Gritting method, Gritting control arrangement and Gritting Vehicle

摘要

Methods and systems for controlled gritting of routes, e.g. roads, are disclosed. A gritting vehicle (3) has a continuously-operating position detection arrangement e.g. GPS and has an on-board information processor (MDT) in which route data such as forecast thermal map data are stored. The stored data can be transmitted to the vehicle (3) from a control station processor via a radio link. Real-time positional data are compared with the route data in the vehicle's processor and generate gritting instructions to control whether and how much grit is deposited at a given location. Positional and gritting status information may be transmitted back to the control station (1) progressively for recording. On-board sensors (S) may be used to supplement forecast data.
