Abstract: A method includes obtaining information about a lead vehicle. The lead vehicle is traveling directly ahead of the host vehicle and the information includes velocity of the lead vehicle and a gap g between the host vehicle and the lead vehicle. Based on detecting a change in the velocity of the lead vehicle in the information, a corresponding desired acceleration is computed for the host vehicle using perceived acceleration of the lead vehicle to maintain the gap g within a specified range of gap values. The perceived acceleration of the lead vehicle is based on the change in the velocity indicated by the information. Based on a check of parameters involved in the computing the corresponding desired acceleration, a modified desired acceleration is computed for the host vehicle using a lag for the lead vehicle that results in an intended acceleration of the lead vehicle differing from the perceived acceleration.

Abstract: A system of controlling operation of a vehicle includes one or more sensors operatively connected to the vehicle. The sensors are configured to obtain respective data of a scene and include a radar unit. A command unit is adapted to receive the respective data and includes a processor and tangible, non-transitory memory on which instructions are recorded. The command unit is configured to determine an orientation angle of a pedestrian in the scene, a Doppler frequency of the pedestrian and a distance of the pedestrian from a border of a road, based in part on the respective data. The orientation angle is based on a heading of the pedestrian relative to a direction of a road. The command unit is configured to designate a status of the pedestrian as either crossing or not crossing based on the distance, the orientation angle and the Doppler frequency of the pedestrian.
Abstract: A system for evaluating a rigidity of an angle bracket includes a test system having a first test fixture and a second test fixture. The system includes an angle bracket coupon including a first wall, a second wall coupled to the first wall at a bend to define an angle between the first wall and the second wall, and at least one three dimensional feature defined at the bend that extends between the first wall and the second wall. The angle bracket coupon is to be coupled to at least one of the first test fixture and the second test fixture to evaluate the rigidity of the angle bracket.
