Abstract:
An object of the present invention is to provide a control apparatus for an electric vehicle capable of preventing the vehicle from being destabilized because a rear wheel is locked first or drivability from reducing because a front wheel is locked early. A control apparatus includes a regenerative braking force calculation portion configured to calculate a regenerative braking force to be generated on each of a front motor and a rear motor based on a request braking force requested to an electric vehicle, a power limit portion configured to reduce the regenerative braking force based on a power limit on a power source, and a frictional braking force output portion configured to output an instruction for generating a frictional braking force according to a regenerative braking force reduction amount, which is an amount of a reduction in the regenerative braking force by the power limit portion, to a brake apparatus.
