Patent number: 9988040Abstract: A method prevents the stalling of the engine of a hybrid vehicle (1) equipped with an auxiliary motor (4) and wheels (R1 to R4), pistons (2a to 2d), tank (3), axle (5), drive shaft (6), gearbox (7), connections (8a, 8b), and computer (9). The method uses an estimate of the predicted instantaneous speed of the main engine (2) at its next top dead center, for the purpose of assisting the main engine in a stall situation, via the auxiliary motor which can supply sufficient power to it on a one-off basis to prevent it from stopping. The method defines two levels of instantaneous speed. If the predicted instantaneous speed is located in the intervention zone between the two levels, the auxiliary motor assists the rotation of the main engine to enable it to rotate in the same direction, without stalling.Type: GrantFiled: October 29, 2014Date of Patent: June 5, 2018Assignees: CONTINENTAL AUTOMOTIVE FRANCE, CONTINENTAL AUTOMOTIVE GMBHInventors: Damien Verdier, Benjamin Marconato, Jerome Lachaize

Publication number: 20180149543Abstract: A method according to the invention for checking the plausibility of the function of a pressure sensor in an injection system of an internal combustion engine includes acquiring a calibrated actuation profile, by which peak current values for opening at least one electrically actuatable injection valve are assigned to existing internal pressures. An existing internal pressure is measured in the form of an actual sensor pressure value by the pressure sensor. The method includes obtaining the electrical peak current value corresponding to the measured sensor pressure value from a calibrated actuation profile, such that the corresponding electrical peak current value acquired in this way is applied to the injection valve. Subsequently, an opening state of the injection valve is monitored in reaction to the applied electrical peak current value, and a functional state of the pressure sensor is assigned as a function of the opening state of the injection valve.Type: ApplicationFiled: January 30, 2018Publication date: May 31, 2018Applicant: CONTINENTAL AUTOMOTIVE GMBHInventors: Christoph Klesse, Tobias Ritsch, Claus Stephani, Thomas Uliana
