  • Patent number: 7012509
    Abstract: The invention concerns a device for detecting a running surface for vehicle, comprising a plurality of sensors designed to be oriented towards the running surface to determine modifications thereof, means for processing the data concerning information picked up by the sensors, wherein at least part of the sensors are relatively arranged such that at least the transverse distances separating two adjacent points of aim on the ground of the sensors increase towards a longitudinal axis and along a direction substantially perpendicular to this axis. The invention also concerns a vehicle using this device.
    Type: Grant

  • Patent number: 6925859
    Abstract: A device for detecting a running surface for a vehicle, comprising a plurality of sensors (c1 to c8) designed to be oriented towards the running surface to detect modifications thereof, data processing means for processing data derived from the sensors, wherein the sensors are relatively arranged so as to associate at least part of the points of aim on the ground (v1 to v8) in pairs (p1 to p4), the two points of aim on ground the ground being spaced apart by a first specific distance, and the transverse distances separating two adjacent pairs (p1 to p4) of points of aim on the ground increase towards a longitudinal axis along a direction substantially perpendicular to said axis.
