Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] figure 1 Shown is the functional block diagram of the automobile active anti-collision system of the present invention. The automobile active collision avoidance system of the present invention includes a sensing unit 10 , a judging and decision-making unit 20 , and an executing unit 30 . The car recognizes its surroundings and its own environment through the perception unit 10 . The sensing unit 10 is the basis for the realization of the vehicle's active collision avoidance system, including information such as the relative distance from the vehicle to the target vehicle, the orientation of the target vehicle relative to the vehicle, the speed of the vehicle, the throttle position, and the brake pedal. The distance sensor 1 measures the relative distance from the vehicle to the target vehicle, the orientation sensor 3 measures the orientation of th...

Abstract

The invention relates to an active anti-collision system for a car, including: a sensing unit, a judgment and decision unit and an execution unit. The car recognizes the ambient environment and the own environment via the sensing unit consisting of sensors, the judgment unit consisting of a single chip machine and software controls and decides the operation of the system by receiving information sent by the sensing unit, the execution unit receives an instruction from the judgment unit, and gives an alarm and executes emergency automatic brake. In the invention, when the distance between the car and a barrier is less than a safety value, an alarm is given out, if the driver has no action, the system brakes automatically to avoid accidents. The invention is suitable for various motor vehicles with an electronic fuel injection control engine.

Description

[0001] technical field [0002] The invention relates to an automobile active anti-collision system, which belongs to the technical field of automobile safety. Background technique [0003] According to statistics, the occurrence of most traffic accidents is because the driver did not have time to react, so the current research mainly focuses on letting the driver know the danger in advance, that is, the car anti-collision warning system. Although this system reduces the incidence of traffic accidents, sometimes the driver has no time to brake even if the alarm is given. This requires a more intelligent system. When taking action, it can automatically brake. [0004] Announcement No. 200948775 discloses an autonomous vehicle anti-collision warning and protection device, which includes a central processing module, a road detection module, an alarm circuit, an airbag drive module, a protective airbag and an LED display module; The drive module issues instructions to drive...
