Intelligent Emergency Braking

Intelligent emergency braking reduces the impact velocity if the ASCM determines that a collision is unavoidable, even with driver intervention. It is not designed to prevent accidents from occurring. Typical activation of intelligent emergency braking is approximately 0.8 second before impact. During this 0.8 second period the speed of the sensing vehicle is reduced, thus reducing the impact energy.

If the ASCM determines a collision is unavoidable, it signals the ABS control module to apply emergency brake pressure to all of the brakes. On vehicles without active safety belts, emergency brake pressure is 50 bar (725 lbf/in² ) maximum. On vehicles with active safety belts, emergency brake pressure is 100 bar (1450 lbf/in² ) maximum.

When intelligent emergency braking is initiated the ASCM also signals the Restraints Control Module (RCM) to fire the front seatbelt retractors. For additional information, refer to:Safety Belt System Description And Operation

After the intelligent emergency braking function has activated, it is then disabled, as the vehicle is assumed to be damaged. After the vehicle has been repaired, the intelligent emergency braking function can be re-enabled using Jaguar approved diagnostic equipment.

The intelligent emergency braking function operates down to a vehicle speed of 10 km/h (6 mph), and will function even when forward alert and adaptive cruise control are switched off.

If the intelligent emergency braking feature is disabled for any reason, a related message is displayed in the message center.
