Abstract  To solve the parking trajectory error caused by time-delay in voice-assisted semi-automatic parking system, a kinematics model of auxiliary parking was established. And also parking planning methods and control strategies based on horizontal parking spaces were proposed. Using the 3-order polynomial fitting to deduce the piecewise approximation function of parking trajectory which took the lateral distance D between the vehicle and the target parking space as the variable, the impact of time-delay on actual trajectory in voice-assisted semi-automatic parking system was simulated and analyzed. Parking trajectories were independent variables, and the horizontal and vertical deviation of parking trajectory were evaluation indices. Relations between each trajectory deviation and the final parking position deviation were derived. Through simulation, tolerance analysis for parking path deviation was conducted. The parking dynamical adjustment strategy was proposed based on the method of table look-up, and also it was achieved through software programming. Finally, group tests from 4 drivers verified the validity of parking dynamical adjustment strategy.

语音泊车时滞影响及轨迹动态调整策略研究

针对语音辅助半自动泊车系统中的时滞导致泊车轨迹误差较大的问题，建立辅助泊车运动学模型，提出水平侧方车位泊车轨迹的规划方法和控制策略.采用3次多项式拟合推导出以车辆与目标车位横向间距D为变量的泊车轨迹分段逼近函数，仿真分析了语音辅助半自动泊车系统中时滞对实际泊车轨迹的影响.分别以泊车轨迹每段弧长为自变量，以泊车横、纵向偏差为评价指标，推导了各段轨迹弧长偏差与最终泊车位置偏差的关系，通过仿真对泊车路径偏差进行了容差分析，提出了基于查表法的泊车动态调整控制策略，并通过软件编程实现.最后通过4名驾驶员分组试验，验证了泊车动态调整策略的有效性.
