Abstract: Provided is a method for filtering driving paths in order to stably track a path which is generated for various purposes, such as recognizing a lane and keeping or changing the lane, or avoiding an obstacle around a road. A driving path filtering system according to an embodiment of the present disclosure includes: a position recognition unit configured to recognize a position of a vehicle; a lane recognition unit configured to recognize a lane of a road; and a path generator configured to generate a path for the vehicle to travel on, based on a result of recognizing the position and a result of recognizing the lane, and to perform path noise filtering with respect to the generated path. Accordingly, a driving path can be stabilized by removing a path noise (error) by complementally filtering a lane recognition-based path generation method and a map-based path generation method according to a driving environment.

The high-speed switch switches a connection between the measurement target battery cell and the variable resistor. The measurement sensor detects a measurement voltage of the measurement target battery cell and a measurement current of the measurement target battery cell in an online state of the battery module. The controller derives an internal resistance of the measurement target battery cell through the measurement voltage and the measurement current.
