Abstract

The invention discloses a method and a device for monitoring a vehicle state and a driving behavior. The method comprises the following steps that first data which is transmitted by a CAN bus connected with at least one set of acquisition equipment and corresponds to a set part state of a target vehicle is obtained; the first data is acquired by the at least one set of acquisition equipment; second data output by a switching amount output line of at least one set of switching equipment on the target vehicle is obtained; driving state data which is generated by a satellite positioning vehicular terminal and corresponds to the target vehicle is obtained; the first data, the second data and/or the driving state data are comprehensively analyzed according to a set algorithm, and target vehicle state information and driving behavior information are generated according to an analysis result. The technical scheme provided by the embodiment of the invention can comprehensively consider many vehicle part state parameters so as to realize identification of the vehicle state and the driving behavior; a communication module and a positioning module of the satellite positioning vehicular terminal are shared by using a splitting type structure, so that the hardware cost is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle control, and in particular to a method and device for monitoring vehicle state and driving behavior. Background technique [0002] Vehicle status (such as vehicle speed, door closing status, fuel consumption, temperature inside the vehicle, etc.) and the driving behavior of the vehicle driver (such as braking behavior, neutral coasting, etc.) play a crucial role in the safe driving of the vehicle. If relying solely on manpower to monitor vehicle status or driving behavior, it is not only time-consuming and labor-intensive, but also lacks real-time monitoring. [0003] In the prior art, the monitoring process of the vehicle monitoring system is usually: obtain the position state parameters of the vehicle through GPS (Global Positioning System, Global Positioning System); obtain the door state parameters collected by the door switch value; Analytics to enable monitoring of veh...
