The invention relates to the technical field of electric power steering systems, in particular to a motor active speed reduction and safe turn-off method for an EPS controller. Compared with the prior art, a system strategy is added, so that active speed reduction and safe turn-off of the motor are realized under the condition that an existing circuit structure is not changed, and the MOSFET is prevented from being broken down and damaged. According to the invention, the cost of safe turn-off is reduced, and the process is simplified.

    本发明涉及电动助力转向系统技术领域,具体地说是一种用于EPS控制器的电机主动降速及安全关断方法。本发明同现有技术相比,增加了系统策略,从而在不改变现有电路结构的情况下,实现电机主动降速及安全关断,避免了MOSFET将被击穿损坏。本发明降低了安全关断的成本、也简化了工艺。
