Method for managing a starting phase of a hybrid vehicle
A method is proposed for synchronizing a combustion engine in a hybrid vehicle provided with an electric motor, comprising the following steps: applying an initial rotation speed setpoint value to the electric motor (typically 2,500 revolutions per minute), then synchronizing the combustion engine on the basis of the rotation signals from the camshaft and the crankshaft. In the event of a camshaft signal failure, an initial combustion engine position assumption is selected from among a plurality of possible assumptions, and injection tests are performed by adjusting the rotation speed setpoints. Once the idle speed setpoint has been reached, the rotation speed setpoint value of the electric motor is reduced to a new value (typically 2,000 revolutions per minute). If the assumption is confirmed, the speed setpoint process is stopped; if not, another assumption is tested until confirmation occurs.

The invention relates to a method for determining the angular position of an unevenly toothed camshaft target. A sensor generates a signal upon each passage of the teeth, creating significant edges. A computing unit processes this signal in order to determine the time intervals between these edges, as well as to store theoretical ratios, tolerance intervals, and confidence intervals. Suspicion meters are associated with each edge. By computing real ratios based on the measured intervals, the unit discriminates the candidate edges: the edges that do not correspond to the tolerances are removed, those corresponding to the confidence intervals reset the suspicion meter, and those outside the confidence intervals increase the suspicion meter until they are removed. The steps are repeated until a single candidate edge is identified. The angular position of the target is then determined based on this single edge.

Method for starting an internal combustion engine comprising a camshaft associated with an electric variable valve timing device
A method for starting an internal combustion engine including a camshaft provided with an electric continuous variable valve timing device. The method includes: (a) applying a maximum voltage to the electric actuator, then (b1) initiating a timer Ts during which a maximum voltage continues to be applied to said actuator and, in parallel, (b2) starting a synchronization of the combustion engine, then (c) if the timer expires before the end of the synchronization of the combustion engine, incrementing the value of the failure counter and reiterating (a) to (c) if the value of the failure counter is less than a predetermined number Nmax, otherwise, stopping the application of a voltage to the actuator, the combustion engine being synchronized.

A control method for managing an upshift in a gearbox, the shift being intended to transition from a starting gear to a target gear, without declutching, the gearbox comprising a selection shaft movable between a first position corresponding to the starting gear and a second position corresponding to the target gear, an angular position sensor providing a voltage value corresponding to a current angular position of the selection shaft, the method comprising:
iteratively acquiring the voltage value corresponding to the angular position of the selection shaft;
when the current voltage value (61) becomes greater than a first predetermined threshold (VS1), then triggering a reduction in the engine torque;
when the current voltage value increases and becomes greater than a second predetermined threshold (VS2), then cancelling the reduction in engine torque.
