Range Rover 2017 Lane Keep Assist (LKA): Why It Might Not Be Worth the Hype

Lane Keep Assist (LKA) in the 2017 Range Rover has garnered attention, but it’s important to understand its functionality and limitations. The system tends to “ping pong” the vehicle between lane markings, which is similar to basic Lane Departure Warning (LDW) systems. This is not comparable to Lane Centering Assist (LCA), a more sophisticated feature that actively keeps the vehicle centered in the lane, which is not offered by Jaguar Land Rover (JLR) in this model year, and typically found in brands like Kia and Hyundai.

For those considering retrofitting LKA to older Range Rover models, it’s crucial to note the technical challenges. While vehicles equipped with self-parking features already possess some necessary hardware, the 2017+ Range Rovers operate on a FLEXRAY network, unlike the 2014-16 models which utilize CANBUS. This network difference creates a significant communication barrier, making a straightforward retrofit difficult. Furthermore, current diagnostic tools lack complete support for Configuration Control Files (CCF) in 2017+ models due to this network change, although this is an area under development.

While technically feasible, retrofitting LKA would require considerable effort for a feature that offers limited real-world benefit due to its basic functionality. Therefore, focusing on other enhancements might be a more practical approach.

In contrast to the complexities of LKA retrofit, features like street sign recognition are simpler to enable, often requiring just a CCF update if the necessary camera hardware behind the rearview mirror is already present.
