Method and device for detecting a collision between a vehicle and an object using a mobile user terminal which is able to be coupled to the vehicle
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.
1. 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, 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.
2. The method as recited in claim 1 , 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.
3. The method as recited in claim 1 , 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.
4. The method as recited in claim 1 , 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.
5. The method as recited in claim 4 , wherein the collision signal is ascertained based on the user terminal signal and the driving state signal.
6. The method as recited in claim 4 , wherein a steering angle of the vehicle is utilized in order to determine whether the forward collision warning signal is to be suppressed.
7. The method as recited in claim 4 , 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.
8. 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, 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.
9. 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,
the device comprising:
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 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, 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.
