The invention discloses a safe steering warning method and device based on real vehicle calibration, and the method comprises the steps: setting a piecewise linear difference function according to the road driving condition of a vehicle; a plurality of continuous vehicle speed intervals are set, in one vehicle speed interval, the piecewise linear difference function is an interval linear function, the boundary speed is the calibrated vehicle speed, and the steering wheel angular speed corresponding to the calibrated vehicle speed is the calibrated angular speed; the vehicle steering wheel angular velocity and the vehicle speed are monitored in real time, and when the vehicle speed is in a vehicle speed interval, the monitored vehicle steering wheel angular velocity is not smaller than the steering wheel angular velocity corresponding to the interval linear function at the vehicle speed, and a safe steering warning is given out; the steering operation of a driver can be monitored in real time, and if the rotating speed of the steering wheel operated by the driver is too high, an alarm is given to the driver, so that the safety consciousness of the driver is enhanced, a good driving habit is developed, sideslip accidents caused by the too high rotating speed of the steering wheel during vehicle turning are reduced, and great significance is achieved for reducing the traffic accident rate.
本发明公开了一种基于实车标定的安全转向警示方法及装置,其中,方法包括根据车辆道路行驶工况,设置分段线性差值函数;设置多个连续的车速区间,在一个车速区间内分段线性差值函数为区间线性函数,边界速度为标定车速,标定车速相应的方向盘角速度为标定角速度;实时监测车辆方向盘角速度和车速,当车速处于一个车速区间时,监测车辆方向盘角速度不小于此车速下区间线性函数对应的方向盘角速度,则发出安全转向警示;本发明能够实时对驾驶员的转向操作进行监控,若驾驶员操作方向盘转速过快,向驾驶员发出警示,从而增强驾驶员的安全意识,养成良好的驾驶习惯,降低车辆转弯时因方向盘转速过快所造成的侧滑事故,对交通事故率的降低有很大意义。
