  "textContent": "A hill stop control method, apparatus and system for a four-wheel drive vehicle, and a vehicle, which belong to the technical field of automobiles. The method includes: when it is determined that a vehicle is in a park brake state, determining, by acquiring the current parameter of the vehicle, whether the vehicle is in a working condition of being prone to sliding; and when it is determined that the vehicle is in a working condition of being prone to sliding, controlling a mode switch of a transfer case to switch the current drive mode to a high-speed four-wheel drive mode having a stronger brake force or a low-speed drive mode. In this way, the automatic switching of a drive mode is realized without changing a brake system; and when stopped on a hill, friction forces between tires and the ground are increased, thereby effectively reducing the risk of sliding down a hill, and effectively solving the problem of a vehicle being at risk of sliding down a hill due to braking rear wheels only by using an EPB or a hand brake when a four-wheel drive vehicle is in a high-speed two-wheel drive mode and is parked on a road surface having a certain slope.",
