HUMAN-CENTERED DESIGN OF A STOP-AND-GO VEHICLE CRUISE CONTROL
J. S. GU,S. YI,K. YI 한국자동차공학회 2006 International journal of automotive technology Vol.7 No.5
This paper presents design of a vehicle stop-and-go cruise control strategy based on analyzed results of the manual driving data. Human drivers driving characteristics have been investigated using vehicle driving data obtained from 100 participants on low speed urban traffic ways. The control algorithm has been designed to incorporate the driving characteristics of the human drivers and to achieve natural vehicle behavior of the controlled vehicle that would feel comfortable to the human driver under low speed stop-and-go driving conditions. Vehicle following characteristics of the cruise controlled vehicle have been investigated using a validated vehicle simulator and real driving radar sensor data.

Yi Kyongsu,Han Donghoon The Korean Society of Mechanical Engineers 2005 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.19 No.4
A vehicle cruise control strategy designed based on human drivers driving characteristics has been investigated. Human drivers driving patterns have been investigated using vehicle driving test data obtained from 125 participants. The control algorithm has been designed to incorporate the driving characteristics of the human drivers and to achieve natural vehicle behavior of the controlled vehicle that would feel comfortable to the human driver. Vehicle following characteristics of the cruise controlled vehicle have been investigated using real-world vehicle driving test data and a validated simulation package.

This paper presents development of the stop-and-go cruise control algorithm integrated with collision avoidance algorithm and test results obtained using an electric vehicle. Sliding control theory has been used to develop a vehicle speed and distance control algorithm. A vehicle desired velocity has been designed based on the vehicle speed and distance control algorithm. The collision avoidance control was designed based on time-to-collision and warning index. The motor control inputs have been directly derived from the sliding control law. The performance of the control algorithm has been investigated through computer simulation and vehicle tests using an electric vehicle.

In this paper, we propose a fuzzy control system using the acceleration profiles jerk consideration for autonomous in urban. Control system for the autonomous car has been developed a number of ways through the other studies. In this paper, the Autonomous vehicle receives object information such as the stop line, in order to perform the urban street. Receiving inter-vehicle information such as vehicle speed, acceleration, distance, TTC(Time to Collision) acceleration profile was constructed. And it was passing the acceleration value to the controller. In addition, in consideration of the driver"s tendency to driving comfort setting three modes (comfort, normal, sports) and it applied to the autonomous vehicle. Finally we implemented the ACC (adaptive cruise control) system, stop and go, stop line stop.

This proposes a design methodology for a full-range ACC (Adaptive Cruise Control) with collision avoidance braking. The control scheme is designed to control the vehicle so that it would feel natural to the human driver and passengers during normal safe driving situations, to completely avoid collision in vehicle following situations and to reduce the severity of collisions in unexpected emergency situations. Driving situations are determined by using a non-dimensional warning index and time-to-collision (TTC). The proposed control scheme can provide natural following performance similar to human manual driving in both high speed driving and low speed stop-and-go situations and can prevent vehicle collision in dangerous traffic situations such as severe braking of the preceding vehicle during a vehicle following situation.

This paper will address the basic requirements for realizing a stop and go cruise control system. Issues discussed comprise: functional, sensor and basic HMI requirements, primary characterization of naturalistic stop & go driving, and the basic approach of the transformation of situational knowledge in an elementary controller.
Design of 24 GHz Radar with Subspace-Based Digital Beam Forming for ACC Stop-and-Go System
Seong-Hee Jeong,Jun-Nam Oh,이쾌희 한국전자통신연구원 2010 ETRI Journal Vol.32 No.5
For an adaptive cruise control (ACC) stop-and-go system in automotive applications, three radar sensors are needed because two 24 GHz short range radars are used for object detection in an adjacent lane, and one 77 GHz long-range radar is used for object detection in the center lane. In this letter, we propose a single sensor-based 24 GHz radar with a detection capability of up to 150 m and ±30° for an ACC stop-and-go system. The developed radar is highly integrated with a high gain patch antenna, four channel receivers with GaAs RF ICs, and back-end processing board with subspace based digital beam forming algorithm.

Recently, ADAS such as SCC, CDM becomes hot issue and done in mass-production in luxury passenger cars. SCC control logic is divided in 2 parts; follow&distance control, acceleration control. CDM control logic is composed of collision warning and auto braking braking. Here develops vehicle acceleration control using vehicle speed and longitudinal acceleration sensor for SCC and CDM, and tests in vehicle state. The test results show that developed controller has good performance for SCC.

This paper presents a vehicle control algorithm for stop and go cruise control systems which makes the vehicle remain at a safe distance from a preceding vehicle according to the driver's preference, automatically slow down and come to a full stop behind a preceding vehicle. The control algorithm consists of speed and distance control algorithm and a combined throttle/brake control law. Throttle and brake actuators are controlled by the throttle/brake control law so that the vehicle acceleration tracks the desired acceleration designed based on the vehicle speed and distance control algorithm. A stepper motor and an electronic vacuum booster have been used for the throttle and brake actuators. The throttle and brake actuators have been tested and the actuator dynamics has been incorporated in simulation study. The uncertainties of vehicle model have been considered in the design of the control law. The effect of throttle/brake control has been investigated via simulations. The simulations were performed using a complete nonlinear vehicle model. The results indicate that the proposed control law can provide the stop and go cruise control system with a good distance and velocity tracking performance.
