Problems solved by technology
At the same time, since the past 10 years, the business of domestic automobile diagnosis and maintenance and controller program upgrade has also been fully popularized. The combination of automobiles and the Internet has introduced the concept of "iteration", and the demand for remote upgrades of automobiles has greatly increased, while the traditional CAN bus has been affected. Due to bandwidth limitations, the software update speed is slow, ranging from a few minutes to more than an hour. This is a challenge for stability and reliability, as well as for the battery power supply of the vehicle, and for user experience.

Embodiment Construction
[0065] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0066] The vehicle controller parallel refreshing method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the configuration tool 102 communicates with the refreshing terminal 104 through the network, and the refreshing terminal 104 communicates with the forwarding engine 106 installed on the vehicle through the network. Specifically, the user needs to load the refresh file into the configuration tool 102, so that the configuration tool 102 groups the refresh files according to the bus type of each controller to...

The invention relates to the field of vehicles, in particular to a vehicle controller parallel refreshing method and device, computer equipment and a storage medium. The method comprises the following steps: receiving a refreshing file of each controller to be refreshed of a vehicle; grouping the refreshing files according to the bus type of each controller to be refreshed; configuring to-be-refreshed controllers corresponding to the refresh files of different groups to be in a parallel refresh mode, and configuring to-be-refreshed controllers corresponding to the refresh files in each group to be in a sequential refresh mode; and sending the configured refresh file to a refresh terminal, the configured refresh file being used for indicating the refresh terminal to perform parallel refresh on each to-be-refreshed controller of the vehicle according to the configured refresh file. By adopting the method, the refreshing efficiency can be improved.
Description
technical field [0001] The present application relates to the technical field of intelligent vehicles, in particular to a parallel refresh method, device, computer equipment and storage medium for vehicle controllers. Background technique [0002] The modern automobile industry is developing rapidly. Since the 1990s, a large number of CAN bus communication has been adopted, and until now the replacement of automotive Ethernet and CAN FD, the bus technology is also developing rapidly, and the transmission rate is also increasing rapidly. At the same time, since the past 10 years, the business of domestic automobile diagnosis and maintenance and controller program upgrade has also been fully popularized. The combination of automobiles and the Internet has introduced the concept of "iteration", and the demand for remote upgrades of automobiles has greatly increased, while the traditional CAN bus has been affected. Due to the limitation of bandwidth, the speed of software update...
