<p>An ECU (40) calculates the thermal margins Mg_1, Mg_2, Mg_3, Mg_4 of in-wheel motors (20_1, 20_2, 20_3, 20_4) on the basis of the thermal capacities C_1, C_2, C_3, C_4 of the in-wheel motors (20_1, 20_2, 20_3, 20_4), the allowable limit temperatures Tmp_max_1 - Tmp_max_4, and the motor temperatures Tmp_1, Tmp_2, Tmp_3, and Tmp_4 (steps S11-S12). Next, the ECU (40) distributes the total requested torque T_total between the requested torques T_1 - T_4 for each wheel using the percentages of the thermal margins Mg_1 - Mg_4 (S13). The ECU (40) controls the operation of an inverter (25) such that the in-wheel motors (20_1 - 20_4) generate the requested torques T_1 - T_4 for the wheels. Thus, the four in-wheel motors (20) generate uniform amounts of heat.</p> |
