A ripple current sensing type motor controlling apparatus includes: an H bridge circuit switched depending on at least one control; a first resistor of which one end is connected to one end of the motor through the H bridge circuit and the other end is connected to a ground; a second resistor of which one end is connected to the other end of the motor through the H bridge circuit and the other end is connected to one end of the first resistor and is connected to one end of the motor through the H bridge circuit; and a controller calculating a RPM of the motor using a voltage across the first resistor in the case in which the driving power is applied to the motor and calculating the RPM of the motor using a voltage across the second resistor in the case in which the driving power is blocked.

Ripple current sensing type motor controlling apparatus and method thereof

Provided are an apparatus and method for controlling a ripple current sensing motor. An apparatus for controlling a ripple current sensing motor may include a first shunt resistor having one end connected to one end of a motor and the other end of the first shunt resistor connected to a ground, a second shunt resistor having one end connected to the other end of the motor and the other end of the second shunt resistor connected to the ground, a first amplifying circuit amplifying a first signal from one end of the motor, a second amplifying circuit amplifying a second signal from the other end of the motor, and a detector detecting a rotation amount and a rotation direction of the motor using a change in voltages of a first detection signal from the first amplifying circuit and a second detection signal from the second amplifying circuit.

Apparatus and method for controlling a ripple current sensing motor

The present disclosure provides a method and system for initializing a radio network for radio modules mounted in a vehicle, which can efficiently establish a radio network formed among the radio modules. In the method, radio modules and coordinators, transmit radio communication beacon frames. Each radio module searches for peripheral nodes by receiving radio communication beacon frames from peripheral nodes and generates a neighbor table with respect to the searched peripheral nodes. Each radio module selects a coordinator, using the neighbor table, and requests a connection to the selected coordinator. The connection request of each radio module with respect to the coordinator is then processed.

Method and system for initializing radio network for radio modules in vehicle

A system for providing parking information based on dual wireless communication including a vehicle terminal configured to connect to a server via a first wireless communication network when a parking information request is generated, and configured to connect to the server via a second wireless communication network if a connection via the first wireless communication network is failed, thereby receiving and displaying the parking information on a screen.

System for providing parking information based on dual wireless communication and method thereof

An electric vehicle is provided. A driver can remotely monitor battery charging associated operations and control a necessary function, thereby improving convenience of the driver of the electric vehicle.
