The invention discloses a vehicle rollover early warning and reminding method. The method comprises the following steps that the speed v of a vehicle and the turning angle omega of a steering wheel are collected; when v is greater than 0, and omega is greater than 0; a relation function between the vehicle speed and the steering wheel turning angle is established, and the relation function between the vehicle speed and the steering wheel turning angle is that f (v, omega) is calculated, and when f (v, omega) is larger than or equal to 0, a rollover early warning signal is sent to an instrument panel. According to the technical scheme, the possibility of rollover of the vehicle is calculated and predicted in real time according to the speed v of the current vehicle and the turning angle omega of the steering wheel, a driver is reminded to effectively decelerate or set a proper steering wheel angle in time on an automobile instrument, and a vehicle rollover accident is warned as much as possible.

    本发明公开一种预警车辆侧翻及提醒方法,包括以下步骤:采集车辆的速度v和方向盘的转角ω;当v大于0,且ω大于0;建立车速与方向盘转角的关系函数,车速与方向盘转角的关系函数为:计算f(v,ω),当f(v,ω)大于等于0时,向仪表盘发出侧翻预警信号。本发明的技术方案根据当前车辆的速度v和方向盘的转角ω实时计算,预测车辆侧翻的发生的可能,及时在汽车仪表提醒驾驶员有效减速或设置合适的方向盘角度,以最大可能预警车辆侧翻事故。
