Description

Title of the invention: Method for adapting the functionalities of a vehicle to the driver's control. Technical field

[0001] The invention is in the technical field of vehicles, in particular motor vehicles, and relates more particularly to a method for estimating the driving performance of a driver, in order to adapt the functionalities of the vehicle to the control that its driver has over it. Previous technique

[0002] Each model of motor vehicle has its own performance levels, whether in terms of engine power, road handling, braking power, grip, etc. This is also the case for different versions of the same vehicle model, for which the engine power, wheel size, weight, etc. may differ, so that drivers do not really know the operating limits of their vehicle, and do not take full advantage of it.

[0003] Furthermore, an overly powerful vehicle can prove difficult for an inexperienced driver to operate, potentially causing discomfort for passengers and increasing the risk of accidents. Conversely, a driver who fully utilizes the vehicle, particularly by being aware of its dynamic operating limits, will be more efficient in maneuvering, drive more safely, and react more effectively to hazards on the road.

[0004] There is therefore a need for a method to adapt the functionalities of a vehicle to the driver's skill level. The method also aims to allow the driver to progressively acquire a detailed understanding of the vehicle's performance. Advantageously, the method makes it possible to adapt the vehicle's power to the driver's skill level, particularly for "sports" cars, which can be complex to handle for less experienced drivers. Summary of the invention

[0005] To this end, the present invention describes a method for adapting the functionalities of a vehicle to the driver's control over it. The vehicle in question comprises a plurality of on-board sensors, configured to allow the acquisition of data relating to its movement and use. The method according to the invention comprises: - a first step (21) of selecting a challenge from among one or more predefined challenges aimed at assessing the driver's mastery of the vehicle, - a step (22) in completing the challenge, comprising: • a substep (222) of acquiring data relating to the movement and use of the vehicle during said challenge, acquired from at least one of said on-board sensors, • a substep (223) of stopping the challenge, when a stopping condition associated with the challenge is met, • a substep (224) of processing data relating to vehicle movement and use acquired during said predefined challenge, in order to verify whether at least one objective associated with said predefined challenge has been achieved, - a step (23) of unlocking vehicle functionalities, said unlocking being conditional upon the prior achievement of objectives for at least one of said one or more predefined challenges.

[0006] Advantageously, step (22) of fulfilling the challenge includes an initial substep (221) of validating a prerequisite.

[0007] According to different embodiments of the invention, step (23) of unlocking vehicle functionalities may include at least one of the following: - unlocking one or more new challenges; - unlocking new vehicle ambiences; - unlocking rewards; - unlocking vehicle performance levels; - unlocking the possibility of deactivating driver assistance systems vehicle.

[0008] According to a particular embodiment of the invention, the predefined challenges allow the driver's driving skills to be evaluated in at least one of the following categories: agility, endurance, and control of the vehicle's power.

[0009] According to different embodiments of the invention, the predefined challenges include at least one of the following: - a challenge over a set period, starting from a standstill and reaching a given speed. - a challenge over a set time, starting from a standing start, over a given distance. - a challenge involving braking for a specific duration from a given speed up to a certain speed inferior, - a challenge involving acceleration over a given distance, - a challenge regarding longitudinal acceleration, - a challenge involving lateral acceleration, - a challenge based on the number of turns completed over a given distance or duration, - a challenge based on an average steering wheel angle over a given distance or duration, - a challenge on average lateral acceleration without driving aids on a distance or a given duration, - a challenge involving a certain number of turns completed using only regenerative braking over a given distance or duration, - a challenge involving measuring the energy consumed over a given number of turns, - a challenge involving a measurement of the instantaneous energy consumed over a given number of turns, - a challenge involving measuring the energy consumed over a given distance, - a challenge based on a distance covered for a given battery discharge level given electrical current and a given time.

[0010] According to a particular embodiment of the invention, a points-based reward system is implemented, with one or more points being awarded to the driver upon achieving a goal associated with a challenge. In this case, step (23) of unlocking vehicle functionalities is performed when a certain point threshold is reached.

[0011] The invention also relates to a vehicle comprising a plurality of on-board sensors configured to enable the acquisition of data relating to its movement and use, and comprising at least one computer configured to process said data, wherein the computer is configured to implement a method of adapting the functionalities of a vehicle to the control that its driver has over it as described above.

[0012] Advantageously, the vehicle is of the electric type.

