Embodiment Construction

[0009] The working method of the front collision avoidance warning and driving assistance system provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] see figure 1 as well as figure 2 , the embodiment of the present invention provides a method for providing front collision avoidance warning and assisted driving by using a laser sensor, the specific method is as follows:

[0011] figure 1 It is the schematic diagram of the laser sensor front collision avoidance warning and assisted driving system. The laser sensor and the rotating platform are installed on the front part of the main body vehicle 11. The rotating frequency of the rotating platform is 15-30 Hz. With the rotation of the rotating platform, the laser sensor can realize the detection angle of 180 degrees. Among them, in the case of stillness, the detection angle of the laser sensor is 3 degrees, and the detection distan...

Abstract

The invention relates to a vehicle-mounted front anti-collision system utilizing a laser radar, which is characterized by comprising a wide-angle laser sensor, a one-dimensional rotating platform anda data processing module. Corresponding functions of early warning, automatic aided driving and the like can be realized according to relative vehicle speed and relative obstacle distance informationacquired by the laser sensor; and the vehicle-mounted front anti-collision system can be widely applied to front anti-collision early warning of an automobile, and more accurate reference informationis provided for a driver.

Description

technical field [0001] The invention relates to the warning and driving assistance fields of vehicle front collision avoidance warning, in particular to a dynamic and real-time front collision avoidance warning and driving assistance system and method thereof. Background technique [0002] As the main means of transportation in today's social life, the driving system of the car is gradually developing in the direction of automation and intelligence. As a part of the driving assistance system, the car's front collision avoidance warning can display the obstacles and road conditions in front of the car to the driver in the form of visual images, so as to avoid the existence of the driver's visual blind spot, or when the driver is distracted. Provide reminders or driving assistance functions in certain situations. However, the current front collision avoidance imaging systems all use optical cameras as the basic detection unit. Under the condition of insufficient external ligh...
