Body incline sensor for a motorcycle
First Claim
1. A body incline sensor for a vehicle, comprising:
- a case mountable on a body of the vehicle;
a weight mounted in said case in such a manner as to freely swing in a width direction of the vehicle;
incline angle detecting means for detecting the swing of said weight through a predetermined angle; and
inclined state transmitting means for transmitting an inclined state signal when it is determined that the body of the vehicle is in an inclined state from said incline angle detecting means detecting said weight, and the inclined state continues over a predetermined length of time.

Abstract
A body incline sensor includes an erroneous detection preventing circuit for transmitting an inclined state signal by determining that a body is in an inclined state when an incline angle detector detects a weight, and a state so detected continues over a predetermined length of time. In the event that the incline angle detector does not detect a weight within a predetermined length of time due to an inertia force resulting when a body is rolling, no inclined state signal is transmitted from an inclined state transmitter, whereby the erroneous detection of the incline of the body can be prevented, the accuracy with which the incline of the body is detected being thus improved. In addition, in the event that the incline angle detector is constituted by the weight and magnets mounted on the weight and reed switches adapted to be switched on by the magnets, and in the event that the inclined state transmitter is constituted by a simple electric circuit, the production costs of the body incline sensor can be suppressed.

13. A method of detecting the incline of a vehicle, comprising the steps of:
-
mounting a body incline sensor on a body of the vehicle, the body incline sensor including a case, a weight mounted in said case in such a manner as to freely swing in a width direction of the vehicle, an incline angle detector, and an inclined state transmitter;
detecting the swing of said weight through a predetermined angle with said incline angle detector; and
