Definitions

  • This invention relates to vehicle transmissions which include a multi-ratio gearbox and in particular to transmissions which have an automatic ratio selection mode.
  • a vehicle transmission comprising a main drive clutch, a multi-ratio gearbox, a gear engaging mechanism for engaging the operative ratio of the gearbox, a manually operable gear selector allowing the operator to manually select the operative ratio of the gearbox when the transmission is acting in a manual mode, and an electronic control means which controls the disengagement and engagement of the drive clutch at start-up and halting of the associated vehicle and during gear changes and which also determines which gear ratio is to be selected when the transmission is acting in an automatic mode, the transmission being characterised in that the manually operable gear selector is arranged to enable the operator to override the current automatically selected ratio, and the transmission then remains in manual mode if an override is actioned until the operator switches the transmission back to its automatic mode or a predetermined time period has elapsed.
  • the operator overrides the automatically selected ratio using a steering column-mounted stalk which is moved in a first direction to change the currently operative ratio upwards and in a second direction to change the currently operative ratio downwards.
  • the stalk may also carry a manual/auto selection member to switch between the manual and automatic modes of the transmission.
  • This manual/auto selection member preferably comprises a button on the end of the stalk which switches between the manual and automatic modes on each successive depression of the button.
  • a visual display is provided which indicates whether manual or automatic mode is operative.

  • the selection of the operative ratio of the gearbox may be controlled automatically or manually.
  • a loor-mounted automatic-mode selector lever 24 operates in a gate 50 which has three positions; a 'N' position in which lever 24 is placed when it is desired to engage neutral when the vehicle is operating park in the automatic ratio selection mode (the vehicle can only be started when in neutral; an 'R' position in which the lever is placed to select reverse, and a 'D' position in which the lever is placed when it is desired that the forward drive ratio of the gearbox should be selected automatically by an electronic control unit 36 in accordance with the current operating conditions of the vehicle.
  • the position of lever 24 in gate 50 is sensed by a series of sensors (eg. micro switches and/or optical sensors) which are collectively indicated in Figure 1 at 33 and whose signal outputs Vs are fed to control unit 36.
  • gear engaging mechanism 25 which includes, for example, hydraulic rams and solenoid control valves to move selector members to engage the desired gearbox ratio.
  • gear engaging mechanism 25 includes, for example, hydraulic rams and solenoid control valves to move selector members to engage the desired gearbox ratio.
  • control unit 36 determines which ratio is most appropriate for the current vehicle operating conditions and issues appropriate ratio selection signals to gear engaging mechanism 25.
  • control unit 36 receives signals from a plurality of vehicle operating parameter sensors such as signals Ve proportional to engine speed from engine speed sensor 26. Signals Vt are received from throttle valve position sensor 30 proportional to the current throttle opening and accelerator pedal position signals Va from an accelerator position sensor 19a are also fed to control unit 36. In certain implementations of the system only one of the sensors 19a and 30 may be provided. Most commonly in such a situation it is sensor 19a which is provided.
  • Control unit 36 also receives a gear signal Vg from gear position sensor 32 which corresponds to the gear ratio currently engaged, signals Vc from slave cylinder position sensor 34, which varying with the position of the slave cylinder 22, and signals Vdp proportional to clutch driven plate speed from speed sensor 42 which actually sens s the speed of the gearbox shaft 15 (which is equal to that of a driven plate 40 or the clutch 14).

  • a flashing 'warning light (not shown) may be used and/or the instrument panel display may be arranged to flash.
  • control unit 36 also controls the engagement and disengagement of the clutch 14. This is done by the control unit 36 generating a reference signal Vr in a generator C (see figure 3) which is representative of a desired engine speed. This reference signal is compared in comparator A with the actual engine speed signal Ve from engine speed sensor 26 to produce an error signal E which is compared in comparator B with the clutch actuator position signal Vc from sensor 34 to provide a clutch engagement control signal Vce which the control unit 36 outputs to the hydraulic control 38. Operation of a control unit 36 in this general manner is described in more detail, for example in the Applicants earlier European Patents 0038113 and 0043660.
  • control unit 36 In addition to controlling the engagement and disengagement of clutch 14 the control unit 36 also controls the throttle setting via a throttle control 37 when its control logic indicates that an override of the throttle opening set by the driver's operation of the accelerator 19 is desirable.
  • the operative ratio of gearbox 12 can be selected manually via a steering column mounted control stalk 60 which is spring-biased to the central position shown in Figure 1 and which on each successive movement of stalk 60 in direction Zl (see figs 4a & 4c) to position 60a sends a signal Vs to control unit 36 to change-up one ratio in the currently operative ratio of the gearbox and on each successive movement of the stalk 60 to position 60b sends a signal Vs to change-down one ratio in the currently operative ratio.
  • stalk 60 may be movable in direction Z2 (at right angles to Zl) to positions 60c and 60d to make up and down changes respectively. If the stalk 60 is movable in both directions Zl and Z2, up changes are initiated on movements to positions 60a and 60c and down changes on movements to positions 60b and 60d.
  • Stalk 60 can be used to manually override the ratio selected by control unit 36 when in automatic mode or to normally select the operative ratios when in the manual mode.

  • the transmission control may be set-up so that if manual control mode is selected by operating button 61 appropriately (or be movement of stalk 60 to override the ratio selected in Automatic mode) the control will remain in manual mode until button 61 is pressed to invoke the automatic mode control.
  • the control may be set-up to automatically revert to automatic mode after a predetermined time period of say 10 seconds in manual mode.
  • Figure 2 illustrates in flow diagram form the mode selection procedure.
  • the control automatically assumes the automatic control mode when the vehicle ignition is switched on.
  • the control remains in automatic mode until either the stalk 60 is moved to initiate an up or down change (box B) or the button 61 is pressed to invoke manual mode (box C) .
  • the control 36 checks (see box E) that the selected ratio is appropriate for the current operating conditions (eg whether the engine is likely to overspeed or the load is too high for the selected ratio) and, if the selected ratio is deemed appropriate, actions the selected change in gearbox ratio.
