Definitions

  • the present invention relates to the control of heat engines and gearboxes of a motor vehicle. It applies to any vehicle fitted with a petrol or diesel engine, associated with an automatic gearbox with discrete ratios or continuously variable.
  • This system uses two separate maps, making it possible respectively to deduce from the torque (or power) setpoint at the wheels and from the vehicle speed, a primary speed or a transmission ratio, and an engine torque setpoint.
  • the control system illustrated by publication US 4893 526 has the drawback of requiring information to be taken on the primary shaft of the transmission, and of being applicable only on a transmission with a continuously variable ratio.
  • the present invention aims to overcome the primary speed sensor or transmission ratio sensor, and to have a global control tool for the powertrain, usable with all types of automatic or automated transmission, with discrete ratios or with continuously variable ratio.
  • the internal combustion engine and the gear change device receive, through their respective maps, a load instruction and a transmission instruction, on the basis of the same power instruction, established from the position of the accelerator pedal.
  • the power setpoint is calculated according to a law defining the progressiveness of the accelerator pedal.
  • the invention also provides that the engine load setpoint is determined as a function of the power setpoint and the speed of movement of the vehicle.
  • FIG. 1 groups together the different functional units necessary for implementing the invention
  • the computer 1 receives from the accelerator pedal 2 information p relating to the position thereof.
  • the information p is processed in a first calculation unit 3, applying a law of progressiveness of the pedal, to establish a power setpoint P to be applied to the wheels to satisfy the driver's request.
  • the setpoint P is transmitted to a second and to a third computing unit 4, 6, respectively applying engine and gearbox maps.
  • the units 4 and 6 process the setpoint P and the vehicle movement speed information v (transmitted by the gearbox 8 in the non-limiting exemplary embodiment illustrated in FIG. 1), for transmit to the motor 7 a charge setpoint ⁇ and, at the gearbox 8, a transmission setpoint ⁇ , in the form of a transmission ratio setpoint, or primary transmission shaft speed.
  • the invention aims to control it globally.
  • the proposed method assumes the presence of a means for controlling the engine torque ⁇ , independent of the position p of the accelerator pedal, which means that the accelerator pedal is not connected by cable to the control member. of charge ⁇ .
  • a means for controlling the engine torque ⁇ independent of the position p of the accelerator pedal, which means that the accelerator pedal is not connected by cable to the control member. of charge ⁇ .
  • the throttle valve is motorized
  • a pressure injection system for example of the type " Common Rail.
  • this process is applicable with any type of automatic gearbox, with discrete or continuous reports.
  • the invention firstly provides for determining a power setpoint P for the wheels from the position information of the pedal p, according to a law defining the progressiveness of the pedal, and for exploiting it in seconds and third calculation units 4.
  • the gear change mechanism is an automatic transmission fitted with a hydrokinetic torque converter
  • the invention notably provides for possibly using in the engine calculation unit 4, two separate maps, depending on whether the torque converter is bridged or not. This provision, optional, but particularly advantageous is illustrated by Figure 2 distinguishing in this case, the exploitation the power setpoint P by one or the other of these two maps, as well as the exploitation of information on the 'bridged state or not of the converter in the calculation of the load ⁇ .
  • This figure illustrates a particular application of the invention in the case of a vehicle equipped with an electric butterfly gasoline engine and of a continuously variable transmission or CVT (Continuously Variable Transmission) provided with a bridging torque hydrokinetic converter. It highlights:
  • the overall control method of a powerplant proposed by the invention has many advantages related to its simplicity and its very wide possibilities of apphcation.
  • it does not use a gear or primary speed sensor, and that it is applicable to both a continuously variable transmission and a transmission with discreet reports.
