An Active Vehicle Rear Auxiliary Early Warning System

Abstract

The invention discloses an active vehicle rear auxiliary pre-warning system. The active vehicle rear auxiliary pre-warning system comprises a central processor unit as well as a vehicle-mounted camera unit, a radar sensor, an audible alarming system and an electronic lock controller, wherein the vehicle-mounted camera unit, the radar sensor, the audible alarming system and the electronic lock controller are connected with the central processor unit; the central processor unit is used for identifying specific positions of outside dangerous factors according to video image information, transmitted by a camera, and detecting information, transmitted by an ultrasonic detector, and is used for transmitting an instruction to the audible alarming system and the electronic lock controller; the audible alarming system is used for transmitting voice alarm; and the electronic lock controller is used for controlling short-time vehicle door locking. According to the invention, through the adoption of the active pre-warning system, the system is used for actively performing protecting actions after the central processor computer judges camera-collected information; meanwhile, the central processing unit actively interferes with vehicle behaviors and warns personnel in the vehicle through the audible alarming system so that pre-warning failure caused by unconscious behaviors of passengers due to not understanding meanings expressed by an alarming signal is avoided.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to an active vehicle rear auxiliary early warning system. Background technique [0002] With the attention to car safety performance, various driving assistance warning systems such as forward collision avoidance warning system and lane departure warning system have been applied more and more. Give the driver corresponding warning or prompt information before the situation occurs, so as to avoid the occurrence of accidents. But for the current driving assistance early warning system, there are two problems in the early warning. One, these early warning signals are mostly arranged on the instrument panel, which, while causing a burden on the necessary space of the instrument panel, also requires the driver to divert the line of sight to check its alarm content, which is easy to disperse the driver's attention, thereby causing new problems. security risks. Second, the warning informat...

Problems solved by technology

One, these early warning signals are mostly arranged on the instrument panel, which while causing a burden on the necessary space of the instrument panel, also requires the driver to divert the line of sight to check its alarm content, which is easy to disperse the driver's attention, thereby causing new problems. security risks

Second, the warning information of the commonly used early warning system is similar, which is easy to cause misunderstanding and confusion for the driver, because the driver needs to process and analyze the driving state according to the current driving environment during the driving process, which is a complicated method. In the process of information processing, for inexperienced drivers, ordinary alarm patterns and early warning sounds such as "didi" and "beep" are not enough for them to quickly and effectively understand the current dangerous situation, so that they cannot quickly Make the correct response, affecting the actual early warning effect
