The invention relates to a vehicle safety headrest, a headrest controller of the vehicle safety headrest and a control method of the vehicle safety headrest. The vehicle safety headrest comprises a collision monitor unit, a distance detector unit, a headrest driving mechanism and a control loop, wherein the collision monitor unit is in communication connection to and/or electric connection to the control loop and is used for predicting a probable rear-end collision accident; the distance detector unit is in communication connection to and/or electric connection to the control loop and is used for detecting the position states of a headrest and a passenger head and a contact state between the headrest and the passenger head; the headrest driving mechanism is used for moving a part or all of a seat headrest to the passenger head; the control loop controls, is connected to the headrest driving mechanism and is used for controlling the movement and locking of the headrest driving mechanism. The headrest moving distance can be changed according to the position of the passenger head during rear-end collision, and a passenger does not feel discomfort caused by the headrest; meanwhile, after the collision process ends, the headrest can automatically return to the primary position, and the problem caused when the headrest does not return to the primary position after the collision is avoided.
