Automated vehicle protected and aerodynamically located sensors
View Patent ↗A sensor mounting arrangement suitable for an autonomous or automated vehicle having an aerodynamic generally rounded or curved front perimeter surface symmetrically arranged relative to a longitudinal axis of the vehicle. The sensor is mounted so as to be tipped toward a more optimal sensing direction, bringing a leading portion outboard of, and a trailing portion inboard of, the ideal front perimeter surface, but putting the sensor in a more optimal sensing orientation. A transparent cover protects the sensor and blends aerodynamically into the front perimeter body surface.
1. In a vehicle having a generally curved front perimeter body surface that is generally symmetrically defined about a longitudinal body axis, and a side mounted sensor having a generally planar, outwardly facing front surface defined between leading and trailing corner edges, a sensor mounting arrangement comprising,
said leading sensor edge being mounted to said vehicle with said leading corner edge outboard of, and said trailing corner edge inboard of, said perimeter surface, and a substantially transparent cover mounted to said vehicle so as to cover said sensor in a weather tight fashion and so as to blend aerodynamically into said front perimeter surface.
2. A mounting arrangement according to claim 1 , in which said sensor is a lidar unit and said cover is transparent to light.
3. A mounting arrangement according to claim 1 , in which said sensor cover has a relatively short leg covering said sensor leading corner edge and a relatively longer leg covering said sensor front surface.
4. A mounting arrangement according to claim 1 in which said cover is in turn mounted in a trim piece fixed to said vehicle.
