Embodiment Construction

[0061] It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

[0062]ADAS (Advanced Driving Assistance System) uses various sensors and satellite navigation installed on the car to sense the surrounding environment at any time during the driving process of the car, collect data, and identify and detect static and dynamic objects. And tracking, combined with navigation map data, to carry out systematic calculation and analysis, so as to make drivers aware of possible dangers in advance, effectively increasing the comfort and safety of car driving. The current vehicle departure warning can be completed through ADAS to prevent the vehicle from veering off the lane caused by the driver's unconsciousness and reduce the occurrence of traffic accidents.

[0063] However, in actual driving conditions, there are often differences in the user's perception of vehicle departu...

Abstract

The invention provides a speed-following early warning method and system for vehicle deviation and a vehicle. The method comprises the following steps: acquiring driving information; obtaining driving information; the driving information is analyzed, and whether the vehicle deviates from a lane or not is judged; under the condition that the vehicle deviates from the lane to run, vibration parameters corresponding to the current vehicle speed are obtained; and according to the vibration parameters, an EPS system motor is controlled to vibrate a vehicle steering wheel according to the amplitude and / or frequency corresponding to the vibration parameters. According to the method provided by the embodiment of the invention, when the vehicle deviates from the lane, the early warning of the corresponding intensity degree is sent out according to the current vehicle speed of the vehicle, so that the intensity degree of the vehicle deviation early warning is matched with the user perception degree and the danger degree of vehicle driving, and the early warning effect of vehicle deviation is improved; the occurrence rate of traffic accidents is reduced while the vehicle driving experience of the user is optimized.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a method, a system and a vehicle for speed following early warning of vehicle deviation. Background technique [0002] Cars are an important travel tool in people's lives. With the gradual change of cars and the great progress of computer technology, people have put forward higher requirements for the driving experience of cars, hoping to gain intelligence in the process of driving cars , Humanized driving assistance. [0003] At present, a considerable number of traffic accidents are caused by the driver's drowsiness or distraction while driving the vehicle, which leads to driving out of the lane unconsciously. After the vehicle deviates from the lane, there is a risk of collision with other vehicles or road guardrails. In the case of high-speed driving, it is especially likely to cause serious adverse consequences and even cause major traffic accidents. Therefor...
