The device comprises an angle sensor, a vehicle speed sensor, a single chip microcomputer and a speed reducer, wherein the angle sensor and the vehicle speed sensor are connected with the single chip microcomputer respectively; and the output end of the single chip microcomputer is connected with the speed reducer. The device is based on a single chip microcomputer technology and a sensor technology, and vehicle speed can be judged during the turning of the vehicle, and is limited and maintained within a safe range when the current speed of the vehicle is higher than safe vehicle speed, so that the driving safety is ensured. The device is simple in structure, easy to debug, high in reliability, low in cost and convenient to maintain, and turning accidents of the vehicle can be effectively reduced.
Description
Technical field
The utility model belongs to field of automobile safety, is specifically related to a kind of automobile turning automatic slow down device.
Background technology
Automobile because of action of centrifugal force, makes the left and right sides can produce inclination when running at high speed and when turning, and when the centnifugal force that brings when this inclination was excessive, the auto body angle of inclination is excessive will cause traffic accidents such as vehicle side turning sideslip.Therefore when crossing bend, galloping should slow down by the generation to avoid traffic accident, but reality is that many chaufeur understanding are less than the seriousness of problem, the blindly pursuit speed of not slowing down when crossing bend, so traffic accident such as rollover sideslip happens occasionally during automobile turning.
Summary of the invention
The purpose of this utility model is, a kind of automobile turning automatic slow down device is provided, and this device can be when automobile turning be limited to the speed of automobile in the safe range, guarantees driving safety.
In order to realize above-mentioned task, the utility model is solved by the following technical solutions:
A kind of automobile turning automatic slow down device comprises angular transducer, car speed sensor, micro controller system and retarder, and wherein, angular transducer is connected with micro controller system respectively with car speed sensor, the mouth connection reducer of micro controller system.
The utility model also has following other technologies characteristics:
Described angular transducer adopts the K4281309 sensor.
Described car speed sensor adopts the JK08/NS43NCT1 sensor.
Described micro controller system adopts the AT89C2051 micro controller system.
Described retarder adopts the DZSK-01 retarder.
The utility model can judge the speed of a motor vehicle when automobile turning based on singlechip technology and sensor technology, if the automobile present speed greater than the safe speed of a motor vehicle then the speed of a motor vehicle is limited, maintains within the safe range speed of a motor vehicle, guarantees driving safety.This apparatus structure is simple, be easy to debugging, reliability height, cost are low, is convenient to maintenance, can effectively reduce the generation of automobile turning accident.
Description of drawings
Fig. 1 is annexation scheme drawing of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
The specific embodiment
Fig. 1 is annexation scheme drawing of the present utility model, and this device comprises angular transducer, car speed sensor, micro controller system and retarder, and wherein, angular transducer is connected with micro controller system respectively with car speed sensor, the mouth connection reducer of micro controller system.In the utility model, the angular transducer that is installed on the vehicle steering adopts the K4281309 sensor, is used for obtaining the turn inside diameter angle information; Car speed sensor adopts the JK08/NS43NCT1 sensor, is used for obtaining current car speed information; Micro controller system adopts the AT89C2051 micro controller system, is used for data and handles; Retarder adopts the DZSK-01 retarder, is used for restricted speed.
Automobile in the process of moving, angular transducer and speed sensor constantly detect the current angle information of automobile and velocity information, and above-mentioned information is passed to micro controller system.Micro controller system judges to data and handles that micro controller system judges that then automobile is in turn condition at this moment when corner surpasses certain angle, and micro controller system can be known the turn radius R that works as vehicle in front according to angular transducer.Obtain after the R, micro controller system calculates the maximum speed Vmax that current turn radius R allows according to the vehicle movement dynamics formula, i.e. the safe speed of a motor vehicle, and computing formula is as follows:
Vmax=（ugR）
1/2
In the formula, u is the horizontal maximum friction coefficient of road, and g is acceleration due to gravity, and R is current turn radius, and wherein, the value of u and g is preset in the micro controller system.
Micro controller system compares the maximum speed Vmax that allows and the current car speed V that obtains by car speed sensor, if vehicle velocity V is less than safe speed of a motor vehicle Vmax, then automobile normal running; If this moment, vehicle velocity V was greater than the safe speed of a motor vehicle Vmax of automobile this moment, the work of Single-chip Controlling retarder reduces the speed of a motor vehicle, in the speed of a motor vehicle is reduced to safe vehicle speed range or automobile pass through bend; The driving abnormal activity that so just can avoid automobile to cause because of the driver personal factor in the negotiation of bends process improves traffic safety.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connection mode of electronic devices and components as can be known of the technical solution of the utility model.
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; above-mentioned specific embodiments only is schematic, guiding; rather than restrictive, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
