The vehicles are classified according to power sources of the vehicles, and the vehicles can be new energy vehicles, including pure electric vehicles, plug-in hybrid electric vehicles, fuel cell electric vehicles and the like. A plurality of vehicle-mounted systems are installed in the vehicle, including a brake-by-wire system, a battery management system, a vehicle controller system and the like. The in-vehicle terminal 102 CAN receive vehicle condition information corresponding to other in-vehicle systems in the vehicle through a CAN (Controller Area Network ) line in the vehicle.
Fig. 2 is a flowchart of a vehicle condition information query method according to an embodiment of the present application, and as shown in fig. 2, in the embodiment of the present application, an example of execution by a vehicle-mounted terminal is described. The vehicle control method includes the steps of:
201. in response to a vehicle condition query request of the terminal, the vehicle-mounted terminal acquires vehicle condition information of a vehicle, the vehicle condition information being used for reflecting states of a plurality of vehicle-mounted systems of the vehicle.
In the embodiment of the application, the terminal is provided with the vehicle condition query application, and the vehicle condition query application can query the vehicle condition information of the vehicle which is in wireless connection with the terminal. Accordingly, based on the vehicle condition query application, the terminal can generate a vehicle condition query request. Since the vehicle condition query request is for requesting acquisition of the vehicle condition information of the vehicle, the vehicle-mounted terminal can acquire the vehicle condition information of the vehicle in response to the vehicle condition query request. The vehicle condition information includes various types of information such as tire pressure state, tire temperature state, sunroof and window state, high-voltage system failure state, power battery system failure state, front/rear power system failure state, charge state, etc. The plurality of vehicle-mounted systems of the vehicle comprise a vehicle-mounted communication system, a line control and braking system, an electric drive system, a battery management system, a vehicle control unit system and the like.
The vehicle condition inquiry application displays a vehicle condition inquiry interface which is used for displaying vehicle condition information of the vehicle. Optionally, the terminal can generate the vehicle condition query request in response to an update operation on the vehicle condition query interface.
Alternatively, in the case where the vehicle does not receive the vehicle condition query request of the terminal, the vehicle-mounted terminal may periodically acquire the vehicle condition information of the vehicle, so as to periodically detect a plurality of vehicle-mounted systems in the vehicle. In the case of detecting that an abnormality occurs in the vehicle-mounted system, the vehicle-mounted terminal may directly transmit abnormality information of the vehicle to the terminal.
202. When the state of at least one vehicle-mounted system is abnormal, the vehicle-mounted terminal determines at least one piece of abnormality information based on the vehicle condition information.
In the embodiment of the application, since the vehicle condition information is used for reflecting the states of a plurality of vehicle-mounted systems of the vehicle, the vehicle-mounted terminal can determine whether each vehicle-mounted system of the vehicle is abnormal or not based on the vehicle condition information. Further, in the case where the state of at least one of the vehicle-mounted systems is an abnormal state, that is, in the case where an abnormality occurs in at least one of the vehicle-mounted systems, the vehicle-mounted terminal can determine at least one piece of abnormality information based on the vehicle condition information corresponding to the at least one of the vehicle-mounted systems in which the abnormality occurs. The abnormality information includes various types of information such as an excessively low amount of electricity of the vehicle, a malfunction of a power system of the vehicle, an abnormality of tire pressure of the tire, a malfunction of an airbag system of the vehicle, and the like. Alternatively, in the case where the states of the plurality of in-vehicle systems of the vehicle are normal states, the in-vehicle terminal can generate the prompt information for prompting the user that the current state of the vehicle is normal.
203. The vehicle-mounted terminal sends at least one piece of abnormal information to the terminal, and the terminal is used for displaying the at least one piece of abnormal information.
