Active deceleration control of engine braking operation of a vehicle

An electronic control unit for controlling engine braking of a vehicle, the unit comprising:

• an electronic processor configured to:
• receive a deceleration request;
• determine a base engine braking level based on a vehicle speed and a vehicle gear;
• adjust the base engine braking level according to a brake pressure of the vehicle;
• 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.
