Infineon in automobiles Infineon supplies sensors, microcontrollers and power semiconductors for the automobile industry. These products help to make vehicles safer and more driver-friendly and to boost fuel efficiency while reducing carbon emissions. On average, every new car manufactured today contains roughly two dozen Infineon chips, including around four sensors (for antilock braking systems and side-impact airbags, for example). One in two automobiles in Europe and one in three worldwide is equipped with an Infineon microcontroller for managing diesel and gasoline engines. Among other things, these chips are responsible for ensuring an optimum air/fuel mix and optimum injection and ignition timing for each cylinder in the engine, making motoring as fuel efficient as possible. Infineon chip solutions for market-viable, affordable electric mobility Infineon products are also used in hybrid and electric vehicles. In electric vehicles they help to radically reduce the cost of the powertrain and electronics, to increase mileage and to improve battery efficiency. Today, Infineon already supplies products that boost battery life and capacity by at least 10 percent.
