Description

Technical Field

[0001] The present invention relates to the field of hybrid vehicles and, more particularly, to the selection of a propulsion mode for such vehicles. Background Art

[0002] A hybrid vehicle is a vehicle comprising an internal combustion engine and an electric motor, both of which are dedicated to vehicle propulsion. Thus, a user of a hybrid vehicle can choose between a thermal propulsion mode involving the internal combustion engine on the one hand and an electric propulsion mode involving the electric motor on the other.

[0003] The propulsion mode is usually selected via an automatic transmission, but a manual transmission with a gear selector can also be used. When the hot propulsion mode is selected, any movement of the gear selector by the user mechanically moves the transmission components within the transmission, such as the fork clutch or dog clutch, while the electric propulsion mode means that these transmission components are not required.

[0004] Therefore, it is necessary to use a system that allows the transmission components to move when the thermal propulsion mode is used, for example by using a detection mechanism, but ensures that these components are not driven when the electric propulsion mode is used. Summary of the Invention

[0005] The main object of the present invention is therefore a selector lever arranged in a manual gearbox of a vehicle, the selector lever comprising at least one engagement finger for engaging at least one gear of the manual gearbox, the engagement finger occupying at least a first position and a plurality of other positions, the first position being configured to allow electric propulsion of the vehicle and the plurality of other positions being configured to control the gears of the manual gearbox, the selector lever comprising means preventing control of the gears of the manual gearbox when the engagement finger is in the first position.

[0006] A manual transmission of a vehicle (e.g. a hybrid vehicle) includes a gear selector that can be operated by a user of the vehicle. Moving the gear selector results in movement of a selector lever, and more specifically movement of an engagement finger of the selector lever. The engagement finger can occupy several positions during its movement, including a first position configured to allow electric propulsion of the vehicle and a plurality of other positions configured to control the gears of the manual transmission. Thus, when the engagement finger is in the first position, the vehicle can, for example, move forward or backward using an electric propulsion mode involving an electric motor. Conversely, when the engagement finger is in any of the plurality of other positions, that is, when it controls one of the gears, the vehicle can move forward or backward using a thermal propulsion mode involving an internal combustion engine. However, it is necessary to ensure that when the engagement finger is in the first position, i.e. when the electric propulsion mode is selected, the gear of the thermal propulsion mode cannot be engaged, as this would result in movement of transmission components within the transmission, which would be incompatible with the use of the electric propulsion mode.

[0007] To this end, the selector lever has means for preventing control of the gears of the manual transmission when the engagement finger is in its first position. According to one example, the means for preventing control of the gears of the manual transmission when the engagement finger is in its first position is a mechanical device.

[0008] Such a selector lever thus makes it possible to switch safely between thermal and electric propulsion modes.

[0009] According to one feature of the invention, the selector lever comprises at least one engagement finger position sensor configured to detect at least the first position and to signal a switch of the vehicle to electric propulsion.

[0010] Thus, the position sensor can detect when the vehicle switches to electric propulsion mode and notify the vehicle or even the user of the vehicle.

[0011] According to another characteristic of the invention, the selector lever comprises a rotary support on which the engagement finger is mounted.

[0012] Thus, a change in position of the engagement finger (eg from a first position to one of a plurality of positions configured to control a gear of a manual transmission) is achieved by rotating the rotation support.

[0013] According to one feature of the invention, the means for preventing the control of the gears of the manual transmission when the engagement finger is in the first position takes the form of a sector adapted to lock a plurality of gear engagement forks arranged in the manual transmission. In this case, the forks are held in their intermediate position by the sector.

[0014] These gear engagement forks are activated when the engagement finger is in one of several positions configured to control the gears of the manual transmission; they are transmission components that participate in transmitting the torque of the internal combustion engine. To this end, they can cooperate with the engagement finger, for example, via a recess carried by the engagement finger, in which the engagement finger engages. When the engagement finger is in the first position, it cannot cooperate with the forks and transmit the torque of the internal combustion engine.

[0015] It can therefore be understood that the first position configured to allow electric propulsion corresponds to a lack of association between the engagement finger and either of the engagement forks. According to the present invention, this lack of association is ensured by a sector, which can cooperate with the engagement forks in place of the engagement fingers to lock them. Thus, depending on the propulsion mode, the sector can lock or unlock the engagement forks.

