Assessment of passenger car driveability with use of two axis accelerometer mounted on car body
AbstractIn this paper an assessment of passenger car drivability with use of two axis accelerometer mounted on car body is shown. The car boy acceleration measurement was analyzed in four areas: sensor accuracy, accelerometer and working engine related noises, sensor coordinate system reorientation during instantaneous acceleration or braking and disturbances caused by the road irregularities. Simulations and experimental results proved that car acceleration measurement is disturbed by the car suspension reaction when it accelerating or braking and road irregularities.
