- the distance between the vehicle's position and the first state switching point on the road gradually shortens, corresponding to the emergency degree of the vehicle being taken over. increases, then the driver can be reminded to take over the vehicle as soon as possible by gradually increasing the font size of the text corresponding to the takeover prompt information, so that the driver can learn the urgency of taking over the vehicle through the font size of the text corresponding to the takeover prompt information. , take over the vehicle as soon as possible to ensure the driving safety of the vehicle.
- the driving object can intuitively understand the driving progress of the vehicle through the driving progress bar.
- the distance between the current position of the vehicle and the first state switching point is judged, and the urgency of the vehicle being taken over is judged based on the distance, and the vehicle is taken over as soon as possible. vehicles to ensure the driving safety of the vehicle.
- the driving subject may be familiar with the route to the destination and does not need the navigation map to guide to the destination. Then, display the exit control corresponding to the navigation map, When the driving subject is familiar with the path in the navigation map, the navigation map can be exited by triggering the exit control, thereby effectively reducing the operating consumption of the computing device and improving the operating efficiency of the computing device.
- the exit control can be displayed to facilitate the driver to choose to cancel the display of the navigation map when the vehicle can be driven without the navigation map.
- the state switching prompt information is displayed in the map navigation interface so that the driving object can switch to automatic driving in time when it needs to switch to automatic driving state. state, thereby reducing the driving burden on the driving subject, and can effectively play the role of the autonomous driving state and reduce the driving burden on the driving subject.
- the driving subject can accurately know the switching timing from the manual driving state to the automatic driving state.
- the switching conditions are obtained If the conditions are met, switching to the automatic driving state as soon as possible can effectively play the role of the automatic driving state and reduce the driving burden of the driving subject.
- the second style in the assisted driving interface to display at least one drivable lane corresponding to the target position of the vehicle, the drivable lanes and lanes other than the drivable lanes can be effectively distinguished in the assisted driving interface.
- the highlighted display of the lane can accurately know the driving route of the taken over vehicle, thereby ensuring the driving safety of the vehicle.
