Figure 3 depicts a vehicle wheel control device (4). The control device (4) is configured to determine a first corrective coefficient (alpha 1) of the temperature (T) of the motor from a ratio of an angular speed (omega) of the motor to the supply intensity (i) of the motor depending on the supply voltage (u) of the motor. The control device (4) is configured to determine a second corrective coefficient (alpha 2) of the temperature (T) of the motor from a ratio of the ohmic resistance (R) of the motor to the constant (K) of the motor depending on the temperature (T) of the motor. 图3描绘了车轮控制装置(4)。控制装置(4)被配置成依靠马达的电源电压(u)根据马达的角速度(ω)与马达的电源强度(i)的比率来确定马达的温度(T)的第一校正系数(α1)。控制装置(4)被配置成依靠马达的温度(T)根据马达的欧姆电阻(R)与马达的常数(K)的比率来确定马达的温度(T)的第二校正系数(α2)。
