Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The vehicle quiescent current is the quiescent current of the electrical system of the vehicle, also known as dark current, and refers to the current that remains after all the electrical components have been put into a dormant state after the vehicle has been turned off. Generally, the quiescent current is in a lower current range, but in abnormal situations, such as electrical failure in a dormant state, short circuit of a circuit, etc., the quiescent current is greatly increased, the electric consumption of the storage battery is accelerated, and the storage battery is deficient, so that the vehicle cannot be started. At present, a vehicle does not have a reminding function for whether the static current abnormality exists, and a user cannot timely acquire the information of the static current abnormality.

In view of the above technical problems, an aspect of the present application provides a method for monitoring abnormal static current of a vehicle, in which voltage data of a battery is collected through a remote vehicle-mounted terminal (TELEMATICS BOX, T-Box), and the voltage data is transmitted to a remote service Provider (TELEMATICS SERVICE Provider, TSP), and the TSP performs data analysis to determine whether abnormal static current occurs, so that workload of the T-Box is reduced and operation speed is faster than that of the T-Box.

Fig. 1 is a system architecture diagram for monitoring a vehicle for a quiescent current anomaly according to an exemplary embodiment of the present application. As shown in fig. 1, the TSP communicates remotely with the user terminal and the T-Box, respectively, which is connected to the powered device. Optionally, the user terminal is a mobile phone, a computer, a tablet device, and the like.

Alternatively, the TSP may receive a static current monitoring signal for the vehicle transmitted from the user terminal, and transmit a determination result of whether the static current of the vehicle is abnormal to the user terminal. In addition, the TSP communicates with the T-Box remotely, for example, via a message queue telemetry transport protocol (Message Queuing Telemetry Transport, MQTT) or Short message service (Short MESSAGE SERVICE, SMS), for receiving the voltage signal of the battery collected by the T-Box, and analyzing the voltage signal to determine whether a quiescent current abnormality has occurred.

Fig. 2 is a schematic diagram of a system for monitoring abnormal quiescent current of a vehicle according to an exemplary embodiment of the present application. As shown in fig. 2, the system structure includes a storage battery, a storage battery sensor, electric equipment, a T-Box, a TSP, and a user terminal. The T-Box and the electric equipment are connected in parallel in the whole vehicle circuit, and the T-Box and the electric equipment jointly obey the network management strategy of a controller area network (Controller Area Network, CAN). The battery sensor is connected with the T-Box through a local internet bus (Local Interconnect Network, LIN line) or a hard wire, and transmits the collected voltage data of the battery to the T-Box. In addition, the T-Box is used as an external awakening source, and CAN receive the instruction of the TSP to carry out whole vehicle awakening, namely the CAN node of the electrical system is network management based on remote awakening of the T-Box. The electric equipment transmits working current and electrostatic current through the CAN bus.

After the vehicle is flameout, if the electric component is normally dormant, only a small amount of static current is consumed, the electric quantity of the storage battery is not changed too much, and correspondingly, the voltage is not changed too much. However, if there is an electrical component that fails to sleep normally, the quiescent current will increase substantially, accelerating the battery drain. However, since the quiescent current is the current after the electrical component is dormant, the T-Box will also go dormant after going dormant, and the quiescent current cannot be obtained, whereas the current obtained before the T-Box is not dormant is the operating current, not the quiescent current, and thus the quiescent current cannot be directly obtained. In addition, at the instant of dormancy of the electrical components, the voltage of the storage battery does not substantially change; and when the quiescent current abnormality exists, the electric quantity of the storage battery is consumed, so that the voltage is greatly reduced, and therefore, in the embodiment of the application, whether the quiescent current abnormality occurs is judged through the voltage change after the vehicle is flameout.

The vehicle is not immediately put into a dormant state after flameout, and usually enters the whole vehicle dormant state after a period of time, in the period of time, the whole vehicle system can still work normally or work with low power consumption, the T-Box can acquire voltage data of the storage battery through the storage battery sensor, the voltage data is uploaded to the TSP, and whether the static current abnormality occurs or not is analyzed by the TSP. See fig. 3 for a method of how TSP determines quiescent current anomalies.

