Abstract

In a method for detecting a collision between a vehicle and an object using a mobile user terminal which is able to be coupled to the vehicle, a user terminal signal for detecting the object is read in, which user terminal signal represents a signal which is provided by an image sensor of the user terminal; a driving state signal is read in to detect a driving state of the vehicle, which driving state signal represents a measured variable output by a vehicle sensor via an interface between the user terminal and the vehicle and/or output by an acceleration sensor of the user terminal; and a collision signal is ascertained to indicate an imminent collision between the vehicle and the object, based on the user terminal signal and the driving state signal.

10 . A method for detecting an imminent collision between a vehicle and an object using a mobile user terminal which is able to be coupled to the vehicle, the method comprising:
reading in a user terminal signal for detecting the object, the user terminal signal representing a signal provided by an image sensor of the user terminal; reading in a driving state signal for detecting a driving state of the vehicle, the driving state signal representing a measured variable which is output by at least one of (i) a vehicle sensor via an interface between the user terminal and the vehicle and (ii) an acceleration sensor of the user terminal; ascertaining, based on the user terminal signal and the driving state signal, a collision signal for indicating an imminent collision between the vehicle and the object; outputting, via the user terminal, a collision warning signal based on the collision signal; and reading in a telephoning signal, which represents an active telephone connection of the user terminal, wherein the timing of the outputting of the collision warning signal is carried out earlier in the presence of the telephoning signal in comparison to the timing of the outputting of the collision warning signal in the absence of the telephoning signal.

11 . A method for detecting an imminent collision between a vehicle and an object using a mobile user terminal which is able to be coupled to the vehicle, the method comprising:
reading in a user terminal signal for detecting the object, the user terminal signal representing a signal provided by an image sensor of the user terminal; reading in a driving state signal for detecting a driving state of the vehicle, the driving state signal representing a measured variable which is output by at least one of (i) a vehicle sensor via an interface between the user terminal and the vehicle and (ii) an acceleration sensor of the user terminal; ascertaining, based on the user terminal signal and the driving state signal, a collision signal for indicating an imminent collision between the vehicle and the object; reading in an image signal in order to detect a state of a driver, the image signal representing a signal provided by a further image sensor of the user terminal; and outputting, via the user terminal, a collision warning signal as a function of the collision signal and the image signal.

12 . A method for detecting an imminent collision between a vehicle and an object situated in front of the vehicle using a mobile user terminal which is able to be coupled to the vehicle, the method comprising:
reading in a user terminal signal for detecting the object, the user terminal signal representing a signal provided by an image sensor of the user terminal; ascertaining, based on at least the user terminal signal, a collision signal for indicating an imminent collision between the vehicle and the object; and outputting, via the user terminal, a forward collision warning signal as a function of at least the collision signal and a detected driver action, wherein outputting of the forward collision warning signal is suppressed when the detected driver action is determined to be sufficient to avoid a collision.

13 . The method as recited in claim 10 , wherein in the step of ascertaining the collision signal, a collision danger is ascertained using the user terminal signal and plausibilized with the aid of the driving state signal in order to ascertain the collision signal.

14 . The method as recited in claim 11 , wherein in the step of ascertaining the collision signal, a collision danger is ascertained using the user terminal signal and plausibilized with the aid of the driving state signal in order to ascertain the collision signal.

15 . The method as recited in claim 12 , wherein in the step of ascertaining the collision signal, a collision danger is ascertained using the user terminal signal and plausibilized with the aid of a driving state signal in order to ascertain the collision signal.

16 . The method as recited in claim 10 , further comprising:
supplying, based on the collision signal, an activation signal to the interface between the user terminal and the vehicle in order to activate a vehicle safety system.

17 . The method as recited in claim 11 , further comprising:
supplying, based on the collision signal, an activation signal to the interface between the user terminal and the vehicle in order to activate a vehicle safety system.

18 . The method as recited in claim 12 , further comprising:
supplying, based on the collision signal, an activation signal to an interface between the user terminal and the vehicle in order to activate a vehicle safety system.

19 . The method as recited in claim 12 , wherein the mobile user terminal utilizes at least one of 6-D and 9-D acceleration sensors integrated into the mobile user terminal to detect a deceleration of the vehicle associated with a driver braking action in order to determine whether the forward collision warning signal is to be suppressed.

20 . The method as recited in claim 12 , further comprising:
reading in a driving state signal for detecting a driving state of the vehicle, the driving state signal representing a measured variable which is output by at least one of (i) a vehicle sensor via an interface between the user terminal and the vehicle and (ii) an acceleration sensor of the user terminal.

21 . The method as recited in claim 20 , wherein the collision signal is ascertained based on the user terminal signal and the driving state signal.

22 . The method as recited in claim 20 , wherein a steering angle of the vehicle is utilized in order to determine whether the forward collision warning signal is to be suppressed.

23 . The method as recited in claim 20 , wherein the forward collision warning signal is outputted as a function of at least the collision signal, a steering angle of the vehicle, and a detected lane marking.

24 . A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, perform a method for detecting an imminent collision between a vehicle and an object situated in front of the vehicle using a mobile user terminal which is able to be coupled to the vehicle, the method comprising:
reading in a user terminal signal for detecting the object, the user terminal signal representing a signal provided by an image sensor of the user terminal; ascertaining, based on at least the user terminal signal, a collision signal for indicating an imminent collision between the vehicle and the object; and outputting, via the user terminal, a forward collision warning signal as a function of at least the collision signal and a detected driver action, wherein outputting of the forward collision warning signal is suppressed when the detected driver action is determined to be sufficient to avoid a collision.

25 . A device for detecting a collision between a vehicle and an object, the device being a part of a mobile user terminal configured to be selectively coupled to the vehicle,

a read-in unit configured to read in a user terminal signal for detecting the object, the user terminal signal representing a signal provided by an image sensor of the mobile user terminal; and
a control unit configured to:
ascertain, based on at least the user terminal signal, a collision signal for indicating an imminent collision between the vehicle and the object; and
output a forward collision warning signal as a function of at least the collision
