REGENERATIVE BRAKING FORCE CONTROLLER FOR ELECTRIC VEHICLE

PROBLEM TO BE SOLVED: To appropriately control a regenerative braking force in an electric vehicle while suppressing increases of a cost and time. SOLUTION: A regenerative braking force controller includes a regenerative braking executing means 42 and an additional regenerative braking force calculating means 41. The regenerative braking executing means operates a motor generator 12 as a generator, and executes regenerative braking setting a usual regenerative braking force Tb as a target regenerative braking force TcB, when an accelerator pedal 16 is not trod. The additional regenerative braking force calculating means calculates an additional regenerative braking force Tbh according to a driving force value F showing a driving force which is produced by gravity exerting on the electric vehicle 12. The regenerative braking executing means 42 is constituted to execute the regenerative braking, obtaining the target regenerative braking force TcB by adding the additional regenerative braking force Tbh to the usual regenerative braking force Tb.
