Unlike the warning system about the congress from the strip, which simply provide a visual or tactile warning, when the vehicle begins to shift from its strip, the system of retaining the strip uses brakes and / or torque attached to the steering column to help save the vehicle from leaving his lane. The retention of the lane first appeared on some car models in 2010. The force attached to the brakes or steering wheel is not strong enough to prevent the driver from creating a deliberate change in the strip. The system is designed to help the driver avoid unintentional deviation.
