建立了重型汽车能耗预测的数学模型。它包括重型车辆能耗的重要因素，即发动机和传动系统性能、附件造成的损失、空气动力阻力、滚动阻力、道路坡度和驾驶员行为。开发了新的低成本测试方法来确定发动机和传动系统的特性。一个简单的驱动循环被用来验证模型。该模型能够预测的燃料使用的37吨拖拉机-半挂车车辆超过4公里的驱动cycle在1%.This文件表明，准确和可靠的车辆基准和模型参数测量可以实现没有昂贵的设备开销，如发动机和底盘测功机。
A mathematical model is developed to predict the energy consumption of a heavy vehicle. It includes the important factors of heavy-vehicle energy consumption, namely engine and drivetrain performances, losses due to accessories, aerodynamic drag, rolling resistance, road gradients, and driver behaviour. Novel low-cost testing methods were developed to determine engine and drivetrain characteristics. A simple drive cycle was used to validate the model. The model is able to predict the fuel use for a 37 t tractor–semitrailer vehicle over a 4 km drive cycle within 1 per cent. This paper demonstrates that accurate and reliable vehicle benchmarking and model parameter measurement can be achieved without expensive equipment overheads, e.g. engine and chassis dynamometers.
