2 02 Business Overview Accreditations In today s automobile industry, systems controlled by sensors have become an integral part of safe and secured life, and this has made most electro-mechanical devices more refined and more efficient with their applications. We have set up a separate sensor team in 1995 and started sensor business with electric pressure sensor. We have also started to supply sensors for automotive industry since QS 9000, ISO 14001, ISO/TS16949, OHSAS18001, CMMI L2 & L3, ASPICE L2 Currently we supply sensors in various applications For power steering system, we supply steering angle sensor, torque sensor and torque angle combined sensor. For transmission, we supply position sensor and Yaw &G sensor for brake and ESC system. For emerging EV/HEV application, we supply current transducer for battery and VR type resolver for EV traction motor and hybrid system. R&D Capability Although the development and deployment of a number of sensing technologies are emerging in automotive industry, there are challenges regarding robustness, reliability, quality and cost. We have our own capability to design, develop and produce automotive sensor satisfying these challenges. Magnet Field Sensing Technology We have rich experience and know how of analysis of magnetic field and its sensing mechanism. Various projects enable us to build up high accurate analyzing technology of magnetic field and to develop sensing algorithm. Based on this technology, we have expanded our sensor application. For steering angle sensor, we developed our own algorithm and registered design resulting the flexibility in design. For torque sensor, we have our own patent for magnet inducing way and the sensor structure. As a result, we can give additional benefits to customer. DAESUNG Sensing Technology Customers 11

6 06 Sensor Products for Green Car Current Transducer We supply open loop Current Transducer to measure current of HEV/EV using programmable hall IC. It is designed to work with a single +5V power supply to cover the whole primary current ranging from negative to positive current and optimized to minimize bus bar effect. We supply Current Transducer in different types for different applications for Inverter and HDC and for battery pack and BDU (Battery Disconnect Unit). Resolver Current Transducer Resolver Resolver is designed to realize the highly accurate absolute angle measurement and the extremely reliable usability in harsh environmental conditions. We developed VR type resolver that produces two analog output signals with two phases proportional to sine and cosine of the angle of rotor by detecting a change of air gap (Permeance) between the rotor and the stator. We apply this resolver to measure absolute position and velocity and apply this to traction motor and transmission of HEV/EV.
