The invention relates to the technical field of multifunctional all-terrain vehicles, and particularly discloses a hybrid electric drive UTV cross-country running maximum power control method which comprises the steps that a volt-ampere characteristic curve of a storage battery, a maximum equipower curve of a generator and the current opening degree of an accelerator are obtained; when the current opening degree of the accelerator is larger than a preset threshold value, the generator is controlled to output discharging current according to the maximum equipower curve, and meanwhile the storage battery is controlled to output discharging current according to the volt-ampere characteristic curve of the storage battery; and when the discharge current output by the generator and the discharge current output by the storage battery supply power to the driving motor together, the driving motor is controlled to carry out maximum torque output in a full time domain so as to realize maximum power control of cross-country running of the multifunctional all-terrain vehicle UTV. The efficiency of the generator set can be brought into full play, it is guaranteed that power output power is sufficient, and good cross-country maneuvering performance of the platform is guaranteed.
本发明涉及多功能全地形车技术领域,具体公开了一种混合电驱动UTV越野行驶最大动力控制方法,包括:获取蓄电池的伏安特性曲线、发电机的最大等功率曲线以及油门的当前开度;当油门的当前开度大于预设阈值时,控制发电机按照最大等功率曲线输出放电电流,同时控制蓄电池按照蓄电池的伏安特性曲线输出放电电流;当发电机输出的放电电流和蓄电池输出的放电电流共同为驱动电机供电时,控制驱动电机在全时域进行最大扭矩输出,以实现多功能全地形车UTV越野行驶的最大动力控制。本发明能够充分发挥发电机组的效能,保证电源输出动力充足,保证平台良好的越野机动性能。
