    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.

    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 system and a method for dynamically estimating a lateral velocity of a motor vehicle for input to a controller employed to control dynamics of the motor vehicle includes sensors for measuring predetermined vehicle operating state. The system also includes sensors for dynamically measuring steering angle, vehicle speed, yaw rate and lateral acceleration. These signals are combined and numerically integrated in accordance with assymptotic observer theory to obtain a reliable estimate of the lateral vehicle velocity.

    摘要: A system and a method for dynamically determining a lateral acceleration of a motor vehicle for input to a controller employed to control dynamics of the motor vehicle includes sensors for measuring predetermined vehicle operating state. The system also includes a device for predicting a value for the lateral acceleration, which can then be used to determine a correction factor for the measured lateral acceleration signal. This correction factor is proportional to the erroneous component of the lateral acceleration signal. Together, measured operating state and the correction signal are used to obtain a compensated operating state signal. This is particularly useful for reducing the errors attributable to sensor drift and DC offset in measured signals.
