[0029] 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.
[0030] This application provides a method for controlling a storage battery. Please refer to... Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: a vehicle 11 and a vehicle control system 12.
[0031] Optionally, the vehicle control system 12 acquires a first detection result, which indicates whether the vehicle 11 is in a static parking state. Based on the first detection result indicating that the vehicle is in a static parking state, the vehicle control system 12 acquires the current value of the battery of the vehicle 11 according to a reference frequency. The vehicle control system 12 controls the ZCU (Zone Control Unit) to acquire the minimum current value among the current values acquired within a first reference time period. The ZCU is located on the vehicle 11. Based on the minimum current value being greater than a first reference threshold, the vehicle control system 12 controls the reference value to be incremented by one. The reference value is used for the statistical comparison of whether the current value is greater than the first reference threshold. Based on the reference value being greater than a second reference threshold, the vehicle control system 12 controls the ZCU to put the vehicle network and controller into a reference power consumption state.
[0032] The vehicle control system 12 can store the minimum current value among the current values acquired within the first reference time period. The vehicle 11 can obtain the minimum current value from the vehicle control system 12. The minimum current value is used to compare with the first reference threshold to determine whether it is necessary to control the ZCU to put the vehicle network and controller into the reference power consumption state. Of course, the vehicle 11 can also store the minimum current value.
[0033] Optionally, the vehicle 11 and the vehicle control system 12 establish a communication connection via a wired or wireless network.
[0034] Those skilled in the art should understand that the above-described vehicle 11 and vehicle control system 12 are merely examples. Other existing or future vehicles 11 or vehicle control systems 12 that are applicable to this application should also be included within the scope of protection of this application, and are hereby incorporated by reference.
[0035] Based on the above Figure 1 The implementation environment shown in this application embodiment provides a method for controlling a storage battery, such as... Figure 2 As shown, taking the application of this method to a vehicle control system as an example, the method includes steps 201-205.
[0036] In step 201, a first detection result is obtained, which is used to indicate whether the vehicle is in a static parking state.
[0037] The first detection result is used to indicate whether the vehicle is in a static parking state. In one possible implementation, obtaining the first detection result includes: obtaining a second detection result and a third detection result, wherein the second detection result is used to indicate whether the vehicle is in a power-off state, and the third detection result is used to indicate whether the vehicle is in a network sleep state, where the network sleep state is a state without bus activity; based on the second detection result indicating that the vehicle is in a power-off state and the third detection result indicating that the vehicle is in a network sleep state, the first detection result indicates that the vehicle is in a static parking state.
[0038] For example, obtaining a second detection result for indicating whether the vehicle is in a power-off state includes: judging the power-on / off state of the vehicle by the position of the vehicle's ignition switch; the vehicle control system obtains the position information of the ignition switch; when the ignition switch is in the OFF position, the second detection result indicates that the vehicle is in a power-off state; when the ignition switch is in the ON position, the second detection result indicates that the vehicle is not in a power-off state.
[0039] In one possible implementation, the vehicle control device obtains the ignition switch position information in ways including, but not limited to, detecting the ignition switch position information via the CAN (Controller Area Network) bus. When the ignition switch is detected to be in the OFF position, a third detection result indicates that the vehicle is powered off; when the ignition switch is detected to be in the ON position, a second detection result indicates that the vehicle is not powered off.
[0040] Optionally, obtaining a third detection result to indicate whether the vehicle is in a network sleep state includes: determining whether there is data transmission or signal transmission on the detection bus, and obtaining a fourth, fifth, or sixth detection result. The fourth detection result is used to indicate whether there is a signal change on the data line of the CAN bus, the fifth detection result is used to indicate whether there is a signal change on the clock line of the CAN bus, and the sixth detection result is used to indicate whether there is a signal change on the control line of the CAN bus.
