A battery management device for preventing a battery from being damaged by a low voltage includes a storage configured to store a first protection voltage and a second protection voltage corresponding to a protection mode of the battery; a voltage detector configured to detect a voltage of the battery; a controller configured to confirm the detected voltage, to enter the protection mode when the detected voltage of the battery is the first protection voltage, to check a time point when the detected voltage of the battery is the second protection voltage, and to release the protection mode when a predetermined time elapses from the time point.

Battery management device, vehicle having the same, and method for controlling the vehicle

A transmission control method of a hybrid vehicle provided with a transmission having no reverse gear, may include performing a speed control of a motor with a target RPM corresponding to an existing gear step when a shift lever is switched from a drive D to a neutral N; and performing a backward travel with the existing gear step by engaging a gear of the existing gear step with a clutch and applying a reverse torque of the motor to the transmission when the shift lever is switched from the neutral N to a reverse R.

Hybrid vehicle and transmission control method thereof

An anti-jerk control system and method of an eco-friendly vehicle are provided to prevent a driver from sensing a difference in vehicle starting at an initial stage when the vehicle is parked on a downhill road. The anti-jerk control method uses a motor as a driving source and includes calculating an actual speed of the motor, calculating a model speed of the motor, and acquiring a gradient of a road, on which the vehicle is located, using a gradient detector. Additionally, the method includes determining a speed offset value that corresponds to the acquired gradient, compensating the model speed by the speed offset value, and calculating a motor vibration component using a difference between the compensated model speed and the actual speed of the motor. Then, anti-jerk compensation torque is calculated using the calculated motor vibration component.

Anti-jerk control system and method of eco-friendly vehicle

A circuit board () for a valve block () of a solenoid valve manifold is described. Each valve block () contains a valve which is actuated by either one single solenoid or by two solenoids. Both sides () of the circuit board () are provided with a circuit (). The first surface () of the circuit board () carries a single type valve circuit () for supplying one single solenoid with electrical energy. This first surface () can be mark e.g. with an 'S'. The second surface () of the circuit board () carries a double-type valve circuit () for supplying two solenoids with electrical power. This second surface () can be marked e.g. with a 'D'. The circuit board () is positioned in the respective valve block () with the first surface () or the second surface () facing upwards depending on whether a single- or a double-solenoid-valve is used in the respective valve block ().
