Description

technical field

[0001] The invention relates to a steer-by-wire steering device. Background technique

[0002] In the steering steering device for a vehicle disclosed in JP-A-2001-114123 as a steer-by-wire steering device, the rotational operation member and the wheels are not mechanically connected. The steer steering actuator controlled according to the rotational operation amount of the rotational operation member steers the wheels.

[0003] In the steer-by-wire type steer-by-wire device described above, the structure for detecting the rotation of the rotary operation member is important, and if an abnormality occurs in this structure, the steering cannot be steered even if the steering actuator is normal. In Japanese Patent Application Laid-Open No. 2001-114123, only one angle sensor is provided as a structure for detecting the rotation of the rotary operation member. In the steering system disclosed in Japanese Patent Application Laid-Open No. 10-278826, a main steeri...
