Brake assist is a driver-assist safety feature that intervenes to help a car stop faster during emergency braking.

The system detects when a driver engages the car’s brake so hard without an appropriate braking response. So, it releases extra braking force to shorten the braking distance, thereby averting unexpected crashes.

Is Brake Assist The Same As ABS?

Brake assist is not the same as ABS (Anti-lock Braking System). However, they synergize to deliver optimum braking performance. The brake assist feature helps to deliver extra force to the brake pedal to enable it to press down to engage the brake in a case of emergency.

Conversely, the anti-lock braking system (ABS) helps to maintain traction on your car’s tires while slowing down to a halt. This enables the driver to have good control over the steering wheel.

The ABS typically prevents your car’s wheels from experiencing a sudden lock up while you carefully steer to find safety. So, while their operations are closely related, brake assist and anti-lock braking system features are two separate functions that jointly offer a safe driving experience.
