The invention provides a speed-following early warning method and system for vehicle deviation and a vehicle. The method comprises the following steps: acquiring driving information; obtaining driving information; the driving information is analyzed, and whether the vehicle deviates from a lane or not is judged; under the condition that the vehicle deviates from the lane to run, vibration parameters corresponding to the current vehicle speed are obtained; and according to the vibration parameters, an EPS system motor is controlled to vibrate a vehicle steering wheel according to the amplitude and/or frequency corresponding to the vibration parameters. According to the method provided by the embodiment of the invention, when the vehicle deviates from the lane, the early warning of the corresponding intensity degree is sent out according to the current vehicle speed of the vehicle, so that the intensity degree of the vehicle deviation early warning is matched with the user perception degree and the danger degree of vehicle driving, and the early warning effect of vehicle deviation is improved; the occurrence rate of traffic accidents is reduced while the vehicle driving experience of the user is optimized.
本发明提供了一种车辆偏离的随速预警方法、系统和车辆,所述方法获取驾驶信息;获取驾驶信息;分析所述驾驶信息,判断车辆是否偏离车道行驶;在所述车辆偏离车道行驶的情况下,获取当前车速对应的振动参数;根据所述振动参数,控制EPS系统电机按照所述振动参数对应的振幅和/或频率振动车辆方向盘。本发明实施例所述的方法在车辆偏离车道行驶时,根据车辆的当前车速发出相对应的强烈程度的预警,使车辆偏离预警的强烈程度与用户感知度、车辆行驶的危险程度相匹配,提升了车辆偏离的预警效果,在优化用户的车辆驾驶体验的同时,降低交通事故的发生率。
