Embodiment 1

[0041] Assuming that the car is driving on the highway, the obstacle distance measurement sensor and the current vehicle speed measurement sensor on the car have been turned on. An obstacle suddenly appears on the road ahead at a certain moment, and the driver does not realize that an accident may occur due to fatigue driving.

[0042] Assuming that the current vehicle speed transmitted by the current vehicle speed measurement sensor 2 to the central control MCU3 is 80km / h, the recommended braking distance under the current vehicle speed is 18m, when the obstacle distance measured by the obstacle distance measurement sensor 1 is equal to or very close to 18m, and When the driver does not perform any braking action, the central control MCU3 starts the internal dynamic optimization method, and outputs a braking command to the brake unit 4 according to the calculation result.

[0043] The internal dynamic optimization method in the central control MCU - the execution process of the...

Abstract

The invention discloses an automobile automatic braking device based on dynamic optimization. The device is formed by an obstacle distance measuring sensor, a current automobile speed measuring sensor, an automobile central control microprogrammed control unit (MCU), a brake unit and an emergency braking alarming and state displaying device. All the parts are connected through a data bus in an automobile. After a braking parameter corresponding to the automobile type is input in the central control MCU, the obstacle distance measuring sensor and the current automobile speed measuring sensor are started to measure the front obstacle distance and current automobile speed in real time. When the obstacle distance is equal to the suggested braking distance under the current automobile speed and a driver does not conduct braking action, the central control MCU acquires the optimum braking force and transmits a braking instruction to the brake unit to enable the automobile to stop before the automobile is in contact with the obstacle. By means of the automatic braking device, collision accidents caused by the fact that the driver does not conduct braking timely in a driving process are avoided, the driver can obtain more braking time for buffering, and emergency braking can be avoided.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an automobile automatic braking device based on a dynamic optimization method which can automatically decelerate or stop an automobile when an emergency occurs so that a driver can obtain more braking time. Background technique [0002] During the driving process, due to fatigue, answering the phone, being attracted by other things, etc., it is easy for the driver to fail to deal with sudden emergencies in time, resulting in collisions or even accidents. [0003] With the development of automobile technology, people's requirements for safer car use have become increasingly strong. At present, some foreign high-end models such as Infiniti M series and Volvo S60 have begun to be equipped with automatic braking control devices, and their principles are different. Statistics show that vehicles equipped with the Autonomous Emergency Braking (AEB system) system can reduce the accident...
