Description

TECHNICAL FIELD The present disclosure relates to a mounting arrangement for an electric drive unit (EDU) assembly, a vehicle including the mounting arrangement and to a method of mounting an EDU assembly to a vehicle. BACKGROUND Driven by environmental, economic and technological factors, vehicles, for example automotive vehicles, are transitioning from diesel and petrol internal combustion engines (ICEs) towards more sustainable alternatives, such as battery electric vehicles (BEV) or hybrid electric vehicles (HEV). Such vehicles include an electric drive unit (EDU) assembly for providing tractive power to the wheels of the vehicle. The EDU assembly is mounted to the vehicle body structure, or vehicle chassis. In use, the components of the EDU assembly generate considerable levels of vibration and noise which may be transferred to the vehicle body structure. Such noise and vibration is uncomfortable for the user, and may lead to loosening of mounts of the vehicle body structure. The loosening of the mounts may exacerbate the levels of vibration, and could even result in the EDU assembly becoming disconnected from the vehicle body structure. It is an aim of the present invention to provide a solution to this issue. SUMMARY OF THE INVENTION Aspects and embodiments of the invention provide a mounting arrangement, a vehicle and a method of mounting an electric drive unit (EDU) assembly to a vehicle body structure of a vehicle as claimed in the appended claims. According to an aspect of the present teachings there is provided a mounting arrangement for mounting an electric drive unit (EDU) assembly to a vehicle body structure, the mounting arrangement comprising: a first EDU mounting bracket configured to be located on a first side of the EDU assembly; wherein the first EDU mounting bracket comprises a first flexible mount arrangement configured to mount the EDU assembly to the first EDU mounting bracket, and a second flexible mount arrangement configured to mount the first EDU mounting bracket to the vehicle body structure so as to maintain the EDU assembly in a desired position and orientation relative to the vehicle body structure. Optionally, the second flexible mount arrangement comprises a mass carrying mount and a torque reacting mount spaced apart from the mass carrying mount. Advantageously, the first flexible mount arrangement acts as a mass carrier and support the mass of the EDU assembly. The second flexible mount arrangement performs the dual function of acting as a mass carrier and a torque resistor. The EDU mounting bracket therefore performs the function of holding the mass of the EDU assembly in the desired position and orientation and reducing the likelihood of the EDU assembly moving relative to the vehicle body structure due to applied torques and loads to the EDU assembly. The spacing of the mass carrying mount and torque reacting mount provides space for the first flexible mount arrangement, thereby improving space efficiency of the mounting arrangement. Additionally, the first and second flexible mount arrangements provide dual vibration isolation of the EDU assembly as the first flexible mount arrangement absorbs a portion of the vibration as opposed to transferring all of the vibration to the second flexible mount arrangement. This increases the overall stiffness of the mounting arrangement and enables damping of different frequencies at the first and second isolation stages, thereby improving the noise, vibration and harshness (NVH) performance of the vehicle body structure, in use. Optionally, the first flexible mount arrangement is configured to mount the EDU assembly to the first EDU mounting bracket in a lateral direction with respect to a fore-aft axis of the vehicle body structure. According to an aspect of the present teachings there is provided a mounting arrangement for mounting an electric drive unit (EDU) assembly to a vehicle body structure, the mounting arrangement comprising: a first EDU mounting bracket configured to be located on a first side of an EDU assembly and a second EDU mounting bracket configured to be located on a second side of the EDU assembly; wherein each of the first and second EDU mounting brackets comprise a first flexible mount arrangement configured to mount the EDU assembly to the respective first or second EDU mounting bracket, and a second flexible mount arrangement configured to mount the respective first or second mounting bracket to the vehicle body structure so as to maintain the EDU assembly in a desired position and orientation relative to the vehicle body structure.

Optionally, the first and / or second flexible mount arrangement is configured to mount the second mounting bracket to the vehicle body structure so as to maintain the EDU assembly in a desired position and orientation relative to the vehicle body structure. Advantageously, the second EDU mounting bracket provides mass carrying and support of the mass of the EDU assembly, as well as torque resistance, on a second side of the EDU assembly. Thus helps to further improve supporting of the mass of the EDU assembly in the desired position and orientation and reducing the likelihood of the EDU assembly moving relative to the vehicle body structure due to applied torques and loads to the EDU assembly.

