In rainfall optical sensor, the system chart of rain sensor and light sensor respectively as depicted in figs. 1 and 2.RLS (Rain Light Sensor) be one for identifying the rainfall optical sensor of vapour quantity on Windshield and ambient light.According to the sensitivity obtaining steam information and client's setting, RLS judges whether that will send windscreen wiper to BCM (Body Control Module, controller) controls and corresponding master mode request.Meanwhile, RLS the situation of environmentally light can also judge whether the control request that will send light to BCM.
1. the optical principle of rainfall optical sensor
Rainfall optical sensor is the steam being sensed windscreen surface by optical principle, by judging that the amount of current steam determines whether to start windscreen wiper, if the steam of rainfall optical sensor surveyed area is wiped off by wiper blades in windscreen wiper swing process, rainfall optical sensor will adjust the state parameter of Windshield, and again calculates surveyed area.By such mode, windscreen wiper system and Windshield and rainfall optical sensor form a closed loop control system, as shown in Figure 3.
The optical model of rainfall optical sensor as shown in Figure 4.As can be seen from this figure, the light guiding surface of optical element is a parabola, if infrared transmitting tube, infrared receiving tube are all placed in paraboloidal focus like this, then the light incided on Windshield by optical element can think parallel rays.Rainfall optical sensor is that relative quantity is measured, and when glass surface drying, thinks that parallel light that infrared transmitting tube sends incides reflecting of being maximized after on Windshield, by infrared receiving tube is received after being converged by optical element.When Windshield outside face has raindrop, the light incided on Windshield is fallen by partial dispersion, and after reflection, the light of infrared receiving tube tails off, and rainfall is larger, and the light reflected is fewer.By with the comparing of receiving light power under Windshield drying regime, just can draw the number of the water yield on current Windshield, and then different rainy patterns can be judged.RLS, according to the rainfall size perceived, scrapes water request by LIN (Local Interconnect Network) bus to BCM transmission.BCM according to RLS send scrape water instruction control rain shaving electrical machine complete scrape accordingly hydrodynamic(al) do, scrape immediately once, low speed scrapes water continuously and high-speed and continuous scrapes water.
2. the optical principle of light sensor
The optical principle of light sensor as shown in Figure 5.A-quadrant is the detection range of top light line sensor, and B region is the surveyed area of vehicle front light light sensor, and the signal that these two light sensors receive is processed by RLS, controller.
Embodiment 1
In the embodiment of the present invention, by installing a rainfall optical sensor on the windshield, rainfall optical sensor realizes the perception of steam on glass by optical element.After RLS activates, by optical element, rainfall optical sensor identifies that waft rain, muddy water of light rain, moderate rain, heavy rain, beam wind splashes and to snow etc. different precipitation forms.Then rainfall optical sensor is according to the water yield of perception, sends corresponding function signal perform corresponding action to BCM, BCM according to this signal control rain shaving electrical machine by LIN bus.So just achieve automatic wiper function.
Rainfall optical sensor should be able to identify extraneous ambient light, and according to the situation of light, send corresponding passing light and position lamp on-off signal by LIN bus, request BCM lights or close passing light and position lamp.
