A vehicle-mounted fragrance control method and system

Abstract

The present invention relates to a vehicle-mounted fragrance control method and system. The method includes fragrance activation; power-on self-check of the fragrance to determine whether a fault occurs; if the self-check is normal, fragrance status monitoring is judged; if a fault exists, whether LIN communication is normal is judged; if the fragrance is activated, the state before power-off is maintained; if it is not activated, the default fragrance state is restored; thereafter, the user manually selects a fragrance mode; if the LIN communication is normal, whether the fan works normally is judged; if the communication is abnormal, it is judged as a fragrance LIN communication fault; if the fan works normally, whether the switching motor works normally is judged; if the fan does not work normally, it is judged as a fan fault; if the switching motor does not work normally, it is judged as a switching motor fault. For the vehicle-mounted fragrance control method, every operation of the user can release multiple scents simultaneously. The concentration will change with time according to the usage scenario to simulate the natural environment, and the concentration is variable. At the same time, the music of the garden scene is played to create a wonderful experience of strolling in the garden.

Description

Technical Field

[0001] The present invention belongs to the technical field of automobiles, and particularly relates to a vehicle-mounted fragrance control method and system. Background Art

[0002] With people paying more and more attention to the air quality in the vehicle, vehicle-mounted fragrances gradually appear in passenger cars. The fragrance released by the fragrance can make people feel happy and refresh the mind, thus providing a more comfortable driving environment and improving driving safety at the same time.

[0003] Traditional vehicle-mounted fragrance control is divided into fragrance selection and concentration adjustment. For each operation of the user, the fragrance selection can only choose one from a variety of fragrances, and the concentration adjustment can only be adjusted to one concentration from a variety of concentrations, such as the second gear concentration of rose fragrance.

[0004] Based on this, it is necessary to develop a new vehicle-mounted fragrance control method to effectively solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a vehicle-mounted fragrance control method and also provide a vehicle-mounted fragrance control system to solve the problem of breaking the single fragrance and concentration adjustment of traditional vehicle-mounted fragrances, realizing the release of multiple concentrations and multiple fragrances, simulating natural scenes, such as garden scenes and forest scenes, etc., and playing the music of the corresponding scene at the same time, combining vision and hearing to enhance the sense of ceremony and driving experience.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A vehicle-mounted fragrance control method includes the following steps:

[0008] A. Turn on the fragrance;

[0009] B. Perform power-on self-check of the fragrance to determine whether a fault occurs;

[0010] C. If the self-check is normal, judge the fragrance status monitoring; if a fault exists, judge whether the LIN communication is normal;

[0011] D. If the fragrance is turned on, maintain the state before power-off; if it is not turned on, restore the default fragrance state; then, the user manually selects the fragrance mode;

[0012] E. If the LIN communication is normal, judge whether the fan works normally; if the communication is abnormal, judge it as fault warning 1, that is, fragrance LIN communication fault;

[0013] F. If the fan works normally, judge whether the switching motor works normally; if the fan does not work normally, judge it as fault warning 2, that is, fan fault;

[0014] G. If the switching motor malfunctions, it is determined as Fault Warning 3, i.e., the switching motor fails.

[0015] Further, in step C, the fragrance status monitoring determines whether the fragrance was turned on before the last power-off.

[0016] Further, in step D, the fragrance modes are: Garden Mode, Forest Mode, and Fruity Mode.

[0017] Furthermore, in Garden Mode, the fragrance switching motor realizes the switching of rose fragrance (60s) - jasmine fragrance (60s) - cherry blossom fragrance (60s) - rose fragrance (60s); the fan speed is adjusted to simulate the natural environment.

[0018] Furthermore, in Forest Mode, the fragrance switching motor realizes the switching of pine fragrance (60s) - grass fragrance (60s) - soil fragrance (60s) - pine fragrance (60s); the fan speed is adjusted to simulate the natural environment.

[0019] Furthermore, in Fruity Mode, the fragrance switching motor realizes the switching of watermelon fragrance (60s) - lemon fragrance (60s) - passion fruit fragrance (60s) - watermelon fragrance (60s); the fan speed is adjusted to simulate the natural environment.

[0020] A vehicle-mounted fragrance control system includes a control unit, a fan, a switching motor, and a housing with a flow channel inside; the controller, the fan, and the switching motor are all fixed inside the housing; the later-installed perfume can flow along the flow channel.

[0021] The control unit is a controller, and the fan and the switching motor are actuators; the control unit is connected to the fan and the switching motor for control; the fan is used to blow out the fragrance through the internal flow channel; the switching motor is used to switch the fragrance.

[0022] Further, the controller, the fan, and the switching motor are all fixed inside the housing by small screws.

[0023] Further, the rotation speed of the fan determines the concentration of the fragrance.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The present invention provides a brand-new vehicle-mounted fragrance control method. For each operation of the user, multiple fragrances can be released simultaneously, and the concentration will change over time according to the use scenario to simulate the natural environment. For example, when the user selects the garden scenario, the fragrance will release rose fragrance, jasmine fragrance, and cherry blossom fragrance, and the concentration can be changed. At the same time, the music of the garden scenario is played to create a wonderful experience of walking in the garden. The user can also choose the forest scenario, and the fragrance will release pine fragrance, grass fragrance, and soil fragrance, and the concentration can be changed. At the same time, the music of the forest scenario is played to create a pleasant feeling of hiking in the forest. Brief Description of the Drawings
