CONTROL DEVICE FOR VEHICLE
First Claim
1. A control device for a vehicle, comprising:
- an electric motor that outputs a driving force for travel;
a transmission that is provided on a power transmission path extending from the electric motor to a drive wheel and performs a shift operation by modifying an engagement state of a frictional engagement element;
a transmission control portion that controls the shift operation of the transmission;
a temperature recognizing portion that estimates or detects a temperature of the electric motor; and
a shift operation correcting portion that corrects a control amount of the shift operation performed in the transmission by the transmission control portion, on the basis of the temperature of the electric motor estimated or detected by the temperature recognizing portion.

Abstract
In a hybrid vehicle that speed-shifts the output of a motor/generator using an automatic transmission and transmits the speed-shifted output to a drive wheel, a magnet temperature of the motor/generator is estimated, and when the magnet temperature is higher than a reference temperature, an oil pressure command value for engaging or disengaging a brake of the automatic transmission is corrected in a decreasing direction, thereby preventing tie-up shock. When the magnet temperature is lower than the reference temperature, on the other hand, the oil pressure command value for engaging or disengaging the brake of the automatic transmission is corrected in an increasing direction, thereby avoiding racing in the motor/generator.
