ISG), and wheels.

The hybrid vehicle includes a hybrid control unit (HCU) for controlling the overall operation of the hybrid vehicle, an engine control unit (ECU) for controlling the operation of the engine, a motor controller (motor) a control unit (MCU), a transmission control unit (TCU) for controlling the operation of the transmission, and a battery control unit (BCU) for controlling and managing the high voltage battery.

The engine controller may be referred to as an engine management system (EMS). The battery controller may be referred to as a battery management system (BMS). The starter generator may be referred to as a hybrid starter & generator (HSG).

The hybrid vehicle may engage or disengage the engine clutch according to acceleration / deceleration will, vehicle speed, state of charge of the battery, or the like depending on the operation of the driver's accelerator pedal and brake pedal, mode); An HEV mode (hybrid electric vehicle mode) in which the rotational force of the engine is used as the main power and the rotational force of the motor is used as the auxiliary power; A regenerative braking mode for recovering braking and inertia energy during braking or inertia of the vehicle through power generation of the motor and charging the high voltage battery; And the like.

When the hybrid vehicle is switched from the EV mode to the HEV mode, the engine clutch is engaged after the engine speed and the motor speed are synchronized, so that the torque fluctuation is not generated during the power transmission process between the engine and the motor, .

In this way, the hybrid vehicle utilizes both the mechanical energy of the engine and the electric energy of the high-voltage battery, utilizes the optimal operating range of the engine and the motor, and recovers energy from the motor during braking.

Accordingly, an energy monitoring device for energy management of such a hybrid vehicle is required, and it has a shape and size similar to those of a general car navigation device.

Navigation is largely classified into a stationary type and a flush type, and a stationary type is installed on the upper side of a dashboard of a vehicle or attached to a front glass of a vehicle, and the flush type is installed integrally with a center fascia of a vehicle Most cases.

The stationary type occupies a certain space at the upper part of the dashboard, which may interfere with the securing of the front view. Especially, in the case of the glass absorption type, the mounting surface often drops depending on the temperature or the use condition. On the other hand, in the case of the buried type, there is a disadvantage that it is not easy to repair or replace even if self-defective occurs.
