Method for processing of motor position data by a multi-core computer

A method for processing position data of an automotive vehicle motor, implemented by a multi-core electronic computer (1) comprising:

• at least one input, to receive a value of angular position of the crankshaft, from an angular position sensor of the crankshaft,
• a software module (10) for the production of data of angular position of the motor, adapted to generate a reference angular position (TDC0) on the basis of at least the information provided by said angular position sensor of the crankshaft, and
• at least one software module (20) for driving the motor as a function of the angular position data, able to receive from the software module (10) for data production the value of the reference angular position (TDC0),
• said method comprising:
• a step (100) of deactivation of each software module for driving the motor by the software module (10) for the production of data of angular position of the motor, followed:
• by a step (200) of activation of each software module for driving the motor by the software module (10) for the production of data of angular position of the motor,
• wherein the deactivation step (100) comprises:
• a step (110) of dispatching by the software module for the production of data of angular position of the motor, to each software module for driving the motor, of a deactivation command,
• followed by at least one step (120) of dispatching by the software module (10) for the production of data of angular position of the motor, to each software module (20) for driving the motor, of a request for confirmation that each software module (20) for driving the motor is deactivated, and
• the step (200) of reactivation of the software modules for driving the motor is implemented only when the deactivation of all the software modules (20) for driving the motor has been confirmed to the software module (10) for the production of data of angular position of the motor.
