Abstract

The objective of the present application is to provide a method and apparatus for processing real-time vehicle operating data, aiming at solving the technical problem that car owners couldn'"'"'t obtain real-time vehicle operating data to ensure safety via an existing vehicle-mounted system. The method comprises: obtaining real-time vehicle operating data from an electronic control unit of the vehicle via a vehicle bus; reading the real-time vehicle operating data from a serial port; determining whether there is data that needs to be answered in the real-time vehicle operating data and storing the real-time vehicle operating data into a data queue whose data need to be answered and a data queue whose data doesn'"'"'t need to be answered respectively after the determination; transmitting the real-time vehicle operating data to a background server, so that the background server can provide current vehicle with diagnostic message or service information. Compared with the prior art, the method provided in the embodiment of the present application can provide car owners with remote diagnosis or remote service conveniently, thereby reducing various costs of using cars.

Claims

1. A method for processing vehicle operating data, the method comprising:

via a vehicle bus, obtaining real-time vehicle operating data from an electronic control unit of a vehicle;

reading the real-time vehicle operating data from a serial port;

determining whether there is data that needs to be answered in the real-time vehicle operating data and storing the real-time vehicle operating data into a data queue whose data needs to be answered and a data queue whose data does not need to be answered respectively after the determination;

transmitting the real-time vehicle operating data to a background server, so that the background server provides the current vehicle with diagnostic message or service information,

wherein transmitting the real-time vehicle operating data to the background server includes;

transmitting the real-time vehicle operating data in the data queue whose data need to be answered to the background server and waiting for a response of the background server;

if the background server replies a response, transmitting the real-time vehicle operating data stored in a form of a data file to the background server;

if the background server replies after the real-time vehicle operating data is transmitted to the background server, eliminating the real-time vehicle operating data stored in the form of data files locally; and

if the background server does not reply a response after the real-time vehicle operating data in the form of data file is transmitted to the background server, and a continuous sending time exceeds a predetermined sending time, storing the real-time vehicle operating data locally.

2. The method according to claim 1, wherein after reading the real-time vehicle operating data via the serial port, the method comprises:

judging whether the vehicle is stopped according to the real-time vehicle operating data; and

if the judging indicates the vehicle as being stopped, controlling a vehicle operating data processing apparatus to turn into a sleep mode.

3. The method according to claim 2, further comprising:

judging whether a wireless fidelity device and a Bluetooth device are connected and whether a new single-chip computer program is performed after it is judged that the vehicle is stopped; and

if the wireless fidelity device and the Bluetooth device are not connected and there is no new single-chip computer program operating, turning the real-time vehicle operating data processing apparatus into the sleep mode.

4. The method according to claim 3, further comprising:

initializing the apparatus for processing real-time vehicle operating data in response to receiving a broadcasted wakeup signal.

5. The method according to claim 1, wherein before the real-time vehicle operating data is transmitted to the background server, the method further comprises:

judging whether a login into the background server is successful; and

if the login into the background server is successful, transmitting the real-time vehicle operating data to the background server.

6. The method according to claim 5, wherein transmitting the real-time vehicle operating data to the background server includes:

transmitting the real-time vehicle operating data in the data queue whose data does not need to be answered to the background server directly.

7. The method according to claim 5, wherein if the login into the background server fails, the method comprises storing the real-time vehicle operating data locally.

8. The method according to claim 1, further comprising:

storing data collected by a gravity sensor in the data queue whose data needs to be answered; and

storing position data collected by a Global Positioning System (GPS) module in the data queue whose data does not need to be answered,

wherein the data collected by the gravity sensor comprises emergency speed change data, vehicle accelerated speed data, and vibration alerting data.

9. The method according to claim 1, before obtaining the real-time vehicle operating data from the electronic control unit of the vehicle via the vehicle bus, the method further comprises:

initializing an apparatus for processing real-time vehicle operating data by booting a primary service application package (APK) directly or booting the primary service APK after it is installed.

10. An apparatus for processing vehicle operating data, comprising:

a first processor and a second processor, the second processor comprises a data reading module, a first judging module, and a first transmitting module, a fifth transmitting module, and a sixth transmitting module;

the first processor is configured for obtaining real-time vehicle operating data from an electronic control unit of the vehicle via a vehicle bus;

the data reading module is configured for reading real-time vehicle operating data obtained by the first processor from an serial port;

the first judging module is configured for determining whether there is data that needs to be answered in the real-time vehicle operating data and storing the classified real-time vehicle operating data into a data queue whose data need to be answered and a data queue whose data does not need to be answered respectively after determination;

the first transmitting module is configured for transmitting the real-time vehicle operating data to a background server, so that the background server can provide the current vehicle with diagnostic message or service information;

the fifth transmitting module configured for transmitting the real-time vehicle operating data in the data queue whose data need to be answered to the background server and waiting for a reply of the background server;

the sixth transmitting module configured for go on transmitting the real-time vehicle operating data stored in the form of data files to the background server if the background server replies a response;

the second processor further comprises a data storing module and a data eliminating module, wherein;

the data storing module is configured for storing the real-time vehicle operating data locally when the login into the background server does not reply a response after the real-time vehicle operating data in the form of a data file is transmitted to the background server, and a continuous sending time exceeds a predetermined sending time; and

the data eliminating module is configured for eliminating the real-time vehicle operating data stored locally in the form of data files locally if the background server replies after the real-time vehicle operating data stored in the form of data files is transmitted to the background server.

11. The apparatus according to claim 10, wherein the second processor comprises:
