Definitions

  • the device comprises a force distribution means which distributes the longitudinal force to the rear axle calculated by one of the calculation means in two forces: a rear longitudinal force left for the left rear wheel of the vehicle, and a right rear longitudinal force for the right rear wheel of the vehicle whose values are calculated so as to satisfy the stability conditions of the vehicle and the driving situation detected.
  • FIG. 1 is a diagram of the vehicle comprising a device for controlling the saturation of the forces according to the invention
  • FIG. 2 is a flowchart of the method for controlling the saturation of the forces according to the invention
  • a hybrid vehicle shown in a particular embodiment of the invention in Figure 1, comprises a heat engine 20, mechanically coupled to the drive wheels of a front train AV of the vehicle.
  • a device 28 for controlling the saturation of the forces or torques of the drive wheels according to the invention is arranged in the vehicle.
  • I l makes it possible to vary the saturation of the force or the torque applied to the rear axle AR of the vehicle so as to compensate for any falls in torque to the wheels of the vehicle that may occur for example when changing gear.
  • the front 12 and rear 14 differentials also comprise means for distributing the drive and braking torques imposed by the device for controlling the saturation of the forces 28 and in particular for the rear axle AR.
  • FIG. 1 A particular embodiment of the device 28 for controlling the saturation of the forces of the invention is shown more precisely in FIG.
  • - vehicle dynamics and ground-link parameters longitudinal and lateral acceleration and four-wheel speeds, vehicle acceleration and overall speed, yaw rate, effort or overall driving torque, effort or torque to front and rear AR trains.
  • the detection block 44 of the rolling mode parameters makes it possible to evaluate from the engine data whether the vehicle is in the acceleration, deceleration or running phase with a load, for example, if it starts the rise of a coast, etc.
  • the estimating block 48 of the forces comprises means for measuring or estimating the forces applied to each wheel, longitudinal forces Fxav, Fxar and vertical Fzav, Fzar respectively of the front and rear axles AR, which are the orthogonal projection on an axis longitudinal and a vertical axis a total effort, Ftotale, requested by the driver, through the detection of the position of the pedals.
  • the calculation block 52 comprises means for calculating, from the driving situation, wheel forces and the speed of each wheel, a value adapted to the longitudinal force Fxar sat applied to the rear axle AR.
  • the longitudinal longitudinal force value Fxar_sat is then transmitted to the distribution block Left / Right 54 which distributes the force to the left wheel G and right D of the rear axle AR according to the driving situation. For example, if the vehicle approaches a right turn, the amount of braking on the outer wheels, the left wheels G, is greater than the inner wheels, the right wheels D, in the case of a sub-turning vehicle.
  • the distribution block 54 thus calculates a longitudinal force value for the right rear wheel, Fxar_sat_D, and a longitudinal force value for the left rear wheel Fxar_sat_G, values which depend on the driving situation.
  • the interval of the lowest values corresponds to very small values (absolute) of longitudinal force Fxav, a phenomenon which is generally referred to as a "torque hole" where the forces (or torques) on the front axle AV drop sharply when example of a change of report.
  • This saturated longitudinal force calculation technique makes it possible, depending on the driving situation, to authorize or not the compensation of a torque hole or the recovery of energy, by making the rear electric motor 24 work in current generating mode. to recharge the energy storage element 26, in the case where there would be no or very little longitudinal force, Fxav, applied to the front axle AV, where the value of the longitudinal force Fxav to the front axle AV is in the range of the lowest values.
  • the second verification means 62 controls the first calculation sub-block 68, described above, which calculates a longitudinal longitudinal force velocity Fxar_sat which satisfies the group of equations 2. The value of longitudinal force Fxar sat thus calculated is then distributed as a function of the driving situation by the distribution block 54.
  • the signals Fav and Far thus calculated or estimated are then transmitted to a control step S3 of the value of the longitudinal force Fxar to the rear axle AR and which implements the means of the first verification sub-block 60.
  • the verification step S5 checks whether the value of the longitudinal force Fxav AV forward train is in a range of the lowest values of Fxav, delimited by two threshold values, SeuiM and Seuil2.
  • Step S6 executes a command which makes it possible to calculate a saturated value of the longitudinal force Fxar_sat to the train AR which takes into account the force Fav applied to the train AV and the various parameters of the vehicle which reflect the driving situation, the condition of the roadway and the driver's will.
  • step S8 the method returns to the beginning of the program to execute step S1 again.
  • Fxar sat must respect the fact that the sum of the longitudinal forces on the front and rear traps does not exceed not a guideline of longitudinal force, Fxtotale, imposed by the driver.
  • the second criterion is that a potential of adhesion of the rear axle AR, defined as being the ratio of the longitudinal force on the vertical force on the rear axle AR is never superior (in absolute value) to a potential of adhesion of the front axle AV.
  • the calculation step S7 therefore calculates a longitudinal force to the saturated rear axle AR Fxar sat which solves the group of equations 2.
