Abstract
A method and system for determining the condition of a road travelled by a vehicle includes a sensor for sensing a speed of the vehicle and an accelerometer for sensing a vertical acceleration of the vehicle. A central processing unit have control logic programmed therein determines a first road profile interval having upper and lower threshold values based on the speed of the vehicle and determines the condition of the road based on the vertical acceleration and the first road profile interval.

A method for determining the condition of a road travelled by an automotive vehicle, the method comprising:
- sensing a speed of the vehicle;
- sensing a vertical acceleration of the vehicle;
- determining a first road profile interval having upper and lower threshold values based on the speed of the vehicle;
- and
- determining the condition of the road based on the vertical acceleration and the first road profile interval.
A system for determining the condition of a road travelled by an automotive vehicle, the system comprising:
- a sensor for sensing a speed of the vehicle;
- an accelerometer for sensing a vertical acceleration of the vehicle;
- and
- a central processing unit, coupled to the sensor and the accelerometer, having control logic programmed therein for determining a first road profile interval having upper and lower threshold values based on the speed of the vehicle and determining the condition of the road based on the vertical acceleration and the first road profile interval.
