Auf der 2013 Zulieferer Innovativ EFI Automotive präsentiert die 2. Generation EMPOS.

EMPOS sensors for rotor position measurement

Rotor position is a key input parameter for the control of permanent magnet synchronous motors (PMSMs). To deliver this information and meet the constraints of electric and hybrid vehicles, EFI Automotive has developed the EMPOS sensor designed with planar primary and secondary windings integrated on the PCB in a water-and oil-tight package.

Insensitive to severe magnetic disturbances, EMPOS Electric Motor Position Sensors use eddy-current technology to quickly and accurately measure the absolute angular position of the rotor, even at very high speeds.

With integrated electronic processing, this innovative sensor delivers a simple, clean and accurate digital signal. It offers excellent resistance to the severe electromagnetic environment of electric motors at a competitive cost. It is extremely compact and designed for simple connection.

With EMPOS, EFI Automotive introduces another technological breakthrough to improve the control of electric motors.

Thin (< 10mm) and lightweight (< 100g), accurate (± 1°) and Plug & Play digital connection.

Higher efficiency, improved comfort, smoother acceleration, better mileage and longer range.

Innovation 1

Developing Embedded smart modules for tomorrow's vehicles

Technically speaking, building the vehicle of tomorrow involves seven major challenges:

  • cut fuel consumption,
  • reduce emissions,
  • improve energy management,
  • enhance driver comfort and assistance,
  • propose systems for robust environments,
  • anticipate on future standards (Euro 7, etc.)
  • grow the hybrid and electric vehicle market.

EFI Automotive is already working to meet these challenges, developing embedded smart modules to help car manufacturers keep pace with driver expectations.

Shifting its outlook from components to systems and instrumentation, EFI Automotive has structured its offering around smart sensing and actuation solutions.

Innovation 2

  • Drivetrain
    Gaining a competitive edge with stop-start as standard equipment
    Stop-start systems automatically switch the engine off when vehicles stop temporarily, significantly reducing fuel consumption. Applying its extensive system know-how, EFI Automotive has developed a range of dedicated product s for these increasingly popular stop-start systems. They carry a high added value, allowing manufacturers to out-distance the competition by offering stop-start as standard equipment. Such solutions are also decisive in efforts to comply with CO2 emission standards.

Innovation 3

Powertrain actuation

innovative solutions for intelligent thermal management

More than 90% of pollution from vehicles is emitted during the first 50 seconds after starting a cold engine. For this reason, manufacturers are looking for ways to improve the responsiveness and accuracy of temperature control. The most effective solution to achieve this objective is to replace mechanical thermostats by intelligent systems.

Intelligent thermal management makes it possible to reach the optimum engine temperature faster and to maintain it while the engine is running. The result is lower fuel consumption, lower emissions and greater passenger comfort.

  • Water control loop
    Actuator module with integrated sensor

    The use of mechatronic modules integrating electronically controlled sensors and actuators is a new and innovative solution for intelligent thermal management. Developed by EFI Automotive within a partnership, this module offers more accurate and therefore more effective control, all in a smaller package.
  • Air management
    Integrated solutions for more efficient air control loops

    New engine types use advanced air control loops to help reduce the amount of nitrogen oxides emitted by internal combustion. Examples include low and high pressure exhaust gas recirculation systems (EGR) and swirl and tumble air intake systems. These functions help manufacturers comply with Euro 5 and Euro 6 norms and adapt engines to the increasing use of biofuels and new combustion processes.
  • Fuel injection

    An economical and silent solution for high-precision, high-pressure injection, ideal for upcoming "clean" diesel engines.

    high-precision injection for clean combustion

    For diesel engines, optimum fuel injection is a decisive factor in efforts to boost efficiency and cut fuel consumption and emissions. The injection actuator is at the heart of the system that controls the quantity of fuel injected in the engine's cylinders.
