Pedelec
A pedelec includes a drive unit with a drive motor, a battery which supplies the drive motor with power, a control unit having a motor control unit and an assist function determiner, and an operating unit informationally connected to the control unit. The motor control unit controls the power based on a reference variable and an assist function. The assist function determiner defines the power based on the reference variable and selects the assist function. The assist function determiner comprises a standard assist function memory storing a standard assist function, and a standard zone memory storing an upper and lower zone boundary of a zone criteria for applying the standard assist function. An assist function selected by the assist function determiner provides more power below the lower zone boundary and less power above the upper zone boundary. The operating unit adjusts the upper and/or lower zone boundary.
1. A pedelec comprising:
at least one wheel;
an electric pedelec drive unit comprising a drive motor which is configured to drive the at least one wheel;
a battery which is configured to supply the drive motor with an electric driving power;
a pedelec control unit comprising a motor control unit and an assist function determiner which is associated with the motor control unit, the motor control unit being configured to control the electric driving power for the drive motor based on a reference variable and an assist function, the assist function determiner being configured to define the electric driving power based on the reference variable and to select the assist function; and
an operating unit which is informationally connected to the pedelec control unit,
wherein,
the assist function determiner comprises,
an assist function which is stored in an assist function memory, and
an upper zone boundary and a lower zone boundary of a zone criteria for an applicability of the assist function, the upper zone boundary and the lower zone boundary of the zone criteria being stored in a zone memory,
an assist action selected by the assist function determiner results,
below the lower zone boundary, in a larger electric driving power than would be provided according to the assist function, and
above the upper zone boundary, in a smaller electric driving power than would be provided according to the assist function, and
the operating unit is configured to adjust at least one of the lower zone boundary and the upper zone boundary.
2. The pedelec as recited in claim 1 , further comprising:
a pedelec velocity sensor which is configured to determine a current velocity of the pedelec and whether the current pedelec velocity is the zone criteria.
3. The pedelec as recited in claim 2 , wherein the upper zone boundary is adjustable above an inflexible and absolute speed-regulating boundary.
4. The pedelec as recited in claim 1 , further comprising:
a pedal spindle; and
a pedal spindle rotational frequency sensor which is configured to determine a pedaling frequency of the pedal spindle,
wherein,
a pedal spindle rotational frequency is the zone criteria.
5. The pedelec as recited in claim 1 , further comprising:
a heart rate detector which is configured to determine a heart rate of a rider,
wherein,
the heart rate is the zone criteria.
6. The pedelec as recited in claim 1 , further comprising:
a pedaling torque sensor which is configured to determine a pedaling torque,
wherein,
the pedaling torque is the reference variable.
