Technique for operating a vehicle safely in a lane
View Patent ↗In a control and management system for automobiles, a central processor in the system connects traditionally unrelated vehicle subsystems together to realize synergistic functions such as smart driving, automatic parking, etc. A master interface having a display is employed in the system to help a user control and manage the vehicle functions.
1. A method for use in a system in a vehicle, comprising
detecting marking devices defining a lane in which the vehicle is moving, the marking devices being disposed on at least one side of the lane at a certain interval;
determining whether the vehicle is subject to improper steering in the lane based at least on detection of the marking devices;
providing an alert when no marking devices are detected on the at least one side of the lane for a predetermined number of intervals; and
generating a turn signal when a departure from the lane is indicated.
2. The method of claim 1 wherein at least one of the marking devices includes a magnet.
3. The method of claim 1 wherein the vehicle is steered automatically in the lane.
4. The method of claim 3 wherein automatic steering of the vehicle is terminated when the vehicle departs from the lane.
5. The method of claim 4 further comprising generating a message to inform a user of a termination of the automatic steering.
6. The method of claim 5 wherein the message is provided on a display element in the vehicle.
7. The method of claim 1 wherein the predetermined number of intervals are consecutive.
8. The method of claim 1 wherein the departure from the lane is indicated by manipulating an indicator provided on a display element in the vehicle.
9. The method of claim 8 wherein the indicator comprises an arrow indicating a direction in which the vehicle is moving.
10. The method of claim 1 wherein the marking devices are indicated on a display element in the vehicle.
11. A system for use in a vehicle, comprising
a device for detecting marking devices defining a lane in which the vehicle is moving, the marking devices being disposed on at least one side of the lane at a certain interval;
a processor configured to determine whether the vehicle is subject to improper steering in the lane based at least on detection of the marking devices;
an interface for providing an alert when no marking devices are detected on the at least one side of the lane for a predetermined number of intervals; and
a mechanism for generating a turn signal when a departure from the lane is indicated.
12. The system of claim 11 wherein at least one of the marking devices includes a magnet.
13. The system of claim 11 wherein the vehicle is steered automatically in the lane.
14. The system of claim 13 wherein automatic steering of the vehicle is terminated when the vehicle departs from the lane.
15. The system of claim 14 further comprising generating a message to inform a user of a termination of the automatic steering.
16. The system of claim 15 wherein the message is provided on a display element in the vehicle.
17. The system of claim 11 wherein the predetermined number of intervals are consecutive.
18. The system of claim 11 wherein the departure from the lane is indicated by manipulating an indicator provided on a display element in the vehicle.
19. The system of claim 18 wherein the indicator comprises an arrow indicating a direction in which the vehicle is moving.
20. The system of claim 11 wherein the marking devices are indicated on a display element in the vehicle.
