In this embodiment, the starting condition for easy getting on and off can be specifically understood as a condition for judging whether the vehicle has a demand for getting on and off, so as to start the vehicle height adjustment function. The activation of the convenience of getting on and off the vehicle can be understood as the state of the automatic getting on and off enable switch of the vehicle being activated. The target user can be specifically understood as a user who needs to get on and off the vehicle, which can be a driver or a passenger. The target adjustment parameter can be specifically understood as a parameter used to adjust the height of the vehicle. The adjustment parameters corresponding to different users can be different. The target adjustment parameter can be 30mm, -40mm, etc., to realize the increase or decrease of the vehicle height.

Specifically, the adjustment parameters of different users are stored in advance, and the user can input the adjustment parameters by manual input. For example, the adjustment parameters are set through the display screen of the vehicle, and the setting of the convenient function of getting on and off is realized through human-computer interaction.

Exemplarily, FIG. 2 provides a display example diagram of a human-computer interaction interface. As shown in FIG. 2, 4 layers of functions are designed in the human-computer interaction interface. 2-Suspension"-"Function level 3-Easy to get on and off"-"Function level 4-Easy to get on and off the enable switch activation/deactivation, adjustment parameter setting method", in which, when setting the adjustment parameters, different drivers can set The corresponding adjustment parameters are convenient for getting on and off by yourself. Drivers can access deeper functions with larger levels by clicking buttons with lower levels. In function level 4, there is an on/off button for the air suspension system to facilitate getting on and off, and a button for setting different adjustment parameters. When the enable switch is ON, it means that the convenient getting on and off function is activated, and the vehicle height can be adjusted automatically; when the enabling switch is OFF, it means that the convenient getting on and off function is disabled, and the vehicle height cannot be adjusted.

When the vehicle is stationary, the user can manually input the adjustment parameter h1 by clicking the "parameter 1" button on the left, and it will be automatically saved and memorized in the vehicle's register after XX seconds. The adjustment parameters suitable for different users can be obtained through multiple attempts of lifting and lowering Parameters that match height. The setting methods of the adjustment parameters h2 and h3 are the same, and are not repeated here. Long press "user 1" to modify the user name corresponding to "adjustment parameter h1", such as "hostess", which will be automatically saved and memorized in the vehicle's register after XX seconds. The setting method of "User 2" and "User 3" is the same as that of "User 1". When setting the adjustment parameters, the upper and lower limits of the adjustment parameters can be set according to the actual conditions of different vehicles.

Following the above description, when it is detected that the user needs to get on or off the vehicle, it is determined that the vehicle satisfies the conditions for enabling easy getting on and off, and at the same time, it is determined whether the enabling switch for easy getting on and off of the vehicle is activated. , then it is determined that the vehicle's convenience for getting on and off is activated, and by identifying each user on the vehicle, the target user who has the need to get on and off is determined at this time, and at the same time, by querying the pre-stored adjustment parameters of each user, the corresponding target user is determined. target adjustment parameters. When the boarding enable is not activated, the vehicle height cannot be adjusted even if the conditions for easy getting on and off are met. At this time, the driver or other passengers can be prompted to turn on the easy boarding enable switch through voice, text, pictures, etc.

Optionally, the starting conditions for the convenient getting on and off include at least one of the following: the seat belt is pulled out and the door corresponding to the seat is opened, the ignition switch of the vehicle is turned off, and the triggering information of the convenient getting on and off function input by the user is received.

S102: Acquire first state information of the vehicle, and if it is determined according to the first state information that the vehicle satisfies the activation condition of the convenient getting on and off function, determine the first target damping force.

In this embodiment, the first state information may be information used to indicate the current state of the vehicle, for example, the speed of the vehicle, the state of each control system in the vehicle (whether it is faulty), the current gear of the vehicle, and the like. The starting condition of the convenient getting on and off function can be specifically understood as a condition for judging whether the vehicle currently starts to automatically adjust the vehicle height when getting on and off. The first target damping force can be specifically understood as the damping force used to adjust the shock absorber, and the first target damping force is less than the original damping force of the shock absorber; the original damping force can be specifically understood as the shock absorber before the vehicle height adjustment is performed. damping force.

