Definitions
- the subject of the invention is that of assistance in driving a vehicle. More particularly, the invention relates to an assistance function making it possible to anticipate collisions between the vehicle and objects present in the environment of the vehicle in question.
- ABS Anti-Braking System
- the ultimate goal of these assistance functions is to reduce road safety.
- ACC Adaptive Cruise Contrai
- ACC Adaptive Cruise Contrai
- the ACC system can only be used on highways when driving situations are simple.
- an assistance function to avoid collisions, which operates in a complex environment, particularly in an urban environment. Indeed, in the latter case, the vehicle may collide with objects of various kinds, sometimes vulnerable and unpredictable behavior. In particular, an object may be temporarily obscured by another object in the scene. This is for example the case of a masked pedestrian behind a parked vehicle.
- the object of the invention is to provide an assistance function making it possible to anticipate collisions that can be implemented in a complex environment.
- the invention also aims to meet the aforementioned drawbacks and in particular to take into account the occultations of objects.
- the invention In order to be effectively embarked on board a vehicle, the invention must make it possible to take into account as accurately as possible the objects of the scene, limiting as much as possible the errors on the presence of an object in a given scene location. .
- the invention must be implemented almost in real time to take into account rapid changes in the scene.
- FIG. 1 schematically shows a vehicle carrying the driver assistance device according to the invention.
- a - General Description of an Embodiment The driving assistance method according to the invention is implemented on a vehicle 1 shown schematically in FIG.
- the vehicle 1 comprises four wheels 2a-d.
- the front wheels 2a and 2b are for example driven by a heat engine.
- Each of the wheels 2a-d is equipped with braking means 3a-d.
- the front wheels 2a and 2b are equipped with brakes hydraulic, while the rear wheels 2c and 2d are equipped with electromechanical brakes 3c and 3d.
- the vehicle 1 comprises a plurality of sensors. Speed sensors 4a-d are arranged on each of the wheels 2a-2d. Each speed sensor makes it possible to measure the speed of rotation of the wheel that it equips.
- the vehicle 1 is also equipped with an acceleration sensor 5.
- the various sensors deliver signals that are routed via a communication network (for example of the CANBus type) to a central computing unit 6.
- computation 6 comprises a processor capable of executing the instructions of a computer program.
- the calculation unit 6 also comprises storage means for permanently storing said instructions and predefined parameters or ephemeral results of calculations performed by said processor.
- the computing unit also has a clock for timing and synchronizing its operation.
- the computing unit 6 has input / output interfaces allowing the input reception of the signals coming from the different sensors and the output of control signals towards actuators.
- the calculation unit 6 calculates from the different signals emitted by the speed sensors 4a-d, the longitudinal speed of the vehicle 1.
- the calculation unit 6 may comprise brake management functions, for example of the ABS type ("Anti-lock braking System" for "anti-locking wheels”). As a function of the speed, the calculation unit 6 determines the sliding of each of the wheels. When the slippage of one of the wheels is greater than a predetermined threshold, the calculation unit 6 emits a brake actuation signal so as to reduce slippage on the wheel in question. This additional braking is not managed at all by the driver of the vehicle for which this operation is completely transparent.
- brake management functions for example of the ABS type ("Anti-lock braking System" for "anti-locking wheels”
- the vehicle 1 is equipped with at least one sensor for detecting the presence of an object.
- the sensor 10 shown is a laser range finder. It can detect objects present in a "field of view" or corresponding detection zone, in a horizontal plane, to a cone of total opening angle ⁇ o of about 90 ° to a depth p 0 of about 20 m in front of the vehicle.
- the sensor on board the vehicle could be a detector of the laser or sonar type, or even a CCD camera.
- CCD camera it is necessary to understand not only the detector, but also the pre-processing electronics of the image which produces a signal comprising exploitable information.
- the pre-processing electronics is able to generate a frame around a moving object by grouping all the points of the moving image of the same speed.
- the senor has been represented in the front position on the vehicle 1 so that the detection zone is in front of it.
- the sensor can be arranged so that it allows assistance during a reverse or closing of the bus doors, the detection zone then being behind the vehicle or on the side of it.
- the presence detection sensors of objects can be arranged in a fixed manner in the landscape.
- a sensor 10 ' which can be attached to an element of the road infrastructure such as a bus shelter, a guardrail, a sign or the equivalent.
