Embodiment 1

[0070] refer to figure 1 , shows a flow chart of a blind spot monitoring and warning method provided by an embodiment of the present invention, the method is applied to a vehicle, and includes the following steps:

[0071] S101. According to the preceding vehicle monitoring signal, monitor whether there is a preceding vehicle in an adjacent lane within a preset distance ahead of the own vehicle;

[0072] Specifically, since the method provided by the embodiment of the present invention is to actively monitor whether the self-vehicle enters the blind spot of other vehicles, it can be understood that the self-vehicle is the vehicle currently driven by the driver, and the front is the front of the self-vehicle. Position, that is, the direction in which the ego vehicle is moving.

[0073] When there is no vehicle in front of the self-vehicle, that is, there is no preceding vehicle driving ahead, obviously there is no obstacle blocking, and naturally there is no so-called blind ar...

Embodiment 2

[0082] refer to image 3 , shows a flow chart of another blind spot monitoring and warning method provided by an embodiment of the present invention, the method is applied to a vehicle, and includes the following steps:

[0083] S201. When the speed of the ego vehicle exceeds a preset speed threshold, send the preceding vehicle monitoring signal, wherein the monitoring signal is used to trigger the monitoring of the preceding vehicle adjacent to the ego vehicle.

[0084] Specifically, in order to avoid an alarm when the vehicle is running at a low speed, a preset speed can be set. When the driving speed of the own vehicle exceeds the preset speed threshold, it starts to monitor whether the adjacent lane within the preset distance in front of the own vehicle is Existence of prior vehicles. For example, when a vehicle is driving at a low speed on a relatively congested municipal road, the road itself is extremely congested and the vehicle speed itself is not high, it can be con...

Embodiment 3

[0114] refer to Figure 4 , the embodiment of the present invention provides a blind spot monitoring and alarming device, which is applied to a vehicle, and the device includes:

[0115] The first monitoring module 301 is configured to monitor whether there is a preceding vehicle in an adjacent lane within a preset distance ahead of the self-vehicle according to the preceding vehicle monitoring signal;

[0116] A calculation module 302, configured to calculate the blind spot range of the preceding vehicle when the preceding vehicle exists;

[0117] A judging module 303, configured to judge whether the own vehicle is in the blind spot;

[0118] An alarm module 304, configured to send an alarm message to the driver of the own vehicle if the own vehicle is in the blind spot.

[0119] The blind spot monitoring and alarm device described in the embodiment of the present invention can monitor whether there is a preceding vehicle in the adjacent lane within the preset distance in f...

Abstract

The embodiment of the invention provides a blind area monitoring and alarming method and device. The blind area monitoring and alarming method is applied to a vehicle, and comprises the steps of monitoring whether a preceding vehicle is in an adjacent lane at a preset distance from the front of the vehicle or not according to a preceding vehicle monitoring signal; when the preceding vehicle exists, calculating a blind area range of the preceding vehicle; judging whether the vehicle is in a blind area range or not; and if the own vehicle is located in the blind area range, sending first alarm information to a driver of the own vehicle. According to the embodiment of the invention, the current vehicle driver can be prompted that the vehicle is driven into the blind area range of the preceding vehicle, a danger early warning effect is achieved, the driver can be prompted to drive away from the blind area range, and the safety risk is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a blind spot monitoring and alarming method and device. Background technique [0002] With the advancement of science and technology, various safety technologies are used in automobiles. [0003] At present, when the vehicle is running, when the driver observes the surrounding traffic environment through the external rearview mirror, there is a certain range of blind spots in the field of vision. With the promotion of driving assistance technology, some vehicles are equipped with a blind spot monitoring system, relying on the radar installed at the rear of the vehicle to detect the traffic environment behind the vehicle side, if there are other vehicles in the blind spot, you can light the rearview mirror The way of the warning light reminds the driver of the current vehicle that there is a vehicle in the blind spot and needs to avoid it. [0004] However, the existing b...