Specifically, the first state information of the vehicle is acquired, the state of the vehicle is analyzed according to the first state information, and it is determined whether the vehicle satisfies the activation condition of the convenient function of getting on and off, and when it is determined that the vehicle meets the activation condition of the convenient function of getting on and off, the first target is determined Damping force to ensure that the first target damping force is smaller than the original damping force of the shock absorber of the vehicle. For example, the damping force of the shock absorber at the current moment is obtained as the original damping force, and the smaller damping force is selected as the first damping force according to the original damping force. A target damping force. When the vehicle does not meet the activation conditions of the convenient getting on and off function, at this time, the user can be prompted by voice, text, etc. that does not meet the activation conditions of the convenient getting on and off function, and at the same time, it can also prompt the user that the adjustment fails.

The vehicle is in the parking state, that is, the vehicle is in the P position. The failure of the system may mean that the entire vehicle control system of the vehicle or each system in the vehicle is faultless, or the control system used for vehicle height adjustment in the vehicle is faultless, for example, the air suspension system is faultless.

S103: Adjust the shock absorber of the vehicle according to the first target damping force, and adjust the height of the vehicle according to the target adjustment parameter.

The shock absorber in the embodiment of the present application may be a continuous damping adjustable shock absorber, an active shock absorber, an electromagnetic shock absorber, a two-stage electronically controlled shock absorber, or the like.

Specifically, to adjust the damping force of the shock absorber according to the first target damping force, the shock absorber may be directly adjusted to the first target damping force, or the damping force of the shock absorber may be gradually adjusted according to a certain step size to the first target damping force. Determine the height that the vehicle needs to be adjusted according to the target adjustment parameters, or how high the vehicle needs to be adjusted, and further adjust the vehicle height according to the target adjustment parameters. Or the active stabilizer bar, etc., to replace the components that realize the function of vehicle height adjustment. The working principle of the air suspension vehicle height adjustment is to charge and release the air spring to realize the vehicle height adjustment. Active suspension and hydraulic suspension use hydraulic pressure to push the piston rod of the shock absorber to move up and down to achieve the purpose of height adjustment. The active stabilizer bar is driven by the motor to lift and lower both ends of the stabilizer bar to realize the change of vehicle height. After the shock absorber is adjusted to the first target damping force, its damping force is reduced. When the vehicle height is adjusted, the hindering effect of the shock absorber is reduced, thereby increasing the adjustment speed.

An embodiment of the present application provides a vehicle height adjustment method. When it is detected that the vehicle meets the starting conditions for easy getting on and off and the enabling easy getting on and off is activated, a target user and target adjustment parameters of the target user are determined; First state information, if it is determined according to the first state information that the vehicle satisfies the activation condition of the convenient function of getting on and off, a first target damping force is determined, wherein the first target damping force is smaller than the shock absorber of the vehicle. The original damping force; the shock absorber of the vehicle is adjusted according to the first target damping force, and the height of the vehicle is adjusted according to the target adjustment parameter.

Different users can set corresponding adjustment parameters according to actual needs. When adjusting, they can adjust different heights for different users to achieve personalized settings. Meet the needs of different users, improve user experience, and adjust the shock absorber through the first target damping force. Since the first target damping force is smaller than the original damping force of the shock absorber, the adjustment of the damping force of the shock absorber is reduced. The hindering effect increases the adjustment speed.

Embodiment 2

S201. When it is detected that the vehicle satisfies the start condition for easy getting on and off and the enabling easy getting on and off is activated, receive user identification information input by a user and/or collect user image information.

