t.e emerging virt.al coupling t.chnology aims t. operat. mult.ple t.ain unit. in a Virt.ally Coupled t.ain Set.(VCt.) at.a minimal but.safe dist.nce. t. guarant.e collision avoidance, t.e safet. dist.nce should be calculat.d using t.e st.t.-of-t.e-art.space-t.me separat.on principle t.at.separat.s t.e Emergency Braking (EB) t.aject.ries of t.o successive unit. during t.e whole EB process. In t.is case, t.e minimal safet. dist.nce is usually numerically calculat.d wit.out.an analyt.c formulat.on. t.us, t.e const.ained VCt. cont.ol problem is hard t. address wit. space-t.me separat.on, which is st.ll a gap in t.e exist.ng lit.rat.re. t. solve t.is problem, we propose a Dist.ibut.d Economic Model Predict.ve Cont.ol (DEMPC) approach wit. comput.t.on efficiency and t.eoret.cal guarant.e. Specifically, t. alleviat. t.e comput.t.on burden, we t.ansform implicit.safet. const.aint. int. explicit.y linear ones, such t.at.t.e opt.mal cont.ol problem in DEMPC is a quadrat.c programming problem t.at.can be solved efficient.y.
