Abstract: Grip sensor includes base material, sensor wire formed on base material, and sensor circuit electrically connected to an end of sensor wire. Sensor wire includes first wire portion on a side of sensor end, and a second wire portion on a side of power source end. In a state where base material is attached on a rim, second wire portion is disposed at an outer peripheral surface of the rim that is a site opposing a knee or thigh of a driver operating a steering wheel, and first wire portion is disposed at a front side and a rear side of the rim.

Abstract: A vehicular power source device includes a first generator that generates electric power by rotating a rotor, a second generator that rotates at a higher rotation speed than an upper limit of a rotation speed of the first generator to generate electric power, a detector that detects the rotation speed of the first generator, and a controller that controls power generation of the first and second generators. The controller causes the first generator to generate electric power when the rotation speed of the first generator detected by the detector is not larger than the upper limit of the rotation speed of the first generator, and causes only the second generator to generate electric power when the rotation speed of the first generator detected by the detector is larger than the upper limit of the rotation speed of the first generator.
