The invention belongs to the technical field of vehicle chassis braking systems, and relates to a commercial vehicle dryer control method which comprises the steps that a drying tank replacement early warning system is started; air compressor displacement information P and air compressor and engine transmission ratio information R are obtained, and EAD-air compressor state information and EEC1-engine rotating speed information are recorded through a whole vehicle CAN network; algorithm control is carried out on the data; logic judgment is carried out on the cumulative sum of the air pumping amount of the stage air compressor; after the accumulated air pumping amount of the air compressor and C12 reach an early warning set value H, the drying tank replacement early warning system prompts to replace the drying tank; and the alarm is eliminated by operating the one-key recovery button. The method is suitable for application of drying tanks with different performances, buttons of different application types are arranged to correspond to the drying tanks with different performances respectively, and the more accurate application effect is guaranteed; an additional processor is not needed, the regeneration gas amount of the dryer is automatically adjusted according to the air pumping amount of the air compressor, and the drying effect in the life cycle of the dryer is guaranteed.
本发明属于车辆底盘制动系统技术领域,涉及一种商用车干燥器控制方法,包括:开启干燥罐更换预警系统;获取空压机排量信息P和空压机与发动机传动比信息R,通过整车CAN网络记录EAD‑空压机状态信息和EEC1‑发动机转速信息;对上述数据进行算法控制;对阶段空压机泵气量累计和进行逻辑判断;空压机泵气量累计和C12达到预警设定值H后,干燥罐更换预警系统提示更换干燥罐;操作一键恢复按钮,消除报警。本发明适应不同性能干燥罐的应用,设置不同应用类型按钮分别对应不同性能干燥罐,保证更准确的应用效果;不需要额外安装处理器,根据空压机的泵气量自动调整干燥器的再生气体量,保证干燥器生命周期内的干燥效果。