[0013] According to different embodiments of the invention, the sensors on board the vehicle according to the invention comprise at least one of a speed sensor, a wheel rotation speed sensor, a distance travelled sensor, a brake pressure sensor, a battery power output sensor, a consumption sensor, a longitudinal force sensor, a lateral force sensor, and a steering wheel angle sensor. Brief description of the drawings

[0014] The invention will be better understood and other features, details and advantages will become clearer from the following description, given by way of non-limiting reason, and from the accompanying figures, given by way of example.

[0015] [Fig-1] Fig. 1 represents very schematically the different components of a motor vehicle.

[0016] [Fig.2] Fig.2 schematically represents the sequence of steps in the process of adapting the functionalities of a vehicle to the control that its driver has according to the invention.

[0017] Identical references may be used in different figures when they refer to identical or comparable elements. Description of the implementation methods

[0018] In the following description, the method according to the invention is described in relation to a motor vehicle. However, it applies equally to any type of motor vehicle: motorcycle, truck, boat, etc.

[0019] Figure 1 schematically represents the various components of a motor vehicle. Typically, such a vehicle consists of a chassis, a passenger compartment, and wheels 101 connected to the chassis by a suspension mechanism. The front wheels are steerable and controlled by a steering wheel 102, which is operated by a driver from inside the vehicle. The vehicle is propelled by torque or power delivered to the drive wheels by a powertrain 103, which may be internal combustion, hybrid, or electric. The vehicle also includes a battery 104, the size and position of which may vary, particularly depending on the type of powertrain.

[0020] The vehicle further comprises at least one control unit, connected to a front wheel steering position sensor, which may be located on a steering rack, to a front wheel rotation speed sensor providing an image of the vehicle's actual speed and longitudinal acceleration, to a yaw rate sensor, or an estimator of this quantity, which is the vehicle's rotational speed around its center of gravity along a vertical axis, and to a lateral acceleration sensor at the vehicle's center of gravity, or an estimator of this quantity. The vehicle may also comprise an inertial measurement unit and satellite positioning means.The vehicle may also include a sensor for the current delivered by the traction battery, or an estimator of this quantity, and a sensor for measuring the power and / or torque supplied by the motor, or an estimator of these quantities. Other sensors are also present in a motor vehicle: pressure sensors for the hydraulic braking system, oil pressure sensors, rain, light, and temperature sensors, etc. Finally, the vehicle has a central display 107 and controls that allow the vehicle to be operated and various information to be displayed.

[0021] It is known to vary several operating parameters of the vehicle, such as the characteristics of the shock absorbers or the engine control laws, in order to effect a change in the dynamic behavior of the vehicle, so as to have a sporty behavior by favoring the responsiveness of the systems, or an economical behavior by favoring low consumption, which makes it possible to offer very different driving sensations.

[0022] The various sensors on board the vehicle make it possible to collect a multitude of data relating to the driver's actions and the use of the vehicle. This data can then be processed by one or more computers 105 and 106 on board the vehicle, which communicate via a CAN data bus (English acronym for Controller Area Network).

[0023] However, it is impossible to quantify the driver's control of their vehicle by observing the data acquired during their journeys. Indeed, the data collected on daily commutes does not allow for an assessment of the driver's performance when faced with a difficult situation. Therefore, it is currently impossible to adapt the vehicle's features to the driver's level of control.

[0024] To address this problem, the proposed invention describes a method in which the driver is subjected to one or more predefined challenges designed to assess their skills in specific areas, within a vehicle operating mode specifically dedicated to this purpose. By choosing to activate this specific operating mode, the driver is aware that their driving behavior during certain challenges may be incompatible with sharing the road with other vehicles, and that it is preferable to implement them in an area where traffic is limited and controlled, such as a private road or a racetrack.

[0025] The driver's performance in driving the vehicle can be grouped into different categories. For example, these categories could be the driver's agility, the driver's endurance, and their control of the vehicle's power.

[0026] A driver's agility is their ability to maneuver their vehicle with precision. The aim here is to help the driver better control the vehicle's handling, in order to be more able to avoid loss of control, maintain the vehicle's trajectory in curves, and be more effective in performing evasive maneuvers.

[0027] A driver's endurance is their ability to adopt responsible driving practices. This involves encouraging the driver to minimize their energy consumption in the broadest sense: consumption of batteries, gasoline, tires and / or brakes.

[0028] A driver's mastery of vehicle power is their ability to utilize the vehicle's full power. This involves enabling the driver to better understand and control the power of the vehicle's powertrain, in order to be more efficient when overtaking or merging into traffic, and to better control the vehicle's braking power, in order to be more effective, particularly in emergency braking situations.