In the embodiment of the application, the vehicle-mounted terminal can send various information of the vehicle to the terminal based on wireless connection between the vehicle-mounted terminal and the terminal. The user may not travel using the vehicle due to at least one piece of abnormal information of the vehicle. Therefore, in order not to influence the travel plan of the user, the vehicle-mounted terminal can send at least one piece of abnormal information to the terminal based on the wireless connection, and the terminal displays the at least one piece of abnormal information for the user to watch. Alternatively, the in-vehicle terminal transmits at least one piece of abnormality information to the server, and the server transmits the at least one piece of abnormality information to the terminal.
The embodiment of the application provides a vehicle condition information query method, which enables a vehicle-mounted terminal to respond to a vehicle condition query request by receiving the vehicle condition query request generated by the terminal to acquire vehicle condition information of a vehicle. Since the vehicle condition information is used to reflect the states of a plurality of in-vehicle systems of the vehicle, the in-vehicle terminal can determine whether or not an abnormality has occurred in each of the in-vehicle systems of the vehicle based on the vehicle condition information. That is, when the state of at least one in-vehicle system is an abnormal state, the in-vehicle terminal can transmit at least one piece of abnormality information determined based on the vehicle condition information to the terminal, and the terminal can display the abnormality information. And by watching the abnormal information, a user can know the state of the vehicle in advance, and the situation that the travel plan is influenced by the vehicle fault is avoided.
Fig. 3 is a flowchart of a vehicle condition information query method according to an embodiment of the present application, and as shown in fig. 3, in the embodiment of the present application, an example of the vehicle condition information query method is described. The vehicle condition information query method comprises the following steps:
301. responding to a vehicle condition query request of the terminal, and under the condition that the vehicle is in a dormant state, the vehicle-mounted terminal sends remote wake-up signals to a plurality of vehicle-mounted systems of the vehicle, wherein the remote wake-up signals are used for remotely waking up the vehicle-mounted systems.
In the embodiment of the application, the terminal is provided with the vehicle condition query application, and the vehicle condition query application can query the vehicle condition information of the vehicle which is in wireless connection with the terminal. Accordingly, based on the vehicle condition query application, the terminal can generate a vehicle condition query request. Since the power source of the vehicle is off, that is, the vehicle is in a dormant state, a plurality of in-vehicle systems mounted in the vehicle are also in a dormant state. At this time, the vehicle-mounted terminal cannot acquire the vehicle condition information based on the vehicle condition query request. Therefore, in order to wake up the vehicle from the sleep state, the in-vehicle terminal needs to transmit a remote wake-up signal to a plurality of in-vehicle systems of the vehicle. The vehicle-mounted system of the vehicle comprises a brake-by-wire system, a battery management system, an electric drive system, a vehicle body domain controller system, an intelligent cabin system, a whole vehicle controller system, an air bag controller system, an electric steering system and the like.
302. The in-vehicle terminal adjusts the state of the vehicle to a non-sleep state based on the remote wake-up signal.
In this embodiment of the present application, since the remote wake-up signal is used to wake up the vehicle-mounted system of the vehicle, the vehicle-mounted system is capable of releasing the sleep state of the vehicle in response to the remote wake-up signal, that is, based on the remote wake-up signal, the vehicle-mounted terminal is capable of adjusting the state of the vehicle from the sleep state to the non-sleep state, and the power supply of the vehicle is turned on.
303. When the state of the vehicle has been adjusted to the non-sleep state, the in-vehicle terminal acquires vehicle condition information reflecting the states of a plurality of in-vehicle systems of the vehicle.
In the embodiment of the application, in the case that the state of the vehicle has been adjusted to the non-sleep state, it is indicated that a plurality of in-vehicle systems of the vehicle have been awakened from the sleep state based on the remote wake-up signal at this time. Therefore, the in-vehicle terminal can acquire the vehicle condition information of the vehicle based on the vehicle condition query request at this time. The vehicle condition information includes various types of information such as tire pressure state, tire temperature state, sunroof and window state, high-voltage system failure state, power battery system failure state, front/rear power system failure state, charge state, etc.