Fig. 3 is a flowchart of a method for monitoring abnormal quiescent current of a vehicle according to an exemplary embodiment of the present application. The method is performed by a remote service provider (i.e., TSP). As shown in fig. 3, the vehicle quiescent current abnormality monitoring method in the present embodiment includes the following steps.

Step S310, first voltage data of the battery is acquired.

The first voltage data includes a first voltage and a first time at which the first voltage was collected by a remote in-vehicle terminal (i.e., T-Box). The first time is a time between when the vehicle is turned off and before the remote in-vehicle terminal is dormant. At some point between after the vehicle is turned off and before the remote in-vehicle terminal is dormant, the remote in-vehicle terminal collects a first voltage of the vehicle through the battery sensor and records a time (i.e., a first time) at which the first voltage is obtained.

Alternatively, the remote in-vehicle terminal collects the first voltage data of the vehicle at a time after each vehicle flameout and before the remote in-vehicle terminal sleeps, and uploads the collected first voltage data to the TSP, for example, to be stored in a memory of the TSP. Or after receiving the instruction of the TSP, the remote vehicle-mounted terminal collects first voltage data of the vehicle and uploads the first voltage data to the TSP, wherein the instruction can be a static current monitoring signal which is sent by the user terminal and aims at the vehicle.

Optionally, the TSP may acquire the first voltage data after each time the first voltage data uploaded by the remote vehicle-mounted terminal is received, and perform subsequent analysis. Or after receiving the static current monitoring signal sent by the user terminal and aiming at the vehicle, the TSP acquires the first voltage data uploaded by the remote vehicle-mounted terminal.

Optionally, the remote vehicle-mounted terminal uploads the first voltage data to the TSP at intervals, and the TSP performs subsequent analysis according to the uploaded first voltage data. For example, the period of time is 1 month, 2 months, half year, or the like.

Step S320, second voltage data of the battery is acquired.

The second voltage data includes a second voltage and a second time at which the second voltage was collected by the remote in-vehicle terminal (i.e., T-Box). The second time is a time between when the vehicle is next started and when the remote in-vehicle terminal wakes up. At some point between before the next start of the vehicle and after the remote in-vehicle terminal is awakened, the remote in-vehicle terminal collects a second voltage of the vehicle through the battery sensor, and records a time (i.e., a second time) at which the second voltage is collected.

The time for the T-Box to collect the second voltage corresponds to the time for the T-Box to collect the first voltage, and after the first voltage is collected, the T-Box collects the second voltage at a certain time between the time before the next starting of the vehicle and the time after the remote vehicle-mounted terminal is awakened. That is, the frequency at which the second voltage is acquired depends on the frequency at which the first voltage is acquired. For example, if the remote vehicle-mounted terminal collects the first voltage data of the vehicle before the remote vehicle-mounted terminal sleeps after each flameout, the remote vehicle-mounted terminal collects the second voltage data of the vehicle before the next start of the vehicle and at a certain time after the remote vehicle-mounted terminal wakes up, and uploads the collected second voltage data to the TSP, for example, to be stored in a memory of the TSP. And if the remote vehicle-mounted terminal receives the instruction of the TSP, acquiring the first voltage data of the vehicle and uploading the first voltage data to the TSP, and correspondingly, acquiring the second voltage data of the vehicle at a certain moment between the time before the next starting of the vehicle and the time after the remote vehicle-mounted terminal is awakened.

The TSP may acquire the first voltage data and the second voltage data simultaneously, or acquire the first voltage data and then acquire the second voltage data, or acquire the second voltage data and then acquire the first voltage data.

Step S330 determines a unit voltage drop of the battery based on the first voltage data and the second voltage data.

Even if there is no abnormality in the quiescent current after the vehicle is turned off, the voltage of the battery decreases with time, and therefore, the voltage of the battery is related to time, and a time factor needs to be considered.

First, a voltage difference between a first voltage and a second voltage is determined, a time difference for collecting the first voltage and the second voltage is determined, and a unit voltage drop of the storage battery is determined based on the voltage difference and the time difference.

