This paper constructs a whole vehicle model of hybrid vehicle with integrated thermoelectric generation sys-tem from the perspective of improving the economy of hybrid vehicle.Meanwhile,with the control objective of maintaining the stability of battery SOC,the energy distribution of the TEG system and the switching strategy of the whole vehicle op-erating mode are designed,combined with the vehicle model to verify and analyze the joint simulation.The results show that the hybrid vehicle with TEG system can achieve fuel savings of 3.25％and 2.19％under NEDC and WLTC operat-ing conditions while improving tailpipe emissions.Under the influence of the control strategy,the TEG system is effective in supplementing the battery power,and the change rate of the power battery SOC under the two working conditions is 0.6％and 8％,which is basically maintained near the initial value.
