Description

technical field [0001] The invention relates to a vehicle-mounted data acquisition system based on an embedded PC applied in the field of automobiles. Background technique [0002] The on-board data acquisition system is used to collect and record vehicle operation data during vehicle development for analysis and design improvement. Currently, vehicles using new powertrains, such as hybrid vehicles and fuel cell vehicles, are becoming a research and development hotspot. These new cars are characterized by more components and controllers, a bus communication structure, and more operating parameters. The power system of new cars has become more complex, and more sensors need to be installed during the development process, and more testing instruments are used to test the whole vehicle. Therefore, the on-board data acquisition system needs to have more powerful data acquisition capabilities and device interface capabilities, and at the same time have the characteristics of sm...
