The invention provides a heavy-duty truck safe compartment lifting method based on a suspension signal, and relates to the technical field of new energy trucks, and the method comprises the following steps: when a cab lifting signal is received, an air bag is inflated and deflated according to a height valve reading, and a cab is lifted; whether the difference value of the left suspension difference value and the right suspension difference value is not smaller than a third preset threshold value or not is judged before the cab is disengaged from the rear suspension part; if yes, the air cylinder stops jacking; otherwise, the lock catch is unlocked; after the cab is separated from the rear suspension part, whether the difference value of the left suspension difference rate and the right suspension difference rate is not smaller than a fourth preset threshold value or not is judged; if yes, the air cylinder stops jacking; otherwise, the air cylinder continues to jack until the cab is lifted. In the lifting process of the cab compartment, the suspension heights of the front suspension air bag and the rear suspension air bag are analyzed, safety identification is conducted on the two stages before and after the cab compartment is separated from the rear suspension part, the safety of the compartment is further guaranteed when the compartment is lifted, the cab compartment is effectively prevented from overturning, and the safety is high.
本发明提供一种基于悬置信号的重载货车安全升厢方法,涉及新能源货车技术领域,包括以下步骤:接收到驾驶室升起信号时,气囊根据高度阀读数进行充放气,驾驶室升起;在驾驶室脱离后悬置部前判断左侧悬置差值和右侧悬置差值的差值是否不小于第三预定阈值;是则气缸停止顶升;否则锁扣解锁;在驾驶室脱离后悬置部后判断左侧悬置差率和右侧悬置差率的差值是否不小于第四预定阈值;是则气缸停止顶升;反之气缸继续顶升至驾驶室升起完成。本发明在驾驶室车厢升起过程中,通过对前悬气囊和后悬置气囊的悬置高度进行分析,对驾驶室车厢脱离后悬置部前后的两个阶段进行安全识别,进一步保障车厢升起时车厢安全性,有效防止驾驶室车厢倾覆,安全性高。
