Embodiment Construction

[0022] will now refer to figure 1 The block diagram of the present invention is described in detail. Thus, it concerns a warning system 2 for a vehicle such as a truck, bus or car. The system comprises at least one viewing device 4 having a viewing surface 6 configured to present objects 8 in the vicinity of the vehicle. In one embodiment, the viewing device takes the form of a rearview mirror mounted on the exterior of the vehicle to provide the driver with a reflected image of the viewing surface of the mirror. The invention is also applicable in the case of rearview mirrors installed in vehicles. The viewing surface is preferably a translucent reflective surface.

[0023] In another embodiment, the viewing surface takes the form of a VDU, for example of the LCD type. The warning system further comprises a processing unit 10 configured to receive one or more sensor signals 12 from one or more sensors configured to measure at least objects (such as trucks, cars, buses or ...

Abstract

A warning system (2) for a vehicle, which system comprises at least one viewing device (4) with a viewing surface (6) adapted to presenting objects (8) which are in the vicinity of the vehicle, a processing unit (10) adapted to receiving one or more sensor signals (12) from one or more sensors which are adapted to measuring at least the speed of an object in the vehicle's vicinity, to calculating Deltanu, which is the difference between the respective speeds of said object and the host vehicle, and to comparing Deltanu with at least one threshold value vl. The warning system comprises at least one indicating means (14) situated close to said viewing device (4) and adapted to generating at least one warning indication (16) for presentation on or close to the viewing surface (6) of the viewing device, which warning indication (16) identifies said object and is adapted to being generated in response to a display signal (18) generated by said processing unit (10) if Deltanu exceeds vl.

Description

technical field [0001] The invention relates to a warning system according to the preambles of the independent claims. The invention relates in particular to a warning system adapted to make it easier for a driver to handle overtaking. Background technique [0002] Currently for cars and trucks, existing systems are adapted to monitor the traffic lanes on one or both sides of the vehicle to check if there are any vehicles next to the host vehicle, for example in a dead corner. These systems indicate to the driver the presence of a vehicle in any adjacent traffic lane by producing some form of visual warning near the rearview mirror or on the A-pillar, the part of the car body that sits in front of the front doors and acts as a roof support And secure it on the side of the windshield. Warnings can also take the form of audible warnings, which can be combined with visual warnings. If the driver begins to move into a lane already occupied by vehicles, the warning is progress...
