Standard driving cycles are usually used to compare vehicles from distinct regions, and local driving cycles reproduce more realistic conditions in specific regions. In this article, we employed a simple methodology for developing local driving cycles and subsequently performed a kinematic and energy analysis. As an application, we employed the methodology for cars and motorcycles in Recife, Brazil. The speed profile was collected using a smartphone (1 Hz) validated against a high precision global positioning system (10 Hz), presenting a mean absolute error of 3 km/h. The driving cycles were thus developed using the micro-trip method. The kinematic analysis indicated that motorcycles had a higher average speed and acceleration (32.5 km/h, 0.84 m/s2) than cars (22.6 km/h, 0.55 m/s2). As a result of the energy analysis, it was found that inertia is responsible for most of the fuel consumption for both cars (59%) and motorcycles (41%), but for motorcycles the aerodynamic drag is also relevant (36%). With regards to fuel consumption, it was found that the standard driving cycle used in Brazil (FTP-75; 2.47 MJ/km for cars and 0.84 MJ/km for motorcycles) adequately represents the driving profile for cars (2.46 MJ/km), and to a lesser extent motorcycles (0.91 MJ/km) in off-peak conditions. Finally, we evaluated the influence of the vehicle category on energy consumption, obtaining a maximum difference of 38% between a 2.0 L sports utility vehicle and a 1.0 L hatchback.

开发和分析本地行驶循环的简单方法应用于巴西累西腓的汽车和摩托车研究

通常使用标准驾驶循环来比较来自不同区域的车辆,而本地驾驶循环则在特定区域重现更为实际的条件。在本文中,我们采用了一种简单的方法来开发本地驾驶循环,随后进行了运动学和能量分析。作为应用,我们在巴西累西腓采用了汽车和摩托车的方法。速度曲线是使用经过高精度全球定位系统(10 Hz)验证的智能手机(1 Hz)收集的,平均绝对误差为3 km / h。因此,使用微行程方法开发了行驶周期。运动学分析表明,摩托车的平均速度和加速度(32.5 km / h,0.84 m / s 2)比汽车(22.6 km / h,0.55 m / s 2)高。)。能量分析的结果表明,惯性是汽车(59%)和摩托车(41%)的大部分燃料消耗原因,但对于摩托车,空气阻力也很重要(36%)。关于燃料消耗,发现巴西使用的标准行驶周期(FTP-75;汽车为2.47 MJ / km,摩托车为0.84 MJ / km)足以代表汽车的行驶曲线(2.46 MJ / km),以及在非高峰条件下的电单车(0.91 MJ / km)。最后,我们评估了车辆类别对能耗的影响,得出了2.0升运动型多用途车与1.0升掀背车之间的最大差异为38%。
