    Abstract: Presented herein are adaptive power assist systems for manually-powered vehicles, methods for operating/constructing such systems, and motor-assisted, operator-powered vehicles with input torque filtering for adaptive power assist operations. A method for regulating a power assist system includes a vehicle controller receiving torque sensor data indicative of user-generated torque input. The vehicle controller then determines: if the torque input is less than a commanded motor torque generated by a tractive motor; and, if a calibrated motor decay time of the tractive motor is less than a scaled cadence time of the user's cadence speed. Responsive to both determinations being positive, the vehicle controller calculates a torque decay factor based on the current cadence speed, and modifies the commanded motor torque based on this calculated torque decay factor. The vehicle controller then transmits command signals to the tractive motor to output a modulated motor torque according to the modified commanded motor torque.

    Abstract: A road load module is configured to determine a road load torque to maintain zero vehicle acceleration. An initialization module is configured to determine an initial torque based on the road load torque. A closed loop (CL) module is configured to: when a CL state transitions from an inactive state to an active state, set a CL torque to the initial torque; and when the CL state is in the active state after transitioning to the active state, adjust the CL torque based on a difference between a target vehicle speed and a vehicle speed. A motor torque module is configured to determine a motor torque command based on the CL torque and a motor torque request determined based on an accelerator pedal position. A switching control module is configured to, based on the motor torque command, control switching of an inverter and apply power to an electric motor.

    Abstract: Methods and apparatus are provided for controlling an autonomous vehicle. The control device includes an interface that establishes a connection to an autonomous vehicle, a processor that processes inputs and generates control commands to control at least one function of the autonomous vehicle, and an input arrangement with at least one control element that is assigned to a function of the autonomous vehicle. The control device transitions a controller of the autonomous vehicle to operate in at least one of a first remote operation mode and a second remote operation mode in which the autonomous vehicle is controlled by the control device, when the control device is connected to the autonomous vehicle via the interface. At least one function of a scope of functions of the autonomous vehicle is restricted in the first remote operation mode and the second remote operation mode.

    Abstract: A method of operating a vehicle includes a vehicle controller receiving a driver acceleration/deceleration command for the vehicle's powertrain and determining a torque request corresponding to the driver's acceleration command. The controller shapes the torque request and determines compensated and uncompensated accelerations from the shaped torque request. The compensated acceleration is based on an estimated road grade and an estimated vehicle mass, whereas the uncompensated acceleration is based on a zero road grade and a nominal vehicle mass. A final speed horizon profile is calculated as: a speed-control speed profile based on the uncompensated acceleration if the vehicle's speed is below a preset low vehicle speed; or a torque-control speed profile based on a blend of the compensated and uncompensated accelerations if the vehicle speed exceeds the preset low vehicle speed. The controller commands the powertrain to output a requested axle torque based on the final speed horizon profile.
