[0025] exist Figures 1 to 4 In the accompanying drawings, reference numeral 1 is used to generally indicate a motor vehicle according to a first embodiment of the invention. Preferably, but not necessarily, the motor vehicle 1 is an electric or hybrid vehicle.

[0026] Motor vehicle 1 includes ( Figure 1 ):

[0027] - Frame 2, which includes a passenger compartment 3 configured to accommodate the driver and possible passengers;

[0028] - Multiple wheels 4 (only two are shown in dashed lines), each wheel capable of rotating relative to the frame 2 about a corresponding axis of rotation A and a corresponding steering axis; and

[0029] - Parking brake 5, which is known in itself and is shown only schematically.

[0030] The motor vehicle 1 also includes an electric motor 8 operably connected to at least some of the wheels 4.

[0031] Inside the passenger compartment 3, the vehicle 1 also includes a steering wheel 7, which is located specifically at the driver's seat and is capable of rotating about a steering wheel axis. The steering wheel 7 has a known function of steering the vehicle 1.

[0032] The steering wheel 7 is preferably configured as described in the Italian patent application IT1022000018495 filed by the applicant on September 12, 2022.

[0033] More specifically, the motor vehicle 1 includes a known steering device, not shown herein, and is configured to steer at least some of the wheels 4 about a corresponding steering axis in response to rotation of the steering wheel 7 about the steering wheel axis and in a manner corresponding to the angle of rotation of the steering wheel 7 about the steering wheel axis.

[0034] Preferably, the vehicle 1 also includes a user interface 6 within the passenger compartment 3, such as a control panel including a touchscreen. In particular, the user interface 6 is located at the dashboard of the vehicle 1.

[0035] The motor vehicle 1 also includes a command device 10 configured to select one or more functions of the motor vehicle 1 to be controlled or enabled.

[0036] Advantageously, the command device 10 includes ( Figure 2 and Figure 3 ):

[0037] - Base 11, which is configured to be fixed in the passenger compartment 3 and includes guide 12;

[0038] - A movable selector 13 that can move along the guide 12 between multiple positions associated with corresponding functions of the motor vehicle 1 to control and / or enable those functions.

[0039] Command device 10 also includes a transducer 50 configured to detect or indicate the amount of movement of the movable selector 13 relative to the guide 12 or the amount of position of the movable selector 13 relative to the guide 12. Figure 1 Transducer 50 is also configured to generate a signal corresponding to the detected quantity.

[0040] Command device 10 also includes an electronic control unit 51 operably connected to transducer 50. Figure 1 The electronic control unit 51 is configured to extract information related to the movement or position of the movable selector 13 relative to the guide 12 from the signal generated by the transducer 50, and to command, control, or enable corresponding functions of the motor vehicle 1 based on this information. Specifically, the electronic control unit 51 is configured to control or enable functions of the motor vehicle 1 corresponding to the detected and / or determined position of the movable selector 13 relative to the guide 12.

[0041] The fact that the electronic control unit 51 is configured to enable the functions of the motor vehicle 1 means that the electronic control unit 51 controls the activation and / or movement of one or more components of the motor vehicle 1 and their possible coordination in order to perform the functions.

[0042] like Figure 2 and Figure 3 As shown, the movable selector 13 includes:

[0043] - An axle 30 extending in the direction Z, perpendicular to the ground on which the wheel 4 rests; and

[0044] - Knob 31 integrated with shaft 30.

[0045] In detail, the shaft 30 includes two ends 30a and 30b that are opposite to each other along the direction Z. More specifically, the shaft 30 engages the guide 12 on the end 30a side, and the knob 31 is connected to the shaft 30 on the end 30b side.

[0046] In the non-limiting embodiment shown, considering a cross-sectional plane orthogonal to direction Z, the shaft 30 has a circular cross-section. Furthermore, preferably, the cross-section of the shaft 30 has a constant extension along direction Z.

[0047] Additionally, in the non-limiting embodiment shown, the knob 31 has a spherical or substantially spherical shape. In particular, the knob 31 includes a surface 32 that can be touched and / or gripped by a user of the motor vehicle 1.

[0048] The vehicle 1 can also be defined with directions X and Y, which are orthogonal to each other and to direction Z. Preferably, but not necessarily, direction X coincides with the longitudinal extension direction of the vehicle 1. Figure 1 ).

