Background technology
As automotive industry develops, vehicle appearance increasingly fashion, equipment more and more convenient, performance is become better and better, simultaneously
Requirement more and more higher of the customer to modern vehicle, in addition to security and outward appearance, the driving performance of vehicle is increasingly turned round and look at
The concern of visitor, driving running deviation performance is exactly wherein important one of road holding.Not only having in China's vehicle national standard can not
Outside the requirement for occurring sideslip, and requirement of the customer to driving running deviation is more and more stricter, in recent years, and vehicle is travelled on vehicle market
The Customer Complaint of sideslip is always one of subject matter.Therefore vehicular manufacturer and retailer to can effective objective measurement go out
The equipment of automobile driving running deviation amount has very big demand.Running out the way is that its straight line travels the process on flat road
In, the phenomenon being voluntarily inclined to side direction.Sideslip distance is that the distance that vehicle is inclined to side direction is referred to as sideslip distance.
At present, the main limited location block method of the method for the objective detection of driving running deviation, laser method, GPS location detection method, these sides
Method can not either measure specific running deviation value or expensive or can only be used in fixed-site.
These methods have certain limitation using equipment, specific as follows：
1st, limited block method
The limited block of fixed position relation is used in road survey final position, qualitatively judges whether vehicle has sideslip
Problem.
Shortcoming：
(1) it can only qualitatively judge, it is impossible to which objective measurement goes out specific driving running deviation amount；
(2) to prevent from shifting by mistake, limited block need to be fixed on road, and dismounting is difficult.
2nd, GPS location detection method
Using GPS location instrumentation, the sampling of whole vehicle movement process is divided into n unit point, passes through collecting cart
The distance between driving trace monitoring vehicle position and center line obtain driving running deviation amount.
Shortcoming：
(1) the high u of GPS location special equipment price is expensive, reaches the GPS device of measurement accuracy requirement and at least needs 200,000
(2) the initial alignment time is longer before measurement every time；
(3) equipment operation is relative complex, and the 0vehicle marketing business popularization for being not easy to technology weakness relatively is used.
3rd, laser detection method
Driven using laser range sensor by electric rotating platform, the rotation sweep vehicle in the range of certain angle, quilt
Measuring car is upper equipped with two reflectors, and laser range sensor measures the centre of gyration to the distance of reflector in real time, according to triangle
Rule calculates the running deviation value of vehicle.
Shortcoming：
(1) the expensive laser equipment for reaching measurement accuracy requirement of GPS location special equipment at least needs 180,000；
(2) equipment needs to be fixed on for a long time on a certain road, it is impossible to arbitrarily dismounting, therefore there is limitation in measurement place；
(3) influenceed greatly by ambient light change, precision may be influenceed.
(4) brake and sideslip instrument is all closely similar, be all very expensive.
