Abstract
A motor control apparatus for securing insulation performance includes: a temperature sensor detecting a temperature of a motor; an altitude detection means providing information on an altitude at which the motor is positioned; and a controller including a motor output map having a plurality of groups of map data in which motor output limit rates depending on temperatures of the motor are pre-stored for each preset altitude section, selecting one group of map data corresponding to the information on the altitude provided by the altitude detection means, and determining a motor output limit rate by applying the temperature detected by the temperature sensor to the selected group of map data.
Claims7
A motor control apparatus for securing insulation performance, the motor control apparatus comprising:
- a temperature sensor configured to detect a temperature of a motor;
- an altitude detection means configured to provide a current altitude of the motor at which the motor is positioned;
- and
- a controller including a motor output map having a plurality of groups of map data in which motor output limit rates depending on temperatures of the motor are pre-stored for each preset altitude section, the controller configured to:
- select one group of map data, among the plurality of groups of map data, based on the current altitude of the motor provided by the altitude detection means, and
- determine a motor output limit rate by applying the temperature detected by the temperature sensor to the selected group of map data,
- determine an output of the motor by applying the motor output limit rate determined based on the selected group of map data to a torque command or a current command of the motor determined by a driver of a vehicle including the motor, wherein the output of the motor is determined by decreasing the torque command or the current command of the motor according to the motor output limit rate.
A motor control method for controlling a motor, the motor control method comprising:
- receiving, by a controller, a current altitude of a motor from a navigator and a temperature of the motor from a temperature sensor;
- selecting, by the controller, a group of map data, among a plurality of groups of map data in which motor output limit rates depending on temperatures of the motor are pre-stored for each preset altitude section, by comparing the current altitude with a reference value;
- determining, by the controller, a motor output limit rate from the selected group of map data based on the temperature of the motor;
- determining, by the controller, an output of the motor by applying the motor output limit rate determined based on the selected group of map data to a torque command or a current command of the motor determined by a driver of a vehicle including the motor, wherein the output of the motor is determined by decreasing the torque command or the current command of the motor according to the motor output limit rate.
