The invention discloses a control method of a fuel cell hydrogen energy automobile energy feedback control system, the energy feedback control system comprises a VCU module, an MCU module, an IVI module, an IC module, an ESC module and a BMS module, and the control method of the energy feedback control system comprises braking energy feedback, sliding energy feedback and energy flow display. If the braking energy feedback function activation condition or the sliding energy feedback function activation condition is met, activating a braking energy feedback function or a sliding energy feedback function, calculating a braking target feedback torque based on the current state of the vehicle, controlling a motor controller to enter a power generation program, and controlling a BMS to enter a battery feedback management program; and executing braking energy feedback torque output. And if any condition of brake energy feedback quitting is met, the vehicle quits the brake energy feedback function. The control method of the energy feedback control system effectively manages the energy feedback control system of the fuel cell vehicle and a whole set of energy feedback logic control strategy, so that an energy feedback function is effectively realized.
本发明公开了一种燃料电池氢能汽车能量回馈控制系统的控制方法,能量回馈控制系统包括VCU模块、MCU模块、IVI模块、IC模块、ESC模块和BMS模块,能量回馈控制系统的控制方法包括制动能量回馈、滑行能量回馈和能量流显示。若满足制动能量回馈功能激活条件或滑行能量回馈功能激活条件,则激活制动能量回馈功能或滑行能量回馈功能,基于车辆当前状态计算制动目标回馈扭矩,控制电机控制器进入发电程序,BMS进入电池回馈管理程序,执行制动能量回馈扭矩输出。若满足制动能量回馈退出任一条件,车辆退出制动能量回馈功能。该能量回馈控制系统的控制方法有效的管理了燃料电池汽车能量回馈控制系统,整套的能量回馈逻辑控制策略,使能量回馈功能得以有效实现。
