Definitions

  • TITLE RESTART CONTROL DEVICE FOR A COMBUSTION ENGINE OF A HYBRID VEHICLE
  • the invention relates to hybrid vehicles which comprise a thermal engine and a non-thermal driving machine respectively consuming fuel and energy (or power) stored in at least one energy storage means to provide torque , together or separately, for at least one train.
  • the invention relates both to electrical energy storage means and to hydraulic or pneumatic energy storage means. Furthermore, the invention concerns both the case in which the thermal engine and the non-thermal driving machine provide two torques for the same train and the case in which the thermal engine and the non-thermal driving machine provide two torques respectively for two trains.
  • Some hybrid vehicles have an automatic function known as “crawling” (or “crawling”), allowing them to continue to move smoothly at low speed (typically from 0 to 12 km/h on the flat or on a slope) thanks to the supply of a variable torque as soon as the speed of the vehicle changes below a threshold and the driver does not act on the pedal accelerator.
  • This mode of travel or driving, referred to as “crawling mode” throughout the text of this document, allows the driver to maneuver his vehicle more easily by only needing to control the steering wheel and temporarily operate the pedal. of brake.
  • Patent document WO-A1-201938492 discloses a control device anticipating the start of the thermal engine so as to ensure the creeping mode when, for example, the non-thermal driving machine is unable to ensuring the creeping mode on its own according to the state of the energy storage means. [006] Unfortunately, this control device presupposes that, in creeping mode with only the non-thermal driving machine generating propulsion, the maximum power that the non-thermal driving machine can deliver, independently of the state of the energy storage, is sufficient in all cases of life of the vehicle in creeping mode.
  • hybrid vehicles which include a low-capacity non-thermal driving machine, the power or torque of which may be insufficient in particular life situations of the vehicle in creeping mode, for example when the vehicle is heavily loaded and /or on a slope, and causing the vehicle to roll back while the combustion engine is restarted.
  • the object of the invention is to remedy this lack by proposing a control device suitable for hybrid vehicles which include a low-capacity non-thermal driving machine without there being any possibility of these vehicles rolling back.
  • the subject of the invention is a control device for a vehicle, this vehicle comprising:
  • a brake control device coupled to a braking circuit of the vehicle
  • this control device comprising means for control triggering the restart of the combustion engine, when:
  • the vehicle is traveling at a speed lower than a first threshold speed
  • the vehicle is rolling with a negative acceleration lower than a threshold acceleration
  • the brake control device is not actuated by the driver.
  • this control device advantageously makes it possible to restart the heat engine before the vehicle exhibits a reversing speed or a reversing displacement, even though this vehicle is in conditions increasing the probability of occurrence of a reversal .
  • this control device will prevent the appearance of a recoil even for a light hybrid vehicle, that is to say having the low-capacity non-thermal driving machine. It is then no longer useful to have a high capacity non-thermal driving machine.
  • this control device comprising means for controlling the vehicle in a creeping mode, characterized in that the first threshold speed is a predetermined maximum authorized speed of the vehicle for the mode creeping walk.
  • the creeping mode is a mode of vehicle operation which increases the probability of the appearance of a reversal of the vehicle. It is then judicious, while the vehicle is operating in this creep mode, that the control device be as described, taking into account the predetermined maximum authorized speed of the vehicle for the creep mode as the first threshold speed.
  • the first threshold speed is in particular less than or equal to 15 km/h.
  • the first threshold speed is between 5 and 8 km/h, in particular equal to 7 km/h.
  • the threshold acceleration is less than 0 m/s 2 .
  • the threshold acceleration is between 0 m/s 2 and ⁇ 0.5 m/s 2 , in particular equal to ⁇ 0.2 m/s 2 .
  • the vehicle includes a parking brake device, and following this restart, the control means authorize the stopping of the combustion engine 1 if:
  • this parking brake device is actuated to brake the vehicle, or
  • the vehicle is traveling at a speed greater than a second threshold speed, and with an acceleration greater than or equal to 0 m/s 2 .