In this embodiment, the user identification information can be specifically understood as information used to identify the user's identity, for example, the user's ID, name, etc., the user's ID, name, etc. are correspondingly input or automatically generated when inputting adjustment parameters, and the user's fingerprint and many more. The user image information can be specifically understood as the information including the user image. The user image can be an image that only includes the user's face, or an image that includes the user's upper body. The user image information in this application can be the abstract information of the image. Letters are often irreversible and cannot be traced back to the original image.

After it is detected that the vehicle satisfies the conditions for enabling easy getting on and off and the enabling easy getting on and off is activated, the user identification information input by the user manually or by voice is received. For example, the user can select the user's Name, ID, etc., or the user inputs the user's name, ID, etc. through voice to realize the input of user identification information. At the same time, an image acquisition device can also be set on the vehicle to collect user image information. One or more image capturing devices may be provided, for example, in front of the seat, so that the captured images can accurately identify the user. After the image collection device collects the user image, it can use the summary information of the image as the user image information, and delete the original collected image.

By analyzing the user identification information and matching with pre-stored users, the matching target users are determined. Or perform image processing on the user's image information, identify whether the user has the intention to get on and off the vehicle through image processing, determine the image including the user with the intention to get on and off, identify, match with the pre-stored user, and determine the matching target user. . Or use the above two methods to identify the target user at the same time. If the results of the two identification methods are different, determine which result prevails according to the preset priority, or prompt the user to re-input and re-collect.

S203: Determine the target adjustment parameter corresponding to the target user according to the target user querying the predetermined parameter table.

In this embodiment, the parameter table can be specifically understood as a data table corresponding to storing different users and their adjustment parameters. The parameter table is pre-determined, that is, the parameter table is generated according to the adjustment parameters, user name and other data input by the user.

S205. Determine the first target height according to the target adjustment parameter.

In this embodiment, the first target height can be specifically understood as the adjusted height of the vehicle. If the target adjustment parameter is an adjusted height, for example, 30 mm, the first target height is determined according to the adjustment parameter and the current height of the vehicle. If the target adjustment parameter is the adjusted height, the target adjustment parameter is directly used as the first target height.

S206. Generate a first control command according to the first target height, and control the front axle and the rear axle of the vehicle according to the first control command until the vehicle height is adjusted to the first target height.

In this embodiment, the first control instruction can be specifically understood as a computer instruction for controlling the height of the vehicle. The first control command is generated according to the first target height, and the first control instructs the vehicle to execute the work of the actuator related to the vehicle height adjustment, so as to realize the adjustment of the vehicle height until the height of the vehicle is adjusted to the first target height.

Exemplarily, taking the control of the height of the vehicle through the air suspension system as an example, the air suspension system is controlled through the first control command, so that the air suspension system controls the front axle and the rear axle of the vehicle, and the air suspension system controls the front and rear axles of the vehicle. Under the control of the command, open the valve to deflate or open the valve to inflate, reduce the vehicle height or increase the vehicle height. In the process of vehicle height adjustment, the front and rear axles of the vehicle are controlled to adjust the height by opening the solenoid valves corresponding to the 4 air springs in the gas distribution valve and controlling the exhaust valve in the compressor to inflate or deflate.

Preferably, when lowering the vehicle height, the front axle is lowered first, and then the rear axle is lowered alternately. For example, in the process of lowering the vehicle height, the height sensor detects whether the vehicle height at the front of the vehicle is adjusted to the first target height. After adjusting to the first target height, continue to adjust the rear axle so that the rear of the vehicle is adjusted to the first target height. high. When raising the vehicle height, the rear axle is raised first, and then the front axle is raised alternately. The process is similar to the process of lowering the vehicle height, and will not be repeated here.

The gas storage tank 311 is electrically connected to the pipeline 312 physically. If the air suspension controller 303 does not contain inertial navigation, the acceleration of the vehicle body can be collected by installing an acceleration sensor on the vehicle body, and its implementation function is the same as that of inertial navigation. The number of acceleration sensors is usually 3-4.

S207. Restore the damping force of the shock absorber of the vehicle from the first target damping force to the original damping force.
