Embodiment Construction

[0035] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The existing high and low beam switching devices generally only collect ambient light intensity through a single sensor, and compare the collected ambient light intensity with the pre-stored night environment standard value to switch between high and low beam lights. The night environment standard value here is only It is an approximate value, and cannot be calibrated according to the specific night environment (for example, snowy night, dark night, moonlit night, night with street lights, etc.), so the high and low beam control technology is not accurate enough, a...

Abstract

A control device for high-beam and low-beam lights comprises a first sensor, a second sensor and a control module. The first sensor is used for acquiring ambient light intensity. The second sensor is used for acquiring vehicular front light intensity. The control module is used for acquiring the ambient light intensity acquired by the first sensor and the vehicular front light intensity acquired by the second sensor, determining the current specific night environment according to the ambient light intensity, and switching the high-beam and low-beam lights according to the current specific night environment and the vehicular front light intensity. Therefore, when vehicles meet with one another, the high-beam and low-beam lights are controlled to switch by determining the current specific night environment according to the data acquired by the first sensor and using the data acquired by the second sensor. The control device and the control method can be used to switch the high-beam and low-beam lights more accurately.

Description

technical field [0001] The invention belongs to the field of vehicle high and low beam control, and in particular relates to a vehicle high and low beam control device and a control method thereof. Background technique [0002] The traditional way to turn off the far and near lights of vehicles is generally to manually turn on and switch the high beam and low beam lights, but when meeting or turning, due to the nervousness of the driver, misoperation may occur, which may cause traffic violations in the slightest, and lead to traffic accidents in severe cases. traffic accident. [0003] At present, although there is also an automatic control technology for switching between high and low beams according to the ambient illuminance, this technology generally only collects the ambient illuminance through a single sensor, and compares the collected ambient illuminance with the pre-stored night environment standard value. High and low beam switching, but the night environment stan...
