Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is further described: in radar 7 ( Figure 4 Middle) BG2 is a microwave oscillating tube, the base has a microwave transmission belt, the collector of BG2 is connected to the amplifier IC1, the amplification is controlled by the "safety distance" ABCD and coupled to the positive pole of the antenna and diode D through the microwave transmission belt, and transmits pulses to the target , only obstacles within a safe distance can reflect back the signal, and the same antenna picks up and mixes with the original signal sent by D, the difference frequency appears at the base of BG1, and the amplified output is sent to the analog switch 9 (IC5CD4006), whether The transmission to the subsequent stage must be determined by the comparator 8. According to the Doppler effect, the frequency increases when an obstacle approaches. Only signals bouncing off obstacles with a higher frequency than the original transm...

Abstract

The invention is an intelligent safe driving system. It is made up of forward vision radar, side-glance radar and antenna, it can detect if there has obstacle in í‹safe rangeíŒ, the distance is decided by the speed, weight, road condition and car lengthwise incline, the received reflected wave signal is identified by the comparator. The obstacle signal is reformed with filter, and it is amplified to execution circuit, actualizes deceleration or brake, in order to upgrades the reliability of signal transmission, the microchip processes the signal received by radar synchronously, the microchip also reads the speed, weight, weather conditions, and other parameters table or works out the í‹safe distanceíŒ.

Description

technical field [0001] The invention relates to the field of transportation, the identification of obstacles during the driving of motor vehicles, and the intelligent control of vehicle speed to ensure that no collisions, rear-end collisions, extrusions, or falling off cliffs occur when the vehicle is running, and the system is not affected by the skills and status of the driver , in line with driving habits and regulations. Background technique [0002] At present, all motor vehicles do not have active collision avoidance systems, and only some passive protection measures, such as seat belts, anti-collision airbags, and helmets, cannot fundamentally solve the occurrence of traffic accidents. [0003] According to reports, some countries are researching auto navigation, computer navigation, and intelligent vehicle highway system (IVHS). Toyota's AXV-III uses laser positioning to prevent rear-end collisions. The U.S. driving radar system detects ...
