HYBRID VEHICLE AND METHOD OF CONTROLLING THE SAME

摘要

A hybrid vehicle can be motor driven only by the output of a rotating electrical machine using the electrical power of an in-car electrical storage device in the inside region of the maximum output line (350) of a motor running in EV mode and in the inside region of the maximum output line (340) of a motor running in EV mode. Each maximum output line (340, 350) is made up of linear portions defining the upper limit torque (TMmax) and the upper limit vehicle speed (VMmax) within a running motor and a curved portion defining the upper limit output power. Thus, when the vehicle speed exceeds the upper limit vehicle speed within the running motor, an engine is started in each an EV mode and an HV mode. The upper limit vehicle speed (VMmax (EV)) in the motor running in EV mode is set to be lower than the upper limit vehicle speed (VMmax (HV)) in the motor running in HV mode.
