The invention discloses a commercial vehicle multi-target coordination control method considering a front vehicle safety speed effect, aims to realize a safer, more comfortable and more economical coordination control process of a commercial vehicle, and specifically comprises the following steps: (1) obtaining a vehicle driving state and environment information, comprise the front vehicle position, the front vehicle speed, the front vehicle maximum deceleration, the front vehicle body length, the self-vehicle position, the self-vehicle speed and the self-vehicle maximum deceleration; (2) calculating a safety sensing distance and a safety vehicle speed in a vehicle running and following process, and establishing a safety following rule considering a safety speed effect of a front vehicle; (3) putting forward a multi-target coordination control algorithm by considering longitudinal and vertical interaction, and adopting a semi-vehicle active suspension adaptive control algorithm considering uncertainty interference in the vertical direction; and the longitudinal dimension adopts a control algorithm of a fuzzy theory. According to the method, the safety speed effect model is introduced into commercial vehicle coordination control, so that the whole vehicle system is efficient, safe, comfortable and economical.
