LANESENSE System: Description
The LaneSense system uses camera-based vision sensors to establish the vehicle's position on the road. Lane departure or drift is determined by a trajectory change and the absence of turn-signal activation. The Forward Facing Camera (FFC) module mounted near the rear view mirror identifies the lines on the road. The system then determines where the vehicle is placed between those lines and monitors the vehicle's movement down the road.
The system can be turned ON or OFF with a single hard button on the Integrated Center Stack (ICS). The LED on the button will inform the driver of the system status when the driver does not have the Driver Assist screen on the Instrument Panel Cluster (IPC).
If an unintentional lane drift with no turn signal occurs, the system will deliver visual and haptic warnings:
- If an unintentional lane drift (no turn signal applied) occurs, the IPC will display a yellow line as a visual warning to the driver.
- If the drift continues, a subtle introduction of torque feedback from the Electric Power Steering (EPS) system will occur serving as a haptic warning. However, intervention will not occur unless the driver's hands are on the steering wheel. The system will cancel if the driver's hands do not return to the wheel.
If an unintentional lane drift with no turn signal occurs, the system will deliver haptic and visual warnings:
- The visual warning will appear on the IPC as a flashing lane line corresponding to steering wheel torque.
- If the driver unintentionally drifts too far, the system provides a secondary visual National Highway Traffic and Safety Administration (NHTSA) compliant warning on the IPC.
