A method for controlling a hybrid starter and generator (HSG) is applied to an eco-friendly vehicle. The method includes HSG torque-output limiting control, and in particular, the HSG torque-output limiting control is divided into an HSG regeneration mode and an HSG driving mode in which output limitation of the HSG 3 is performed after torque limitation of the HSG 3. Furthermore, the HSG regeneration mode includes: a former regenerative torque output control in which an engine RPM is converted by a controller 10 into regenerative torque output of the HSG 3 for about 1 second when an engine starts idling to charge a battery, and a latter regenerative torque output control in which the engine RPM is converted into the regenerative torque output of the HSG 3 after 1 second to about five seconds to continue to charge the battery, and an HSG driving mode.

Method for controlling hybrid starter and generator for improving fuel efficiency and eco-friendly vehicle

A method for controlling a motor based on a variable current controller gain may include a temperature function current applying mode in which when a torque command for the motor is detected by an inverter, 3-phase current to be applied to the motor is output to the motor in consideration of a motor temperature of the motor as a function.

Method for controlling motor based on variable current controller gain and eco vehicle thereof

An apparatus for controlling charge of a battery includes an auxiliary battery, a vehicle controller configured to determine a control mode of the auxiliary battery according to driving conditions of a vehicle, a DC converter configured to measure a state of the auxiliary battery and use the measured state of the battery to perform battery current control of the auxiliary battery according to the determined control mode, and a high voltage battery configured to supply power to the DC converter for charging or discharging the auxiliary battery.

Apparatus and method for controlling charge of battery

In order to diagnose a fail possibility and to compensate a charging state of a battery of an electric vehicle, by detecting an operating state of a battery while driving a vehicle that is equipped with a rechargeable battery, the present invention provides a method for controlling the charging state of a battery.
