Abstract
Abstract A circuit for throttle position sensor data shared between controller with dissimilar grounds and to provide reading the output of the throttle position sensor with one of the controllers by referencing the output to the ground of that controller to generate an absolute throttle position sensor reading; and reading the output of the throttle position sensor with another controller via a differential amplifier to generate a relative throttle position sensor reading.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
99 words
Between electronic controllers, with dissimilar grounds, on a vehicle, including an engine control unit and a transmission control unit, a battery and a throttle position sensor, a circuit to share a signal from said throttle position sensor comprising: means for reading the output of said throttle position sensor with one of said controllers by referencing the output to the ground of that controller to generate an absolute throttle position sensor reading; and means for reading the output of said throttle position sensor with the other said controller via a differential amplifier to generate a relative throttle position sensor reading.
Claim 2
Dependent Claim
