The invention provides a dump truck light and heavy load detection method, a dump truck light and heavy load detection device and a dump truck, and the dump truck light and heavy load detection methodcomprises the steps: obtaining a signal of a first ultrasonic probe, and judging whether tarpaulin is folded or not according to the signal of the first ultrasonic probe; acquiring a signal of a lifting sensor, and judging whether the carriage is lifted or not according to the signal of the lifting sensor; acquiring a signal of a second ultrasonic probe, judging the loading state of the dumper according to the signal of the first ultrasonic probe, the signal of the second ultrasonic probe and the signal of the lifting sensor. According to the invention, a detection process can be automatically executed without manually pressing a button by a driver in a dump truck light and heavy load detection mode; the continuity of the detection process is guaranteed, the detection process does not involve oil consumption detection of the dumper and is not easily influenced by road conditions and strokes, equipment for weighing the dumper does not need to be installed on the ground, hardware cost is saved, and installation difficulty is reduced.

    本发明提供了一种自卸车轻重载检测方法、自卸车轻重载检测装置和自卸车,其中,自卸车轻重载检测方法包括:获取第一超声波探头的信号,根据第一超声波探头的信号,判断篷布是否收拢;获取举升传感器的信号,根据举升传感器的信号,判断车厢是否举升;获取第二超声波探头的信号,根据第一超声波探头的信号、第二超声波探头的信号和举升传感器的信号判断自卸车的载重状态,本发明中对自卸车轻重载的检测方式不需要驾驶员手动按动按钮而自动执行检测过程,保证了检测过程的持续性,检测过程没有涉及对自卸车的油耗检测,不易受到路况和行程的影响,自卸车轻重载检测方法不需要在地面上安装对自卸车进行称重的设备,节省硬件成本,降低安装难度。
