摘要

PPROBLEM TO BE SOLVED: To provide a control device for an AC motor-driven vehicle, detecting the temperature of a motor near an inverter, and preventing a temperature rise of the inverter based on the detected temperature in either case of two-wheel drive and four-wheel drive. PSOLUTION: This control device for the AC motor-driven vehicle having a power generator 7, the inverter converting power generated by the power generator 7, and the AC motor 4 supplied with the power converted by the inverter, and traveling in either of a four-wheel drive mode and a two-wheel drive mode includes a 4WD controller 8 suppressing the rise in the temperature affecting at least the inverter by restricting the drive of an engine in the two-wheel drive mode and restricting torque output by the AC motor 4 in the four-wheel drive mode when the temperature detected by a temperature sensor 20 detecting the temperature of the AC motor 4 reaches a prescribed threshold value in either case of four-wheel drive mode traveling and two-wheel drive mode traveling.

要解决的问题:提供一种用于交流电动机驱动的车辆的控制装置,该电动机在逆变器附近检测电动机的温度,并根据检测到的温度在两种情况下均防止逆变器温度升高,轮驱动和四轮驱动。

解决方案:该控制装置用于交流电动机驱动的车辆,其具有发电机7,将由发电机7产生的电力转换成逆变器,以及由逆变器转换后的电力被供给并在任一个中行驶的AC电动机4。在四轮驱动模式和两轮驱动模式中,“四轮驱动”控制器8包括四轮驱动控制器8,其通过在两轮驱动模式下限制发动机的驱动并限制由电动机驱动的扭矩来抑制至少影响逆变器的温度升高。当在四轮驱动模式行进和两轮驱动模式行进的任何一种情况下,当由温度传感器20检测到交流电动机4的温度的温度达到规定的阈值时,交流电动机4处于四轮驱动模式。
