Problems solved by technology
[0004] The present invention is mainly aimed at when the vehicle is about to turn, if there is an oncoming vehicle in the opposite direction, when the driver cannot judge whether a collision will occur if the two vehicles do not decelerate, it can avoid such artificially ambiguous judgments. In the event of a collision

Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] The specific implementation system includes a front-view camera, which is installed on the windshield of the car, captures the image in front of the car and recognizes the oncoming vehicle, obtains relevant data of the oncoming vehicle and sends it to the system master;
[0036] The relevant data of the oncoming vehicle includes the longitudinal distance X and the lateral distance Y and the relative speed of the vehicle and the oncoming vehicle, and the angle is considered to be an ideal opposite 180° direction.
[0037] Including the main control of the system, the main control of the system obtains the speed, direction and expected driving path of the oncoming vehicle by receiving the relevant data processing of the oncoming vehicle identified by the front-view camera, and at the same time obtains the turn signal of the vehicl...

The invention discloses a steering auxiliary system based on a foresight camera. The foresight camera is installed in front of a vehicle and used for shooting images in front of the vehicle, recognizing an opposite coming vehicle, obtaining related data of the opposite coming vehicle and sending the related data to the system master controller. The system master controller processes to obtain the speed and the expected driving path of an opposite coming vehicle, obtains the steering lamp signal, the speed information and the steering wheel angle information of the vehicle through the CAN network of the vehicle, calculates the expected driving path of the vehicle during steering according to the information, and judges according to the expected driving paths of the opposite coming vehicle and the vehicle. A driving control signal is generated to control the driving work of the vehicle. The method mainly solves the problem that when a vehicle needs to turn left at an intersection, if a vehicle comes in the opposite direction, a driver cannot accurately judge whether the vehicle can pass in advance or not, so that a serious collision accident is possibly caused.
Description
technical field [0001] The present invention relates to a steering assistance system based on a front-view camera, in particular to a steering assistance system and a control method based on a front-view camera. Background technique [0002] With the improvement of living standards in various countries around the world, the number of automobiles continues to increase. At the same time, various traffic accidents and the resulting casualties and property losses are also increasing. my country's road traffic is relatively complex, and the vehicle models are also relatively complex. Relevant data show that about 30% of accidents are side collision accidents. The fatality rate of side collision accidents is second only to frontal collisions, but the injury rate ranks first. Contents of the invention [0003] In order to solve the problems existing in the background technology, the present invention provides a steering assistance system and control method based on a front-view ...
