Definitions
- the present invention relates to a method for controlling the operation of a power unit of a motor vehicle equipped with a computer.
- An object of the invention is to overcome the previous problems, and to provide a method of controlling the operation of a powertrain of a motor vehicle with a calculator, imperceptible to the driver.
- the step of determining a need for automatic reactivation of said powertrain comprises a sub-step of activating / deactivating a fault level outputting information comprising: • information representative of an ongoing analysis of the powertrain context;
- the step of determining a need for automatic reactivation of said powertrain comprises a substep of inhibition or interruption of automatic reactivation of said powertrain, outputting, to said sub step of activating / deactivating a fault level, information comprising:
- Information representative of an interruption of automatic reactivation of said powertrain based on information comprising: information representative of a state of the powertrain; information representative of an external prohibition of automatic reactivation of said powertrain; information representative of an external detection of the presence of the driver; an information representative of the position of the accelerator pedal; information representative of a contact on a primary brake contactor; ⁇ Information representative of a contact on a secondary brake contactor; and
- the step of determining a need for automatic reactivation of said powertrain comprises a substep of untimely reset confirmation of the computer, outputting, to said sub-step of activation / deactivation of a fault level, information comprising information representative of a confirmation of untimely reinitialization of the computer, based on information comprising:
- the step of determining a need for automatic reactivation of said powertrain comprises a sub-step of rehabilitation of the fault levels, outputting, to said activation substep / deactivation of a fault level, information comprising information representative of a restoration of the defect levels in the absence state, based on information comprising information representative of a state of the powertrain.
- said substep of activation / deactivation of a fault level receives, as input, information representative of the speed of the vehicle, and in the case of the presence of an internal combustion engine, a information representative of a state of the internal combustion engine.
- a motor vehicle comprising a computer and a powertrain, said computer being adapted to implement a method as described above.
- FIG. 1 illustrates the environment of the method according to one aspect of the invention.
- FIG. 2 illustrates the method according to one aspect of the invention.
- the elements having the same references are similar.
- Figure 1 is illustrated the method of the invention in its environment.
- Safety and regulatory information means external data or internal control of the vehicle to: ⁇ confirm the inadvertent nature of the software reset to estimate or limit the duration of the software reset to calculate the time elapsed since the software reset, securely detect the presence of the driver
- the result of the processing of the information carried out by the determination V is transmitted in the form of fault levels to the functions IV of fault management and reconfiguration (classic in a control automobile control).
- the automatic reactivation of the GMP is a success: the driver continues to use his vehicle despite the history of unintentional reinitialization of the computer ( with a high probability that the driver did not feel the anomaly).
- the determination V then informs the IV functions that the automatic reactivation of the GMP is a success: the level of default initially transmitted to the present state causing the automatic reactivation is transmitted in the absent state;
- the determination V again informs the functions IV which then interrupt the reactivation automatic GMP by informing the supervision III, and if the interruption does not originate a driver action, the IV functions also inform the driver II for example by a human-machine interface or HMI, such as a STOP light.
- HMI human-machine interface
- the IV functions inform the driver II by an HMI such as a STOP LED.
- driver information II by HMI is transmitted in the absent state.
- FIG. 2 illustrates in more detail the various sub-steps or sub-functions of the method according to one aspect of the invention, and particularly of the step of determining a need for automatic reactivation of said powertrain, following an untimely step of resetting said computer having deactivated said powertrain, according to information E1, E2, E3, E4, E5, E6, E7, E8, E9, E10 of the context in which the vehicle is located.
- a sub-step V_04 for activating / deactivating a fault level outputs information comprising:
- An information E6 representative of a contact on a secondary brake contactor and • E7 information representative of the speed of the vehicle.
- the automatic activation of the GMP is inhibited (can not begin) as soon as one of the following conditions is satisfied: ⁇ the driver is not considered as present (Condition 1);
- the driver can be considered as present (Condition 1) via several criteria:
- the primary contactor means the main sensor and sufficient (except in case of failure) to reflect the brake pedal support and by secondary contactor the sensor used in redundancy of the primary contactor which makes it possible to reflect (except in case of failure on this second sensor) the support on the brake pedal.
- Each criterion is considered only for a state of the GMP at rest or inactive, when the information used is valid. If a criterion is verified then we add an increment that can be calibrated to a sum representative of the presence of the driver inside the vehicle.
- timings delay_a and timeout_b as well as the speed of movement of the vehicle and the presence of the driver allow to adjust to regulatory and / or safety requirements if necessary (eg maximum time allowed rehabilitation, rehabilitation allowed at no speed). null only ).
- a sub-step V_02 for confirmation of untimely reinitialization of the computer outputs, to the substep V_04 of activation / deactivation of a fault level, information comprising a representative information E'3 a confirmation of untimely reinitialization of the computer, based on information comprising:
- An external detection criterion E8 (for example derived from the history of each reset of the computer);
- This criterion is an indicator of the duration of the soft software reset (if this reset exceeds a certain time, the close intelligence of the discontactors will open them for security)
- Each criterion is considered only for a state of the GMP at rest or inactive, when the information used is valid. If a criterion is verified then we add an increment that can be calibrated to a sum representative of the presence of the driver inside the vehicle. When this sum is greater than or equal to a minimum threshold that can be calibrated, it is considered that there is indeed a computer reset inadvertent.
- a sub-step V_03 for the recovery of the fault levels outputs, to the substep V_04 of activation / deactivation of a fault level, information comprising a representative information E'4 of a rehabilitation of the defect levels in the absence state, based on information comprising information (E1) representative of a state of the powertrain.
- Inactive GMP defects following an unexpected reinitialization of the computer forced to absent according to several criteria depending on the state of the GMP.
- the state of the GMP is maintenance after deactivation of the GMP is that the user cut his vehicle by using the ignition key before or during the automatic reactivation of the GMP.
- the sub-step V_04 for activating / deactivating a fault level also receives, at the input, an information item E7 representative of the speed of the vehicle, and in the case of the presence of an internal combustion engine, an information E10 representative of a state of the internal combustion engine.
- the absent or present state of the fault levels following an unwanted computer reset is transmitted to the IV functions when one of the following three conditions is verified:
- the choice of the level of fault returned to the present state depends on the speed of the vehicle, the state of the engine and the authorization of action automatic.
- the present invention avoids a possible panic driver, due to a deceleration and lack of response of the vehicle if a reset of the computer occurs during running and under certain conditions by automatically rehabilitating the GMP.
- the invention makes it possible to avoid certain dangerous situations due to the possible deceleration during a reinitialization of the computer and / or to avoid complaints from customers.
