    摘要: Powertrain propulsive torque monitoring and remedial action techniques for a cruise control mode of an electrified vehicle comprise obtaining a set of inputs indicative of a driver torque request and a state/grade of a road along which the vehicle is traveling, operating in a cruise control mode including determining a total torque request for an electrified powertrain, determining and commanding a distribution of the total torque request to the electrified powertrain, and determining the road state/grade based on at least some of the set of inputs, and monitoring the operating in the cruise control mode including determining an actual torque being generated by the electrified powertrain, determining upper and lower acceptable torque limits for the cruise control mode based on the road state/grade, and taking remedial action regarding the cruise control mode when the actual torque is outside of the upper and lower acceptable torque limits.

    摘要: A steer-by-wire control system that includes a road wheel actuation control system controlling road wheel angles to track a road wheel reference angle and a steering wheel control system producing a steering wheel angle to the road wheel actuation control system, steering feel for the vehicle driver and active steering wheel return. The steering wheel control system further including a steering wheel model matching controller that receives an input signal from the steering wheel control system and an input signal from the road wheel control system and generates a control output signal based on a model-matching control law, wherein the control output signal controls a reaction torque of the steering wheel control system to produce the steering feel for the driver and control the return rate of a steering wheel or a joystick.

    摘要: A system and method for vehicle dynamic control processes a compensated yaw rate signal measurement and a compensated lateral acceleration signal measurement (30, 32) to derive a signal measurement of road bank angle disturbance not compensated for in a compensated steering angle signal measurement and provides the derived signal to a controller (12). The compensated steering angle signal measurement is an input to the controller. Because a disturbance already compensated in the compensated steering angle signal measurement is transparent to the controller, the controller is able to adjust the control action of the vehicle dynamic control system based on the derived signal measurement of road bank angle disturbance not compensated for in a compensated steering angle signal measurement, thereby providing enhanced robustness of control.

    摘要: Control systems and methods for an electrified powertrain of an electrified vehicle include performing, by a main control system, a sequence of first processes based on an initial input including a set of signals indicative of at least one of a driver torque request and expected vehicle behavior and other intermediary inputs to generate a sequence of first outputs and performing, by a secondary monitoring system distinct from the main control system, a sequence of second processes based on the initial input and other intermediary inputs to generate a sequence of second outputs. The secondary monitoring system then attempts to rationalize each first output relative to its respective second output. Based on the rationalization, one of these outputs is used as an intermediary output in the sequence until a rationalized final output is obtained and used to generate control commands for torque actuators of the electrified powertrain.

    摘要: Systems and methods for controlling a park pawl system of a hybrid vehicle having a hybrid powertrain comprising an engine and a hybrid transmission comprising at least one electric propulsion motor, the systems and methods each utilizing a control system configured to detect, using a main control system portion, a desired park state based on at least an input via a transmission gear selector and an input via a brake pedal and detect, using a distinct monitoring system portion, whether the desired park state is valid based on at least the transmission gear selector and brake pedal inputs. When the desired park state is valid, the control system commands the park pawl system to the desired park state. When the desired park state is invalid, however, the control system commands an electric park brake of the vehicle to prevent movement at a driveline of the vehicle.
