IPGTraffic module for CarMaker
IPG Automotive has launched the latest version of the object simulation capability IPGTraffic within CarMaker. It enables the interactive generation of arbitrary traffic scenarios and is optimally suited for the MIL, SIL, and HIL testing of different advanced driver assistance systems with object detection.
IPGTraffic, which has been available since 2001, simulates freely configurable traffic situations with an arbitrary number of moving objects (e.g. traffic, pedestrians) and stationary obstacles (e.g. parking cars, crash-barriers, traffic signs and buildings) surrounding a test vehicle equipped with sensors. The module is optimally suited for the model based development of advanced driver assistance systems such as adaptive cruise control (ACC), lane change assistance, brake assistance, assisted parking, intersection assistant, congestion assistant or pre-crash systems. The control systems and the dedicated sensors can be integrated easily and quickly into the virtual test vehicle. Depending on the development stage and the test objective they are tested by model-, software- or hardware-in-the-loop in different driving situations and traffic scenarios. For an easy and comfortable set-up of test scenarios CarMaker has now been extended by a test scenario manager allowing the precise configuration of traffic situations with a time, distance or event controlled process. The type, dimensions and the starting conditions, paths, velocities and accelerations of the objects can be defined dependent or independent on each other. There is no limit to the buildup of the scenarios - either in terms of the number of objects nor to the length of the single-lane or multi-lane tracks. The traffic can be simulated on very long and real measured 3D tracks (100km and more) without problems.
A further highlight for the development of ACC etc is the TestWare for advanced driver assistance systems. It contains models, test cases, test automation procedures and post-processing routines allowing the comprehensive evaluation of driver assistance systems in the simulation with CarMaker. The extensive manoeuvre catalogue of IPG's TestWare was developed on the basis of event-tree analyses and driving tests and has been extended and optimised for simulation. It contains numerous scenarios which are necessary for the evaluation of functions, failures, fail-safe functions and the performance of the systems and goes far beyond the possibilities of the driving tests on the track. This enables the user to perform all of the important tests using a mouse click without having to worry about the programming of traffic scenarios and model details. The results are provided in an automatically generated test protocol after the simulation.
