Abstract

A method and a device for the autonomous startup of a motor vehicle from a standing position, which is determined by a traveling sensor, is provided. The type of road for the current motor vehicle position is determined via a navigation device or environmental sensors. In specific types of roads, a preceding deceleration to a complete stop is followed by the automatic activation of an auto-go mode, in which a control unit initiates an autonomous startup of the vehicle by way of a startup unit once a startup acquisition unit has determined that the other motor vehicle has started up.

Claims

1. A method for an autonomous startup of a motor vehicle from a standing position when the startup of another motor vehicle located in front of the motor vehicle has been determined, comprising:

acquiring a type of road corresponding to the current motor vehicle position via a navigation device or environmental sensors; and

automatically activating an auto-go mode after a preceding deceleration to a complete stop for specific types of roads, in which the vehicle is autonomously started up as soon as a startup of the other motor vehicle has been determined

2. The method according to claim 1, wherein the auto-go mode is activated again if only at least one of a short distance is covered and a low top speed was reached after an autonomous startup and up until a renewed deceleration to a complete stop.

3. The method according to claim 1, further comprising:

automatically activating the auto-go mode if the type of road is a freeway, a highway, a multi-lane city roadway or a tunnel

4. The method according to claim 1, further comprising:

not activating the auto-go mode if the type of road has a speed limit of about 50 km/h or less.

5. The method according to claim 1, wherein the environmental sensors optically acquire traffic, road signs, direction signs.

6. The method according to claim 1, wherein the environmental sensors acquire traffic data transmitted by radio.

7. The method according to claim 1, further comprising:

determining the speed before the last deceleration process, and the auto-go mode is activated as a function thereof

8. The method according to claim 1, wherein a driver alertness recognition system acquires information about the alertness of the driver, and the method further comprises:

terminating an initiated startup process if an absence of alertness is determined after a specific time or covered distance; and

signaling the impending termination to the driver via at least one of an acoustic, optical and haptic warning, if necessary, making it possible to avoid the latter by way of a driver operating command.

9. The method according to claim 1, wherein the activated auto-go mode remains activated for the duration of an auto-go time window, and is deactivated thereafter.

10. The method according to claim 9, further comprising:

displaying at least one of the activation and remaining duration of activation of the auto-go mode to the driver at least one of visually, acoustically and haptically.

11. The method according to claim 10, wherein the auto-go mode can be activated or is deactivated via a driver operating command.

12. The method according to claim 1, wherein the environmental sensors are used to determine whether the other vehicle has activated a turn signal, wherein the auto-go mode is only activated if navigation route data have determined that the traveling direction of the other vehicle corresponds to the desired driving route of the motor vehicle.

13. The method according to claim 1, wherein the auto-go mode is only activated if environmental sensors have determined that no pedestrians or cyclists are in the vicinity.

14. A device for an autonomous startup of a first motor vehicle from a standing position, comprising:

a road type acquisition unit for determining the type of road;

a traveling sensor that determines that the first motor vehicle has come to a complete stop;

a startup acquisition unit for determining a startup of a second motor vehicle in front of the first motor vehicle;

at least one of an environmental sensor and a navigation device; and

a control unit.

15. The device according to claim 14, further comprising at least one of:

an auto-go mode display;

an auto-go mode actuator; and

a driver alertness recognition system.

16. A motor vehicle, comprising:

a road type acquisition unit for determining the type of road;

a traveling sensor that determines that the motor vehicle has come to a complete stop;

a startup acquisition unit for determining a startup of a second motor vehicle in front of the motor vehicle;

at least one of an environmental sensor and a navigation device; and

a control unit that;

automatically activates an auto-go mode after a preceding deceleration to a complete stop for specific types of roads, in which the motor vehicle is autonomously started up as soon as a startup of a second motor vehicle in front of the motor vehicle has been determined
