According to the touch control type steering wheel, the key areas are arranged on the left portion, the right portion and the lower portion of the steering wheel, the usable space of the steering wheel is fully utilized, the touch control keys are combined, and the reasonability of the key layout of the steering wheel is improved. According to the invention, integrated electric control design is carried out through a first control chip, a second control chip, a third control chip and a fourth control chip, and key areas controlled by the second control chip, the third control chip and the fourth control chip can be managed through the first control chip, so that the control management of each function is more centralized; the information transmission efficiency of the steering wheel circuit is improved. Compared with the prior art, the steering wheel has the advantages that a user can quickly select required functions during driving, and when the functions need to be adjusted, the functions are changed by rewriting programs stored in the control chip, physical keys do not need to be manufactured again, so that the manufacturing, maintenance and transformation costs of the steering wheel are reduced, and the usability of the steering wheel is improved.
本发明提供了一种触控式方向盘,通过在方向盘的左部、右部以及下部设置按键区域,充分利用了方向盘的可使用空间,并结合触控按键,提高了方向盘按键布局的合理性。本发明还通过第一控制芯片、第二控制芯片、第三控制芯片以及第四控制芯片进行集成式电控设计,能够通过第一控制芯片管理第二控制芯片、第三控制芯片和第四控制芯片所控制的按键区域,使得每个功能的控制管理更加集中,提高了方向盘电路的信息传输效率。相比于现有技术,本发明有利于用户在驾驶时能够快速选择所需的功能,且在需要功能调整时,通过改写控制芯片中存储的程序进行功能更改,无需重新制作物理按键,降低了方向盘的制造、维修以及改造等成本,提高了方向盘的可用性。