Optionally, the first EDU mounting bracket comprises a first face configured to face towards the EDU assembly, and an opposing second face configured to face away from the EDU assembly. Optionally, the first flexible mount arrangement is located on the first face of the first EDU mounting bracket. Optionally, the second flexible mount arrangement is located on the second face of the first EDU mounting bracket. Advantageously, providing the first flexible mount arrangement on the face facing the EDU assembly helps to facilitate direct mounting between the first face and the EDU assembly. Providing the second flexible mount arrangement on the face facing away from the EDU assembly helps to facilitate direct mounting between the second face of the EDU assembly and the vehicle body structure. Providing the first and second flexible mount arrangements on opposing faces helps to prevent each flexible mount arrangement from obstructing the other flexible mount arrangement. Overall, the arrangement improves packing and compactness of the EDU assembly to the vehicle body structure. Optionally, the first flexible mount arrangement of the first EDU mounting bracket defines a mounting axis. Optionally, the mounting axis of the first flexible mount arrangement is configured to extend parallel to a longitudinal axis of the EDU assembly. Advantageously, the mounting axis of the first flexible mount arrangement extending parallel to the longitudinal axis of the EDU assembly helps to facilitate carrying of the mass of the EDU assembly by the first EDU mounting bracket, so that the mass of the EDU assembly can be transferred to the second flexible mount arrangement (and therefore to the vehicle body structure). According to another aspect of the invention, there is provided a subassembly for mounting to a vehicle body structure of a vehicle, comprising: an electric drive unit (EDU) assembly; and a mounting arrangement comprising: a first EDU mounting bracket located on a first side of the EDU assembly; wherein the first EDU mounting bracket comprises a first flexible mount arrangement configured to mount the EDU assembly to the first EDU mounting bracket, and a second flexible mount arrangement configured to mount the first EDU mounting bracket to the vehicle body structure so as to maintain the EDU assembly in a desired position and orientation relative to the vehicle body structure; and wherein the second flexible mount arrangement comprises a mass carrying mount and a torque reacting mount spaced apart from the mass carrying mount. Advantageously, the first flexible mount arrangement acts as a mass earner and support the mass of the EDU assembly. The second flexible mount arrangement performs the dual function of acting as a mass carrier and a torque resistor. The EDU mounting bracket therefore performs the function of holding the mass of the EDU assembly in the desired position and orientation and reducing the likelihood of the EDU assembly moving relative to the vehicle body structure due to applied torques and loads to the EDU assembly. The spacing of the mass carrying mount and torque reacting mount provides space for the first flexible mount arrangement, thereby improving space efficiency of the mounting arrangement. Additionally, the first and second flexible mount arrangements provide dual vibration isolation of the EDU assembly as the first flexible mount arrangement absorbs a portion of the vibration as opposed to transferring all of the vibration to the second flexible mount arrangement. This increases the overall stiffness of the mounting arrangement and enables damping of different frequencies at the first and second isolation stages, thereby improving the noise, vibration and harshness (NVH) performance of the vehicle body structure, in use. According to another aspect of the invention, there is provided a vehicle comprising: a vehicle body structure; an electric drive unit (EDU) assembly; and a mounting arrangement according to a previous aspect for mounting the EDU assembly to the vehicle body structure, wherein the first flexible mount arrangement mounts the EDU assembly to the first EDU mounting bracket in a lateral direction with respect to a fore-aft axis of the vehicle body structure. Advantageously, the first flexible mount arrangement acts as a mass carrier and support the mass of the EDU assembly, and the second flexible mount arrangement performs the dual function of acting as a mass carrier and a torque resistor. The EDU mounting bracket therefore performs the function of holding the mass of the EDU assembly in the correct position and reducing the likelihood of the EDU assembly moving relative to the vehicle body structure due to applied torques and loads to the EDU assembly. Additionally, the first and second flexible mount arrangements provide dual vibration isolation of the EDU assembly as the first flexible mount arrangement absorbs a portion of the vibration as opposed to transferring all of the vibration to the second flexible mount arrangement. This increases the overall stiffness of the mounting arrangement and enables damping of different frequencies at the first and second isolation stages, thereby improving the noise, vibration and harshness (NVH) performance of the vehicle body structure, in use. Optionally, the EDU assembly comprises at least one snubbing face located on an outer surface of a casing of the EDU assembly or on the first EDU mounting bracket. Optionally, the at least one snubbing face is at least partially aligned with the first or second flexible mount arrangement in the lateral direction with respect to the fore-aft axis of the vehicle body structure. Advantageously, the snubbing face helps to provide protection to the first or second flexible mount arrangement in the event of an impact to the vehicle, which may cause the flexible mount to move laterally towards or away from the EDU assembly. In the event of such an impact, the snubbing face contacts the first or second flexible mount arrangement and exerts a force in an opposing direction to the movement of the first or second flexible mount arrangement towards the snubbing face. This helps to prevent significant moment / deformation of the flexible mount arrangement, therefore helping to prevent permanent deformation 6 of the first or second flexible mount arrangement and reducing the likelihood of failure of the first or second flexible mount arrangement. Optionally, the mounting arrangement comprises the second EDU mounting bracket. Optionally, the first and second EDU mounting brackets are located on opposing sides of the EDU assembly. Advantageously, the second EDU mounting bracket provides mass carrying and support of the mass of the EDU assembly, as well as torque resistance, on a second side of the EDU assembly. Thus helps to further improve supporting of the mass of the EDU assembly in the desired position and orientation and reducing the likelihood of the EDU assembly moving relative to the vehicle body structure due to applied torques and loads to the EDU assembly. Optionally, the plate of the mass carrying mount extends parallel to a longitudinal axis of the EDU assembly. According to another aspect of the invention, there is provided a method of mounting an EDU assembly to a vehicle body structure of a vehicle, the method comprising the steps of: providing a mounting arrangement according to a previous aspect comprising a first EDU mounting bracket; mounting the first EDU mounting bracket to the EDU assembly via the first flexible mount arrangement; mounting the first EDU assembly to the vehicle body structure of the vehicle via the second flexible mount arrangement. Advantageously, the first flexible mount arrangement acts as a mass carrier and support the mass of the EDU assembly. The second flexible mount arrangement performs the dual function of acting as a mass carrier and a torque resistor. The EDU mounting bracket therefore performs the function of holding the mass of the EDU assembly in the desired position and orientation and reducing the likelihood of the EDU assembly moving relative to the vehicle body structure due to applied torques and loads to the EDU assembly. The spacing of the mass carrying mount and torque reacting mount provides space for the first flexible mount arrangement, thereby improving space efficiency of the mounting arrangement. Additionally, the first and second flexible mount arrangements provide dual vibration isolation of the EDU assembly as the first flexible mount arrangement absorbs a portion of the vibration as opposed to transferring all of the vibration to the second flexible mount arrangement. This increases the overall stiffness of the mounting arrangement and enables damping of different frequencies at the first and second isolation stages, thereby improving the noise, vibration and harshness (NVH) performance of the vehicle body structure, in use.

