The automotive electronics industry is a central pillar of EPCOS’ business. Nine out of ten innovations in an automobile are driven by electronics. For more than 40 years, the electronics content in cars has been rising. The first electronic fuel injection system was launched in the 60s. This was followed by antilock brake systems (ABS) in the 70s, mass-produced airbags in the 80s and electronic stability control in the 90s. Automobiles of the 21st century can receive TV programs and access the Internet. They may also be equipped with tire pressure monitoring systems, for example, that use surface acoustic wave (SAW) resonators from EPCOS to transmit tire data. Today's cars aim to provide greater energy efficiency, safety, and convenience. But modern engine management, heating and air conditioning, keyless entry and alarm systems, and high-intensity discharge headlamps would all be inconceivable without electronic components. Steering and braking systems are increasingly being actuated, or at least assisted, electronically. But none of these systems can work properly unless the various electronic control units are fully protected against both mutual and external electromagnetic interference. That's why numerous EMC components from EPCOS are used in each vehicle to ensure electromagnetic compatibility. |

| We are helping to boost the energy efficiency of automobiles with our piezo actuators, for example, which are the heart of modern fuel injection systems. Car manufacturers use piezo fuel injection systems for both diesel and gasoline engines in order to control the fuel injection process more precisely, and thus the amount of fuel injected more finely. This permits more efficient combustion with lower harmful emissions. Electronic components are establishing themselves in other applications in vehicle drive trains. In engine management, for example, EPCOS’ sensors are used to measure the temperature of operating fluids and to measure the vapor pressure in exhaust recirculation systems. |

| We offer SAW resonators, for example, for high-precision sensors that monitor tire pressure. SAW resonators from EPCOS are key components for the wireless transmission of tire pressure and temperature data. |

| We also have a broad range of products for the growing number of convenience systems in cars. SAW resonators in hermetically sealed SMD ceramic packages, for example, stabilize frequencies and ensure reliable, interference-free transmission of radio-frequency signals for keyless entry systems and electronic immobilizers. Miniaturized data line chokes from EPCOS ensure reliable data communication between the electronic control units in automobiles at rates as fast as one million bits per second. Our portfolio of these products is the broadest in the world. Now, new more powerful in-car information highways with data rates of up to 10 million bits per second are placing even tougher demands on the suppression of electromagnetic interference (EMI). With its FlexRay chokes EPCOS has risen to this new challenge. |
