System and method for vehicle diagnostics
First Claim
1. A method for diagnosing whether one or more components of a vehicle are operating abnormally, comprising:
- arranging a plurality of sensors on a vehicle;
in a training stage,receiving output from the sensors during normal operation of the components,adjusting each component to induce abnormal operation thereof and receiving output from the sensors during the induced abnormal operation, anddetermining which sensors provide data about abnormal operation of each component based on analysis of the output from the sensors during normal operation and during induced abnormal operation of the component; and
during operation of the vehicle,receiving output from the sensors; and
determining whether any of the components are operating abnormally by analyzing the output from those sensors which have been determined to provide data about abnormal operation of that component.

Abstract
Method and system for diagnosing whether vehicular components are operating abnormally based on data obtained from sensors arranged on a vehicle. In a training stage, output from the sensors during normal operation of the components is obtained, each component is adjusted to induce abnormal operation thereof and output from the sensors is obtained during the induced abnormal operation. A determination is made as to which sensors provide data about abnormal operation of each component based on analysis of the output from the sensors during normal operation and during induced abnormal operation of the components. During operation of the vehicle, the output from the sensors is obtained and analyzed, e.g., by inputting it into a pattern recognition algorithm or neural network generated during the training stage, in order to output an indication of abnormal operation of any components being diagnosed.

14. A vehicle including a system for diagnosing whether one or more components of a vehicle are operating abnormally, comprising:
-
a plurality of sensors arranged on the vehicle; and a processor coupled to said sensors and including a pattern recognition algorithm which receives output from said sensors and determines whether each component is operating abnormally by analyzing output from specific ones of said sensors determined to provide data about abnormal operation of that component, said pattern recognition algorithm being generated by analyzing output from said sensors during normal operation of the components and during induced abnormal operation of the components. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for diagnosing whether one or more components of a vehicle are operating abnormally, comprising:
-
arranging a plurality of sensors on a vehicle; in a training stage, receiving output from the sensors during normal operation of the components, adjusting the components to induce abnormal operation thereof and receiving output from the sensors during the induced abnormal operation, and generating a neural network which operatively determines abnormal operation of the components, the neural network being generated from the output from sensors during normal operation and the output from the sensors during induced abnormal operation of the components; and during operation of the vehicle, receiving output from the sensors; and providing data derived from the output from the sensors to the neural network which outputs an indication of abnormal operation of any of the components. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
