Abstract

A sensing apparatus for use in a non-horizontally mounted vehicle navigation system includes a chip having a sensing element for detecting a direction based on an amount of a physical quantity applied thereto. The sensing element is arranged in the chip so as to at least partly compensate for the non-horizontal mounting of the vehicle navigation system in which the sensing apparatus is used.

Claims

1. A sensing apparatus for use in a non-horizontally mounted vehicle navigation system, the sensing apparatus comprising a chip including a sensing element for detecting a direction based on an amount of a physical quantity applied thereto, wherein the sensing element is arranged in the chip so as to at least partly compensate for the non-horizontal mounting of the vehicle navigation system in which the sensing apparatus is used.

2. The sensing apparatus according to claim 1, wherein sensing element is arranged to reduce an angle between a detection reference axis thereof and the direction of a physical quantity applied thereto that would otherwise result from the non-horizontal mounting of the vehicle navigation system.

3. A chip for use in a sensing apparatus incorporated in a non-horizontally mounted vehicle navigation system, the chip including a sensing element for detecting a direction based on an amount of a physical quantity applied thereto, wherein the sensing element is arranged in the chip so as to at least partly compensate for the non-horizontal mounting of the vehicle navigation system in which the sensing apparatus is used.

4. The chip according to claim 3, wherein sensing element is arranged to reduce an angle between as detection reference axis thereof and the direction of a physical quantity applied thereto that would otherwise result from the non-horizontal mounting of the vehicle navigation system.
