Problems solved by technology
[0004] The development method of MATLAB+dSPACE is costly and suitable for the initial technology development stage. For the subsequent trial production and calibration stages of small batches of vehicles, due to the large number of vehicles, if each vehicle is installed with a Micro Auto Box rapid prototyping system, the cost will be high
Secondly, the Micro Auto Box rapid prototyping system is large in size and needs to be placed in the trunk of the vehicle. For the vehicle, it is necessary to change the design of the wiring harness and other design, which requires a large change

The invention discloses a design method, device, equipment and storage medium of an automobile gateway, which generates a configurable gateway routing table, a vehicle bus database, and a function function file according to an automobile network function specification file; and combines the configurable gateway routing table and the vehicle bus database Import the gateway configuration software to generate the gateway configuration file; download the gateway configuration file and the function function file to the gateway hardware, so that the gateway hardware executes the software function according to the gateway configuration file and the function function file. The technical solution of this embodiment reduces the development cost, and does not need to change the design of the wiring harness of the whole vehicle, and can be mounted on a small-batch trial vehicle.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of vehicle network topology, and in particular to a design method, device, device and storage medium of a vehicle gateway. Background technique [0002] Due to the increasing number of controllers on the car and the more complex functions, different stages of car development may involve unexpected changes in the gateway communication protocol. [0003] In the process of automobile development, automobile manufacturers generally use the model-based development process, combined with rapid prototyping products focused on the development of automobile controllers, to develop a development platform suitable for the replacement of their own automobile gateway controllers. For example, the development tool uses the Micro Auto Box rapid prototyping system development kit, combined with MATLAB software to build the gateway development platform. [0004] The development method of MATLAB+dSPACE ...
