IPG Automotive releases version 9.0 of the CarMaker product family
IPG Automotive’s release 9.0 of the CarMaker product family includes new applications for virtual vehicle development, including cooperative driving with SimNet, advanced and new sensor models, and the parallelization of multiple GPUs. In response to the societal megatrends of digitization and autonomous driving leading to higher validation efforts in vehicle development, the company consolidated its products particularly in the fields of performance and flexibility of scenarios.
New, improved, and validated sensor models
With the release 9.0, the calculations of Radar RSI switch to physically based field calculations. A wide range of effects are thereby considered before the raw data is then processed in a signal processing model. Radar RSI was validated in an extensive measurement campaign in cooperation with Magna Electronics.
To support the functionality tests more extensively, the Camera HiFi Sensor is added to the list of High Fidelity (HiFi) Sensors. It generates camera-specific object lists of recognized traffic objects, traffic signs, and traffic lights. Various effects need to be taken into consideration, for example occlusion or influence of rain or fog.
Further, the new release introduces a new Ideal Sensor. The Object by Lane Sensor identifies traffic objects on selected, adjacent traffic lanes and provides information about the lanes, as well as about the traffic objects using them. The company says this is why the sensor is perfectly suitable for trajectory planning.
Flexible and detailed scenario generation
In order to provide quick and easy access to realistic road networks in CarMaker, map data including road characteristics as lanes, lane markings, and speed limits from HERE HD Live Maps is available for import. The user decides whether to load a selected section of a road network or the required roads along a definable route.
The new release also enables exports of road networks created with the Scenario Editor not only in the ROAD5 format but also in the OpenDRIVE open file format. In this way, the user can exchange with other platforms and once produced, road networks can be reused more often.
Other new features in the Scenario Editor include new possibilities for an easy definition of traffic signs and traffic lights, as well as the corresponding functional markings. By allocating different speed limits to different traffic lanes on the road and through traffic lights located on the opposite sides of an intersection, the user profits from maximum flexibility when configurating scenarios.
In addition to the so far generic Traffic Model, a Human Driver Model is available. According to the company, the behavior is thereby not only enhanced during lane switching, but also models human traits as reaction time or imprecise estimations of distance and speed. Therefore, the behavior of road users appears more realistic and human-like.
The use of cooperative driving as basis for applications such as V2X communication or platooning has already been possible with the simulation solutions of the CarMaker product family. With the release 9.0, cooperative driving with SimNet now becomes a regular feature. It allows for simulation in one common scenario of up to 10 ego vehicles on a single computer or up to three ego vehicles in a network of CarMaker, TruckMaker, or MotorcycleMaker.