  • the second threshold speed is strictly greater than the first threshold speed.
  • the invention also relates to a vehicle comprising:
  • the combustion engine and the non-thermal driving machine configured to supply torques respectively for at least the wheel set
  • the non-thermal driving machine is an electric motor whose maximum possible torque reduced to the wheels of the wheel set for a vehicle speed between 0 and 10 km/h is less than 1250 N.m.
  • Figure 1 shows a diagram of the architecture of a hybrid vehicle for which the invention is applicable.
  • Figure 2 is a set of acceleration curves as a function of vehicle speed illustrating the difference between non-mild hybrid vehicles and mild hybrid vehicles.
  • FIG. 3 shows a timing diagram of the combustion engine restart actions according to the invention.
  • This vehicle includes a mechanical traction system, an electrical power network, and an electrical on-board network.
  • the mechanical traction system comprises:
  • the gearbox 4 further comprises:
  • a second disengageable coupling means for example a clutch, coupling the primary shaft 6 to the second end of the crankshaft 2,
  • non-thermal driving machine 9 for example a reversible electric driving machine 9
  • This third coupling means 10 is for example a gear train.
  • the non-thermal engine 9 can be coupled to a second set of wheels while the combustion engine is coupled to a first set of wheels distinct from the second, or even to the secondary shaft 7 or an intermediate shaft of the gearbox 4.
  • Figure 1 illustrates a single non-thermal driving machine 9, but this is not mandatory and one can have for example a first non-thermal driving machine 9 coupled to a front wheel set of the vehicle, the combustion engine 1 being also coupled to this same set of front wheels, and a second non-thermal driving machine 9 coupled to a set of rear wheels of the vehicle.
  • the torque at the wheel will then be the sum of each torque of the first and second non-thermal driving machine 9 multiplied by a reduction ratio bringing the torque of the non-thermal driving machine 9 to the wheel.
  • the reversible electric machine 3 is coupled to the crankshaft 2, for example to the second end of the crankshaft 2 by the first means of coupling 11 .
  • This first coupling means 11 is for example a belt transmission.
  • the reversible electric machine 3 is for example an alternator-starter making it possible to restart the combustion engine 1, that is to say a short time after a previous stoppage of the combustion engine 1, less than 10 minutes for example: oil of the combustion engine 1 is then still at a higher temperature than an ambient temperature, and under these conditions the restart is a hot start of the combustion engine 1, as opposed to a cold start of the combustion engine 1 when the oil temperature is equal to the ambient temperature.
  • the combustion engine 1 comprises a starter 12 coupled to the crankshaft 2 and able to start the combustion in particular for the cold start.
  • the electrical power network includes:
  • This electrical power network is advantageously the power network of a light hybrid vehicle, for example working at a voltage of 48V.
  • the electrical on-board network includes:
  • the current converter 14 acting as the interface between the electrical on-board network and the electrical power network by transforming, for example, the 48V voltage into a 12V voltage for the on-board network,
  • a service battery 16 for example a 12V battery
  • control devices 18 arranged so as to control the starting or stopping of the combustion engine 1, to control the reversible electric machine 3, the current converter 14, the second coupling means 5, the driving machine non-thermal 9, the motive energy storage means 13, the service battery 16.
  • This vehicle also includes a control command network, not shown, for exchanging information and commands between the control device 18 and the aforementioned organs to be controlled, or between vehicle sensors and the control device 18 .
  • This vehicle further comprises:
  • a brake control device coupled to the braking circuit of the vehicle, for example a brake pedal,
  • a vehicle speed control device for example coupled to the control device 18 which controls the combustion engine 1, or the non-thermal driving machine 9, or a combination of the two, to produce a torque at the wheels of the vehicle depending speed or torque demanded by the speed control device.
  • This vehicle speed control device is for example an accelerator pedal, or a steering wheel control.
  • This vehicle further comprises a parking brake device.
  • This parking brake device is for example a brake independent of the braking circuit of the vehicle, such as for example a handbrake comprising a lever operable by the driver and the actuation of which causes braking of a set of wheels, preferably a rear wheel set of the vehicle.
