The invention relates to an electric vehicle coordination control method and device, and relates to the technical field of vehicle control, and the method comprises the following steps: when a target vehicle satisfies a hydraulic compensation identification working condition, obtaining an electric feedback target torque and a hydraulic compensation target torque based on a system feedback capability and an original demand target feedback torque; and based on the hydraulic compensation target torque and the electric feedback target torque, the electric drive torque and the hydraulic brake torque are controlled in a time-sharing and segmented coordinated mode in combination with vehicle dynamics. Vehicle coordination control is completed by coordinating electric drive and hydraulic compensation torque, auxiliary coordination is carried out in the vehicle running process, and therefore driving safety and comfort are guaranteed.
本申请涉及一种电动汽车协调控制方法及装置,涉及车辆控制技术领域,该方法包括以下步骤:当目标车辆满足液压补偿识别工况时,基于系统回馈能力以及原始需求目标回馈扭矩,获得电回馈目标扭矩以及液压补偿目标扭矩;基于液压补偿目标扭矩以及电回馈目标扭矩,结合车辆动力学,分时分段协调控制电驱扭矩和液压制动扭矩。本申请通过协调电驱和液压补偿扭矩完成车辆协调控制,在车辆行驶过程中进行辅助协调,以保障驾驶安全性和舒适性。
