Vehicle AEB system control method and device

Abstract

The invention discloses a vehicle AEB system control method and device, an AEB system has two working modes, namely a first mode and a second mode, and the first mode supports output of an early warning signal and a brake signal; the second mode only supports the output of the early warning signal; the control method comprises the following steps: S1, detecting whether the IMU system is normally started, and if yes, entering S20; if not, making the AEB system work in a second mode; S20, acquiring attitude information of the vehicle, judging whether the attitude information exceeds a thresholdvalue, and if yes, enabling the AEB system to work in a second mode; if not, entering S21; S21, making the AEB system work in a first mode and calculate a brake threshold value according to the attitude information, and outputting a corresponding early warning signal and a brake signal by the AEB system according to the brake threshold value; by the adoption of the control method, the AEB system can adapt to the current state of the vehicle, the first mode or the second mode is automatically selected to be used for work, and therefore the automatic protection effect of the AEB system is guaranteed to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of vehicle AEB system control, in particular to a vehicle AEB system control method and device. Background technique [0002] With the increase of car ownership year by year, the incidence of traffic accidents has also increased significantly, and people are paying more and more attention to car safety. During this process, many safety measures have emerged in the field of automobile safety. Among them, the automatic emergency braking system (Autonomous Emergency Braking, also called AEB system) is an active safety braking system used in scenarios where there is a risk of collision. In the event of a risk of collision, the AEB system can provide warning and braking operations according to the degree of danger. [0003] The existing AEB system still has many deficiencies in the formulation of handling strategies for dangerous working conditions. The main performance is that the application scenarios are gen...

Problems solved by technology

[0003] The existing AEB system still has many deficiencies in the formulation of handling strategies for dangerous working conditions. The main performance is that the application scenarios are generally relatively single, and the environment and vehicle body conditions are not fully considered. If the AEB system still executes the automatic braking function according to the normal road surface environment parameters, there may be a rolling or rollover accident
