    摘要： A hill stop control 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.

    摘要： A monitoring method and device for determination of a gear-stick position, a vehicle control unit, and a vehicle. The monitoring method for determination of a gear-stick position includes: acquiring a first actual gear-stick position and a first acceptable gear-stick position calculated by a functional layer; calculating a second actual gear-stick position according to a gear-stick position signal; determining whether the first actual gear-stick position and the second actual gear-stick position are consistent; in case that the first actual gear-stick position and the second actual gear-stick position are consistent, determining whether the first acceptable gear-stick position is valid; and in case that the first actual gear-stick position and the second actual gear-stick position are inconsistent or the first acceptable gear-stick position is invalid, controlling the vehicle to enter a safe state. The present application can ensure safe driving of a vehicle.

    摘要： A driving mode control method, apparatus, device, program and storage medium, which relates to the technical field of electronic control, and is for a control platform, the method includes: acquiring a location information sent by a target vehicle, wherein the location information comprises a target location; determining a status data of at least one sample vehicle pre-stored by the control platform based on the target location, wherein the sample vehicle is a vehicle which has travelled through the target location; determining a target driving mode based on the status data of the sample vehicle, and sending the target driving mode to the target vehicle, such that the target vehicle travels in the target driving mode. This disclosure enables the target vehicle to travel in the target driving mode. The driver needs not to manually switch the driving mode, and the accuracy and convenience of controlling the drive mode are improved.