[0049] like Figure 2 and Figure 3 As shown, the guide 12 includes:

[0050] - Extension segment 14 extending along direction X;

[0051] - Also extending along direction X and spaced apart from extension segment 14 along direction Y;

[0052] - Extension segment 16 extending from extension segment 14 to extension segment 15 along direction Y;

[0053] - An extension segment 17 extending along direction X and spaced apart from extension segment 15 along direction Y; and

[0054] - Extension segment 18 extends from extension segment 15 to extension segment 17 along the direction Y.

[0055] Extension segments 14, 15, and 17 include corresponding ends 14a, 14b, 15a, 15b, 17a, and 17b that are opposite each other along the direction X. Each end 14a, 14b, 15a, 15b, 17a, and 17b is associated with a corresponding function of the motor vehicle 1 to be controlled or activated, and the movable selector 13 can be positioned at one of the ends 14a, 14b, 15a, 15b, 17a, and 17b to select the corresponding function.

[0056] Specifically, extension segments 14, 15, 16, 17, and 18 are straight and include corresponding openings adjacent to each other obtained in the base 11. In the illustrated embodiment, the openings defining extension segments 14, 15, 16, 17, and 18 have a rectangular shape.

[0057] More specifically, the base 11 includes a surface 110 facing the movable selector 13. Openings of the extension sections 14, 15, 16, 17, and 18 are obtained at the surface 110. Furthermore, preferably, the surface 110 is flat.

[0058] More specifically, extension segment 16 extends along direction X at the midpoint (particularly the central position) between extension segments 14 and 15; similarly, extension segment 18 extends along direction X at the midpoint (particularly the central position) between extension segments 15 and 17. Furthermore, extension segments 16 and 18 are preferably aligned with each other.

[0059] The fact that the movable selector 13 is located at one end 14a, 14b, 15a, 15b, 17a, 17b means that the movable selector 13 is in contact with, close to, or located in the space between the extension segment 16 or 18 and the end along the direction X.

[0060] In the illustrated embodiment, the extension of extension segments 14, 15, and 17 along the X direction is the same for all extension segments 14, 15, and 17. Similarly, the extension of extension segments 16 and 18 along the Y direction is the same for both extension segments 16 and 18.

[0061] In other words, the guide 12 defines a grid in the base 11.

[0062] As a non-limiting example, the six ends 14a, 14b, 15a, 15b, 17a, and 17b are associated with the following functions of the motor vehicle 1:

[0063] - Movement of motor vehicle 1 in the forward direction F (“drive” function);

[0064] - Activation of parking brake 5 (“parking function”);

[0065] - Different wheels 4 are supplied with different amounts of torque through dynamic traction control ("torque vector control" or "torque steering" function).

[0066] - Based on the angle of the steering wheel 7 around the steering wheel axis, at least some of the wheels 4 are turned around the corresponding steering axis ("normal steering" function). In particular, according to this function, the steering of the motor vehicle 1 is not (only) achieved by supplying different amounts of torque to the wheels 4 along the corresponding axis of rotation A;

[0067] - Movement of a motor vehicle in the opposite direction to the forward direction F ("reverse" function);

[0068] - Starting of motor vehicle 1 from a stationary state in which motor vehicle 1 is stationary relative to a fixed reference frame (“start control function”).

[0069] - Neutral or neutral simulator (“neutral” function). In this mode, electric motor 8 does not supply torque to wheel 4;

[0070] - Dynamic braking control.

[0071] Preferably, the neutral function is associated with extension sections 16 and / or 18.

[0072] Furthermore, preferably, the control device 13 is configured to move along the guide 12 such that the shaft 30 remains constantly parallel or substantially parallel to the direction Z.

[0073] Advantageously, surface 32 includes region 33, and knob 31 also includes tactile sensor 52 (only when...). Figure 4 (Illustrated schematically) The tactile sensor is configured to detect a user's touch at least in region 33 and generate a signal indicating the touch.

[0074] The electronic control unit 51 is operatively connected to the touch sensor 52 and is configured to control two operating parameters of the motor vehicle 1 based on signals received from the touch sensor 52. Specifically, the electronic control unit 51 is configured to extract information related to a user's touch on the surface 32 from the signals generated by the touch sensor 52 and thus command changes to the operating parameters.

[0075] Preferably, the tactile sensor 52 is capacitive.

