Abstract
Vehicle driveability is very much dominated by performance of its powertrain and in transient driving situations conditions. This paper aims to evaluate the current methodology for driveability performance parameters, and illustrate the evaluation methods. The evaluation of driveability performance for an in-use microbus fueled diesel/CNG is shown. The longitudinal acceleration response characteristics as critical factors are analyzed. Data are available from laboratory chassis dynamometer tests in which particle number values from the microbus of a range of capacity and technologies have been measured. The measurements were conducted on a Toyota HIACE microbus using the European legislated driving cycle (New European Driving Cycle, NEDC). The results indicate that the approach can estimate precisely the driveability parameters appear to be improved when the microbus is powered by diesel charged engine. The longitudinal acceleration response is found to be a crucial factor for microbus driveability development to build unique driveability brand.
