In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1, the anti-glare method for the projection lamp in the vehicle provided by the invention comprises the following steps:
s1, arranging a sensing area at the periphery of a projection range of a projection lamp in a vehicle;
s2, monitoring whether an induction signal generated in the induction area is received;
and S3, if so, adjusting the operation parameters of the projection lamp in the vehicle.
From the above description, the beneficial effects of the present invention are:
according to the anti-glare method for the projection lamp in the vehicle, the induction area is arranged on the periphery of the projection range of the projection lamp in the vehicle, once the induction signal generated in the induction area is received, a person is indicated to approach the projection lamp in the vehicle, and once the approach of the person is detected, the operation parameters of the projection lamp in the vehicle are adjusted according to the preset parameters, such as turning off the projection lamp in the vehicle, reducing the brightness of the projection lamp in the vehicle or switching to a light source with low brightness, so that the effect of effectively avoiding strong light from damaging human eyes is achieved.
Further, step S3 specifically includes:
if so, turning off the projection lamp in the vehicle or reducing the brightness value of the projection lamp in the vehicle.
As can be seen from the above description, the projection lamp in the vehicle can avoid the damage to the human eyes through the above operation.
Further, step S2 specifically includes:
s21, identifying whether the sensing area contains a monitoring object or not;
s22, if yes, calculating a moving track of the monitored object in the sensing area, and analyzing whether the possibility of entering the projection range of the projection lamp in the vehicle exists within a preset time range or not according to the moving track;
and S23, if so, generating a sensing signal and transmitting the sensing signal.
It can be known from the above description that, through the above design, directional tracking of the monitored object entering the sensing area can be realized, whether the possibility of entering the projection range of the in-vehicle projection lamp exists or not is pre-judged through the moving track, and once the possibility of entering is judged, the operation parameters of the in-vehicle projection lamp are adjusted according to the preset parameters.
Further, step S22 specifically includes:
if so, calculating a relation curve between the position change of the monitoring object and the time, calculating the moving speed and the moving trend of the monitoring object according to the relation curve, and analyzing whether the possibility of entering the projection range of the projection lamp in the vehicle exists within a preset time range or not according to the moving speed and the moving trend.

In the actual design process, the driving response time of the projection lamp in the vehicle is usually much longer than the driving time of the sensing area, so that even if the driving instruction received by the sensing area is later than that of the projection lamp in the vehicle, the time of the sensing area entering the working state is earlier than that of the projection lamp in the vehicle or the two of the sensing area entering the working state simultaneously, and the better protection of human eyes is achieved.
Further, step S2 further includes:
if not, acquiring the current operation parameters of the projection lamp in the vehicle again after the preset time interval.
As can be seen from the above description, if it is determined that the in-vehicle projection lamp is in a non-operating state, such as shutdown or standby, polling is performed after a preset time interval, where the preset time interval may be set according to actual needs, and is usually set to 1-5s for one polling.
