  • Steering system, abnormality determination method, and non-transitory storage medium
    Patent number: 11440577
    Abstract: A steering system includes a first operation device including a first displacement mechanism, a first electric drive source, and a first detector, a second operation device including a second displacement mechanism, a second electric drive source, and a second detector, and a determiner configured to determine that the first operation device and the second operation device do not malfunction when the determiner determines that the first operation device has an abnormality based on first operation information related to operation of the first operation device, and that the second operation device has an abnormality based on second operation information related to operation of the second operation device.

  • Vehicle door outside handle device, vehicle door, and vehicle
    Patent number: 10815704
    Abstract: A vehicle door outside handle device includes a through hole opening toward a vehicle rear side in a protrusion portion from a door side wall. An optical lens and an imaging element disposed in the through hole toward the vehicle rear side captures a vehicle rear side image including a vehicle side wall image.

  • Rotation angle detecting device
    Patent number: 9605974
    Abstract: In a rotation angle detecting device, a first magnetic sensor and a second magnetic sensor are disposed at an interval of an electrical angle of 120 degrees around a rotation center axis of a rotor. An output signal of the first magnetic sensor is expressed by V1=sin ?, and an output signal of the second magnetic sensor is expressed by V2=sin(?+120). A determination device determines whether both the magnetic sensors are normal, or there is a failure in at least one of the magnetic sensors, based on whether an expression of L?V12+V22+V1·V2?0.75?U is satisfied, where L is a lower limit and U is an upper limit.
