A Maneuver-based Lane Change Assistance System

Lane change is a very demanding maneuver. Therefore, a maneuver-based lane change assistance system has been developed which, by means of a single-task-combining assistance concept, supports the driver from the driver's first lane change intention through the final movement of the vehicle from the initial to the target lane, without automatization of the vehicle guidance. The maneuver recommendation covers lane change timing, lane change direction as well as the required acceleration or deceleration. The system architecture with its modules to estimate the maneuver recommendation is described as well as the HMI which presents the information to the driver on a display and by an additional steering-wheel torque. A core assistance module geared to the driver's needs and the detection of driver's intention based on motivators, inhibitors and indicators is explained in detail.
