Description
Technical field
This utility model relates to technical field of automotive electronics, particularly relates to a kind of vehicle-mounted sunlight sensor.
Background technology
Development along with electronic technology, Hyundai Motor air conditioning system is by computer control, the air conditioning system that perfect automobile computer controls is possible not only to the temperature of air, humidity, cleannes, demeanour and direction in car are automatically adjusted, a good environment by bus is provided to passenger, ensure to make passenger all in a comfortable air ambient under different outside climatic and condition, and fault detect can also be carried out. But the air conditioning system that car-mounted computer automatically controls is when work, and automotive interior temperature is affected by many factors, as: the setting of air conditioning system self-temperature and air output, the degree of strength at outside sunshine and outside sunshine-duration etc.
When the solar irradiation outside car is mapped in car, raising or reducing of vehicle interior temperature needs certain buffer time, and in during this period of time, air conditioning system still keeps original state, and now passenger can not feel well. In order to enable actual temperature in car to reach optimization according to user's setting value, need multiple sensor to detect the value of each ambient parameter, thus environmental data passes to air-conditioner control system, air-conditioner control system, according to the data obtained, adjusts duty automatically.
The effect of vehicle-mounted sunlight sensor detects the irradiation intensity of the outer sun of car exactly, this parameter is an initial conditions of the algorithm logic as automatic air-conditioning system, when automobile travels facing to the sun, vehicle-mounted sunlight sensor can detect that intensity of illumination is significantly high, and at this time air-conditioner controller can automatically turn down leaving air temp and blower speed.
Existing vehicle-mounted sunlight sensor has the disadvantage that
One be the euphotic cover cross section of vehicle-mounted sunlight sensor is circular arc, as shown in Figure 1 (wherein arrow represents the light of low angle of incidence), on the one hand owing to the distance of the passed euphotic cover of the sunlight of low incidence is not wait, causing that low-angle light is too much by this absorbed of printing opacity, the sensitivity of light is declined by vehicle-mounted sunlight sensor;On the other hand, due to the refraction of light, low-angle light cannot arrive light sensitive diode 2, reduces the sensitivity to light of the vehicle-mounted sunlight sensor.
Two is period at noon, it is arranged near automobile rearview mirror owing to vehicle-mounted sunlight sensor is usually, and people is seated within a vehicle, the sunlight at noon can be blocked by the ceiling of car greatly, people is seated within a vehicle not awfully hot, and vehicle-mounted sunlight sensor does not block, it is easy to cause erroneous judgement, start the air-conditioning in car.
Three is be provided with adjacent main driving light sensitive diode and copilot light sensitive diode on vehicle-mounted sunlight sensor, when sunlight is from the side window incidence of main driving, simply main driving is hotter, the sunlight of copilot can be blocked a part, but it is unscreened between main driving light sensitive diode and copilot light sensitive diode, main driving air-conditioning and copilot air-conditioning can be started after they perception sunlight, cause energy waste.
Utility model content
The technical problems to be solved in the utility model is: in order to solve above-mentioned 3 deficiencies, and this utility model provides a kind of vehicle-mounted sunlight sensor, it is possible to increase the light sensitivity of vehicle-mounted sunlight sensor, it is to avoid erroneous judgement, and energy efficient.
This utility model solves its technical problem and be the technical scheme is that a kind of vehicle-mounted sunlight sensor, including wiring board, light sensitive diode in the circuit board and euphotic cover are installed, described euphotic cover is located at the top of light sensitive diode, the outer surface of described euphotic cover is arc surface A, inner surface is arc surface B, and the center of circle of the circle at the center of circle of the circle at arc surface A place and arc surface B place is all in the lower section of euphotic cover. Owing to the inner surface of euphotic cover is also designed to arc-shaped, namely a part is cut out, make euphotic cover thickness generally uniform, the incident illumination (especially low-angle incident illumination) of same angle, of substantially equal through the distance of euphotic cover, the loss of the light arriving light sensitive diode is also just of substantially equal; Low-angle incident illumination can also arrive light sensitive diode simultaneously, improves the light sensitivity of vehicle-mounted sunlight sensor.
Erroneous judgement in order to avoid period at noon vehicle-mounted sunlight sensor, the inner surface of described euphotic cover is provided with light diffusion bar, in order to reflect incident ray, described light diffusion bar is positioned at the surface of light sensitive diode, can be a plurality of arranged in parallel, a plurality of arranged in parallel after cross section substantially in wavy. When noon section, the sunlight of direct projection can weaken after being spread bar refraction by light, it is to avoid in car, air-conditioning is opened too early, reduces energy consumption.
Of the prior art thirdly not enough in order to solve, described light sensitive diode is two, and a light sensitive diode controls the air-conditioning of main driving, and another controls the air-conditioning of copilot, be provided with between two light sensitive diodes one piece lighttight every tabula rasa. When sunlight is from the side window incidence of main driving, owing to having blocked the light of main driving side every tabula rasa, it is possible to only start main driving air-conditioning, the air-conditioning of copilot will not be started, it is to avoid energy waste, reduce energy consumption simultaneously.
The beneficial effects of the utility model are, vehicle-mounted sunlight sensor of the present utility model:
One, owing to the inner surface of euphotic cover is also designed to arc-shaped, namely a part is cut out, make euphotic cover thickness generally uniform, the incident illumination (especially low-angle incident illumination) of same angle, of substantially equal through the distance of euphotic cover, the loss of the light arriving light sensitive diode is also just of substantially equal, and low-angle incident illumination can also arrive light sensitive diode simultaneously, improves the light sensitivity of vehicle-mounted sunlight sensor;
Two, the light diffusion bar that the inner surface of euphotic cover is arranged, when noon section, the sunlight of direct projection can weaken after being spread bar refraction by light, it is to avoid in car, air-conditioning is opened too early, reduces energy consumption;
Three, between two light sensitive diodes arrange every tabula rasa, when sunlight is from the side window incidence of main driving, owing to having blocked the light of main driving side every tabula rasa, can only start main driving air-conditioning, the air-conditioning of copilot will not be started, it is to avoid energy waste simultaneously, reduce energy consumption.
