METHOD FOR OPERATING HYBRID VEHICLE DRIVING STRUCTURE WITH TRANSMISSION

Japanese Patent JP3852322

B2

PROBLEM TO BE SOLVED: To correspond to a switching mode of a gear shift stage by making the most of a characteristic of a hybrid vehicle driving structure so that the driving of wheels is not affected when either one of a related engine or a second motor-generator fails, when incorporating a transmission in mid-way of a wheel drive shaft to obtain a required speed to axle torque characteristic by keeping fuel economy of an internal combustion engine in an excellent state without increasing the second motor-generator in scale, in the hybrid vehicle driving structure connecting an output shaft of the internal combustion engine to a first motor-generator and the wheel drive shaft via a power distribution mechanism and connecting the second motor-generator to the wheel drive shaft.
SOLUTION: When an operation of either one of the internal combustion engine or the second motor-generator is not in a normal state, a shift control of the transmission is corrected to correct the torque sharing of both of the internal combustion engine and the second motor-generator.
