Problems solved by technology

The designed rearview mirror imaging needs to go through six major transformations to obtain, and the process is relatively cumbersome; and according to the simulation effect diagram, two auxiliary viewports occupy the main viewport and block the sight of the building in front, so the rearview mirror effect not ideal

Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings.

[0051] Such as Figure 1 to Figure 3 As shown, a rearview mirror simulation method for a vehicle simulation driving system, the rearview mirror image adopts the texture state, and the rearview mirror effect is realized by replacing the texture dynamically in real time, which specifically includes the following steps:

[0052] 1) Obtain the scene coordinates when the vehicle is driving, use the vehicle dynamics model to obtain the coordinates of the vehicle in the three-dimensional coordinate system x, y, z, and the three-dimensional angles α, β, γ of the vehicle's running posture, and set the simulation step size T; The basic movement of the vehicle can be divided into straight line and turning: the controlled vehicle can drive under any working conditions in the program, including forward straight driving, steering driving, braking and reversing; it is realized by est...

Abstract

The invention discloses a rearview mirror simulation method for a vehicle driving simulation system. The method comprises the following steps: firstly, obtaining specific position and coordinate of a vehicle according to vehicle motion, capturing a rearview mirror scene by a rearview mirror camera to obtain a rearview mirror top point coordinate required to be drawn, connecting top points in sequence to form a rearview mirror surface which is rearview mirror texture, and finally pasting the rearview mirror texture onto a rearview mirror model; during driving simulation, pre-binding initial texture, replacing old texture with new texture in real time through a created pointer function, and finally finishing simulation of a whole rearview mirror. According to the method, the rearview mirror effect is creatively displayed on a vehicle model in a three-dimension manner, so that the trouble caused by occupation of main view angle can be avoided, the refresh rate of the system can be reduced, and the vividness of whole driving simulation can be improved; the method has good commercial values.

Description

technical field [0001] The invention relates to a rearview mirror simulation method for a vehicle simulation driving system, in particular to a rearview mirror effect that can be artificially controlled and dynamically simulated on a display (or display screen) according to driving manipulation requirements. Background technique [0002] At present, in the vehicle simulation driving system, there are few studies on rearview mirror simulation. At present, only through multi-window display technology, a rearview mirror channel can be added to the driver's perspective. Although this can achieve rearview mirror simulation, but Occupy the front viewing angle, and if the window is too small, the rearview mirror image will not be clear; the window is too large, blocking the front view. [0003] When actually driving, the rearview mirror is a key safety component for the driver. Since the entire simulation system is a simulated driving, the driver must have a strong sense of three-...