In some embodiments, the vehicle-mounted terminal can acquire different types of vehicle condition information under different conditions. Correspondingly, responding to a vehicle condition query request of the terminal, and acquiring vehicle condition information by the vehicle-mounted terminal under the condition that the time interval between the current time point and the historical time point is larger than a time threshold value; and under the condition that the time interval is not greater than the time threshold value, the vehicle-mounted terminal acquires the vehicle condition information of the current time point based on the historical vehicle condition information acquired at the historical time point.
The current time point is the time point when the vehicle-mounted terminal receives the vehicle condition query request this time, and the historical time point is the time point when the vehicle-mounted terminal receives the vehicle condition query request last time. Based on the current time point and the historical time point, the vehicle-mounted terminal can determine the time interval between the current receiving of the vehicle condition query request and the last receiving of the vehicle condition query request, and further can determine the time interval of the vehicle-mounted terminal for acquiring the vehicle condition information. Since the vehicle condition information includes a plurality of types of information, some of which are strong in stability, such vehicle condition information does not change in a short time. Such as an airbag condition, a powertrain condition, a tire temperature and pressure condition, etc. Another part of the types of the vehicle condition information are poor in stability, and the vehicle condition information is easy to change in a short time. Such as a vehicle armed state, a vehicle window state, a vehicle remaining power, etc. Therefore, when the time interval between the current time point and the historical time point is greater than the time threshold, it is indicated that the time interval between the current acquisition of the vehicle condition information and the last acquisition of the vehicle condition information is longer. That is, the time interval is elapsed, not only a part of the less stable vehicle condition information among the vehicle condition information may be changed, but also another part of the more stable vehicle condition information may be changed. Therefore, the vehicle-mounted terminal needs to acquire all the vehicle condition information at this time. And under the condition that the time interval between the current time point and the historical time point is not greater than the time threshold, the time interval between the current acquisition of the vehicle condition information and the last acquisition of the vehicle condition information is short. That is, some of the more stable vehicle condition information is not changed and other less stable vehicle condition information is changed over the time interval. Therefore, the vehicle-mounted terminal does not need to acquire all the vehicle condition information, but determines the type of the vehicle condition information acquired last time based on the history vehicle condition information acquired at the history time point. And further obtains corresponding vehicle condition information. The time interval for acquiring the vehicle condition information by the vehicle is determined, so that the vehicle condition information of the vehicle can be selectively acquired, the bandwidth required by transmitting the vehicle condition information is reduced, and the acquisition speed of the vehicle condition information is increased.
304. When the state of at least one vehicle-mounted system is abnormal, the vehicle-mounted terminal determines at least one piece of abnormality information based on the vehicle condition information.
In the embodiment of the application, since the vehicle condition information is used for reflecting the states of a plurality of vehicle-mounted systems of the vehicle, the vehicle-mounted terminal can determine whether each vehicle-mounted system of the vehicle is abnormal or not based on the vehicle condition information. Further, in the case where the state of at least one of the vehicle-mounted systems is an abnormal state, that is, in the case where an abnormality occurs in at least one of the vehicle-mounted systems, the vehicle-mounted terminal can determine at least one piece of abnormality information based on the vehicle condition information corresponding to the at least one of the vehicle-mounted systems in which the abnormality occurs. The abnormality information includes various types of information such as an excessively low amount of electricity of the vehicle, a malfunction of a power system of the vehicle, an abnormality of tire pressure of the tire, a malfunction of an airbag system of the vehicle, and the like.
305. The vehicle-mounted terminal determines an abnormality level of the at least one piece of abnormality information based on an abnormality type of the at least one piece of abnormality information.
