As shown in fig. 1, a vehicle controller flashing method according to a first embodiment of the present invention includes the following steps:
and S110, acquiring a voice signal.
The voice signal may refer to a signal formed by sound waves emitted by a person, and the voice signal may be collected by various sensors having a signal collecting function, such as a sound sensor. The embodiment does not limit the collection mode of the voice signal, for example, the collection is performed by a voice module in the flash device.
In this embodiment, the acquired voice signal is sent by the user and can be collected by a sound sensor in the voice module.
Optionally, before acquiring the voice signal, the method further includes: acquiring a flash file selected by an upper computer or a display screen; acquiring a flash instruction corresponding to the flash file through a voice module; storing the corresponding relation between the flash file and the flash instruction to an instruction set; wherein one of the flash files corresponds to one of the vehicle controllers.
The flash file may be a binary file generated according to a host computer programming language for controlling the flash of the ECU. The flash file can be acquired through the software of the upper computer and also can be acquired through the display screen, and the display screen can be integrated on the flash equipment. Wherein the memory of the vehicle contains the flash file required by each ECU already stored in the vehicle ECU. The user can select any flash file through the display screen to establish the instruction set. The Flash file can be used for flashing the vehicle ECU, specifically, the Flash file can be written into a memory chip (Flash) of the ECU according to a certain Flash process, and then the ECU is flashed according to the Flash file. Wherein, Flash can be regarded as a memory of the ECU for storing data information of the Flash file written in the ECU.
The flash flow includes a pre-programming phase, a programming phase, and a post-programming phase.
The specific steps of the pre-programming stage are as follows: first reading ECU identification information (i.e., information identifying an ECU); then opening an extended session (session), which can be used to maintain the read ECU identification information; then disabling Diagnostic Trouble Code (DTC) storage, wherein if a car, i.e., vehicle, is detected as malfunctioning, the transmitter control system will store the DTC in memory for detection, and no Trouble diagnosis is needed during the pre-programming phase, thus disabling the DTC; finally, a program session is initiated, while non-diagnostic communications are disabled for normal completion of the handoff session.
The programming stage comprises the following specific steps: firstly, unlocking an ECU to be flashed; then erasing the original flash program in the ECU, so as to facilitate the input of a subsequent new program; and finally, downloading related application software, detecting an application program in the software, and programming.

The voice signal acquisition unit can be used for acquiring voice signals sent by users. The signal processing unit may be configured to perform signal amplification, filtering, and other processing on the acquired voice signal, for example, the processing of the voice signal may be implemented by an amplifying circuit and a filtering circuit, which is not limited in this embodiment. The signal conversion unit can be used for converting the voice signal into the flash instruction, so that the corresponding relation between the flash instruction and the flash file can be conveniently established subsequently, and the ECU flash operation can be controlled by inputting the voice signal by a user. The specific technical means of conversion is not limited herein.

Where the data includes, but is not limited to, instruction sets and control information.

The steps of obtaining the instruction set by learning are as follows: firstly, voice signals used for constructing an instruction set can be obtained for multiple times through a voice module according to the number and the types of the vehicle ECUs, and are converted into voice instructions, namely, flash instructions, wherein each voice instruction can control one ECU to flash; then storing the corresponding relation between the obtained voice commands and the corresponding flash files into a command set; and finally, storing the established instruction set into the industrial control host for calling. The method for acquiring the instruction set is simple in operation, and if the subsequent ECU which needs to be added exists, the voice instruction corresponding to the flash file required by the ECU can be directly added into the instruction set without repeatedly acquiring the instruction set.
And S120, inquiring a predetermined instruction set, and determining control information corresponding to the voice signal.
The predetermined instruction set may be considered as an instruction set established in advance before the voice signal is acquired, and the step may perform query of the instruction set by calling the instruction set stored in the industrial control host to determine the control information corresponding to the voice signal.
The control information may refer to information for controlling the ECU to write by flash, for example, the control information may be a flash file and corresponding ECU identification information, or may be information for identifying the flash file and corresponding ECU.
Illustratively, the specific steps of determining the control information corresponding to the voice signal are as follows: firstly, acquiring a voice signal and converting the voice signal into a voice instruction; then, calling an instruction set stored in the industrial control host, comparing the acquired voice instruction with the instruction set, and judging whether the voice instruction is valid (namely whether the voice instruction exists in the instruction set, namely whether the corresponding voice instruction can be found in the instruction set); and finally, if the voice instruction is valid, determining the control information corresponding to the voice instruction according to the instruction set, and if the voice instruction is invalid, not performing any processing and waiting for the next voice instruction. In this embodiment, the comparison between the voice command and the command set, and the data processing operations such as determination and storage of the control information are performed in the industrial personal computer.
And S130, sending the control information to the corresponding vehicle controller.
In this embodiment, the control information may be transmitted through a bus in the industrial personal computer, for example, the control information is sent to the corresponding vehicle Controller through a Controller Area Network (CAN) bus.
