The invention discloses a vehicle lane changing reminding method and device and a vehicle, and the method comprises the steps that the transverse displacement and the yaw angle of the vehicle are detected; when it is detected that the transverse displacement and the yaw angle both meet the lane changing conditions, the rotation angle and the steering wheel torque of a vehicle steering wheel are collected; the fitting degree with a preset lane changing curve is calculated according to the rotation angle and the steering wheel torque, when the fitting degree is larger than or equal to a lane changing threshold value, a lane changing reminding assembly is controlled to conduct lane changing reminding, and otherwise, the lane changing reminding assembly is controlled to stop lane changing reminding. Therefore, the problems that an existing vehicle cannot intelligently recognize the lane changing intention of a driver, the lane changing safety is reduced, and the intelligent driving requirement cannot be met are solved.
本申请公开了一种车辆变道提醒方法、装置及车辆,其中,方法包括:检测车辆的横向位移与偏航角度;在检测到横向位移与偏航角度均满足换道条件时,采集车辆方向盘的转动角度和方向盘扭矩;根据转动角度和方向盘扭矩计算与预设换道曲线的拟合度,其中,在拟合度大于或等于换道阈值时,控制变道提醒组件进行换道提醒,否则控制变道提醒组件暂停换道提醒。由此,解决了目前车辆无法智能识别驾驶员换道意图,降低变道安全性,且无法满足智能驾驶需求等问题。
