OTSL Inc., short-distance wireless system and embedded system developer and distributor, has announced that it has established partnerships with three companies providing advanced technologies related to electronic systems and autonomous driving. OTSL has joined with Germany’s COSEDA Technologies GmbH, US-based VectorZero and AILiveSim of Finland to strengthen the ecosystem for the former’s 3D real-time sensor simulator framework COSMOsim, which is aimed at autonomous driving.
COSMOsim is claimed to be the only platform that can simultaneously run five types of simulators in real time on a single screen. The five simulators can run validation corresponding to millimetre wave radar, LIDAR, cameras, infrared light and ultrasonic wave sensors. OTSL said that as autonomous driving continues to move toward practical use around the world, there is increased demand for powerful simulation technologies that can virtually recreate diverse driving conditions to enable safe and accurate verifications.
The company’s partnership with COSEDA Technologies enables the development of autonomous driving systems that link the latter’s electronic system design tool COSIDE with COSMOsim, noted OTSL. An autonomous driving system simulation environment can be built on COSIDE, which uses IEEE Std 1666.1-2016 SystemC AMS language, where all simulations are based on software, ranging from semiconductors to vehicle systems. There is no need to prepare automobile hardware such as sensors and ECUs, as everything can be simulated through software, which significantly reduces development time and costs, it observed. COSEDA’s system-level simulation technology enables the verification of sensors and ECUs in the initial stages of design, functional safety factors and compliance with standards in near future.
Meanwhile, OTSL said COSMOsim is compliant with ASAM OpenDRIVE, a file format for describing the form of road networks necessary for driving simulations. Through the partnership with VectorZero, COSMOsim can now read and write ASAM OpenDRIVE files using RoadRunner, VectorZero’s road modelling and traffic simulation tool. This enables COSMOsim to recreate more realistic road conditions, such as intersections, bridges, and road signs. Complying with international road network standards means that OTSL can offer a highly-accurate simulation environment to companies in the global autonomous driving market, the company noted.
Finally, partnering with AILiveSim enables COSMOsim to link with the next-generation AILiveSim autonomous driving simulation platform, which employs deep learning technology. With this partnership, COSMOsim’s diverse sensor simulation techniques can be applied to maritime traffic as well, enabling OTSL to expand the business field of its autonomous driving simulator products. AILiveSim and COSMOsim use the same game engine - Unreal Engine 4, and are therefore highly compatible, OTSL pointed. It also makes it easy to effectively use AILiveSim’s main characteristics of Artificial Intelligence and Deep Learning in COSMOsim and achieve a level of performance in autonomous driving simulations not yet seen.
Shoji Hatano, CEO, OTSL, said achieving completely autonomous driving requires moving beyond vehicle-mounted sensors and automotive systems such as ECUs and in-vehicle networks. It requires the creation of an environment in which the countless factors involved in automotive societies - roads, surrounding environment, human engineering - can be simulated with a high level of accuracy, he added. Hatano noted that by partnering with global companies that offer the most cutting-edge technologies to construct the ecosystem, OTSL is aiming to create an advanced autonomous driving simulation environment at the earliest.
