Analysis of vehicle stability control based on line control active steering system

Abstract

In the current society, due to the rapid development of science and technology, the embodiment in the automobile field is more prominent. The car has changed from the initial manual transmission to the current automatic transmission, and at the same time, under the development of these technologies, the safety factor of the vehicle has also been greatly improved. Especially in the turning stage of the vehicle, in order to ensure the stability of the vehicle when bending, the driver needs to control the direction of the speed to stabilize the vehicle, to avoid the occurrence of safety accidents. Vehicle steering system is a convenient way for the driver to control the vehicle driving according to the driving intention, and the key subsystem to realize the stable vehicle driving (line-controlled steering technology). For the safety of vehicles, the emergence of line control system greatly improves the lightweight and intelligence of vehicles. Because the mechanical connection between the steering wheel and the steering assembly is cancelled, the steering wheel cannot receive timely feedback from the road information in some aspects. Therefore, the driver is required to form a sense of road on the road surface when driving the vehicle. The line control steering technology controls the vehicle steering through the line control signal, improves the steering sensitivity and low speed stability, and provides excellent hardware and intelligent ECU (electrical control unit), which is the basis of automatic vehicle steering. Compared with the traditional steering system, the wire-control steering system can not only control the stability of the vehicle, but also make the driver feel comfortable while driving the vehicle. After analyzing the stability parameters of the vehicle during the vehicle steering, a vehicle stability control scheme based on the linear active steering system is developed.
