- FIG. 1 schematically illustrates a load transport vehicle 10, according to a particular and non-limiting embodiment of the present invention.
- the vehicle 10 corresponds for example to a vehicle with a combustion engine, with electric motor(s) or else a hybrid vehicle with a combustion engine and one or more electric motors.
- the vehicle 10 comprises a motorized block 100 arranged along a front portion of the vehicle 10, the motorized block comprising a motor unit 111, 112a, 112b driving a first set of drive wheels 121a, 121b, 122a, 122b, a battery 130a, 130b and a steering system.
- a single motor unit 111 is provided driving a front axle 113 associated with the front wheels 121a, 121b forming the first set of driving wheels.
- This design in particular allows greater robustness of the motorized block 100 and is easily adaptable from known architectures and/or parts of larger vehicles.
- each wheel 122a, 122b is respectively associated with a separate motor unit 122a, 122b, making it possible to reduce the volume and the weight of the motorized block 100 as well as to make the first set of driving wheels more maneuverable.
- This design is, for example, adapted from other light electric vehicles, whose sizing and expected loads remain similar.
- Figures 3 and 4 also illustrate a battery 130a, 130b disposed along an end portion of the motorized block 100, for example at the rear ( Figure 3) to facilitate its access from a user platform 400 described below, or at the front (FIG. 4) to facilitate its access in all designs of the vehicle 10.
- the arrangement of the battery 130a, 130b according to an end portion thus makes it possible to ensure easy access and in particular its exchange, for example so as to dispense 'a conventional recharge during prolonged use of the vehicle 10.
- the extreme arrangement is configured for the exchange of the battery, that is to say that the battery is removable. It is thus possible to remove the battery and recharge it, for example at home, then to reintroduce it into the motorized block 100.
- a lighting and/or light signaling device is additionally provided associated with the external structure of the motorized unit 100, so as to illuminate the front portion of the vehicle 10.
- a lighting device is for example also provided with cameras and/or sensors associated with a driving aid device integrated into the vehicle 10.
- the motorized unit 100 is also provided with a storage space 150 arranged along an upper portion.
- the storage space 150 is for example dimensioned according to the dimensions of the motorized unit 100 with respect to a total height of the vehicle 10, or even in consideration of a use of the vehicle 10, for example the presence of a user in the vehicle 10, for example a driver, the storage space 150 then being dimensioned so as to ensure the visibility of the user of the vehicle 10.
- the motorized block is equipped with an autonomous vehicle piloting device 10.
- the vehicle 10 thus corresponds for example to an autonomous vehicle with a determined level of autonomy, for example a level of autonomy higher than level 3 or level 4.
- the level of autonomy of the vehicle 10 corresponds for example to one of the 5 levels of the classification according to the American federal agency responsible for road safety or one of the 6 levels of the classification of the international organization of motor vehicle manufacturers.
- level 0 corresponding to a level without autonomy, under the full supervision of the driver
- 5 levels ranging from 1 to 5 corresponding to the levels of autonomy defined by the classification of the agency federal authority responsible for road safety:
- - level 0 no automation, the driver of the vehicle fully controls the main functions of the vehicle (engine, accelerator, steering, brakes);
- driver assistance automation is active for certain vehicle functions, the driver retaining overall control over the driving of the vehicle; cruise control is part of this level, like other aids such as TABS (anti-lock braking system) or ESP (programmed electro-stabilizer);
- TABS anti-lock braking system
- ESP programmed electro-stabilizer
- level 2 automation of combined functions, the control of at least two main functions is combined in the automation to replace the driver in certain situations; for example, adaptive cruise control combined with lane centering allows a vehicle to be classified as level 2, as does automatic parking assistance;
- level 3 limited autonomous driving, the driver can hand over complete control of the vehicle to the automated system which will then be in charge of critical safety functions; however, autonomous driving can only take place under certain determined environmental and traffic conditions (only on the motorway, for example);
- - level 4 complete autonomous driving under conditions, the vehicle is designed to carry out all the critical safety functions on its own over a complete journey; the driver provides a destination or navigation instructions but is not required to make himself available to regain control of the vehicle;
- a level of autonomy of the vehicle 10 for example greater than 4 additionally makes it possible to dispense with a driver, the vehicle 10 being able for example to be piloted remotely within a compatible urban zone, by example by communicating with a remote server using a V2X communication system, for example based on the 3GPP LTE-V (English “Long-Term Evolution” or French “Evolution à long terme”) or IEEE 802.11 p standards of ITS G5.
