control strategy for a 42-v waste-heat thermoelectric vehicle

 

a 42-v waste-heat thermoelectric vehicle is employed as a potential application of thermoelectric generators for fuel economy improvement and emissions reduction. the 42-v waste-heat thermoelectric vehicle currently in development employs an assemblage driving system consisting of a waste-heat thermoelectric generator, a 42-v powernet, and an integrated starter and generator (isg). the waste-heat thermoelectric generator also functions as a power supply. to optimize the utilization of the waste-heat energy generated by the thermoelectric generator, an electric assist control strategy and a torque split control strategy are proposed herein. through the development of relevant systems and strategies, including the thermoelectric generator and an electric bus system, two vehicle models are established and compared using the advisor platform based on matlab/simulink. the calculation results show improved fuel economy and emissions performance resulting from the integration of the torque split control strategy into the 42-v waste-heat thermoelectric vehicle.
