Abstract
A method of detecting the improper mounting of a sensor on a motor vehicle includes monitoring the output signals of the sensor, determining the noise levels in the output signals, and comparing the noise levels from the output signals to a threshold noise value to determine if the sensor is properly mounted. Preferably, the method monitors the output signals of a first sensor and a second sensor, determines the noise levels in the output signals being emitted by each of the sensors, and compares the noise levels of the first sensor to the noise levels of the second sensor to determine if the sensors are properly mounted.

A method of detecting improper mounting of a sensor on a motor vehicle, the sensor emitting output signals, the method comprising:
- monitoring the output signals of the sensor;
- determining noise levels in the output signals;
- and
- comparing the noise levels from the output signals of the sensor to a threshold noise value to determine if the sensor is properly mounted.
A method of detecting improper mounting of a sensor on a motor vehicle, the motor vehicle having a first sensor and a second sensor that each emit output signals, the method comprising:
- monitoring the output signals of the sensors;
- determining the noise levels in the output signals being emitted by each of the sensors;
- and
- comparing the noise levels of the first sensor to the noise levels of the second sensor to determine if the sensors are properly mounted.
A method of detecting improper mounting of an acceleration sensor on a motor vehicle, the motor vehicle having a first acceleration sensor and a second acceleration sensor that each emit acceleration signals, the method comprising:
- monitoring the acceleration signals of the sensors;
- determining the noise levels in the acceleration signals being emitted by each sensor;
- comparing the noise levels of the first sensor to the noise levels of the second sensor to determine if the sensors are properly mounted, comparing the noise levels including:
- comparing the noise levels of the first sensor to a predetermined threshold value and incrementing a first counter when the threshold value is exceeded;
- comparing the noise levels of the second sensor to a predetermined threshold value and incrementing a second counter when the threshold value is exceeded;
- and
- comparing the first and second counters to determine whether one of the sensors may be improperly mounted;
- and
- issuing a warning when a sensor is determined to be improperly mounted.
A method of detecting improper mounting of a sensor on a motor vehicle, the sensor emitting output signals, the method comprising:
- monitoring the output signals of the sensor without inputting a test signal from a test signal generator;
- determining noise levels in the output signals;
- and
- comparing the noise levels in the output signals of the sensor to a threshold noise value to determine if the sensor is properly mounted.
