Problems solved by technology

[0002] Some drivers are affected by factors such as inattention, fatigue, drugs, emotions and weather when driving, resulting in the distance between the vehicle, obstacle or pedestrian in the same lane or the distance between the vehicle, obstacle or pedestrian when reversing. Misjudgment, so that the distance between two vehicles, vehicles or vehicles is equal to or less than the vehicle braking distance (critical safety distance) of the real-time speed, which will easily cause road traffic accidents.
[0003] At present, there are no scientific and technological documents similar to the automatic braking system of automobiles applicable to four types of road surfaces

Abstract

The invention discloses an automobile automatic braking system applicable to four types of pavement and a control method thereof; the system comprises an electronic controller, a detection device, an actuation device and a power module. The control method comprises the following steps that the electronic controller calculates a real-time automobile braking distance through a real-time automobile driving speed and a pavement driving environment, measures the real-time distances between two vehicles on the same lane, a vehicle and an object, a vehicle and a person through a ranging sensor, sends out a control instruction according to a control program, brakes a vehicle and gives out a voice alarm. The automobile automatic braking system has the characteristic of high intelligentization degree, and can ensure safe driving on the pavement in different environments.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an automobile automatic braking system applicable to four road surfaces and a control method thereof. Background technique [0002] Some drivers are affected by factors such as inattention, fatigue, drugs, emotions and weather when driving, resulting in the distance between the vehicle, obstacle or pedestrian in the same lane or the distance between the vehicle, obstacle or pedestrian when reversing. Misjudgment makes the distance between two vehicles, vehicles or vehicle people equal to or less than the vehicle braking distance (critical safety distance) of the real-time speed, so that it is very easy to cause road traffic accidents. [0003] At present, there is no scientific and technological literature similar to the automobile automatic braking system applicable to four types of road surfaces. Contents of the invention [0004] In order to solve the problems in the...
