- the motor vehicle 100 can be a motor vehicle of any type, in particular a passenger vehicle, a utility vehicle, a truck or even a public transport vehicle such as a bus or a shuttle.
- the motor vehicle 100 is an autonomous vehicle and will be referred to as an “autonomous vehicle” in the remainder of the description. This illustration is therefore made on a non-limiting basis.
- the motor vehicle could be a non-autonomous vehicle, equipped with a driving assistance system, in particular a driving assistance system corresponding to a level greater than or equal to level 2 of autonomy, i.e. that is to say corresponding to a partial autonomy of the vehicle.
- the autonomous vehicle 100 mainly comprises the following elements:
- a calculation unit 8 comprising a microprocessor 81, a local electronic memory 82 and communication interfaces 83 allowing the microprocessor 81 to communicate with the sensors 1, the communication systems 2, the man-machine interface 3, the system 5 for processing perception data, the system 6 for decision-making, and the system 7 for controlling the movement of the vehicle.
- the sensors 1 of the environment of the autonomous vehicle 100 can comprise a set of cameras and/or lidars and/or radars for observing the 360-degree environment around the autonomous vehicle 100. They can further comprise a GPS and a unit inertial measurement devices used for locating the autonomous vehicle 100. The data from the sensors 1 are transmitted to the system 5 for processing perception data.
- Communication systems 2 include vehicle-to-vehicle communication systems (V2V systems) or vehicle-to-infrastructure communication (V2i systems) enabling vehicles to exchange information with each other and with the infrastructure, particularly with regard to weather conditions.
- V2V systems vehicle-to-vehicle communication systems
- V2i systems vehicle-to-infrastructure communication
- the man-machine interface 3 is intended for the driver or user of the autonomous vehicle 100. It allows the driver or user of the autonomous vehicle 100 to evaluate the behavior of his own vehicle or of a surrounding vehicle. It also makes it possible to inform the driver of the vehicle when responsibility for controlling his vehicle is assigned to him following a failure of at least one automated system.
- the actuators 4 implement the movement of the autonomous vehicle 100; they include an engine torque actuator, a brake actuator and a steering wheel rotation actuator.
- the perception data processing system 5 processes the data coming from the sensors 1 and from the communication systems 2, and constructs a representation of the environment of the autonomous vehicle 100.
- the system 5 outputs the position of the vehicle and a description of all relevant objects around it.
- the decision-making system 6 receives the data from the perception data processing system 5, which informs it of the current situation of the vehicle and its environment. Depending on these data, the system 6 adapts the behavior of the vehicle to the current situation. In particular, the system 6 can determine a decision of the autonomous vehicle 100, relating for example to a maneuver to change lanes, and/or to stay on the lane with a change of speed.
- the system 6 comprises a navigation system whose role is to generate the movement and the behavioral planning of the vehicle. It acts before the vehicle motion control system 7 to adapt the response of the vehicle according to the current scenarios.
- the vehicle motion control system 7 mainly consists of a longitudinal control subsystem, a lateral control subsystem and the chassis. System 7 generates commands to minimize an error between the real trajectory of the vehicle and the trajectory defined by the navigation, for example for lane following, speed following, etc.
- the perception data processing system 5, the decision-making system 6 and the vehicle movement control system 7 are capable of receiving rewards or notes from the microprocessor 81 .
- the autonomous vehicle 100 therefore comprises an ordered set ENS of automated systems, the ordered set comprising, in order, the following systems: the vehicle movement control system 7, then the decision making 6, then the perception data processing system 5.
- Figure 2 is an alternative representation of a motor vehicle equipped with a supervision device according to the invention.
- the computer 81 makes it possible to execute software comprising the following modules which communicate with each other:
- a supervision activation module 811 which communicates with the communication systems 2, the man-machine interface 3 and the local memory 82, - a module 812 for supervising an automated system, which communicates with the perception data processing system 5, the decision-making system 6, the vehicle movement control system 7 and the local memory 82,
- module 813 for updating an automated system which communicates with the perception data processing system 5, the decision-making system 6, the vehicle movement control system 7 and the local memory 82,
- module 814 for transferring driving to a human driver, which collaborates with the man-machine interface 3 and the local memory 82.
- the method comprises four steps E1 to E4.
- a first step E1 the supervision of the ordered set ENS of automated systems is activated.
