Abstract
A braking and drive force control apparatus for a vehicle whose wheels are separately driven by electric motors. A controller calculates a drive force or a braking force to be applied to each wheel in accordance with the average sprung displacement and average sprung velocity of the vehicle body which are calculated based on sensed sprung acceleration. By adding the calculated drive force or braking force to the drive force at the time of running, at the time of bouncing of the vehicle body, a downwards force can be generated in the vehicle body which is rising, and an upwards force can be generated in the vehicle body which is descending. By applying an upwards or downwards force to each wheel so as to permit upwards and downwards vibration of the wheels, variations in the ground contact load can be suppressed.
