Embodiment 1

[0058] figure 1 An exemplary embodiment of the present application provides a steering wheel information early warning method when the vehicle exits automatic driving, the early warning method includes:

[0059] Step S1. When it is detected that the vehicle exits the automatic driving, it is judged whether the driver actively takes over the vehicle, wherein, if yes, determine that the exit mode of the vehicle exiting the automatic driving is the active takeover mode, and if not, determine the exit mode of the vehicle exiting the automatic driving Takeover mode for exception;

[0060] Specifically, when it is detected that the vehicle exits automatic driving, it is first judged whether the driver is actively taking over the vehicle, refer to figure 2 As shown, the judgment process mainly includes the following:

[0061] When it is detected that the vehicle exits automatic driving, determine the current driving scene of the vehicle;

[0062] If the current driving scene is a...

Embodiment 2

[0096] refer to Image 6 As shown, another exemplary embodiment of the present application also provides a steering wheel information early warning method when exiting automatic driving, and the early warning method includes:

[0097] Step S41. When the car exits the automatic driving mode, it is judged whether the exit mode of the automatic driving mode is the driver's initiative to take over, and a first judgment result is generated;

[0098] When the system exits the automatic driving mode, it first generates the first judgment result according to whether the exit is caused by the driver’s active takeover. According to the first judgment result, it will enter the normal takeover mode or the abnormal takeover mode. Active takeover, for example, the driver actively intervenes in the vehicle to change the current driving state of the vehicle. When the vehicle-machine system detects that the driving state has changed, it is considered that the driver actively changed the curren...

Embodiment 3

[0117]refer to Figure 9 As shown, an exemplary embodiment of the present application provides a steering wheel information early warning system when exiting automatic driving, the early warning system includes: automatic driving exit judgment module 501, mode determination module 502, steering angle acquisition module 503 and early warning module 504, of which,

[0118] The automatic driving exit judging module 501 is used for judging whether the driver actively takes over the vehicle when it is detected that the vehicle exits the automatic driving.

[0119] The mode determination module 502 is configured to determine that the exit mode of the vehicle to exit the automatic driving is the active takeover mode when the judgment is yes, and determine that the exit mode of the vehicle to exit the automatic driving is the abnormal takeover mode when the judgment is no.

[0120] The steering angle acquisition module 503 is configured to acquire the steering angle of the steering w...

Abstract

The invention discloses a steering wheel information early warning method and system during automatic driving quitting, and the method comprises the steps: judging whether a driver actively takes over a vehicle or not when detecting that the vehicle quits automatic driving, if yes, determining that the quitting mode of the vehicle quitting the automatic driving is an active take-over mode, and if not, determining that the vehicle quits the automatic driving is an active take-over mode; if yes, determining that the exit mode of the vehicle exiting the automatic driving is an abnormal takeover mode; acquiring a steering angle of a steering wheel when the vehicle exits automatic driving; if the steering angle is not zero, according to the exit mode, warning signals are generated based on the steering angle to conduct early warning, and the warning signals in different exit modes are different in early warning level. The problem that when an original vehicle exits from an automatic driving mode, safe driving of the vehicle is affected by factors such as non-alignment of a steering wheel is solved.

Description

technical field [0001] The present application belongs to the field of automobile automatic driving, and in particular relates to a steering wheel information early warning method and system when exiting automatic driving. Background technique [0002] Autonomous vehicles (Autonomous vehicles) is a kind of smart car that realizes unmanned driving through a computer system. [0003] The safety of autonomous driving has always been a concern of people. At present, when automatic driving is changed to manual driving, the data processing process and safety measures usually taken include: obtaining driving status information (steering or acceleration and deceleration) and generating prompt information; obtaining driving parameters and personal indicators when the automatic driving control is handed over Information to judge whether it is safe to judge whether to transfer control or resume automatic driving or decelerate to stop. [0004] In the current prompt scheme, when the a...