- the activation of supervision is automatic. For example, it is performed when the autonomous vehicle 100 is started, then the set of subsystems is then periodically supervised, at a period P which can be fixed or dependent on the navigation context of the vehicle.
- step E1 it is possible for example to use a time delay TEMPO associated with step E1.
- the time delay is recorded in the local memory 82. It can assume two states: a so-called inactive state, and a so-called active state. By default the timer is in the inactive state. When a timer is started, then it goes into the active state. Then when the duration of the timer has elapsed, the timer goes into the inactive state. In the first embodiment of step E1, the state of the time delay TEMPO is tested.
- the TEMPO time delay is activated by assigning it a duration P corresponding to the supervision period. The time delay then switches to the active state for a duration P. We then move on to step E2.
- the activation of the supervision can comprise a reception of an evaluation of a behavior of the autonomous vehicle 100 resulting either from the man-machine interface 3, or from communication systems 2.
- the genre of the vehicle control 100 is evaluated.
- the genre of the vehicle control is recorded and updated in the local memory 82.
- the vehicle control can be
- step E1 if the vehicle is controlled by the ENS set of at least two automated systems. If the control of the vehicle is of the first kind T1, this means that the evaluation of a behavior of the vehicle is intended for a human driver of the vehicle. A score is then assigned to the human driver based on the assessment of EC behavior. It is transmitted to it via the man-machine interface 3. Then we loop back to step E1.
- control of the vehicle is of the second type T2
- the automated systems of the ENS set are successively supervised, the order of supervision of the systems being fixed. In the embodiment of the ENS assembly described, this amounts to first supervising the vehicle motion control system 7, then the decision-making system 6, then the perception data processing system 5.
- the supervision of an automated system Si comprises two sub-steps:
- the processing carried out in the sub-steps E21 and E22 depend on the evaluated subsystem Si.
- the sub-steps E21 and E22 are iterated over the different systems Si.
- a positive, negative or zero score is assigned as a function of the calculated difference.
- the decision-making system 6 in the sub-step E21, it is possible to check whether a decision defined by the decision module 6 respects the constraints determined by the perception system 5. For example, it is possible check whether the decision respects the configuration of the surrounding traffic, the state of the traffic lights, etc. Then, in the sub-step E22, if the decision respects the configuration of the surrounding traffic, then a positive or zero score is assigned to the module decision-making module 6. Otherwise, a negative score is assigned to the decision-making module 6.
- the sub-step E21 it is possible to check the consistency between the current perceptions provided by the perception system 5 at the time T of supervision, and the perceptions provided by the system of perception 5 at a previous instant T-dT. For example, one can check whether ghost tracks have appeared between the instants T-dT and T, or one can detect an uncertainty on the localization of a vehicle or an object between the instants T-dT and T. One can moreover detect images altered due to bad weather conditions. Then, in sub-step E22, depending on the results of sub-step E21, a positive or negative or zero rating is assigned to the perception system.
- each automated system Si supervised in step E2 obtains a positive, negative or zero score Ni.
- the notes Ni obtained are recorded in the local memory 82 in order to be processed during the subsequent execution of step E3 for updating at least one automated system Si.
- step E2 is interrupted as soon as an automated system Si obtains a negative score Ni.
- This preferential mode of execution of step E2 is illustrated by FIG. 4 and described below.
- a first step 140 it is tested whether the vehicle movement control system 7 has achieved its objectives:
- a negative reward is transmitted to the system 7 and one goes directly to step E3.
- step 150 it is tested whether the decision-making system 6 has achieved its objectives:
- a neutral reward is transmitted to the system 6; then continues on a sixth step 160 and
- a negative reward is transmitted to the system 6 and one goes directly to step E3.
- step 161 a negative reward is transmitted to the perception data processing system 5 and the process continues directly with step E3,
- step 162 a neutral reward is transmitted to the system 5; then goes on to step E4 of transfer of driving to a human driver.
- step E2 applied to the system for controlling the movement of the vehicle 7
- step E3 for updating of the system 7 for controlling the movement of the vehicle without carrying out supervision either of the system 6 of decision-making, or of the system 5 of perception.
- step E2 applied to the decision-making system 6
- the decision-making system 6 obtains a negative score
- step E3 for updating the system 6 of decision-making without carrying out supervision of the system 5 of perception.
