智能驾驶相关 轨迹跟踪 模型预测
Abstract—Path tracking issues of autonomous ground vehicles
(AGVs) have attracted more attention in recent years with the
intelligent and electrified development of vehicles. In order to
make AGVs path tracking problem more flexible, regional path
tracking problem is discussed in this manuscript based on model
predictive control (MPC) method, where the front wheel steering
angle is regarded as the control variable. The feasible region
for AGVs running is determined first according to the detected
road boundaries. In the following, AGVs running in this region
is considered using kinematic model. Then, in order to make
the actual trajectory of AGVs keep in the region and satisfy the
safety requirements, MPC method is employed to design path
tracking controller considering the vehicle dynamics, the actuator
and state constraints. In order to verify the effectiveness of the
proposed algorithm, simulations under various test conditions
are carried out using a high fidelity vehicle simulator veDYNA,
where the Hongqi vehicle HQ430 parameters are matched. The
results obtained from the simulation illustrate that the proposed
algorithm obtains good performance in dealing with the regional
path tracking problem.
