Realizing that innovations in electronics can complement production innovations in gaining a competitive advantage, semiconductors are becoming increasingly important in the automotive value chain. Sensing is a major function of the electronics system, with position sensors as the biggest market segment in regards to automotive sensor demand. Magnetic position sensors in vehicles are increasingly installed for applications such as throttle valve position, suspension control, power assisted steering, electronic gas pedals, electronic brake pedals and adaptive headlight systems. In addition to previously mechanically-driven applications such as power steering, transmission actuation and engine cooling systems are also increasingly being electrically-powered, driving the demand for brushless DC motors and therefore stimulating the demand for motor position and control sensors in the automotive sector.

Electromagnetic Interference (EMI) has become a growing concern due to the increased electrification of automobiles, and particularly so with electric cars where large high current carrying wires run between the front and back of the vehicle. Magnetic position sensors with integrated stray field cancelation features provide high accuracy measurements even in the noisiest of EMI environments, commonly found in automotive applications.

For the first time, designers of high-speed electrical motors can use robust, compact magnetic position sensors, without the need to implement complex angle error compensation schemes in an external microcontroller or DSP to account for motor-shaft rotational rates. New magnetic position sensors with integrated Dynamic Angle Error Compensation (DAEC™) functionality deliver state-of the-art accuracy and increased signal performance by accounting for motor-shaft RPM speeds. In high-speed brushless DC (BLDC) motors the sensor’s high accuracy enables better execution of the commutation scheme, resulting in higher torque and efficiency, lower torque ripple and smoother operation.
The problem with the existing magnetic position sensors on the market is a delay which comes by nature with the signal processing. This led to wrong angle position outputs, especially at high rotation speeds. The value of the so called dynamic angle error depends on rotation speed. Additional hardware chips can calculate this error and do a software correction on the output angle. Therefore a huge software development is needed. But still this result is not as good as the DAEC™ from ams. The DAEC™ Dynamic Angle Error Compensation is the unique feature of the new generation of ams’ position sensors. It is a single chip solution which reduces the Dynamic Angle Error almost to zero. Of course it delivers all the advantages of contactless angle measurement and there is a much better accuracy over speed. By the way it is easy to use, simple to program and reduce development costs as well as time to market.

Magnetic position sensors with new digital output interfaces deliver flexible and reliable communication standards for improved automobile safety and performance. For example, the SENT (Single Edge Nibble Transmission) interface realizes a cost-efficient alternative to an analog sensor in the system and a real digital transmission between sensor and ECU. Similarly, PSI5 (Peripheral Sensor Interface) is designed to meet the requirements of a universal, highly reliable automotive sensor interface at the lowest possible implementation costs.
