Vehicle pitch and roll angles can be determined by measuring the distance between three car-body points and the road or track surface. This process requires an exact knowledge of the geometric arrangement of the sensors.
Calculation of Pitch and Roll is an iterative process. Therefore, it is not possible to calculate pitch and roll angle independently of each other.
Error estimation shows the influence of the different measurement parameters on the results. The CORREVIT® Pitch and Roll System is designed to precisely determine the position of a vehicle relative to a road or track surface. This advanced measurement system incorporates three optical sensors mounted to a vehicle, each of which provides individual dynamic measurements of the distance between the vehicle and the road or track surface. Several sensor mounting configurations are possible, however it must be noted that each of these configurations requires distinct calculations to determine pitch and roll angles. This overview also provides an analysis of possible sources of error and indicates which of the measurement parameters will have the greatest influence on accuracy.
