The invention discloses a safe approaching area defining method for assisting and automatic driving, and belongs to the technical field of traffic safety. According to the method, psychological changes and driving behaviors of the driver in different driving scenes are considered together, the sensing threshold value of the driver for approaching or leaving the front vehicle is found, and then the minimum JND is obtained, namely, the change of the distance between the two vehicles in the process that the driver senses the relative speed is obtained. The vehicle distance when the vehicle is accelerated or decelerated is obtained through the distance between the front vehicle and the rear vehicle in the following process and the minimum perceptible difference, and then a deceleration algorithm and an acceleration algorithm of the vehicle are constructed. In the construction of a deceleration and acceleration algorithm of the vehicle, the relative speed between the vehicle and the front vehicle is considered, and the safe approaching area of the vehicle is determined. According to the invention, vehicle rear-end collision can be effectively prevented, the safety of personnel in the vehicle is improved, and traffic jam is improved. In addition, various conditions in a real driving scene are fully analyzed, and the availability of the method for determining the safe approaching area is remarkably improved.
本发明公开的一种用于辅助与自动驾驶的安全接近区域界定方法,属于交通安全技术领域。本发明将驾驶员在不同驾驶场景下的心理变化和驾驶行为一起考虑,找到驾驶员对前车接近或者远离的感知阈值,进而求出最小可觉差JND即驾驶员感知到相对速度的过程中两车间距变化。通过跟驰过程中前后车辆间的距离以及最小可觉差得到车辆采取加速或者减速时的车辆间距,进而构建车辆的减速算法和加速算法。在车辆的减速和加速算法的构建中考虑车辆与前车间的相对速度大小,确定车辆安全接近区域。本发明能够有效地防止车辆追尾,提升车内人员安全性,并且改善交通拥堵。此外本发明充分分析真实驾驶场景中的各种情况,显著提高安全接近区域确定方法的可用性。