DETAILED DESCRIPTION Figures 1 and 2 show an example of an electric vehicle (EV) 10. The electric vehicle 10 includes a vehicle body structure 11 and a battery or battery pack 40. The battery 40 is mounted to and supported by the vehicle body structure 11, in use. The battery 40 may be recharged from an external electrical source. The electric vehicle 10 comprises a pair of front wheels 12 at a front axle 28 and a pair of rear wheels 14 at a rear axle 38. The vehicle has at least one electric drive unit (EDU) assembly 20, 30 by which one or more of the wheels 12, 14 are driven. In the illustrated embodiment, the vehicle 10 comprises two electric drive unit assemblies 20, 30, each associated with one of the pairs of wheels 12, 14. In other embodiments, the vehicle 10 may have a dedicated EDU for each of the front wheels 12 and / or a dedicated EDU for each of the rear wheels 14. In the illustrated embodiment, the front wheels 12 are driven by a first electric drive unit (EDU) assembly 20. The first EDU assembly 20 includes a first motor 22, a front transmission 24 and power electronics 26. The rear wheels 14 are driven by a second electrical drive unit (EDU) assembly 30. The second EDU assembly 30 includes a second motor 32, a rear transmission 34 and power electronics 36. The first EDU assembly 20 and the second EDU assembly 30 each receive a DC supply from battery 40. The first EDU assembly 20 can be called a first propulsion unit and the second EDU assembly 30 can be called a second propulsion unit. As used herein, the term “transmission” may refer to a device with a plurality of gears through which torque can be transmitted from the drive unit to one or more of the wheels. For example, this may refer to a differential, transaxle, and / or a gearbox. In other embodiments, the electric vehicle 10 may include only one EDU assembly 20, 30. For example, the second EDU 30 may be omitted in embodiments where the electric vehicle 10 is a “front-wheel drive” vehicle, or the first EDU assembly 20 may be omitted in embodiments where the electric vehicle is a “rear-wheel drive” vehicle. In further embodiments, one or more of the wheels 12, 14 may be driven individually by a dedicated EDU. For example, the front wheels 12 may each be connected to one of a pair of front EDUs. Referring now to Figures 3 to 6, the first EDU assembly 20 is illustrated, referred to hereafter as an EDU assembly 20. It shall be appreciated that although the teachings are described in relation to the first EDU assembly 20, the teachings are also applicable to the second EDU assembly 30, or to any alternative arrangements of first and / or second EDU assembly 20, 30, for example those described above. The vehicle 10 defines a central longitudinal axis or fore-aft axis a-a, a left side 10a and a right side 10b with respect to the central longitudinal axis a-a, a front 10c and a rear 10d with respect to a principal direction of travel of the vehicle 10. It shall be understood that the principal direction of travel corresponds to when the 8 vehicle 10 is driving substantially forwards under normal operating conditions. It shall be appreciated that the central longitudinal axis a-a of the vehicle 10 is the same as a central longitudinal axis of the vehicle body structure 11. Accordingly, the longitudinal axis a-a can be used interchangeably to refer to the vehicle 10 or the vehicle body structure 11. A front portion of the vehicle body structure 11 is illustrated in Figure 3. The vehicle body structure 11, known as a vehicle chassis or frame, supports and holds together components of the vehicle 10, for example the battery arrangement 40 and the front and / or rear EDU assembly 20, 30, and provides structural integrity, strength and safety to the vehicle 10 in the event of a frontal impact arising from a collision. The portion of the vehicle body structure 11 illustrated in Figure 3 is located towards the front 10c of the vehicle 10 (i.e. closer to the front side 10c than the rear side 10d), however it shall be appreciated that in alternative embodiment the portion of the vehicle body structure 11 may be located towards the rear 10d of the vehicle 10, and may be a rear potion of the vehicle body structure 11. The vehicle 10 includes a mounting arrangement 50 configured to mount the EDU assembly 20 to the vehicle body structure 11, for example towards the front side 10c of the vehicle 10. The mounting arrangement 50 may be mounted to a support arrangement 17 forming part of the vehicle body structure 11 and arranged above the EDU assembly 20. The support arrangement 17 may be a frame or a tray. The EDU assembly 20 may be suspended from the support arrangement 17, as will be described in more detail below. In addition, the mounting arrangement 50 is configured to mount the EDU assembly 20 to first and second sides 11a, 11b of the vehicle body structure 11, as illustrated in Figure 4. As such, the mounting arrangement 50 is configured to mount the EDU assembly to more than one located on the vehicle body structure 11. As illustrated in Figure 3, the EDU assembly 20 is mounted laterally with respect to the vehicle body structure 11. Put another way, a longitudinal axis b-b of the EDU assembly 20 is orientated substantially perpendicularly to a longitudinal axis a-a of the vehicle body structure 11. As such, the EDU assembly 20 extends partially between the first and second sides 11a, 11b of the vehicle body structure 11. The term “longitudinal” in reference to a direction is taken to mean a direction parallel to the longitudinal axis a-a of the vehicle 10. The term “lateral” in reference to a direction is taken to mean a direction perpendicular to the longitudinal axis a-a of the vehicle 10, i.e. extending between the left and right sides 10a, 10b of the vehicle 10. However, as the EDU assembly 20 is mounted laterally, the longitudinal axis b-b of the EDU assembly 20 is parallel to the lateral direction. The EDU assembly 20 includes an EDU housing 19 for housing internal components of the EDU assembly 20, for example the transmission 24 and motor 22, and one or more mounting faces 21 configured to mount the mounting arrangement 