Described read out instrument all is positioned at meter panel of motor vehicle inside.
Described sound broadcasting device is made up of speech chip and loud speaker.
The utility model vehicle automatic early-warning speed governing safety device, by two laser range sensors separately with the distance between twice measurement of time gap t and the place ahead and front vehicle, be sent to micro controller system by electric signal, the impulse singla of photo-electric car speed sensor also is sent to micro controller system simultaneously, if the ratio that only detects relative distance and the relative speed of a motor vehicle between Ben Che and front truck is during less than 5s, the voice suggestion car retardation, and in read-out range of a signal and velocity information; If the ratio that only detects Ben Che and back workshop relative distance and the relative speed of a motor vehicle is during less than 5s, the acceleration of voice suggestion vehicle, and in read-out range of a signal and velocity information; If when detecting above-mentioned two kinds of early-warning conditions and all satisfying, voice suggestion vehicle lane change then.Chaufeur can in time be made the vehicle adjustment according to read-out and early warning information, avoids the generation of accident.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) this apparatus structure is simple, expense is low and be easy to installation.
(2) but this device have precision height, the sensitive continuous acquisition data of reflection and show, remind chaufeur to take reasonable measure timely and accurately.
(3) this device can effectively solve low visibility conditions such as night, rain, snow, mist, sand and dust and descend the car accident that causes because of the sighting distance deficiency.
(4) this device has remedied the deficiency of existing installation, not only can avoid knocking into the back, and can also prevent that vehicle from being knocked into the back, and has guaranteed the safety of road driving, can adapt to the vehicle of different model, and development prospect is wide.
