Key Claims:

  • This is a system which checks the perimeter of the vehicle for any obstructions when you are changing lanes. Changing lanes is a constant source of danger when driving on the road, where drivers are taught to instinctively check their blind spot.

  • LCA works by utilising 2 radar sensors, these are constantly monitoring the environment around the vehicle. There are two stages to LCA:

    • If a vehicle is in the driver’s blind spot, there is usually an illuminated warning first on the wing mirror of the vehicle.

    • If this is ignored and the vehicle starts to change lane, the warning will give an audible alarm which alerts the driver.

    • In more premium vehicles, if this is then ignored again, the vehicle will automatically use the ESC to brake the wheels on one side of the vehicle to prevent it from changing lane.
