Claim:
1. A slip control device, provided in an electric automobile including a plurality of electric motor units individually driving a plurality of associated drive wheels including left and right drive wheels, for slip-controlling the electric automobile, the slip control device comprising: a threshold calculation module configured to calculate a normal angular acceleration of a first motor unit as a function of a manipulation amount of an accelerator to calculate a threshold for slip determination, on the basis of the calculated normal angular acceleration; an angular acceleration calculation module configured to calculate an angular acceleration of the first motor unit on the basis of a detection value from a rotation speed detection device that detects a rotation speed of the first motor unit; a slip determination module configured to determine whether a first drive wheel driven by the first motor unit has slipped, the slip determination module including: a torque limiting module configured to limit a torque developed by the first motor unit, if the slip determination module determines that the slippage has occurred, the torque limiting module including:
