- a recognition device detects obstacles in the lateral environment of the motor vehicle. If the detection device detects an obstacle, calculates a calculation means based on the steering angle and the vehicle speed of the vehicle ahead of whether a collision with the obstacle threatens, and generates a warning signal for the driver in case of collision.
- a method for warning the driver of a vehicle in front of a vehicle driving on the instantaneous track is known.
- the traffic environment is monitored in front of the vehicle by means of a radar device for the presence of a preceding vehicle and the distance of the own vehicle to a detected vehicle ahead, and determines its relative speed.
- a safety distance between the two vehicles is calculated, which is then compared with the measured distance. If the measured distance is less than the safety margin, a warning signal is generated and the risk of collision is displayed on an optical display panel.
- the surroundings detection is also extended to the respective rear space of adjacent lanes, so that even in the run-up to a planned lane change the expected accident risk can be determined.
- DE 195 07 957 Cl discloses a vehicle that is equipped with a system for sleep alarm.

- a reliable detection of the roadway edge can be done either via contrast images of a camera or via imaging distance measurements, for example via radar scanner. These sensors scan the edge development or edge planting and thus limit the paved road edges.
- recognition of a lane change takes place when there is a difference between the signals which are directed by the sensors which are aligned in the same vehicle transverse direction.
- At least one infrared sensor is mounted on at least one front and / or at least one rear bumper, wherein at least each attached infrared sensors on each individual bumper has at least two different Abstrahlöff- angle for scanning a relevant area of the road surface and the road edge and of a permanent scan of the relevant area of the road surface and the road edge is performed to all infrared sensors, wherein the signals detected by the individual infrared sensors are related to each other.

- detection of a lane change takes place when a difference between the space area of the front right vehicle corner and the rear right vehicle corner and / or the front left vehicle corner and the rear left vehicle corner is detected, as determined by the infrared sensors indicates a change in the direction of travel reflects.
- the driver which can be activated by the driver is checked and when the signal transmitter is deactivated, an optical, acoustic or haptic warning signal is emitted to the driver via an unintentional lane change in order to warn the driver of an unintended lane change.
- an optical, acoustic or haptic warning signal is emitted to the driver via an unintentional lane change in order to warn the driver of an unintended lane change.
- a warning signal can be issued from a speed of 70 km / h, in order to warn the driver of possible collisions or accident hazards that can occur due to an unintended lane change.
- 1 shows an arrangement of sensors for scanning the road surface.
- Fig. 2 the detection of a lane change on marked and unmarked lane.
- the road recognition sensor elements 10a and 10b, 12a and 12b are installed, for example, as infrared sensor elements on the front and / or rear bumper 14, which cover both the road surface 22 and the roadside 20 at all four vehicle corners (VL, VR, VR). HL and HR).
- the detected signals are related.
- the road recognition sensors 10 and 12 each have two distinct emission characteristics with different angles of departure.
- the first emission direction 16a / 16b lies on both sides transversely to the vehicle longitudinal direction, thus in the vehicle transverse direction and the second 18a / 18b in the vehicle longitudinal direction.
- the beam with a smaller opening angle for scanning the roadway surface 22 is denoted by 18a or 18b
- the beam with a larger opening angle for scanning the roadside is denoted by 16a or 16b in FIG.

It is envisaged that the individual elements are interconnected to compensated element group. Sensors are used for the mentioned vehicle peripheral monitoring, which scan or scan areas of the environment from 0.5 m to 150 m.
- the regions to be scanned are determined, on the one hand, by the respective aperture angle of the respective transmitting diode of the infrared sensor element and, on the other hand, by the geometrical positioning of the infrared sensor elements relative to one another on the respective shock absorber. If radiation of the same intensity is applied to the two infrared sensor elements which are located at the front right corner, the resulting output signal of the element group is zero. By contrast, different radiation intensities on both sensitive infrared sensor elements lead to an output signal of the respective element group, which corresponds to the difference between the output signals of the individual sensor elements.
