## Abstract

A method for switching over from a first driver assistance function to a second driver assistance function in a two-wheeled vehicle; one of the driver assistance functions being an adaptive distance and speed control function, and the other driver assistance function being a cruise control function; the switchover being accomplished by uninterrupted manipulation of an actuating element by the driver over a time interval of predefined length.

## Claims

### Claim 1

A method for switching over from a first driver assistance function to a second driver assistance function in a two-wheeled motor vehicle, the method comprising:
detecting a manipulation by a driver of an actuating element;
detecting that an adaptive distance and speed control function is currently active; and
based on the detecting that the adaptive distance control and speed control function is currently active, switching over from the adaptive distance and speed control function to a cruise control function by deactivating the adaptive distance and speed control function and activating the cruise control function;
wherein the switching over is performed only when the manipulation by the driver of the actuating element is an uninterrupted manipulation of the actuating element by the driver over a time interval of predefined length to accomplish the switchover; and
wherein the adaptive distance and speed control function has a lower maximum speed than a maximum speed of the cruise control function.

### Claim 2 (depends on 1)

The method of claim 1, wherein the actuating element is a push-button switch.

### Claim 3 (depends on 2)

The method of claim 2, wherein the push-button-switch is the same push-button switch is used for activating the adaptive distance and speed control function.

### Claim 4 (depends on 1)

The method of claim 1, wherein the time interval of predefined length is greater than two seconds.

### Claim 5 (depends on 4)

The method of claim 4, wherein the time interval of predefined length is approximately three seconds.

### Claim 6 (depends on 1)

The method of claim 1, wherein the actuating element is attached to the wheel fork of the two-wheeled motor vehicle.

### Claim 7 (depends on 1)

The method of claim 1, wherein the two-wheeled motor vehicle includes a motorcycle.

### Claim 8

An apparatus for switching over from a first driver assistance function to a second driver assistance function in a two-wheeled motor vehicle, comprising:
a device configured to perform the following:
detecting a manipulation by a driver of an actuating element;
detecting that an adaptive distance and speed control function is currently active; and
based on the detecting that the adaptive distance control and speed control function is currently active, switching over from the adaptive distance and speed control function to a cruise control function by deactivating the adaptive distance and speed control function and activating the cruise control function;
wherein the switching over is performed only when the manipulation by the driver of the actuating element is an uninterrupted manipulation of the actuating element by the driver over a time interval of predefined length to accomplish the switchover; and
wherein the adaptive distance and speed control function has a lower maximum speed than a maximum speed of the cruise control function.

### Claim 9 (depends on 8)

The apparatus of claim 8, wherein the actuating element is a push-button switch.

### Claim 10 (depends on 9)

The apparatus of claim 9, wherein the push-button-switch is the same push-button switch used for activating the adaptive distance and speed control function.
