Abstract

The invention discloses a vehicle stability evaluation method and a vehicle stability evaluation device. The vehicle stability evaluation method comprises the steps of: acquiring an acceleration eigenvalue of a vehicle owner obtained according to an acceleration eigenvalue of vehicle travel; acquiring a speed change threshold value obtained according to the acceleration eigenvalue of the vehicle owner; determining a speed change score value according to the speed change threshold value and the acceleration eigenvalue of the vehicle owner; and evaluating the stability of the vehicle accordingto the speed change score value. The vehicle stability evaluation method and the vehicle stability evaluation device provided by the invention can evaluate the stability of the vehicle by combining factors such as the driver and the vehicle more comprehensively.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a vehicle stability evaluation method and device. Background technique [0002] With the development of the Internet of Things, the analysis and application of the big data of the Internet of Vehicles is becoming more and more important for the driving of vehicles. Different cars will have different driving stability, and the same car will have different driving stability when driven by different people. Generally, an important indicator for vehicle stability evaluation is the change of travel speed. If the speed changes greatly, the vehicle is considered to be driving violently, and if the speed change is small, the vehicle is considered to be driving smoothly. [0003] However, the current main method for evaluating vehicle stability in the related art is still based on the absolute value of vehicle acceleration, which cannot well reflect the influence of factors ...
