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.

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.

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.
