The invention discloses a cruise control method with vehicle-mounted navigation information. The method comprises the following steps: acquiring navigation information from a vehicle navigation interface in real time through a CAN network; comparing the distance between a maneuvering point and a vehicle with a set threshold value; if the distance is smaller than the set threshold value and the vehicle is in a decelerating state at present, maintaining the current decelerating state; calculating the speed reduction amount in unit time, and broadcasting voice information for prompting speed reduction; if the vehicle is in the accelerator-stepping active acceleration state, stopping broadcasting the voice information, and waiting for the end of the state; and sending a deceleration instruction to an execution unit, and controlling the vehicle to change the vehicle speed according to the speed reduction amount in the unit time. The method can solve the problems that an existing self-adaptive cruise system can only control the speed of the vehicle according to the motion state of the front vehicle, cannot give consideration to other traffic conditions of a road, cannot decelerate and slowly pass through the maneuvering point such as an intersection in advance, and is prone to causing traffic risk.
本发明公开一种加入车载导航信息的巡航控制方法。所述方法包括:通过CAN网络从车机导航接口实时获取导航信息;比较机动点与本车的距离和设定阈值的大小;如果所述距离小于设定阈值,且本车当前处于减速状态,维持当前减速状态;计算单位时间的速度减少量,并广播提示减速的语音信息;如果处于踩油门主动加速状态,停止广播语音信息,等待所述状态结束;向执行单元发送减速指令,控制本车按照所述单位时间的速度减少量改变车速。本发明能够解决现有自适应巡航系统存在的只能根据前方车辆的运动状态进行本车速度控制,不能兼顾道路其他交通状况,在路口等机动点无法提前减速慢行通过,容易引发行车安全等问题。
