Embodiment 1

[0045]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.

[0046] Assume that the current vehicle speed transmitted by the current vehicle speed measurement sensor to the central control MCU is 80km / h, and the recommended braking distance at the current vehicle speed is 18m. When the obstacle distance measured by the obstacle distance measurement sensor is equal to or very close to 18m, and the driver When there is no braking action, the central control MCU starts to start the internal quadrature configuration optimization algorithm, and outputs braking instructions to the brake unit according to the calculation results.

[0047] The execution process of the internal orthogonal configuration optimization algori...

Abstract

The invention discloses an automobile automatic braking device based on orthogonal configuration optimization. The automobile automatic braking 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. 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 automatically executes an interior orthogonal configuration algorithm to calculate the optimum braking force and transmits a braking instruction to the brake unit according to the obtained optimum braking force 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, and mainly relates to an automatic braking device for automobiles based on orthogonal configuration optimization. In an emergency, the car can be automatically slowed down or stopped, and at the same time, the driver can obtain the most 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) sy...
