- CCD type for "Load Coupling Sensors”
- the analysis of the images provided by this camera also makes it possible to establish the level of fluidity of the road traffic.
- the module 20 also comprises a plurality of sensors measuring certain internal driving parameters such as speed the vehicle and the steering angle of the steering wheel.
- the data collected by the two driver monitoring modules 10 and driving context assessment 20 are routed in real time to the control unit 30 to which these two modules are connected.
- the control unit 30, preferably constituted by the intelligent service housing (BSI) of the vehicle, comprises a computer 31 and a storage module 32 comprising non-volatile memory type EEPROM or FLASH and RAM .
- the non-volatile memory stores a process for assisting activation of the motor vehicle driving assistance modes whose flowchart is shown in FIG. 2 and which is implemented cyclically according to a predetermined period of time inclusive of preferably between 100 ms and 1000 ms.
- non-volatile memory can be updated by means of communication or reading means of a data medium.

- This actuation module 40 comprises a plurality of actuators able to control certain vehicle components such as steering, acceleration, braking and gearbox to ensure the implementation of the various modes of assistance to driving. with which the vehicle is equipped, namely in this case:
- a second mode of assistance for adaptive speed control ensuring only the control of the longitudinal movement of the vehicle and wherein the control of the lateral movement remains the responsibility of the driver via the steering wheel;
- a third mode of assistance for example for driving on motorway, ensuring both lateral and longitudinal control of the vehicle in situations of fluid traffic (speed close to the statutory limit) on separated highways and in which the driver is required to keep his eyes fixed on the road as the guidance can only be maintained for a short period of 1 to 3 seconds in case of loss of information (disengagement with rapid transition).
- a fourth mode of assistance for example for driving in a traffic jam, ensuring both control of the lateral and longitudinal displacement of the vehicle in situations of heavy traffic or traffic jams (speed below a predetermined threshold value, for example between 50 and 70 km / h) and on roads with separate carriageways and in which driver is not required to keep his eyes fixed on the road and can go about other occupations because the guidance can be maintained over a period of a few seconds (for example between 5 and 15 s) in case of loss of information (disengagement with normal transition).
- a predetermined threshold value for example between 50 and 70 km / h
- the information and warning module 50 comprises a first information screen 51 integrated in the central console of the dashboard of the vehicle (the latter being preferably constituted by the display screen of the information device. entertainment) and able to broadcast visual messages indicating the driving position or positions proposed to the driver according to the available modes of assistance. For better legibility, this information is preferably displayed in the form of luminous pictograms such as those shown in FIG.
- the module 50 also preferably includes a second warning screen 52 integrated in the instrument cluster of the vehicle and intended to display visual messages.
