Information display method and system, controller and vehicle

The invention discloses an information display method and system, a controller and a vehicle, and belongs to the technical field of electronics. The method is used for a controller in a vehicle, the vehicle further comprises a camera and a displayer, and the method comprises the steps that the camera is controlled to collect images outside the vehicle; when the target obstacle exists in the image, controlling a display to display the image at a target refresh rate; and when the target obstacle does not exist in the image, controlling the display to display the image at an auxiliary refresh rate, the target refresh rate being greater than the auxiliary refresh rate. The problem that the image display flexibility of the electronic rearview mirror is low is solved. The method and the device are used for image display. 本申请公开了一种信息显示方法及系统、控制器、车辆，属于电子技术领域。该方法用于车辆中的控制器，车辆还包括：摄像头和显示器，该方法包括：控制摄像头采集车辆外的图像；在该图像中存在目标障碍物时，控制显示器以目标刷新率显示该图像；在该图像中不存在目标障碍物时，控制显示器以辅助刷新率显示该图像，目标刷新率大于辅助刷新率。本申请解决了电子后视镜的图像显示灵活性较低的问题。本申请用于进行图像显示。
