As shown in fig. 1, the method includes:
s101, when the fact that the vehicle meets the starting condition for facilitating getting on and off of the vehicle and enables activation for facilitating getting on and off of the vehicle is detected, a target user and target adjusting parameters of the target user are determined.
In this embodiment, the starting condition for facilitating getting on and off of the vehicle may be specifically understood as a condition for determining whether the vehicle has a need to get on or off the vehicle to start the vehicle height adjusting function. Facilitating the getting on and off enable activation may be understood as the state of an automatic getting on and off enable switch of the vehicle being activated. The target user may be specifically understood as a user having a need to get on or off the vehicle, which may be a driver or a passenger. The target adjusting parameter can be specifically understood as a parameter for adjusting the height of the vehicle, the adjusting parameters corresponding to different users can be different, and the target adjusting parameter can be 30mm, -40mm, and the like, so that the height of the vehicle can be adjusted up or down.
Specifically, the adjustment parameters of different users are stored in advance, and the users can input the adjustment parameters in a manual input mode. For example, adjusting parameters are set through a display screen of the vehicle, and the function of conveniently getting on and off the vehicle is set through human-computer interaction.
For example, fig. 2 provides an illustration of a human-computer interaction interface, and as shown in fig. 2, a 4-layer function is designed on the human-computer interaction interface, and from outside to inside, the functions are respectively 'function level 1-vehicle-' function level 2-suspension- 'function level 3-convenient getting on and off-function level 4-convenient getting on and off-function enabling switch activation/off and parameter adjustment setting method', wherein when setting adjustment parameters, different drivers can set corresponding adjustment parameters to facilitate getting on and off the vehicle by themselves. The driver can enter a deeper function with a larger number of levels by clicking a button with a smaller number of levels. There are on/off buttons in the functional level 4 for the air suspension system to facilitate the getting on and off functions, and different adjustment parameter setting buttons. When the enable switch is ON, the convenient getting ON/off function is activated, and the vehicle height of the vehicle can be automatically adjusted; when the enable switch is OFF, the convenient getting on/OFF function is turned OFF, and the vehicle height cannot be adjusted.
When the vehicle is at rest, a user can manually input an adjusting parameter h1 by clicking a left parameter 1 button, the adjusting parameter is automatically stored and memorized in a register of the vehicle after XX seconds, and the adjusting parameters suitable for different users can obtain parameters matched with the height through multiple lifting attempts. The setting methods of the adjusting parameters h2 and h3 are the same, and are not described in detail herein. The user name corresponding to the adjusting parameter h1, such as "owner of a woman", can be modified by pressing "Userai 1", and is automatically saved and memorized in a register of the vehicle after XX seconds. The setting methods of "user 2" and "user 3" are the same as those of "user 1". When the adjusting parameters are set, the upper limit and the lower limit of the adjusting parameters can be set according to the actual conditions of different vehicles.
According to the description, when the fact that a user needs to get on or off the vehicle is detected, it is determined that the vehicle meets the starting condition for facilitating getting on or off the vehicle, whether a enabling switch for facilitating getting on or off the vehicle of the vehicle is activated or not is judged, if the enabling switch for facilitating getting on or off the vehicle of the vehicle is activated, enabling activation for facilitating getting on or off the vehicle of the vehicle is determined, a target user with getting on or off the vehicle at the moment is judged by identifying each user on the vehicle, and meanwhile, target adjusting parameters corresponding to the target user are determined by inquiring pre-stored adjusting parameters of each user. When the getting-on enabling is not activated, even if the starting condition for facilitating getting-on and getting-off is met, the height of the vehicle cannot be adjusted, and at the moment, a driver or other passengers can be prompted to turn on the enabling switch for facilitating getting-on and getting-off through the forms of voice, characters, pictures and the like.
Optionally, the starting condition for facilitating getting on or off the vehicle includes at least one of the following conditions: the seat belt is pulled out, the door corresponding to the seat is opened, the ignition switch of the vehicle is closed, and the function triggering information which is input by a user and is convenient for getting on or off the vehicle is received.
In this embodiment, the information for triggering the function of conveniently getting on/off the vehicle may be specifically understood as information for triggering the function of automatically adjusting conveniently getting on/off the vehicle.

S102, first state information of the vehicle is obtained, and if the vehicle is determined to meet starting conditions of functions facilitating getting on and off of the vehicle according to the first state information, a first target damping force is determined.