50 to the EDU assembly 20. The mounting faces 21, some of which are illustrated in Figure 6, are configured to engage with corresponding formations of the mounting arrangement 50, as will be described in more detail below. The one or more mounting faces 21 may be located on an EDU housing 19 of the EDU assembly 20. The mounting arrangement 50 includes a first EDU mounting bracket 52a and a second EDU mounting bracket 52b. The first EDU mounting bracket 52a is located on a first face 20a of the EDU assembly 20 and the second EDU mounting bracket 52b is located on a second face 20b of the EDU assembly 20. In the embodiment shown in Figure 5, the first face 20a of the EDU assembly 20 is a “drive side”, i.e. where components (for example gears) of the transmission 34 are housed, and the second side is a “non-drive” side, i.e. where one or more of the main bearings of the EDU assembly 20 may be located. As illustrated in Figures 5 and 6, the second or “non-drive” face 20b includes a cover 23 mounted thereto for forming a cover over at least one of the main bearings of the EDU assembly 20. The cover 23 is mounted to the EDU assembly 20, in particular to the EDU housing 19, by a plurality of fasteners. In the embodiment of Figure 5, the fasteners are a plurality of nut and bolts, however any suitable fastening arrangement may be used. The cover 23 may be formed form aluminium. This has the advantage of reducing electromagnetic emission from the EDU assembly 20. The cover 23 may include a reinforcement arrangement, for example a plurality of webs or ribs, extending thereover. It shall be appreciated that in some embodiments, the cover 23 may be omitted and the mounting arrangement 50 may be located directly on the second face 20b of the EDU housing 19. The term “second face 20b” therefore covers embodiments wherein the second EDU mounting bracket 52b is mounted to the cover 23 (i.e. the cover 23 defines the second face 20b) and embodiments where the second EDU mounting bracket 52b is mounted directly to the EDU housing 19. The first and second faces 20a, 20b of the EDU assembly 20 are opposing sides. As such, the first and second mounting brackets 52a, 52b are located on opposing sides of the EDU assembly 20. Put another way, the EDU assembly 20 is located between the first and second EDU mounting brackets 52a, 52b. It shall be appreciated that in alternative embodiments, only one of the first and second EDU mounting bracket 52a, 52b may be used to mount the EDU assembly 20 to the vehicle body structure 11. Alternatively, more than two EDU mount brackets 52a, 52b may be used to mount the EDU assembly 20 to the vehicle body structure 11. As such, there may be an EDU mounting bracket 52a, 52b located on only one of the first or second face 20a, 20b of the EDU assembly 20. The first EDU mounting bracket 52a includes a first face 54a and an opposing second face 54b. The first face faces towards the EDU assembly 20, in use, and the second face 54b faces away from the EDU assembly 20 (for example towards the respective first or second face 20a, 20b of the EDU assembly 20), in use. Put another way, the first face 54a faces in an opposing direction to the second face 54b. The first faces 54a of the first and second EDU mounting brackets 52a, 52b face towards each other, and the second faces 54b of the first and second EDU mounting brackets 52a, 52b face in opposing directions. The first and second faces 54a, 54b are substantially planar. The first and second EDU mounting brackets 52a, 52b may be separate EDU mounting brackets 52a, 52b, as illustrated in Figures 4 and 5. Alternatively, the first and second EDU mounting brackets 52a, 52b may be connected by a frame arrangement or frame members extending therebetween to connect the first and second EDU mounting brackets 52a, 52b. The first EDU mounting bracket 52a is of a dissimilar shape to the second EDU mounting bracket 52b, as will be described in more detail below. The dissimilar shape of the first EDU mounting bracket 52a relative to the second EDU mounting bracket 52b helps to avoid obstruction of components of the EDU assembly 20, for example bearings and / or gears located within the EDU housing 19, thereby improving packaging and compactness of the EDU assembly 20 and mounting arrangement 50. The first EDU mounting bracket 52a is of a substantially triangular configuration, as illustrated in Figure 5. Substantially is taken to mean that the shape of the first EDU mounting bracket 52a may vary from triangular. For example, in the embodiment illustrated in Figure 5, sides of the substantially triangular first EDU mounting bracket 52a are non-linear. It shall be appreciated that the shape of the second EDU mounting bracket 52b may be substantially triangular, for example may vary from triangular. The sides of the substantially triangular second EDU mounting bracket 52b may be non-linear. The first and second EDU mounting brackets 52a, 52b each include a reinforcement arrangement 51 configured to provide reinforcement to the respective first or second EDU mounting bracket 52a, 52b. The reinforcement arrangement 51 includes on or more reinforcing ribs and / or reinforcing webs, illustrated in Figure 5 in relation to the first EDU mounting bracket 52a. The reinforcement arrangement 51 may extend over a majority of the first and / or second faces 54a, 54b. For example, the reinforcement arrangement 51 may extend over an entirety of the first and / or second faces 54a, 54b. The reinforcing ribs / webs are substantially linear and non-parallel in the embodiment illustrated in Figure 5, however any suitable arrangement of ribs / webs in any suitable orientation may be used to reinforce the first and / or second EDU mounting bracket 52a, 52b. The first and second EDU mounting brackets 52a, 52b each comprise a first flexible mount arrangement 58a-f configured to mount the EDU assembly 20 to the respective first or second EDU mounting bracket 52a, 52b. The first and second EDU mounting brackets 52a, 52b are mounted in a lateral direction with respect to the fore-aft (or longitudinal) axis a-a of the vehicle body structure 11 so as to mount the EDU assembly 20 