<p><P>PROBLEM TO BE SOLVED: To provide a collaboration control device of an engine and a continuously variable transmission, for successfully performing reproduction of a DPF, and suppressing deterioration in fuel consumption. <P>SOLUTION: The collaboration control device of the engine 10 and the continuously variable transmission 200 includes: a soot accumulated amount estimation means 81 for estimating soot accumulated amount onto a DPF 80; a reproduction decision means for determining the validity/invalidity of the reproduction execution of the DPF; an engine control means 100 for changing the driving state of the engine based on the output of the reproduction decision means; and a shift control means 250 for setting the transmission gear ratio of the continuously variable transmission. The engine control means sequentially executes reproduction start control for making it possible to ignite a soot according to the decision of reproduction execution by the reproduction decision means and reproduction continuation time control for making it possible to continue the combustion of the soot in ignition, and the shift control means increases the transmission gear ratio in comparison with a normal time in executing the reproduction start time control, and increases the transmission gear ratio in comparison with the normal time, and decreases the transmission gear ratio in comparison with the case of executing the reproduction start time control in executing the reproduction continuation time control. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
