Abstract

The invention discloses a vehicle running information acquisition system and method using a dual-processor architecture. The system comprises a data acquisition unit, a temporary cache unit and a control unit which are connected one another, wherein the data acquisition unit is used for acquiring vehicle running information data in real time and sending the vehicle running information data to the temporary cache unit or the control unit; the temporary cache unit is used for receiving and storing the vehicle running information data acquired by the data acquisition unit in a system starting process and sending the stored data to the control unit after an operating system is started successfully; the control unit is used for receiving and processing the vehicle running information data sent from the data acquisition unit and the temporary cache unit. According to the system, two processors capable of communicating with each other are used, a data acquisition function is independent, a special controller is in charge of real-time data acquisition, the temporary cache unit is configured, and all the vehicle running information data are acquired when the system is started and the controller has other inserted tasks.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a system and method for collecting vehicle operation information with a dual-processor architecture. Background technique [0002] The vehicle operation information collection system collects various effective signal data generated during vehicle operation and stores them locally, or sends them back to the service center through a wireless network for vehicle operation data analysis or vehicle operation status monitoring. [0003] Since the vehicle operating environment often changes, the real-time data acquisition system not only needs to have a good operating state under harsh working conditions, but also needs to ensure the timeliness and system reliability of data acquisition in emergencies. [0004] Usually, there will be problems of data leakage during the power-on and start-up process of the acquisition system, such as the following two situations: First, the vehicle real...
