words, the longer the vehicle is actually parked, the smaller the static current generated by the electronic components in standby mode.

[0070] It should be noted that the specific details of the first and second electronic components described in this application are illustrative and can be configured based on the actual conditions of the vehicle. Furthermore, this application uses a first or second control signal to control the corresponding electronic components to cut off power supply. Other control signals can also be used to further increase the number of electronic components that cut off power supply, and this can be configured based on the vehicle's parking duration information; this application does not impose any limitations on this.

[0071] The technical solution provided in this application generates a first control signal or a second control signal based on the actual parking time of the vehicle. The first control signal controls the first electronic component to cut off the power supply, and the second control signal controls the second electronic component to cut off the power supply. By flexibly controlling the power supply of different electronic components, the static current of the vehicle in sleep mode can be flexibly reduced, avoiding the inability to start the vehicle due to a dead battery caused by static current. This improves the convenience and user experience during the vehicle's sleep process. Furthermore, flexibly reducing static current can effectively reduce the energy consumption of the battery by static current and improve the battery's lifespan.

[0072] In an exemplary embodiment of this application, the quiescent current of the vehicle can be further reduced by a third control signal. The process of generating the third control signal may include: identifying a third electronic component among the electronic components of the vehicle, the third electronic component including at least one of a remote communication component or a quiescent current monitoring component; generating a third control signal based on relevant parameters of the third electronic component, the third control signal being used to control the periodic power supply to the third electronic component.

[0073] For example, components related to vehicle remote communication or vehicle static current monitoring are identified among the vehicle's electronic components and designated as third electronic components. For instance, the third electronic component may include at least one of a remote communication component or a static current monitoring component. The remote communication component refers to an electronic component capable of enabling communication between the vehicle and a remote server or other devices, and may include, but is not limited to, a telematics box (T-BOX), an antenna, and a controller area network interface. The static current monitoring component refers to an electronic component used to monitor the magnitude of the static current when the vehicle is in sleep mode, and may include, but is not limited to, current sensors and electronic components contained in circuits related to static current monitoring.

[0074] The system acquires relevant parameters of the third electronic component, including communication frequency, monitoring cycle, and power consumption. The vehicle control system can then use these parameters to generate a third control signal to periodically supply power to the third electronic component. For example, the third control signal can be a signal with a duty cycle. When the third control signal is high, the electronic control unit can control the battery to supply power to the third electronic component; when the third control signal is low, the electronic control unit can control the battery to cut off power supply to the vehicle's electronic components.

[0075] The following example illustrates how a vehicle can be parked for an extended period, with the third control signal controlling the power supply and de-energization of a static current monitoring device. For instance, the third control signal can be a periodic signal. Within one control cycle, the high-level signal lasts for 10 minutes, and the low-level signal lasts for 40 minutes. This means that within one control cycle, the static current monitoring device can continuously monitor the static current of the vehicle as a whole or generated by electronic components for 10 minutes, and then remain in a non-operating state for 40 minutes.

[0076] The technical solution provided in this application embodiment controls the periodic power supply to the third electronic component through a third control signal, which can further reduce the static current of the vehicle in sleep mode, thereby further reducing the energy consumption of the battery by the static current and improving the battery's service life.

[0077] In an exemplary embodiment of this application, an anomaly alert message may also be generated during the static current monitoring process. The process of generating the anomaly alert message may include: acquiring a second reference static current of the vehicle's electronic components, wherein the second reference static current is the static current generated by any electronic component of the vehicle; and generating an anomaly alert message if the second reference static current is greater than or equal to the static current threshold corresponding to the electronic component, wherein the anomaly alert message is used to alert the electronic component to an abnormal static current situation.

[0078] For example, a static current monitoring device can monitor the static current generated by any electronic component in standby mode, i.e., the second reference static current. Different electronic components generate different compliant static currents in standby mode; therefore, corresponding static current thresholds can be set for different electronic components. When the second reference static current generated by an electronic component is detected to be greater than or equal to its corresponding static current threshold, this second reference static current can be identified as an abnormal current. Based on this abnormal current, an abnormality alert is generated. The abnormality alert may include the name or number of the electronic component generating the abnormal current, and the abnormal current value (second reference current value). The abnormality alert can be sent to the vehicle owner via a mobile application or remote monitoring platform.

[0079] The technical solution provided in this application monitors the second reference static current generated by electronic components. When the second reference current is abnormal, it alerts the vehicle owner with an abnormality reminder, which helps to promptly inspect the vehicle and effectively avoid more serious faults and losses.

