Embodiment 1

[0033] The method embodiment provided in Embodiment 1 of the present application may be executed in a vehicle-mounted TBOX or other similar vehicle-mounted terminals. Take running on the car TBOX as an example, figure 1 It is a block diagram of the hardware structure of the vehicle-mounted TBOX of a method for updating the vehicle ECU firmware according to the embodiment of the present application, such as figure 1 As shown, the vehicle TBOX can include one or more ( figure 1 Only one is shown in the figure) processor 102 (processor 102 may include but not limited to processing devices such as microprocessor MCU or programmable logic device FPGA) and memory 104 for storing data. Optionally, the above-mentioned vehicle-mounted TBOX also Transmission means 106 for communication functions as well as input and output devices 108 may be included. Those of ordinary skill in the art can understand that, figure 1 The structure shown is only for illustration, and it does not limit t...

Embodiment 2

[0157] In this embodiment, a device for updating the firmware of the vehicle ECU is also provided, and the device is used to implement the above embodiments and preferred implementation modes, and what has been explained will not be repeated here. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0158] According to another embodiment of the present application, a device for updating vehicle ECU firmware is also provided, including:

[0159] An acquisition module, configured to acquire a firmware upgrade version of the vehicle electronic control unit ECU;

[0160] The simulation update module is used for simulating and updating the firmware of the vehicle ECU in the virtual machine according to the f...

Embodiment 3

[0172] According to another embodiment of the present application, a vehicle-mounted terminal is also provided, Figure 9 is a schematic structural diagram of a vehicle-mounted terminal according to another embodiment of the present application, such as Figure 9 As shown, the vehicle terminal 90 includes:

[0173] The ECU upgrade component 902 is used to request the firmware upgrade version of the vehicle control unit ECU to the cloud server, and download the firmware upgrade version of the ECU to the local storage;

[0174] The virtual security framework 904 is configured to simulate updating the firmware of the vehicle ECU according to the stored firmware upgrade version, and update the firmware of the vehicle ECU with the firmware upgrade version after the simulated update is successful.

[0175] By adopting the above solution, the problem that the vehicle cannot be started due to the failure of the firmware update of the ECU is avoided, and the problem in the related art...

Abstract

The invention provides a method and device for updating the ECU firmware of a vehicle. The method comprises the following steps that: 1, a to-be-updated firmware upgrading version of the ECU of the vehicle is obtained; the firmware of the ECU is simulated and upgraded to the firmware upgrading version in a virtual machine; and if simulation update succeeds, the firmware updating version is used for updating the firmware of the actual ECU of the vehicle. Therefore, the firmware updating success rate of the actual ECU is greatly improved, the problem that the vehicle cannot be started due to firmware updating failure of the ECU is avoided, and the problem that the success rate of an ECU firmware updating process in related technologies is low is solved.

Description

technical field [0001] The present application relates to but not limited to the field of vehicles, and specifically relates to a method and device for updating firmware of a vehicle ECU. Background technique [0002] At present, with the rapid development of the third-generation mobile communication system 3G and the fourth-generation mobile communication system 4G network, more and more vehicle-mounted terminal devices have integrated wireless communication modules, and such vehicle-mounted terminal products increasingly need to act as The control center for the entire in-vehicle network. The extension of this kind of control is getting bigger and bigger. In addition to the control of in-vehicle equipment, it also needs to be used as the network channel and control center of the passenger's mobile terminal in the car. This makes the application range of the vehicle terminal more and more extensive. Automobile manufacturers not only hope that the vehicle-mounted terminal ...
