<P>PROBLEM TO BE SOLVED: To provide a steer-by-wire system with excellent mountability on a vehicle capable of steering a steering wheel according to the operation of a steering wheel, even if a motor driving control circuit fails. <P>SOLUTION: In this steer-by-wire system 10, the vehicle can be evacuated to a road shoulder, etc. by steering the steering wheel 50 by a mechanical rectifier 35 according to the operation of the steering wheel, even if an ECU 60 or each position sensor 29 and 32 fails during a traveling. When driving a brushless motor 20 by the mechanical rectifier 35, the position sensors 29 and 32 are not required to have redundancy since detection results of the position sensor 29 and 32 are not required, to reduce an installation space. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
