Abstract

A driver assistance system for motor vehicles, including at least one sensor for detecting object properties of objects which are located in the surroundings of the motor vehicle; a first interface; an output unit for transmitting the object properties to a user; and a control unit. The sensor transmits the object properties in a form of a first signal to the first interface. The first interface transmits the object properties, received in the form of the first signal, to the control unit in the form of a second signal, the control unit being configured to forward the object properties, received in the form of a second signal, to the output unit and to control the output of the object properties by the output unit.

Claims

1. A driver assistance system for a motor vehicle, comprising:

at least one sensor adapted to be physically joined to a body of the motor vehicle and electrically connected to a battery of the motor vehicle to detect object properties of objects which are located in surroundings of the motor vehicle;

an interface;

an output unit to transmit the object properties to a user; and

a control unit;

wherein;

at least one of the control unit and the output unit is housed in a device capable of being carried on a person of a driver into and out of the motor vehicle,

the sensor transmits the object properties to the interface in the form of a first signal,

the interface transmits the object properties, received in the form of the first signal, to the control unit in the form of a second signal,

the control unit is configured to forward the object properties, received in the form of the second signal, to the output unit and to control the output of the object properties by the output unit,

the control unit is a processor of a smartphone, on which an application software (APP) is executed, the control unit being configured to process the object properties before forwarding to the output unit, as a function of inputs of a user received via an input mask of the APP,

the control unit monitors the object properties for predetermined properties with respect to at least one of;

(i) a course of the motor vehicle, and (ii) a speed of the motor vehicle, for imminent collisions or predetermined safety distances, and the predetermined properties being identified through comparison of one or multiple of the object properties with threshold values of the object properties stored in a memory of the control unit, and

the control unit outputs to the user at least one of;

(i) a visual warning, and (ii) an acoustic warning, via the output unit if a predetermined property of the object properties has been ascertained.

2. The driver assistance system as recited in claim 1, wherein the processing of the object properties includes that the object properties are processed as a function of data detected by at least one sensor of the mobile unit.

3. The driver assistance system as recited in claim 1, wherein the processing of the object properties includes that at least one of:

(i) the object properties are incorporated into a graphic or a diagram, and (ii) the object properties are superimposed with a camera image from a camera of the mobile unit.

4. The driver assistance system as recited in claim 1, wherein the control unit is a processor of a navigation system which is installed in the motor vehicle.

5. The driver assistance system as recited in claim 1, wherein the output unit is a display of the smartphone, the object properties being transmitted to the user at least one of:

(i) in the form of a graphic output of the APP, and (ii) acoustically.

6. The driver assistance system as recited in claim 1, wherein the output unit is part of a GPS navigation device of the motor vehicle, the object properties being transmitted to the user via the GPS navigation device of the motor vehicle in at least one of:

(i) visual form, and (ii) acoustic form.

7. The driver assistance system as recited in claim 1, wherein the output unit is a projector which transmits the object properties to the user in visual form, the visual transmission being carried out in the form of a projection onto a windshield of the motor vehicle.

8. The driver assistance system as recited in claim 1, wherein the first signal is a CAN signal as is also used in a CAN (Controlled Area Network).

9. The driver assistance system as recited in claim 1, wherein the second signal is a Bluetooth signal, the interface converting the first signal into a Bluetooth signal.

10. The driver assistance system as recited in claim 1, wherein the second signal is a WLAN signal, the interface converting the first signal into a WLAN signal.

11. The driver assistance system as recited in claim 1, wherein the object properties are associated with respective values, wherein the output unit is a display of the smartphone and the object properties of different objects are grouped in accordance with the respective values, different marking intensities being assigned to the groups in the output unit.

12. The driver assistance system as recited in claim 1, wherein the object property is a differential speed of the motor vehicle, the differential speeds of the objects being color coded in the output unit.

13. The driver assistance system as recited in claim 1, further comprising:

an additional output unit, the control unit forwarding the output of the object properties to the output unit and to the additional output unit.

14. The driver assistance system as recited in claim 13, wherein the control unit is a processor of a smartphone, on which an application software (APP) is executed, the output unit being the display of the smartphone, the additional output unit being the display of a navigation device, and the forwarding of the object properties to the additional output unit being carried out by a mirroring function of the APP executed on the processor of the smartphone.
