Embodiment Construction

[0019] The concrete implementation of the present invention is described in detail below, it is necessary to point out here that the following implementation is only used for further description of the present invention, and can not be interpreted as limiting the protection scope of the present invention. Some non-essential improvements and adjustments still belong to the protection scope of the present invention.

[0020] The invention provides a vehicle collision avoidance method based on width detection, which is mainly aimed at detecting the width of the passing space in advance to remind the driver when the vehicle passes through the driving space and the vehicle cannot pass or is difficult to pass due to the narrow space, so as to select Reasonable driving style. Such as figure 1 , 2 As shown, when car 1 passes through the front door opening, if the width of the car is greater than the width of the door opening, then the car cannot pass through. For novices who lack dr...

Abstract

An automobile collision avoidance method based on width detection comprises the following steps that initialization is conducted, then angles of detection directions of a first distance detector and a second distance detector which are arranged on the positions, away from each other by the distance of L, on the two sides of the center position of a vehicle head of an automobile are calibrated, and the angle adjustable range is subjected to calibration in advance; according to margin parameters of an anterior travelling space detected by the first distance detector and the second distance detector, the width of the travelling space is calculated, and the alarm is given; according to the detected width value, the travelling direction of the automobile is adjusted; and through the step of the travelling space, according to the automobile collision avoidance method, the function that the travelling space width is pre-judged in advance to avoid collision is achieved, and the driving skill of a driver is effectively improved, so that accident occurrence probability is reduced.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an automobile collision avoidance method based on width detection. Background technique [0002] During the driving process of the car, collision accidents between the car and the front and rear vehicles, or with the surrounding environmental facilities often occur. Accidents will not only cause damage to vehicles and collision objects, but also cause economic losses, and sometimes cause injuries to drivers and passengers. Therefore, it is of great significance to effectively avoid accidents. [0003] At present, the early warning of accidents is usually realized by means of radar detection, reversing images, etc., and an alarm is issued by detecting or displaying surrounding obstacles to remind the driver. However, most of these methods can only be implemented under certain conditions. For example, the radar only starts to alarm within a certain detection range, and the reversi...
