Title:
ELECTRIC VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/110802
Kind Code:
A1
Abstract:
An electric vehicle control device which functions as follows. A maximum frequency and a minimum frequency are extracted from frequencies corresponding to respective axle speeds. A first frequency deviation is obtained by subtracting the minimum frequency from the maximum frequency, and this first frequency deviation is input as a primary delay system to obtain a second frequency deviation. Then, an idling detection setting deviation is obtained by subtracting the second frequency deviation from the first frequency deviation, and an idling detection setting value for judging the idling of a wheel at a frequency level is also obtained. The idling frequency deviation and the idling detection setting value are compared to output an idling detection signal, and, based on this idling detection signal, the torque correction amount of an ac motor is computed.
