The invention relates to the technical field of electric wheel dump trucks, and provides a bus type electronic throttle driving device and method for an electric wheel dump truck, the bus type electronic throttle driving device comprises a speed reduction and execution part, a stepping motor, a position feedback, a stepping motor driver and a driving controller, and the driving controller is in communication connection with a whole truck controller through a bus; the driving controller outputs a control signal, the stepping motor driver outputs a driving signal according to the control signal, and the stepping motor is driven after driving torque is increased through the speed reduction and execution part; the driving controller is configured to convert the position feedback signal and the accelerator given signal into digital signals which are in a linear relation with the opening degree of the throttle valve, and the position feedback signal and the accelerator given signal are converted into the digital signals to generate a control signal. Bus control is adopted, control over the accelerator of the unmanned bicycle is conveniently achieved, the adjustment allowable error is set, and heating of the motor and a driver caused by frequent adjustment of the accelerator motor is avoided.
本公开涉及电动轮自卸车技术领域,提出了用于电动轮自卸车的总线型电子油门驱动装置及方法,包括减速与执行部分、步进电机、位置反馈、步进电机驱动器以及驱动控制器,所述驱动控制器与整车控制器通过总线通信连接;驱动控制器输出控制信号,步进电机驱动器根据控制信号输出驱动信号,并通过减速与执行部分增加驱动力矩后驱动步进电机;驱动控制器被配置为将位置反馈信号以及油门给定信号转化为与节气门的开度之间成线性关系的数字信号,根据位置反馈信号以及油门给定信号转化为数字信号生成控制信号。本公开采用总线控制,便于实现无人驾驶自行车对油门的控制,设置调节容许误差,避免油门电机的频繁调节导致的电机和驱动器发热。