laterally with respect to the vehicle 10. The first and second EDU mounting brackets 52a, 52b each comprise a second flexible mount arrangement 60a-d configured to mount the respective first or second EDU mounting bracket 52a, 52b to the vehicle body structure 11 so as to maintain the EDU assembly 20 in a desired position and orientation relative to the vehicle body structure 11. The first flexible mount arrangement 58a-f is located on the first face 54a of the first and second EDU mounting brackets 52a, 52b. The second flexible mount arrangement 60a-d is located on the second face 54b of the first and second EDU mounting brackets 52a, 52b. Providing the first flexible mount arrangement 58a-f on the second face 54b facing the EDU assembly 20 helps to facilitate direct mounting between the respective first or second face 20a, 20b of the EDU assembly 20 and the second face 54b of the respective first or second EDU mounting bracket 52a, 52b. Providing the second flexible mount arrangement 60a-d on the second face 54b facing away from the EDU assembly 20 helps to facilitate direct mounting between the second face 54b of the EDU assembly 20 and the vehicle body structure 11. The first flexible mount arrangement 58a-f acts as a mass carrier and supports the mass of the EDU assembly 20, and the second flexible mount arrangement 60a-d performs the dual function of acting as a mass carrier and a torque resistor, as will be described in more detail below. Each of the EDU mounting brackets 52a, 52b therefore perform the function of holding the mass of the EDU assembly 20 in the desired position and orientation and reducing the likelihood of the EDU assembly 20 moving relative to the vehicle body structure 11 due to applied torques and loads of the EDU assembly 20. Additionally, the first and second flexible mount arrangement 58a-f, 60a-d provide dual vibration isolation of the EDU assembly 20. This is because the first flexible mount arrangement 58a-f absorbs a portion of the vibration, as opposed to transferring all of the vibration to the second flexible mount arrangement 60a-d. This enables damping of different frequencies at the first and second isolation stages (i.e. the first flexible mount arrangement 58a-f and the second flexible mount arrangement 60a-d), thereby improving the noise, vibration and harshness (NVH) performance of the vehicle 10, in use. Although the teachings relating to the first and second flexible mount arrangements 58a-f, 60a-d are applicable to both the first and second EDU mounting brackets 52a, 52b, the first and second flexible mount arrangements 58a-c, 60a, 60b of the first EDU mounting bracket 52a will be described hereafter for reasons of clarity and brevity. Furthermore, some of the feature of the second EDU mounting bracket 52b are not labelled in Figure 5 for reasons of clarity, however it shall be appreciated that the teachings are applicable to both the first and second EDU mounting brackets 52a, 52b. The first EDU mounting bracket 52a defines an upper region 56a and a lower region 56b, in use. The terms “upper” and “lower” are taken to mean upper and lower when the vehicle 10 is assembled and in normal use (i.e. supported on a ground surface). The upper region 56a is taken to mean a region which is spaced apart from a lowermost edge of the first EDU mounting bracket 52a, in use. As such, the upper region 56a may include more than half of the first EDU mounting bracket 52a. The first flexible mount arrangement 58a-c is located on the upper region 56a of the first EDU mounting bracket 52a. Providing the first flexible mount arrangement 58a-c on the upper region 56a helps to improve weight distribution of the EDU assembly 20 when supported by the vehicle body structure 11. Additionally, the location of the first flexible mount arrangement 58a-c on the upper region 56a helps to avoid obstruction of components of the EDU assembly, for example bearings and / or gears. The upper region 56a defines a greater surface area than the lower region 56b. This provides space and structural support for the first flexible mount arrangement 58a-c. The first flexible mount arrangement 58a-c includes one or more first flexible mounts 58a-c. In the embodiment illustrated in Figure 5, the first flexible mount arrangement 58a-c includes three first flexible mounts 58a-c. The first EDU mounting bracket 52a includes a plurality of mounting bores 59a-c each configured to receive a respective first flexible mount 58a-c. The number of mounting bores 59a-c may correspond to the number of first flexible mounts 52a-c. As such, in the embodiment of the Figures, three mounting bores 59a-c are provided. Each of the plurality of first flexible mounts 58a-c is spaced apart from the other of the plurality of first flexible mounts 58a-c so as to improve mass distribution of the EDU assembly 20 supported by the first EDU mounting bracket 52a. The three first flexible mounts 58a-c are arranged in a substantially triangular configuration, wherein each of the flexible mounts is a vertex of the triangle. In the embodiment shown in Figure 5, one of the first flexible mounts 58a is an uppermost first flexible mount 58a, one of the first flexible mounts 58c is a lowermost first flexible mount 58c, and one of the first flexible mounts 58b is located intermediate the uppermost and lowermost flexible mounts 58a, 58c, Furthermore, the three first flexible mounts 58a-c are misaligned in a substantially vertical direction extending transversely to the longitudinal axis b-b of the EDU assembly 20, in use. Each of the first flexible mounts 58a-c lies on substantially the same plane vertical plane, i.e. a plane extending transverse to the longitudinal axis a-a of the vehicle body structure 11. Put another way, each of the first flexible mounts 58a-c located on the first EDU mounting bracket 52a is spaced apart substantially the same distance from the longitudinal axis a-a of the vehicle 10 as the other of the first flexible mounts 58a-c. It shall be appreciated that the arrangement of the first flexible mounts 58a-c is one of many possible embodiments, and any suitable number of first flexible mounts 58a-c provided