Abstract
A method for assessing reliability of a brake assembly of a vehicle. The brake assembly comprises brake system, nominal automation system and safety system. The brake system is adapted to receive a brake request individually from each one of the nominal automation system and the safety system and in response, initiate a braking operation. The method comprises determining an actual braking operation density, the actual braking operation density determined on the basis of at least a subset of occurrences per unit time when a braking operation is initiated by the brake system; in response to detecting that the actual braking operation density is lower than a braking operation reference density, issuing a brake request from the safety system; detecting a response of the brake system to the signal issued from the safety system, and on the basis of at least the detected response, assessing the reliability of the brake assembly.
