1. A system for determining characteristics of a motor vehicle, the system comprising:
- a first sensor adapted for attachment to the vehicle in a first mounted state that constrains movement of the sensor relative to the vehicle, and the first sensor being configured to generate a first signal;
an electronic control unit in electrical communication with the first sensor for receiving the first signal, the electronic control unit being configured determine if the first sensor is in a second state that is less constrained relative to the vehicle than the first mounted state, based on features in the first signal.

Abstract
A system includes a remote sensor and an electronic control unit. The electric control unit determines if the remote sensor is detached from the vehicle structure by analyzing the sensor signal from the remote sensor. The electronic control unit may compare the sensor signal to other signals. For example, from another remote sensor or an on-board sensor contained within the electronic control unit. The electronic control unit identifies features in the sensor signal indicative of the remote sensor being detached from the vehicle.

14. A system for determining characteristics of a motor vehicle, the system comprising:
-
a first sensor adapted for attachment to the vehicle in a first mounted state that constrains movement of the first sensor relative to the vehicle, and the first sensor being configured to measure a first acceleration signal;
an electronic control unit in electrical communication with the first sensor for receiving the first acceleration signal, the electronic control unit being configured to perform a comparison between at least one transient signal in the first acceleration signal and a second acceleration signal, the electronic control unit being adapted to determine if the first sensor is in a second state that is less constrained relative to the vehicle than the first mounted state, based on the comparison. - View Dependent Claims (15, 16, 17, 18, 19, 20)
