Embodiment Construction

[0147] Embodiment of the invention

[0148] (1) Example of avoiding rear-end collision

[0149] Car A (rear car): Huanghe BK650 (large passenger car), L A =10.50m, V A =90km / h;

[0150] B car (front car): Dongfeng EQ144 (large truck), L B =8.135m, V B =? to be found;

[0151] The road base: asphalt road.

[0152] A car driver operating procedures:

[0153] 1. Press the main power button [25], the main power indicator light [1] is on, and the display screen [22] shows the following:

[0154]

[0155] 2. Press the blinker button [26], and the quartz blinker [10] starts to blink: "1, 2, 3...8, 9, 0", repeating itself.

[0156] 3. The reflective prism drive motor power supply switch [69] on the gate makes the drive motor system in a standby state.

[0157] 4. Point the speed knob [27] to the actual driving speed "90km / h", and a set of numbers will be displayed in "Table A" on the display screen as follows:

[0158] speed

S' A、B m

Abstract

A collision preventing device for car running on expressway is composed of a special laser distance finder with multiple display functions, electrically controlled two sets of elevation and depresion reflecting prisms and an interphone using private frequency band. The time and distance between two cars can be displayed in real time mode.

Description

technical field [0001] The invention belongs to the technical field of transportation and is mainly applied to automobiles running on expressways. Background technique [0002] At present, the expressways of countries in the world are developing rapidly, but there are also more and more traffic accidents in which rear-end collisions and overtaking collisions occur. The main cause of the collision accident is that between the front and rear two cars and when overtaking, the distance between the overtaking car and the oncoming car is too small. Up to now, no one has proposed: 1) when the car is driving on different roadbeds at different speeds, how much the minimum distance between it and the car in front should be kept, so as to avoid rear-end collision; 2) when "overtaking starts" , when the overtaking vehicle and the oncoming vehicle are advancing at different speeds per hour, how much minimum distance should be kept between them, so as to avoid overtaking collision. So f...