In the embodiment of the present application, since the abnormality information includes a plurality of types, the degree of influence of different types of abnormality information on the vehicle is also different. Therefore, the in-vehicle terminal can determine the degree of influence of the abnormality information on the vehicle based on the type of the abnormality information, and further determine the abnormality level of the abnormality information. Wherein, the higher the influence degree of the abnormal information on the vehicle is, the higher the abnormal grade of the abnormal information is; the lower the degree of influence of the abnormality information on the vehicle, the lower the abnormality level of the abnormality information. For example, the abnormality information of which abnormality level is high includes a failure of the power system, a failure of the high-voltage system, a failure of the brake, and the like. The abnormal information with lower abnormal level comprises that the electric quantity of the vehicle is too low, the windows of the vehicle are not closed, the fortification state of the vehicle is not opened, and the like.
306. The vehicle-mounted terminal sorts at least one piece of abnormality information from high to low based on the abnormality level.
In this embodiment of the present application, after determining the abnormality level of at least one piece of abnormality information, the vehicle-mounted terminal may sort the abnormality information according to the level of the abnormality level. Wherein, the higher the abnormality level of the abnormality information, the earlier the ordering of the abnormality information; the lower the anomaly level, the later the ordering of anomaly information.
307. And the vehicle-mounted terminal sends at least one piece of abnormal information to the terminal based on the sequencing result, and the terminal is used for displaying the at least one piece of abnormal information in sequence based on the sequencing result.
In the embodiment of the present application, since the abnormality level of at least one piece of abnormality information is different, the degree of influence of abnormality information on the vehicle is also different. Therefore, in the case where abnormality information having a high abnormality level appears, the degree of influence of the abnormality information on the vehicle is high. Indicating that the vehicle may fail, and requiring a professional to repair the vehicle. In the case where abnormality information having a low abnormality level appears, the degree of influence of the abnormality information on the vehicle is low. The vehicle is indicated to have no serious problem, and the user can solve the abnormal information by himself. Further, the vehicle-mounted terminal needs to preferentially transmit the abnormality information with higher abnormality level to the terminal, and then transmit the abnormality information with lower abnormality level. That is, the in-vehicle terminal can transmit at least one piece of abnormality information to the terminal based on the result of the sorting. The terminal can display the abnormal information with higher abnormal grade preferentially for the user to watch.
In some embodiments, the in-vehicle terminal can selectively send part of the anomaly information to the terminal. Correspondingly, the vehicle-mounted terminal sends target abnormal information with the abnormal grade larger than the grade threshold value in at least one piece of abnormal information to the terminal, and the terminal is used for displaying the target abnormal information. Wherein, because the abnormality grade of part of abnormality information in at least one piece of abnormality information is lower, the influence degree of this part of abnormality information on the vehicle is lower. The in-vehicle terminal may not transmit the part of the abnormality information to the terminal. That is, the in-vehicle terminal can transmit the target abnormality information that the abnormality level is greater than the level threshold value in the at least one piece of abnormality information to the terminal. The degree of influence of the target abnormality information on the vehicle is high. By selectively transmitting the abnormality information, the bandwidth required for transmitting the abnormality information can be saved, and the transmission speed of the abnormality information can be increased.
In some embodiments, the vehicle-mounted terminal is further capable of generating a corresponding solution according to the anomaly information and transmitting the solution to the terminal. Accordingly, for any one of the at least one piece of abnormality information, the in-vehicle terminal transmits maintenance information for solving the abnormality information to the terminal in the case where the abnormality level of the abnormality information is greater than the level threshold; in the case where the abnormality level of the abnormality information is not greater than the level threshold, the vehicle transmits the article information related to the abnormality information to the terminal. Wherein, for the abnormal information with the abnormal grade larger than the grade threshold value, the influence degree of the abnormal information on the vehicle is higher, which indicates that the vehicle may malfunction. The in-vehicle terminal can generate maintenance information for solving the abnormality information and transmit the maintenance information to the terminal. For example, the repair information may include location information of a vehicle repair shop located near the vehicle, specific equipment in the vehicle that needs to be repaired, preparation work the vehicle needs to do before repair, and the like. For the abnormal information with the abnormal grade not larger than the grade threshold, the influence degree of the abnormal information on the vehicle is low, so that the vehicle is likely to be in fault. The vehicle is indicated to have no serious problem, and the user can solve the abnormal information by himself. The in-vehicle terminal can thus generate item information related to the abnormality information and transmit the item information to the terminal. For example, the item information may be a purchase link of the item, or may be a link of an online store or location information of an offline store. By sending a solution measure for solving the abnormality of the vehicle to the terminal, the user can solve the abnormal state of the vehicle by executing the solution measure, so that the vehicle can be restored to the normal state as soon as possible, and the user can travel by taking the vehicle as soon as possible.
