Powertrain & Vehicle - Driveability OptimizationCustomer RequirementsDriveability of trucks and the driver's comfort are gaining importance for vehicle development as fleet owners have realised that trucks are operated more efficiently when the driver's working place is improved. In addition, in a competitive market place, the end customer's needs and quality expectations become more demanding and the vehicle has to be developed in a shorter time.
So far, the complex evaluation of vehicle properties such as driveability and comfort has been the task of test drivers, filling questionnaires with their subjective judgement. Only a few objective measurements have been performed, such as for interior cab noise or vibration measurements of the cabin and at the driver’s seat.
Objectively assessing the performance status of the new truck during the development period and comparing it with competitor products is an essential task not only for the management but also for the development engineers. Knowing the strong and weak points of the design defines the targets and so finally helps to improve the product.
For creating such a comprehensive product overview many individual criteria need to be measured, analysed and evaluated.
