<p><P>PROBLEM TO BE SOLVED: To improve the safety of an electric automobile which can travel by using a creeping torque. <P>SOLUTION: The electric automobile includes motor generators for driving its wheels. In the low-speed time region when the electric automobile starts, a creep torque is output from the motor generators even when an accelerator pedal is not being operated run it moderately. Also, the electric automobile includes a frictional braking system for braking a vehicle by a frictional force. An EV controlling unit for setting a desired creep torque of the motor generators sets the creep torque so as to be lowered in comparison with an ordinary time (a step S30), when the generation of an abnormality is recognized in the frictional braking system (a step S20). Thereby, a propelling force of the electric automobile can be reduced even in the state where an abnormality is generated in the frictional braking system and the possibility of the reduction of the braking force is present. Therefore, the safety of the electric automobile can be improved. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