[0076] In detail, the electronic control unit 51 is configured to ( Figure 4 ):

[0077] - When the tactile sensor 52 detects a touch along the first direction J, the first parameter is controlled;

[0078] - When the tactile sensor 52 detects a touch along a second direction K that is transverse to the first direction J, the second parameter is controlled.

[0079] More specifically, the electronic control unit 51 is configured to increase the value of a first parameter when the touch sensor 52 detects a touch along the first direction J and in a first sense, and to decrease the value of the first parameter when the touch sensor 52 detects a touch along the first direction J and in a second sense, opposite to the first sense. Similarly, the electronic control unit 51 is configured to increase the value of a second parameter when the touch sensor 52 detects a touch along the second direction K and in a third sense, and to decrease the value of the second parameter when the touch sensor 52 detects a touch along the second direction K and in a fourth sense, opposite to the third sense.

[0080] Preferably, region 33 has the shape of a spherical cap and is located at the top of knob 31 along direction Z, i.e. on the side opposite to shaft 30.

[0081] Furthermore, preferably, the user's touch on the knob 31 to control the first and second parameters is performed by the user's hand, for example by the thumb.

[0082] The command device 10 also includes a selector 53, which is operatively connected to the electronic control unit 51 and can selectively switch between a first state and a second state. Specifically, in the first state, the selector 53 is configured to deactivate the knob 31, i.e., deactivate at least one of the electronic control unit 51 and the tactile sensor 52; in the second state, the selector 53 is configured to enable the knob 31 or keep the knob 31 enabled, i.e., enable the electronic control unit 51 and the tactile sensor 52 or keep the electronic control unit 51 and the tactile sensor 52 enabled.

[0083] In other words, the electronic control unit 51 is configured to allow control of operating parameters based on the user's touch on the area 33 when the selector 53 is in the first state.

[0084] Selector 53 includes a capacitive button. Preferably, selector 53 includes an illumination device configured to illuminate when selector 53 is in a first state and turn off when selector 53 is in a second state, or to emit light of a first color (e.g., green) when selector 53 is in the first state and to emit light of a second color (e.g., red) when selector 53 is in the second state.

[0085] Alternatively, selector 53 includes a mechanical button configured to present a first position associated with a first state and a second position associated with a second state.

[0086] In detail, selector 53 is located at knob 31. More specifically, selector 53 is located at surface 32. Specifically, selector 53 is located at the maximum circumference of surface 32 along direction Z. Therefore, selector 53 is inserted between shaft 30 and region 33 along direction Z.

[0087] Preferably, the selector 53 is configured to move between a first state and a second state due to contact with the user's hand (e.g., with the index finger of the hand).

[0088] exist Figure 4 In the non-limiting embodiment shown, the selector 53 includes a circular or substantially circular periphery 54 that defines it relative to the rest of the surface 32.

[0089] Preferably, the parameters controlled by knob 31 can be selected by the user, that is, they can be selected from a number of controllable parameters.

[0090] In detail, selector 53 can be selectively positioned in multiple third states, each third state being associated with a different parameter or parameter pair to be controlled among multiple controllable parameters. In other words, selector 53 is configured to allow the selection of the parameter to be controlled among the controllable parameters by means of knob 31, depending on the third state to which it transitions.

[0091] Alternatively or additionally, the parameters that can be controlled by the user via knob 31 are related to one or more functions that can be selected via movable selector 13. In other words, the parameters that can be controlled by knob 31 vary depending on the position of movable selector 13 relative to guide 12.

[0092] Alternatively or additionally, parameters that can be controlled by the user via knob 31 can be selected via user interface 6. Furthermore, user interface 6 is preferably configured to display information associated with the values ​​of the parameters controlled by knob 31, for example, in the form of bar indicators, numerical values, and / or Cartesian graphs. Preferably, user interface 6 is configured to display a Cartesian graph, wherein the value of the first parameter is associated with the horizontal axis, and the value of the second parameter is associated with the vertical axis.

[0093] For example, the first parameter is related to or consistent with the steering gain. In other words, by changing the first parameter, the degree of steering of the wheel 4 around the corresponding steering axis is changed when the steering wheel 7 is rotated by the same angle around the steering wheel axis. The second parameter is related to or consistent with the torque gain. In other words, by changing the second parameter, the maximum amount of driving torque transmitted to the wheel 4 can be changed.

[0094] Alternatively, still for example, the first and second parameters are associated with the distribution of driving or braking torque between wheels 4.