in any suitable arrangement may be used to mount the first EDU mounting bracket 52a to the EDU assembly 20. The first flexible mount arrangement 58a-c extends parallel to the lateral direction, i.e. in a direction parallel to the longitudinal axis b-b of the EDU assembly 20. In particular, each of the one or more flexible mounts 58a-c defines a mounting axis, and each of the mounting axes of the one or more flexible mounts 58a-c extends parallel to the lateral direction, i.e. in a direction parallel to the longitudinal axis b-b of the EDU assembly 20. As such, the first flexible mount arrangement 58a-c is orientated substantially transversely to the longitudinal axis a-a of the vehicle 10. It shall be appreciated that a mounting axis of each of the one or more first flexible mounts 58d-f of the second EDU mounting bracket 52b extends parallel to the lateral direction, i.e. in a direction parallel to the longitudinal axis b-b of the EDU assembly 20. As such, the mounting axes of the first flexible mounts 58a-c on the first EDU mounting bracket 52a are parallel to each other and to the mounting axes of the first flexible mounts 58d-f on the second EDU mounting bracket 52b. The first flexible mount arrangement 58a-c located on the first EDU mounting bracket 52a is configured to be longitudinally offset from the first flexible mounting arrangement 58d-f located on the second EDU mounting bracket 52b with respect to the longitudinal axis b-b of the EDU assembly 20. In particular, each of the first flexible mounts 58a-c located on the first EDU mounting bracket 52a is configured to be misaligned with each of the one or more first flexible mounts 58d-f located on the second EDU mounting bracket 52b. The longitudinal offset of the first flexible mount arrangement 58a-c of the first EDU mounting bracket 52a relative to the first flexible mount arrangement 58d-f of the second EDU mounting bracket 52b helps to avoid obstruction of components of the EDU assembly 20, for example bearings and / or gears of the transmission 24, thereby improving packaging and compactness of the EDU assembly 20 and mounting arrangement 50. One of the first flexible mounts 58a of the first flexible mount arrangement 58a-f is illustrated in detail in Figure 7. It shall be appreciated that each of the first flexible mounts 58a-f of the first flexible mount arrangement 58a-f are of substantially the same configuration. Accordingly, for reasons of conciseness and brevity, only the first flexible mount 58a is described in detail. In alternative embodiments, the first flexible mounts 58a-f may be of different embodiments. For example, flexible mounts located at regions of the EDU assembly 20 of greater mass may have a greater diameter. The first flexible mount 58a includes an annular body 70 at least partially surrounding a resilient element 72. The annular body 70 may be formed from a metallic material, for example a metal alloy. A diameter of the annular body 70 may be in the range 10mm to 250mm, for example in the range 30mm to 150mm. The resilient element 72 may be an elastomeric body, for example a rubber body or block. The resilient element 72 may be provided as a unitary body, or a series of resilient bodies may be provided to form the resilient element 72. In particular, the resilient element 72 may be manufactured from a hard rubber. Alternatively, the resilient element 72 may be a spring arrangement. The resilient element 72 may be annular. The annular body 70 and resilient element 72 provide secure mounting between the EDU assembly 20, the first flexible mount 58a and the first EDU mounting bracket 52a, whilst improving damping and NVH of the vehicle body structure 11, in use. The first flexible mount 58a also includes an inner sleeve 74. The inner sleeve 74 may be formed from a metallic material, for example a metal alloy. The inner sleeve 74 is located within the annular body 70 and is configured to receive a fastener 76 therethrough. The resilient element 72 is located between the annular body 70 and the inner sleeve 74, as illustrated in Figure 7. The resilient element 72 may extend radially around the inner sleeve 74. The fastener 76 provides secure mounting of the first flexible mount 58a to the first EDU mounting bracket 52a and the EDU assembly 20, and the inner sleeve 74 helps to provide support for the fastener 76 and the resilient element 72. Additionally, the inner sleeve 74 increases stiffness at a centre of the first flexible mount 58a. In use, the fastener 76 extends through the mounting bore 59a of the first EDU mounting bracket 52a, through the inner sleeve 74 and into the corresponding mounting face 21 of the EDU assembly 20 to mount the first EDU mounting bracket 52a to the EDU assembly 20. The fastener 76 also extends through the annular body 70 and the resilient element 72. In the embodiment of Figure 7, the fastener 76 is a nut and bolt, however it shall be appreciated that any suitable fastener may be used. As illustrated in Figures 6 and 7 and described above, the EDU assembly 20 includes a plurality of mounting faces 21 located thereon. The mounting faces 21 are located on both the first face 20a and the second face 20b of the EDU assembly 20. The second face 20b is illustrated in Figure 6. The number of mounting faces 21 corresponds to the number of first flexible mounts 58a-f. As such, three mounting faces 21 are located on the first face 20a of the EDU assembly 20, and three mounting faces 21 are located on the second face 20b of the EDU assembly 20. Each mounting face 21 is configured to engage with one of the flexible mounts 58a-f. The mounting faces 21 on the second face 20b of the EDU assembly 20 are located on the cover 23 in the embodiment illustrated in Figure 6. In alternative embodiments, the mounting faces 21 may be located on the EDU housing 19 on the second face 20b of the EDU assembly 20. The second flexible mount arrangement 60a-d includes a mass carrying mount 60a, 60c and a torque reacting mount 60b, 60d spaced apart from the respective mass carrying mount 60a, 60c. The second flexible mount arrangement 60a-d therefore provides the dual function of acting as a mass