The increasing replacement of mechanical parts by x-by-wire systems in automotive applications allows improving driver safety. These systems demand highly dependable sensors that ensure their functionality despite the harsh operating conditions. This means that the sensors should be capable of working continuously despite catastrophic faults and keeping the performance over time. An anisotropic magnetoresistance...
Electronic systems are replacing mechanical parts to improve the safety and performance of the cars. However, the electronic components should be dependable, meaning they should be trusted to work properly over time. AMR sensors are widely used in automotive for angle measurements. Nevertheless, they are affected by performance degradation and catastrophic faults. Both should be handled to guarantee...
Anisotropic Magnetoresistance (AMR) sensors are magnetic sensors often used for angle measurements. The sensor outputs should be two perfect sinusoidal signals that depend on the angle to be measured. However due to non-ideal properties of the sensor, the actual outputs include undesired parameters as offset voltage, amplitude imbalance and harmonics. All of them generate errors in the angle calculation...
Anisotropic Magnetoresistance (AMR) sensors are often used for angle measurements. The sensor outputs consist of two sinusoidal signals that show undesired characteristics as offset voltage, amplitude imbalance and harmonics, which affect the angle measurements. These parameters change due to aging effects, but until now it is considered that these variations do not affect the sensor accuracy. The...
An Anisotropic Magnetoresistance (AMR) sensor is magnetic sensor often used to angle measurements. In case the sensor is configured with two Wheatstone bridges, it provides two sinusoidal outputs useful to calculate the angle of a magnetic field. However, due to non-ideal properties of the sensor, its output signals present undesired characteristics such as offset voltage, amplitude imbalance and...