Step S340 determines whether the unit voltage drop is above a voltage drop threshold. If the unit voltage drop is higher than the voltage drop threshold, step S350 is performed to determine that the quiescent current of the vehicle is abnormal. If the unit voltage drop is not higher than the voltage drop threshold, step S360 is performed to determine that the quiescent current of the vehicle is normal.

The voltage drop threshold is determined based on the unit voltage drop of the battery after the vehicle is turned off when no quiescent current anomaly exists, in combination with the battery life of the battery, etc. Typically, the voltage drop threshold is a small value, well below the unit voltage drop in the presence of quiescent current.

When no quiescent current anomaly exists, the unit voltage drop is small and is lower than the voltage drop threshold. If there is a quiescent current, the voltage will drop significantly, resulting in a larger unit voltage drop, above the voltage drop threshold. Thus, if the unit voltage drop is higher than the voltage drop threshold, determining that the quiescent current of the vehicle is abnormal; if the unit voltage is lower than the voltage drop threshold value, determining that the static current of the vehicle is normal.

Alternatively, the TSP may transmit the determination result of the quiescent current abnormality of the vehicle to the user terminal. And if the static current of the vehicle is abnormal, sending the determination result to the user terminal. And the user obtains the determination result through the user terminal and maintains the vehicle. Further, the TSP may send a determination result of the quiescent current abnormality of the vehicle to the T-Box, and alert the user of the quiescent current abnormality through the vehicle machine when the vehicle is started, so that the user can repair in time.

The embodiment of the application provides a vehicle quiescent current abnormality monitoring method, which is used for determining whether quiescent current abnormality occurs according to the condition of voltage change from flameout to the next starting of a storage battery. The static current abnormality is determined through the voltage difference of the storage battery, so that the operation is easier than the direct measurement of the static current of a single electric device, and the accuracy is higher. In addition, determining whether a quiescent current anomaly has occurred is performed by the TSP, reduces the workload of the T-Box, and operates faster than if the data analysis has been performed directly by the T-Box.

It will be appreciated that the quiescent current anomaly may not occur after the vehicle has been turned off, may occur suddenly for a period of time after the vehicle has been turned off, or may occur until the next time it is to be started. If the voltage difference between the flameout voltage and the voltage difference before the next startup voltage are directly used to determine the unit voltage drop, and further determine whether the quiescent current abnormality exists, in some cases, erroneous judgment may be caused (for example, the quiescent current abnormality occurs, but the voltage change is not obvious due to short time, so that the unit voltage is reduced below the voltage drop threshold). Therefore, after the vehicle is flameout and before the next start, the TSP can collect the voltage of the storage battery at intervals, determine a plurality of unit voltage drops, respectively compare the unit voltage drops with the voltage drop threshold value, and determine that the quiescent current is normal if the unit voltage drops are smaller than the voltage drop threshold value; if the unit voltage drop is higher than the voltage drop threshold, the quiescent current abnormality is determined. The method can further improve the accuracy of determining whether the static current is abnormal.

Fig. 4 is a flowchart of a method for acquiring voltage data based on a quiescent current monitoring signal according to an exemplary embodiment of the present application. The method is performed by a remote service provider (i.e., TSP) and includes the following steps.

Step S410, receiving a static current monitoring signal for a vehicle sent by a user terminal.

The TSP may communicate remotely with the user terminal and receive a quiescent current monitoring signal for the vehicle sent by the user terminal. Alternatively, the user may determine whether to monitor the quiescent current according to the parking time, for example, if the user is temporarily parked, for example, for 1h or 2h, the voltage change is not obvious due to the short parking time, which may result in inaccurate judgment result, and then it is not necessary to judge whether the quiescent current is abnormal. If the user stops for a long time, for example, 10 days or 15 days, the voltage will change significantly due to the longer stopping time, and then it can be determined whether the quiescent current abnormality occurs. Optionally, the user sends a quiescent current monitoring signal for the vehicle via the user terminal when it is suspected that there may be a quiescent current anomaly. Alternatively, the user may send the quiescent current monitoring signal for the vehicle periodically, e.g., the user sends the quiescent current monitoring signal for the vehicle every other month (two months or other periods).

