Automotive active braking system

Abstract

The invention discloses an automotive active braking system. The system comprises a distance sensing module, a speed acquiring module, a braking module, a warning module and a control module, wherein the control module comprises a calculating unit, a judging unit and an executing unit, the calculating unit is used for calculating the shortest braking distance according to the current speed of an automobile, obtaining warning distance by adding preset buffering distance to the shortest braking distance and obtaining braking distance by adding preset isolation distance to the shortest braking distance, the judging unit is used for sending a warning instruction to the executing unit when the distance between the automobile and an obstacle in front is smaller than or equal to the warning distance and sending a braking instruction to the executing unit when the distance between the automobile and the obstacle in front is smaller than or equal to the braking distance, and the executing unit is used for controlling the warning module to give a warning prompt to a driver after receiving the warning instruction and controlling the braking module to brake the automobile after receiving the braking instruction. By the adoption of the system, car accidents can be effectively avoided.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an automobile active braking system.
