ADAS and AV: Moving Objects and Sensors
CarSim, TruckSim, and BikeSim support Moving Objects and Sensors that are essential for simulations involving advanced driver assistance systems (ADAS) and autonomous vehicles (AVs).
Key Features
Support for up to 200 independent objects representing traffic, pedestrians, animals, fixed objects, and more.
Up to 99 ADAS sensors with customizable location, range, and detection parameters.
Control object motion using built-in options, VS Commands, or external models like Simulink.
Objects can have rectangular, circular, linear, or polygonal shapes for realistic detection.
Objects can be linked to 3D models with embedded animations like walking pedestrians or pedaling cyclists.
Sensing capabilities that account for occlusion (blocking) between objects.
Traffic and Target Objects
A VS Moving Object is something with a location and orientation that might be of interest when simulating a vehicle in a VehicleSim product. As a minimum, the object is represented by a set of variables that define a location and orientation for animation or communication with other software. When combined with ranging sensors, the object becomes a target that can be detected.
Advanced users can control the motions using built-in options, with VS Commands, or with external models (e.g., Simulink). They can also be attached to vehicle sprung masses to make the vehicle detectible.
If using custom controls, each object can be located in the XY plane using either X and Y global coordinates, or using a station coordinate S along with a specified Reference Path ID. Vertical information can be set directly, or based on S and L coordinate for a specified VS Road.
ADAS Sensors
BikeSim, CarSim, and TruckSim support up to 99 ADAS sensors that detect the moving objects. An extended license is needed in order to use ADAS sensors. However, moving objects are available with any license.
Each sensor has a location fixed in a part of the simulated vehicle, with a designated aiming direction and sensitivity to radiation pattern and range. Alternatively, sensors may be located in moving objects.
The main outputs of interest are variables that link a sensor to a detected object. Each possible combination of sensor and target object has an associated set of 24 detection variables that can be used in user-defined models to simulate advanced intervention controls. The detection variables include bearing angles, distances, coordinates and speed components in the sensor coordinate system, user-defined variables, etc.
