The invention discloses a hidden type vehicle door handle control device, system and method. The hidden type vehicle door handle control device comprises a microcontroller and a first driving unit electrically connected with the microcontroller, and the microcontroller is used for controlling the first driving unit to output a driving signal according to a vehicle door handle unfolding or retracting instruction received from a CAN bus, driving a vehicle door handle motor to unfold or retract a vehicle door handle, diagnosing the working condition of the vehicle door handle motor in the process of unfolding or retracting the vehicle door handle, and sending fault information to the CAN bus for alarming and stopping driving if an abnormal working condition occurs. According to the hidden type vehicle door handle control device, the structure is simple, interaction control is carried out through existing CAN information on a vehicle, and cost is greatly saved; the device has an overcurrent short-circuit overheating diagnosis function, when the load has an overcurrent short-circuit fault, output is automatically cut off to protect the motor, and fault positioning and load updating and maintenance are facilitated; and the ice breaking capacity of the vehicle door handle is improved, and the vehicle door handle is prevented from being frozen by ice and snow in winter.
本发明公开一种隐藏式车门把手控制装置、系统及控制方法,其中,隐藏式车门把手控制装置包括:微控制器和与其电连接的第一驱动单元,所述微控制器用于根据从CAN总线接收车门把手展开或回缩的指令,控制所述第一驱动单元输出驱动信号,驱动车门把手电机以使车门把手展开或回缩,并在车门把手展开或回缩过程中诊断车门把手电机的工况,如果发生异常工况则发送故障信息至CAN总线报警并停止驱动。本发明架构简单,通过车上现有的CAN信息进行交互控制,非常节约成本;自带过流短路过热诊断功能,在负载发生过流短路过故障时,自动切断输出对电机进行保护,方便故障的定位及负载的更新维护;提高了车门把手破冰能力,避免冬天被冰雪冻住。
