The invention relates to a large van and semitrailer steering meniscus display prompter. The prompter is composed of a camera, a display, a steering gear box steering sensor, a vehicle speed sensor and a signal processor; a vehicle driving exterior scene image shot by the camera is transmitted through the signal processor so as to be displayed by the display; left and right steering signals generated by the steering gear box steering sensor are analyzed and calculated through the signal processor, so that left or right meniscus graphic signals which correspond to a steering angle and a steering direction and are matched with an exterior scene are superposed and displayed on the display; and the signal processor can generate complete meniscus graphic signals. The number and installation positions of cameras are determined and generated according to vehicle type characteristics, and the optimal scheme of the number and installation positions of the cameras is obtained through an experiment; and the shape of a meniscus area graph is determined and generated on the basis of a vehicle type (a semitrailer or not), the number of axles, and the relation between the turning angle and turning radius difference of an axle distance through an experiment and the algorithm of the signal processor.

    “大型客货车、半挂车转向弯月区显示提示器”由摄像头、显示器、方向机转向传感器、车速传感器和信号处理器几部分组成。摄像头拍摄的汽车行车外景图像,通过信号处理器到显示器显示,方向机转向传感器产生的左右转向信号,通过信号处理器分析计算,产生与转向角度、方向对应并和外景匹配的左或右弯月区图形信号叠加显示于显示器上,信号处理器可以产生完整的弯月区图形信号。摄像头的数量和安装位置根据车辆类型特点并通过实验取最佳方案,而弯月区图形的形状,通过对车辆类型(是否半挂车)、轴数、轴距的转弯角度与转弯半径差的关系,通过实验,进一步结合信号处理器的算法来确定和产生。
