Description

Device and vehicle for assisting driving

technical field

The utility model relates to the field of automotive electronics, in particular to a device for assisting driving and a vehicle.

Background technique

When driving a car at night on the road, it is often encountered that the oncoming car has turned on the high beam. At this time, the driver can not see the road clearly because of the glare of the high beam. The general lighting conditions of the roads in the city are relatively good. Therefore, it is not recommended to turn on the high beam when driving a vehicle in the city. If the high beam angle is too high, it is easy to dazzle the eyes of oncoming vehicles and pedestrians around, affecting their sight and causing traffic hazards.

In order to avoid being dazzled by the high beams of oncoming vehicles, usually drivers can reduce the impact of high beams on vision by wearing night vision goggles or using light barriers. Yellow night vision goggles and yellow light barriers can filter out the high-energy, short-wavelength ultraviolet light and blue light emitted by the car's high beams, allowing the human eye to see softer lights, thereby reducing safety risks.

However, driving glasses are not suitable for people who usually wear glasses, and if worn for a long time, it is easy to cause eye fatigue. The sunshield is generally placed on the front windshield, and this light-reducing object will block part of the driver's vision in front of him, forming a blind spot in the vision. And the light barrier will shake with the bumps of the car body. If the time is long, the driver will have adverse reactions such as headache, dizziness and nausea.

The photosensitive module 11 is used for sensing the light intensity of the light irradiated from the front of the vehicle to the front windshield of the vehicle. The filter module 12 is connected with the photosensitive module 11, and is used for filtering light within a predetermined wavelength range in the light when the light intensity sensed by the photosensitive module 11 is greater than a predetermined light intensity threshold.

Wherein, when the light intensity sensed by the photosensitive module 11 is greater than a predetermined light intensity threshold, it can be considered that the light of the high beam headlight of an oncoming vehicle is irradiated on the front windshield of the vehicle. The predetermined light intensity threshold can be obtained empirically or experimentally. For example, the predetermined light intensity threshold may be set as 5000cd (candela, candela).

The filter module 12 may be a device capable of filtering out high-energy, short-wavelength violet light and blue light. For example, the predetermined wavelength range may be 380nm˜500nm. After the light within the predetermined wavelength range is filtered out of the light irradiated on the front windshield, the driver in the car will see that the original dazzling light from the high beam of the oncoming car will turn into a soft yellow color.

Wherein, the user can generate a filter indication signal by triggering the filter switch 1221 . For example, the filter switch 1221 can be set on the panel of the device, and can include an "on" or "off" button, and the user presses the "on" button, which triggers the generation of an electrical signal connected to the filter control circuit 122 . The connection of the filter control circuit 122 enables the filter control circuit 122 to control the filter film 121 to perform filtering. The user presses the “OFF” button, which triggers the generation of a signal to turn off the filter control circuit 122 .
