A METHOD AND SYSTEM FOR PREDICTING A RISK FOR ROLLOVER OF A WORKING MACHINE
First Claim
1. A method for predicting a risk for rollover of a working machine for load transportation, wherein the working machine comprises a load carrying attachment that is liftable in the vertical direction by means of hydraulically controlled pivotal linkage mechanism, the method comprising:
- obtaining ground topographic data of a geographical area located close to the working machine from a ground topographic detection system;
extracting a ground gradient from the ground topographic data;
obtaining weight information of the load being currently transported by means of an on-board load weighting system or by receiving load information originating from the device that loaded the load being currently transported;
obtaining a lift position of the load carrying attachment;
determining a centre of mass of the working machine;
determining a current maximal allowed ground gradient for the working machine based on the weight information, the centre of mass, and the lift position;
predicting a risk for working machine rollover if the working machine approaches a geographical area including a ground gradient exceeding or being close to the current maximal allowed ground gradient for the working machine; and
performing an action to reduce the risk for rollover.

Abstract
A method is provided for predicting a risk for rollover of a working machine for load transportation. The method includes: obtaining ground topographic data of a geographical area located close to the working machine from a ground topographic detection system; extracting a ground gradient from the ground topographic data; obtaining weight information of the load being currently transported by means of an on-board load weighting system or by receiving load information originating from the device that loaded the load being currently transported; determining a current maximal allowed ground gradient for the working machine based on the weight information; and predicting a risk for working machine rollover if the working machine approaches a geographical area including a ground gradient exceeding or being close to the current maximal allowed ground gradient for the working machine.
