Embodiment 1

[0048] 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.

[0049] 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 precise penalty optimization algorithm, and outputs braking instructions to the brake unit according to the calculation results.

[0050] The execution process of the internal precise penalty optimization algorithm in the centra...

Abstract

The invention discloses a car automatic brake device based on accurate punishment optimization. The car automatic brake device based on accurate punishment optimization is composed of an obstacle distance measuring sensor, a current speed measuring sensor, a car center control MCU, a brake unit and equipment capable of alarming and displaying a state in the time of emergency brake. Brake parameters corresponding to a car model are input into the center control MCU and then the obstacle distance measuring sensor and the current speed measuring sensor are started to measure a distance from an obstacle ahead and a current speed in real time. When the distance from the obstacle is equal to a proposal brake distance under the current speed and a driver does not brake, the center control MCU automatically performs an internal accurate punishment optimization algorithm, calculates out the optimal brake force and sends a braking order to the brake unit according to the obtained optimal brake force so that the car can stop before making contact with the obstacle and an emergency brake warning signal is sent to the driver. The car automatic brake device based on accurate punishment optimization can avoid collision accidents as braking is not carried out in the process of driving a car in time.

Description

technical field [0001] The invention relates to the field of automobile safety, and mainly relates to an automobile automatic braking device based on precise penalty 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) system can reduc...
