Problems solved by technology

[0007] An accompanying problem is to find an actuator suitable for obtaining a good compromise between the active automatic action of changing the vehicle's trajectory to prevent lane departure and the driver's perception that its action is neither known nor predictable

Embodiment Construction

[0038] like figure 1 As can be seen in the figure, the vehicle 1 comprises a chassis 2, two steered front wheels 3 and 4 and two steered rear wheels 5 and 6, which are linked to the chassis 2 via a not-shown suspension mechanism.

[0039] The vehicle 1 is supplemented with a steering system 7 comprising a rack 8 arranged between the front wheels 3 and 4, adapted to make the front wheels 3 and 4 available to the driver of the vehicle according to a never shown The steering wheel receives commands mechanically or electronically through the rack 8 to orient a rack actuator 9 .

[0040] The steering angle assist control system 10 comprises a control unit 11, a sensor 12 (for example positioned on the actuator 9) for sensing the steering angle position of the front wheels 3 and 4, sensing the rotational speed of these front wheels such that there is A sensor 13, possibly determining the velocity V of the wheel, senses the yaw velocity of the vehicle (ie the rotational speed of t...

Abstract

In view of controlling the course of a vehicle (1), the device comprises at least one input (43, 44) for receiving at least one quantity representative of one or more differences (PsiL, yL) between a reference course (30) and an actual course of the vehicle. Remarkably, the device (40) comprises at least one output (46) for producing, in real time, at least one steering set point (deltar*) applicable to at least one rear wheel of the vehicle (1) in such a way as to maintain and / or bring said vehicle onto the reference course of same.

Description

technical field [0001] The invention relates to a device for generating control over vehicle trajectories in real time. The invention also relates to a vehicle equipped with such a device. Background technique [0002] Among other things, the present invention addresses the need for active accident prevention. Today, accidents due to unintentional lane departures still account for a significant proportion of accidents. To enhance occupant safety, motor vehicle designers have improved passive prevention by producing vehicles that are more impact resistant and absorb a significant proportion of the energy generated by impacts. Proactive prevention involves producing a vehicle that enables it to estimate its dynamics and recognize its environment in order to have a risk measure that reflects its situation. Measures can then be taken automatically or together with the driver to keep the vehicle in its lane in the event of lack of alertness, sleep, illness or unprepared extern...
