Перезапустите ведущую симуляцию сценария с начала
Создайте ведущий сценарий, в котором транспортное средство ездит вниз по прямой, 25-метровой дороге на уровне 20 метров в секунду. Постройте сценарий.
scenario = drivingScenario('SampleTime',0.1);
roadcenters= [0 0 0; 25 0 0];
road(scenario,roadcenters)ans =
Road with properties:
Name: ""
RoadID: 1
RoadCenters: [2x3 double]
RoadWidth: 6
BankAngle: [2x1 double]
Heading: [2x1 double]
v = vehicle(scenario,'ClassID',1); waypoints = [5 0 0; 20 0 0]; speed = 20; % m/s smoothTrajectory(v,waypoints,speed) plot(scenario)
Запустите симуляцию и отобразите местоположение транспортного средства на каждом временном шаге.
while advance(scenario) fprintf('Vehicle location: %0.2f meters at t = %0.0f ms\n', ... v.Position(1), ... scenario.SimulationTime * 1000) end
Vehicle location: 7.00 meters at t = 100 ms Vehicle location: 9.00 meters at t = 200 ms Vehicle location: 11.00 meters at t = 300 ms Vehicle location: 13.00 meters at t = 400 ms Vehicle location: 15.00 meters at t = 500 ms Vehicle location: 17.00 meters at t = 600 ms Vehicle location: 19.00 meters at t = 700 ms
Перезапустите симуляцию. Увеличьте шаг расчета и повторно выполните симуляцию.
restart(scenario); scenario.SampleTime = 0.2; while advance(scenario) fprintf('Vehicle location: %0.2f meters at t = %0.0f ms\n', ... v.Position(1), ... scenario.SimulationTime * 1000) end
Vehicle location: 9.00 meters at t = 200 ms Vehicle location: 13.00 meters at t = 400 ms Vehicle location: 17.00 meters at t = 600 ms
