Problems solved by technology
For example, if a user wants to listen to a radio station on the 100MHz channel, and is currently in the 87.5MHz frequency band, he needs to manually adjust the knob from 87.5MHz to 100MHz. According to the general design, it needs to rotate at least 80 steps to reach this frequency band, and the rotation time is relatively long.
However, when the problem of too long rotation time is solved by increasing the step size, it will inevitably result in less radio frequency bands received.
Even if the automatic search function is set in some radio systems, if the user is in a location with a better signal, there may be many stations in the 87.5MHz-100MHz (or 87.5MHz-108MHz-100MHz) band. In this way, the user still have to rotate multiple times to get the precise positioning of the station
It can be seen that the design of using the knob to manually adjust the channel is not perfect and lacks humanized design

Embodiment Construction
[0018] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below with reference to the drawings and embodiments.
[0019] The method of using the knob for fast frequency modulation selection disclosed by the present invention is based on real-time analysis of the user’s operation speed in the tuning process, and responds quickly, automatically adjusts the frequency modulation step length corresponding to the rotation of the knob, and realizes the function of fast frequency modulation selection . In the method, first set a frequency adjustment step corresponding to one grid of radio knob rotation, which is called the default step size STEP, that is, every time the knob rotates one grid, the corresponding radio frequency is stepped or stepped back by a default step size STEP , and then adjust the step size corresponding to each rotation of the knob according to the speed at which the operator adjusts the...

The invention relates to a method for quick frequency modulation and channel selection by using a knob. The method comprises the following steps of: setting a default step, wherein the frequency of a radio station correspondingly gets forwards or backwards by a default step every time when the knob is turned by a grid; subsequently adjusting the step corresponding to every turn of a grid of the knob according to the speed of adjusting the knob by a user and interruption frequency produced in adjustment of the knob; and circulating in turn until the frequency point radio station required by the user is found. By using the method, the frequency of adjusting the radio station by the user by using the knob can be effectively increased, the user experience is improved, and the market competition of a product can be improved for an in-vehicle infotainment system manufacturer.
Description
Technical field [0001] The invention involves a radio knob design, which specifically involves a method that can use the knob to achieve a fast frequency adjustment table. Background technique [0002] Most vehicle multimedia systems have radio functions, and the function of the knob manual platform is still kept in many high -end or low -end multimedia systems.For example, if the user wants to listen to the radio station on Channel 100MHz, it is currently on the 87.5MHz frequency band, and it needs to be adjusted from 87.5MHz to 100MHz by manual knob. According to the general design, it is necessary to move at least 80 steps to reach the frequency band. The spinning time is longer.EssenceWhen the steps are increased to solve the problem of too long, it will inevitably lead to less frequency bands received.Even though there are automatic search functions in some radio systems, if the user is in a location with a better signal, there may be many radio stations in the 87.5MHz-100MH...
