The invention discloses a method and a device for determining equivalent specific fuel consumption of a hybrid vehicle. The method comprises the following steps: acquiring a plurality of vehicle speed torque points and a plurality of rotating speed torque points; wherein each vehicle speed torque point corresponds to a vehicle speed and a wheel side torque; each rotating speed torque point corresponds to one engine rotating speed and one engine torque; for any vehicle speed torque point and any rotating speed torque point, based on the vehicle speed torque point and the rotating speed torque point, determining engine power, wheel side required power, battery driving power in an electric driving stage and charging total power in a charging stage under preset working conditions; and obtaining the equivalent specific fuel consumption of the vehicle based on the engine power, the battery driving power, the charging total power and the wheel side demand power. The obtained equivalent specific fuel consumption can provide reference for fuel consumption initial simulation, the accuracy of follow-up fuel consumption simulation is improved, and reference is provided for determining a gear shifting map of a vehicle.

    本发明公开了一种混合动力车辆的等效比油耗确定方法及装置,其中方法包括:获取多个车速扭矩点和多个转速扭矩点;其中,每个车速扭矩点对应一车辆车速和一轮边扭矩;每个转速扭矩点对应一发动机转速和一发动机扭矩;针对任一车速扭矩点和任一转速扭矩点,基于车速扭矩点与转速扭矩点,确定预设工作工况条件下发动机功率、轮边需求功率、电驱阶段的电池驱动功率和充电阶段的充电总功率;基于发动机功率、电池驱动功率、充电总功率和轮边需求功率,获得车辆的等效比油耗。本发明获得的等效比油耗可为油耗初期仿真提供参考,提高后续油耗仿真的准确性,还为确定车辆的换挡地图提供参考。
