Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The invention provides a control method of an automobile turning lighting system, which solves the problem that the response of a side lighting unit has hysteresis aiming at the conditions that turning on a turn signal lamp is late, a driver turns on a road with few people or poor lighting at night, and the like. Wherein, two side lighting units can be respectively arranged at two sides of the vehicle body, and also can be arranged at the outer sides of the left and right rearview mirrors, the control method comprises the following steps:
s1: the road surface information is obtained in real time through a GPS positioning device, a first camera and an electronic map, wherein the first camera is positioned on the back of a central rearview mirror in the vehicle.
S2: it is determined whether the front is a curve, a crossroad, or a t-junction based on the road surface information, and if yes, the process proceeds to step S3, and if not, the process proceeds to step S1.
S3: and acquiring the outside illumination intensity through the photosensitive sensor and judging whether the illumination intensity is lower than a first threshold value, if so, entering step S4, otherwise, entering step S1. If the obtained external illumination intensity is higher than the first threshold value, the obtained external illumination intensity indicates that the external light is sufficient for the vehicle, and the vehicle can normally run without starting the side lighting unit; if the external illumination intensity is lower than the first threshold value, the external light is insufficient, and the side lighting unit needs to be started to ensure the driving safety.
S4: if the turn signal is on, the process goes to step S7 if yes, and if not, the process goes to step S5;
s5: and monitoring whether the head of the driver rotates left and right through the second camera, if so, entering S6, and if not, entering S1. The second camera can be installed at the A column, the angle of the second camera can be adjusted according to the head rotation angle of the driver, so that if the head of the driver turns to the rearview mirror, the second camera captures the front face of the driver, the front face image of the driver can be successfully matched with the front face image of the driver collected in advance, and the fact that the driver probably has the turning intention is indicated.
S6: whether the vehicle is turning or not is judged according to the road surface information and the lane where the vehicle is located, if yes, the process goes to S7, and if not, the process goes to S1. The first camera can detect the lane where the vehicle is located.
S7: and turning on the lighting unit on the corresponding side according to the turning-on direction of the steering lamp or turning on the steering lamp and the side lighting unit on the corresponding side according to the head rotating direction.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