[0016] According to another feature of the invention, the engagement finger occupies a second position configured to allow electric propulsion, the first position corresponding to forward movement of the vehicle and the second position corresponding to rearward movement of the vehicle.

[0017] It will therefore be appreciated that the first position uses the motor to move the vehicle forwards, while the second position uses the motor to move the vehicle backwards.

[0018] According to one feature, the engagement finger position sensor is configured to detect the second position and signal the vehicle to switch to electric propulsion.

[0019] In the same manner as the first position, the position sensor detects when the vehicle is reversed using electric propulsion mode and notifies the vehicle, and thereby its user.

[0020] According to one feature of the invention, the engagement finger position sensor is configured to detect an engaged manual transmission gear ratio and signal the vehicle that the manual transmission is engaged.

[0021] In particular, the position sensor is thus notably configured to detect the association or lack of association between the engagement finger and the engagement fork.

[0022] According to another feature of the invention, the position sensor is a contactless sensor.

[0023] For example, the position sensor may be a Hall Effect sensor.

[0024] According to one feature of the invention, the rotary support carries a magnetic strip and the position sensor comprises a detector comprising this magnetic strip.

[0025] The position sensor detector is thus able to detect the magnetic field of the magnetic strip, which is variable on the surface of the magnetic strip. The different values of the magnetic field correspond to different positions occupied by the engagement finger, and the recognition of one of these values allows the position sensor to determine the specific position in which the engagement finger is located.

[0026] According to one feature, the ball system locks the first position and / or the second position of the engagement finger.

[0027] This ball system, like the engagement finger, is carried by the rotating support. During rotation, for the thermal propulsion mode, said ball system can bring the engagement finger into an angular relationship with one of the engagement forks, or inversely, for the electric propulsion mode, angularly offset the engagement finger relative to these engagement forks. "Angular relationship" is understood herein to mean that the engagement finger is arranged relative to one of the engagement forks so that it can cooperate with its recess.

[0028] The invention further relates to a hybrid motor vehicle comprising an internal combustion engine connected to a manual gearbox and electric motors participating in the movement of the vehicle and a selection lever as described above.

[0029] The selection lever is used to move the vehicle according to a propulsion mode involving one or the other of these electric motors.

[0030] According to one feature of the invention, the selection lever is controlled by a device for selecting the propulsion mode of the vehicle from the propulsion mode of the internal combustion engine connected to the manual gearbox and the electric propulsion mode, this propulsion mode selection device being configured to be controlled by at least one gear selector.

[0031] The invention also relates to a device for selecting the propulsion mode of a vehicle from the propulsion of an internal combustion engine connected to a manual gearbox and the propulsion by electric motors, this device comprising: a first selection profile between the gears of the manual gearbox, this first selection profile comprising at least a low gear and a high gear in the forward gears and a reverse gear in the reverse gears; a second selection profile between at least two electric propulsion modes; and a single gear selector selecting one of the gears of the manual gearbox or the electric propulsion mode, the low gear being arranged at a first end of the first selection profile and the high gear being arranged at a second end of the first selection profile, the second selection profile being arranged on the same side as the second end of the first selection profile.

[0032] The selection device according to the present invention may include an H-shaped selection grid within which shifting of the gear selector allows selection of a manual transmission gear or electric propulsion mode. This selection device may be unique within the vehicle in which it is equipped, meaning that the same selection device is used for both thermal and electric propulsion modes. A user of a vehicle equipped with the present invention can thus operate it without any additional mental effort, as all control over the propulsion mode is available by operating the same gear selector in the usual manner for a manual transmission.

[0033] For this purpose, the selection device is divided into two selection profiles, wherein the first selection profile is dedicated to the thermal propulsion mode and the second selection profile is dedicated to the electric propulsion mode. The thermal propulsion mode is connected to the manual transmission and uses the gear from the manual transmission, while the electric propulsion mode does not interact with the manual transmission to propel the vehicle.

[0034] The two selection profiles are arranged side by side in the selection device. The first selection profile includes at least one low gear (e.g., first gear) and one high gear (e.g., sixth gear in a six-speed gearbox), while the second selection profile is closer to the high gear than to the low gear. This applies to both right-hand drive and left-hand drive vehicles.