- the sensor 10 ' is equipped with transmission means, which, either directly or through relay means, make it possible to transmit a detection signal to the vehicle 1.
- the latter equipped with reception means schematized by the antenna 8, is suitable to put the detected object back into its own repository.
- the vehicle 1 comprises positioning means of the GPS type possibly with local positioning beacons.
- the laser rangefinder comprises a source 10a emitting a directional beam. In a period of time marked by an integer k and having a sampling period of the order of 10 ms, the beam sweeps the opening cone ⁇ o. Part of the energy of the emitted beam is reflected by an object towards the vehicle 1.
- a receiver 10b detects the reflected beam.
- the data acquisition electronics 10c of the sensor 10 determines the distance p and the angular position ⁇ of the detected object.
- a laser range finder does not provide a measure of speed. This is why the acquisition electronics may optionally perform a preprocessing step for estimating a value of the speed of the detected object, for example based on a nearest neighbor algorithm between two successive measurements of the depth and angular position of the detected object.
- the sensor 10 emits a signal corresponding to a measurement in position and, possibly, in speed of the detected object at time k.
- the measurements are made relative to the reference frame of the vehicle 1.
- the positioning data of an object is transmitted to the vehicle 1 which, in a simple manner, can determine the position of the object detected by change of reference, taking into account its position, its speed and its acceleration with respect to the static sensor, dynamic values which are obtained as indicated above by means of a system Positioning GPS type.
- the measurement made by the sensor 10 is transmitted, via communication lines, at the input of the calculation unit 6.
- the spatial domain ⁇ in which it is desired to determine the presence of an object corresponds to a rectangular zone in front of the vehicle 1. This two-dimensional zone is marked by Cartesian coordinates: Xi in the longitudinal direction 1 and X2 in the direction cross.
- this spatial domain ⁇ is digitized. It is cut into cells having a predetermined regular pitch ⁇ X1 in the direction Xi and ⁇ X 2 in the direction X 2 . It is therefore the regular and static discretization of the vehicle environment in the form of a set of N X-cells (Xi, X 2 ).
- the two-dimensional grid currently used has of the order of 100,000 cells. In the embodiment of the figurel, it typically extends 20 m along X and 20 m X 2 . As shown in the figure
- the spatial domain ⁇ is not superimposed exactly on the detection zone covered by the sensor 10.
- the algorithm according to the invention is coded so as to be fully parallelizable. Its implementation can be done by means of an electronic card comprising N processors operating in parallel. Each processor calculates the probability of occupation of the cell of the grid that it represents.
- the algorithm according to the invention is subdivided schematically into several modules: the first module consists of modeling the response of the sensor.
- This "sensor model” is based on a probability distribution P (Z k
- E x k X) indicates the probability of observation Z k knowing the state E k x of cell X at time k.
- capital letters indicate a variable that can take a set of possible values indicated in lowercase.
- the second module is a prediction module. It makes it possible to predict the state E k x of the cell X at the instant k taking into account the state of the gate at time k-1.
- the third module is an estimation module making it possible to calculate the occupation probability E k x of the cell X at the instant k taking into account the observations Z k at the instant k, and the result of the prediction step obtained at the output of the second module.
- a fourth module finally allows to associate the cells of the grid whose probability of occupation is high a magnitude indicating a collision risk and to emit a suitable signal.
- the information recovered by the sensor is limited in precision. Many factors affect the accuracy of the measurement: temperature, lighting, color of the object, etc. To make the most of the measurements, it is important to take into account the sound of the magnitude observed.
- the sensor response is described by a probabilistic model specified as a Bayesian program.
- the relevant variables of the problem are the Z observation; the X cell; the variable E x meaning that an object exists in the cell X; and, the variable D x meaning that an object has been detected in the cell X.
- an object occupies the X cell, but it is not detected by the sensor. This is for example the case when the X cell is outside the detection zone of the sensor, the X cell is masked by another object, or when the sensor is faulty;
- conditional probability P (Z, X, E x , D x ), expressing the conjunction of the various variables selected, is advantageously decomposed into the form:
- X) represent a priori knowledge about the environment of the vehicle. At first, in order not to privilege any particular situation, these distributions are chosen uniform. But, as will be explained below, P (E X
- PD (X) and PFA (X) can be estimated from a modeling of the physical characteristics of sensors and detected objects. They can also be “learned” experimentally in the particular conditions of use of the sensor during a first calibration step.