[0041] If the fourth detection result indicates no signal change on the CAN data line, the fifth detection result indicates no signal change on the CAN clock line, and the sixth detection result indicates no signal change on the CAN control line, then the third detection result indicates the vehicle is in network sleep mode. If the fourth detection result indicates a signal change on the CAN data line, the fifth detection result indicates a signal change on the CAN clock line, or the sixth detection result indicates a signal change on the CAN control line, then the third detection result indicates the vehicle is not in network sleep mode.
[0042] In step 202, based on the first detection result indicating that the vehicle is in a static parking state, the current value of the vehicle's battery is obtained according to the reference frequency.
[0043] In one possible implementation, after determining that the first detection result indicates the vehicle is in a static parking state, the vehicle's battery current value is acquired at a reference frequency. This includes: the vehicle control system controlling the EBS (Electronic Brake Systems) to acquire the battery current value via an ammeter at the reference frequency. The ammeter is located on the vehicle; when detecting the battery current, the positive terminal of the ammeter is connected to the positive terminal of the battery, and the negative terminal of the ammeter is connected to the negative terminal of the battery. The ammeter reading is then used as the battery current value. After the EBS acquires the battery current value, the vehicle control system reads the battery current value acquired by the EBS.
[0044] For example, after EBS obtains the current value of the battery according to the reference frequency, it stores the minimum current value among the obtained current values of the battery every first reference time interval.
[0045] This application does not limit the reference frequency. For example, the reference frequency can be set based on experience, such as 10 seconds, or it can be adjusted according to actual conditions. This application also does not limit the first reference duration. For example, the first reference duration can be set based on experience, or it can be adjusted according to actual conditions.
[0046] In step 203, the ZCU is controlled to acquire the minimum current value among the current values acquired within the first reference time period. The ZCU is located on the vehicle.
[0047] In one possible implementation, the vehicle control system wakes up the ZCU and controls the ZCU to obtain the minimum current value among the battery current values obtained within a first reference time period from the vehicle control system, wherein the ZCU is located on the vehicle and controls the vehicle network and the controllers on the vehicle.
[0048] Optionally, the vehicle control system may wake up the ZCU by sending a wake-up signal to the ZCU, including but not limited to the method of waking up the ZCU by the vehicle control system.
[0049] In step 204, based on the minimum current value being greater than the first reference threshold, the reference value is incremented by one. The reference value is used to statistically analyze the comparison results of whether the current value is greater than the first reference threshold.
[0050] In one possible implementation, the vehicle control system controls the ZCU to compare the minimum current value among the battery current values acquired within a first reference time period with a first reference threshold. If the minimum current value is greater than the first reference threshold, the control reference value is incremented by one. The reference value is used to statistically determine whether the current value is greater than the first reference threshold. In each comparison between the minimum current value and the first reference threshold, if the minimum current value is greater than the first reference threshold, the control reference value is incremented by one.
[0051] For example, based on a minimum current value being less than or equal to a first reference threshold, the ZCU is controlled to switch to a sleep state. The sleep state is a state in which the ZCU transfers the data in memory to the hard disk and shuts off the power supply to all devices except the memory. Optionally, the method of controlling the ZCU to switch to a sleep state includes, but is not limited to, the vehicle control system sending a sleep command to the ZCU.
[0052] This application does not restrict the initial value of the reference value; the reference value can be any integer. This application also does not restrict the first reference threshold; for example, the first reference threshold can be set based on experience, or it can be adjusted according to actual circumstances.
[0053] In step 205, based on the reference value being greater than the second reference threshold, the ZCU is controlled to bring the vehicle network and controller into the reference power consumption state.
[0054] In one possible implementation, the vehicle control system controls the ZCU to compare a reference value with a second reference threshold. If the reference value is greater than the second reference threshold, the ZCU controls the vehicle network and controller to enter a reference power consumption state. For example, the reference value is obtained by subtracting the original reference value from the increased reference value.