[0095] The operation of motor vehicle 1 will be described below.

[0096] In use, the user controls multiple functions of the motor vehicle 1 by moving the movable selector 13 relative to the guide 12 between the various ends 14a, 14b, 15a, 15b, 17a, 17b and the extension sections 16 and 18. The electronic control unit 51 receives information from the transducer 50 relating to the movement or position of the movable selector 13 relative to the guide 12, and thus commands the activation of the functions of the motor vehicle 1 associated with the ends 14a, 14b, 15a, 15b, 17a, 17b or the extension sections 16, 18 where the movable selector 13 is positioned.

[0097] For example, in order to move the movable selector 13 from end 14b ( Figure 2 Move to end 15b ( Figure 3 It is necessary to translate the movable selector 13 parallel to direction X toward end 14a and stop it at extension section 16. Subsequently, the movable selector 13 needs to engage extension section 16 and slide along it toward extension section 15. Finally, once extension section 15 is engaged, the movable selector 13 must slide parallel to direction X toward end 15b.

[0098] At the same time, the user can change the values ​​of two parameters of the motor vehicle 1 by means of knob 31.

[0099] First, the user presses the selector 53 to switch it to the first state, and then activates the knob 31 by touching the surface 32 of the knob 31. Specifically, the first parameter is changed by sliding the finger along direction J; the second parameter is changed by sliding the finger along direction K. The electronic control unit 51 receives information from the tactile sensor 52 related to the user's touch on the surface 32, and therefore commands the change of operating parameters.

[0100] Users can select parameters that can be controlled by knob 31 by pressing selector 53 several times to switch it to the third state, and / or by moving movable selector 13 relative to guide 12, and / or by selecting these parameters through user interface 6.

[0101] To disable parameter control using knob 31, the user presses selector 53 until it switches to the second state.

[0102] refer to Figure 5Figures 6a and 6b, wherein the numeral 1' denotes a motor vehicle according to a second embodiment of the invention. Motor vehicle 1' is similar to motor vehicle 1 and will be described below only in those aspects that distinguish the former from the latter; where possible, the same reference numerals will be used to indicate motor vehicle 1; similar or equivalent parts of 1'.

[0103] The difference between motor vehicle 1' and motor vehicle 1 is that it includes a command device 10' instead of command device 10. Command device 10' is similar to command device 10 and will be described below only in those aspects that distinguish the former from the latter; where possible, the same or equivalent parts of command devices 10 and 10' will be indicated by the same reference numerals.

[0104] The command device 10' differs from the command device 10 in that it includes a plurality of selectors 20a', 20b', 20c', 20d', 20e', and 20f' that are movable relative to the grid 12. Specifically, the selectors 20a', 20b', 20c', 20d', 20e', and 20f' can slide relative to the grid 12 along the direction X.

[0105] The command device 10' includes two selectors 20a', 20b', 20c', 20d', 20e', and 20f' at each extension segment 14, 15, and 17. More specifically, the selectors 20a', 20b', 20c', 20d', 20e', and 20f' are located along the direction X in the space between the extension segment 16 or 18 and the ends 14a, 14b, 15a, 15b, 17a, and 17b.

[0106] Each selector 20a', 20b', 20c', 20d', 20e', 20f' can be set to an enabled or disabled state. Specifically, when selectors 20a', 20b', 20c', 20d', 20e', 20f' are enabled, the function of the motor vehicle 1' associated with the corresponding terminals 14a, 14b, 15a, 15b, 17a, 17b is selected and / or enabled; when selectors 20a', 20b', 20c', 20d', 20e', 20f' are disabled, the function of the motor vehicle 1' associated with the corresponding terminals 14a, 14b, 15a, 15b, 17a, 17b is deselected and / or disabled.

[0107] Additionally, when selectors 20a', 20b', 20c', 20d', 20e', and 20f' are in the enabled state, they are positioned close to their respective ends 14a, 14b, 15a, 15b, 17a, 17b, 17b, and 17b, respectively, wherein the distance along direction X between selectors 20a', 20b', 20c', 20d', 20e', and 20f' and their respective ends 14a, 14b, 15a, 15b, 15b, 17a, and 17b is equal to a first value; When selectors 20a', 20b', 20c', 20d', 20e', and 20f' are in a deactivated state, they are positioned spaced apart from their corresponding ends 14a, 14b, 15a, 15b, 17a, 17b, and 17b, respectively. The distance along direction X between selectors 20a', 20b', 20c', 20d', 20e', and 20f' and their corresponding ends 14a, 14b, 15a, 15b, 17a, and 17b is equal to a second value, which is greater than a first value. Specifically, the first value can be zero.

