Vehicle safety protection method and device

Abstract

The invention discloses a vehicle safety protection method and device. The vehicle safety protection method comprises the steps that threshold values are set; the travelling speed of a vehicle, the relative speed and the vehicle distance between the vehicle and a front vehicle, and surrounding obstacles are detected and compared with the set threshold values; whether detected data are larger thanthe set threshold values or not is analyzed; if the detected data are larger than the set threshold values, alarm is issued; and when a driver does not take deceleration or acceleration braking measures within 0.8 second, a system conducts emergency braking and increases the distance between the vehicle and the front vehicle or a rear vehicle in a forced mode. The steps are matched with an information acquisition module, an information processing and control unit, an execution module, a storage module and a power supply unit in the device to be implemented, the travelling speed of the vehicleis controlled within the safe travelling speed range, meanwhile, the vehicle is all-dimensionally monitored in real time, the timely alarm function is provided, the rear-end accident rate is effectively decreased, and when the two vehicle collide, the vehicle active safety protection device is automatically started, so that the travelling safety is improved all-dimensionally.

Description

technical field [0001] The invention relates to the technical field of automobile safety protection, in particular to an automobile safety protection method and device. Background technique [0002] In recent years, my country's highway construction has developed rapidly, the number of automobiles has increased sharply, and traffic accidents have occurred frequently. Automobile rear-end collision is one of the main forms of expressway traffic accidents, which has caused great economic losses to the country and individuals. [0003] Among them, the traffic accident rate caused by the driver's human factors is the highest, and both the number of accidents and the number of casualties are as high as about 90% of the total respectively. Moreover, fatigue and distracted driving are one of the important reasons among the driver's human factors that lead to these traffic accidents. The driver's inattention within 3 seconds caused 80% of the traffic accidents, mainly reflected in r...

Problems solved by technology

Moreover, fatigue and distracted driving are one of the important reasons among the driver's human factors that lead to these traffic accidents. The driver's inattention within 3 seconds caused 80% of the traffic accidents, mainly reflected in rear-end collisions. Accidents, the existing vehicle safety systems have carried out considerable effective explorations in order to prevent lane departure and maintain a safe distance between vehicles, including using sensors such as radar, laser, ultrasonic, and infrared around the car body to detect the distance between two vehicles, When the distance between the two vehicles is too close, the early warning unit is controlled by the control module to issue an early warning to the driver. The above-mentioned car safety warning system can remind the car owner to a certain extent and play a good role in preventing rear-end collisions. There are still deficiencies in this aspect. When the driver is tired or distracted, the driver does not react in time before the accident, and the above-mentioned system cannot actively slow down or accelerate, and the distance between the front car or the rear car can be opened to maintain a safe car. distance
