Function needs

To implement X-by-wire and a number of driver assistance functions, sensors are required to monitor the clutch, brake and accelerator pedal position and send the information to electronic control systems. This can be done by various types of position sensors or switches located on or near the pedals or their operating mechanisms.

Sensors needs

The sensors that provide this information must offer:

• High accuracy
• Small size
• Fast response
• Easy integration
• High reliability
• Diagnostic capabilities

Depending on where they are installed, they must also withstand severe environmental conditions:

• High temperatures
• Rapid temperature fluctuations
• Electromagnetic disturbances
• Vibrations
• Corrosive liquids

• Analysis of customer needs to select the most suitable sensor type from our proven core technologies (LVDT, Hall, Eddy-Current, GMR, AMR, VR, etc.)
• Determination of degree of integration (single sensor, sensor cluster or mechatronic module)
• Circuit design and ASIC development if required
• Selection of electronic components and assembly technology (e.g. surface mounted devices, discrete components)
• Package design, including the selection of materials (PA, PPS, PBT, etc.), assembly process (laser, thermal or vibration welding), potting, overmolding and encapsulation techniques, sizing, etc.
• Selection of interconnections (leadframe, flex foil, cable harness, etc.)
• Magnetic circuit design (magnet materials, pole piece dimensions, etc.)
• FMEA, reliability studies, computer simulations, prototyping, initial samples, etc.
