Abstract
A particulate collecting device (100) attachable to a vehicle for collecting or capturing particulates that are released from a tyre or a wheel (W) of the vehicle through wear on or against a driving surface (S) when the vehicle is driven on the driving surface. The device comprises an electrostatic filter unit (110) mountable in an operative position in close proximity to the tyre or the wheel of the vehicle for receiving a flow of particulates (FI) from a contact point (CP) between the tyre or wheel and the driving surface. The filter unit (110) is configured to collect or capture the particulates in the flow by electrostatic attraction.

1-49. (canceled)
A particulate collecting device configured to attach to a vehicle and collect or capture particulates that are released from a tyre or a wheel of the vehicle through wear on or against a driving surface when the vehicle is driven on the driving surface, comprising:
- an electrostatic filter unit for collecting or capturing the particulates in a flow by electrostatic attraction, the electrostatic filter unit mountable in an operative position in close proximity to the tyre of the vehicle for receiving a flow of particulates from a contact point between the tyre or wheel and the driving surface, the filter unit comprising one or more electrostatically chargeable collector plates to attract charged particulates in the flow when the collector plates are charged.
A method of collecting or capturing particulates that are released from a tyre or a wheel of a vehicle through wear on or against a driving surface when the vehicle is moving using a particulate collecting device according to claim 1, comprising:
- receiving, at the electrostatic filter unit mounted in the operative position, an airflow around the tyre or wheel containing said particulates from a contact point between the tyre or wheel and the driving surface entrained therein;
- and
- collecting or capturing the particulates in the flow by electrostatic attraction by charging at least one of the one or more collectors electrodes of the electrostatic filter unit to attract the particulates in the flow to the at least one collector electrode;
- and, optionally or preferably, without pre-charging the particulates.
