Abstract

The embodiment of the invention discloses a message simulation device, a message sending method and device and a computer storage medium, and belongs to the technical field of vehicle engineering. The message simulation device comprises an information processing device and a CAN module. The information processing equipment is in communication connection with the CAN module, and the information processing equipment is used for acquiring information of each control switch of a target automobile and analog quantity of each sensor of the target automobile sent by a terminal, processing the information of each control switch and the analog quantity of each sensor into a CAN message, and sending the CAN message to the CAN module; and the CAN module is used for sending the CAN message to the CAN bus of the target automobile after receiving the CAN message sent by the information processing equipment. According to the embodiment of the invention, a hardware switch corresponding to the control switch in the message simulation device can be canceled, and the message simulation device can be ensured to expand the CAN message, so that the message expansion cost is reduced, and the flexibility of the message simulation device is improved.

Description

Technical field [0001] The present application embodiments relate to the field of vehicle engineering technology, and in particular, to a packet simulation device, a message transmitting method, a device, and a computer storage medium. Background technique [0002] With the development of automobile technology, there are more and more functions of cars, and the information transfer between various electrical systems in the automotive is more frequent. Among them, there is a communication between the various electrical systems of the automobile, and the CAN bus has thousands of information flows at the time of the vehicle development, and the various electrical systems of the car. The complete communication network has not been formed, and the respective ECUs of the electrical system need to receive CAN messages from the bus during the test phase, so the packet simulation device of the CAN bus signal is born. [0003] Currently, the CAN bus signal is a pure hardware device, and th...