In some embodiments, the vehicle-mounted terminal can send the vehicle condition information to the terminal if it is determined that everything is normal based on the vehicle condition information. Accordingly, when the states of the plurality of vehicle-mounted systems of the vehicle are normal, the vehicle-mounted terminal transmits the vehicle condition information to the terminal, and the terminal is used for displaying the vehicle condition information. When the state of the plurality of in-vehicle systems of the vehicle is normal, it is indicated that the plurality of in-vehicle systems of the vehicle are not abnormal. At this time, the vehicle can send the vehicle condition information to the terminal for the user to watch.
The embodiment of the application provides a vehicle condition information query method, which enables a vehicle-mounted terminal to respond to a vehicle condition query request by receiving the vehicle condition query request generated by the terminal to acquire vehicle condition information of a vehicle. Since the vehicle condition information is used to reflect the states of a plurality of in-vehicle systems of the vehicle, the in-vehicle terminal can determine whether or not an abnormality has occurred in each of the in-vehicle systems of the vehicle based on the vehicle condition information. That is, when the state of at least one in-vehicle system is an abnormal state, the in-vehicle terminal can transmit at least one piece of abnormality information determined based on the vehicle condition information to the terminal, and the terminal can display the abnormality information. And by watching the abnormal information, a user can know the state of the vehicle in advance, and the situation that the travel plan is influenced by the vehicle fault is avoided.
On the basis of the above embodiment, the embodiment of the application further provides a system block diagram of a vehicle condition information inquiry system, as shown in fig. 4, where the vehicle condition information inquiry system includes a terminal, a TBOX (Telematics Box, vehicle terminal), a CEM (Central Electronic Module, vehicle body controller system), a BMS (Battery Management System ), an FMCU & RMCU (Front Motor Control Unit & Rare Motor Control Unit, electric drive system), a WCBS/IPB (Wire-Controlled Brake System/Integrated Power Brake, wire-controlled brake system), an IHU/ICM (Infotainment Head Unit/Ignition Control Module, intelligent cabin system), a VCU (Vehicle control unit, whole vehicle controller system), an ABM (Air Bag Module, air Bag controller system), an EPS (Electric Power Steering, electric steering system).
The TBOX CAN receive a remote vehicle condition inquiry request of the terminal through the wireless network, and wake up other vehicle-mounted systems of the vehicle through the CAN line. The TBOX CAN also collect the current vehicle condition information through the CAN line and send the vehicle condition information to the terminal. After being awakened by the TBOX remotely through the CAN line, the CEM transmits information of the vehicle fortification state, the key power mode, the four-door front hatch cover, the back door, the charging cover plate opening and closing state, the skylight and the vehicle window state and the tire pressure and tire temperature to the TBOX through the CAN line. After the BMS is remotely awakened by the TBOX through the CAN line, the BMS sends the current charge state information to the TBOX through the CAN line. After being awakened by the TBOX remotely through the CAN line, the FMCU and the RMCU send the current system fault state information to the VCU through the CAN line, and then the VCU sends the current system fault state information to the TBOX. After the WCBS/IPB is awakened by the TBOX remotely through the CAN line, the WCBS/IPB sends the current fault state of the brake system, the fault state of the ABS (Anti-lock Brake System ) and the fault state information of the ESP (Electronic Stability Program, body stability control system) to the TBOX through the CAN line. The IHU/ICM sends the total mileage information to the TBOX through the CAN line after being remotely awakened by the TBOX through the CAN line.
