The invention discloses a multistage early warning anti-rollover method for a fire fighting truck. The method comprises the following steps: determining factors influencing the driving balance of the fire fighting truck and a factor information acquisition mode; establishing a fire fighting truck roll state evaluation model based on fuzzy logic; performing fuzzy reasoning according to the model; performing defuzzification to obtain balance state information of the fire fighting truck; early warning is given out according to the vehicle balance state, and multi-stage early warning and rollover prevention are achieved. The vehicle speed and the steering wheel rotation angle are used as reference quantities, and the problems that the response speed is low and misoperation is prone to occurring when a tilt angle sensor is independently used are solved; by establishing the fuzzy logic-based fire fighting truck roll state evaluation model and performing fuzzy reasoning and defuzzification, the balance state information of the fire fighting truck is quickly obtained and is transmitted to the anti-rollover controller, only the anti-rollover controller needs to be additionally arranged on the fire fighting truck, other equipment does not need to be additionally arranged, and the cost is low.

    本发明公开了一种消防车的多级预警防侧翻方法,包括以下步骤:明确影响消防车行驶平衡性的因素及其因素信息获取方式;建立基于模糊逻辑的消防车侧倾状态评估模型;根据模型进行模糊推理;解模糊化,得到消防车平衡状态信息;根据车辆平衡状态发出预警,实现多级预警防侧翻。本发明采用车速和方向盘转动角度两者作为参考量,避免单独使用倾角传感器反应速度较慢、容易误操作的问题;通过建立基于模糊逻辑的消防车侧倾状态评估模型,进行模糊推理和解模糊,从而快速的得到消防车平衡状态信息,将消防车平衡状态信息输送到防侧翻控制器,本发明在消防车上仅需增加防侧翻控制器,无需外加其它设备,成本低。
