PURPOSE:To improve the regenerating rate of electric power into power supply by increasing the regenerative braking torque of a motor within a range, wherein there is no effect on brake feeling, in a dedicated electric regenerative braking controller for an electric automobile. CONSTITUTION:When a first temporary target-torque value T* (S4) corresponding to brake pressure P (S3) is larger than the maximum torque value TMAX (S5) corresponding to the present value (S3) of the number of revolution of a motor N (S6), the TMAX is made to be a second temporary target torque value T** (S11). When the reducing speed of a vehicle is increased slightly largely when vehicle is actually braked and there might be the effect on brake feeling (S13-15), the previous final target torque value T*** (i-1) is made to be the final target torque value at this time T*** (i) (S17). When there might no such effect, the second temporary target torque value T**is made to be the final objective torque value at this time T*** (i). |
