摘要： A system is disclosed that includes a computer and memory, the memory including instructions to acquire images, including a first image and a second image of an object attached to a platform that is moving and determine a first real world location of a fiducial marker and a second location of the fiducial marker. A center of rotation for the object can be determined by tracking the first and second real world locations of the fiducial marker and an angle of an axis the object with respect to an axis of the platform can be determined based on the center of rotation, the tracked locations of the fiducial marker, and calibration data.

摘要： A computer includes a processor and a memory, the memory storing instructions executable by the processor to receive sensor data indicating an obstacle, formulate a control barrier function for a vehicle based on the sensor data, determine a control input based on the control barrier function, and actuate a component of the vehicle according to the control input. The control barrier function is defined with respect to a reference point that is spaced from a centroid of the vehicle.

摘要： A lateral virtual boundary for a host vehicle is identified based on a lateral distance between the host vehicle and a target vehicle, a longitudinal distance between the host vehicle and the target vehicle, and a speed of the target vehicle relative to the host vehicle. A forward virtual boundary for the host vehicle is identified based on the longitudinal distance between the host vehicle and the target vehicle. A lateral constraint value of the lateral virtual boundary and a forward constraint value of the forward virtual boundary are determined. A longitudinal acceleration and a steering angle are determined based on the lateral and forward virtual boundaries and the lateral and forward constraint values. One or both of a steering component or a brake are actuated based on the longitudinal acceleration and the steering angle.

摘要： The present disclosure generally relates to an obstacle avoidance system with active suspensions. The obstacle avoidance system uses one or more active suspensions to lift or jump one or more corresponding wheels over an obstacle in the vehicle's path to avoid contact with the obstacle when the vehicle cannot practically drive over, steer around, or stop before hitting the obstacle.

摘要： A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated fiction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided. Measured torque values are used during a torque phase of the upshift to correct an estimated oncoming friction element target torque so that transient torque disturbances at an oncoming clutch are avoided and torque transients at the output shaft are reduced.
