Assisting the driver with steering when making a lane change on an expressway
The Active Lane Change Assist is a function where the system assists the driver with steering operation when making a lane change. Without this function, the driver needs to operate the vehicle in three steps to make a lane change: 1) check traffic behind and beside the vehicle, 2) put on the turn signal, and 3) operate the steering. The Active Lane Change Assist reduced the driver burden while making a lane change.
How it works
For the Active Lane Change Assist to be activated, the system has to recognize that the vehicle is being driven on a regular lane of an expressway while having both Adaptive Cruise Control (ACC) and the Lane Keeping Assist System (LKAS) turned on. When the driver lightly pulls the turn signal lever a single tone is heard, indicating that the system has determined the driver requested a lane change based on the Active Lane Change Assist function and provides steering assist after checking the vehicle's surroundings.
How it helps
The driver Holds it until the single tone comes
on.
Using the camera and radars, the system checks the adjustment lanes for safety.
The system provides steering assist to make a
lane change.
When the driver requests a lane change by putting on the turn signal, the system uses the camera and radars to check the vehicle’s surroundings and determines whether a lane change can be made safely. If the system determines it is possible, it begins assisting the driver with steering operation. Once the lane change is completed, the Lane Keeping Assistance System (LKAS) gets re-activated, and the system assists the driver with steering to keep the vehicle near the middle of the lane.
On the other hand, if the system detects a vehicle approaching from behind at a higher speed and determines that it is not possible to make a lane change safely, it alerts the driver to the presence of the vehicle, abandons the lane change and keeps the vehicle in the current lane.
The system provides seamless steering assist for both lane keeping and lane change, which reduces the driver burden during a long drive and enables the driver to focus on safe driving.
Commitment of Honda
The steering assist provided by the system could lead to driver discomfort if the car is moving too slowly or too fast. Honda has tailored the system to make lane changes which feel natural and comfortable for the vehicle occupants.

The individual functions of the driver-assistive
system have limited capabilities (e.g. recognition capability and
control capability). Please do not overestimate the capabilities of
any function and drive safely while paying constant attention to the
vehicle’s surroundings.
A system may not work or perform adequately depending on road
conditions, weather conditions and vehicle conditions.
Depending on the model and timing of the market launch of the model, descriptions provided on this page and the actual functions available on customers’ vehicles may be different. For the functions available for each vehicle, please check the owners’ manual of the respective vehicle.
