Abstract

The embodiment of the invention discloses a method and device for adjusting a vehicle speed. The method includes the steps that human eye recognition information of a driver is acquired, wherein the human eye recognition information includes pupil size and / or blink frequency; whether the human eye recognition information changes compared with prestored normal human eye recognition information is detected; if the detection result is yes, a vehicle is controlled to adjust the vehicle speed. By means of the method and device, the vehicle speed can be automatically controlled when emergencies happen in the driving process so that more response time can be won for the driver, and the probability of dangers is lowered.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a method and device for adjusting vehicle speed. Background technique [0002] At present, driving hazards can be avoided in various ways, such as detecting obstacles encountered outside the car through infrared, radar and other sensors. If an obstacle is encountered, the driver will be warned to control the vehicle accordingly; When there is a bad state such as fatigue driving, the driver is warned to drive normally. However, the above methods all require the driver to control the vehicle. When the driver encounters an unexpected situation, the reaction time is limited, and the vehicle speed cannot be controlled in time, which will still increase the probability of danger. Contents of the invention [0003] Embodiments of the present invention provide a method and device for adjusting vehicle speed. By adopting the embodiment of the present invention, the speed of th...
