#CMT# #/CMT# The method involves operating an electromotor (3) in a delta connection. A power demand on the electromotor is monitored. An operation of the electromotor is changed from the delta connection to a star connection when the power demand on the electromotor falls below a predetermined threshold value. A value for the power demand is obtained from a position of pedals, a rotation speed of a wheel of a vehicle and a current value that is measured in a supply conduit of the electromotor, where the electromotor is designed as a three-phase alternating current asynchronous motor. #CMT# : #/CMT# An independent claim is also included for a vehicle comprising a control device operating an electromotor a delta connection. #CMT#USE : #/CMT# Method for operating of a vehicle i.e. electric car. #CMT#ADVANTAGE : #/CMT# The operation of the electromotor is changed from the delta connection to the star connection when the power demand on the electromotor falls below the predetermined threshold value, thus reducing power consumption of the electromotor to drive the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic diagram of a powertrain of a vehicle.'(Drawing includes non-English language text)' 1 : Internal combustion engine 2 : Starter clutch 3 : Electromotor 4 : Recuperation clutch 5 : Automatic transmission. |
