Hybrid type vehicle driving controller, hybrid type vehicle driving control method and its program
First Claim
1. A hybrid type vehicle driving controller comprising electric generator maximum torque calculation processing means for calculating electric generator maximum torque showing a maximum value of electric generator torque;
- electric generator target torque calculation processing means for calculating electric generator target torque showing a target value of the electric generator torque;
deficient electric generator torque calculation processing means for calculating a deficient amount of the electric generator torque on the basis of the difference between said electric generator target torque and the electric generator maximum torque;
engine maximum torque calculation processing means for calculating plural engine maximum torques on the basis of at least said electric generator maximum torque and the deficient amount of the electric generator torque; and
engine limit torque calculation processing means for calculating a minimum value of said respective engine maximum torques as engine limit torque.

Abstract
The invention has an engine maximum torque calculating processor for calculating plural engine maximum torques showing a maximum value of engine torque, and an engine limit torque calculating processor for calculating a minimum value of the respective engine maximum torques as engine limit torque. Because the minimum value of the engine maximum torques is calculated as the engine limit torque, it is possible to reliably prevent the engine from entering an excessive rotating state. Further, because the engine limit torque is calculated on the basis of the minimum value of the engine maximum torques, the engine limit torque can be reliably calculated even when there is an individual difference in the engine, an electric generator, etc. and there are calculation errors further, for example, electric generator target torque and the electric generator maximum torque.
