Autonomous driving techniques comprise determining a Form of Way (FOW) classification of a road along which a vehicle is traveling and when the determined FOW classification is FOW 1 or FOW 9, permitting level 2 autonomous driving of the vehicle. When the determined FOW classification is FOW 2, the techniques determine whether a set of operating conditions relating to autonomous driving satisfies a set of criteria that assesses a set of upcoming stubs along a future section of the road along which the vehicle will potentially travel are satisfied and when the set of criteria are satisfied, permitting level 2 autonomous driving of the vehicle and when the set of criteria are not initially satisfied or are subsequently no longer satisfied, not permitting or at least temporarily interrupting level 2 autonomous driving of the vehicle.

Systems and methods of level 2 autonomous vehicle driving on multiply digitized roads

A method of identifying a radar requiring alignment and of adjusting the alignment of the radar fixed to a mounting assembly. The identification method includes the steps of determining a misalignment threshold, determining the misalignment angle of the radar, and creating an alignment notice if the misalignment angle exceeds the threshold. The mounting assembly for the adjustment method includes a housing and an adjustment mechanism coupled to the housing. The method includes the steps of determining a radar misalignment angle, consulting a mapping table having adjustment mechanism manipulations associated with each of a plurality of radar misalignment angles to identify an appropriate adjustment mechanism manipulation for the misalignment angle, and performing the adjustment mechanism manipulation identified in the mapping table for the determined radar misalignment angle.
