The invention relates to the technical field of semi-trailer tractor systems, and discloses a semi-trailer tractor saddle protection system and method.The protection system comprises a stress sensor arranged on a saddle and connected to a VCU controller; the air storage cylinder is connected with the tractor parking air chamber and the trailer parking air chamber through a plurality of air pipes, a plurality of electromagnetic valves are arranged among the air pipes, and all the electromagnetic valves are connected to the VCU controller; the VCU controller is used for controlling the multiple electromagnetic valves to conduct inflation and deflation adjustment when the vehicle speed is zero and the stress value obtained by the stress sensor is larger than or equal to a set stress threshold value, and braking releasing of the trailer is achieved. And the controller is also used for performing inflation and deflation adjustment to recover trailer braking after the trailer releases braking and when the stress value acquired by the stress sensor is smaller than a set stress threshold value. According to the protection system and protection method for the saddle of the semi-trailer tractor, when the extrusion stress borne by the saddle is too large, trailer braking is relieved, and the problem that the connecting position of the saddle and the frame is prone to deformation and damage is solved.

    本申请涉及半挂牵引车系统技术领域,公开了一种半挂牵引车鞍座的保护系统及保护方法,保护系统包含:设置于鞍座的应力传感器,其连接于VCU控制器;储气筒,其通过若干气管连接牵引车驻车气室和挂车驻车气室,若干气管间设置若干电磁阀,所有电磁阀均连接于VCU控制器;VCU控制器用于在车速为零且应力传感器获取的应力值大于等于设定应力阈值时,通过控制多个电磁阀进行充放气调节,实现挂车解除制动;还用于在挂车解除制动后且应力传感器获取的应力值小于设定应力阈值时,进行充放气调节恢复挂车制动。本申请半挂牵引车鞍座的保护系统及保护方法,在鞍座受到挤压应力过大时,解除挂车制动,解决鞍座及车架连接处易变形损坏的问题。