[0035] According to one feature of the invention, the gear selector moves within a first selection profile or a second selection profile.

[0036] The gear selector can be moved within a first selection profile, a second selection profile, or from one selection profile to another. Moving the gear selector in this manner allows selection of a manual transmission gear within the first selection profile or selection of an electric propulsion mode within the second selection profile.

[0037] According to another feature of the invention, the selection device comprises a fixing device which occupies a first position in which the fixing device prevents the gear selector from changing from one selection profile to another and a second position in which the fixing device allows the gear selector to change from one selection profile to another.

[0038] According to one feature of the invention, the fixed device is a trigger located on the gear selector.

[0039] In this way, switching to electric propulsion is safe. To switch the gear selector from the first selection profile to the second, the user must actuate the fixed device, which in this case is a trigger, which can be located, for example, below a knob on the gear selector. This trigger can be lifted and slid along the gear selector to switch from one selection profile to the other.

[0040] According to another feature of the invention, the gear selector allows the selection of reverse gear by actuating a fixed device.

[0041] It should be understood here that actuating the same fixed device, ie the trigger, can authorize or prohibit selection of a reverse gear within the first selection profile in addition to authorizing or prohibiting switching from one selection profile to another.

[0042] According to one feature, the reverse gear is arranged at the first end of the first selection profile.

[0043] The reverse gear is therefore located at the end of the first selection contour opposite the second selection contour.

[0044] According to one feature of the invention, the first selection profile comprises at least five slots, each slot corresponding to a forward gear of the manual gearbox.

[0045] Advantageously, the first selection profile comprises six slots corresponding to the forward gears, namely the first, second, third, fourth, fifth and sixth gears, each corresponding to a gear ratio of the transmission. In addition to these forward gears, the first selection profile comprises a slot dedicated to reverse gear.

[0046] According to another feature of the invention, the second selection profile includes a position for engaging a first electric propulsion mode corresponding to forward movement of the vehicle and a position for engaging a second electric propulsion mode corresponding to rearward movement of the vehicle.

[0047] According to one feature of the invention, the gear selector performs a selection stroke within one and / or another selection profile, a first part of which is configured to occur in a direction perpendicular or substantially perpendicular to the main extension direction of the vehicle, and a second part of which is configured to occur in a direction parallel or substantially parallel to the main extension direction of the vehicle.

[0048] The gear selector can thus be moved both within a selection profile in a first portion of its travel, in a direction perpendicular to the main direction of extension of the vehicle, and within a second portion of its travel, in a direction parallel to the main direction of extension of the vehicle. The first portion of its travel serves to switch from the first to the second selection profile and vice versa, while the second portion of its travel enables the gear selector to reach the gears of the manual transmission or the various electric propulsion modes.

[0049] According to one feature, the gears of the first selection profile and the electric propulsion modes of the second propulsion profile are arranged on both sides of a split plane, the first electric propulsion mode being arranged on one side of the split plane and the second electric propulsion mode being arranged on the other side of the split plane, and the reverse gear being arranged on the same side of the split plane as the second electric propulsion mode.

[0050] This separation plane corresponds to the portion of the selector device in which the gear selector operates in its first portion of travel; in other words, the separation plane extends along the main direction of extension of the vehicle. As previously mentioned, reverse gear is located at the first end of the first selector profile, while the electric propulsion mode is located near the second, opposite end of the first selector profile. Reverse gear and the second electric propulsion mode, corresponding to reverse travel, are both located on the same side of the separation plane. This reduces the mental burden on the selector operator, as the gear selector actuation is similar for both selector positions that allow the vehicle to reverse.

[0051] According to one feature of the invention, the engagement position of the first electric propulsion mode and the engagement position of the second electric propulsion mode are configured to be aligned along a direction parallel to a main extension direction of the vehicle, the first electric propulsion mode is configured to be arranged on the second propulsion profile toward the rear of the vehicle, and the second electric propulsion mode is configured to be arranged on the second propulsion profile toward the front of the vehicle.

[0052] In other words, the first electric propulsion mode and the second electric propulsion mode are arranged on the same selection line of the selection device on either side of the separating plane.

