Abstract
The utility model discloses a rear-end collision prevention device for vehicles, relating to a rear-end collision prevention device for motor vehicles. The rear-end collision prevention device comprises a power supply, a part outside a vehicle and a part inside a vehicle, the part inside the vehicle comprises a CPU connected with the power supply, a system controller, a keyboard, a display and an alarm device, the keyboard is connected with one input end of the CPU, the system controller is connected with the CPU, and the display and the alarm device are respectively connected with the output end of the system controller; and the part outside the vehicle comprises a far infrared sensor and an ultrasonic ranging sensor which are respectively connected with the CPU of the part inside the vehicle. The utility model fully utilizes a modern high and new technology and a high integrated device and has simple structure and high cost performance. When driving at freeway and under a road condition with lower visibility, drivers can be prompted to learn whether vehicles exist within a safe distance in front.
Description
Technical field
The utility model relates to the device that a kind of preventing motor-vehicle knocks into the back.
Background technology
The existing automobile-used anti-device that knocks into the back adopts the mode of radar and ultrasonic ranging mostly, and not only radar mode cost height, and debugging is installed all inconvenient.And the range finding of ultrasound wave mode is short, just can not effectively use in the lower road conditions of highway and visibility.Therefore in a single day inclement weather occurs, particularly along with Freeway Development, the rear-end collision that occurs on highway is just more.
The utility model content
In order to overcome the deficiency of the existing automobile-used anti-device that knocks into the back, the utility model provides the automobile-used anti-device that knocks into the back of a kind of pair of detecting pattern, the not only powerful superior performance of this device, and very high cost performance is arranged.
The utility model comprises part in power supply, the outer part of car and the car, part is by the CPU processor, system controller, keyboard, display, the alarm that are connected with power supply in the described car, described keyboard is connected an input end of CPU processor, system controller is connected with the CPU processor, and described display and alarm are connected to the output terminal of system controller; The outer part of described car is made up of far-infrared sensor and ultrasonic ranging sensor, and described far-infrared sensor is connected with the CPU processor of part in the car respectively with the ultrasonic ranging sensor.
Because of the distance that small-sized ultrasonic ranging system is measured limited, and the far-infrared sensor distance accuracy is relatively poor, therefore this device has adopted double mode detection, phase one: adopt the sensitivity infrared sensor that can become far away that the place ahead vehicle far away is surveyed subordinate phase: to adopt ultrasonic ranging system that front vehicles is carried out range observation.The sensitivity of far-infrared sensor remains on the highest during operate as normal, when detecting the place ahead vehicle far infrared information arranged, far-infrared sensor sensitivity will reduce with certain speed, as also receive front vehicles far infrared information through a period of time, this device will send early warning information, starts ultrasonic ranging system simultaneously, and front vehicles is carried out precision ranging, as record distance and arrive safe distance the time, this device will send the acousto-optic warning.
After if the sensitivity of far-infrared sensor reduces, when can not receive front vehicles far infrared information, the sensitivity of far-infrared sensor keeps, when in the regular hour, not receiving front vehicles far infrared information once more, the sensitivity of far-infrared sensor will increase big with certain speed, up to receiving front vehicles far infrared information.
The utility model is made of Che Nei and outer two parts of car, the front end that the far-infrared sensor of the outer part of car and ultrasonic sensor can be installed in shell, and the outer part of part and car is electrically connected by cable in the car.
The utility model is closely found range and these two kinds of different detection modes of far infrared deterctor long-range detection vehicle by ultrasound wave, can survey the place ahead vehicle far away, also can carry out precision ranging to nearer vehicle, therefore, the utility model can also can use in urban road in use on the highway.The utility model fully adopts the device of modern high-new skill and high integration, cost performance height simple in structure.When in the lower road conditions of highway and visibility, travelling, can remind the driver in the safe distance whether vehicle to be arranged forwardly.
Description of drawings
Fig. 1 is a kind of schematic block circuit diagram of the present utility model.
Among the figure, the 1. outer part of car, 2. part in the car, 3. far-infrared sensor, 4. ultrasonic ranging sensor, 5. overall treatment device CPU, 6. system's control, 7. keyboard, 8. power supply, 9. display, 10. sound and light alarm.
Embodiment
Shown in Figure 1, the utility model comprises power supply 8, the outer part 1 of car and Che Nei part 2.
Part 2 is by the CPU processor 5 that is connected with power supply 8, system controller 6, keyboard 7, display 9, alarm 10 in the car.Keyboard 7 is connected an input end of CPU processor 5, and system controller 6 is connected with CPU processor 5, and display 9 and alarm 10 are connected to the output terminal of system controller 6.
The outer part 1 of car is made up of far-infrared sensor 3 and ultrasonic ranging sensor 4, and far-infrared sensor 3 is connected with the CPU processor 5 of part 2 in the car respectively with ultrasonic ranging sensor 4.
The sensitivity of far-infrared sensor 3 remains on the highest during operate as normal, when far-infrared sensor 3 detects the place ahead the far infrared information of vehicle is arranged, this information is imported CPU processor 5 into, CPU processor 5 sends instruction, reduce far-infrared sensor 3 sensitivity, far-infrared sensor 3 continues to receive front vehicles far infrared information, and CPU processor 5 starts ultrasonic ranging sensor 4; After the sensitivity of far-infrared sensor 3 reduces, when can not receive front vehicles far infrared information, the sensitivity that 5 controls of CPU processor keep far-infrared sensor 3, when in the regular hour, not receiving front vehicles far infrared information once more, the sensitivity that 5 controls of CPU processor strengthen far infrared deterctor 3 is up to receiving front vehicles far infrared information.
