It winnows with a dustpan the system on road surface, guarantees vehicle in the case where driver neglects or has little time switching, remain to even if automatically switching to track
Mode, it is ensured that driving safety, vehicle performance and the riding comfort of bumpy road.
Bumpy road identification method in the prior art has following several:
One is using vehicle self-carrying anti-collision radar system and gravity sensor, measure chassis at a distance from road surface and
The traveling azimuth of vehicle, when the variation of traveling bearing data is more than preset travel azimuthal variation value and chassis and road surface
Distance change is more than pre-determined distance changing value, it is determined that the road surface is bumpy road.And judged by ADAS and GPS system
The steering state of vehicle is mistakenly identified as bumpy road to avoid by azimuthal variation caused by normal turn state；
One is by installing a kind of detection device, to measure from vehicle body point to the distance and vapour to Chinese herbaceous peony point
Offset data of the vehicle vehicle body relative to reference direction, when institute's detection data is more than pre-determined distance changing value, it is determined that the road surface
For bumpy road.And the steering state of vehicle is judged by navigation system, to avoid by orientation caused by normal turn state
Angle variation is mistakenly identified as bumpy road；
One is by installing multiple laser sensors and dynamic inclination sensor in roof, vehicle travel process is calculated
The combination angle of two sensors, the variation by combining angle, which estimates, is currently located road bump degree, adjusts vehicle accordingly
Gear, improve vehicles dynamic performance；
One is the pavement identification methods based on Car window electric machine revolving speed, by monitoring vehicle window motor speed value, and to the letter
It number carries out handling and comparing with threshold value, to judge whether in bumpy road.

Misrecognition, because many operations on normal road surface can also be related to travelling azimuthal variation, although introducing ADAS and GPS
Error correction is carried out, but the two input precisions are not so high, to introduce new error, reduce accuracy of identification；
Second and the first thinking like, the disadvantage is that using body of a motor car relative to reference direction offset data as running
The judgement input on road surface of winnowing with a dustpan can be easy to misidentify, because many operate on normal road surface can also be related to travelling azimuthal change
Change, although introducing navigation to judge whether vehicle has the steering to be intended to and carry out error correction, navigation accuracy so high,
To introduce new error, accuracy of identification is reduced.In addition, the invention introduces new detection device, increase cost, and once because
Cause overall height to change for reasons such as tire pressures, needs to re-scale.
The third patent core be exactly the multiple laser sensors and dynamic inclination sensor for being mounted on roof quantity,
Position, angle, variable is more, and calibration is cumbersome, and difficulty is big when being generalized to other vehicles, introduces so multisensor, at high cost, and