[0053] The invention further relates to an assembly comprising a selector lever as described above, controlled by a selector device as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The features, alternatives and various embodiments of the present invention can be combined with each other in various ways, as long as they are not mutually exclusive or incompatible. In particular, if the selection of features is sufficient to confer technical advantages and / or distinguish the present invention from the prior art, an alternative of the present invention can be envisaged, which only includes the selection of the features described below separated from the other features described.

[0065] In the figures, elements common to several figures retain the same reference numerals.

[0066] therefore, Figure 1 A manual transmission 1 is schematically shown in longitudinal section and can be integrated into, for example, a motor vehicle. This type of motor vehicle is of hybrid type and includes two propulsion devices, an internal combustion engine schematically indicated by reference numeral 2 and an electric motor not shown in the figure. It will be understood that the vehicle can be driven either by a thermal propulsion mode involving the internal combustion engine 2 or by electric propulsion involving the electric motor.

[0067] The manual transmission 1 is driven by an internal combustion engine 2. The internal combustion engine 2 carries a clutch device 4 actuated by a hydraulic cylinder 6. This hydraulic cylinder 6 can be controlled, for example, by a user of a hybrid motor vehicle equipped with the manual transmission 1 when the user actuates the clutch pedal of the hybrid motor vehicle.

[0068] The manual transmission 1 transmits torque from the internal combustion engine 2 to the wheels of the vehicle. More specifically, this torque is notably transmitted to a primary shaft 8 and a secondary shaft 10. The primary shaft 8 and the secondary shaft 10 are centered around a first pivot axis Y1 and a second pivot axis Y2, respectively.

[0069] The manual gearbox 1 comprises several gears, in this case first, second, third, fourth, fifth, sixth and reverse gears, which move the hybrid motor vehicle backwards, while the other gears move the hybrid motor vehicle forwards.

[0070] To this end, mainshaft 8 carries fixed pinions 12 and 14, with the first fixed pinion 12 being used for first gear and the second fixed pinion 14 being used for second gear. Mainshaft 8 also carries four idler pinions, with a first idler pinion 16 being used for third gear, a second idler pinion 18 being used for fourth gear, a third idler pinion 20 being used for fifth gear, and a fourth idler pinion 22 being used for sixth gear. These pinions 12, 14, 16, 18, 20, 22 are designed to mate with the teeth of countershaft 10. More specifically, they mate with idler gears 24 and 26, including a first idler gear 24 for first gear and a second idler gear 26 for second gear, and with fixed gears 28, 30, 32, and 34, including a first fixed gear 28 for third gear, a second fixed gear 30 for fourth gear, a third fixed gear 32 for fifth gear, and a fourth fixed gear 34 for sixth gear.

[0071] Reverse gear can be engaged via a tertiary shaft 36 separated from the main shaft 8 and the secondary shaft 10 , wherein the pivot axis Z is parallel to the first pivot axis Y1 and the second pivot axis Y2 . This tertiary shaft 36 comprises a pinion 38 designed to cooperate with the idler gear 24 of the secondary shaft 10 .

[0072] Furthermore, the layshaft 10 and the tertiary shaft 36 each have a gear 40, 42 adapted to cooperate with a differential ring gear 44. This differential ring gear 44 is housed in a housing 46 which also contains means 48 for distributing torque to the wheels of the hybrid motor vehicle.

[0073] The various gears of the manual transmission 1 are selected by means of a selector lever 50, which will be referred to as Figures 2 to 8 1 is described. The selector lever 50 is connected to a gear selector 51 that can be actuated by a user of the hybrid motor vehicle. The gear selector 51 cooperates with the selector lever 50 via a first rotational lever 51a and a second translational lever 51b to enable a selection finger 54 to be rotated and translated sequentially along the rotation axis X. The gear selector 51 is thus involved in selecting a gear of the manual transmission 1 for thermal propulsion of the hybrid motor vehicle, but it can also be involved in selecting electric propulsion.

