Hyundai Ioniq: Hybrid Motor Control System / Description and operation
In a hybrid electric vehicle, HCU (an upper level controller), LDC (power converter), and inverter are integrated in the HPCU. HPCU is located on the left side of the engine compartment.
The inverter provides high-voltage AC current to the two motors (drive motor and HSG) and controls them optimally based on the driving conditions through communication with the HCU.
The inverter also changes the DC current from the high-voltage battery into 3-phase AC current that is required for the operation of the motor.
The inverter receives the torque commend from the HCU to control the motor. The motor acts as a generator during deceleration and braking and changes the 3-phase AC current into the DC current to charge the battery.
Inverter is also called a motor control unit (MCU) from the perspective of a controller.

The sensor may be limited when:
The pedestrian is not fully detected by the camera recognition system, for
example, if the pedestrian is leaning over or is not fully walking upright
The pedestrian is moving very quickly or appears abruptly in the camera
detection area
The pedestrian is wearing clothing that easily blends into the background,
making it difficult to be detected by the camera recognition system
It is difficult to detect and distinguish the pedestrian from other objects
in the surroundings, for example, when there is a group of pedestrians or a
large crowd
There is an item similar to a person’s body structure
The pedestrian is small
The pedestrian has impaired mobility
The sensor recognition is limited
The radar sensor or camera is blocked with a foreign object or debris
Inclement weather such as heavy rain or snow obscures the field of view
of the radar sensor or camera
The outside lighting is too bright (e...
