Simulation debugging system and method for vehicle information system

Abstract

The invention discloses a simulation debugging system for a vehicle information system. The system comprises a VHAL data simulation module which is used for carrying out data interaction with an Android vehicle hardware abstraction layer through a VHAL data forwarding client and a VHAL data forwarding server; a soft serial port data simulation module which is used for performing data interaction with the serial port equipment node or the Android vehicle hardware abstraction layer through the serial port equipment node data forwarding client and the serial port equipment node data forwarding server; a hard serial port data simulation module which is used for performing data interaction with the in-vehicle machine micro-control unit or an in-vehicle machine system-on-chip through the USB serial port equipment driving module and the USB-to-serial port equipment; and a CAN message simulation module which is used for carrying out data interaction with the vehicle machine micro-control unit through the CAN box driving module and the CAN box. According to the embodiment of the invention, a complete vehicle hardware environment does not need to be built, and simulation debugging of the information channel between any nodes can be realized.

Description

Technical field [0001] The present invention relates to the field of vehicle control calculations, and more particularly to an analog debugging system and method of a vehicle information system. Background technique [0002] With the rapid development of the vehicle industry, the vehicle system is increasingly complex. In order to achieve efficient control of various electronic devices in the vehicle, it is necessary to simulate the vehicle information link. like figure 1 As shown, a complete vehicle information link is routing the automotive ECU (Electronic Control Unit, electronic control unit), a vehicle MCU (Micro ControllerUnit, microcontrol unit), a node such as a vehicle SOC (SYSTEM ON A CHIP, system-level chip) Composition, different communication protocols are used in different communication protocols between individual nodes. [0003] In the prior art, when developing a single module of the vehicle information link, a complete vehicle hardware environment must be built,...
