“…Moon and Yi et al [11,12], by analyzing the driver's behavior, proposed a confusion matrix method to adjust the control parameters and designed an integrated ACC/CA system to ensure the safe driving of the vehicle. Seyed Mehdi et al [13] proposed a novel reference signal for the ACC system, which reduced the time difference between the initial state and stable state, and improved comfort while ensuring safety. Based on reinforcement learning theory, Das et al [14] improved traffic efficiency by controlling the parameters of the safe inter-distance model.…”

To ensure lateral stability during the cruising of a differential steering vehicle (DSV), this paper presents a curving adaptive cruise control (ACC) system coordinated with a differential steering control (DSC) system, which considers both longitudinal cruising capability and lateral stability on curved roads. Firstly, a DSV dynamics model is developed and a control strategy architecture for a curving ACC system is designed. Then, the car-following control strategy for the curving ACC system is designed based on the fuzzy model predictive control (FMPC) algorithm. The strategy aims to improve the economy and balances car following, safety, comfort and economy. Moreover, fuzzy logic rules are designed to update the weight coefficients of the performance indicators in real time. Finally, the lateral stability controller is designed based on the preview algorithm and the sliding mode control (SMC) algorithm. The simulation results show that the lateral stability of the DSV during the curving cruise is realized via the control of the differential drive torque of the two front wheels. The proposed FMPC controller and SMC controller based on the preview control algorithm satisfy the performance in terms of vehicle following and lateral stable driving in the process of cruising.

“…Existing work on cruise control includes several methodologies such as optimal, robust, and LPV control (Gáspár et al, 2017;Kayacan, 2017;Németh and Gáspár, 2011;Öncü et al, 2014;Rajamani and Zhu, 2002). Some work has been linked to the comfort objective (Du et al, 2018;Mohtavipour and Mollajafari, 2021;Schmied et al, 2016).…”

In this paper, we present an LMI-based approach for comfort-oriented cruise control of an autonomous vehicle. First, vehicle longitudinal dynamics and a corresponding parameter-dependent state-space representation are explained and discussed. An LMI-based polytopic LQR controller is then designed for the vehicle speed to track the reference value in the presence of noise and disturbances, where the scheduling parameters are functions of the vehicle mass and the speed itself. An appropriate disturbance force compensation term is also included in the designed controller to provide a smoother response. Then we detail how the reference speed is calculated online, using polynomial functions of the given desired comfort level (quantified by the vertical acceleration absorbed by the human body) and of the road type characterized by road roughness. Finally, time-domain simulations illustrate the method’s effectiveness.