  • this parking brake can also be a system for locking the secondary shaft of gearbox 4, comprising notched jaws integral with the housing of the gearbox and closing on a toothed crown of the secondary shaft.
  • the control device 18 includes control means. These control means are for example an assembly comprising a supervision computer, and one or more specific computers coupled to the supervision computer via a data bus of the CAN type for the English acronym “Controller Area Network”. These computers include means for acquisition, processing by software instructions stored in a memory as well as the control means required to implement a method. [042] But as a variant, these computers can be grouped together in a single computer.
  • the invention will therefore propose to implement, within the vehicle, a method intended to control the restarting of the combustion engine 1 .
  • control device 18 can be produced in the form of software (or computer (or even “software”) modules )), or electronic circuits (or “hardware”), or a combination of electronic circuits and software modules.
  • the term battery will be understood throughout the text of this document to mean an assembly comprising at least one battery module containing at least one electrochemical cell, the service battery being considered equivalent to at least one module.
  • This battery optionally comprises electrical or electronic means for managing the electrical energy of this at least one module.
  • the battery block When there are several modules, they are grouped together in a housing and then form a battery block, this battery block being often designated by the English expression "battery pack", this housing generally containing a mounting interface, and terminals for connection.
  • battery pack this housing generally containing a mounting interface, and terminals for connection.
  • the word casing designating throughout the text of this document indifferently the casing of the module or of the battery block.
  • electrochemical cell will be understood throughout the text of this document to mean cells generating current by chemical reaction, for example of the lithium-ion (or Li-ion) type, of the Ni-Mh type, or Ni -Cd or even lead.
  • Hybrid vehicles generally use non-thermal drive machines, in particular electric drive machines, capable of generating a maximum torque of 2000 to 2500 Nm at the wheel, between 0 and 12 km/h, which allows the vehicle to climb slopes greater than 25% using only the power of the electric motor.
  • a maximum torque excludes these vehicles from the field of mild hybrids, whose non-thermal driving machine 9, here an electric driving machine, is generally powered by a voltage of 48V and whose maximum torque generated at the wheel is half as much for this same speed range, from 1000 to 1250 Nm, which implies potential reversals on a slope of the vehicle when it advances solely by the force of the non-thermal driving machine 9, the time for the combustion engine 1 to restart and be able to tow the vehicle.
  • Figure 2 illustrates the difference between hybrid vehicles and mild hybrid vehicles, representing the dynamic consequences on the vehicle depending on its speed.
  • the abscissa axis is the vehicle speed in Km/h
  • the ordinate axis is the maximum longitudinal acceleration, in m/s 2 , of the vehicle:
  • a first zone Z1 in which we find the characteristics of non-light hybrid vehicles, for example a maximum acceleration between 1.5 and 4.75 m/s 2 for a speed between 0 and 20 km/h,
  • zone Z2 a second zone Z2, whose maximum longitudinal accelerations are all much lower than zone Z1, characteristic of light hybrid vehicles, for example between 0.5 and 1.15 m/s 2 for a speed between 0 and 16 km/ h.
  • a combustion engine 1 restart time of 0.7 seconds time between the restart command and the instant when the engine is able to supply torque for the traction of the vehicle
  • a combustion engine 1 restart time of 0.7 seconds time between the restart command and the instant when the engine is able to supply torque for the traction of the vehicle
  • reversal of the vehicle will be understood throughout the text of this document to mean a movement of the vehicle in the opposite direction to the selected direction of travel of the vehicle: If a forward speed is selected, the reversal corresponds to a movement of the vehicle backwards and if reverse gear is selected, reversing corresponds to movement of the vehicle in forward gear.
  • Negative acceleration will be understood throughout the text of this document to mean a decrease in the speed of the vehicle moving in the selected direction of travel of the vehicle, or an increase in the speed of the vehicle moving moving in the opposite direction to that of the selected direction of travel of the vehicle.
