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.

Abstract: A method for controlling a power steering system utilizes a vehicle having a motor, a controller coupled to the motor, and a steering assembly. The method includes detecting a steering rate using the controller. A base level steering damping is computed using the steering rate. At least one approximate vehicle acceleration is determined. A steering torque of the steering assembly is sensed through a torque sensor configured to sense the steering torque of the steering assembly. Moreover, a user torque is determined using the torque sensor. A damping boost is computed using the user torque and the at least one approximate vehicle acceleration. A final steering damping gain is determined using the base level steering damping and the damping boost. The final steering damping gain is applied to the steering assembly to minimize unwanted feedback to the steering assembly.

Abstract: Disclosed is a method for the diagnosis of a digital valve in a fuel injection system. In the diagnosis, a diagnosis current is applied to the digital valve with an intensity and for a hold time that are predetermined by experiment on digital valves identified as being fault-free, this intensity and this time being recognized as being sufficient for an inflection on a curve of the closing current to be detected in the hold time. Measurements are taken at more than 3 kHz of the diagnosis current added to the induced current in the hold time. When an inflection on the current curve is detected in this hold time, it is concluded that the valve is working correctly. When no inflection on the curve is detected in this hold time, it is concluded that the valve is faulty.

An instant at which the pump piston passes through top dead center is estimated as a function of an instant at which the position of start-of-opening of the digital valve appears.
