Abstract: A system and method for monitoring a vehicle pedal are disclosed. According to the present disclosure, the method comprises determining whether a stimulus has been detected at the vehicle pedal. When the stimulus has been detected, the method comprises receiving sensor data from a sensor system, the sensor data being indicative of a shape of the stimulus, and determining whether the shape of the stimulus corresponds to an unintended object based on the sensor data. When the shape of the stimulus corresponds to an unintended stimulus, the method comprises performing an unintended stimulus operation.

Abstract: Methods and systems of processing sensor signals to determine motion of a motor shaft are disclosed. This disclosure relates to the processing of sequences of pulses from a sensor for computing the motion of an electric motor output shaft. Furthermore, this disclosure relates to the processing of two sequences of pulses from sensor outputs, which may be separated by only a few electrical degrees, to compute the motion of an electrical motor output shaft while using a limited bandwidth controller. Motor shaft direction, displacement, speed, phase, and phase offset may be determined from processing the sensor signals.

Abstract: A method of operating a park lock mechanism in a vehicle includes determining a force acting on a vehicle park lock mechanism when the vehicle is in park, and providing an offsetting force to counteract the force on the park lock mechanism before the vehicle is shifted out of park. In doing so, harshness and noise that may be associated with shifting a vehicle out of park, especially when the vehicle is parked on an incline, can be reduced or eliminated.

Abstract: An indicator, system and method of indicating electric drive usability in a hybrid electric vehicle. A tachometer is used that includes a display having an all-electric drive portion and a hybrid drive portion. The all-electric drive portion and the hybrid drive portion share a first boundary which indicates a minimum electric drive usability and a beginning of hybrid drive operation of the vehicle. The indicated level of electric drive usability is derived from at least one of a percent battery discharge, a percent maximum torque provided by the electric drive, and a percent electric drive to hybrid drive operating cost for the hybrid electric vehicle.

Abstract: The technology described herein provides a powertrain system with a route-learning feature. Particularly, learned information is used to optimize powertrain operation along any learned route. The learned information comprises, generally, feedback from the vehicle's acceleration and brake sensors and information from an on-board trip computer. At the least, the powertrain is able to optimize its operation to a driver's preference based on the feedback recorded along a particular route that the driver has specified. The route-learning powertrain control described herein is particularly useful with a hybrid powertrain, and can be used to optimize start/stop and regenerative braking control. The system described herein can also be integrated with a navigation system and GPS receiver, to provide more accurate route-learning and/or automated operation.