- step E1 When a negative evaluation of a behavior of the autonomous vehicle 100 (coming from the man-machine interface 3 or from the communication systems 2) has been processed in step E1, it is expected to determine in step E2 which automated system If is causing the negatively rated behavior. However, it may happen that no automated system Si obtains a negative score when performing step E2. We are thus in a situation where the supervision of the systems carried out in step E2 does not determine any possible source of the behavior of the autonomous vehicle, and therefore no means of correcting the behavior evaluated as negative. In this case, we move on to step E4 of transferring driving to a human driver.
- step E3 at least one automated system Si of the ordered set ENS is updated according to a score Ni assigned to the at least one automated system Si.
- Step E3 includes the implementation of an adaptation of each automated system Si having obtained a score Ni during the execution of step E2.
- the adaptation includes setting implementation of a reinforcement learning algorithm RLi and/or the adaptation comprises the implementation of a switching system SWj.
- the term “adaptation” of a system Si designates a learning process or an improvement or an update of the system Si by taking into account a score Ni obtained during the execution of step E2 .
- Figure 5 illustrates the principle of an RLi reinforcement learning algorithm applied to a trained Si system.
- the system Si receives information on the state of an environment Ej(t), comprising a set of data describing a current situation. From this information, the system Si selects an action to be performed A(t), which modifies the state of the environment (the new state being Ei(t+dt)) and generates a reward Ri(t+dt) for the system Si.
- the objective of such an algorithm is to maximize the reward Ri after a certain number of iterations of the algorithm.
- the learning algorithm RLi could use a learning method of the Q-Learning type, which allows the system Si to learn a strategy to determine which action To perform in each state Ei of the system. It works by learning a function Qi which makes it possible to determine the potential gain, Qj(Ej(t), (t)), i.e. the long-term reward brought by the choice of an action Aj(t) in a state Ej(t) following an optimal policy.
- Qj(Ej(t), (t) i.e. the long-term reward brought by the choice of an action Aj(t) in a state Ej(t) following an optimal policy.
- One of the advantages of the learning method by Q-learning is that it does not depend on the definition of an evolution model or a control strategy previously defined by the user but is based directly on the interaction of the system with its environment and the reward received at each step.
- the adaptation of an autonomous system Si includes the implementation of a learning algorithm RLj
- the positive or zero score obtained by an automated system Si during the execution of step E2 makes it possible to improve the robustness of the system, in particular by saving in the local memory 82 the parameters of the system Si applied during the scenario associated with obtaining the positive or zero score, in particular by saving the data received at the input of the system and the data provided in exit from the Si system.
- the adaptation of an autonomous system Si can include the implementation of a switched system SWi.
- a switching system SWi is composed of a set of subsystems SSWk and a logic law L (or switching controller L) which indicates which subsystem SSWk is active.
- a Q-learning algorithm could cooperate with an Li switching controller designed for the purpose of supervising the SW switching system.
- a first type of adaptation implementing a reinforcement learning algorithm RLj
- a second type of adaptation implementing a switching system SW
- the search for stability of the system Si For example, in the case of a system 7 for controlling the movement of the vehicle 7, the stability of the system is essential for reasons of safety of the movement of the vehicle.
- an adaptation of the second type will preferably be used, that is to say an adaptation implementing an SW switching system.
- the system Si to be adapted manages a large number of data
- the use of a reinforcement learning algorithm is particularly advantageous for adapting the decision-making system 6 .
- this type of algorithm makes it possible to manage a large number of physical and measured data, then to evaluate the links between the data describing the environment of the vehicle and a decision taken by the decision-making system 6 .
- RLi reinforcement learning algorithms offer an alternative solution to modeling; they make it possible to manage the increasing complexity of the system by providing an intermediate solution comprising a first part of exploratory processing and a second part of data exploitation processing, the first and second parts together making it possible to infer a behavior of the system Si.
- FIGS. 6 to 9 An example of implementation of a supervision method according to the invention is described by FIGS. 6 to 9.
- the simulation described relates to an autonomous lane change of the autonomous vehicle 100.
- the graph G1 of figure 6 represents
- the lateral distance expressed in meters between the position 301, 302, 303 of the autonomous vehicle and the target trajectory 201 .
- the autonomous vehicle 100 initiates a lane change maneuver when it is located at a lateral distance from the target trajectory 201 equal to 3 meters, as represented by point A in FIG. 6.
