Abstract:
PURPOSE: The current driving power state used for the vehicles drive can be recognized visually easily to operator, the various information be distinguished in advance to the fixed color, and the information can be easily transferred to operator. CONSTITUTION: A drive power display system for hybrid electric vehicle comprises a vehicle controller, a display controller, and a display unit. The vehicle controller transmits a message the driving power rate of the engine and motor, and the status information of the engine and motor. Based on the driving power rate, which the display controller is received from the vehicle controller the motor and the status information of the engine, the control signal for indicating the information is outputted. In the display unit, drive is controlled with the control signal outputted from the display controller. The driving power rate of the engine and motor, and the status information of the engine and motor are indicated. The display unit comprises a bar(14) and a delimiter(15). The bar shows the full power, and in the delimiter is the bar, the driving power rate of the motor and driving power rate of the engine are compartmentalized.

PURPOSE: A starting control method of a hybrid vehicle is provided to start an engine by combining an engine crank pulley and an ISG and operating the ISG. CONSTITUTION: An air-conditioner switch is turned on. It is determined that an engine is turned on or off when the air-conditioner is turned on. It is determined that an engine-ON signal is demanded when the vehicle is driving as an electric mode in the turn off state of the engine. A compressor of the air-conditioner is turned off when the engine-ON signal is demanded. The engine crank pulley is combined with ISG(Idle Stop and Go) and the ISG is driven and the engine is started.
Abstract:
PURPOSE: An electromotive water pump control system for hybrid vehicles is provided to improve the fuel efficiency because the electromotive water pump operates by considering the indoor heating of the vehicle and cooling of an engine. CONSTITUTION: An electromotive water pump control system for a hybrid vehicle comprises an ECU(Engine control unit) (11), a FATC(Full Automatic Temperature Controler) (12) and a HCU(Hybrid Control Unit)(13). The ECU calculates the operating RPM(Revolution Per Minute) of a water pump and power for cooling the engine and indoor heating of the vehicle. The HCU operates the electromotive water pump with a maximum value of the operating power of the water pump from the ECU and a full automatic temperature controller for the indoor heating of the vehicle and cooling the engine.
