Abstract

Application of regenerative braking on electric vehicles has a large impact on several aspects of design, implemented functionalities and overall performances of road vehicles. In particular, multi-quadrant capabilities and improved control performances of modern electric drives can be fully exploited to improve vehicle efficiency, stability and overall environmental impact. Conventional, mechanical friction brakes are currently devoted not only to stop the vehicle but also to the actuation of safety related mechatronics systems such as electronic braking distribution (EBD), AntiBlockierSystem (ABS) and electronic stability control/program (ESC/ESP). The result is an over-actuated system of electrical (electric motors) and mechanical actuators (friction brakes), whose mixed, blended application has to be carefully optimised. In this work a simplified approach is proposed in which concepts transferred from previous studies on high speed trains and autonomous vehicles are re-purposed and adapted in an innovative way to electric road vehicles.

道路电动汽车的制动混合和扭矩矢量控制：一种基于智能扭矩分配的灵活方法

再生制动技术在电动汽车上的应用对道路车辆的设计、实现功能和整体性能等方面产生了很大的影响。特别是，现代电力驱动的多象限能力和改进的控制性能可以充分利用，以提高车辆效率，稳定性和整体环境影响。传统的机械摩擦制动器目前不仅用于停止车辆，而且还用于驱动与安全相关的机电一体化系统，如电子制动分配(EBD)、防阻塞系统(ABS)和电子稳定控制/程序(ESC/ESP)。其结果是电气(电动机)和机械执行器(摩擦制动器)的过度驱动系统，其混合应用必须仔细优化。在这项工作中，提出了一种简化的方法，其中从以前的高速列车和自动驾驶汽车研究中转移的概念被重新利用，并以一种创新的方式适应于电动道路车辆。
