[0028] The present invention will be further explained below in conjunction with the drawings:
[0029] Such as figure 1 with figure 2 As shown, the heavy-duty vehicle anti-rollover warning system based on sensing load and active braking receives the suspension displacement through the displacement sensor, and the lateral acceleration sensor receives the acceleration signal. The two signals are processed accordingly, and the calculated mechanical model is substituted into it Calculate the left front, left rear, right front and right rear support reaction forces; then substitute it into the lateral load transfer rate LTR model to calculate the real-time lateral load transfer rate. The specific steps are as follows:
[0030] (1) Install position sensors on the front, rear, left and right springs to measure the real-time spring lengths of the front, rear, left and right, according to the pressure value = spring stiffness coefficient and spring expansion (real-time spring length-spri...
