Problems solved by technology

However, this still does not solve the following key problem: In many blind spot accidents, the person (target) in the blind spot does not know that he / she cannot be seen by the driver (host)
[0011] On the downside, however, the equipment with said sensors and indicators is very expensive and, since all necessary parts of the system need to be electrically connected, it is generally not possible to retrofit existing systems with said systems

Embodiment Construction

[0067] figure 1 A schematic top view of a vehicle including a cab 12 and a trailer 14 is shown. Typically, the driver is able to directly observe his surroundings through the windshield and side windows of the cab 12 . Regions 16 , 18 and 20 are therefore directly visible to the driver. The areas indicated by reference numerals 22 and 24 are also visible to the driver indirectly through a rearview mirror (not shown). However, there are still a number of blind spot areas 1 to 8 which cannot be directly or indirectly observed by the driver.

[0068] Although additional mirrors can expand the driver's field of vision, this solution can have adverse aerodynamic effects and also increases the complexity of the driver interface. Additionally, these mirrors are difficult to adjust, and the wide-angle mirrors only provide a distorted view of surrounding traffic.

[0069] Another solution to this problem could be an active system that detects objects in the blind spot and warns th...

Abstract

The present invention discloses a blind spot warning device attachable to a host vehicle's (10) exterior comprising a warning (34) indicating at least one blind spot (1 - 8) of the host vehicle (10) to a target object (30) being outside the host vehicle (10), wherein the warning (34) is only perceptible for the target object (30) in dependence on the target object's relative position to the host vehicle (10). Further, a blind spot detection system is disclosed and a vehicle comprising such a blind spot warning device and / or such a blind spot detection system is disclosed.

Description

technical field [0001] The invention relates to a blind spot warning device and a blind spot warning system for a host vehicle according to the preambles of claims 1, 29, 31 and 33, and to a vehicle comprising said blind spot warning device and blind spot warning system. Background technique [0002] Many traffic accidents are related to the driver's limited field of vision and the so-called blind spot area around the vehicle. For example, with heavy trucks there are large blind spots all around the vehicle, but so are other vehicles such as cars, buses or construction equipment. The following are examples of traffic situations where a truck's limited field of view could lead to a dangerous situation: [0003] ● lane changes and turns towards the passenger side, [0004] Starting from a standstill at a zebra crossing and other situations in which road users may be in front of the vehicle, [0005] ●For example, back-up situations when queuing up to the pier. [0006] Alt...