[0029] Thus, the invention relates to a method for adapting the functionalities of a vehicle to the driver's control over it. The method according to the invention uses, in particular, data collected by a plurality of sensors installed in the vehicle and configured to deliver information relating to the vehicle's movement and use to a computer. The computer may be one of the computers installed in the vehicle, or a computer specifically dedicated to implementing the invention, using any electronic component or combination of components for processing the acquired data, such as, for example, a processor, a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), a microcontroller, etc., connected to data storage means.

[0030] Fig. 2 is a schematic representation of the sequence of steps of a process for adapting the functionalities of a vehicle to the control that its driver has according to an embodiment of the invention.

[0031] The method includes a step 21 of selecting a challenge from among one or more predefined challenges designed to assess the driver's mastery of the vehicle in a specific skill area. This step corresponds to the vehicle displaying, on a graphical interface, or HMI (acronym for Human-Machine Interface), for example the dashboard 107, one or more challenges available to the driver, as well as the objectives to be achieved to complete them, and then to the driver's selection of the challenge to be completed. Each challenge is associated with a stopping condition.

[0032] The method according to the invention then comprises a step 22 of carrying out the challenge, which can be broken down into different sub-steps: - an optional substep 221 for validating one or more prerequisites for implementing the test. For example, a challenge to measure acceleration requires ensuring that the vehicle is stationary or at a predefined speed, based on vehicle speed or wheel rotation speed information. If the prerequisite for performing the test is met, the challenge is launched, possibly after a countdown. Otherwise, the challenge is pending, and an informational message may be displayed. Some challenges, such as a distance challenge, do not require prior validation of a condition, in which case the challenge is launched directly; - a sub-step 222 for acquiring data relating to the movement and use of the vehicle during the challenge, acquired from at least one of the on-board sensors. The data acquired depends on the challenge being carried out. By For example, a challenge designed to measure acceleration requires acquiring the vehicle's speed. Some challenges also require measuring the challenge's execution time. The acquired data can be processed in real time to indicate to the driver, via a display, their progress towards the challenge's objective during its execution; - a sub-step 223 of stopping the challenge, when the stopping condition is met. For example, for a challenge aimed at measuring acceleration, the stopping condition may correspond to a time elapsed. For other challenges, the stopping condition may correspond to the distance traveled by the vehicle; - A substep 224, executed after the challenge, processes the vehicle movement and usage data acquired during the challenge to verify whether at least one objective associated with the predefined challenge has been achieved. For example, for a challenge measuring acceleration, this step might include verifying the vehicle's speed after a specified time and comparing this speed with a predetermined target speed. Completed challenges and their corresponding objectives are recorded.

[0033] Step 22 thus allows the driver and their vehicle to be confronted with objectives on challenges in order to precisely quantify their performance in specific skill areas. Advantageously, several objectives can be defined for the same challenge, in order to weight the degree of success in the challenge.

[0034] The challenges are pre-programmed and stored in the vehicle. Advantageously, they can be adapted to the vehicle model, its engine, its equipment level, etc. They may require the use of data transmitted by various vehicle sensors, such as a speed sensor, a wheel rotation speed sensor, a distance traveled sensor, a braking sensor, a battery power output sensor, a consumption sensor, a longitudinal force sensor, a lateral force sensor, a steering wheel angle sensor, etc.

[0035] Advantageously, the list of challenges can be modified by a remote or local software update.

