The invention relates to the technical field of automobile electronics, and discloses a cruise control method and system of a vehicle and vehicle terminal equipment. The method comprises the following steps: acquiring road condition gradient information and a vehicle swing angle of a vehicle in a driving process; dividing a driving road section of the vehicle based on the road condition gradient information, and determining a target cruise speed of the vehicle in a road section switching process; correcting the road condition gradient information by using the vehicle swing angle, determining target road condition gradient information, and storing the target road condition gradient information; and controlling the vehicle to run according to the target road condition gradient information and the target cruise vehicle speed. According to the technical scheme, the gear and the speed of the vehicle are automatically changed according to the future road condition information in the cruising process, so that the vehicle can run according to the optimal state, the situation that stable running of the vehicle is affected due to excessive switching of the vehicle is prevented, meanwhile, the bad running state of the vehicle is avoided, oil consumption is reduced, and the oil saving effect is achieved.

    本发明涉及汽车电子技术领域,公开了一种车辆的巡航控制方法、系统及车辆终端设备。其中,该方法包括:获取车辆在行驶过程中的路况坡度信息以及车辆摆动角度;基于路况坡度信息对车辆的行驶路段进行划分,确定车辆在路段切换过程中的目标巡航车速;利用车辆摆动角度对路况坡度信息进行修正,确定目标路况坡度信息,并存储目标路况坡度信息;控制车辆按照目标路况坡度信息以及目标巡航车速进行行驶。通过实施本发明技术方案,在巡航中自动根据未来路况信息进行车辆档位、车速的改变,使得车辆能够按照最优状态进行行驶,防止车辆切换过猛而影响车辆的平稳行驶,同时避免车辆的不良运行状态,减少了油耗,达到了节油的效果。
