Title:
ACCELERATION AND DECELERATION CONTROLLING DEVICE FOR VEHICLE EQUIPPED WITH CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2002187464
Kind Code:
A
Abstract:

To improve control performance in acceleration and deceleration control after saturation of an operation quantity to a controlling object is settled.

This is a controlling means for calculating operation quantities TeL* and IpL* of an engine and a continuously variable transmission by a model following control method using a state space method. This controlling means is provided with a standard model 31 which outputs an acceleration command value α ref for indicating desirable responsivity for an acceleration estimated value αwf to a target acceleration αw*, an acceleration deviation integrator 32 which integrates deviation between the acceleration command value αref and the acceleration estimated value αwf, and a state feedback part 33 which calculates the operation quantities TeL* and IpL* by performing feedback of state quantities Xm and Xp of the standard model 31 and a controlling object, a vehicle model 35 and an acceleration deviation integrating quantity Xi. When it is detected that the operation quantities TeL* and IpL* are over the limit value, the operation quantities TeL* and IpL* are offset only for the quantities over the limit value. When all the operation quantities TeL* and IpL* are over each limit value, the integration of acceleration deviation by the acceleration deviation integrator 32 is stopped.
