- FIG. 2 schematically represents the structure and the operation of a device for indicating the change of direction according to the invention
- FIG. 3 shows a curve illustrating the variation according to the invention of a turning threshold of the vehicle wheels as a function of the speed of the vehicle.
- the vehicle 1 illustrated in FIG. 1 comprises means 2, 12 intended to indicate a change of direction by the generation of light signals 9.
- the means 2, 12 for indicating a change of direction may consist of flashing lamps.
- These flashing lights 2, 12 can be located at the front, at the rear and possibly in the central part of the vehicle 1 in the form of side repeaters.
- the device for indicating a change of direction comprises means 5, 6, 7, 8, 10 for acquiring data relating to the operating conditions of the vehicle. These data acquisition means are connected to means 4, 3 for controlling the supply voltage of the light signaling means 2, 12.
- the electronic architecture of the lighting device can be a multiplexed architecture, for example of the VAN or CAN type.
- the means 3, 4 for controlling the lighting of the flashing lamps 2, 12 comprise a control computer 4, for example the Intelligent Service Unit (BSI) of the vehicle.
- BSI Intelligent Service Unit
- the means 5, 6, 7, 8, 1 0 for acquiring data relating to the operating conditions of the vehicle are connected to the control computer 4.

- the data acquisition means also comprise means 6 for detecting the presence or not of another adjacent vehicle located upstream and / or behind and / or laterally with respect to the vehicle 1.
- the computer 4 controls the actuator 3 to automatically turn on the indicators 2 , 12 lights located on the side of the vehicle corresponding to the steering of the wheels.
- the means 6 for detecting the presence of an adjacent vehicle may consist, for example, of a radar system such as that of an anti-collision device. Conventionally, these anti-collision systems are arranged in the front and rear parts of the vehicle to detect the presence and the distance of the vehicles, located upstream and / or downstream and possibly laterally, by using the phenomenon of reflection of the radar waves.
- the means for detecting the presence of an adjacent vehicle may consist of any other equivalent device such as, for example, a system 7 for receiving information representative of the state of road traffic emitted by means of broadcast such as a satellite. That is to say that the control computer 4 can be informed of the possible presence of an adjacent vehicle by means of satellite information such as a "GPS".

- the device according to the invention may include means 8 for detecting the position of the vehicle 1 relative to the marking lines on the ground separating the traffic lanes.
- These detection means 8 are in particular capable of detecting the possible crossing of these lines by the vehicle.
- these detection means 8 can consist of a system for emitting infrared waves and for receiving waves reflected by the ground, such as that described in document EP 860001. In this way, when the crossing, even partial, of a marking line on the ground is detected, or when the vehicle comes too close to it and the steering angle of the wheels is greater than the threshold E1, the computer 4 controls the automatic switching on of the corresponding signaling means 2, 12. As a variant, the infrared detection means 8 can also ensure the detection of the presence of an adjacent vehicle.