[0080] In an exemplary embodiment of this application, if the expected parking time is greater than a first time threshold, a fourth control signal is generated. The fourth control signal is used to cut off the power supply to a fourth electronic component in the vehicle's electronic components. The power consumption of the fourth electronic component is greater than the power consumption of the first electronic component.

[0081] For example, the first threshold duration can be set to 3 days. When the vehicle owner needs to park the vehicle for an extended period, an estimated parking duration of 30 days can be set. This directly generates a fourth control current to shut down the fourth electronic component, whose power consumption is greater than that of the first electronic component. In other words, among the vehicle's electronic components, the static current generated by the electronic components other than the fourth electronic component is less than the first static current. For example, the fourth electronic component may include the first electronic component and some or all of the second electronic components.

[0082] It should be noted that the process of generating the fourth control signal based on the estimated parking duration is similar to the process of generating the first or second control signal based on the actual parking duration, and will not be elaborated on here.

[0083] The technical solution provided in this application generates a fourth control signal based on the vehicle's expected parking time. This fourth control signal is used to control a fourth electronic component to cut off the power supply. The power consumption of the fourth electronic component is greater than that of the first electronic component, which can further reduce the energy consumption of the battery by the static current and improve the battery's service life.

[0084] Figure 3 This is a schematic diagram illustrating a vehicle static current control process provided in an embodiment of this application. Figure 3 As shown, the battery can power the vehicle controller, the first domain controller, and the second domain controller. The battery can be connected to a battery sensor, which acquires the battery's charge level and sends this information to the vehicle controller. The vehicle controller generates a first control command and a second control command based on the parking duration and charge level. The first control command controls the first domain controller to generate a first control signal, and the second control command controls the second domain controller to generate a second control signal. The first and second electronic components are electrically connected to their respective ECUs. The first and second control signals can control the corresponding ECUs to cut off power to either the first or second electronic component.

[0085] This application also provides a control device for vehicle static current. Figure 4 This is a schematic diagram of a vehicle static current control device provided in an embodiment of this application, as shown below. Figure 4 As shown, the device includes:

[0086] The acquisition module 401 is used to acquire the parking duration information of vehicles in sleep mode, including the actual parking duration.

[0087] The first generation module 402 is used to generate a first control signal when the actual parking time is less than a first time threshold. The first control signal is used to cut off the power supply to the first electronic component in the vehicle's electronic components. The vehicle's electronic components are used to generate static current. The first electronic component is different from the basic components, which are components used to maintain the vehicle's wake-up function.

[0088] The second generation module 403 is used to generate a second control signal when the actual parking time is greater than or equal to the first time threshold. The second control signal is used to cut off the power supply to the second electronic component in the vehicle's electronic components. The second electronic component is different from the basic component.

[0089] In one possible implementation, among the electronic components of the vehicle, electronic components other than the first electronic component generate a first static current, and electronic components of the vehicle other than the second electronic component generate a second static current, wherein the first static current is greater than the second static current.

[0090] In one possible implementation, the acquisition module 401 is further configured to acquire vehicle parameters and environmental parameters of the vehicle. The vehicle parameters include at least one of the total battery capacity, the remaining battery capacity, or the number of charge / discharge cycles of the battery. The environmental parameters include the ambient temperature.

[0092] The determination module is also used to calculate the available power of the battery using vehicle parameters and a first power threshold, and to determine a first duration threshold based on a first reference quiescent current and the available power of the battery. The first reference quiescent current is determined based on the parking duration information.

[0096] The device also includes a reminder module (not shown in the figure), which is used to generate an abnormal reminder message when the second reference static current is greater than or equal to the static current threshold corresponding to the electronic component. The abnormal reminder message is used to remind the electronic component of the abnormal static current.

[0097] In one possible implementation, the parking duration information also includes the estimated parking duration, which is determined based on at least one of historical parking duration or a set duration; the device also includes a fourth generation module (not shown in the figure), which is used to generate a fourth control signal when the estimated parking duration is greater than a first duration threshold. The fourth control signal is used to cut off the power supply to a fourth electronic component in the vehicle's electronic components, the power consumption of the fourth electronic component being greater than the power consumption of the first electronic component.

[0098] The technical solution provided in this application generates a first control signal or a second control signal based on the actual parking time of the vehicle. The first control signal controls the first electronic component to cut off the power supply, and the second control signal controls the second electronic component to cut off the power supply. By flexibly controlling the power supply of different electronic components, the static current of the vehicle in sleep mode can be flexibly reduced, avoiding the inability to start the vehicle due to a dead battery caused by static current. This improves the convenience and user experience during the vehicle's sleep process. Furthermore, flexibly reducing static current can effectively reduce the energy consumption of the battery by static current and improve the battery's lifespan.
