The invention discloses an automatic driving vehicle control method and system and a target speed calculation method. The control method comprises the steps of collecting visibility state data and road surface slippery degree state data of a vehicle driving road surface in real time; processing the road surface slippery degree state data, comparing the processed road surface slippery degree state data with a corresponding preset range to obtain the grade of the current road surface slippery degree, processing the visibility state data, and comparing the processed visibility state data with a corresponding preset range to obtain the grade of the current visibility; according to the grade of the current pavement slippery degree and the grade of the current visibility, matching a preset target speed in a database; and automatically reducing or increasing the speed of the vehicle in automatic driving to the target speed from the current speed so as to continue automatic driving. According to the automatic driving vehicle control method and system and the target speed calculation method provided by the invention, coupling processing is carried out on a multi-dimensional scene layer, a finite-state machine solution is adopted, and the deployment control efficiency is higher.
本发明公开了自动驾驶车辆控制方法、控制系统及目标速度的计算方法,控制方法包括:实时采集车辆行驶路面的能见度状态数据和路面湿滑程度状态数据;将路面湿滑程度状态数据处理后与相应的预设范围进行比较,以得到当前路面湿滑程度的等级,将能见度状态数据处理后与相应的预设范围进行比较,以得到当前能见度的等级;根据当前路面湿滑程度的等级和当前能见度的等级,匹配到数据库中预设的目标速度;自动驾驶中的所述车辆由当前车速自动降速或提速至所述目标速度,以便继续自动驾驶。本发明提供的自动驾驶车辆控制方法、控制系统及目标速度的计算方法对多维场景层进行耦合处理,采用有限状态机的解决方法,调配控制效率更迅速。
