The invention provides a tractor safety detection device which is used in the technical field of tractors, and particularly relates to a tractor safety detection device which comprises a secondary locking structure capable of preventing a trailer pin shaft from being separated from a tractor saddle. When the trailer pin shaft tends to be separated from the saddle, the trailer pin shaft can abut against the secondary locking structure and enable the secondary locking structure to generate displacement; and the locking state detection device can detect the displacement of the secondary locking structure and can send a detection signal to the tractor control unit. The safety detection device for the tractor can prevent the trailer pin shaft from being separated from the saddle of the tractor, and can send a detection signal that the locking mechanism is not completely locked to the tractor control unit. The invention further provides a tractor and a safety detection method, the tractor control unit of the tractor can judge the locking state of the trailer pin shaft and the saddle according to a detection signal of the locking state detection device, and whether the tractor power unit is controlled to brake and decelerate or not can be determined according to the locking state.

    本申请提供了一种牵引车安全检测装置,用于牵引车技术领域,具体为一种牵引车安全检测装置,包括能阻止挂车销轴从牵引车鞍座内脱出的二次锁止结构,挂车销轴有从鞍座内脱出趋势时能抵接在二次锁止结构上并使二次锁止结构产生位移;还包括能检测二次锁止结构的位移,并能将检测信号发送至牵引车控制单元的锁止状态检测装置。上述牵引车安全检测装置能够阻止挂车销轴从牵引车的鞍座内脱出,并能向牵引车控制单元发送锁止机构未完全锁止的检测信号。本申请还提供了一种牵引车及安全检测方法,牵引车的牵引车控制单元能根据锁止状态检测装置的检测信号判断挂车销轴和鞍座的锁止状态,并能根据锁止状态决定是否控制牵引车动力单元制动减速。
