PROBLEM TO BE SOLVED: To transfer regenerative braking to frictional braking by surely terminating the regenerative braking in a low vehicle speed region, while preventing a regenerative braking termination control while vehicle speed is decreasing from becoming nonsmooth by fluctuation of driving wheel speed during shifting. SOLUTION: A regenerative braking force limit value TmLmtde is determined based on driving wheel speed Vwde and a regenerative braking force limit value TmLmtdn is determined based on driven wheel speed Vwdn, during the shifts of t1 to t2 accompanying speed reduction. An absolute value lowering rate of the TmLmtdn is made larger than that of the TmLmtde in relation to lowering of vehicle speed. A smaller absolute value of the TmLmtde and TmLmtdn is contributed to a limit of regenerative braking force. COPYRIGHT: (C)2010,JPO&INPIT
