A method for detecting objects in the surroundings of a vehicle. The method includes reading in a first image, of a vehicle camera, which represents the surroundings taken using a first exposure time and reading in a second image of the vehicle camera, which was taken after the first image and using a second exposure time, the second exposure time differing from the first exposure time, and extracting an image detail from the second image, the image detail representing a smaller area of the surroundings than the first image. During the extracting, a position of the image detail in the second image is determined based on at least one parameter which represents information on travel of the vehicle and/or a position of an infrastructure measure in front of the vehicle and/or which is independent of a moving object that was detected in a preceding step in the image detail.

A radiator module for commercial motor vehicles, in particular for agricultural tractors, has a support plate (7) fixed to the chassis and at least one coolant radiator (10) fixed to the support plate. The radiator has a radiator block (17) and two coolant tanks (19, 20) oriented at opposite ends of the block with one tank (20) adjacent the support plate (7) and one (19) spaced away form the support plate.

In order to increase the cooling performance of the radiator module (6) despite keeping the installation space above the support plate (7) constant it is proposed that the coolant tank near the plate (20) is constructed from two mutually complementing tank parts (26, 28). The first tank part (26) is assigned to the radiator block (17) and has an encircling flange (25) for pressure sealed attachment of the coolant radiator (10) on the support plate (7). A second tank part (28) is assigned to the support plate (7).

By dividing the coolant tank (20) into two parts, one on the radiator block (17) and one on the support plate (7) the effective heat sink area of the coolant radiator (10) can be substantially increased. On the one hand the enlargement is due to the fact that the flange (25) encircling the first tank part also serves to attach the coolant radiator on the support plate and in this region an assembly gap is therefore left between these components. On the other hand the enlargement is due to the fact that by moving part of the coolant tank under the surface of the support plate, the overall height of the coolant radiator is increased accordingly.

The data symbols (12) each have at least two bits (18) of the digital signal (10), and the code space (40) comprises code symbols (16) of two groups (38, 39).
