• determine whether an actual state, which is related to the connection and the disconnection of the clutch, and the assumed state match each other in accordance with a temporal change in the secondary information;
• cancel a hill-hold function for retaining a brake force generated in the vehicle on an inclined road surface in accordance with both the primary information and secondary information when the actual state and the assumed state match;
• and
• cancel the hill-hold function in accordance with the primary information but not the secondary information when the actual state and the assumed state do not match each other.
