Abstract
The invention discloses an automatic car collision avoidance method which comprises a central processing unit signal, an infrared speed measuring unit, a car speed measuring unit, an obstacle size measuring unit, an alarm unit and a safety trigger device. The automatic car anti-collision method comprises the steps of detecting the size, shape and speed of an obstacle according to the obstacle on a road, judging the distance between the obstacle and a car, sending an alarm signal if the distance exceeds a safe distance, enabling an alarm lamp to flash, starting a safety trigger device, enabling the car to decelerate, and avoiding collision.
Description
Technical Field
The invention belongs to the field of car safety, and relates to an automatic car collision avoidance method and method.
Background
With the increasing possession of private cars, the roads in cities are becoming increasingly congested. Accidents of collisions of cars often occur. The device is invented to reduce the occurrence of accidents.
Disclosure of Invention
The invention provides an automatic car anti-collision method, which can judge the size, shape and speed of an obstacle when a car runs on a road, measure the distance between the car and the obstacle, and judge whether to alarm or not and whether to start a safety trigger device or not by combining the speed of the car.
The invention provides an automatic car collision avoidance method, which comprises the following steps:
the vehicle speed measuring module is used for measuring the real-time speed of the vehicle;
the obstacle detection unit is used for detecting the size and the shape of an obstacle and the real-time speed of the obstacle;
the central processing unit is used for receiving data information fed back by the vehicle speed measuring module and the obstacle detecting unit and judging whether the vehicle is in an accident range of the obstacle or not according to the data information;
the alarm unit is used for starting alarm according to the instruction of the central processing unit;
the vehicle speed measuring module, the obstacle detecting unit and the alarming unit are respectively in signal connection with the central processing unit.
Further, the obstacle detection unit comprises a camera for capturing image information of the obstacle and a distance meter for measuring the distance between the vehicle and the obstacle.
An automatic car collision avoidance method is characterized by comprising the following steps:
(1) the infrared velocimeter detects whether an obstacle is in front of, behind or on the side of the car;
(2) the distance meter measures the distance between the vehicle and the obstacle, measures the real-time speed of the obstacle, and transmits the measured data to the central processing unit;
(3) the obstacle size determination unit measures the size and shape of an obstacle and transmits the measurement data to the central processing unit;
(4) the vehicle speed measuring module measures the real-time speed of the vehicle and transmits the measured data to the central processing unit;
(5) and (4) processing by the central processing unit according to the data obtained by measurement in the step (3) and the step (4), judging whether the vehicle is in the accident range of the obstacle, and if so, sending an alarm signal to an alarm unit to trigger the whole equipment.
