Multifunctional key control method and key structure of automobile steering wheel

Abstract

The invention discloses a multifunctional key control method of an automobile steering wheel. After an automobile is started, multifunctional keys give user operation instructions to an automobile instrument and an automobile sound system, and when a switching instruction is received, the same key group only gives the user operation instructions to the automobile instrument or the automobile soundsystem according to currently switched control equipment. The multifunctional key control method of the automobile steering wheel has the advantages that a series of defects of multifunctional switches of an existing steering wheel are overcome; the number of the switches is reduced, and the cost of the whole automobile is saved; the simple and visual process is achieved, the multifunctional keysare design highlights of the whole automobile, and the product competitiveness is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to steering wheel technology. Background technique [0002] As the design of automobiles pays more and more attention to human-computer interaction, human operation experience and driving comfort, most of the current automobiles will integrate steering wheel multi-function switches, which are respectively distributed on the left and right sides of the steering wheel surface, called It is the left steering wheel switch and the right steering wheel switch. It is mainly used to control the audio system, instrumentation, active cruise system, constant speed cruise system, active speed limit function, steering wheel heating and many other functions. However, the space on the surface of the steering wheel is limited. space, and the operating space for turning the steering wheel by hand, basically there is very little space for the layout of the steering wheel multi-function switch. How to integ...

Problems solved by technology

[0009] 1. In the first solution, due to the inconsistency in the number of the left steering wheel switch and the right steering wheel switch, it will cause asymmetry on both sides and affect the appearance; at the same time, due to the excessive number of buttons on each side, so many buttons are integrated in a limited area. Buttons will cause the size of the buttons to be too small, inconvenient to operate, affect the requirements of ergonomics, or cause misuse, cause customers to complain, and affect the establishment of the brand

[0010] 2. The second solution requires a separate handle. Although it can reduce the number of steering wheel switches, it will increase the cost a lot; and the layout space of the whole vehicle is limited, and one more component will propose new adjustments to the layout of the whole vehicle

[0011] 3. In the third solution, because the instrument and audio are integrated on the same side, there are 14 buttons in total. Arranging so many buttons in a limited area will inevitably lead to a very small button size, which does not meet the requirements of ergonomics. Therefore, in order to To solve this problem, it is necessary to simplify the control buttons of the audio system and the instrument, and the cancellation of these commonly used shortcut keys will inevitably affect the user experience, cause customers to complain, and affect the sales of the whole vehicle