Step S420, a quiescent current signal for the vehicle is sent to a remote on-board terminal of the vehicle, so that the remote on-board terminal collects the first voltage and the second voltage in response to the quiescent current monitoring signal for the vehicle.

The TSP, upon receiving a quiescent current signal for the vehicle, sends the signal to the remote on-board terminal (i.e., T-Box) of the vehicle. The remote in-vehicle terminal collects the first voltage and the second voltage in response to a quiescent current monitoring signal for the vehicle.

In the embodiment of the application, the static current monitoring signal sent by the user terminal and aiming at the vehicle is received and sent to the remote vehicle-mounted terminal, so that the remote vehicle-mounted terminal can collect the first voltage and the second voltage without collecting the first voltage and the second voltage after flameout each time, thereby reducing the energy consumption of the remote vehicle-mounted terminal; in addition, whether the first voltage and the second voltage are acquired or not is determined according to the wish of the user, the user requirement can be met, and the user experience is improved.

Fig. 5 is a flowchart of a method for monitoring abnormal quiescent current of a vehicle according to an exemplary embodiment of the present application. The method is performed by a remote in-vehicle terminal (i.e., T-Box), and includes the following steps.

Step S510, a first voltage of the battery at a first time is collected. The first voltage and the first time constitute first voltage data.

The first time is a time between when the vehicle is turned off and before the remote in-vehicle terminal is dormant. After the vehicle is flameout, the remote vehicle-mounted terminal of the vehicle cannot immediately enter a dormant state, and the remote vehicle-mounted terminal can acquire voltage data of the storage battery through the storage battery sensor.

Optionally, after receiving the signal of flameout of the vehicle each time, the first voltage of the storage battery at the first time is collected, so that the abnormal quiescent current can be found in time.

Optionally, in response to the received quiescent current monitoring signal for the vehicle, the first voltage of the storage battery at the first time is collected, so that the quiescent current can be monitored according to the requirement, and the energy consumption of the remote vehicle-mounted terminal is reduced.

Optionally, before the first voltage of the battery at the first time is collected, a connection state of the remote vehicle-mounted terminal and the vehicle needs to be determined, specifically, including a network connection state, whether the vehicle is powered down, and the like.

Step S520, a second voltage of the battery at a second time is collected. The second voltage and the second time constitute second voltage data.

The second time is a time between when the vehicle is next started and when the remote in-vehicle terminal wakes up. And after the remote vehicle-mounted terminal is awakened, acquiring voltage data of the storage battery through the storage battery sensor.

The second time corresponds to the first time, and if the first voltage is collected after flameout each time, the second voltage is collected correspondingly before the next starting each time. If the first voltage is collected after receiving the quiescent current monitoring signal for the vehicle, the second voltage is collected only before the next start.

Optionally, before the second voltage of the battery at the second time is collected, a connection state of the remote vehicle-mounted terminal and the vehicle needs to be determined, specifically, including a network connection state, whether the vehicle is powered down, and the like.

Step S530, the first voltage data and the second voltage data are transmitted to the remote service provider, so that the remote service provider determines a unit voltage drop of the storage battery based on the first voltage data and the second voltage data, and determines that the quiescent current of the vehicle is abnormal when the unit voltage drop is higher than the voltage drop threshold.

The remote vehicle-mounted terminal may transmit to the TSP immediately after the first voltage data or the second voltage data is acquired, or transmit to the TSP after receiving an acquisition request of the TSP. After receiving the first voltage data and the second voltage data, the TSP performs data processing analysis to judge whether the quiescent current abnormality occurs.

The embodiment of the application provides a vehicle quiescent current anomaly monitoring method, which is characterized in that voltage data of a storage battery is acquired through a T-Box and is sent to a TSP, and the T-Box is connected with a storage battery sensor, so that the voltage of the storage battery can be acquired in time, and the data are more accurate.
