英文摘要: |
On the basis of pure pursuit algorithm analysis published or used in recently years, a model of two-step pure
pursuit course correction algorithm was designed, vehicle heading angle was corrected, thereby reducing the lateral error
of the vehicle body. The simulation results under Matlab show that the algorithm is more accurate than the pure pursuit
algorithm, and the maximum error and standard deviation are all reduced. In the four-wheel electric car. a set of
hydraulic system and a set of satellite receiving systems were built. and the algorithm field test was carried out to verify
the feasibility and effectiveness. |
