Embodiment 1

[0054] The embodiment of the present invention provides a shortcut for remote software program update for a car in a wireless network environment. A network server is set for each vehicle-mounted remote control terminal. The network server, as the output end of the entire system, is responsible for transmitting and writing data to the vehicle-mounted remote control terminal through the wireless network. The network server uniformly distributes the target files to all registered vehicle-mounted remote control terminals, and at the same time informs the user terminal of the car by means of information transmission. Have a more intelligent feeling in the process of using the car.

[0055] A schematic diagram of a method for remotely updating a software program in a car provided by this embodiment is as follows: figure 1 As shown, the specific processing flow is as follows figure 2 It includes the following processing steps:

[0056] Step S210, the vehicle-mounted remote contr...

Embodiment 3

[0082] This embodiment provides a system for remotely updating a software program in an automobile, the specific structure of which is as follows image 3 As shown, it includes: a network server 31, a mobile terminal 32 and a vehicle-mounted remote control terminal 33;

[0083] The network server 31 is used to send the identification of the electronic control unit ECU and the software program of the latest version to the vehicle-mounted remote control terminal in the automobile through the wireless communication network;

[0084] The mobile terminal 32 is used to send a software program update notification message carrying the identifier of the ECU to the vehicle-mounted remote control terminal;

[0085] The vehicle-mounted remote control terminal 33 is used to associate and store the received identifier of the ECU with the software program of the latest version, and after receiving the software program update notification message carrying the identifier of the ECU sent by the...

Abstract

The embodiment of the invention provides a method and system for remotely updating a software program in an automobile. The method mainly includes the steps that a network server transmits ECU identification and a software program of the latest version to an automobile-mounted remote control terminal in the automobile through a wireless communication network, and the automobile-mounted remote control terminal stores the received ECU identification and the software program of the latest version in an associating mode; after receiving a software program updating notification message carrying the ECU identification and transmitted by a mobile terminal, the automobile-mounted remote control terminal transmits the software program of the latest version to an ECU, wherein the software program of the latest version is stored in the associating mode, and the ECU installs the software program of the latest version for updating. According to the method and system for remotely updating the software program in the automobile, the mobile terminal of a user can uniformly control the automobile-mounted remote control terminal and the ECU to update and install a target file, the software program work of the ECU can be flashed remotely, the program flashing work of the ECU is intelligentized, and the operation cost of all ECUs is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method and system for remotely updating a software program in an automobile. Background technique [0002] Due to the popularity of automotive electronics, the number of electronic devices in the car has increased dramatically. There are usually multiple ECUs (Electronic Control Unit, electronic control unit) on the car. Each ECU needs to run corresponding software programs, and these software programs need to be updated. . [0003] A method for updating the software program on the car in the prior art is: when the car software needs to be updated, the user needs to go to the car maintenance site or the maintenance personnel to come to the door, and the engineer takes a notebook, a car, To flash the program with one car, that is, to update the software program of the ECU on the car. [0004] The shortcomings of the method for updating the software program on the...
