At present, automotive suspension systems are divided into two types, namely a passive suspension and an active suspension, wherein the traditional passive suspension fixes the damping characteristic of a shock absorber before a vehicle leaves a factory and is not adjustable, and an active suspension control system (namely a continuous shock absorption control system Continuous Damping Control, abbreviated as a CDC control system) can comprehensively judge according to different road conditions, emergency operation (acceleration/braking/steering) of a driver, real-time motion condition of the vehicle and the like, and adjust the damping force of the shock absorber in real time so as to realize riding comfort and steering stability.
In order to meet the requirements of drivers on different performances and different driving experiences of the vehicle, different driving modes including a sport mode, an economy mode, a comfort mode and a custom mode are configured on the vehicle. The driving mode selection modes are diversified, and each host factory has own characteristics, including various modes such as physical keys or knobs, meter or central control soft keys, physical keys and soft key combinations and the like. The control of the driving mode may be performed by combining various controls such as the power output characteristic of the engine or the motor, the steering assist control characteristic, the pedal assist control characteristic, the active suspension control characteristic, the energy recovery intensity characteristic, and the like so as to correspond to different driving modes.
In the existing active suspension control mode control scheme, the active suspension control characteristics are mostly corresponding to the driving mode, such as: the sport mode corresponds to the "hard" type active suspension control characteristic, the comfort mode corresponds to the "soft" type active suspension control characteristic, the economy mode corresponds to the "normal" type active suspension control characteristic, and the like.

In an embodiment of the present invention, after the vehicle is started, the control device may acquire, in real time, target condition information of a target road section of a current active suspension control mode of the vehicle; the method comprises the steps of acquiring a target historical active suspension control mode matched with target working condition information and a corresponding target historical vehicle attitude grade from historical data stored in a storage device or a cloud server according to the target working condition information, determining a first standby mode according to the occurrence times of the target historical active suspension control mode, determining a second standby mode according to the target historical vehicle attitude grade and a reference vehicle attitude grade, and adjusting the active suspension control mode of the vehicle according to a current mode adjustment strategy of the vehicle and at least one of the first standby mode and the second standby mode when at least one of the first standby mode and the second standby mode is different from the current active suspension control mode, wherein the mode adjustment strategy comprises the following steps: according to user preference, according to vehicle attitude class, and according to user selection. The method is convenient for users to actively switch to a more reasonable active suspension control mode or remind the users to switch to the more reasonable active suspension control mode when the users are not aware that the current active suspension control mode is unreasonable, and the vehicles can be timely switched to the active suspension control mode suitable for working conditions on the premise of not increasing other additional cost, so that the driving operability and riding comfort are ensured, the current problem that the users are required to subjectively control and switch the active suspension control mode and the vehicles have poor driving operability and riding comfort due to hysteresis is avoided.
Wherein the vehicle attitude level is used for representing the operability and smoothness of the vehicle when the vehicle is running, the vehicle attitude level is determined according to the vehicle state information in the invention, and the vehicle state information comprises but is not limited to: vertical acceleration of a vehicle body, vertical acceleration of wheels, pitch angle of the vehicle, yaw angle of the vehicle and the like. The vehicle posture grade may be expressed in the form of a number, or may be expressed in terms of excellent, good, poor, etc., and when expressed in terms of excellent, good, poor, etc., the excellent corresponding grade is greater than the good corresponding grade, and the good corresponding grade is greater than the poor corresponding grade.
Specifically, when a first standby mode is determined according to the occurrence times of the target historical active suspension control modes, counting the occurrence times of each historical active suspension control mode, and selecting the first standby mode with the largest occurrence times, wherein the occurrence times are the largest, when the user drives the vehicle to run under the working condition corresponding to the first working condition information, the target historical active suspension control mode is frequently used as the first standby mode, so that the user can select the corresponding active suspension control mode according to preference and habit, and the driving experience of the user is guaranteed;
when the second mode to be selected is determined according to the target historical vehicle attitude level and the reference vehicle attitude level, the vehicle attitude levels are ranked, a historical vehicle attitude level which is larger than or equal to any one of the first historical vehicle attitude levels and is larger than or equal to the reference vehicle attitude level is selected as the target vehicle attitude level, and the historical active suspension control mode corresponding to the target vehicle attitude level is determined to be the second mode to be selected, so that the comfort and the operability of the vehicle are ensured, and bad experience brought by the second preselected mode to a user is avoided.
Alternatively, on the basis of the present invention, those skilled in the art may set, according to actual situations, that a mode is to be switched to a certain mode or all modes without confirmation of a user, and thus the present invention is also within the scope of protection.
