Definitions

• the invention relates to a temporary method for the temporary lifting of organic protections for a motor vehicle and the corresponding motor vehicle.
• the invention finds a particularly advantageous application with vehicles with a heat engine and / or one or more electric motors, a manual or automated gearbox, and possibly high battery type electrical systems. and / or low voltage, alternators, electric converters, whose performance is limited by organic protections.
• organic protections called indifferently in the following document organic limitations are provided to limit the performance of the various organs of the vehicle in order to preserve and increase their service life. These organic protections may for example consist of a limitation of the maximum operating torque of the engine or electric traction machines for a hybrid vehicle.
• the invention aims to remedy this drawback by proposing a method for lifting organic protections of a motor vehicle characterized in that it comprises the step of temporarily lifting at least one organic protection of the vehicle following a request. performance of the driver in the case where a life situation requiring such an organic protection lift has previously been detected from information from at least one driver assistance system.
• the invention thus optimizes the lifts of organic protection by restricting them to specific life situations requiring the availability of maximum performance of the vehicle.
• the vehicle components which are less often stressed at critical operating points, are better protected; while the maximum performance of the vehicle remains available longer in the life of the vehicle.
• the invention allows to control the performance of organs throughout the life of the vehicle, it is possible to optimize the size, weight, and characteristics to effectively meet the constraints of very stringent emission and consumption limits imposed on car manufacturers.
• the organic protection or lifted depends on the detected life situation.
• an organic protection lift duration and / or a number of kilometers traveled with an organic protection lift is specific to each organic protection.
• the method includes the step of imposing a calibratable delay, said confirmation delay, starting from a request for performance of the driver's share in which the performance request must be maintained by the driver to authorize an effective lifting of the organic protection (s).
• the information for detecting life situations allowing lifting of the organic protections are derived from an ACC type radar and / or a control camera.
• the ACC type radar provides at least one of the following information: a speed of a vehicle followed, a distance with the vehicle followed, a period separating the vehicle from the vehicle followed.
• the control camera makes it possible to detect an overtaking of a vehicle and is able to read traffic signs to deduce a corresponding life situation among in particular a motorway entry, a lane end overtaking, a steep road, a passage to a congestion charge.
• the method comprises the step of raising at least one organic limitation from the following organic limitations: a thermal limitation, a torque limitation of a vehicle engine, a pressure limitation on a rail injection, a torque limitation on a belt of an alternator, a static and dynamic limitation of a gearbox, a performance limitation of electrical systems, such as an electric machine and / or a battery.
• the invention also relates to a motor vehicle provided with an onboard computer having a software instruction storage memory for implementing the method according to the invention.
• FIG. 1 shows a functional representation of the optimization system of organic protection lifts according to the invention
• FIG. 2 is a table indicating the throttling lifts per organ as a function of the critical life situations detected;
• Figure 3 shows a diagram of the main steps of the method of removing organic protections according to the invention.
• Figure 1 shows the various modules of a system 1 for optimizing the lifting of organic protections of a motor vehicle according to the detected life situations requiring provision of the maximum performance of the vehicle.
• the system 1 comprises an onboard computer 2 in relation on the one hand with two driving assistance systems consisting in the occurrence of an ACC 3 type radar (for "Adaptive Cruise Control"). and a control camera 5, and on the other hand with a man-machine interface 8 capable of translating requests from the driver into information that can be processed by the on-board computer 2.
• ACC 3 type radar for "Adaptive Cruise Control”
• the on-board computer 2 includes a supervisor 21 for driving assistance information and requests from the driver and a module 22 for coordinating the lifting of the organic protections, in particular for a motor 10, an injection rail 1 1, a gearbox 12, an alternator 13, one or more electric machines 14 in the case of a hybrid vehicle and batteries 15.
• the functionalities of the Supervisor 21 and coordination module 22 are implemented in a memory of the edge computer 2 by software instructions.
• a first step 101 the supervisor 1 receives information 11 from the driving assistance systems 3, 5 to detect different life situations, called critical, requiring lifting of organic protections of the vehicle.
• the radar ACC 3 provides the information relating to a vehicle speed followed, a distance with the vehicle followed, as well as the time separating the two vehicles.
• the control camera 5 makes it possible to detect in particular a situation of overtaking of a vehicle and to read traffic signs to deduce a corresponding life situation such as a motorway entry, an end of overtaking lane, a steep road, or a passage to a congestion charge.
• the supervisor 21 receives, in a step 102, a performance request 12 from the driver resulting for example in a high torque demand via a support of the accelerator pedal beyond a certain threshold expressed as percentage of support of the accelerator pedal.
• the supervisor 21 then coordinates the various information 11 with the performance request 12 from the driver to allow or not the lifting of the organic protections of the vehicle according to the detected life situation.
• the supervisor 21 imposes a calibrated delay, said confirmation delay Te, starting from the detection of the performance request from the driver in which the performance request must be maintained by the driver during a step 103 to allow effective lifting of organic limitations.
• the confirmation delay Te is also useful for confirming any significant torque request, regardless of the life situation, if the driver depresses the accelerator pedal until the hard point is exceeded. Indeed, a brief support of the accelerator pedal beyond the hard point may reflect a simple need for output regulator mode or speed limiter requiring no lifting limitation. To allow the lifting of the organic protections, it will be necessary to confirm the torque request by keeping it in the confirmation period Te. In the case where the high torque demand falls back within the confirmation period Te, the lifting of the organic protections will not be performed by the on-board controller 2.
• the confirmation delay Te is of the order of 2s. If necessary, the duration of the delay Te may depend on the critical life situation detected. Alternatively, the confirmation delay Te may in certain cases be zero, in other words, calibrated at 0s, so that the lifting of the organic protections can be carried out as soon as a demand for performance is detected by the driver without waiting for a confirmation of this application.
• the supervisor 21 transmits in a step 104 information 13 describing the critical life situation to the coordination module 22, which for each of these situations, determines the organs 10-15 whose protections must be lifted.
• the supervisor 21 transmits information 14 of the set organic limitation issue corresponding to the organs 10-15.
• the thermal limitations, the torque limitations of the engine 10, the pressure limitations on the injection rail 1 1, the static and dynamic limitations of the the gearbox 12, the limitations of the electrical systems 14, 15 as well as the torque limitations on the accessory facade, in other words all the possible organic limitations, are removed.
• the limitation lifts are independent of one another and depend on the life situation detected by the supervisor 21.
• a counter C1, C2 respectively spent time and / or kilometers traveled in unrestricted rolling is specific to each organic protection.
• the lifting of the limitations will be more or less severe depending on the rolling threshold beyond limitation of each member, which allows to distribute the availability of performance over the life of the vehicle.
• the driver's performance request may be made via an interface other than the accelerator pedal, such as a button dedicated to the driver.
• implementation of the functionality may be physical or tactile in which case it may appear on the central digital console of the vehicle.
• the list of organic limitations presented may be supplemented by other limitations adapted to each critical life situation detected.
• the vehicle is equipped with a single driver assistance system (the radar ACC 3 or the control camera 5) or other type of driver assistance sensors.