- each vehicle embeds a node to allow communication from vehicle to vehicle V2V (from the English “vehicle-to-vehicle”), from vehicle to infrastructure V2I (from the English “vehicle-to- - infrastructure”) and/or vehicle-to-pedestrian V2P (vehicle-to-pedestrian), the pedestrians being equipped with mobile devices (for example a smartphone) configured to communicate with the vehicles.
- vehicle to vehicle V2V from the English “vehicle-to-vehicle”
- V2I from the English “vehicle-to- - infrastructure”
- V2P vehicle-to-pedestrian
- the pedestrians being equipped with mobile devices (for example a smartphone) configured to communicate with the vehicles.
- the vehicle 10 advantageously embeds a set of sensors configured to obtain data on the environment of the vehicle 10, these data or a part of them being used in particular for driving the vehicle 10 in autonomous mode.
- This or these sensors correspond by example to sensors of one or more systems for detecting objects in the environment of the vehicle 10, the data obtained from this or these sensors making it possible, for example, to detect objects in the environment of the vehicle 10, for example in front of the vehicle 10.
- This or these object detection systems are for example associated with or included in one or more ADAS systems.
- the sensor(s) associated with these object detection systems correspond, for example, to one or more of the following sensors:
- each radar is adapted to emit electromagnetic waves and to receive the echoes of these waves returned by one or more objects, with the aim of detecting obstacles and their distances vis-à-vis the vehicle;
- a LIDAR sensor corresponding to an optoelectronic system composed of a laser transmitter device, a receiver device comprising a light collector (to collect the part of the light radiation emitted by the emitter and reflected by everything object located in the path of the light rays emitted by the transmitter) and a photodetector which transforms the collected light into an electrical signal; a LIDAR sensor thus makes it possible to detect the presence of objects situated in the emitted light beam and to measure the distance between the sensor and each detected object; and or
- one or more cameras associated or not with a depth sensor for acquiring one or more images of the environment around the vehicle located in the field of vision of the camera(s).
- the vehicle 10 also comprises a loading platform 200 arranged along a rear portion of the vehicle 10 and having a second set of wheels 210, for example a rear axle associated with a pair of wheels 210.
- the loading platform 200 is configured to receive a module 300, for example in a removable manner, the module 300 being placed on and/or removed from the loading platform 200 by the rear of the vehicle 10.
- the module 300 is for example designed so as to adapt the vehicle 10 to use for a variety of uses and services including, for example, last-mile delivery, nomadic sale of products and services, or certain technician professions. or craftsman.
- the module 300 belongs for example to a set of modules, each module 300 of the set of modules comprising:
- the module 300 corresponding for example to a container optimized for delivery;
- a workspace that is to say an equipped surface, for example arranged in the upper portion of the module 300, the equipment of the workspace being selected according to the use of the module 300 and associated for example with storage also arranged in module 300.
- the loading platform 200 has a flat body 220 extending horizontally, that is to say substantially parallel to the ground on which the vehicle 10 is traveling, as well as an extension 230 articulated arranged along a rear end of the body 220.
- the rear axle is for example arranged between the body 220 and the extension 230, or even according to a middle portion of the body 220 so as to ensure the balance of the vehicle 10.
- the extension 230 is advantageously configured to pass between a first position in which the extension extends in an extension of the body 220, that is to say also horizontally, and a second position in which the extension extends vertically from the rear end of the body.
