New Vehicle Techs at 2017 AutoTronics Taipei

“Electrification” and “intelligence” are the latest buzzwords in automobile technology. As forecast by ITRI IEK, the production value of the global automotive electronics and Internet of Vehicles (IoV) industries will reach US$451.1 billion by 2023, 1.67 times higher than the US$270.3 billion in 2015. The highest growth will be in sectors related to active safety and energy-efficient systems, with an expected annual growth rate of 25% or higher. To address the market demand, ITRI showcased its latest intelligent and energy-efficient vehicle technologies at the 2017 AutoTronics Taipei.

Belt Starter Generator (BSG)

BSG is the first of its kind to be developed in Taiwan. In contrast to other hybrid and electric systems, BSG is more cost-effective and adaptive. It can replace the traditional alternator as it reduces energy consumption by 10% to 15%, while featuring stop-start, engine boost, electricity generation, and regenerative braking. The application of the hairpin winding effectively improves the copper space factor and reduces inefficient end wires. The intelligent power module (IPM) and film capacitor in its controller can save space and thereby boost power density, adding to its competitive edge.

Synchronous Rectifier Generator

ITRI replaced the high-power-consuming rectifier diode with a low-internal-resistance power MOSFET to produce a highly reliable, active synchronous rectification control technology. Based on the non-transient nature of the generator revolution, ITRI developed frequency forecasting and tracking techniques. Moreover, it integrated the voltage and current detection and protection design. With the multi-layered protection mechanism that involves voltage, current, and revolution, the reliability of the synchronous rectifier generator and the safety of the automatic switch are both improved.

Intelligent SiC Power Module in Motor Driver

The power module is the core component of the motor driver and is also the major culprit related to system failure. ITRI’s intelligent power module features system integration, heat-resistant assembly and junction, module risk pre-diagnosis, and parameter real-time monitoring. It can significantly reduce industrial and vehicle energy use, shrink system size, and improve equipment safety and reliability. Meanwhile, the application of SiC MOSFET can bring power and electronics industries to new heights by reducing carbon emissions and enhancing overall energy conversion efficiency.

Driving Perception Platform

In response to the growing demand for vehicle intelligence and safety, ITRI has brought together disciplines which include information, communications, electronics, and mechanical engineering to develop image deep-learning and perception system technology, in seeking to achieve a broader technology integration. At present, ITRI is cooperating with a local logistics company on unmanned vehicle applications. A customized driving perception platform has been developed for driverless shuttle tests within a closed area. The perception platform that includes AI image recognition and control strategies can lead suppliers to develop product parts and systems for autonomous vehicles.

Long-Distance Floating Multi-Screen HUD

ITRI employs a MEMS scanner to project images into the driver’s field of vision at a two-meter distance behind the windshield and its Butterfly Beam-Splitter technology to divide a 26” wide screen into three separate parts. This allows the driver to read navigation information, images of the sides of the car, and traffic information without having to look away from the road, thereby ensuring safe driving. This technology won a 2016 R&D 100 Award. This year, with the introduction of a laser projector, the device is not only more reliable and durable, but also 42% more compact, which meets the needs of the automobile OE and AM markets.
