Emergency Brake Assist

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

Emergency Brake Assist (EBA) helps the driver in emergency braking situations by automatically increasing the applied braking effort.

There are 2 situations when the Anti-lock Brake System (ABS) control module will invoke EBA:

When the brake pedal is pressed rapidly.
When the brake pedal is pressed hard enough to bring the front brakes into ABS operation.

When EBA is active, the ABS control module increases the hydraulic pressure to all of the brakes until the threshold for ABS operation is reached. This action applies the maximum braking effort for the available traction. The ABS control module monitors the brake pedal switch and the pressure sensor within the Hydraulic Control Unit (HCU). It is needed for a sudden application of the brakes. With the brake pedal pressed, if the rate of increase of hydraulic pressure exceeds the predetermined limit, the ABS control module invokes emergency braking.

The brake pedal can be pressed hard enough to bring the front brakes into ABS operation. In this case the ABS control module increases the hydraulic pressure to the rear brakes up to the ABS threshold.

EBA operation continues until the driver releases the brake pedal sufficiently. Then the hydraulic pressure drops in the HCU below a threshold value stored in the ABS control module.

During an emergency braking situation the ABS control module activates the warning indicators. For additional information, Refer to: EXTERIOR LIGHTING
