Early warning and risk aversion system for preventing tailgating of vehicles under high-speed driving state

Abstract

The invention discloses an early warning and risk aversion system for preventing tailgating of vehicles under a high-speed driving state. The system includes a signal acquisition module, a control module and an execution module. The signal acquisition module includes a laser ranging sensor and photoelectric sensors. The control module includes a signal processor and a comparison circuit. The execution module comprises a display, a buzzer and an auxiliary brake device. The laser ranging sensor and the photoelectric sensors are respectively connected with input terminals of the signal processor,output terminals of the signal processor are respectively connected with an input terminal of the comparison circuit and the display, and an output terminal of the comparison circuit is connected with the buzzer and the auxiliary brake device respectively; the laser ranging sensor and the photoelectric sensors are mounted on the head of a vehicle, the display and the buzzer are installed inside the vehicle, and the auxiliary brake device is connected with a brake pedal of the vehicle. The system has the advantages of being intuitive and reliable, and has a prominent alarm effect, and automatic braking can be performed when braking measures are not adopted by a driver in time.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety alarms, in particular to a rear-end collision prevention early warning and risk avoidance system for vehicles running at high speed Background technique [0002] In recent years, with the rapid development of the domestic economy, the number of cars has increased year by year, the construction of expressways has become more and more perfect, and the speed of cars has become faster and faster. This makes life more convenient, but at the same time, the incidence of car accidents on expressways remains high. Among them, rear-end collisions are a major factor in the frequent occurrence of expressway accidents. Timely judge the deceleration or braking behavior of the vehicle in front and respond accordingly. [0003] At present, most low-end and middle-end cars do not have safety alarms and intelligent avoidance systems for the deceleration and braking behavior of the vehicle in front. Therefo...
