TOYO Corporation Acquires Leading European Dynamometer Manufacturer Rototest

Advances TOYO’s strategy to expand its global business presence in the rapid-evolving automotive test space

Fremont, Calif., November 30, 2023  – TOYO Corporation (TOYO), a leading provider of advanced measurement solutions and Rototest® International AB (Rototest), a global innovator in the development of hub-coupled powertrain dynamometers, today announced that TOYO has acquired Rototest on November 30, 2023, Japan time. Henceforth, Rototest, headquartered in Rönninge, Sweden, will operate as a subsidiary of TOYO.

An automotive powertrain dynamometer is a testing apparatus used to measure and record mechanical parameters, such as power, torque, and speed, at an automobile’s drive wheels. According to the analyst firm IndustryARC, the global market size for automotive dynamometers was projected to be USD $928.1 million in 2021 and is expected to reach USD $1161.5 million by 2027. Key factors driving the market demand include the rapid and transformative innovations in the domains of electric vehicles (EV), autonomous driving (AD), advanced driver assistance systems (ADAS), and connected cars.

ADAS, AD, and other newer automotive innovations are technological marvels, but they pose significant challenges in terms of development and testing. Modern approaches, such as model-based development (MBD), have been adopted to address many of these challenges. MBD involves designing and developing components and entire vehicles through computer-based simulations. The industry also employs a process known as Hardware-in-the-Loop (HIL) testing, where thorough simulations involving actual hardware components are conducted to further support testing demands.

In 2016, TOYO forged a partnership with Rototest to introduce their hub-coupled dynamometers to the Japanese automotive market. The solution gained widespread acceptance due to its short setup time, user-friendly design, and portability. Since then, TOYO has expanded its dynamometer offerings by integrating them with radar and camera simulators, among other components, resulting in the creation of the Driving & Motion Test System (DMTS). This integrated system plays a crucial role in accelerating the automotive development cycle, allowing for the evaluation of diverse functions, and facilitating simulated indoor testing that accurately mirrors real-world conditions.

In December 2023, TOYO is set to deliver a DMTS to the Japan Automobile Research Institute to support their HIL testing needs. On the other side of the world, TOYOTech, TOYO’s US subsidiary, has been awarded an order for two Rototest dynamometer systems from a major automaker to accelerate their EV initiatives.

TOYO has undertaken the development of a Vehicle-in-the-Loop (VIL) solution anchored by Rototest dynamometers. VIL testing is an approach that bridges the gap between software and hardware simulations and full road testing. It involves conducting comprehensive and complex simulations using real vehicles for testing and complements existing HILS tests. This represents the final testing step that can take place in a lab setting.

Christian Engström, Rototest’s CEO, expressed, “TOYO acquiring Rototest marks a significant milestone for the company. With TOYO, Rototest is poised to enhance its ability to provide innovative automotive test solutions to an even broader array of the world’s leading manufacturers.”

Wireless Communication Performance Measurements Commences in China

Testing Operations for Connected Vehicles Begin at CICV, a Chinese National Research Institute  

Fremont, Calif., September 15, 2023  – TOYO Corporation, a leading provider of advanced measurement solutions headquartered in Tokyo, today announced that its Chinese subsidiary, TOYO Corporation China (Location: Shanghai, China), has delivered a wireless communication performance measurement system for connected vehicles for the test service launched in July 2023 by China Intelligent and Connected Vehicles (Beijing) Research Institute Co., Ltd. (headquartered in Beijing, China; hereinafter referred to as “CICV”), a national research institute in China.

There is growing importance in OTA (Over-the-Air) measurement of in-vehicle wireless communication performance for the development of ICV (Intelligent and Connected Vehicle) technology that will realize safe and efficient autonomous driving through advanced communication technology and artificial intelligence. As a national research institute leading the ICV industry in China and playing a central role in R&D for ICV technology, CICV aims to become a think tank and a center for R&D of common technologies and test facilities. ICV utilizes a variety of wireless communication technologies, including V2X (Vehicle to X), mobile communications, and GNSS, and faces numerous challenges due to their communication functions and complex systems. To address these challenges, CICV established a “Vehicular Wireless Communication Lab” and launched its test service for customers both in and outside of China in July 2023.

The system delivered by TOYO to CICV has been developed by applying the OTA test method created originally for mobile terminals and antennas by General Test Systems Inc. (hereinafter “GTS”). As an industry-leading expert in the field of mobile terminals, antennas, and OTA testing, GTS has utilized the patented Radiated Two-Stage (RTS) method, approved by 3GPP (Third Generation Partnership Project, established in December 1998 by the standardization organizations of various countries to promote 3rd generation cell phone technology), as a test method for LTE mobile terminals and base stations, for in-vehicle wireless communication performance measurement.

Compared to conventional methods, this system uses more theory-based calculations to derive measurement results and was selected because it is a cost-effective solution with fewer sources of measurement error, enabling simpler measurements. The system covers a wide range of testing, from testing in-vehicle antennas alone to communication testing for evaluating the quality of V2X communication.

Taking advantage of this opportunity, TOYO will continue to contribute to the development of safer mobility and next-generation transportation systems by offering a variety of measurement solutions required for the development of autonomous driving (AD) and advanced driver assistance systems (ADAS), including the Wireless Communication Performance Evaluation System, to markets both in Japan and overseas.

Key features include:

• Uses GTS’s patented RTS method approved by 3GPP
• Capable of 3D MIMO (Multiple Input Multiple Output) testing, even on large test objects such as automobiles
• Supports various test items, including antenna radiation performance, receiver sensitivity, electromagnetic interference reception, multi-antenna performance evaluation, and vehicle communication performance evaluation under real-world conditions

Tests performed by CICV’s Vehicular Wireless Communications Lab:

• Passive and active tests of antennas and wireless systems at the full-vehicle level
• Vehicular GNSS performance tests
• Vehicular MIMO communication system tests
• Vehicular multi-wireless system compatibility tests
• Vehicular C-V2X access layer RF/protocol compliance certification
• Vehicular C-V2X network layer/message layer protocol conformance certification
• Vehicular C-V2X functional verification