[0074] The selector lever 50 includes a rotating support 52, here a tubular element, which pivots about a rotation axis X parallel to the pivot axes Y1, Y2, and the pivot axis Z. The rotating support 52 is also capable of translational movement along the rotation axis X. The rotating support 52 of the selector lever 50 carries an engagement finger 54, also a tubular element. The engagement finger 54 is thus capable of rotation and / or translation relative to the rotation axis X. This movement allows the engagement finger 54 to engage with a gear engagement fork of the manual transmission 1, at least a portion of which is radially aligned in a plane perpendicular to the rotation axis X, the pivot axes Y1, Y2, and the pivot axis Z. Depending on the various positions of the engagement finger 54 (which will be described in more detail later), these engagement forks include a first engagement fork 56 corresponding to reverse gear, a second engagement fork 58 corresponding to first and second gears, a third engagement fork 60 corresponding to third and fourth gears, and a fourth engagement fork 62 corresponding to fifth and sixth gears. “Matched” is understood to mean that the engagement finger 54 can engage in the control elements of these engagement forks 56 , 58 , 60 , 62 , thus ultimately transmitting the torque from the internal combustion engine 2 .

[0075] As mentioned above, in the case of a hybrid motor vehicle, propulsion can be provided by the internal combustion engine 2 and the manual transmission 1, or by the electric motor. This type of electric motor propulsion means that the torque of the internal combustion engine 2 is not transmitted to the wheels of the vehicle. To this end, the engagement finger 54 is able to occupy at least one position in which it does not engage with any of the engagement forks 56, 58, 60, 62; this position corresponds to the electric propulsion mode and, as Figure 2 and Figure 3 exemplified.

[0076] It can thus be understood that, in addition to selecting the gears of the manual gearbox 1, the selector lever 50 makes it possible, by moving the engagement finger 54, to select between a propulsion mode involving the internal combustion engine 2 on the one hand and a propulsion mode involving the electric motor on the other hand. The gear selector 51 can thus control a device 53 for selecting the vehicle propulsion mode from a thermal propulsion mode via the internal combustion engine 2 connected to the manual gearbox 1 and an electric propulsion mode via the electric motor. Such a selection device 53 can, for example, correspond to an H-shaped grid within which actuation of the gear selector 51 results in a movement of the engagement finger 54 in the manual gearbox 1. This selection device 53 will be described later in conjunction with the Figure 9 Provide a description.

[0077] therefore, Figure 2 and Figure 31 shows a position of the engagement finger 54 configured to enable electric propulsion of the hybrid motor vehicle. This position of the engagement finger 54 may be a first angular position 64 corresponding to forward movement of the hybrid motor vehicle by electric propulsion, or a second angular position 66 corresponding to rearward movement of the vehicle by electric propulsion. It will therefore be understood that the first angular position 64 uses the electric motor to move the hybrid motor vehicle forward, while the second angular position 66 uses the electric motor to move the vehicle rearward. Such angular positions 64, 66 are Figure 4 , which shows a cross-sectional view of a portion of the selector lever 50. In this figure, the engagement finger 54 is shown both in its first angular position 64 and in its second angular position 56, but it will be understood that during operation of the selector lever 50, the engagement finger 54 can only occupy one of these angular positions 64, 66 at a time.

[0078] The first angular position 64 and the second angular position 66 of the engagement finger 54 correspond to a lack of cooperation between the engagement finger 54 and any engagement fork 56, 58, 60, 62. When the engagement finger 54 is in the first angular position 64 or the second angular position 66, the torque from the internal combustion engine 2 is therefore not transmitted to the wheels via the manual transmission 1.

[0079] Conversely, when the engagement finger 54 cooperates with one of the engagement forks 56 , 58 , 60 , 62 , torque from the internal combustion engine 2 may be transferred. Figure 5 A manual gearbox 1 is shown with an engagement finger 54 cooperating with a first engagement fork 56, Figure 6 The engagement finger 54 is shown cooperating with the second engagement fork 58, Figure 7 The engagement finger 54 is shown cooperating with the third engagement fork 60, and Figure 8 The engagement finger 54 is shown engaged with the fourth engagement fork 62. Thus, the engagement finger 54 is in a third angular position 68 when engaged with the first engagement fork 56, a fourth angular position 70 when engaged with the second engagement fork 58, a fifth angular position 72 when engaged with the third engagement fork 60, and a sixth angular position 74 when engaged with the fourth engagement fork 62.

