<P>PROBLEM TO BE SOLVED: To suppress the generation of surge voltage due to a connection cable, when exchanging power with the outside, and utilizing the neutral point of a dynamo-electric machine. <P>SOLUTION: A control system 10 for vehicle is equipped with a motor generator 14, a control unit 50, a power circuit 60, and an external connection cable 80. A motor generator 14 has a terminal block 30, and the terminal block 30 is provided with a neutral line terminal 29, which is connected with a neutral line 28 drawn out of the neutral point of each phase coil of a stator 16, an external terminal 38 which is connected to the external connection cable 80, and a relay 40 which can switch the connection state between the neutral line terminal 29 and the external terminal 38, in between a nonconducting state and a conducting state. The control unit 50 switches the connection state in the relay 40, from a nonconducting state to a conducting state, when exchanging power with an outside, making use of the neutral point and using the external connection cable 80. <P>COPYRIGHT: (C)2009,JPO&INPIT |