carrier and a torque resistor. This helps to hold the mass of the EDU assembly 20 in the desired position and orientation, whilst reducing the likelihood of the EDU assembly 20 moving relative to the vehicle body structure 11 due to applied torques and loads of the EDU assembly 20. It shall be appreciated that the mass carrying mount 60a and the torque reacting mount 60b are located on the first EDU mounting bracket 52a, and the mass carrying mount 60b and the torque reacting mount 60d are located on the second EDU mounting bracket 52b. In the embodiment of the Figures, the second flexible mount arrangement 60a-d therefore includes two mass carrying mounts 60a, 60c and two torque reacting mounts 60b, 60d. It shall be appreciated that in alternative embodiments, any suitable number of mass carrying mounts 60a, 60c and / or torque reacting mounts 60b, 60d may be provided. The mass carrying mounts 60a, 60b are of substantially the same configuration, and the torque reacting mounts 60b, 60d are of substantially the same configuration. The mass carrying mounts 60a, 60c are arranged in substantially the same orientation. The torque reacting mounts 60b, 60d may be orientated substantially symmetrically about the central longitudinal axis a-a of the vehicle 10, or may be offset about the central longitudinal axis a-a, for example depending on packaging constraints. Accordingly, for reasons of conciseness and brevity, only the mass carrying mount 60a and torque reacting mount 60b of the first EDU mounting bracket 52a will be described in detail. The first flexible mount arrangement 58a-c of the first EDU mounting bracket 52a is located between the mass carrying mount 60a and the torque reacting mount 60b. In the embodiment of the Figures, an entirety of the first flexible mount arrangement 58a-c is located between the mass carrying mount 60a and the torque reacting mount 60b. This helps to improve space efficiency of the mounting arrangement 50. The mass carrying mount 60a is located on the upper region 56a, and the torque reacting mount 60b is located on the lower region 56b. In particular, the mass carrying mount 60a is located at an uppermost edge of the upper region 56a, and the torque reacting mount 60b is located at a lowermost edge of the lower region 56b. The location of the mass carrying mount 60a in the upper region 56a, for example at the uppermost edge, helps to facilitate mounting of the EDU assembly 20 to existing components of the vehicle body structure 11 located above the EDU assembly 20, for example the support structure 17. The location of the torque reacting mount 60b facilitates mounting of the EDU assembly 20 to structurally strong locations of the vehicle body structure 11. The mass carrying mount 60a is orientated substantially perpendicularly to the torque reacting mount 60b. Put another way, a mounting axis of the mass carrying mount 60a is substantially perpendicular to a mounting axis of the torque reacting mount 60b. The orientation of the mass carrying mount 60a and the torque reacting mount 60b helps to enable the second flexible mount arrangement 60a, 60b to perform the dual function of acting as a mass carrier and a torque resistor because the load directions of the mass and torque of the EDU assembly 20 are substantially perpendicular. The mounting axis of the mass carrying mount 60a acts substantially vertically, in use. Put another way, the mounting axis of the mass carrying mount 60a is substantially perpendicular to the longitudinal axes a-a, b-b of both the vehicle 10 and the EDU assembly 20. The mounting axis of the torque reacting mount 60b is substantially lateral, or substantially parallel to the first flexible mounts 58a-f. Put another way, the mounting axis of the torque reacting mount 60b is substantially parallel to the longitudinal axis b-b of the EDU assembly 20, and substantially perpendicular to the longitudinal axis a-a of the vehicle body structure 11. The mass carrying mount 60a includes a plate 64 configured to extend along a plane substantially parallel to the longitudinal axis b-b of the EDU assembly 20. The plane is defined by the longitudinal axis b-b of the EDU assembly 20 and the longitudinal axis a-a of the vehicle 10. The plate 64 includes a substantially planar uppermost surface, in use. The plate 64 includes a resilient element configured to improve damping through the mass carrying mount 60a, thereby improving NVH performance of the mounting arrangement 50, in use. The resilient element may be an elastomeric body, for example a rubber block. A lowermost surface of the mass carrying mount 60a is mounted to the first EDU mounting bracket 52a. In particular, an uppermost surface of the first EDU mounting bracket 52a is mounted to the lowermost surface of the mass carrying mount 60a. The resilient element may be located at any suitable location on the mass carrying mount 60a, for example sandwiched between the uppermost and lowermost surfaces of the mass carrying mount 60a. The mass carrying mount 60a includes an auxiliary mounting arrangement 62a-e configured to mount the mass carrying mount 60a to the vehicle body structure 11. The auxiliary mounting arrangement 62a-f is illustrated in Figure 5 without the vehicle body structure 11. As illustrated in Figure 4, the mass carrying mount 60a is mounted to the support structure 17. As such, the first and second EDU mounting brackets 52a, 52b are suspended from the support structure 17 by the mass carrying mounts 60a, 60b. As the first and second EDU mounting brackets 52a, 52b are mounted to the EDU assembly 20 by the first mounting arrangement 58a-f, the mass of the EDU assembly 20 is suspended from the support structure 17 by the mass carrying mounts 60a, 60b and the first mounting arrangement 58a-c. Put another way, the one or more mounts of the first mounting arrangement 58a-c act as mass carrying mounts 58a-c. The auxiliary mounting arrangement 62a-d may be a plurality of bores located on the mass carrying mount 60a and each configured to receive a respective fastener. The bores of the mounting arrangement 62a-d extend through the uppermost surface of the plate 64, and the fasteners