Steering wheel device with hands-off detection (hod)

A steering wheel device with hands-off detection (HOD), comprising:

• a steering wheel having a manipulation ring defining a central axis, wherein the manipulation ring includes a left holding segment and a right holding segment;
• and
• a holding sensing module assembled to the steering wheel and including:
• a plurality of left sensing electrodes each having an elongated shape and disposed on the left holding segment of the manipulation ring, wherein the left sensing electrodes include a plurality of first left electrodes and a plurality of second left electrodes that are staggered with the first left electrodes, and wherein a width of each of the first left electrodes is different from a width of any one of the second left electrodes;
• and
• a plurality of right sensing electrodes each having an elongated shape and disposed on the right holding segment of the manipulation ring, wherein the right sensing electrodes include a plurality of first right electrodes and a plurality of second right electrodes that are staggered with the first right electrodes, and wherein a width of each of the first right electrodes is different from a width of any one of the second right electrodes;
• wherein the first left electrodes are electrically coupled to the second right electrodes, respectively, and the width of each of the first left electrodes is different from the width of the corresponding second right electrodes;
• and wherein the second left electrodes are electrically coupled to the first right electrodes, respectively, and the width of each of the second left electrodes is different from the width of the corresponding first right electrodes.
