Description
Technical field
This utility model belongs to auto electroincs technical field, is specifically related to a kind of automobile low beam light automatic switching control equipment at expressway ramp mouth.
Background technology
In recent years, flourish along with China's economy, sale of automobile total amount has reached the whole world first, and total vehicle is substantially increased the most accordingly.But, while becoming world car big country with China, vehicle accident casualties number the most continuous ten years is high to rank first in the world, and old course road traffic safety problem should cause enough attention.Owing to speed is higher, speed changes greatly, following distance is short at expressway ramp mouth, when particularly travelling under night illumination condition unfavorable condition, easily cause vehicle accident.Night, automobile would generally open high beam to increase driver's seat when highway driving; and when sailing at expressway ramp mouth; if in time high beam not being switched to dipped headlights; automobile front light will be transferred to road edge guard rail position by Expressway Road central authorities; driver cannot effectively observe road ahead situation; in addition to roll super expressway speed away from the highest for automobile, and road safety accident the most easily occurs.
At present, existing far and near light automatic regulating device is only limitted to the situation of two car intersections mostly, this eventful spots of expressway ramp and Multiple trauma are rarely had and relates to, and be used mostly the photoactive material that performance is more unstable, affected by driving circumstances around automobile bigger.Automobile is to run at high speed on a highway, when walking at ring road mouth, if not regulating the high beam of automobile to dipped headlights in time, easily causing road safety accident, thus causing personal injury and property loss.
Summary of the invention
In order to solve the problems of the prior art, the utility model proposes one can night running car to being automatically adjusted automobile front time at expressway ramp mouth to dipped headlights, improve the automobile low beam light automatic switching control equipment at expressway ramp mouth of drive safety.
In order to realize object above, the technical scheme that this utility model is used is: include the vehicle speed sensor for detecting automobile speed, for detecting the gyroscope of running car yaw angle and for determining the GPS navigator of vehicle running route, described vehicle speed sensor, gyroscope and GPS navigator are connected to the input of electronic control unit ECU, and the outfan of electronic control unit ECU connects high beam and the dipped headlights of automobile.
The outfan of described electronic control unit ECU is connected to the dipped headlights of automobile by relay.
Described electronic control unit ECU connects vehicle power.
Described electronic control unit ECU uses STM32F407ZGT6 processor.
Described vehicle speed sensor is arranged on the output shaft of automotive transmission.
Described vehicle speed sensor uses rich prestige BW-1017.
Described gyroscope is arranged in GPS navigator.
Described gyroscope uses A3G4250D gyroscope.
Described GPS navigator uses Newman K60.
Compared with prior art, this utility model is by arranging vehicle speed sensor to detect automobile speed, automobile-used gyroscope is set to detect the traveling yaw angle of automobile, GPS navigator is set to determine the travel route of automobile, electronic control unit ECU gathers and processes signal and the data of vehicle speed sensor, gyroscope and GPS navigator, thus judge that automobile has walked at expressway ramp mouth, and switch automobile front to dipped headlights, it is achieved the automatic switchover of motorway ring road dipped headlights.This utility model simple in construction, to dipped headlights, lighting condition can be improved, improve driver's seat by automatic switching automatic headlight at this Accident Area of garage to expressway ramp, thus reduce vehicle accident incidence rate, and alleviate the driver workload of driver.
Further, the electronic control unit ECU switching by Control dipped headlights, control reliable and stable.

Detailed description of the invention
Below in conjunction with the utility model is further explained the explanation of specific embodiment and Figure of description.
See Fig. 1, this utility model includes the vehicle speed sensor 1 for detecting automobile speed, vehicle speed sensor 1 uses rich prestige BW-1017, for detecting the gyroscope 2 of running car yaw angle, gyroscope 2 uses STMicroelectronics (STMicw Electronics) A3G4250D, for determining the GPS navigator 3 of vehicle running route, GPS navigator (3) uses Newman K60, and for processing the electronic control unit ECU4 of the data signal of vehicle speed sensor 1, gyroscope 2 and GPS navigator 3；Vehicle speed sensor 1, gyroscope 2 are connected with the signal input part of electronic control unit ECU4 with the signal output part of GPS navigator 3；The outfan of electronic control unit ECU4 is connected through the input of relay 5 with dipped headlights 6, and electronic control unit ECU4 connects vehicle power, and electronic control unit ECU4 uses STM32F407ZGT6 processor.Vehicle speed sensor 1 is arranged on the output shaft of automotive transmission, and gyroscope 2 is arranged in GPS navigator 3.
See Fig. 2, specific works flow process of the present utility model is as follows: night, automobile normal running was on highway, when walking at expressway ramp mouth, car deceleration travels, vehicle speed sensor 1 goes out automobile speed by the change-detection of transmission output speed and reduces, gyroscope 2 detects that running car yaw angle changes, in addition, GPS navigator 3 detects that automobile will sail expressway ramp in real time, electronic control unit ECU4 obtains vehicle speed sensor 1, gyroscope 2 and the signal of GPS navigator 3 three and data, make according to current automobile front light status simultaneously and judging accordingly: if currently as dipped headlights, do not operate, keep current dipped headlights state；If being currently high beam, then electronic control unit ECU4 outputs signal to relay 5, and trigger relay 5 cuts out high beam and opens dipped headlights 6, thus realizes when automobile enters expressway ramp automatic switching automatic headlight to dipped headlights.After automobile rolls expressway ramp away from, owing to entering common low speed road, road conditions tend to complicated, therefore this utility model will no longer operate, if need to be decided in its sole discretion dipped headlights switchback high beam according to current driving situation by driver.Electronic control unit ECU4 is write certain procedures, when speed changing value, yaw angle, gps signal reach certain condition, electronic control unit ECU4 output signal trigger relay.Arranging speed change predetermined value when automobile sails expressway ramp in program is Δ V0, yaw angle predetermined value θ 0, when automobile at night sails expressway ramp into, automobile driving speed and yaw angle will change, exceed set predetermined value once these changing values, i.e. meet Δ V ＞ Δ V0, θ ＞ θ0, and electronic control unit ECU receives GPS and the signal that garage sends to expressway ramp detected, then electronic control unit ECU makes according to current automobile front state and judging accordingly: if currently as dipped headlights, not operating；If being currently high beam, then electronic control unit ECU outputs signal to relay and is allowed to close high beam and opens dipped headlights.
This utility model is by the vehicle speed sensor of automotive internal, gyroscope, the status data of GPS navigator acquisition automobile and signal, and judged whether automobile sails expressway ramp into by electronic control unit ECU, and then automatic switching automatic headlight is to dipped headlights, it is not required to additionally add photoactive material, improve the lighting condition at expressway ramp mouth, improve driver's seat, reduce vehicle accident incidence rate, and alleviate the driver workload of driver.
