1. Apparatus for discriminating between types of event on a motor vehicle, comprising:
- a template library storing a plurality of different templates, each template corresponding to an event type; and
a pattern matching processor configured to (i) receive motion sensor data from one or more motion sensors on the motor vehicle, (ii) apply a wavelet transformation to the motion sensor data in order to identify features of transformed motion sensor data, (iii) compare at least one of the identified features of the transformed motion sensor data with templates in the template library and (iv) determine an event type based on the comparison.

Abstract
The disclosure relates to apparatus (300) and automated methods (100, 200) for generating a library of templates (304) corresponding to different known types of motor vehicle event and discriminating between types of event on a motor vehicle. The apparatus (300) comprises the template library (304) and a pattern matching processor (302).

18. An automated method for discriminating between types of event on a motor vehicle, comprising:
-
receiving motion sensor data from at least one motion sensor on the motor vehicle; retrieving a plurality of different templates from a template library, each template corresponding to an event type; applying a wavelet transformation to the motion sensor data in order to identify features of transformed motion sensor data; comparing at least one of the identified features of the transformed motion sensor data with the plurality of different templates; and determining an event type based on the comparison. - View Dependent Claims (21)

19. An automated method for generating a library of templates corresponding to different known types of motor vehicle event, comprising:
-
receiving motion sensor data representative of the different types of motor vehicle event; applying a wavelet transformation to the motion sensor data in order to identify features of transformed motion sensor data; for at least some of the different types of motor vehicle event, determining values of at least one indicative feature, each value corresponding with a particular type of motor vehicle event; providing the library of templates comprising the indicative features and an identifier of the particular type of motor vehicle event with which each value corresponds. - View Dependent Claims (22)
