The above embodiments respectively describe the application of the technical solution of the present application to an automobile capable of automatically adjusting suspension and a roadside unit, and the following embodiments describe the application of the technical solution of the present application to an automobile capable of automatically adjusting suspension and a roadside unit together, where a suspension height adjusting system is a system for realizing automatic suspension adjustment of an automobile, please refer to fig. 3, which includes:
301. and the suspension height adjusting system configures and stores mapping relations between different flatness levels and different suspension heights.
The automobile of the embodiment of the application needs to be configured in advance in the suspension height adjusting system and store mapping relations between different flatness grades and different suspension heights. Because the adjustable suspension heights of different types of automobiles are different, and the adjustment suspension modes of automobiles with different suspension structure forms are also different, in view of this, the automobiles need to be configured with the mapping relationship between the flatness grade suitable for the automobiles and the corresponding suspension heights.
For example, the adjustable height of the current automobile when the automobile is hung at the default position is positive 15 cm, and the lowest point of the automobile chassis is X cm away from the ground; and the flatness grade corresponding to the roadside unit is divided into three grades, the height of the first flatness grade is within X cm, the height of the second flatness grade is between X cm and (X +15) cm, the height of the third flatness grade is greater than (X +15) cm, at the moment, a suspension adjusting height of plus 0 cm is configured to be correspondingly mapped to the first flatness grade, a suspension adjusting height of plus 15 cm is configured to be correspondingly mapped to the second flatness grade, and a suspension adjusting height of plus 15 cm is configured to be correspondingly mapped to the third flatness grade and simultaneously prompt dangerous obstacle information (the suspension height limit of the current automobile is not enough to span the obstacle). Therefore, when the road flatness information shared by the current automobile by the road side unit reflects that the height of the road obstacle is the first flatness grade, the suspension default height of the current automobile can meet the requirement that the automobile chassis passes safely; when the road flatness information shared by the current automobile by the road side unit reflects that the height of the road obstacle is in a second flatness grade, the suspension default height of the current automobile cannot meet the requirement of safe passing of an automobile chassis, and the suspension height needs to be adjusted; and when the road side unit reflects that the road barrier height is the third flatness grade in the road flatness information shared by the current automobile, the highest suspension height of the current automobile cannot meet the requirement of safe passing of an automobile chassis, and at the moment, the suspension height needs to be adjusted to be the highest, so that the probability of collision between the automobile and the barrier is reduced as much as possible, and dangerous barrier information is prompted (the limit of the suspension height of the current automobile is not enough to cross the barrier).
302. The suspension height adjustment system monitors the current position of the vehicle.
The execution of this step is similar to the operation of step 101 in fig. 1, and will not be described again here.
303. The suspension height adjustment system collects current road flatness information for the road on which the vehicle is traveling.
It will be appreciated that the suspension height adjustment system of each vehicle may gather current road flatness information for the current road on which the vehicle is traveling by mounting sensors (vision, ultrasound, etc.). Therefore, the automobile passenger transport can complete the acquisition of the current road flatness information of the road surface through the sensor of the automobile passenger transport.
304. The suspension height adjusting system sends current automobile state information to the road side unit, wherein the current automobile state information comprises a current position, a unique identifier and current road flatness information; the road side unit receives the current vehicle state information.
The suspension height adjusting system of the automobile periodically and actively reports the current automobile state information to the road side unit system, wherein the current automobile state information at least comprises a current position and a unique identifier. The unique identification is used for the road side unit system to identify the identity of the current automobile, and the current position is used for the road side unit system to quickly identify the specific position of the current automobile, so that the road side unit system can identify and monitor the distance for more automobiles. The car height suspension system also uploads the current road flatness information of the traveled road collected by the car height suspension system per se in step 303 to the road side unit, so that the road side unit can acquire the latest road state information.
305. The road side unit system acquires road flatness information of a road, wherein the road flatness information comprises a specific position and a flatness grade of the road.
The execution of this step is similar to the operation of step 201 in the embodiment of fig. 2, and is not described again here.
For example, if the roadside unit is built around a certain road, the embodiment may also directly install a corresponding sensor (optical, ultrasonic, etc.) on the roadside unit to directly acquire the road flatness information from the road.
306. The road side unit updates the road flatness information by receiving the current road flatness information sent by the automobile.
Generally, the flatness information of the current road uploaded to the roadside unit by the vehicle on the current driving road better conforms to the actual state of the specific position of the rough road than the flatness information of the road already stored by the roadside unit, and after the flatness information of the road is obtained in step 305, the flatness information of the road can be updated by using the flatness information of the current road to obtain the latest flatness information of the road, so that the flatness information of the road is more accurate.
307. The road side unit judges whether the distance value between the current position and the specific road position is equal to or lower than a second preset distance threshold, if so, the step 310 is executed; if the distance between the current position and the specific road position exceeds the second preset distance threshold, step 304 is executed.
The execution of this step is similar to the operation of step 203 in the embodiment of fig. 2, and is not repeated here.
308. The road side unit system judges whether the road flatness information is sent to the automobile or not through the unique identifier, and if the road flatness information is sent to the automobile, step 309 is executed; if the road flatness information is not sent to the car, step 310 is executed.
In the step, the road side unit system further judges whether the road flatness information is sent to the automobile or not through the unique identifier uploaded by the automobile, so that the condition that the same road flatness information is sent to the same automobile repeatedly is avoided, the resource waste is reduced, and the service reliability is improved.
309. And stopping sending the road flatness information to the automobile.
If it is determined in step 308 that the flatness information of a certain road has been sent to a certain vehicle, the flatness information is not repeatedly sent to the vehicle, so that the waste of system resources of the road side unit system is reduced.
310. The road side unit system sends road flatness information to the suspension height adjustment system, wherein the road flatness information comprises specific positions and flatness grades.
The execution of this step is similar to the operation of step 102 in the embodiment of fig. 1, and is not repeated here.
311. And when the distance between the current position and the specific position of the road is equal to or lower than a first preset distance threshold value, adjusting the suspension of the automobile according to the suspension height corresponding to the flatness grade in the preset mapping relation.
The execution of this step is similar to the operation of step 103 in the embodiment of fig. 1, and is not described again here.
It should be noted that, when the current vehicle also stores the current road flatness information acquired by the sensor, the vehicle does not generally adjust the suspension height according to the current road flatness information, and the vehicle only adjusts the suspension height according to the road flatness information sent by the road side unit, which takes into account that when the current vehicle acquires the current road flatness information, the vehicle often runs to the road, and at this time, the suspension height is adjusted according to the current road flatness information, so that the suspension height needs to be adjusted quickly, and the current vehicle adapts to the obstacle that is met immediately, so that the vehicle jolts, and the driving experience is poor. In view of this, the current road flatness information is mainly used for sharing the road condition of the current automobile with the road side unit, so that the road side unit updates the road flatness information according to the current road flatness information, and reminds the automobile passing the road later with the road flatness information.
312. And when the distance value between the current position and the specific position of the road exceeds a first preset distance threshold value, restoring the suspension height of the automobile to the default suspension height.
The execution of this step is similar to the operation of step 104 in the embodiment of fig. 1, and is not repeated here.
