报告内容摘要：

Active safety control is an important approach to maintain stability of vehicle dynamics. Various active safety control methods, such as direct yaw moment control (DYC), active steering control (ASC), have been widely discussed in literature. One key characteristic of these existing active safety control methods is that tire friction forces or road conditions heavily influence the control effects. In this talk, inspired by the recent actuation technology of in-wheel motors, two active safety control design without relying on the tire friction forces will be presented. An active yaw stabilizer (AYS) and an active rollover preventer (ARP) are proposed for active yaw and roll motions control, respectively. The modeling of the novel AYS and ARP will be first introduced. Lyapunov based control design is applied to obtain the effective control laws. In addition, a new rollover index based on mass-center-position (MCP) is proposed to achieve continuously control of the vehicle roll motion. Co-simulation results between Matlab/Simulink and CarSim® will be presented. Comparisons with other active safety control methods will be discussed. The effectiveness of the proposed AYS and ARP design will be demonstrated through different simulations on low friction roads.
