In some embodiments of the present disclosure, the method shown in fig. 1 may be applied to an upgrade management device of a vehicle, where the upgrade management device may be a main control device in the vehicle, and may be, for example, a driving computer.

As shown in fig. 1, the software upgrading method may include the following steps.

And S110, receiving software upgrading data corresponding to the target software.

Specifically, the target software is a software program to be upgraded of the device to be upgraded, and the specific implementation function of the target software is not limited herein, and for example, the target software may include interactive software, such as navigation software or audio playing software; the target software may also include automatic driving class control software, such as automatic parking garage software, automatic path planning software, or automatic collision warning software.

Specifically, the software upgrade data is a software upgrade package required in the process of updating the target software from the low version to the high version, and through the software upgrade data, the target software can realize software upgrade so as to achieve functions of improving performance or repairing bugs and the like.

Specifically, the software upgrade data sent by the server may be received using wireless communication technology. The software upgrade data on the server may be uploaded to the server by a developer of the target software or a manufacturer of the device vehicle to be upgraded, which is not limited herein.

And S120, determining equipment to be upgraded corresponding to the target software.

Specifically, a vehicle to be upgraded generally includes a plurality of area control devices, and software installed in different area control devices is different. Therefore, it is necessary to determine the area control device to which the target software belongs from the plurality of area control devices, and the area control device to which the target software belongs is the device to be upgraded of the device to be upgraded corresponding to the target software. The specific determination mode of the device to be upgraded can be set by a person skilled in the art according to the actual situation, and is not limited herein.

Specifically, the device to be upgraded may be one control node in the vehicle other than the upgrade management device. When the device to be upgraded supports Direct Memory Access (DMA), the device to be upgraded may include a DMA controller and a secondary storage. The specific detection mode of whether the device to be upgraded supports DMA may be set by a person skilled in the art according to an actual situation, and is not limited herein.

Optionally, detecting whether the device to be upgraded supports a direct memory access technology may include: and inquiring the DMA zone bit in the parameter information of the equipment to be upgraded, and detecting whether the equipment to be upgraded supports DMA according to the DMA zone bit. For example, when the DMA flag bit is 1, it may be determined that the device to be upgraded supports DMA; when the DMA flag bit is 0, the device to be upgraded is determined not to support DMA.

Optionally, detecting whether the device to be upgraded supports the direct memory access technology may include: and inquiring a statistical table of the DMA supporting area control device to detect whether the device to be upgraded supports DMA. For example, when the device to be upgraded is recorded in the statistical table of the device for controlling the DMA area, it may be determined that the device to be upgraded supports DMA; and when the device to be upgraded is not recorded in the statistical table of the device for controlling the DMA area, determining that the device to be upgraded does not support DMA.

Specifically, the target flush address is used to determine the specific location of the secondary memory to which the software upgrade data needs to be written. The obtaining manner of the target write address may be set by a person skilled in the art according to actual conditions, and is not limited herein.

Optionally, the obtaining of the target write address corresponding to the target software may include: and sending an address request aiming at the target software to the equipment to be upgraded so that the equipment to be upgraded feeds back a target flash address corresponding to the target software. Therefore, the target flash address corresponding to the target software can be dynamically acquired, and even after the equipment to be upgraded corresponding to the target software is changed due to faults and the like, the target flash address corresponding to the target software can be accurately determined.

Optionally, determining the target write address corresponding to the target software may further include: and inquiring an association relation table among the software, the area control equipment and the address, and determining a target flash address corresponding to the target software. Therefore, the target flash address corresponding to the target software can be quickly determined.

Specifically, the target flash address includes a memory address of the secondary memory corresponding to the target software and a starting write address of the software upgrade data in the secondary memory. The software upgrading package corresponding to the same target software can be divided into a plurality of pieces of software upgrading data, the memory addresses of the secondary memories corresponding to the software upgrading data are the same, but the initial writing addresses corresponding to the software upgrading data of different blocks are dynamically updated, that is, after the software upgrading data of this time is written into the secondary memories, the next new software upgrading data is written into the same secondary memories, but the initial writing addresses are the addresses behind the written positions of the software upgrading data of this time.

And S140, sending the data to be refreshed to the equipment to be upgraded.

The data to be flashed comprises a target flashing address and software upgrading data.

Specifically, the data to be flashed may be sent to the device to be upgraded over the bus. The bus may include one of a Controller Area Network CAN (CAN) bus, a FlexRay bus, an Ethernet (Ethernet) bus, a Local Interconnect Network (LIN) bus, and a Serial Peripheral Interface (SPI) bus.

Optionally, before sending the data to be refreshed to the device to be upgraded, a target bus corresponding to the device to be upgraded is determined. The obtaining mode of the target bus corresponding to the device to be upgraded may be set by a person skilled in the art according to an actual situation, and is not limited herein.

Optionally, the target bus corresponding to the device to be upgraded may be determined by querying the area control device-bus correspondence table.

Specifically, the specific implementation of sending the data to be flashed to the device to be upgraded may be set by a person skilled in the art according to an actual situation, and is not limited herein.

Optionally, before sending the data to be refreshed to the device to be upgraded, the method further includes: sending an upgrading request aiming at target software to equipment to be upgraded so that the equipment to be upgraded feeds back data transmission parameters of the equipment to be upgraded; sending the data to be flashed to the device to be upgraded comprises: and sending the data to be refreshed to the equipment to be upgraded according to the data transmission parameters.

The data transmission parameters include a maximum transmission unit size and a remaining buffer size. The maximum transmission unit size is the size of the maximum data packet which can be passed by the bus corresponding to the equipment to be upgraded; the size of the residual cache region is the size of the residual cache region in the cache region of the equipment to be upgraded.

