中文摘要：
液压制动与电机再生制动互相切换的过渡工况控制是电动汽车复合制动系统控制需要解决的关键技术问题，直接影响到驾驶员的制动感觉与车辆制动舒适性。对此提出一种协调控制策略，包括制动力分配修正和电机力补偿2个模块。制动力分配修正模块针对液压制动力介入、撤出和再生制动力低速撤出3类典型过渡工况修正分配结果；电机力补偿模块利用电机系统迅速准确的响应来补偿液压系统，改善复合系统的响应。对各类典型制动过渡工况进行仿真验证，结果表明，所设计的协调控制策略能有效减小实际总制动力波动和偏差，改善驾驶员的制动感觉和车辆制动舒适性。
英文摘要：
The control in transient conditions when hydraulic brake and regenerative brake switch mutually is the key technical issue about electric vehicle hybrid brake system, which has a direct influence on the braking feel and braking comfort of a driver. A coordination control system has been proposed, including brake force distribution correction module and motor force compensation module. The former fixes the distribution results in hydraulic brake force intervention condition, hydraulic brake force evacuation condition and regenerative brake force low speed evacuation condition. The latter compensates for the hydraulic system with motor system, which has fast and accurate response, thus the response of the whole hybrid system can be improved. Simulation and test results in transient conditions show that the coordination control strategy can effectively reduce the fluctuations and deviations of the total brake force, and improve braking feel and braking comfort of a driver.
