The present disclosure is related to a field of vehicle technique, and more particularly to aroad-surface detecting system and vehicle.
With the improvement of people's life, vehicles become more and more popular, and the comfort and safety in vehicle driving become more important
In the related art, the bumping degree during riding on the road of vehicle may be detected by a plurality of sensor on the road, and thereby the bumping conditions for the road on which the vehicle is riding may be determined so that it is possible for the vehicle (especially unmanned vehicle) to avoid bumpy road during the next riding.
However, in the related art, it is necessary to provide a plurality of sensors during the road detecting, and thus the detecting cost may be high.
The embodiments of the present disclosure may provide aroad-surface detecting system and vehicle, so as to reduce the detecting cost.
To achieve the above object, the embodiment of the present disclosure may provide the following technical solutions.
In one aspect, the embodiment of the present disclosure may provide a road-surface detecting system including an anti-knocking radar system and a control system, wherein the anti-knocking radar system may be configured to measure distance data for the distance from the chassis of the vehicle and the road surface and transmit the distance data to the control system, and the control system may be configured to determine that the road is a bumpy road surface if change of the distance data is more than a preset distance changing value.
In another aspect, the embodiment of the present disclosure may provide a vehicle including the road-surface detecting system described above.
The road-surface detecting system provided by the present disclosure may reduce the detecting cost by detecting the bumping conditions of the road surface on which the vehicle is currently riding by the anti-knocking radar system and control system mounted on the vehicle.
In the following, description in detail would be made on the road-surface detecting system and vehicle of the embodiments of the present disclosure in connection with the drawings.
The anti-knocking radar system 11 may be configured to measure distance data for the distance from the chassis of the vehicle and the road surface and transmit the distance data to the control system 12.
The control system 12 may be configured to determine that the road surface is a bumpy road surface if change of the distance data is more than a preset distance changing value.
More particularly, when a vehicle is riding on a normal road surface, the distance data for the distance between the chassis of the vehicle and the road surface may not fluctuate. On the other hand, when a vehicle is riding on a bumpy road surface, the distance data for the distance between the chassis of the vehicle and the road surface may fluctuate drastically and quickly. Therefore, it is possible to measure the the distance data for the distance between the chassis of the vehicle and the road surface in real-time by the anti-knocking radar system, and transmit the measured distance data to the control system 12. The control system 12 may determine the road surface is a bumpy road surface according to whether the received distance data changes and whether or not the change may be more than a preset distance changing value. The control system 12 may determine that the road surface is a bumpy road surface if change of the distance data is more than a preset distance changing value, and otherwise the control system 12 may determine that the road surface is a normal road surface. The anti-knocking radar system 11 may be standard equipment for middle or top class vehicle and therefore it may be unnecessary to mount any additional detecting devices and the detecting cost may be reduced. More particularly, the preset distance changing value may be set to any value in a range of 5-15 cm. For example, the preset distance changing value may be set to 10 cm.
The road-surface detecting system provided by the present disclosure may reduce the detecting cost by detecting the bumping conditions of the road surface on which the vehicle is currently riding by the anti-knocking radar system and control system mounted on the vehicle.
The G-sensor system 21 may be configured to detect the riding azimuth data of the vehicle and transmit the riding azimuth data to the control system 21.
Accordingly, the control system 12 may be further configured to determine that the road surface is a bumpy road surface if change of the riding azimuth data is more than a preset riding azimuth data and change of the distance data is more than a preset distance changing value.
More particularly, considering when there is a case happens, for example, tires are broken or the vehicle is passing over a deceleration zone when the vehicle is riding on a normal road, a misjudgment may occur if the determination on whether or not the road surface is a bumpy road surface only depends on the change of the distance data for the distance from the chassis of the vehicle and the road surface. A detection on the riding azimuth of the vehicle may be added considering that there may be drastically swaying and changing of riding azimuth when the vehicle is riding on a bumpy road surface, so as to exclude the misjudgment caused by change of the distance data for the distance from the chassis of the vehicle and the road surface when there is a case happens, for example, tires are broken or the vehicle is passing over a deceleration zone when the vehicle is riding on a normal road. The principle may be described as follows. The anti-knocking system 11 may measure the distance data for the distance from the chassis of the vehicle in real-time and the road surface and transmit the measured distance data to the control system 12.The G-Sensor system 12 may detect the riding azimuth data of the vehicle in real-time and transmit the riding azimuth data to the control system 12. The control system 12 may determine that the road surface is a bumpy road surface according to whether or not the received distance data changes and whether or not the change is more than a preset distance changing value and according to whether or not the received riding azimuth data changes and whether or not the change is more than a preset riding azimuth changing value. Otherwise, it can be determined that the road surface is a non-bumpy road surface, i.e., a normal road surface. The anti-knocking radar system 11 and the G-sensor system 21 may be standard equipments for middle or top class vehicle and therefore it may be unnecessary to mount any additional detecting devices and the detecting cost may be reduced. More particularly, the preset distance changing value may be set to any value in a range of 5-15 cm. For example, the preset distance changing value may be set to 10 cm. The preset riding azimuth changing value may be set to any value in a range of 10-20 degree. For example, the preset riding azimuth changing value may be set to 15 degrees.
Furthermore, the control system 12 may be further configured to transmit the information on road surface to the navigation digital map system for marking, if it is determined that the road surface is a dumpy road surface, so that the navigation digital map system may avoid the bumpy road automatically when the vehicle (especially unmanned vehicle) performs road planning for the next time.
The road-surface detecting system provided by the present disclosure may reduce the detecting cost by detecting the bumping conditions of the road surface on which the vehicle is currently riding by the anti-knocking radar system, G-sensor system, and control system mounted on the vehicle.
The ADAS 31 may be configured to detect ADAS data of the vehicle and transmit the ADAS data to the control system 12.
Correspondingly, the control system 12 may be further configured to determine whether or not the vehicle is in a lane-switching or corner overtaking state according to ADAS data, and determine that the road surface is a bumpy road surface if change of the riding azimuth data is more than a preset riding azimuth data, the vehicle is not in a lane-switching or corner overtaking state and change of the distance data is more than a preset distance changing value.
More particularly, considering the riding azimuth of the vehicle may change when the vehicle is switching lane or making corner overtaking when the vehicle is riding on a normal road, adetection on whether or not the vehicle is in a lane-switching or corner overtaking state, so as to exclude the misjudgment caused by change of the riding azimuth when the vehicle is switching lane or making corner overtaking when the vehicle is riding on a normal road.

The ADAS 31 may detect ADAS data of the vehicle in real-time and transmit the ADAS data to the control system 12. The control system 12 may determine whether or not the vehicle is in a lane-switching or corner overtaking state according to ADAS data. The control system 12 may determine whether or not the road surface is a bumpy road surface according to whether or not the received distance data changes and whether or not the change is more than a preset distance changing value and according to whether or not the received riding azimuth data changes and whether or not the change is more than a preset riding azimuth changing value when the vehicle is not in a lane-switching or corner overtaking state. The control system 12 may determine that the road surface is a bumpy road surface when the change of the received distance data is more than a preset distance changing value and the change of the received riding azimuth data is more than a preset riding azimuth changing value.