[0036] Examples of possible challenges are listed below, by way of non-limiting illustration, grouped here by categories of evaluated performance: - for assessing the driver's control of the vehicle's power: • A timed challenge from a standstill to a given speed, for example, from 0 km / h to 100 km / h. This challenge aims to assess the driver's ability to perform a rapid acceleration. It requires validation a prerequisite condition on the vehicle's speed (or equivalently the wheel rotation speed), and the acquisition of the vehicle's speed during the challenge. The stopping condition relates to the vehicle's speed, and the achievement of the objective is evaluated based on the time taken to complete the challenge; • A timed challenge starting from a standstill over a given distance, for example, 400 meters or 1000 meters. This challenge also aims to assess the driver's ability to achieve strong acceleration. It requires the validation of a prerequisite condition regarding vehicle speed, and the acquisition of the distance covered during the challenge. The stopping condition relates to the distance covered, and the achievement of the objective is evaluated based on the time taken to complete the challenge; • A challenge involving braking from a given speed to a lower speed, for example, from 100 km / h to a complete stop. This challenge aims to assess the driver's ability to perform a powerful braking maneuver. It requires the vehicle to meet a prerequisite speed at the start of the challenge, and the vehicle to reach that speed during the challenge. The stopping condition relates to the vehicle's speed, and achievement of the objective is assessed based on the time taken to complete the challenge; • A challenge involving acceleration over a given distance, for example, 10 km. This challenge aims to assess the driver's ability to achieve high accelerations. It does not necessarily require the fulfillment of a prerequisite condition and requires the acquisition, during the challenge, of the vehicle's acceleration (measured from an acceleration sensor, an inertial measurement unit, a satellite positioning device, or derived from the vehicle's speed or the wheel rotation speed). The stopping condition relates to the distance traveled, and achievement of the objective is assessed based on the average acceleration measured during the challenge; for assessing driver agility: • A challenge involving the longitudinal acceleration of the vehicle. This challenge aims to assess the driver's ability to achieve powerful acceleration. It does not necessarily require validation of a prerequisite condition and requires the acquisition, during the challenge, of the vehicle's longitudinal acceleration (e.g., measured in m / s² or g). The stopping condition relates to a time elapsed, and the achievement of the target time. the objective is evaluated based on the maximum longitudinal acceleration observed during the challenge; • A challenge involving lateral acceleration of the vehicle. This challenge aims to assess the driver's ability to perform a sudden change of trajectory. It does not necessarily require validation of a prerequisite condition, and requires the acquisition of lateral acceleration of the vehicle during the challenge. The stopping condition relates to a time elapsed, and achievement of the objective is assessed based on the maximum lateral acceleration observed during the challenge; • A challenge involving a specific number of turns completed over a given distance (or time), for example, 10 km (or 10 minutes). This challenge aims to assess the driver's ability to perform a series of trajectory changes. It does not necessarily require validation of a prerequisite condition and requires the driver to acquire, during the challenge, the ability to control the vehicle's lateral acceleration or steering angle. The stopping condition relates to a time elapsed (or, respectively, a distance traveled), and achievement of the objective is assessed based on the number of turns completed during the challenge; • A challenge based on the average steering wheel angle over a given distance (or time), for example 10 km (or 10 minutes). This challenge aims to assess the driver's ability to navigate a series of tight turns. It does not necessarily require validation of a prerequisite condition and requires the driver to acquire the steering wheel angle during the challenge. The stopping condition relates to a time elapsed (or respectively a distance traveled), and achievement of the objective is assessed based on the average steering wheel angle during the challenge; • A challenge involving average lateral acceleration without driver assistance over a given distance (or time), for example 10 km (or 10 minutes). This challenge aims to assess the driver's ability to navigate a series of tight corners without driver assistance. It does not necessarily require validation of a prerequisite condition and requires the acquisition, during the challenge, of the vehicle's lateral acceleration or steering wheel angle. The stopping condition relates to a distance traveled (or, respectively, a time elapsed), and achievement of the objective is assessed based on the average lateral acceleration measured during the challenge; for assessing driver endurance: A challenge involving a number of turns completed using only regenerative braking over a given distance (or time), for example, 30 km (or 30 minutes). This challenge aims to assess the driver's ability to use the vehicle's regenerative braking to slow down when entering turns, thereby recharging the battery and conserving the vehicle's brakes. It may require validation of a prerequisite regarding the vehicle's minimum speed and necessitates the acquisition, during the challenge, of data on the vehicle's lateral acceleration or steering angle, as well as brake pressure. The stopping condition relates to a time elapsed (or, respectively, a distance traveled), and achievement of the objective is assessed based on the number of turns completed using only regenerative braking during the challenge. A challenge based on measuring energy consumption over a given number of turns, for example, 20 turns. This challenge aims to assess the driver's ability to limit vehicle fuel consumption through a series of curves. It does not necessarily require the fulfillment of a prerequisite condition and requires the acquisition, during the challenge, of the steering wheel angle and the powertrain's fuel consumption for a gasoline engine and / or the energy consumption for an electric motor. The stopping condition relates to the number of turns completed, and achieving the objective is evaluated based on the energy consumed by the vehicle during the challenge. A challenge based on measuring the instantaneous energy consumed over a given number of turns, for example, 20 turns. This challenge aims to assess the driver's ability to maintain fuel consumption within a range corresponding to optimal vehicle consumption over a series of curves. It does not necessarily require the fulfillment of a prerequisite condition and requires the acquisition, during the challenge, of the steering wheel angle and the instantaneous fuel consumption of the powertrain for a gasoline engine and / or the instantaneous energy consumption for an electric motor. The stopping condition relates to the number of turns completed, and the achievement of the objective is evaluated based on the peaks in instantaneous energy consumed by the vehicle during the challenge. a challenge based on measuring the energy consumed over a given distance, for example 100km. This challenge aims to assess the capacity of the The driver is challenged to optimize the use of vehicle energy over a given distance. This does not necessarily require the fulfillment of a prerequisite, but it does require the acquisition, during the challenge, of the powertrain's fuel consumption for a gasoline engine and / or the energy consumption for an electric motor. The stopping condition relates to a distance traveled, and achievement of the objective is evaluated based on the energy consumed during the challenge. • A challenge based on a distance traveled for a given level of electric battery discharge and a given time, for example, no more than 85% battery discharge over a period of 2 hours. This challenge aims to assess the driver's ability to optimize the ratio between energy consumed and distance traveled. It does not necessarily require the fulfillment of a prerequisite condition and requires the acquisition, during the challenge, of the powertrain's fuel consumption for a gasoline engine and / or the energy consumption for an electric motor. The stopping condition relates to a duration and energy consumption, and achievement of the objective is evaluated based on the distance traveled during the challenge.

