Rotational speed/tip sensor
First Claim
1. In a two-wheeled motor vehicle having an engine,sensor means for simultaneously detecting the attitude of the motor vehicle relative to a selected frame of reference and the speed of the engine comprising:
- a. housing means for attaching to the engine;
b. tip sensor means assembled in the housing means for detecting the attitude of the vehicle relative to the selected frame of reference;
c. speed sensor means assembled in the housing means for detecting the speed of the engine; and
d. control means for controlling the engine in response to the attitude of the motor vehicle relative to the selected frame of reference as detected by the tip sensor means.

Abstract
A rotational speed/tip sensor combines a tip sensor and a speed sensor in one compact package for use on a motorcycle. The tip sensor includes a disk and a sensing device that detects the absence or presence of the disk in the apex of a V-groove. If the motorcycle tips over, the disk rolls out of the V-groove apex and actuates the tip sensing device to open a circuit through a speed sensing device and thereby shut down the motorcycle engine. The tip and speed sensors are assembled to a housing that is mounted to the engine. Only three wires are used to connect both the tip sensing device and the speed sensing device to the engine control.

9. A rotational speed/tip sensor for controlling the engine of a two-wheeled motor vehicle comprising:
-
a. first sensor means for detecting the attitude of the two-wheeled motor vehicle relative to vertical; b. second sensor means for detecting the engine speed; c. housing means mounted to the engine for receiving the first and second sensor means; and d. control means for shutting down the engine in response to the first sensor means detecting a predetermined attitude of the two-wheeled motor vehicle relative to the vertical. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of controlling the engine of a two-wheeled motor vehicle comprising the steps of:
-
a. mounting a housing to the two-wheeled motor vehicle engine; b. assembling a tip sensor in the housing; c. assembling a speed sensor in the housing; d. operating the tip sensor to close an electrical circuit through the speed sensor and enabling running of the engine in response to the two-wheeled motor vehicle being in a first attitude relative to a selected frame of reference; and e. operating the tip sensor to open the electrical circuit through the speed sensor and shutting down the engine in response to the two-wheeled motor vehicle being in a second attitude relative to the selected frame of reference. - View Dependent Claims (16, 17, 18)
