The invention relates to an automobile intelligent self-adaptive cruise control system. The intelligent self-adaptive cruise control system comprises a camera module, a high-precision map and positioning module, a cruise control module and an execution module, and the cruise control module is connected with the high-precision map and positioning module, the camera module and the execution module; the camera module sends the obtained vehicle and lane line information to the high-precision map and the positioning module for matching the precise position of the vehicle in the high-precision map, and sends the lane and speed limit information in front of the vehicle to the cruise control module; the execution module comprises an electronic power-assisted steering system, a vehicle body stabilizing system, an engine control system and a gearbox control system, and the cruise control module calculates a vehicle deceleration moment and a target deceleration, sends the target deceleration to the vehicle body electronic stabilizing system, calculates a vehicle target torque and sends the vehicle target torque to the electronic power-assisted steering system. The road condition within a certain distance range in front is obtained in advance, so that a vehicle can smoothly pass through a curve at a safe speed.

    本发明涉及一种汽车智能自适应巡航控制系统,包括摄像头模块、高精度地图和定位模块、巡航控制模块、执行模块,巡航控制模块分别与高精度地图和定位模块、摄像头模块以及执行模块相连;摄像头模块将获得的车辆和车道线信息发送至高精度地图和定位模块用于匹配车辆在高精度地图中的精确位置,并将车辆前方车道及限速信息发给巡航控制模块;执行模块包括电子助力转向系统、车身稳定系统、发动机控制系统和变速箱控制系统,巡航控制模块计算出车辆减速时刻与目标减速度,并将目标减速度发送给车身电子稳定系统,计算出车辆目标转矩,发送给电子助力转向系统。本发明提前获得前方一定距离范围内的道路情况,使车辆能以安全车速顺利通过弯道。
