A closed-loop drive–vehicle–road–environment system (DVRES) model was established using Adams/Car and Matlab/Simulink. Dynamic responses of lateral tire forces based on tire–road side friction and road geometric characteristics are used to investigate vehicle side slip for geometric design safety estimation. The root mean square, the maximum values of lateral tire forces, comfort limit on curves and...
Direct yaw moment control (DYC) is the most potential chassis control method applied to electric vehicles (EV). In this paper, three stability controllers aimed at different targets based on sliding mode control (SMC) are designed: Yaw rate controller improves the vehicle stability by controlling the yaw rate; Slip angle controller is aimed at maintaining a minimum side slip angle; United controller...
Dynamic tracing and trace replay are two main functions in vehicle monitoring system of GIS. Based on the idea of line-to-point set, "point-to-point" road matching algorithm and "Trace interpolation" trace replay algorithm are designed and implemented. The main idea of "Point-to-point" is that the road will be separated into a series of discrete set points, and then got...
Improving the performance of a incident detection system was essential to minimize the effect of incidents. A new method of incident detection was brought forward in this paper based on an in-car terminal which consisted of GPS module, GSM module and control module as well as some optional parts such as airbag sensors, mobile phone positioning system (MPPS) module, etc. When a driver or vehicle discovered...
