All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flowchart of a control method of an active suspension of a vehicle according to an embodiment of the present invention, which is applicable to an active suspension control unit provided in a target vehicle, as shown in fig. 1, and includes the steps of:
s102, when it is monitored that the target vehicle runs on a preset target running road section, first suspension parameter information of each wheel of the target vehicle on the target running road section is obtained.
The first suspension parameter information is calculated according to first road information corresponding to a target driving road section acquired in advance, and the first suspension parameter information calculated in advance can be stored in a vehicle storage unit built in the target vehicle in advance. The first road information may include road height, road spectrum, etc., and the first suspension parameter information may include suspension stiffness, suspension damping, etc.
The method for acquiring the first road information corresponding to the target travel section may be: first, a target travel section of a target vehicle is determined, which can be determined by monitoring an application having a trip creation function, for example, when it is monitored that new trip information is created in a calendar, the target travel section can be determined according to the trip information. The determination time of the target driving road section is not limited, and only needs to be determined before the target vehicle drives, for example, the target driving road section can be determined immediately after the travel information is monitored, and the target driving road section can also be determined within a preset time before the target vehicle starts. And secondly, acquiring a digital electronic road map corresponding to the target driving road section from the network side, wherein the acquired digital electronic road map can be stored in a vehicle storage unit in advance, and the next step can be executed immediately when the acquired digital electronic road map is acquired. And thirdly, analyzing the digital electronic road map corresponding to the target driving road section prestored in the vehicle storage unit to determine first road information corresponding to the target driving road section.
When the first suspension parameter information is calculated according to the first road surface information, the first suspension parameter information can be obtained by calculating the road surface height, the road spectrum and other information in the first road surface information through a control algorithm. The control algorithm includes, but is not limited to, a suspension adaptive control algorithm, a suspension fuzzy control algorithm, a neural network control algorithm and the like, and the first suspension parameter information can also be calculated through fusion of a plurality of control algorithms to achieve a more accurate calculation result. The above-mentioned several control algorithms belong to the prior art, and the specific implementation process of each algorithm is not described herein.
And S104, determining first running state information of the target vehicle.
The first driving state information may include information such as a steering wheel angle, a steering wheel torque, a lateral acceleration, a longitudinal acceleration, and a vehicle speed. Various items of information may be collected by sensors installed inside the subject vehicle. For example, the steering wheel angle can be acquired by a steering wheel angle sensor; the steering wheel torque can be acquired through a steering wheel torque sensor; the transverse acceleration and the longitudinal acceleration can be acquired by a yaw angular velocity sensor; the vehicle speed can be acquired by a vehicle speed sensor.
In this embodiment, when the target vehicle travels on the target travel section, the first travel state information of the target vehicle is not constant, and the first travel state information of the target vehicle changes when there are situations such as passing a vehicle ahead, changing lanes, and sudden braking.
And S106, determining a first suspension parameter correction strategy of each wheel on the target driving road section according to the first driving state information of the target vehicle.
In this embodiment, since the first driving state information of the target vehicle may cause different loads borne by each wheel, it is necessary to determine, for each wheel, a first suspension parameter correction strategy of each wheel on the target driving section, so that the active suspension control effect of the target vehicle is more accurate.
The first suspension parameter modification strategy may include increasing or decreasing the suspension parameter for each wheel.
S108, correcting the first suspension parameter information according to the first suspension parameter correction strategy to obtain second suspension parameter information; and adjusting the suspension parameters of each wheel according to the second suspension parameter information.
By adopting the technical scheme of the embodiment of the invention, when the situation that the target vehicle runs on the preset target running road section is monitored, the first suspension parameter information (comprising suspension rigidity and/or suspension damping) of each wheel on the target running road section is obtained through pre-calculation, the first running state information of the target vehicle is determined, the first suspension parameter correction strategy of each wheel on the target running road section is further determined according to the first running state information, the first suspension parameter information is corrected according to the first suspension parameter correction strategy, the second suspension parameter information is obtained, and the suspension parameters of each wheel are further adjusted according to the second suspension parameter information. Therefore, according to the technical scheme, the calculated amount of the target vehicle in the running process is greatly reduced by calculating the suspension parameter information of the target vehicle in advance, so that the suspension parameters of each wheel can be quickly adjusted, and the reaction speed of the suspension is improved. In addition, the suspension parameter information of each wheel can be corrected according to the running state information of the target vehicle, so that the corrected suspension parameter information is matched with the running state of the target vehicle, the accuracy of suspension parameter adjustment is improved, and the riding comfort of a user is improved.