[0108] For example, Figure 5 and Figure 6B Selector 20b', which is enabled, and the remaining selectors 20a', 20c', 20d', 20e', and 20f', which are disabled respectively, are shown.

[0109] In the illustrated embodiment, the base 11 includes a plurality of guide surfaces 11a', and the selectors 20a', 20b', 20c', 20d', 20e', and 20f' include corresponding slider elements, each slider element being configured to contact and engage with the corresponding guide surface 11a' (Figures 6a and 6b).

[0110] In detail, the guide surface 11a' is flat and inclined relative to the plane defined by the X and Y directions, and each slider element of the selectors 20a', 20b', 20c', 20d', 20e', and 20f' includes a corresponding flat surface inclined relative to the same plane defined by the X and Y directions.

[0111] More specifically, in the sense of orientation from extension segments 16, 18 to ends 14b, 15b and 17b, parallel to direction X, the distance between the point of guide surface 11a' and surface 110 gradually decreases along direction Z; similarly, in the sense of orientation from extension segments 16, 18 to ends 14a, 15a and 17a, parallel to direction X, the distance between the point of guide surface 11a' and surface 110 gradually decreases along direction Z (Figs. 6a and 6b).

[0112] More specifically, the guide surface 11a' is located on the side of the surface 110 facing away from the knob 31 along the Z direction.

[0113] As shown in Figures 6a and 6b, preferably, when selectors 20a', 20b', 20c', 20d', 20e', and 20f' are in the enabled configuration, they protrude relative to surface 110 along direction Z.

[0114] Each selector 20a', 20b', 20c', 20d', 20e', and 20f' is configured to engage with the movable selector 13. Specifically, each selector 20a', 20b', 20c', 20d', 20e', and 20f' is configured to move from a deactivated state to an enabled state due to movement of the movable selector 13 relative to the guide 12. Specifically, the movable selector 13 is configured to drag selectors 20a', 20b', 20c', 20d', 20e', and 20f' along the X direction relative to the corresponding guide surface 11a'.

[0115] The command device 10' also includes a plurality of actuators 56', each actuator being configured to automatically move a corresponding selector 20a', 20b', 20c', 20d', 20e', and 20f' between a corresponding enable state and a disable state, and being operatively connected to the electronic control unit 51'. For example, the actuators 56' are electromechanical actuators.

[0116] The electronic control unit 51' is configured as follows:

[0117] - Whether storage selectors 20a', 20b', 20c', 20d', 20e' and 20f' are in their respective enabled or disabled states;

[0118] - Detect and store when selectors 20a', 20b', 20c', 20d', 20e' and 20f' move to the corresponding enabled state by means of movable selector 13.

[0119] The electronic control unit 51' is also configured to move selectors 20a', 20b', 20c', 20d', 20e', and 20f' that are in the enabled state of the first function of the vehicle 1' to a deactivated state when another selector 20b', 20c', 20d', 20e', and 20f' are set to enable a second function of the vehicle 1' that is opposite to, conflicts with, or incompatible with the first function.

[0120] For example, if the selector associated with the driving function of the motor vehicle 1' in the forward direction F is in the enabled state, the electronic control unit 51' is configured to control the actuator 56' associated with the aforementioned selector to automatically move it to the disabled state when another selector associated with the driving function of the motor vehicle in the direction opposite to the forward direction F is moved to the enabled state.

[0121] Conversely, the electronic control unit 51' is also configured to keep selectors 20a', 20b', 20c', 20d', 20e', and 20f' in the enabled state of the first function of enabling the motor vehicle 1' if another selector 20b', 20c', 20d', 20e', and 20f' are set to the enabled state of the second function of enabling the motor vehicle 1' and the second function is compatible with, can coexist with, and / or does not conflict with the first function.

[0122] Alternatively or additionally, if selectors 20a', 20b', 20c', 20d', 20e', 20f' are in an enabled state, the electronic control unit 51' is configured to move the actuator 56' associated with the aforementioned selectors 20a', 20b', 20c', 20d', 20e', 20f' to a deactivated state when the movable selector 13 initially moves away from selectors 20a', 20b', 20c', 20d', 20e', 20f' and subsequently comes into contact with or moves to their vicinity (e.g., in the portions of extensions 14, 15, 17 containing the selectors 20a', 20b', 20c', 20d', 20e').

