Problems solved by technology

[0004] However, based on the current technical level, automatic driving has not yet reached the stage of complete automation, because special road conditions or traffic conditions that cannot be solved by automatic driving may be encountered during driving, and the driver needs to monitor the vehicle
In the prior art, there is no intuitive reminder method that reflects the urgency of the current takeover vehicle, and the warning effect is not good

Embodiment Construction

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0066] According to the automation classification standard of SAE Inernaional, vehicles with automatic driving attributes of Level 4 and below can only perform automatic driving tasks within the special design use range (ODD). As the level of autonomous driving increases, the higher the degree of automation of the vehicle, the wider the available ODD. For Level 4 self-driving vehicles, fully automatic driving can be achieved within the ODD, but once the...

Abstract

The invention provides an automatic driving vehicle takeover reminding device. The automatic driving vehicle takeover reminding device comprises a journey information obtaining module, an environmental information obtaining module, a traveling time forecasting module, an emergency state judging module, a reminding mode control module and a reminding module, wherein the journey information obtaining module is used for obtaining journey information from a navigation system, the environmental information obtaining module is used for obtaining environmental information relevant to the journey, thetraveling time forecasting module is used for calculating the forecast traveling time according to the obtained journey information and environmental information and calculating the current remainingtime of automatic driving according to the forecast traveling time, the emergency state judging module is used for judging the magnitude relationship between the current remaining time and the presettime threshold value to generate the emergency state judging result, the reminding mode control module is used for generating takeover reminding information according to the emergency state judging result, and the reminding module is used for conducting reminding according to takeover reminding information. By degrading the reminding emergency degree, the better reminding effect can be achieved,and more intelligence is achieved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to the field of vehicles with automatic driving functions. Background technique [0002] An autonomous vehicle is a smart car that realizes unmanned driving through a control module. Self-driving cars rely on artificial intelligence, visual computing, radar, monitoring devices and global positioning systems to work together so that the control module can automatically and safely operate the motor vehicle without any active human operation. [0003] SAE Inernaional (International Society of Automotive Engineers) divides automatic driving systems (also known as unmanned driving systems) into six stages: no automation (Level 0), driver assistance (Level 1), partial automation (Level 2), and conditional automation (Level 2). Level3), highly automated (Level4), fully automated (Level5). No automation means the human driver has full control over the car, assisted by warning and protection system...