In one embodiment, to improve the accuracy of suspension parameter adjustments, the road surface information may be analyzed in segments. Therefore, the following method can be adopted to obtain the first road surface information of the target driving road section where the target vehicle is located in advance, and then calculate the first suspension parameter information:
firstly, a target driving section of a target vehicle is determined, and a digital electronic road map corresponding to the target driving section is obtained from a network side.
And secondly, analyzing the digital electronic road map of the target driving road section, and determining first road information corresponding to the target driving road section.
And thirdly, segmenting the first road information corresponding to the target driving road section according to the preset unit road section length to obtain a plurality of sub road sections.
The sub-road sections respectively correspond to respective road surface information, and the value of the unit road section length can be set according to actual requirements, such as 5 km.
And finally, calculating first suspension parameter information corresponding to each sub-road section according to the road surface information corresponding to each sub-road section.
In this step, the first suspension parameter information corresponding to each sub-segment may be stored in advance in a vehicle storage unit built in the target vehicle. When it is monitored that the target vehicle runs on a preset target running road section, first suspension parameter information of the corresponding sub-road section is obtained according to the running road section of the target vehicle. For example, assuming that the target vehicle is currently traveling within the sub-link a on the target traveling link, the first suspension parameter information corresponding to the sub-link a may be acquired from the vehicle storage unit, and preferably, the first suspension parameter information corresponding to the sub-link a may be acquired before the target vehicle travels into the sub-link a.
In this embodiment, the first suspension parameter information corresponding to each sub-road section is calculated in a segmented manner, so that the first suspension parameter information of the corresponding sub-road section can be subsequently acquired according to the traveling road section of the target vehicle, and therefore the suspension parameters of each wheel of the target vehicle can be adjusted more accurately.
In this embodiment, assuming that the target vehicle travels in the sub-road segment a on the target travel road segment and the first suspension parameter information corresponding to the sub-road segment a has been acquired from the vehicle storage unit, the first suspension parameter information corresponding to the sub-road segment a acquired by the vehicle storage unit may also be deleted when the target vehicle exits the sub-road segment a (e.g., enters the sub-road segment B after the sub-road segment a), thereby saving the storage space of the vehicle storage unit.
In one embodiment, before determining the first driving state information of the target vehicle, it may be determined whether the actual road information corresponding to the target driving section acquired in real time is consistent with the first road information corresponding to the target driving section acquired in advance, and the subsequent operation may be determined based on whether the actual road information is consistent with the first road information.
Based on the method, the second road information (namely the actual road information) corresponding to the target driving road section can be collected in real time in the driving process of the target vehicle, and whether the second road information is consistent with the first road information or not can be judged in real time. If yes, S104 is continuously executed, i.e., the first driving state information of the target vehicle is determined. The second road information includes information such as road height (i.e., a correspondence table between different geographic coordinate positions and the road height at the position), road spectrum (road spectrum, which refers to road spectrum for short, and power spectral density curve of road unevenness).
In this embodiment, in the driving process of the target vehicle, the second road surface information corresponding to the target driving road section may be collected in real time by using a vehicle-mounted camera and/or a laser radar installed in the target vehicle. Wherein, in order to ensure road surface information acquisition's accuracy, on-vehicle camera or laser radar can install in higher position, like the roof. The types and the use methods of the vehicle-mounted camera and the laser radar are not limited in the present application.
For example, the three-dimensional laser radar sensor is used for acquiring second road surface information corresponding to the target driving road section in real time, and if the second road surface information comprises the actual road surface height, the actual road surface height can be compared with the road surface height in the first road surface information, so that whether the actual road surface height and the road surface height are consistent or not can be judged. In one embodiment, a comparison threshold may be set for whether the road surface heights are consistent, and if the comparison threshold is 1 cm, it is determined that the second road surface information is consistent with the first road surface information when the difference between the actual road surface height and the road surface height in the first road surface information is not more than 1 cm.
