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.

Abstract

The invention relates to the field of intelligent driving and provides a nighttime vehicle driving assisting device and method, and a vehicle. The nighttime vehicle driving assisting device comprisesa night vision module, a vehicle speed obtaining module, a brake distance calculation module, a warning area judging module, a warning area adjusting module and a warning lamp control module. The nighttime vehicle driving assisting device can obtain pedestrian position information, forward road information, the vehicle speed and the brake distance. A warning area is adjusted according to the vehicle speed, the brake distance and the pedestrian position. The warning area judging module is used for obtaining the position information of a pedestrian and turning on a warning illumination lamp according to the pedestrian position information and the forward road information when the pedestrian is located in the warning area or approaches to the warning area. According to the nighttime vehicle driving assisting device, through the mode that the warning illumination lamp irradiate on the pedestrian, a driver pays attention to the pedestrian more easily, and the danger that the vehicle collides with the pedestrian in the nighttime is reduced.

Description

technical field [0001] The invention relates to the field of intelligent driving, in particular to a nighttime vehicle driving assistance device, method and vehicle. Background technique [0002] The car night vision device is a technology transferred from the tank night vision device, and it is a typical military technology converted to civilian use. In the 1950s, in order to improve the night maneuverability of tanks, equipment and instruments with night vision capabilities were installed on tanks, allowing tanks to move freely at night. Entering the 21st century, in order to improve the safety factor of cars driving at night, major car companies all over the world have installed night vision equipment on high-end cars to form a vehicle-mounted night vision assisted driving system. [0003] Vehicle-mounted night vision assisted driving systems can be divided into active infrared night vision systems and passive infrared night vision systems, mainly using active infrared i...
