The invention relates to a redundant electronic steering system, comprising: a drive motor including at least two three phases; at least two control units; and a controller for controlling the redundant electronic steering system to switch between at least two channel modes, wherein when the currently used channel mode breaks down, the controller switches the channel mode to another channel mode,and the control units and/or the three phases in the working state in different channel modes are/is different. Therefore, even if the currently used channel mode breaks down, the redundant electronicsteering system can still work normally in another channel mode without failure.
本公开涉及冗余电子转向系统,包括:驱动电机,其包括至少两个三相;至少两个控制单元;以及控制器,用于控制所述冗余电子转向系统在至少两个通道模式间切换,其中,在当前所使用的通道模式发生故障时,所述控制器将该通道模式切换至另一通道模式,其中,不同的通道模式下处于工作状态的控制单元和/或三相不同。由此,即使当前所使用的通道模式发生故障,冗余电子转向系统也仍然能够以未发生故障的另一通道模式正常工作。
