METHOD FOR OPTIMISING THE TIME GRADIENT OF THE PRESSURE INCREASE IN AN INJECTION SYSTEM OF A HYBRID MOTOR VEHICLE

Disclosed is a method for optimizing the time gradient of the pressure increase in a fuel injection system of a hybrid motor vehicle. The method determines and uses the engine torque generated by the electric machine of the vehicle to reduce the engine torque generated by the internal combustion engine of the vehicle and allow the high-pressure pump of the internal combustion engine to generate, if applicable, a higher value of the time gradient of the pressure increase in the common supply chamber of its injection system.
