Electronically Controlled Deceleration (Ecd)

Electronically Controlled Deceleration (ECD)
ECD responds to the requests of the ACC (Active Cruise Control) signals.
DSC executes braking retardation when deceleration is requested by ACC.
This is performed by way of an automatic brake intervention at the four disc brakes, dependent on the vehicle speed, the distance and the speed of the vehicle travailing in front, with max. 3 m/s2 deceleration.
On downhill gradients at a preselected driving speed, ECD maintains the driving speed continuously at the preset value by way of automatic brake intervention.
The new brake pressure sensors can guarantee more uniform braking at the front and rear axles. This allows longer activation without compromising on comfort or overheating of the brakes on one axle.
In the case of automatic braking, the brake lights are activated in line with legal requirements.
Only from a deceleration > 1 m/s2 will a brake light activation be performed by the light module (LM). This prevents the brake lights from coming on frequently and for brief periods.
