    摘要： A field winding type rotary electric machine includes a motor generator; a field current detection unit; a field current control unit which controls a field current; a field current limiting determination section which calculates a field current integration value and determines whether or not the field current integration value reaches a predetermined field current integration threshold value; and a field current limiting command section which, when it is determined that the field current integration value reaches the predetermined field current integration threshold value, outputs a command which sets the field current to be lower than or equal to a predetermined field current limiting value to the field current control unit during a predetermined limiting time, and outputs a command which changes the predetermined limiting time depending on the field current. Accordingly, a temperature rise of the machine is suppressed and limiting of the field current can be released as needed.

    摘要： A radar device capable of detecting a target object by itself only in a range required by a vehicle control system by changing the detection angle depending on the distance without changing the hardware structure is provided. The radar device includes transmitting means for transmitting an electromagnetic wave as a transmission signal, receiving means for receiving the electromagnetic wave reflected from the target object as a reception signal, and signal processing means for detecting a target object existing around the vehicle from the transmission signal and the reception signal, and calculating the relative position and the relative speed between the object and the vehicle. The detection angle is changed depending on the distance for measurement, so that the target object is detected only in a region necessary in operating the vehicle control system.
