Systems and methods directed to active control of an engine braking operation. One aspect is directed to an engine braking control system for a vehicle. The system includes an electronic processor configured to receive a deceleration request, determine a base engine braking level based on a vehicle speed and a vehicle gear, and adjust the base engine braking level according to a brake pressure of the vehicle. The electronic processor is further configured to generate, based on the adjusted base engine braking level and the deceleration request, a target deceleration profile, determine, based on the target deceleration profile, an engine torque demand, and control an engine braking operation of the vehicle by adjusting a torque of an engine of the vehicle according to the engine torque demand, wherein the engine torque demand is updated during the engine braking operation.
