Abstract: Provided is a tagless mobile ticket service method, which enables a user possessing a wireless terminal, in which a payment application capable of paving bills is installed, to pay for usage fees without being tagged at a ticket gate machine, The tagless mobile ticket service method includes: a user entry detecting step in which a ticket gate machine senses that a user possessing a user terminal accesses a ticket gate; a user information processing step in which bill payment information is acquired from the user terminal; a validity confirmation step in which the validity of the bill payment information is determined; and a user fee processing step in which a door is opened and a bill is paid using the bill payment information, if it is determined that the bill payment information is valid.

Abstract: A cooling system for a bus may include a heat dissipating plate mounted on a roof panel of a top of a bus and cooling heated fluid with wind, and an actuator connected to an air tank, selectively actuating the heat dissipating plate and adjusting an inclination angle between the heat dissipating plate and the roof panel.

Abstract: An electrohydraulic power steering system includes a sensor for detecting steering information, a motor pump unit generating a hydraulic pressure for assisting steering power depending on a driver's steering wheel operation, and a hydraulic cylinder driven with the hydraulic pressure supplied from the motor pump unit to assist the steering power. A control method of the electrohydraulic power steering system includes acquiring steering angle information depending on the driver's steering operation and information on a steering torque applied through a steering wheel at the time of operating the steering wheel; determining a target steering torque depending on the acquired steering angle; and variably controlling a motor rotational speed of the motor pump unit so that the steering torque acquired through the sensor satisfies the target steering torque.

Abstract: A steering apparatus for a HEV which assists in providing power steering regardless whether an engine is being operated, and a method of controlling the same. More specifically, one or more detectors detect a vehicle speed, a steering angle, and an engine RPM, and a pump is controlled according to the engine RPM based upon signals received from the one or more detectors. Additionally, an electric motor unit (EMU) mounted to a steering column unit separately from the power steering pump, provides power assisting in steering the vehicle. Also a hybrid control unit (HCU) receives a signal from one or more of the detectors to control a power steering pump and an electric motor unit as required.
