The invention discloses an automatic control method for an automobile lane changing steering lamp, which belongs to the technical field of automobile steering lamp control, and comprises the following steps of: acquiring a steering wheel rotation angle and a current automobile speed of each lane changing in sample automobile working condition data to obtain a plurality of angle automobile speed data sets; obtaining a vehicle steering angle range based on a least square method and the vehicle speed data set at each angle; based on the centrifugal torque and the weight torque during turning of the vehicle, the maximum steering angle of the vehicle at the actual driving speed is calculated through a vehicle limit steering angle method; based on the vehicle steering angle range and the maximum steering angle, a BCM controller is used for conducting steering lamp automatic control and rollover early warning; the method solves the problem that an existing steering lamp automatic control method does not consider the environment vehicle state and the intention of a driver, and consequently mistaken turning-on is caused.

    本发明公开了一种汽车变道转向灯自动控制方法,属于车辆转向灯控制技术领域,包括如下步骤:获取样车工况数据中每次变道的方向盘转动角度和车辆当前车速,得到若干角度车速数据组;基于最小二乘法和各角度车速数据组,得到车辆转向角度范围;基于车辆过弯时的离心力矩和重量力矩,并利用车辆极限转向角度方法,计算得到车辆实际驾驶速度下的最大转向角度;基于车辆转向角度范围和最大转向角度,利用BCM控制器进行转向灯自动控制和侧翻预警;本发明解决了现有转向灯自动控制方法没有考虑环境车辆状态和驾驶员意图导致误亮的问题。
