Publication number: 20190300105Abstract: A pedal electric cycle (e-bike) includes a road wheel connected to a frame, a crankset imparting a rider torque to the road wheel when a rider manually rotates the crankset, a battery pack having a state of charge (SOC), an electric traction motor, and a controller. In response to motor control signals, the motor imparts an electric-assist (e-assist) torque to the road wheel as a torque multiplier. The controller uses an energy cost function, and in response to input signals including a travel route and a desired e-assist objective, commands the e-assist torque via the motor control signals to augment the rider torque while satisfying the e-assist objective. The level is determined via the energy cost function, with the input signals including the SOC, inclination data describing a grade of each road segment of the route, and an electric model providing the torque multiplier.Type: ApplicationFiled: March 28, 2018Publication date: October 3, 2019Applicant: GM Global Technology Operations LLCInventors: Shaun S. Marshall, Mark A Manickaraj, Andrew M. Zettel, Prakash Murugesan

Patent number: 9857252Abstract: A system for, and method of, providing e-assist on a route. A determination may be made of whether terrain data for the route is available. A rider effort level may be determined. The terrain data may be read when available. Whether a change in slope has occurred, or is anticipated to occur, corresponding to a need for an additional input to the rider effort level may be determined. The e-assist level may be adjusted to provide a level that offsets the need for the additional input, or the rider may be informed to provide an increased effort level.Type: GrantFiled: November 24, 2015Date of Patent: January 2, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Prakash Murugesan, Mark A.

Patent number: 9767655Abstract: Computer-implemented methods, systems and apparatus are disclosed for providing notification at a vehicle that a pre-paired consumer electronics device (CED) has been left inside the vehicle. The vehicle includes a processor and a vehicular system controllable via the processor. The processor can receive an alert signal that indicates that a pre-paired CED has been left inside the vehicle during a time period after a trigger event has occurred. The processor is further configured to control activation of the vehicular system, in response to receiving the alert signal, to cause the vehicular system to generate another signal that is perceptible outside the vehicle to indicate that the pre-paired CED has been left inside the vehicle.Type: GrantFiled: October 31, 2013Date of Patent: September 19, 2017Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Linxuan Yang, Jarvis Chau, Mark A.

Patent number: 9527495Abstract: A vehicle system includes an electric motor, an internal combustion engine, and a heating system configured to transfer heat from the internal combustion engine to a passenger compartment of the vehicle. The system includes a controller configured to operate the electric motor and the internal combustion engine according to one of a plurality of drive cycle profiles. The controller selects the drive cycle profile based on an ambient temperature. The drive cycle profiles include a first drive cycle profile that commands power from the electric motor until the battery system reaches a predetermined state of charge and subsequently commands power from the internal combustion engine and a second drive cycle profile that commands power from the internal combustion engine and subsequently commands power from the electric motor.Type: GrantFiled: December 11, 2014Date of Patent: December 27, 2016Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Andrew M.
