A system of electric batteries includes a plurality of batteries (HVB, HVB, HVB) connected to each other by two polarities. Each battery has at least two relays (RN, RP, RA) for the connecting of poles of the battery to the two polarities. The system includes a secondary power supply to provide an activation energy to the relays. The system includes means of supervision to control the relays (RN, RP, RA) in a staggered manner so that each activation of a relay follows a previous activation by at least a predetermined time period (DT).

System of batteries and method of controlling this system

In order to control the disengagement limit position of a movable dog relative to a fixed dog of a motor vehicle transmission, the following steps are implemented: acquiring position values of the movable dog; detecting an abutment position of the movable dog against the fixed dog for a predefined period; and calculating the limit position from the position value of the movable dog in abutment against the fixed dog.
