COOPERATIVE CONTROLLER FOR PRIME MOVER AND AUTOMATIC TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a cooperative controller for an automatic transmission and a prime mover capable of shortening the acceleration response time to the generation of driving force in the accelerating operation in coasting running. SOLUTION: When a control starting condition judging means 102 judges that the starting condition of output increasing control is established on the basis of the accelerating operation of a vehicle in the coasting running state of the vehicle in which a one-way clutch F2 is released, an output increasing control means 116 increases output of an engine 10 by the specified amount in comparison with a value of a case where it is not judged that the starting condition is established, the time TRE to the time when the input shaft rotational speed NCO of an automatic transmission 14 reaches the synchronous rotational speed (NOUT×γ1) as a product of the change gear ratioγ1 multiplied by the output shaft rotational speed NOUT is shortened, and therefore, the acceleration response time from the accelerating operation of the vehicle to the generation of driving force generated by the engagement of the one-way clutch F2 is shortened, a delaged feeling is eliminated, and the drivability of the vehicle is improved.
