<P>PROBLEM TO BE SOLVED: To provide a vehicular control system that selects an electric motor driving system keeping the system efficiency as high as possible on the basis of comprehension of conditions of the vehicle and components mounted therein. <P>SOLUTION: A drive signal processing section 140 of a motor controller 100 outputs, to a rotary electric machine 4, a driving signal of a first driving system or a second driving system whose switching loss is smaller than that of the first driving system, according to the torque requested to the rotary electric machine 4. A driving system setting section 130 performs switching from the first driving system to the second driving system on the basis of conditions of the electrical machine components of the vehicle or the running condition of the vehicle when any of rotary electric machine operation points of the first driving system and the second driving system can be selected. <P>COPYRIGHT: (C)2010,JPO&INPIT |
