Magnetic Field Sensor and Its Application to Automobiles 800123

A direction sensor, which measures the terrestrial magnetism and its application to automobiles are discussed. The flux gate type sensor proposed in this paper is sensitive and stable enough for automotive use. A new technique to compensate the car body magnetism is also discussed. The heading display system which consists of a direction sensor, a control circuit and a display device works quite well. A Trip Computer with more attractive features can be easily embodied by applying this sensor.