[0123] In the non-limiting embodiment shown, the connections between the ends 14a, 14b, 15a, 15b, 17a, and 17b and the functions of the motor vehicle 1 are as follows:

[0124] - End 14a is associated with the movement of the motor vehicle 1 in the forward direction F (“drive” function);

[0125] - End 14b is associated with the activation of the parking brake 5 (“parking” function);

[0126] - End 15a is associated with the steering of at least some wheels 4 around the corresponding steering axis according to the angle of the steering wheel 7 around the steering wheel axis ("normal steering" function);

[0127] - End 15b is associated with dynamic traction control (“torque vector control” or “torque steering” function);

[0128] - End 17a is associated with the movement of the motor vehicle in the direction opposite to the forward direction F (“reverse” function);

[0129] - End 17b is associated with the starting of motor vehicle 1 from a stationary state in which motor vehicle 1 is stationary relative to a fixed reference frame (“start control” function).

[0130] The operation of motor vehicle 1' is similar to that of motor vehicle 1, and will be described below only to the extent that the operation of motor vehicle 1' differs from that of motor vehicle 1.

[0131] In use, the user controls multiple functions of the motor vehicle 1' by moving the movable selector 13 relative to the guide 12 and engaging it with selectors 20a', 20b', 20c', 20d', 20e', and 20f'.

[0132] For example, at the end of the parking maneuver, the user moves the movable selector 13 toward end 14b', thereby moving selector 20b' to the enabled state. The electronic control unit 51' detects that selector 20b' is in the enabled state and stores this information.

[0133] If the movable selector 13 engages with selector 20a' and moves to the enabled state to initiate forward movement of the motor vehicle 1', the electronic control unit 51' causes the actuator 56' associated with selector 20b' to move it to the disabled state.

[0134] refer to Figure 7 and Figure 8 The numeral 1'' indicates a motor vehicle according to a third embodiment of the invention. Motor vehicle 1'' is similar to motor vehicle 1 and will be described below only in those aspects that distinguish the former from the latter; where possible, the same reference numerals will be used to indicate motor vehicle 1; similar or equivalent parts of 1''.

[0135] The difference between motor vehicle 1'' and motor vehicle 1 is that it includes a command device 10'' instead of command device 10. Command device 10'' is similar to command device 10 and will be described below only in those aspects that distinguish the former from the latter; where possible, the same reference numerals will be used to indicate the same or equivalent parts of command devices 10 and 10''.

[0136] In particular, the command device 10'' differs from the command device 10 in that it includes a guide 12'' instead of a guide 12.

[0137] Guide 12'' includes another extension 19'' located on the side of extension 14 opposite to extension 15 along the Y direction. Specifically, extension 19'' includes:

[0138] - The portion extending laterally in direction X, 190''; and

[0139] - Extend along direction Y from extension segment 14 to part 191 of part 190''.

[0140] The extension segment 19'' includes an end portion 19b'' associated with the function of the motor vehicle 1 to be controlled or activated. Specifically, the end portion 19b'' is located at and / or is a part of the portion 190''. More specifically, the end portion 19b'' is aligned with the end portion 14b.

[0141] The movable selector 13 can also be positioned at the end 19b'' to select the relevant function.

[0142] In detail, portions 190'' and 191'' are straight and include corresponding openings obtained in the base 11. More specifically, the openings corresponding to portions 190'' and 191'' are adjacent to each other and to the openings of extension segments 14, 15, 16, 17, and 18. Furthermore, in the illustrated embodiment, the openings defining portions 190'' and 191'' have a rectangular shape.

[0143] More specifically, part 191'' is aligned with extension segment 16.

[0144] In the illustrated embodiment, the extension of portion 190'' along direction X is the same as the extension of extension segments 14, 15, and 17. Additionally, preferably, the extension of portion 191'' along direction Y is the same as the extension of extension segments 16 and 18.

[0145] In other words, the extension segment 19'' has an L-shape in a plane orthogonal to the Z direction. Specifically, in the sense of orientation from part 191'' to end 19b'' along the X direction, the distance between point 190'' and extension segment 14 along the Y direction gradually decreases.

