1. A method of preventing a mine vehicle from colliding, the mine vehicle comprising at least:
- a movable carrier that is driven in a first movement direction and in a second movement direction, at least one scanner, and a control system including at least a first control unit arranged on the carrier;
the method comprising;
determining for the mine vehicle at least one safe area provided within an area between minimum distances and maximum distances determined with respect to the vehicle;
scanning the environment in front of the vehicle when driving the vehicle in one movement direction;
carrying out a first collision examination wherein the safe area in front of the vehicle is monitored, and issuing a collision warning message if an obstacle is detected within the safe area,determining also at least one sideward safe area for the vehicle, determining an obstacle-free route on the basis of the forward scanning results, and determining points in a sideward direction of the vehicle to restrict the route;
forming memory points on the basis of coordinates of the points restricting the route, and storing the memory points in the control system,and carrying out a second collision examination wherein at least one sideward safe area of the vehicle is monitored, and issuing a collision warning message if even one of the memory points resides within the safe area being monitored.

Abstract
A mine vehicle and a method of preventing a mine vehicle from colliding. The mine vehicle (1) includes at least one scanner (13, 14) to scan the environment in front of the vehicle. On the basis of the scanning, an obstacle-free route is determined whose outermost points in a sideward direction are stored as memory points (21). At least one sideward safe area (15b) has been predetermined around the vehicle (1). A control system checks that no memory point (21) resides within the safe area (15b).
