Title
(EN) OPTIMIZATION OF REGENERATIVE BRAKING EFFICIENCY IN HYBRID VEHICLE
(ZH) 混合动力车辆中的再生制动效率优化
Abstract
(EN) The invention relates to optimization of the regenerative braking efficiency in a hybrid vehicle. An autonomous or semi-autonomous vehicle is provided that is capable of braking itself without a driver depressing the brake pedal. The vehicle has a powertrain that includes an engine, a transmission, and a motor with a connected battery to provide regenerative braking capabilities. Friction brakes are provided to apply when necessary, such as when the battery has a high state of charge and further regenerative braking would overcharge the battery. The braking may be activated in response to a sensor detecting a distance to an object in front of the vehicle. A vehicle controller is programmed to automatically control amounts of regenerative braking and friction braking during a braking eventbased on a comparison between a regenerative torque limit of the powertrain and a desired brake torque over the brake event to safely brake the vehicle during the brake event.
(ZH) 本公开涉及混合动力车辆中的再生制动效率优化。提供了一种自主或半自主车辆,其能够在驾驶员不踩下制动踏板的情况下自己制动。车辆具有包括发动机、变速器和与电池连接的马达的动力传动系统,以提供再生制动能力。提供摩擦制动器,以在必要时应用,诸如在电池具有高荷电状态并且进一步的再生制动会对电池过度充电时。所述制动可响应于传感器检测到距车辆前方的物体的距离而被激活。车辆控制器被配置为:基于在制动事件内动力传动系统的再生扭矩限制与期望的制动扭矩之间的比较,自动控制制动事件期间的再生制动和摩擦制动的量,以在制动事件期间安全地制动车辆。