[0055] The methods by which the ZCU (Zero Control Unit) is controlled to bring the vehicle network and controller into a reference power consumption state include, but are not limited to: the vehicle control system controlling the ZCU to send a sleep command to the vehicle network and controller, thus putting them into a sleep state. In the sleep state, both the vehicle network and controller are in a reference power consumption state, where the power consumption is lower than a reference power consumption level. In this state, the current of the ECU (Electronic Control Unit) and the quiescent current of the controller decrease. Optionally, the reference power consumption setting may include, but is not limited to, an empirically based setting.
[0056] After the vehicle network and controller enter the reference power consumption state, the vehicle control system restores the control reference value to the value before the increase, which is used for the next statistical comparison of whether the current value is greater than the first reference threshold.
[0057] For example, based on a reference value being less than or equal to a second reference threshold, the ZCU is controlled to switch to a sleep state. For example, the vehicle control system controls the ZCU to switch to a sleep state in accordance with step 204. After the ZCU switches to a sleep state, the vehicle control system controls the vehicle not to acquire and compare the battery current value for a second reference duration, and the EBS clears the stored minimum current value before switching to a sleep state, so that the minimum current value can be acquired again after the second reference duration.
[0058] This application does not impose any limitations on the second reference threshold. For example, the second reference threshold can be set based on experience, or it can be adjusted according to actual circumstances. Similarly, this application does not impose any limitations on the second reference duration. For example, the second reference duration can be set based on experience, or it can be adjusted according to actual circumstances.
[0059] Figure 3 A strategy diagram for controlling a storage battery is provided. Specifically, when the vehicle is in a static parking state, i.e., the vehicle is powered off and the network is in sleep state 301, the EBS acquires the current value of the vehicle's battery according to a reference frequency 302, and the EBS stores the minimum current value among the acquired battery current values every first reference time interval 303.
[0060] Determine whether the minimum current value is greater than the first reference threshold 304. If the minimum current value is greater than the first reference threshold, control the reference value to be incremented by one 305. If the minimum current value is less than or equal to the first reference threshold, EBS obtains the current value of the vehicle's battery according to the reference frequency 302.
[0061] 305. If the reference value is greater than the second reference value, the ZCU is controlled to put the vehicle network and controller into the reference power consumption state. 307. If the reference value is less than or equal to the second reference value, the EBS obtains the current value of the vehicle's battery according to the reference frequency.
[0062] This application embodiment obtains a first detection result indicating whether the vehicle is in a static parking state. If the first detection result indicates that the vehicle is in a static parking state, the current value of the vehicle's battery is obtained according to a reference frequency, thereby realizing the monitoring of the battery current value according to the reference frequency.
[0063] By controlling the ZCU to obtain the minimum current value among the current values acquired within a first reference time period, if the minimum current value is greater than the first reference threshold, the reference value is incremented by one. When the reference value exceeds the second reference threshold, indicating excessive battery current, the ZCU is controlled to put the vehicle network and controller into a reference power consumption state, thereby controlling the battery current. By detecting the magnitude of the battery's quiescent current and inducing the vehicle network and controller into a reference power consumption state, the loss of battery charge is controlled, thus preventing battery depletion.
[0064] See Figure 4 This application provides a device for controlling a storage battery, the device comprising:
[0065] The first acquisition module 401 is used to acquire a first detection result, which indicates whether the vehicle is in a static parking state.
[0066] The second acquisition module 402 is used to acquire the current value of the vehicle's battery according to a reference frequency based on the first detection result indicating that the vehicle is in a static parking state.
[0067] The third acquisition module 403 is used to control the area control unit ZCU to acquire the minimum current value among the current values acquired within the first reference time period. The ZCU is located on the vehicle.
[0068] The first control module 404 is used to control the reference value to be incremented by one based on the minimum current value being greater than the first reference threshold. The reference value is used for the statistical analysis of the comparison results of whether the current value is greater than the first reference threshold.
[0069] The second control module 405 is used to control the ZCU to make the vehicle network and controller enter the reference power consumption state based on the reference value being greater than the second reference threshold.