In the present embodiment, the first state information may be information indicating the current state of the vehicle, such as the speed of the vehicle, the state of each control system in the vehicle (whether there is a malfunction), the gear in which the vehicle is currently located, and the like. The starting condition of the function of conveniently getting on and off the vehicle can be specifically understood as a condition for judging whether the vehicle is currently started to get on and off the vehicle and automatically adjust the height of the vehicle. The first target damping force may be understood in particular as a damping force for adjusting the shock absorber, the first target damping force being smaller than the original damping force of the shock absorber; the original damping force can be understood in particular as the damping force of the shock absorber before the vehicle height adjustment is not performed.
Specifically, first state information of the vehicle is acquired, the state of the vehicle is analyzed according to the first state information, whether the vehicle meets a starting condition of a function of facilitating getting on and off the vehicle is judged, when it is determined that the vehicle meets the starting condition of the function of facilitating getting on and off the vehicle, a first target damping force is determined, the first target damping force is ensured to be smaller than an original damping force of a shock absorber of the vehicle, for example, the damping force of the shock absorber at the current moment is acquired to serve as the original damping force, and the smaller damping force is selected to serve as the first target damping force according to the original damping force. When the vehicle does not meet the starting condition of the function of conveniently getting on or off the vehicle, the user can be prompted in modes of voice, characters and the like to fail to meet the starting condition of the function of conveniently getting on or off the vehicle, and meanwhile, the user can be prompted to fail to adjust. When the vehicle does not meet the starting condition of the function of conveniently getting on and off the vehicle, the adjustment can be directly finished, and the adjustment can also be waited until the vehicle meets the starting condition of the function of conveniently getting on and off the vehicle, or the starting condition of the function of conveniently getting on and off the vehicle is still not met after waiting for a period of time, and the adjustment is finished.
Optionally, the starting conditions of the function of conveniently getting on and off the vehicle are that the vehicle is static, the system has no fault and the vehicle is in a parking state.
The vehicle is in a parking state, i.e., the vehicle is in P range. The system failure may be that the entire vehicle control system or each system in the vehicle has no failure, or that the control system for vehicle height adjustment in the vehicle has no failure, for example, that the air suspension system has no failure.
S103, adjusting the shock absorber of the vehicle according to the first target damping force, and adjusting the vehicle height of the vehicle according to the target adjusting parameter.
The shock absorber in the embodiment of the application can be a continuous damping adjustable shock absorber, an active shock absorber, an electromagnetic shock absorber, a two-section type electronic control shock absorber and the like.
Specifically, the damping force of the shock absorber is adjusted according to the first target damping force, which may be directly adjusted to the first target damping force, or may be gradually adjusted to the first target damping force according to a certain step length. The height of the vehicle required to be adjusted is determined according to the target adjusting parameters, or the height of the vehicle required to be adjusted is determined, the vehicle height of the vehicle is further adjusted according to the target adjusting parameters, and the vehicle height can be adjusted through an air suspension system, an active suspension, a hydraulic suspension or an active stabilizer bar and the like, so that the components with the vehicle height adjusting function can be replaced. The working principle of the air suspension vehicle height adjustment is to fill and deflate an air spring to realize vehicle height adjustment. The active suspension and the hydraulic suspension push a piston rod of the shock absorber to move up and down through hydraulic pressure so as to achieve the purpose of height adjustment. The driving stabilizer bar realizes the change of the vehicle height by driving the two ends of the stabilizer bar to lift and descend through a motor. After the shock absorber is adjusted to the first target damping force, the damping force of the shock absorber is reduced, and when the vehicle height is adjusted, the blocking effect of the shock absorber is reduced, so that the adjusting speed is increased.
The embodiment of the application provides a vehicle height adjusting method, which comprises the steps of determining a target user and target adjusting parameters of the target user when detecting that a vehicle meets starting conditions for facilitating getting on and off and enables activation for facilitating getting on and off; acquiring first state information of a vehicle, and determining a first target damping force if the vehicle meets a starting condition of a function of conveniently getting on or off the vehicle according to the first state information, wherein the first target damping force is smaller than an original damping force of a shock absorber of the vehicle; and adjusting the shock absorber of the vehicle according to the first target damping force, and adjusting the vehicle height of the vehicle according to the target adjustment parameter. The problem of only can adjust to fixed first target height in the altitude mixture control process of vehicle is solved, different users can set up corresponding adjusting parameter according to actual demand, can adjust different height for different users when adjusting, realize individualized setting, satisfy different user's demand, improve user experience, and, adjust the shock absorber through first target damping force, because first target damping force is less than the original damping force of shock absorber, reduced the hindrance effect of the damping force of shock absorber to the regulation, improved governing speed.
