<P>PROBLEM TO BE SOLVED: To accurately estimate the state of a friction material of a braking device to control the driving force of a vehicle appropriately on the basis of the estimated state of the friction material. <P>SOLUTION: An ECU executes a program that includes: a step (S100) of calculating regenerative braking power Prg; a step (S102) of calculating a calorific value J; a step (S104) of calculating an abrasion amount AB; a step (S108) of executing driving force restriction control when the abrasion amount AB is more than a threshold AB (0) (YES in S106); a step (S110) of notifying an occupant; and a step (S112) of executing normal driving force control when the abrasion amount AB is the threshold AB (0) or less (NO in S106). <P>COPYRIGHT: (C)2013,JPO&INPIT |