- the extension 230 can be rotated relative to the rear end of the body 220 so as to raise the extension 230 until it forms a right angle with the body 220.
- This design thus makes it possible to adapt the loading platform 220 to different dimensions of the module 300 by providing greater security when the extension 230 is in the second position, the extension being for example locked so as to prevent a slipping of a module 300 light out of the vehicle 10.
- the motorized unit 100 is sized to drive the vehicle 10 at a maximum speed of 25 km/h, the first set of wheels 121a, 121b, 122a, 122b and the second set of wheels 210 being sized for road traffic.
- the vehicle 10 is for example dimensioned for the transport of loads of the order of 200 kg, allowing the transport of a variety of modules 300 adapted to the delivery or the itinerant sale of products and services, while being compatible with the driving in an urban environment, both in private parks and in urban centers restricted to motor vehicles, or even in compatible urban areas, for example equipped with an infrastructure allowing V2X communication with the vehicle.
- the first set of wheels 121a, 121b, 122a, 122b has for example a diameter of approximately 40 cm so as to ensure sufficient ground clearance of the vehicle 10. As illustrated in FIGS. 3 and 4, the first set of wheels 121a, 121b, 122a, 122b is also, for example, associated with shock absorbers 123a, 123b facilitating the crossing of obstacles and/or irregularities in the road, in particular in comparison with known solutions of electric handling trucks.
- the vehicle 10 further comprises a user platform 400 arranged between the motorized unit 100 and the loading platform 200.
- a user platform 400 is thus configured to receive a driver of the vehicle 10.
- the vehicle 10 is able to circulate without boarding a driver and can thus be sized without requiring space dedicated to the reception of the driver or in such a way as to optimize the space dedicated to receiving the module 300, in particular when the vehicle 10 carries a module 300 dedicated to delivery operations.
- An autonomous vehicle 10 is also designed comprising a user platform 400, allowing the latter to move with the equipment of the module 300 over short journeys.
- the motorized block 100 has a set of controls 140 extending from the motorized block 100 in the direction of the user platform 400, that is to say in the direction of a driver of the vehicle 10, the set of controls 140 allowing control of the motor unit 111, 112a, 112b and the steering system.
- the set of controls 140 comprises for example a handlebar 141 and/or a man-machine interface 142 arranged within reach of the driver of the vehicle 10.
- control of the vehicle 10 is more or less assisted depending on the design of the set of controls 140, or even controlled entirely in a non-mechanical way, for example with a direction controlled by a "steer-by-wire” system (in French “direction by cables”) or “drive-by-wire” (in French “ driving by cables”) making it possible to transcribe instructions received via the man-machine interface 142 into commands of the engine group 111, 112a, 112b and of the steering system.
- the motorized block 100 and the user platform 400 are sized for the driver to be standing on the user platform 400.
- the set of controls 140 is for example arranged at a height facilitating interaction when the driver is standing , and the motorized block 100 is dimensioned so as to ensure the visibility of the driver, the storage space 150 extending for example up to a height limit making it possible to guarantee its visibility.
- the length of the user platform 400 as illustrated in FIG. 2 is reduced in comparison with solutions providing for a seated driver, thus making it possible to increase the space available for receiving the module 300 and therefore to propose a vehicle 10 compact maximizing transportable volume.
- Driver installation is also simplified and suitable for short last mile journeys, without requiring prolonged discomfort.
- the vehicle 10 has a length of between 1.90 m and 2.50 m and a width of between 0.90 m and 1.10 m, making it possible to simplify the parking of the vehicle 10 opposite of the urban infrastructure and being compatible with the reboarding of a module 300 of substantial volume, for example a module 300 with a volume of approximately 600 L for a height of approximately 90 cm.
- the present invention provides a load transport vehicle, for example an autonomous electric vehicle, adapted to the constraints of last mile journeys by proposing a dimensioning adapted to road traffic and optimizing the useful volume of loading of a module adaptable to the delivery, sale or provision of various services.