  • the torque at the wheel, or at the wheel set, regardless of the number of driving wheels, is the sum of the torques of each non-thermal driving machine 9 multiplied by a transmission ratio between the shaft of output of each non-thermal driving machine and the shaft of one or more wheels.
  • this transmission ratio therefore includes the ratio of the shortest speed of the gearbox 4, the ratio of the third coupling means, and the ratio of a differential (not shown) whether or not integrated into the gearbox 4.
  • control device 18 illustrated in the non-limiting example of Figure 1 is configured for a vehicle, this vehicle comprising:
  • this control device 18 comprises the control means triggering the restart of the combustion engine 1, when:
  • the vehicle is traveling at a speed lower than a first threshold speed

  • the brake control device is not actuated by the driver.
  • This control device 18 comprises means for controlling the vehicle with the creep mode, and the first threshold speed is a predetermined maximum authorized speed of the vehicle for the creep mode.
  • the first threshold speed is for example less than or equal to 15 km/h. It can be between 5 and 8 km/h, in particular equal to 7 km/h as illustrated in FIG. 3.
  • the threshold acceleration is less than 0 m/s 2 .
  • the threshold acceleration is for example between 0 m/s 2 and - 0.5 m/s 2 , in particular equal to - 0.2 m/s 2 as illustrated in FIG. 3.
  • the vehicle includes the parking brake device, and following this restart, the control means authorize the stopping of the combustion engine 1 if:
  • this parking brake device is actuated to brake the vehicle, or
  • the vehicle is traveling at a speed greater than a second threshold speed, and with a positive acceleration greater than or equal to 0 m/s 2 .
  • the second threshold speed is for example greater than the first threshold speed, so as to ensure hysteresis between the restarting of the combustion engine 1 and the authorization to stop the combustion engine 1 .
  • the second threshold speed is between 103% and 150% of the first threshold speed.
  • the second threshold speed is between 103% and 115% of the first threshold speed. More precisely, the first threshold speed being 7 km/h, the second threshold speed will be for example 8 km/h.
  • This vehicle includes the control device 18.
  • the non-thermal driving machine 9 is an electric motor whose maximum possible torque reduced to the wheels of the wheel set 8 for a vehicle speed between 0 and 10 km/h is less than 1250 N.m.
  • FIG. 3 shows a timing diagram of the combustion engine restart steps according to the invention. This chronogram is divided into three sub-chronograms for greater clarity, each of these three sub-chronograms having a reference whose abscissa axis is common, and represents the time.
  • the first sub-chronogram represents an altitude curve Ci of the vehicle in meters.
  • the vehicle is going to climb a climb which begins at time ti and ends at time t 7 .
  • the altitude at time t 7 is therefore greater than the altitude at time ti. It will be noted that between instant to and ti the vehicle is moving on a horizontal surface. In addition, between time to and t 7 the brake control device is not actuated by the driver.
  • the second sub-chronogram represents curves C 2 and C 3 .
  • the y-axis is double and represents:
  • the third sub-chronogram represents curves C 4 and C 5 .
  • the y-axis is double and represents:
  • the acceleration C 3 decreases becoming negative, until reaching at time t 3 the value of ⁇ 0.2 m/s 2 .
  • This value of -0.2 m/s 2 is the threshold acceleration of this example: the driver not actuating the brake control device, the conditions according to the invention are met for, at time t 3 , restart the combustion engine 1, which is done.
  • the restart time of the combustion engine 1 corresponding to the duration between the instant t 3 and the instant t 3 bis, the speed of the vehicle C 2 continues its decrease just like the acceleration C 3 , until the instant t 4 when the speed of the vehicle C 2 becomes zero while the vehicle is:
  • control device 18 comprises for example a means for controlling preventive comfort, filtering the torque setpoint at the wheel C 4 for example by smoothing the step or crenellation of the setpoint C 4 , so that the driver, like the mechanics, does not suffer a shock. This smoothing is not shown in FIG. 3. From time t 7 , the vehicle regains a horizontal rolling zone and the speed C 2 becomes constant while the acceleration C 3 becomes zero again.
