Optionally, in this step, the determining, according to the gesture type corresponding to the gesture touch information, a function to be controlled for the vehicle to be controlled includes:

For example, when the number of the corresponding touch points of the gesture touch information is 1, that is, when the user slides on the touch screen by means of 1 finger, the gesture type corresponding to the gesture touch information is determined to be a first type finger type, when the number of the corresponding touch points of the gesture touch information is 2, that is, when the user slides on the touch screen by means of 2 fingers, the gesture type corresponding to the gesture touch information is determined to be a second type finger type, and when the number of the corresponding touch points of the gesture touch information is 3, that is, when the user slides on the touch screen by means of 3 fingers, the gesture type corresponding to the gesture touch information is determined to be a third type finger type.

For example, when the second prompt information is prompted by adopting a vibration mode, the higher the air conditioner temperature is, the larger the vibration amplitude or the faster the vibration frequency of the vibration source is, the lower the air conditioner temperature is, the smaller the vibration amplitude or the slower the vibration frequency of the vibration source is, when the second prompt information is prompted by adopting a pure voice mode, and the content of the voice prompt is designed to be "pyridazin" sound, when the air conditioner temperature is higher, the higher the frequency of the "pyridazin" sound is, the denser the sound is, the lower the air conditioner temperature is, the lower the frequency of the "pyridazin" sound is, and the more sparse the sound is.
Further, in the step, a function upper limit value and a function lower limit value are set for the function to be controlled, and when the function to be controlled reaches the function upper limit value or the function lower limit value under the function regulation control of the function regulation information, the reminding of the second prompting information is stopped to prompt the user that the current function to be controlled is regulated to the function upper limit value or the function lower limit value, so that invalid regulation control operation of the user is prevented.
According to the method and the device, the function to be controlled which is required to be controlled by the user can be effectively determined through the gesture type corresponding to the gesture touch information, different functions to be controlled can be obtained based on the gesture type corresponding to the corresponding gesture touch information, different touch keys are not required to be set for different functions to be controlled, adjustment control of the functions to be controlled by the user is facilitated, false touch prevention operation of the user can be effectively eliminated through false touch prevention detection on the gesture touch information, accuracy of vehicle control is improved, function adjustment information is determined through the track direction of the gesture touch information, function adjustment control can be effectively carried out on the functions to be controlled based on the function adjustment information, the user does not need to adopt a touch control key to carry out function adjustment control on the functions to be controlled, operation of the user is further facilitated, and control experience of the user is improved.
