Abstract: For light trucks equipped with electronic stability program (ESP), the built-in acceleration and roll angle sensors are easily stimulated by vehicle vibrational excitation, resulting in an amplification effect that causes the ESP/vehicle dynamic control (VDC) function to be triggered incorrectly. This paper describes two schemes of hardware brake pipe design optimization and software algorithm optimization for VDC error triggering. After theoretical and real vehicle verification, it is very effective to prevent the VDC function from triggering by mistake. The scheme is innovative and has certain engineering application value.
