Problems solved by technology

[0011] Such systems can only effectively reduce fine dust in the environment if they are installed in a very large number of vehicles, and the expense for cleaning the multiple filters and for disposing of the collected dust will be enormous, Especially since relatively coarse dust which is not actually harmful will also be collected and the filter will fill up very quickly

Embodiment Construction

[0035] figure 1 The motor vehicle 1 shown has a scattered light photometer 2 in the wheel housing. The scatter photometer measures the concentration of dust particles present in the wheel well which are resuspended from the road surface 3 or emitted by the corresponding brakes.

[0036] Also refer to figure 2 , during driving operation of the motor vehicle 1 , the dust concentration in the wheel housing is monitored (step S1 ) and estimated (step S2 ) by the scattered light photometer 2 . If the estimated dust concentration in the wheel well exceeds a threshold, and only then, measures are taken to reduce dust resuspension (step S3 ), eg to bind or filter dust and / or aim to reduce the vehicle's travel speed.

Abstract

The disclosure relates to a motor vehicle (1) comprising a dust sensor. The dust sensor is a scattered light photometer (2) according to the disclosure. The scattered light photometer (2) measures the dust load of the air in a region of the motor vehicle in which resuspended or emitted dust has a tendency to occur during travel. In addition, the motor vehicle (1) contains a device for dust reduction, which receives measured data from the scattered light photometer (2), and decides, on the basis of the measured data, whether measures are to be taken against dust resuspension or dust emission. The device takes corresponding measures if the dust load exceeds a threshold value.

Description

technical field [0001] The invention relates to a motor vehicle with a dust sensor and a method for reducing dust resuspension or dust emissions from a motor vehicle according to the preambles of the independent patent claims. Background technique [0002] Traffic-related particulate matter emissions, not caused by exhaust, but by wear of brakes, tyres, clutches, road surfaces, etc. and resuspension of road dust, contribute considerably to air pollution. It is expected that exhaust particulate emissions will decrease due to increasingly strict limit values, but other traffic-related particulate emissions will increase due to greater traffic volumes and may become the focus of future regulations. Based on data from the German Federal Environment Agency, it can be expected that in 2020 exhaust particulate matter emissions will still account for approximately 18% of all traffic-related fine dust emissions, where the term "fine dust" refers to particles with particles smaller th...
