Abstract

The present invention relates to a part time two-wheel / four-wheel drive conversion device and a method thereof, capable of reducing damage to a conversion tool which converts a drive mode or shocks by preventing the conversion of the drive mode if the drive mode is changed when an accelerator pedal is hit. The device comprises: a conversion mode detection unit to detect that the drive mode of a drive mode switch is converted; a pedal sensor to detect a stroke of the accelerator pedal; a control unit to generate a two-wheel conversion signal or a four-wheel conversion signal after comparing data detected in the pedal sensor with a threshold value; and a conversion operating unit which is operated by a conversion signal generated in the control unit and converts the drive mode from a two-wheel drive mode to a four-wheel drive mode or from the four-wheel drive mode to the two-wheel drive mode.

Description

technical field [0001] The present invention relates to a time-sharing two-wheel / four-wheel drive switching control device and method, and in more detail, relates to a time-sharing two-wheel / four-wheel drive that can use accelerator pedal information to prevent the interior of the transfer case from being damaged by the switching impact when switching drive modes A drive switching control device and method (part-time 2wd / 4wd conversion control device and method). Background technique [0002] Four-wheel drive vehicles have excellent stability and maneuverability on unpaved roads and on snowy or rainy roads by simultaneously driving the front and rear wheels of the vehicle. In consideration of economy, this four-wheel drive vehicle transmits the power to the front and rear wheels respectively after distributing the power to simultaneously drive the front and rear wheels as required during the process of only driving the front or rear wheels. [0003] The driving methods of t...