extend through the bores of the mounting arrangement 62a-d and through the vehicle body structure 11, for example through the support structure 17. In the embodiment shown in Figures 4 and 5, six mounting bores 62a-f are provided, with six corresponding fasteners extending therethrough. Four of the mounting bores 62a-d are located on each corner of the mass carrying mount 60a, and two mounting bores 62e, 62f are located between adjacent pairs of mounting bores 62a-d located at the corners. It shall be appreciated that the arrangement of the auxiliary mounting arrangement 62a-f illustrated in Figures 4 and 5 is one of many possible auxiliary mounting arrangements 62a-f that may be used to mount the mass carrying mount 60a to the vehicle body structure 11. By way of example, any suitable number of mounting bores and corresponding fasteners may be used, and the mounting bores may be located at any suitable location on the mass carrying mount 60a. As illustrated in Figure 5, the EDU assembly 20 includes at least one snubbing face 69 located on the first and / or second EDU mounting bracket 52a, 52b. In the embodiment of Figure 5, two snubbing faces 69 are provided in association with each of the mass carrying mounts 60a, 60c (i.e. a total of four snubbing faces 69). The at least one snubbing face 69 is at least partially aligned with the mass carrying mount 58a in a direction extending perpendicular to the longitudinal axis b-b of the EDU assembly 20. The snubbing face 69 helps to provide protection to the mass carrying mount 60a in the event of a lateral impact (i.e. an impact which causes a force in the lateral direction) to the vehicle 10, which may cause the mass carrying mount 60a to move laterally in a direction towards oraway from the EDU assembly 20. In the event of such an impact, the snubbing face 69 contacts the mass carrying mount 60a and exerts a force in an opposing direction to the movement of the mass carrying mount 60a towards the snubbing face 69. This helps to prevent significant moment / deformation of the mass carrying mount 60a, therefore helping to prevent permanent deformation of the second flexible mount arrangement 60a, 60c and reducing the likelihood of failure of the second flexible mount arrangement 60a, 60c. It shall be appreciated that as the mounting axes of the first flexible mounts 58a-f and the torque reacting mounts 60b, 60d are substantially parallel to the lateral direction, lateral impacts result in axial deformation (which respect to the mount axes) as opposed to side-to-side movement of the flexible mount with respect to the respective mounting axis. In embodiments where the mounting axes ofthe first flexible mounts 58a-f and / or torque reacting mounts 60b, 60d are non-parallel to the lateral direction, snubbing faces 69 may be provided in association with one or more of these flexible mounts. By way of example, snubbing faces 69 may be provided on the EDU assembly 20, for example on the EDU housing 19. The torque reacting mount 60b is of a similar configuration to the mounts ofthe first mounting arrangement 58a-f. As such, the torque carrying mount 60b includes an annular body at least partially surrounding a resilient element, and an inner sleeve located within the annular body and configured to receive a fastener therethrough. The resilient element is located between the annular body and the inner sleeve. As the torque reacting mount 60b is configured to dissipate torque and load transmitted therethrough, the torque reactor mount 60b may have a greater structural strength than the first flexible mounts 58a-f. A diameter ofthe torque reactor mount 60b may be in the range 10mm to 300mm, for example in the range 50mm to 200mm. It shall be appreciated that in alternative embodiments, the torque reactor mount 60b may be of an alternative embodiment. The torque reacting mount 60b includes an auxiliary mounting arrangement 66a-c configured to mount the torque reacting mount 60b to the vehicle body structure 11. In particular, as illustrated in Figure 4, the torque reacting mount 60b is mounted to an axial frame member 15a located on the left side 10a ofthe vehicle 10, and the torque reactor mount 60d is mounted to an axial frame member 15b located on the right side 10b of the vehicle 10. The auxiliary mounting arrangement 66a-c may be located on a mounting plate 68 extending radially around the torque reacting mount 60b. As illustrated in Figure 5, the auxiliary mounting arrangement 66a-c may be a plurality of bores surrounding the torque reacting mount 60b and each configured to receive a respective fastener. The fasteners extend through the mounting bores 66a-c and into corresponding bores in the vehicle body structure 11, for example in the first and second axial frame members 15a, 15b ofthe vehicle body structure 11. Figure 8 illustrates the steps of method 100 according to an embodiment ofthe present teachings. The method of mounting the EDU assembly 20 to the vehicle 10 will be described hereafter. The method includes the step S110 which includes providing the mounting arrangement 50 as described with reference to Figures 3 to 7. The mounting arrangement 50 includes the first EDU mounting bracket 52a, and in some embodiments the second EDU mounting bracket 52b. At step S120, the first EDU mounting bracket 52a is mounted to the EDU assembly 20 via the first flexible mount arrangement 58a-c ofthe first EDU mounting bracket 52a. The second EDU mounting bracket 52b is mounted to the EDU assembly 20 via the first flexible mount arrangement 58d-f ofthe second EDU mounting bracket 52b. At step S130, the EDU assembly 20 is mounted to the vehicle body structure 11 via the second flexible mount arrangement 60a-d. It will be appreciated that various changes and modifications can be made to the present invention without departing from the scope ofthe present application. It should also be noted that whilst the appended claims set out particular combinations of features described above, the scope of the present disclosure is not limited to the particular combinations hereafter claimed, but instead extends to encompass any combination of features herein disclosed.
