<p>The vehicle control system incorporates an accelerometer (12) which is particularly adapted for use in vehicles due to its readily compensated temperature sensitivity and stable zero g bias. The accelerometer for use in the vehicle control system includes a hermetically sealed enclosure (20) containing a fluid and two temperature sensing elements (22, 24) positioned within the enclosure. When the fluid within the enclosure is heated the convective flow pattern within the enclosure is affected by acceleration of inclination of the enclosure. This change in the convective flow pattern is measured by measuring a temperature difference between the temperature sensing elements to determine the acceleration of the enclosure. The resistance of the temperature sensing elements is controlled during production of the accelerometer by applying a current to the temperature sensing elements in an oxidizing atmosphere to cause oxidation of the temperature sensing elements and removing the current when a desired resistance is achieved.</p> |