[0070] In one possible implementation, the first acquisition module 401 is used to acquire a second detection result and a third detection result. The second detection result is used to indicate whether the vehicle is in a power-off state, and the third detection result is used to indicate whether the vehicle is in a network sleep state, which is a state without bus activity. Based on the second detection result indicating that the vehicle is in a power-off state and the third detection result indicating that the vehicle is in a network sleep state, the first detection result indicates that the vehicle is in a static parking state.
[0071] In one possible implementation, the third acquisition module 403 is also used to control the ZCU to switch to a sleep state based on the minimum current value being less than or equal to a first reference threshold. The sleep state is a state in which the ZCU transfers the data in memory to the hard disk and shuts off the power supply to all devices except the memory.
[0072] In one possible implementation, the first control module 404 is also used to control the ZCU to switch to sleep mode based on a reference value being less than or equal to a second reference threshold.
[0073] In one possible implementation, the second control module 405 is also used to control the reference value to be restored to the value before the increase.
[0074] This device acquires a first detection result indicating whether the vehicle is in a static parking state. If the first detection result indicates that the vehicle is in a static parking state, it acquires the current value of the vehicle's battery according to a reference frequency, thereby realizing the monitoring of the battery current value according to the reference frequency.
[0075] By controlling the ZCU to obtain the minimum current value among the current values acquired within a first reference time period, if the minimum current value is greater than the first reference threshold, the reference value is incremented by one. When the reference value exceeds the second reference threshold, indicating excessive battery current, the ZCU is controlled to put the vehicle network and controller into a reference power consumption state, thereby controlling the battery current. By detecting the magnitude of the battery's quiescent current and inducing the vehicle network and controller into a reference power consumption state, the loss of battery charge is controlled, thus preventing battery depletion.

[0092] The gyroscope sensor 1511 can detect the terminal's orientation and rotation angle. The gyroscope sensor 1511 can work in conjunction with the accelerometer sensor 1510 to collect the user's 3D movements on the terminal. Based on the data collected by the gyroscope sensor 1511, the processor 1501 can perform the following functions: motion sensing (e.g., changing the UI based on the user's tilt), image stabilization during shooting, game control, and inertial navigation.
[0093] The pressure sensor 1512 can be disposed on the side bezel of the terminal and / or the lower layer of the display screen 1505. When the pressure sensor 1512 is disposed on the side bezel of the terminal, it can detect the user's grip signal on the terminal, and the processor 1501 can perform left / right hand recognition or quick operation based on the grip signal collected by the pressure sensor 1512. When the pressure sensor 1512 is disposed on the lower layer of the display screen 1505, the processor 1501 can control the operable controls on the UI interface based on the user's pressure operation on the display screen 1505. The operable controls include at least one of button controls, scroll bar controls, icon controls, and menu controls.
[0094] Optical sensor 1513 is used to collect ambient light intensity. In one embodiment, processor 1501 can control the display brightness of display screen 1505 based on the ambient light intensity collected by optical sensor 1513. Specifically, when the ambient light intensity is high, the display brightness of display screen 1505 is increased; when the ambient light intensity is low, the display brightness of display screen 1505 is decreased. In another embodiment, processor 1501 can also dynamically adjust the shooting parameters of camera assembly 1506 based on the ambient light intensity collected by optical sensor 1513.
[0095] The proximity sensor 1514, also known as a distance sensor, is typically installed on the front panel of the terminal. The proximity sensor 1514 is used to detect the distance between the user and the front of the terminal. In one embodiment, when the proximity sensor 1514 detects that the distance between the user and the front of the terminal is gradually decreasing, the processor 1501 controls the display screen 1505 to switch from a screen-on state to a screen-off state; when the proximity sensor 1514 detects that the distance between the user and the front of the terminal is gradually increasing, the processor 1501 controls the display screen 1505 to switch from a screen-off state to a screen-on state.