Optionally, sending the data to be refreshed to the device to be upgraded according to the data transmission parameter includes:

and segmenting the data to be refreshed into a plurality of data packets to be refreshed, and sending the data packets to be refreshed to the equipment to be upgraded through the bus.

The size of the data packet to be refreshed is smaller than or equal to the size of the maximum transmission unit, and the size of the software upgrading data is smaller than or equal to the size of the residual cache area. Optionally, the flash data may further include a size of the remaining cache region, so that the device to be upgraded determines a relationship between the size of the software upgrade data and the size of the remaining cache region.

It can be understood that, when the size of the software upgrade package corresponding to the target software is larger than the size of the remaining cache region, the software upgrade package is divided into a plurality of pieces of software upgrade data, and S110-S140 are repeatedly executed until the software upgrade package is completely transmitted to the first external storage device.

It is also understood that the zone control devices corresponding to different software may be different, the remaining buffer sizes of the different zone control devices may be different, and the maximum transmission unit sizes of the buses corresponding to the different zone control devices may also be different. Therefore, when the target software to be upgraded is changed, the device to be upgraded corresponding to the target software may also be changed correspondingly. And the data to be refreshed is segmented into a plurality of data packets to be refreshed and then transmitted according to the maximum transmission unit size corresponding to the equipment to be upgraded and the size of the residual cache region, so that the probability of data transmission errors can be reduced, and a foundation is laid for accurately transmitting data to different equipment to be upgraded.

Specifically, under the condition that it is detected that the device to be upgraded corresponding to the target software supports the direct memory access technology, the data to be refreshed can be sent to the device to be upgraded, so that the device to be upgraded writes the software upgrading data into the target refreshing address by using the DMA.

It will be appreciated that since DMA technology allows data to be read and written directly between the zone control device and the memory, neither CPU intervention is required nor through the CPU. Therefore, after the device to be upgraded supporting the DMA receives the flash data, the software upgrading data can be directly written into the target address by bypassing the CPU. Therefore, in the process of writing the software upgrading data into the target address, the CPU can perform other work, the work delay of the CPU is avoided, and the work efficiency of the CPU is improved.

The software upgrading method of the embodiment of the disclosure can receive software upgrading data corresponding to target software; determining equipment to be upgraded corresponding to target software; under the condition that the device to be upgraded supports the direct memory access technology, acquiring a target flash address corresponding to target software; and sending the data to be refreshed to the equipment to be upgraded, wherein the data to be refreshed comprises a target refresh address and software upgrading data, so that the equipment to be upgraded adopts a direct memory access technology to write the software upgrading data into the target refresh address. Therefore, the software upgrading data can bypass the CPU and can be directly written into the target writing address, namely the writing process of the software upgrading data does not occupy CPU resources, the saved CPU resources can be used for carrying out other operations, and the efficiency of the CPU is improved.

In another embodiment of the present disclosure, optionally, in a case that it is detected that the device to be upgraded does not support the direct memory access technology, the software upgrade data is sent to the device to be upgraded.

Specifically, under the condition that it is detected that the device to be upgraded corresponding to the target software does not support the direct memory access technology, the software upgrading data can be sent to the device to be upgraded, so that the CPU of the device to be upgraded writes the software upgrading data into the target flash address of the secondary memory of the device to be upgraded based on the conventional access technology. Therefore, whether the equipment to be upgraded supports the DMA or not, the software upgrading data can be written into the target flash address, and the upgrading of the target software is completed.

For example, the preset speed value may be 0 or 20Km/h or less.

It can be understood that when the vehicle speed is the preset speed value, the vehicle is indicated to be in a stable driving state at present, and is not in a state with a high risk coefficient, such as sudden braking, sharp turning, uphill slope, or downhill slope, and the like, and the software is upgraded when the vehicle is in the stable state, so that the influence of the software upgrading process on the driving safety can be avoided.

When the residual battery capacity is greater than or equal to the preset capacity threshold, the residual battery capacity is large, and although part of the capacity can be consumed in the software upgrading process, the demand of the normal operation of the vehicle on the capacity can be met.

When the ignition switch control terminal is in a closed state, the vehicle is indicated to be in a state of not being started currently, and software upgrading is carried out at the moment, so that the situation that the driving safety is influenced in the software upgrading process can be avoided.

Therefore, under the condition that the vehicle to which the equipment to be upgraded belongs meets the software upgrading condition, the data to be refreshed is sent to the equipment to be upgraded so as to upgrade the target software, so that the target software can be upgraded when the vehicle is in a safe state, potential safety hazards are avoided, and the safety of people and vehicles is ensured.

Optionally, in the case that the vehicle does not satisfy the software upgrading condition, checking whether the vehicle satisfies the software upgrading condition again at preset time intervals until it is checked that the vehicle satisfies the software upgrading condition. Therefore, the upgrading data can be received in time when the vehicle is in a safe state, so that the target software can be upgraded as soon as possible.

Optionally, after sending the data to be refreshed to the device to be upgraded, the method may further include: receiving a receiving success notice sent by the equipment to be upgraded; in response to receiving the success notification, deleting the data to be flashed.

It can be understood that, when the reception success notification sent by the device to be upgraded is received, it indicates that the device to be upgraded has completely received the data to be refreshed, and at this time, deleting the data to be refreshed may increase the remaining space of the cache region of the upgrade management device, and the saved space of the cache region may be used to store other data.

In another embodiment of the disclosure, after the target software is determined to be upgraded, the vehicle to which the device to be upgraded belongs is controlled to restart.

Specifically, the specific implementation manner of determining whether the target software is upgraded or not may be set by a person skilled in the art according to actual situations, and is not limited herein.

Optionally, the vehicle may be controlled to restart after receiving an upgrade completion notification sent by the device to be upgraded.
