Abstract

A driver assistance system for intervening in the control of at least one of a drive system, a controller, or signaling devices of a motor vehicle includes: a radar control unit having a radar sensor; and a mobile device having a video sensor for ascertaining surroundings information, the mobile device being a mobile phone or a smart phone, for example. In this case, the mobile device transmits the ascertained surroundings information to the radar control unit via a first wireless connection.

Claims

1. A driver assistance system for intervening in the control of at least one of a drive system, a controller and signaling devices of a motor vehicle, comprising:

a radar control unit having a radar sensor; and

a mobile device having a video sensor ascertaining surroundings information, wherein the mobile device transmits the ascertained surroundings information to the radar control unit via a first wireless connection.

2. The driver assistance system as recited in claim 1, wherein the radar control unit is connected to at least one of an engine controller and an electronic stability program.

3. The driver assistance system as recited in claim 2, wherein the radar control unit has a sensor data fusion unit for processing vehicle information and the ascertained surroundings information of the mobile device.

4. The driver assistance system as recited in claim 3, wherein the connection between the radar control unit and the mobile device takes place via Bluetooth.

5. The driver assistance system as recited in claim 3, wherein the first wireless connection enables a gross data rate of at least 1 Mbit/s.

6. The driver assistance system as recited in claim 3, further comprising:

a head unit control unit connected to at least one of the electronic stability program and the engine controller.

7. The driver assistance system as recited in claim 6, wherein the head unit control unit is connected to the radar control unit via a second wireless connection.

8. The driver assistance system as recited in claim 7, wherein the second connection between the radar control unit and the head unit control unit takes place via Bluetooth.

9. The driver assistance system as recited in claim 7, wherein vehicle-internal information from sensors of at least one of an ABS system, a TCS system, an electronic stability program, a chassis control system, a restraint system, and an engine control system is incorporated for ascertaining the vehicle information.

10. A method for operating a driver assistance system for intervening in the control of at least one of a drive system, a controller and signaling devices of a motor vehicle, the driver assistance system including a radar control unit having a radar sensor, and a mobile device having a video sensor, the method comprising:

mounting the mobile device on the motor vehicle;

establishing a first wireless connection between the mobile device and a radar control unit;

carrying out a calibration between the mobile device and the radar control unit;

detecting data regarding the vehicle surroundings of the motor vehicle via the video sensor of the mobile device;

ascertaining, by the radar control unit, data regarding vehicle information of the motor vehicle;

transmitting the detected data regarding the vehicle surroundings of the motor vehicle to the radar control unit via the first wireless connection;

fusing, by the radar control unit, the data regarding vehicle information and the data regarding the vehicle surroundings according to an accident computation algorithm;

relaying, with the aid of the radar control unit, the control instructions to at least one of the drive system, the controller and the signaling devices of the motor vehicle; and

initiating an autonomous braking action in the event of a recognized critical traffic situation.

11. The method as recited in claim 10, wherein the radar control unit additionally receives and fuses vehicle-internal information from sensors of at least one of an ABS system, a TCS system, an electronic stability program, a chassis control system, a restraint system, and an engine control system.

12. The method as recited in claim 11, wherein the radar control unit additionally receives and fuses vehicle-external information of other road users which are present in the surroundings of the motor vehicle from at least one of vehicle-to-vehicle communication interfaces and vehicle-to-x communication interfaces.