In one embodiment, after the second road information is judged to be consistent with the first road information, a first suspension parameter correction strategy of each wheel on the target driving road section is determined according to the first driving state information, and load information and road impact information of a suspension corresponding to each wheel are respectively determined according to the first driving state information; and secondly, determining a correction strategy of the suspension stiffness corresponding to each wheel according to the load information, and determining a correction strategy of the suspension damping corresponding to each wheel according to the road surface impact information.
In one embodiment, only one of the load information or the road surface impact information of the suspension corresponding to each wheel may be acquired, and then the correction strategy of the suspension parameter corresponding to each wheel may be determined according to the load information or the road surface impact information.
In one embodiment, if the second route information and the first route information are not consistent, the following steps a1-A3 may be performed:
step a1, the vehicle speed of the target vehicle is controlled and adjusted according to the second road surface information.
In this step, a vehicle speed adjustment mode for the target vehicle may be determined according to the second road surface information, where the vehicle speed adjustment mode includes a vehicle speed adjustment value, a vehicle speed adjustment direction (such as adjusting the vehicle speed up or down), and the like; and controlling the speed of the target vehicle to correspondingly adjust according to the speed adjusting mode.
The vehicle speed adjusting value can be a vehicle speed adjusting percentage, a vehicle speed adjusting amplitude or a vehicle speed adjusting target value and the like. For example, if the vehicle speed adjustment value is 60% of the vehicle speed adjustment percentage, the vehicle speed is adjusted to 60% of the original vehicle speed according to the vehicle speed adjustment direction after the vehicle speed adjustment direction of the target vehicle at a certain time is determined. For another example, if the vehicle speed adjustment value is a target vehicle speed adjustment value of 60km/h, the vehicle speed can be adjusted from the original vehicle speed of 80km/h to 60km/h according to the vehicle speed adjustment direction after the vehicle speed adjustment direction is determined.
Step A2, calculating third suspension parameter information of each wheel on the target driving road section according to the second road surface information; and determining second driving state information of the target vehicle; and determining a second suspension parameter correction strategy of each wheel on the target driving section according to the second driving state information.
In this embodiment, if the second road information is not consistent with the first road information, the suspension parameter information may be recalculated according to the second road information collected in real time without using the first suspension parameter information calculated in advance.
Wherein the second road surface information may be analyzed and the third suspension parameter information may be calculated according to the method of calculating the first suspension parameter in S102.
The second driving state information may include information of a steering wheel angle, a steering wheel torque, a lateral acceleration, a longitudinal acceleration, a vehicle speed, and the like; the third suspension parameter information may include suspension stiffness and suspension damping, or one of suspension stiffness and suspension damping. The second driving state information of the target vehicle may be acquired by a sensor installed inside the target vehicle. For example, the steering wheel angle can be acquired by a steering wheel angle sensor; the steering wheel torque can be acquired through a steering wheel torque sensor; the transverse acceleration and the longitudinal acceleration can be acquired by a yaw angular velocity sensor; the vehicle speed can be acquired by a vehicle speed sensor.
In the step, load information and road surface impact information corresponding to each wheel can be determined through the second running state information, and then a second suspension parameter correction strategy of each wheel on the target running section is determined.
Step A3, correcting the third suspension parameter information according to the second suspension parameter correction strategy to obtain fourth suspension parameter information; and adjusting the suspension parameters of each wheel according to the fourth suspension parameter information.
The second suspension parameter modification strategy may include increasing or decreasing the suspension parameter for each wheel.
When the target vehicle travels on the target travel section, the actual road surface information may be different from the first road surface information acquired in advance due to road repair, road obstacle, or the like, and the travel state information of the target vehicle may also be changed. For this situation, in the present embodiment, the suspension parameter information of each wheel can be recalculated according to the actual road surface information, the second suspension parameter modification strategy of each wheel on the target driving section is determined according to the second driving state information of the target vehicle, and then the recalculated third suspension parameter information is modified according to the second suspension parameter modification strategy, so that the suspension parameter of each wheel of the target vehicle can be comprehensively considered based on the actual road surface information and the driving state information of the target vehicle, thereby further ensuring the accuracy of adjusting the suspension parameter of each wheel, and improving the comfort of the user in riding.