[0037] Of course, the list of possible challenges is not limited to the examples given above, the person skilled in the art being able to imagine a multitude of other challenges aimed at quantifying the driver's control of his vehicle on different aspects.

[0038] The method according to the invention finally includes a step 23 for unlocking vehicle functionalities. This step is conditional upon the prior achievement of predefined objectives for at least one of the challenges.

[0039] According to another embodiment of the invention, a points system can be used to unlock vehicle features. For this purpose, the driver can be awarded a certain number of points when a challenge objective is achieved. Thus, several points associated with several objectives can be awarded for the same challenge. The vehicle features are then unlocked according to the sum of the points awarded to the driver upon reaching certain point thresholds.

[0040] The vehicle features unlocked during stage 23 can be of several, non-exclusive types: - the unlocking of new challenges, so that the completion of certain challenges is conditional upon achieving specific performance levels on those challenges Previous challenges. Unlocking new challenges allows for a progressive assessment of the driver's mastery of the vehicle by presenting them with challenges of increasing complexity. It also encourages the driver to improve on previously completed challenges and to attempt challenges they might not have otherwise attempted, thus allowing for the evaluation and improvement of their skills across all desired skill areas. New challenges can be pre-loaded into the vehicle's memory, or downloaded from a remote server as they are unlocked; - unlocking new vehicle ambiences (cinematic dashboard animations, interior colors, etc.) or rewards (badges, trophies, etc.). This unlocking of ambiences or rewards has an incentive effect on the driver, pushing them to complete new challenges and improve on previously completed challenges, and consequently improve their vehicle control; - unlocking vehicle performance levels, such as different power levels delivered by the powertrain, particularly for an electric vehicle, unlocking a turbo button providing a temporary boost of energy to the powertrain, unlocking specific engine maps, and / or unlocking the ability to deactivate driving aids, such as ESP (Electronic Stability Program), ABS (Antiblockiersystem), AFU (Emergency Brake Assist) and / or ESC (Electronic Stability Control).This gradual unlocking of vehicle performance levels or the ability to deactivate driver assistance systems allows, particularly for a so-called "sporty" vehicle, for a good match between the vehicle's behavior and the driver's skill level. Thus, a novice driver may only have access to gentler engine maps without the option to deactivate driver assistance systems, resulting in a less aggressive and less risky driving experience than a more experienced driver, who will have access to maps and options allowing them to fully exploit the vehicle's performance.

[0041] The invention also relates to a vehicle such as the vehicle shown schematically in [Fig. 1], implementing an embodiment of the process This involves adapting a vehicle's features to the driver's skill level, as described previously. The process is then implemented by a vehicle computer, such as the ECU (Engine Control Unit). The vehicle may, in particular, be an electric vehicle.

[0042] Advantageously, the method can be implemented after prior verification of the identity of the vehicle's driver. This identity verification can be implemented by any means of authentication: visual recognition using a camera, biometrics by a fingerprint or iris reader, or voice recognition, or by a context menu in which the driver enters their identity or selects a profile from a list of registered drivers of the vehicle.
