ESA at its core, helps a driver avoid a collision, before returning the vehicle to its path.
The key word here is ‘assist’. The safety system is only triggered when a human driver attempts to avoid an obstacle, and the pilot can override the system at any time.
What ESA does is help the driver put in the appropriate steering angle to avoid a crash, and then return to its lane. It does not steer for you.
But it’s already making its way into mainstream vehicles, including the Ford Edge, which will arrive in Australia with the Endura badge, will also feature the system.
Working alongside a full suite of safety systems, such as automatic emergency braking, ESA helps drivers avoid a collision, without taking full control of the vehicle.
Expect to see more cars proclaiming to have ESA as a feature in the near future.