[0146] Preferably, end 19b'' is associated with the activation and / or control of the function of the motor vehicle moving in the direction opposite to the forward direction F ("reverse" function);

[0147] The operation of motor vehicle 1'' is similar to that of motor vehicle 1. Therefore, for the sake of brevity, its detailed description is omitted.

[0148] refer to Figure 9 The numeral 1''' indicates a motor vehicle according to a fourth embodiment of the present invention. Motor vehicle 1''' is similar to motor vehicle 1 and will be described below only in those aspects that distinguish the former from the latter; where possible, the same reference numerals will be used to indicate motor vehicle 1; similar or equivalent parts of 1'''.

[0149] The difference between motor vehicle 1''' and motor vehicle 1 is that it includes a command device 10''' instead of command device 10. Command device 10''' is similar to command device 10 and will be described below only in those aspects that distinguish the former from the latter; where possible, the same reference numerals will be used to indicate the same or equivalent parts of command devices 10, 10'''.

[0150] In particular, the command device 10''' differs from the command device 10 in that it includes a knob 31''' instead of a knob 31.

[0151] Knob 31''' is similar to knob 31 and includes:

[0152] - Two elements 34''' and 35''', which are rotatable relative to surface 32''' about rotation axis B;

[0153] - Transducer 52''', which is configured to detect the position of indicator elements 34''' and 35''' relative to the rotation axis B and / or the amount of rotation of elements 34''' and 35''' about the rotation axis B, or generate a signal corresponding to the detected amount.

[0154] In detail, the axis of rotation B is parallel to the Z direction. Furthermore, elements 34''' and 35''' can rotate independently of each other about the axis of rotation B.

[0155] Electronic control unit 51''' is operatively connected to transducer 52''' and configured to control two operating parameters of motor vehicle 1''' based on signals received from transducer 52'''. Specifically, electronic control unit 51''' is configured to extract information from signals generated by transducer 52''' relating to the positions of elements 34''' and 35''' relative to rotation axis B and / or the rotation of elements 34''' and 35''' about rotation axis B, and thus command changes to the operating parameters.

[0156] In detail, the electronic control unit 51''' is configured as follows:

[0157] - Control the first parameter when component 34''' rotates around the axis of rotation B;

[0158] - The second parameter is controlled when component 35''' rotates around the axis of rotation B.

[0159] More specifically, the electronic control unit 51''' is configured to increase the value of a first parameter when the element 34''' rotates about the rotation axis B in a first rotational direction, and to decrease the value of the first parameter when the element 34''' rotates in a second rotational direction opposite to the first rotational direction. Similarly, the electronic control unit 51''' is configured to increase the value of a second parameter when the element 35''' rotates in the first rotational direction, and to decrease the value of the second parameter when the element 35''' rotates in the second rotational direction.

[0160] Preferably, elements 34''' and 35''' have an annular shape with a spherical surface. In other words, elements 34''' and 35''' each include a corresponding annular nut. More specifically, elements 34''' and 35''' are arranged stacked one on top of the other parallel to the axis of rotation B. More specifically, elements 34''' and 35''' are juxtaposed parallel to the axis of rotation B.

[0161] Preferably, the rotation of elements 34''' and 35''' used to control the first parameter and the second parameter respectively can be performed by the user's hand, for example by the thumb and index finger.

[0162] In the illustrated embodiment, elements 34''' and 35''' each further include a corresponding symbol 36''' suitable for indicating the angular position of elements 34''' and 35''' about the axis of rotation B. The symbol 36''' is an alphanumeric character, such as an arrow.

[0163] Similar to the case of knob 31, the parameters controlled by knob 31''' can be selected by the user, i.e., they can be selected from multiple controllable parameters, for example by means of selector 53 and / or by means of movable selector 13''' and / or by means of user interface 6.

[0164] For the reasons stated above, the advantages of the present invention are obvious.

[0165] Because the command device 10; 10'; 10''; 10''' includes a movable selector 13; 13''' that can move along the guide 12; 12'' between multiple positions to enable or select the same number of functions of the motor vehicle 1; 1'; 1''; 1''', many variables of the motor vehicle 1; 1'; 1''' can be controlled in an easy and universal manner. This is particularly suitable for hybrid or electric vehicles.