[0080] like Figure 5 As shown, when the engagement finger 54 is in the third angular position 68 , it therefore cooperates with the first engagement fork 56 to rotate the tertiary shaft 36 along the pivot axis Z, which in turn drives the differential ring gear 44 so as to transmit torque to the wheels of the hybrid motor vehicle via the torque distribution mechanism 48 .

[0081] Similarly, when the engagement finger 54 is in one of the fourth angular position 70, the fifth angular position 72 or the sixth angular position 74, it cooperates with the second engagement fork 58, the third engagement fork 60 or the fourth engagement fork 62, respectively, so as to rotate the main shaft 8 about the first pivot axis Y1 or the secondary shaft 10 about the second pivot axis Y2, which in turn drives the differential ring gear 44 to transmit torque to the wheels of the hybrid motor vehicle.

[0082] According to the invention, in order to ensure that a gear of the manual gearbox 1 cannot be engaged when the engagement finger 54 is in one of the angular positions 64 or 66 corresponding to the electric propulsion mode, the selector lever 50 comprises means that prevent the control of one of these gears when the engagement finger 54 is in the first angular position 64 or in the second angular position 66. Such means in particular allow the hybrid motor vehicle to be safe in each of the propulsion modes with respect to the other.

[0083] The means for preventing control of one of the gears of the manual transmission 1 when the engagement finger 54 is in the first angular position 64 or in the second angular position 66 may, for example, take the form of at least one sector 76 corresponding to a substantially flat disc portion. Figures 2 to 8 This sector 76 can be seen in the figure and is supported by a rotating element 78. Similar to the rotating support 52, such a rotating element 78 can rotate about the axis of rotation X, but differs from it in that its translation about the axis of rotation X is prevented. According to the invention, the sector 76 is suitable for locking the engagement forks 56, 58, 60, 62 of the manual gearbox 1 by rotating about this axis of rotation X, that is to say it is able to cooperate with said forks instead of the engagement fingers 54 when said engagement fingers are in their first angular position 64 or in their second angular position 66. In other words, depending on the propulsion mode of the hybrid motor vehicle, the sector 76 can lock or unlock the engagement forks 56, 58, 60, 62. The locking of these engagement forks 56, 58, 60, 62 of the manual gearbox 1 can be carried out in particular in Figure 4 , corresponds to the middle position of these forks.

[0084] Switching from the first angular position 64 to the second angular position 66 of the engagement finger 54 and vice versa is ensured by translating the rotary support 52 about the rotation axis X. Furthermore, switching from one angular position 68 , 70 , 72 , 74 of the engagement finger 54 to another angular position corresponding to a gear change of the manual transmission 1 is ensured by rotating the rotary support 52 about this rotation axis X.

[0085] The position of the engagement finger 54 can be locked by a ball system 80, which is particularly Figure 2 The ball system 80 comprises ball ramps 82 carried by the rotating support 52, such ball ramps 82 being able to interact with balls 84 carried by the rotating element 78. This interaction between such ball ramps 82 and the balls 84 stabilizes the rotating support 52 and thus locks the engagement fingers 54 in one position.

[0086] The position occupied by the engagement finger 54 can be detected by a position sensor 86. Such a position sensor 86 is therefore configured to detect at least the first angular position 64 and the second angular position 66 corresponding to the electric propulsion mode, so as to be able to inform the hybrid vehicle thereof and, accordingly, to use the sector 76 to lock the engagement forks 56, 58, 60, 62 accordingly. The position sensor 86 can further be configured to detect the engagement of a gear of the manual transmission 1, i.e., the cooperation between the engagement finger 54 and any one of the engagement forks 56, 58, 60, 62, and to inform the hybrid vehicle of the use of the hot propulsion mode and the engaged gear. It can therefore be understood that the position sensor 86 is configured to detect the cooperation or lack of cooperation between the engagement finger 54 and the engagement forks 56, 58, 60, 62.

[0087] To this end, the rotating support 52 carries a magnetic strip 88, the magnetic field of which can be detected by a detector 90 of the position sensor 86. The position sensor 86 thus comprises both a magnetic strip 88 and a detector 90 which can for example involve a contactless sensor such as a Hall effect sensor.

[0088] Because the position sensor 86 must be able to detect several positions of the engagement finger 54, the magnetic strip 88 does not have a uniform magnetic field across its entire surface. Each position of the engagement finger 54 is therefore associated with a different magnetic field value. Therefore, based on the detected magnetic field value, the detector 90 is able to determine the position of the engagement finger 54.

