Embodiment Construction

[0042] Below, based on Figure 1 ~ Figure 5 The gas stop early warning system according to the embodiment of the present invention will be described.

[0043] figure 1 It is a schematic diagram showing the schematic structure of a stopper warning system according to an embodiment of the present invention. Such as figure 1 As shown, the congestion warning system 1 mainly includes a detection unit 10, which is a sensor or radar installed in the vehicle, and is used to measure the relative distance with other vehicles, for example, it has a detection unit 10 installed in front of the vehicle. The first detection unit 11, the second detection unit 12 provided at the rear of the vehicle, and the third detection unit 13 provided at the side of the vehicle; the arithmetic control unit 20, which performs rearward detection based on the detection data of the aforementioned detection unit 10 Car fast approaching calculation control and rear oncoming vehicle congestion calculation control...

Abstract

The invention provides a queue jumping early warning system and method. The queue jumping early warning system comprises a detection part arranged on an own vehicle and used for measuring the relativedistances between other vehicles around the own vehicle and the own vehicle, and a computing control part used for conducting queue jumping computing control of the following vehicles on the basis ofdetected data of the detection part. Other vehicles and the road environment change can be detected and analyzed in real time through the detection part, the traveling tracks of other vehicles are predicted, a queue jumping vehicle intending to overtake and change the lane into the lane of the own vehicle from the rear side is judged, and an early warning and a prompt are given to a driver of theown vehicle in a proper mode. The driver can be warned about the danger in advance, prejudgment time is prolonged, and risks of emergency braking and accidents are reduced.

Description

Technical field [0001] The invention relates to a gas stop early warning system and a gas stop early warning method. Background technique [0002] As a safe driving assist system, there is currently known on the market a warning function LCA that reminds vehicles behind to approach quickly. In addition, with regard to the judgment of vehicle congestion, there is a warning for vehicle congestion in the adjacent lane in front of the vehicle, or the function of adjusting the distance between the vehicles in conjunction with ACC (Adaptive Cruise System). However, there is no predictive function of congestion for vehicles coming from behind. [0003] The inventor of the present application learned from the analysis of the cause of sudden braking on urban roads, and a large number of samples showed that in the case of a rapid approach from the rear and finally a sudden jam in front of the own vehicle, the own vehicle adopts a sudden brake to avoid a collision. [0004] However, such sudd...
