STEERING CONTROL DEVICE AND STANDARD VALUE ADJUSTMENT METHOD
A steering control device includes a control unit. The control unit is configured to execute a control angle calculation process, an angle feedback process, and a standard value adjustment process. The control angle calculation process is a process of calculating a control angle as an absolute angle relative to a standard value, and the angle feedback process is a process of performing feedback control on the control angle, and the standard value adjustment process is a process of adjusting the stored standard value. The standard value adjustment process includes a process of, when, in a straight-ahead state, the control angle deviates from a value showing the straight-ahead state, adjusting the standard value such that the deviation of the control angle from the value showing the straight-ahead state decreases.
Heating and capacitive sensing device for a steering wheel of a vehicle
A heating and capacitive sensing device for a steering wheel of a motor vehicle. The device includes a support made from an electrically insulating flexible material to which at least an electrically conductive first track and at least an electrically conductive second track are fixed.