[0166] Because the guide 12'' is shaped like a grid, the movement of the movable selector 13''' can be performed in a practical and intuitive manner. Specifically, the fact that the guide 12'' includes multiple ends 14a, 14b, 15a, 15b, 17a, 17b; 14a, 14b, 15a, 15b, 17a, 17b, 19b'' and extension segments 16, 18 allows users to select / enable or deselect / disable many functions of the motor vehicle 1'''' in a simple and compact manner.

[0167] Since the command device 10' includes selectors 20a', 20b', 20c', 20d', 20e', and 20f', multiple functions of the motor vehicle 1' can be activated simultaneously. In fact, as long as an incompatible function of the motor vehicle 1' is activated, selectors 20a', 20b', 20c', 20d', 20e', and 20f' remain in their respective activated states.

[0168] Since the command device 10; 10'; 10'' includes a tactile sensor 52 configured to detect the user's touch, one or more parameters of the motor vehicle 1; 1' can be changed by touching the knob 31 in a convenient and simple manner.

[0169] Since the command device 10''' includes elements 34''' and 35''', one or more parameters of the motor vehicle 1''' can be changed by conveniently rotating the elements 34''' and 35''' about the axis of rotation B in a convenient and simple manner.

[0170] Finally, the command device 10; 10'; 1''; 1''' and the motor vehicle 1; 1'; 1'''; 1''' according to the invention can be modified and varied, but such modifications and variations do not exceed the scope of protection set forth in the appended claims.

[0171] The functions of the motor vehicle 1;1';1'';1''' that can be controlled by a user by moving the movable selector 13;13''' relative to the guide 12;12'' may differ from those listed above. For example, the functions may include changing at least one control variable of the wheel 4 and / or changing at least one control variable of the suspension of the motor vehicle 1;1';1'';1'''. The same applies to parameters that can be controlled by means of the knob 13;13'''.

[0172] The shape of the guide 12 may differ from the shape shown. Specifically, the guide 12 may have multiple extension segments 14, 15, 17 (not three) and / or multiple ends 14a, 14b, 15a, 15b, 17a, 17b (not six). For example, the guide 12 may have fewer than or more than six ends 14a, 14b, 15a, 15b, 17a, 17b. Furthermore, the extension segments 14, 15, 17 may be at least partially curved and not straight.

[0173] The shape of the guide 12'' may differ from the shape shown. Specifically, the guide 12'' may have multiple extension segments 14, 15, 17, 19'' (not four) and / or multiple ends 14a, 14b, 15a, 15b, 17a, 17b, 19b'' (not seven). For example, the guide 12'' may have fewer than or more than seven ends 14a, 14b, 15a, 15b, 17a, 17b. Furthermore, the extension segments 14, 15, 17, 19b'' may be at least partially curved and not straight.

[0174] The tactile sensor 52 can be a surface acoustic wave type or an optical imaging type resistive sensor.

[0175] The electronic control unit 51; 51''' can be configured to control a single or more than two operating parameters of the motor vehicle 1; 1'; 1''; 1''' based on signals received from the tactile sensor 52 or the transducer 52'''.

[0176] Command device 10''; 10''' may include selectors 20a', 20b', 20c', 20d', 20e', 20f'.

[0177] Command device 10; 10'; 10''' may include guide 12''.

[0178] The knob 31''' may include only one of elements 34''' and 35''' instead of both. Alternatively, the knob 31''' may include more than two elements 34''' and 35''', each of which is rotatable relative to the surface 32''' about the axis of rotation B and is associated with a corresponding different parameter of the motor vehicle 1'''.

[0179] The knob 31''' may also include area 33 and tactile sensor 52.

[0180] Selectors 20a', 20b', 20c', 20d', 20e', and 20f' may include corresponding capacitive buttons. Specifically, selectors 20a', 20b', 20c', 20d', 20e', and 20f' may include corresponding lighting devices configured to illuminate when the relevant selector is enabled and turn off when the selector is disabled, or to emit light of a first color (e.g., green) when the selector is enabled and emit light of a second color (e.g., red) when the selector is disabled.

[0181] Alternatively, selectors 20a', 20b', 20c, 20d', 20e', and 20f' include corresponding mechanical buttons configured to each present a first position associated with an enabled state and a second position associated with a disabled state.

[0182] The command device 10' includes selectors 20a', 20b', 20c', 20d', 20e', and 20f' located only at some of the extension segments 14, 15, and 17.

[0183] In addition, the electronic control units 51, 51', and 51''' can be different from or overlap with each other.
