Description

Vehicle command input device, system including the same, and vehicle command input method Cross Reference to Related Applications This application claims the priority rights of korean patent application No. 10-2020-0075888 filed in the korean intellectual property office on month 22 of 2020, the entire contents of which are incorporated herein by reference. Technical Field The present disclosure relates to a vehicle command input device, a system including the same, and a vehicle command input method, and more particularly, to a technique of providing a vehicle service by measuring a force applied to a steering wheel. Background The vehicle is equipped with an air conditioning device for providing a comfortable driving environment to the driver or Audio Video Navigation (AVN) or the like for providing driving convenience and audiovisual enjoyment of the driver. In general, an input device for operating such an air conditioner or AVN is separately provided in a center instrument panel of a vehicle. Therefore, during driving, the driver needs to move the driver's forward-facing line of sight to the input device, and needs to move the hand from the steering wheel to the input device to operate the air conditioner or AVN. As described above, operating the air conditioner or AVN during driving of the vehicle distracts and distracts the driver from the forward direction, thereby increasing the possibility of occurrence of traffic accidents. In order to reduce the risk of accidents due to the operation of the air conditioner or AVN, a remote controller may be provided in the steering wheel. However, the driver needs to move the line of sight to find the operator for a desired input, or needs to look around to find the operator, which makes the driver neglect driving and reduces the convenience of the driver. Accordingly, a technology has been developed to allow a driver to perform a desired operation by tapping or scraping a steering wheel, or to provide a vehicle service by inputting a voice keyword. But may cause an input error due to surrounding noise when a driver listens to music or opens a window.
