Embodiment 1
[0049] An embodiment of the present invention provides a night vehicle driving assistance device, such as figure 1 As shown, the device includes: a night vision module, a vehicle speed acquisition module, a braking distance calculation module, a warning area judgment module, a warning area adjustment module and a warning light control module.
[0050] The vehicle speed obtaining module is used to obtain vehicle speed information, and the braking distance calculation module is used to calculate the braking distance according to the vehicle speed information and the vehicle environment.
[0051] The warning area adjustment module is used to adjust the warning area according to the braking distance and the position of pedestrians.
[0052] The night vision module is used for the night vision module to obtain pedestrian position information in the night environment.
[0053] The warning area judging module is used for judging whether the pedestrian is in the warning area or is ap...
Embodiment 2
[0072] A feasible embodiment of the present invention provides a nighttime vehicle driving assistance method. Specifically, such as Figure 5 As shown, the night vehicle driving assistance method includes:
[0073] S1. Obtain night vision images, obtain road information and pedestrian location information;
[0074] S2. According to the road ahead information and pedestrian location information, determine whether the pedestrian is in the warning area or is approaching the warning area;
[0075]S3. When the pedestrian is in the warning area or is approaching the warning area, turn on the warning light according to the position information of the pedestrian.
[0076] Further, when obtaining road information and pedestrian position information, obtain the current vehicle speed, and calculate the braking distance according to the vehicle speed and vehicle environment;
[0077] Adjust the warning area according to the braking distance and pedestrian position.
[0078] Further, a...
Embodiment 3
[0094] In another possible embodiment of the present invention, a vehicle is provided. The vehicle has a nighttime vehicle driving assistance device.
[0095] After the device detects the position of the pedestrian through the night vision module, the warning light can be turned on through the warning light control module, and the light can be irradiated to the foot of the pedestrian. By illuminating pedestrians with warning lights, the driver does not have to shift his sight to the instrument display when driving at night or in foggy days. The vehicle can illuminate pedestrians with a separate beam, making it easier for drivers to notice pedestrians and reduce nighttime vehicles. Risk of collision with pedestrians.
