摘要： A method for controlling an electric machine for driving a motor vehicle. A flux density of at least one magnetic field generated in the electric machine is increased when an announcement signal is present that announces an upcoming acceleration command by the driver, and when a confirmation signal is present that confirms the announced acceleration command, the electric machine is controlled in such a way that the speed and/or torque thereof increases.

摘要： A device/method for the control of a charge operation and the State Of Charge (SOC) of an electrical Energy Storage System (ESS), e.g. a battery, that includes a multitude of cells is provided. The ESS is electrically connected to a propulsion system of a vehicle in order to power an Electric Motor. The method includes charging the ESS from an electrical power source, e.g., the grid, when the vehicle is at standstill, stopping the charging when the SOC level of the ESS is above a maintenance limit for the SOC level of the ESS, monitoring the battery and/or performing a service operation of the ESS after the ESS has been charged to a SOC level above the maintenance limit for the SOC level of the ESS, deliberately discharging the ESS to lower the SOC level. The SOC level of the ESS is reduced to a take-off limit for the SOC level of the ESS which is set in order to allow the vehicle to be controlled to use regenerative braking for charging of the ESS under subsequent driving when the vehicle is restarted and takes off.

摘要： A slip control device for an electric vehicle which errorlessly determines slippage occurrence with only a rotation angle sensor for motor rotation control and perform rapid control to eliminate the slippage, is provided. A threshold calculator 21 calculates a normal angular acceleration of a motor depending on a manipulation amount of an accelerator to obtain a threshold, and an angular acceleration calculator 22 differentiates a detection value from a rotation angle sensor 3a twice to calculate an angular acceleration. A slip determination 23 determines whether a wheel 7 driven by a motor 3 has slipped, and a torque limitation 25 limits a torque when determining a slippage. The determination 23 compares the calculated acceleration to the threshold, counts a number of times it is consecutively determined that the calculated acceleration exceeds the threshold, and determines a slippage if the number of times has reached a set value.

摘要： An engine start using an electric motor during a vehicle travel is performed by increasing an output torque of the electric motor in a slip state where a second frictional engagement element 3 connecting the electric motor 1 and a driving wheel slips. A controller determines a requested acceleration amount from a depression amount of an accelerator pedal. When the requested acceleration amount is significant, a different torque increment characteristic is applied, compared to a case where the requested acceleration amount is not significant. Thus, the internal combustion engine starts in a high response depending on the requested acceleration amount input by the driver, thereby improving a vehicle acceleration response.