- the occupancy grid is a spatial grid. Consequently, for each value of the speed (two dimensions) one has to store a two-dimensional occupation grid. As a result, it is necessary to store a large amount of data in order to have an accurate representation of the environment, ie to monitor large areas of the environment with a fine discretization step to distinguish the objects. Besides the problem of the memory size required, the speed of data processing is a crucial parameter in a real-time application.
- a data structure representing the occupancy grid but having a reduced memory size is used.
- the update of the probability of occupation of cell x corresponds to:
- This update chain is used with the initial distribution which is chosen uniform since no information about the environment is a priori available.
- the logarithm of the variable q k can be taken into account so as to transform the product into a sum in the preceding relation:
- the advantage of passing through the log ( ⁇ ) variable is that it is easy to compress the equivalent occupation grid by performing a wavelet transform, for example by means of Haar wavelets, and then removing the low amplitude coefficients.
- wavelet transform is widely described in the literature and has been the subject of numerous publications both scientific and popularization. It will be noted that, advantageously, the space of the signals transformed into wavelets is a vector space, which is as such stable by the addition and multiplication operations by a scalar. Moreover, the wavelet transformation is a linear operation with respect to the number of data, which guarantees a fast execution of the compression algorithm.
- Y (Z 1, Z, XE x ) P (X) P ( ⁇ IX) ⁇ P ( ⁇ IE x X).
- E x , X) is the model of the i th sensor as described in detail above.
- the modules for predicting and estimating a probability of occupation at time k implement the notion of Bayesian filter applied to the occupation grids.
- a Bayesian filter is used to predict the temporal evolution of a system. The purpose here is to give the occupancy grid a certain robustness allowing it to take into account a sensor failure or the transient occultation of an object in the risk assessment.
- a prediction step whose goal is to estimate a priori the state of occupation of the cell.
- An estimation step whose purpose is to calculate the occupation probability taking into account the prior estimate and the instantaneous observation.
- the variables considered are:
- P (E x , X 'z) is the estimated occupancy probability of cell X' at time k-1; where P (E x k is the transition probability of any intermediate state (E x : 1 , X ') of the system at time k-1 to the considered state (E x , X), ie corresponds to the dynamic model of the system; and where we sum on the set of possible intermediate states (E *: 1 , X ').
- the two-dimensional Cartesian space is continuously discretized, then, in a second step, the number of possible speed planes is restricted.
- the allowed movements are those that exactly pass a cell to another cell in a number n times the sampling interval ⁇ t.
- a velocity plane is a two-dimensional spatial grid that is associated with a triplet (p, q, n) defining a velocity. There is certainly a discretized speed space, but it is not continuous.
- the factor 1 / n makes it possible to consider the velocity plane (p, q, n) only at a frequency 1 / n. for a low-speed plane, the integral will only be calculated at a low frequency, but a plane in which a high-speed object is located will be observed at a higher frequency so as to take into consideration the rapid evolution of the behavior of this object.
- a spatial region (2D) around a central cell X 0 type is delimited; a maximum number n max of time step is defined.
- the set of cells in this region are those that can reach the central cell X 0 in 1, 2, ... n max no time.
- V f The set of possible velocities V f of the form (p / n ( ⁇ xi / ⁇ t), q / n ( ⁇ x 2 / ⁇ t)) that allow one of the cells of this region to propagate towards the central cell X 0 in at most n max no time is determined;
- each element (p, q, i) belonging to one of the V fi is associated a two-dimensional spatial grid G ⁇ P , q) .
- the antecedent of a cell (I, m) of this grid is the cell (lp, mq).
- a counter k giving the index of the time step, incremented by one unit at each iteration evolves between the null value and the value corresponding to the least common multiple of the numbers 2 and n max . (Indeed, we must consider the smallest common multiple since it is a set of loops nested in each other). At the beginning of the process, it is instantiated at the null value; The probability of occupying the cell.
- Y (XE x MZ) F (X) Y [E x
- This relation is a static relation, which is made dynamic by introducing the estimation / prediction loop described previously on a set of variables between an initial moment 0 and a present instant k.
- the association variable M k indexed by time, makes it possible to associate with the estimation of the state, one of the O k observations made at time k.
