Description

Control method and device of trailer hook, vehicle and storage medium Technical Field The application relates to the technical field of intelligent automobile electronic control, in particular to a control method and device of a trailer hook, a vehicle and a storage medium. Background The control mode of the existing electric trailer hook mainly depends on a physical switch in a cab or a virtual button on a central control display screen, and the control logic breaks the actual operation position of a user and the control instruction sending position, so that the use convenience is reduced, and potential safety hazards are possibly introduced. Disclosure of Invention The application provides a control method, a device, a vehicle and a storage medium of a trailer hook, wherein multidimensional scene sensing information is introduced and a cooperative triggering condition is set by the method, so that accurate identification and safety verification of the operation intention of the trailer hook are realized, false triggering caused by a single signal source is effectively avoided, on the basis, the self-expanding or retracting action of the trailer hook is completed, and the working mode of relevant functional components at the tail part is further adjusted in a linkage mode, so that a complete vehicle-level function cooperative mechanism taking the state of the trailer hook as a core is constructed.
