Projection method of target area where vehicle moves, hmi computer system and vehicle

Abstract

The invention relates to a projection method of a moving target area of ​​a vehicle, an HMI computer system and a vehicle. The method includes: acquiring target area information, vehicle positioning information and information of an automatic driving system; based on the target area information, vehicle positioning information and a plurality of projections system information, determine the activated projection device, and generate a PTZ control command; generate projection content based on the target area information and the information of the automatic driving system; send the projection content to the activated projection device, and send the activated projection device to the cloud The platform sends the PTZ control command. The present invention installs multiple projection systems on the vehicle, selects an activated projection device based on target area information, vehicle positioning information, and multiple projection system information, and performs projection in the target area, and the projection content locks the target area, so that other vehicles or Pedestrians can intuitively understand the target area where the autonomous vehicle will move, thereby reducing the risk of accidents.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automatic driving, and in particular, to a method for moving a vehicle to a target area, an HMI computer system, and a vehicle. Background technique [0002] At present, some models support on-board projectors. The on-board projector is fixed on the vehicle, such as in the headlight, and projects a fixed pattern of light spots on the ground. The area of ​​the light spot can represent the target area where the vehicle moves. [0003] However, since the vehicle-mounted projector is fixed on the vehicle, the projected area is fixed relative to the vehicle. In scenarios where the vehicle needs to be moved to the target area, such as reversing into the garage, when the vehicle is reversing, the relative position of the vehicle and the parking area changes. Therefore, the area projected by the on-board projector cannot lock the parking area. [0004] It can be seen that the target area th...

[0003] However, since the on-board projector is fixed on the vehicle, the projected area is fixed relative to the vehicle

However, in the scene where the vehicle needs to be moved to the target area, such as reversing into the garage, the relative position of the vehicle and the parking area changes when the vehicle is reversing. Therefore, the area projected by the on-board projector cannot lock the parking area.

[0004] It can be seen that the target area where the vehicle will move to cannot be known by other vehicle drivers, other autonomous vehicles, and pedestrians, which increases the driving burden of other vehicle drivers and the risk of accidents