- the perception data processing system 5 identifies the presence of a truck located at an ordinate 202 equal to ⁇ 1 meter, that is to say at a lateral distance of 1 meter from the target trajectory and at a lateral distance 4 meters from the autonomous vehicle 100 at the start of the maneuver (that is to say at point A).
- the decision-making system 6 transmits to the movement control system 7
- the objective of the movement control system 7 is to follow the trajectory smoothly (in particular by applying a low steering force) while respecting the lateral constraints requested.
- the system 7 is evaluated according to the following criteria:
- step E3 the learning of system 7 is reinforced by processing the positive note Ni.
- the learning of system 7 is based on the use of a switching system SWi, which can switch between three different versions 71, 72, 73 of system 7.
- Figure 7 represents, in a G2 graph:
- Figure 8 represents, in a G3 graph:
- FIG. 9 represents, in a graph G4, the score assigned 601, 602, 603 respectively to each of the first, second and third versions 71, 72, 73 of system 7.
- Figures 6 and 7 illustrate the fact that the first version 71 of the system 7 did not allow the autonomous vehicle 100 to respect the lateral limit 203. In the step E22, the first version 71 of the system 7 therefore obtains a score N71 strongly negative, notably -6, as shown in Figure 9.
- step E3 the note N71 is then transmitted to the system 7 which is thus informed that it must be improved.
- a second version 72 of system 7 is then used instead of the first version 71.
- Figures 6 and 7 illustrate the fact that the second version 72 of system 7 allowed the autonomous vehicle 100 to respect the lateral limit 203.
- FIG. 8 illustrates the fact that the second version 72 has exceeded the authorized limit in terms of steering speed 502.
- the second version 72 of the system 7 therefore obtains a slightly negative rating N72, as illustrated by Figure 9.
- step E3 the note N72 is then transmitted to the system 7 which is thus informed that it must be improved again.
- a third version 73 of system 7 is then used instead of the second version 72.
- Figures 6 and 7 illustrate the fact that the third version 73 of system 7 has enabled the autonomous vehicle 100 to respect the lateral limit 203.
- Figure 8 illustrates the fact that the third version 73 has only temporarily exceeded the authorized limit in terms of steering speed 502.
- the third version 72 of system 7 therefore obtains a positive note N73, as shown in figure 9.
- control of the vehicle is transferred to a user of the autonomous vehicle 100.
- the automated systems Si are then no longer active.
- the genre of the vehicle control is then updated in the local memory 82, as being of the first genre T1.
- the supervision method according to the invention makes it possible to evaluate, validate and improve any autonomous driving assistance system (ADAS system) or any automated system of an autonomous vehicle.
- ADAS system autonomous driving assistance system
- the supervision process assigns individual ratings (or rewards) to the behavior of each supervised system, these ratings being able to be positive or negative.
- the first effect of this is to determine the source of any malfunction and thus to take measures to individually secure the operation of each supervised system.
- This has the second effect of improving the operation of each supervised system by memorizing the data resulting from the experience of the autonomous vehicle, in particular when a supervised system obtains a positive score.
- the experience of each supervised system can be capitalized using, for example, a reinforcement learning algorithm or a switching system.
- the supervision method according to the invention can be implemented in different circumstances.
- supervision can intervene during the calibration phase of the autonomous vehicle, to train each automated system of the autonomous vehicle 100 before the sale of the vehicle.
- the supervision can intervene during the current use of the autonomous vehicle 100 by a user.
- Supervision can then be periodic.
- the supervision can be triggered punctually following a negative evaluation of a behavior of the autonomous vehicle 100, the evaluation possibly coming from data from V2V or V2i networks, or from a man-machine interface of the autonomous vehicle 100 .
- the supervision When it generates a negative score, the supervision signals a problem to be solved and leads to an improvement of the supervised system and/or the transfer of driving to a user of the autonomous vehicle 100.
- the supervision method also applies to a human driver of the autonomous vehicle 100.
- the supervision method transmits ratings to the human driver via a man-machine interface, these ratings being able to be determined according to evaluations issued by a surrounding vehicle or surrounding infrastructure.
- the supervision method according to the invention thus has several advantages.
- the supervision method according to the invention improves vehicle performance, reliability and safety, in particular by improving the vehicle's adaptability to normal and critical situations.
- the supervision method according to the invention enables the vehicle to improve its operation over the course of its use, by acquiring knowledge of the situations encountered.
- the supervision method according to the invention is applicable to any automated system equipping the vehicle. It can also apply to a human driver of the vehicle.
