Lateral Support (LDW / LKA / LCA)
TRW's lateral support systems include Lane Departure Warning (LDW), Lane Keeping Assist (LKA) and Lane Centering Assist (LCA). These technologies use a forward-facing video camera mounted behind the rearview mirror to detect lane markings alongside many types of roadways.
Lane Departure Warning
LDW is comparable to a virtual road rumble. Drivers who unintentionally cross a road lane mark-ing or the edge of the road receive a visual, audible or haptic warning helping to remind them to correct the situation. Haptic feedback options include a vibrating steering wheel.
Lane Keeping Assist
LKA takes information from a video sensor and integrates it with TRW's electric steering (EPS) system, providing a counter-steering torque to help guide the driver back to the center of the lane. The limited corrective steering torque alerts drivers to adjust the vehicle trajectory. Hands-off detection helps to avoid misuse of the system.
Lane Centering Assist
LCA gently applies a torque to the steering system in order to support the driver in keeping the vehicle in the center of the lane. The induced torque is generated by the Electrically Powered Steering system. Hands-off detection helps to avoid misuse of system for autonomous driving.
For safety reasons, LKA and LCA can be easily overruled by the driver at any time.
