The control terminal may be a mobile terminal, such as a 3G terminal, a CDMA terminal, a GSM terminal or other mobile terminal, and may specifically be a 2G or 3G mobile phone.

4 is a flow chart showing another embodiment of a method in accordance with the present invention for remote control of a user to remotely control car ignition. As shown in FIG. 4, the method includes the following steps:

Step 402: The user initiates an instruction of the remote operation terminal, that is, the owner remotely uses the remote control terminal to send a control message to the wireless communication module in the in-vehicle gateway, and the control message requests to turn the ignition component in the vehicle into an open state.

For example, the short message of the 2G or 3G terminal may be used, or may be sent to the gateway through one or more of GPRS, USSD mode, etc., and the specific wireless communication mode may be determined by the actual environment in which the user is located.

Step 404: The wireless communication module determines whether an instruction from the terminal is received, and if yes, proceeds to step 406, otherwise returns to continue determining.

The wireless communication module refers to a wireless communication module of the vehicle gateway, and the wireless communication module starts different threads to receive remote control commands from the user (eg, receiving a short message is a thread, and receiving GPRS is a thread). For different control commands received in each thread, the car gateway will It is buffered and then sent sequentially to the data processing module of the in-vehicle gateway.

Step 406: The data processing module parses the instruction, parses the control message into a message format recognizable by the vehicle network element, and sends the message to the vehicle network access module.

Step 408: The vehicle network access module sends the command to the corresponding vehicle network element.

After receiving the message, the vehicle network access module parses the control message. When the control message is sent to the ignition component of the car, the appropriate short-range wireless communication transmission mode is selected to send the control message to the vehicle network. The wireless access module of the yuan (automobile ignition component); since the vehicle gateway and the vehicle network element are installed in the vehicle body, it can be realized by one or more wireless local area network communication technologies such as 802.11, Bluetooth, and infrared. For the components in the engine such as the engine and the fuel tank, it is necessary to penetrate the vehicle body. The vehicle network access module selects the Bluetooth mode to send the control message to the wireless access module of the vehicle network element; for the audio, the seat and other components, the penetration is not required. The vehicle body and the distance are relatively close, and the vehicle network access module selects the infrared mode to send the control message to the wireless access module of the vehicle network element, so that not only the optimal transmission mode for different components but also the cost can be saved.

Step 410: The wireless access module determines whether an instruction from the in-vehicle gateway is received, and if yes, proceeds to step 412; otherwise, returns to continue determining.

Step 412: Drive the corresponding component device.

The wireless access module of the vehicle network element transmits the control message received by the short-range wireless transmission mode to the component control module of the vehicle network element. The wireless access module of each in-vehicle network element integrates appropriate short-range wireless communication hardware devices according to which specific components are specifically controlled or monitored, such as controlling the car ignition component to communicate with the gateway using Bluetooth. The component control module sends the control command to the component function drive module; the component function drive module controls the saturation and conduction of the high power transistor after receiving the ignition command, so that the primary current of the ignition coil is suddenly reduced to zero, so that the secondary coil is generated very much. High voltage, sparking through spark plug discharge.

Step 414: The in-vehicle gateway determines whether the instruction sent by the network element is to be sent to other network elements. If the gateway determines that it needs to be sent, the process proceeds to step 416; otherwise, returns to continue to determine. Once the ignition is successful, the current state of the ignition component of the car is set to the start state. When the state of the ignition component changes, the vehicle ignition component of the car ignition component sends the current new state to the gateway (the gateway then reports to the user that the ignition has been initiated). The success message, at the same time the gateway then determines which functional components need to be sent to the new status report, such as to the car oil spill monitoring function, etc.; If the ignition fails, the state of the ignition component of the car remains unactivated. The current status will also be sent to the gateway, which in turn determines which functional components to send the status report to. If the gateway chooses to return the message of the failed ignition to the control terminal, the user may initiate the message after receiving the message that the ignition failed. Ignition operation, the procedure is the same as above.

Step 416: The in-vehicle gateway sends an instruction to other functional modules.

Figure 5 is a flow chart showing still another embodiment of the method according to the present invention for detecting and notifying the owner of a vehicle oil leak. As shown in Figure 5, the method includes the following steps:

Step 502: The component control module monitors the component.

The car oil leak detection component detects the current gasoline scale value at several points in the fuel tank wall. The more points the detected data are, the more accurate the results are. The average of the tank scales read at these points is the current scale value of the gasoline in the current tank.

Step 504: Monitor whether the state of the component is abnormal. When an abnormality is detected, go to step 506; if no abnormality is detected, continue monitoring.

When the vehicle oil leakage monitoring component receives the report that the car sent from the gateway is at a standstill, the gasoline monitoring component records the gasoline scale value in the current mailbox, and starts a timer to read the scale value of the oil amount at this time, which will be real-time. The scale value read is subtracted from the initial scale value recorded in the previous tank. If the difference is within the threshold, it means that there is no oil leakage at this time, and if it is greater than the threshold value, it indicates that there is an oil leakage event. If the difference is greater than the threshold value for a specified number of times, for example, if the difference is greater than the threshold value for three consecutive times in the timer detection, the gasoline monitoring component sends the event command to the component control module in the vehicle network element; the vehicle oil leakage monitoring component After receiving a report from the gateway that the car is in the startup state, when the car is stationary When entering the driving state, the gasoline monitoring component records the initial oil volume before driving and starts another timer to read the scale value of the oil amount at this time. The timer reads the current remaining amount of oil in real time and calculates the difference between the remaining amount of oil and the initial amount of oil, which is the actual amount of oil discharged. After that, the actual oil output is compared with the fuel consumption recorded in the vehicle fuel consumption recorder. If the actual oil output minus the actual fuel consumption recorded in the fuel consumption recorder is greater than the threshold value, it indicates that there is a leak at this time. An oil incident occurred. If the difference is greater than the threshold value, the result occurs in three consecutive timer detections, and the gasoline monitoring component sends the event command to the component control module in the vehicle network element.

Step 506: The component control module transmits the abnormality information to the wireless access module.

Step 508: Transfer the abnormal command information to the in-vehicle gateway.

The component control module controls the wireless access module to send the oil leakage event command to the vehicle network access module of the vehicle gateway through the wireless local area network communication mode; the vehicle network access module of the vehicle gateway is responsible for receiving the oil leakage event instruction and transmitting the instruction A data processing module for the in-vehicle gateway.

Step 510: The vehicle gateway processes the instructions as prompt texts that are easy for the user to understand.

The data processing module of the vehicle gateway translates the event instruction into a notification message that the remote control terminal can recognize, such as a prompt text that is easy for the user to understand, and sends the notification message to the wireless communication module of the vehicle gateway;

Step 512: Send an instruction to the user.

Here, the wireless communication module sends the received notification message to the control terminal in time, and can be notified to the control terminal by means of a short message or other means. In this way, the owner of the vehicle knows that his car is leaking oil and can handle it according to the message received by the control terminal.

The above is a further detailed description of the present invention in connection with the specific embodiments, and the specific embodiments of the present invention are not limited to the description. It is to be understood by those skilled in the art that the present invention may be practiced without departing from the spirit and scope of the invention.