Specifically, the control method as described above, the step S103 of adjusting the current active suspension control mode according to at least one of the first candidate mode and the second candidate mode and the current mode adjustment strategy of the vehicle includes:
when the mode adjustment strategy is to adjust according to the preference of the user, if the first mode to be selected is different from the current active suspension control mode, switching to the first mode to be selected, and sending first mode switching information to the reminding device;
when the mode adjustment strategy is adjusted according to the vehicle attitude level, if the second mode to be selected is different from the current active suspension control mode, switching to the second mode to be selected, and sending second mode switching information to the reminding device;
when the mode adjustment strategy is adjusted according to the selection of the user, first mode switching reminding information comprising a first mode to be selected and/or a second mode to be selected which are different from the current active suspension control mode is sent to the reminding device, and the first mode to be selected or the second mode to be selected is switched to according to the received first confirmation switching signal.
In a specific embodiment of the present invention, when the current mode of the vehicle is the adjustment mode according to the preference of the user, if the first mode to be selected is different from the current active suspension control mode, it is determined that the current active suspension control mode is not the active driving mode commonly used by the user under the target working condition of the target road section, at this time, in order to better conform to the preference of the user, the active suspension control mode of the vehicle is automatically switched to the first mode to be selected, and the first mode switching information is sent to the reminding device to remind the user that the current active suspension control mode has been switched to the first mode to be selected, so that the user can accurately learn the active suspension control mode of the current vehicle.
When the current mode of the vehicle is the adjustment mode according to the vehicle posture grade, if the second mode to be selected is different from the current active suspension control mode, the current active suspension control mode is determined not to be the active suspension control mode with the best comfort and operability under the target working condition of the target road section, and at the moment, in order to enable the active suspension control mode of the vehicle to be more reasonable, the second mode is automatically switched to the second mode to be selected, and second mode switching information is sent to the reminding device, so that a user is reminded that the current active suspension control mode is switched to the second mode to be selected, and the user can accurately know the active suspension control mode of the current vehicle conveniently.
When the mode adjustment strategy is selected and adjusted according to a user, in order to facilitate the user to send first mode switching reminding information comprising a first mode to be selected and/or a second mode to be selected which are different from the current active suspension control mode to the reminding device when the current active suspension control mode is unreasonable, the user can conveniently select the active suspension control mode which is considered to be reasonable by the user to switch according to the situation of the user in time, and send a first confirmation selection signal to the control device, and when the control device receives the first confirmation switching signal, the control device switches to the first mode to be selected or the second mode to be selected by the user according to the information of the mode to be selected in the first confirmation switching signal.
Specifically, the reminding means for reminding when receiving the switching reminding information includes but is not limited to: one or more of text reminding, voice reminding, screen flicking reminding and the like.
Further, in the control method as described above, when the type of the history active suspension control mode corresponding to the target history vehicle posture level is plural, it is determined that the history active suspension control mode having the largest occurrence number is the second candidate mode.
In the invention, the mode with the largest occurrence number in the target historical active suspension control mode corresponding to the target vehicle attitude level is determined to be the second standby mode, and the second standby mode is ensured to be in line with the preference and habit of the user on the premise of ensuring the comfort and the operability brought by the second standby mode, so that the driving experience of the user is ensured.
Specifically, the control method as described above, when the vehicle is in the navigation state, the target link includes: the road section where the vehicle is currently located and the road section which does not run in the navigation information;
when the vehicle is in a non-navigation state, the target road section is the road section where the vehicle is currently located.
In a specific embodiment of the present invention, when the vehicle is in a navigation state or a non-navigation state, the road section where the vehicle is currently located is determined as the target road section, and the above control step of the active suspension control mode is further performed according to the target road section, so that when the user runs on the current road section where the current active suspension control mode is not matched with the working condition, the user can switch to the more reasonable active suspension control mode in time, and the problem of hysteresis when the current user switches the active suspension control mode is avoided.
When the vehicle is in a navigation state, the non-driving road section in the navigation information is determined as a target road section, and the control step of the active suspension control mode is further carried out according to the target road section, so that a user can know whether the current active suspension control mode is the working condition most suitable for the target road section or the mode most suitable for the preference and habit of the user before entering the target road section, the user has enough time to switch the active suspension control mode, and the user is further enabled to switch to the more reasonable active suspension control mode in advance when driving into the target road section, and driving experience of the user is guaranteed.
Further, in the control method as described above, when the target road section is a road section where the vehicle is currently located, the reference vehicle posture level is a current vehicle posture level determined according to the current vehicle state information;
when the target road section is a road section which does not run in the navigation information, the reference vehicle posture grade is a preset vehicle posture grade.
In another preferred embodiment of the present invention, when the target road section is the road section where the vehicle is currently located, in order to ensure that the comfort of the active suspension control mode recommended to be replaced by the control device is better, the judgment needs to be performed by taking the current vehicle posture grade as a standard, so that the vehicle posture grade corresponding to the active suspension control mode after switching is better than the current vehicle posture grade, which is beneficial to ensuring the driving comfort of the user. Meanwhile, the situation that the driving mode of the active suspension is switched frequently is avoided.
When the target road section is a road section which is not driven in the navigation information, in order to ensure that the switched active suspension control mode can provide good driving comfort for the user, the target historical vehicle posture level is required to be superior to a preset vehicle posture level preset by a user or a technician. Alternatively, the preset vehicle attitude level may be determined based on the current vehicle attitude level.
