The device comprises a singlechip, a radar detection sensor used for collecting pedestrian signals in front of the vehicle and transmitting the signals to the singlechip, a loudspeaker used for taking charge of an audible alarm according to an output order of the singlechip, and an automatic braking module used for taking charge of reducing vehicle speed according to the output order of the singlechip, wherein the I/O input end of the singlechip is in electric connection with the output end of the radar detection sensor; the I/O output end of the singlechip is respectively in electric connection with the input ends of the loudspeaker and the automatic braking module. Through the adoption of the device, alarm reminding is performed on pedestrians and drivers under the condition of anticipating the danger, the vehicle speed is automatically reduced in a dangerous range, protection of the pedestrians is realized, and traffic accidents can be avoided.
Description
Technical field
The utility model belongs to traffic safety field, is specifically related to differentiate in a kind of Vehicle Driving Cycle pedestrian's avoiding device.
Background technology
Automotive safety is not only for the driver and crew in car, also will protect pedestrian's safety simultaneously, and therefore, vehicle collision guard technology also starts protection pedestrains safety to classify as its target of giving priority to.In recent years, the safe criticism of European new car association, in vehicle crash test, not only checks passenger's safety guard-safeguard degree, also checks the safety guard-safeguard degree of vehicle to pedestrian by dividing four stars.For effective protection pedestrian's safety, relevant laws and regulations, also need to improve the safety performance of automobile except specifying and implementing, in vehicle passive safety technology relatively ripe today, active safety shows out unique importance.And the just development of domestic automobile technology at present initiatively there is no Related product in protection field pedestrian.
Utility model content
The purpose of this utility model is to provide the avoiding device of differentiating pedestrian in a kind of Vehicle Driving Cycle; adopt this device in the time that situation is caused danger in anticipation, to carry out warning reminding to pedestrian and chaufeur; in risk range, automatically reduce the speed of a motor vehicle; realize the protection to pedestrian, the generation avoiding traffic accident.
In a kind of Vehicle Driving Cycle, differentiate pedestrian's avoiding device, it is characterized in that, comprise micro controller system, for the pedestrian signal in collection vehicle front and this signal is transferred to the radar detection sensor of micro controller system, for be responsible for the loud speaker of audible alarm according to the output command of micro controller system, for be responsible for reducing the self-actuating brake module of the speed of a motor vehicle according to the output command of micro controller system; The mouth of the I/O input end electrical connection radar detection sensor of described micro controller system, the I/O mouth of described micro controller system is electrically connected respectively the input end of loud speaker, self-actuating brake module.
Feature of the present utility model and further improvement are:
Also comprise for be responsible for controlling the lighting control module that far and near light switches mutually according to the output command of micro controller system the input end of the I/O mouth electrical connection lighting control module of described micro controller system.
Described micro controller system is Freescale MC9S12DG128 micro controller system.
Described radar detection sensor is multiple, is arranged on respectively top, the top of left and right headlight and the back side of back mirror of front part of vehicle air-inlet grille.
The utility model has adopted after technique scheme; survey and obtain pedestrian and vehicle standoff distance by radar detection sensor; this signal is transferred to micro controller system; through micro controller system to after the analyzing and processing of information; in the time that situation is caused danger in anticipation, pedestrian and chaufeur are carried out to warning reminding; in risk range, take automatically to reduce the speed of a motor vehicle etc. and hide measure, realize the protection to pedestrian, the generation avoiding traffic accident.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the hardware module block diagram of differentiating pedestrian's avoiding device in a kind of Vehicle Driving Cycle of the present utility model.
The specific embodiment
With reference to Fig. 1, for differentiating the hardware module block diagram of pedestrian's avoiding device in a kind of Vehicle Driving Cycle of the present utility model.This device comprises micro controller system, for the obstacle signal in collection vehicle front and this signal is transferred to the radar detection sensor of micro controller system, for be responsible for the loud speaker of audible alarm according to the output command of micro controller system, for be responsible for reducing the self-actuating brake module of the speed of a motor vehicle according to the output command of micro controller system, also comprise for be responsible for controlling the lighting control module that far and near light switches mutually according to the output command of micro controller system; Micro controller system adopts Freescale MC9S12DG128 micro controller system, the mouth of the I/O input end electrical connection radar detection sensor of micro controller system, and the I/O mouth of micro controller system is electrically connected respectively the input end of loud speaker, self-actuating brake module, lighting control module.Radar detection sensor is multiple, is arranged on respectively top, the top of left and right headlight and the back side of back mirror of front part of vehicle air-inlet grille, to reach, front obstacle is surveyed and pedestrian is accurately located without dead angle.Self-actuating brake module is an oil circuit in parallel on the oil circuit of the first electromagnetic valve, connects the 4th electromagnetic valve in oil circuit, adopts OR-NOT circuit control the second electromagnetic valve and the 3rd electromagnetic valve simultaneously.
The principle of work of this device is as follows, the shortest safety distance prestoring in micro controller system between vehicle and pedestrian, this device is by the pedestrian in radar detection sensor detection vehicle front, and the signal detecting is transferred to micro controller system, the Time Calculation that micro controller system returns by waveform obtains the standoff distance of pedestrian and vehicle, in the time that the standoff distance detecting being less than the shortest safety distance prestoring, loud speaker carries out audible alarm prompting to pedestrian and chaufeur, self-actuating brake module is carried out self-actuating brake to reduce the speed of a motor vehicle, when night travel, the far and near light of lighting control module control switches mutually, pedestrian is carried out to warning reminding, realize the protection to pedestrian by above measure, the generation avoiding traffic accident.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, rather than restrictive.Those of ordinary skill in the art, under the enlightenment of specification sheets, in the case of not departing from the scope that the utility model claim protects, can also make a variety of forms, and these all belong to the row of the utility model protection.
