Abstract
Abstract Pressure sensors situated on opposite sides of a land motor vehicle relative to the direction of travel enable a signal to be generated which is indicative of the presence and the direction of a gust of cross-wind striking the vehicle. Flaps, which are connected to the sensors and are normally closed flush with the body, are movable to project selectively from the outer surface of the motor vehicle, in the event of a gust, to induce in the vehicle a slewing moment in the direction opposite the direction of the gust.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A device for compensating for slewing induced in a land motor vehicle moving in one direction by gusts of wind transverse that direction, including: pressure sensor means arranged on opposite sides of the land motor vehicle relative to the said direction and able to generate a signal which is indicative of the presence of a gust and of the direction of the gust, and flap means movably mounted on opposite sides of the motor vehicle and able to induce in the moving land motor vehicle slewing movements in opposite directions, the flap means being operatively connected to the sensor means so that, in the event of a gust, a slewing movement is induced in the moving land motor vehicle in the opposite direction to the slewing induced by the gust.
Claim 2
Independent Claim
130 words
A device for compensating for slewing induced in a land motor vehicle moving in one direction by gusts of wind transverse that direction, including: pressure sensor means arranged on opposite sides of the land motor vehicle relative to the said direction and able to generate a signal which is indicative of the presence of a gust and of the direction of the gust, and flap means movably mounted on opposite sides of the motor vehicle and able to induce in the moving land motor vehicle slewing movements in opposite directions, the flap means being operatively connected to the sensor means so that, in the event of a gust, a slewing movement is induced in the moving land motor vehicle in the opposite direction to the slewing induced by the gust.
Claim 3
Dependent Claim
21 words
A device according to claim 1, wherein the pressure sensor means are situated adjacent the front end of the motor vehicle.
Claim 4
Dependent Claim
27 words
A device according to claim 1, wherein the flap means include flaps which are able to project selectively from the outer surface of the motor vehicle sides.
Claim 5
Dependent Claim
66 words
A device according to claim 1, wherein the flap means include at least two sets of flaps, one set for each of the slewing directions, and each set includes: at least one flap situated at the front end of the motor vehicle on one side thereof, and at least one other flap situated at the rear end of the motor vehicle on the other side thereof.
Claim 6
Dependent Claim
23 words
A device according to claim 4, wherein each set includes a pair of flaps situated at the front end of the motor vehicle.
Claim 7
Dependent Claim
49 words
A device according to claim 1, wherein a threshold circuit is interposed between the sensor means and the flap means and is able to prevent activation of the flap means when the modulus of the amplitude of the signal generated by the sensor means is less than the threshold.
