Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] The present invention provides a method for following a blind spot in a curve based on the Internet of Vehicles, such as figure 1 shown, including the following steps:

[0030] Step 1: Follow the vehicle in front to enter the curve, and obtain the information of the vehicle in front, the vehicle and the environment of the curve.

[0031] CCD can be installed on the front bumper of the vehicle, and the industrial camera can be used to transmit the position information of the vehicle ahead and the curve environment information to the electronic control unit ECU; there are 3 vehicle radars, one of which is set in the middle of the front bumper of the vehicle , and the other two are respectively placed at both ends of the front bumper, which are used to detect the relative distance information between the own car and the front car and transmit it to the electronic contr...

Abstract

The invention discloses an automobile curve blind zone following control method based on the Internet of automobiles. The method comprises the steps of building an automobile curve safety following distance equation according to the speed and the relative distance, obtained by an Internet of automobiles system, of a front automobile and the driving information, obtained by a sensor carried by theautomobile when the front automobile does not enter a curve driving blind zone; extracting the characteristics of a driving environment image collected by a automobile-mounted CCD camera and the frontautomobile; determining a characteristic disappearance edge line of the road image in front of the driving direction, namely the boundary of an automobile detection blind zone; identifying the distance from the automobile to the boundary of the blind zone, meanwhile, identifying the relative positions of the front automobile tail and the blind zone boundary line; when the boundary lines of the front automobile tail and the blind zone are overlapped, enabling a main control ECU to make a following target and transfer the following target from the front automobile to the blind zone boundary line, obtaining the speed of the automobile in a blind zone through an Internet of Automobiles V2V system, fusing the speed and the identified blind zone boundary to form a virtual blind zone boundary following model with the speed, so that the automobile safely passes through a curve according to the following model.

Description

technical field [0001] The invention relates to a vehicle network-based control method for following blind spots in vehicle curves, and belongs to the technical field of vehicle driving safety. Background technique [0002] Adaptive Cruise Control System (ACC, Adaptive Cruise Control System), as an essential part of assisted driving, can improve driving safety, can replace the driver to control the speed of the vehicle, and avoid frequent cancellation and setting of cruise control, making the cruise system suitable for more The road conditions provide the driver with a more relaxed driving method. However, when following the vehicle in front to enter a curve, if the vehicle in front enters the blind spot of the curve, the following target of the own vehicle will be lost instantly, and the driver's field of vision is limited when driving in a curve, and insufficient information interaction between vehicles can easily cause traffic accidents happened.