[0089] As already mentioned, Figure 9Actuation of the gear selector 51 within the illustrated selection device 53 causes movement of an engagement finger 54 in the manual transmission 1. The selection device 53 has a first selection profile 55 between different gears corresponding to the gears of the manual transmission 1, and a second selection profile 57 between at least two electric propulsion modes. The gear selector 51 is movable within each of the selection profiles 55 and 57. The first selection profile 55 is dedicated to the hot propulsion mode and is therefore connected to the manual transmission 1; thus, it engages with a respective gear of the manual transmission 1. To this end, the first selection profile 55 includes seven slots, each corresponding to a gear of the manual transmission 1. The seven slots include six slots 59, 61, 63, 65, 67, and 69 for forward gears, and one slot 71 for reverse gear 93. The first slot 59, corresponding to the low gear 89, is arranged at a first end 73 of the first selection profile 55, while the sixth slot 69, corresponding to the high gear 91, is arranged at a second end 75 of the first selection profile 55. A seventh slot 71 , which corresponds to a reverse gear 93 , is arranged at a first end 73 of the first selection contour 55 .

[0090] The second selection profile 57 is dedicated to the electric propulsion mode. This second selection profile 57 is arranged next to the first selection profile 55, near its second end 75, for example next to the right side of the first selection profile 55. The second selection profile 57 comprises two slots 77, 79, each corresponding to an electric propulsion mode, wherein the eighth slot 77 is used to engage the first electric propulsion mode and the ninth slot 79 is used to engage the second electric propulsion mode.

[0091] like Figure 9 As shown, the slots 59, 61, 63, 65, 67, 69, 71, 77, 79 of the selection profiles 55, 57 are distributed relative to a separation plane 81, which extends perpendicularly to the main extension direction A of the hybrid motor vehicle. The first slot 59 of the first gear, the third slot 63 of the third gear, the fifth slot 67 of the fifth gear, the seventh slot 71 of the reverse gear 93, and the ninth slot 79 of the second electric propulsion mode are arranged on a first side 83 of the separation plane 81, while the second slot 61 of the second gear, the fourth slot 65 of the fourth gear, the sixth slot 69 of the sixth gear, and the eighth slot 77 of the first electric propulsion mode are arranged on a second side 85 of the separation plane 81.

[0092] Thus, it will be noted that the slots 71 and 79 for the reverse gear 93 and the second electric propulsion mode corresponding to rearward movement of the hybrid motor vehicle are arranged on the same side of the separation plane 81 , here the first side 83 .

[0093] Neither the switching from the first selection profile 55 to the second selection profile 57 nor the switching within the first selection profile 55 is freely done. It is to be understood that in this context such switching requires the user to operate on the selection device 53. This includes a securing means which in a first position prevents the gear selector 51 from moving from one selection profile 55, 57 to the other selection profile and also prevents the gear selector 51 from moving to the seventh slot 71 of the reverse gear position 93. Conversely, in a second position of the securing means both movements are allowed. The securing means can for example be a trigger 87, as Figure 9 The trigger 87 is schematically shown in two positions 87A and 87B, each of which corresponds to a point on the selection device 53 at which a shift from a first position to a second position is required in order to allow the movement of the gear selector 51. Thus, a first slot 87A for the trigger 87 is shown at the first end 73 of the first selection profile 55 for switching the gear selector 51 to the seventh slot 71 of the reverse gear 93, a second slot 87B for the trigger 87 is shown near the second end 75 of the first selection profile 55 for switching the gear selector 51 to the eighth slot 77 and the ninth slot 79 corresponding to the two electric propulsion modes. It is to be understood, however, that this is merely a schematic representation and that a single trigger 87 is arranged on the gear selector 51.

[0094] The present invention thus proposes a selection lever which involves a selection between a thermal propulsion mode and an electric propulsion mode, the selection lever comprising a means which ensures that the thermal propulsion mode cannot be engaged when the electric propulsion mode is selected.

[0095] The present invention is however not limited to the means and configurations described and shown herein and extends equally to any equivalent means and configurations and to any technically operable combination of these means.
