Vehicle pre-crash system

Abstract

The invention discloses a vehicle pre-crash system which is provided with a vehicle speed judgment module, a preposition radar unit and a crash calculation unit, wherein the vehicle speed judgment module is in communication connection with a vehicle bus to acquire current vehicle speed per hour; the preposition radar unit acquires a distance from and a position of a front vehicle in real time; the crash calculation unit calculates a minimum braking distance via the current vehicle speed per hour; the obtained minimum braking distance is compared with the distance from the front vehicle to judge whether unavoidable crash occurs; and the unavoidable crash is defined as follows that the minimum braking distance is greater than the distance from the front vehicle. With the adoption of the technical scheme, according to the vehicle pre-crash system, the corresponding crash judgment unit is arranged to effectively reduce crash probability of a vehicle; and even if the unavoidable crash occurs, auxiliary brake measures and corresponding safety measures can be adopted to effectively protect passengers in the vehicle. The adopted technology is mature, and the system is very suitable for extensive popularization among the vehicles.

Description

technical field [0001] The invention relates to a vehicle pre-collision system. Background technique [0002] With the continuous development of technology, more and more advanced technologies, especially active safety technology, have begun to be applied to automobiles. Traditional vehicles lacking active safety technology do not have corresponding preventive measures when they collide with other objects, resulting in heavy losses to the vehicle and the occupants, and can easily cause car crashes and fatalities. Contents of the invention [0003] The present invention aims at the above problems and develops a vehicle pre-collision system, which has: [0004] The vehicle speed determination module is connected with the vehicle bus to obtain the current vehicle speed; [0005] The front radar unit can obtain the distance and position of the vehicle in front in real time; [0006] The collision calculation unit calculates the minimum braking distance based on the current ...
