如何在相扑文件中设置车辆以恒定速度行驶？

Question

如何设置车辆以恒定速度行驶？我发现车辆的速度首先增加，然后在相扑中以 14.5 到 14.7 m/s 的速度行驶。但我希望汽车在相扑中以恒定速度行驶。我该怎么办？

Answer 1

您需要通过将 sigma 设置为 0 来禁用随机磨合，并以最大速度开始。为此，您需要定义车辆类型：

<routes>
    <vType sigma="0" id="t1"/>
    <route edges="gneE0 gneE1" color="yellow" id="route_0"/>
    <vehicle id="vehicle_0" depart="0.00" color="red" route="route_0" departSpeed="max" type="t1"/>
</routes>
