<P>PROBLEM TO BE SOLVED: To reduce variation in the total braking torque even if a friction torque of driven wheels varies during braking by regenerative cooperation control. <P>SOLUTION: A controller of an electric vehicle includes: a regenerative and friction torque calculation part B1 by which a regenerative torque command Fm<SP POS="POST">*</SP>by regenerative brakes of right and left front wheels, and a friction torque command Fb<SP POS="POST">*</SP>by respective friction brakes of the right and left front wheels and right and left rear wheels are calculated against the total braking torque command Ftotal<SP POS="POST">*</SP>based on a brake operation; a friction torque execution value calculation part B2 by which a friction torque execution value Fb, which is a friction torque value executed by the respective friction brakes of the right and left front wheels and the right and left rear wheels, is estimated and calculated; a regenerative torque correction value/friction torque correction value calculation part B5 by which a deviation between the friction torque command Fb<SP POS="POST">*</SP>and the friction torque execution value Fb is calculated for a portion of each wheel of the right and left front wheels and the right and left rear wheels, and the total friction torque deviation obtained by adding these deviations is outputted as the regenerative torque correction value Fm_add added to the regenerative torque command Fm<SP POS="POST">*</SP>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
