Abstract
An automotive sensor development process is discussed in this
paper from the viewpoint of whether it is suitable for achieving
new sensors having technological competitiveness. A concrete
example of the application of this development process to
automotive sensors is presented to demonstrate that it produces
technologically competitive sensors.
In the first section, a general process is proposed for
automotive sensor development. The fundamental concepts underlying
this process are summarized below. 1. An analysis of the object to
be measured is the starting point for sensor development. This
analysis is carried out from four perspectives: (1) the measurement
of phenomena for which an electronic system is technologically
advantageous; (2) the mechanism of the object to be measured; (3)
the characteristic behavior of the object; and (4) the special
features of the object. And 2. The analysis consists of thee
essential steps: (1) selection of the most suitable measuring
position; (2) selection of the best measuring method; and (3)
selection of the best measuring device.
Taking as an example, the development of an ultrasonic vehicle
ground speed sensor in the second section, it is shown that the
proposed process is suitable for achieving technologically
competitive sensors in three steps: (1) determination of the actual
development process; (2) development of technologies to overcome
the technological issues involved; and (3) verification of the
technological competitiveness of new sensor.
