  • Publication number: 20190300105
    Abstract: 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.

  • Patent number: 9857252
    Abstract: 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.

  • Patent number: 9828060
    Abstract: A method may include determining whether a sweat sensor is available. E-assist may be provided when a sweat sensor is not available by determining a sweat threshold and determining whether the sweat threshold is surpassed. When a sweat sensor is available, e-assist may be provided when the sweat sensor senses sweat.

  • Patent number: 9767655
    Abstract: 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.

  • Patent number: 9527495
    Abstract: 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.

  • Patent number: 9241249
    Abstract: Computer-implemented methods, systems and apparatus are disclosed for providing notification at an automotive head unit (AHU) of a vehicle that a pre-paired consumer electronics device (CED), such as a wireless communication device, is outside a vehicle. When it is determined that the pre-paired CED is not connected to a wireless communication interface of the AHU, a notification can be provided to the AHU indicating that the pre-paired CED is not connected. Positional data from a location message, provided from the pre-paired CED, can then be processed to generate location data and provide the location data to the AHU.

  • Patent number: 9227595
    Abstract: Computer-implemented methods, systems and apparatus are disclosed for providing a notification when a vehicle has been accessed by an unauthorized person. An onboard computer system of a vehicle is activated in response to a trigger event indicating that the vehicle has been accessed. It is determined whether an authorized consumer electronics device (CED), that is associated with an authorized person, is connected to a wireless communication interface of an onboard computer system. When an authorized CED has not connected to the wireless communication interface, a notification message is communicated that indicates that the vehicle has been accessed and that an authorized CED has not connected to the wireless communication interface.
