Abstract: 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.

Abstract: Methods and apparatus to control a torque threshold for hands on/off detection are disclosed. An example apparatus includes memory including instructions, and one or more processors to execute the instructions to cause the one or more processors to at least compare a velocity of a rack to at least one of a first velocity threshold or a second velocity threshold, adjust a first torque threshold in response to the velocity of the rack satisfying the first velocity threshold, adjust a second torque threshold in response to the velocity of the rack satisfying the second velocity threshold, compare a torque between the rack and a steering shaft to the first torque threshold and the second torque threshold, and detect a hands off condition in response to the torque between the rack and the steering shaft not satisfying the first torque threshold or the second torque threshold.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to improve electronic power assisted steering in a vehicle. An example apparatus includes memory and a processor to execute instructions to determine a steering column torque associated with a steering column of an electronic power assisted steering (EPAS) system in a vehicle, determine a steering column torque derivative based on a derivative of the steering column torque, determine a compliance compensation torque based on the steering column torque and the steering column torque derivative, and adjust a steering response of the steering column based on the compliance compensation torque.

Abstract: A system and a method are described. The method includes: receiving sensed input from a vehicle sensor suite; using the input, providing a first output; determining that a vehicle-lane confidence level is less than a threshold; and then instead, providing a second output, wherein the first and second outputs comprise lane-correction data, wherein the second output is determined using an estimation filter.

Abstract: A current value of a state-of-motion from a second controller can be received by a first controller. The first controller determines a subset of a target value of the state-of-motion to be achieved by a subsystem and transmits a command to a third controller in communication with the subsystem to achieve the subset of the target value of the state-of-motion. The third controller commands the subsystem to approach the subset of the target value of the state-of-motion.

Abstract: An autonomous steering system for a vehicle includes a park assist steering module configured to generate a first steering angle command across a communication network of the vehicle. A backup assist steering module is also configured to generate a second steering angle command across the communication network of the vehicle. A steering angle controller is configured to receive the first and second steering angle commands and generate a third steering angle command for controlling a steered wheel of the vehicle based on acceptable steering column torque conditions for the respective steering module.

Abstract: A system for correcting steering wheel angle errors of a motor vehicle of the present disclosure may include a steering wheel angle sensor, an actuator angle sensor, and at least one of a wheel speed sensor and a lateral acceleration sensor. The system may further include a controller configured to receive signals from the steering wheel angle sensor, actuator angle sensor, and at least one of the wheel speed sensor and lateral acceleration sensor. The controller may be configured to calculate a correction angle based on the signals, and adjust a steering wheel angle of a steering wheel, as observed by a driver of the motor vehicle, based on the correction angle.
