Claims

[Scope of utility model registration request]

In order to turn on and off the information from the spatial wave source, one of the rotating part on the steering wheel side and the fixed part on the vehicle body side close to this is provided with on-region and off-region with a long circumferential length alternately on the circumference. A first and a second switching board are provided with a switching board disposed along the switching board, and the first and second switching boards receive on/off information from the switching board and output pulse train electrical signals having a phase shift of 174 cycles from each other depending on the steering state of the steering wheel. a spatial wave receiving member, and a computing unit capable of receiving each pulse train electric signal from the first and second spatial wave receiving members to calculate the steering state of the steering wheel;
A steering state calculation device characterized in that the first and second spatial wave receiving members are provided adjacent to each other in the circumferential direction.
