Honda HR-V: Lane Departure Warning System Description - Overview
The lane departure warning system determines if the vehicle is unintentionally leaving the lane in which it is travelling. By identifying the lane markings in reference to the vehicle position, the system issues an audible warning and visual warning in the multi-information display when vehicle lane departure occurs.

Operation
- To control the lane departure warning system, the multi purpose camera unit receives information from the integrated camera, VSA modulator-control unit and the PCM, and sends commands to the gauge control module and multi-information display to issue warnings to the driver.
- The multi purpose camera unit looks at signals from the gauge control module and VSA modulator-control unit to determine if the driver is actively controlling the vehicle or not. Use of the turn signals and brakes indicate the driver is controlling the vehicle, and no warnings would be issued.

- Metallic projections on the road
- Metallic manhole and drain covers

- Low-speed, heavy traffic (such as in a traffic jam)
- Being cut-off by a slower vehicle
- Approaching a vehicle stopped at an angle
