Abstract
A method for training an automatic gear unit of a two-wheeled vehicle and/or a device, as well as a two-wheeled vehicle having such a device modifies an existing characteristic map for the control of the gear unit based on the individual user information. Optionally, it is also possible to set up a characteristic map for the control of the gear unit with the aid of the method in that the user information is recorded during gear-change operations and utilized for further automatic gear-change operations.
Claims9
A method for training an automatic gear unit of a two-wheeled vehicle, the method comprising:
- acquiring at least:
- (i) a first rotational frequency variable representing a rotational frequency of a pedal crank of the two-wheeled vehicle, (ii) a torque variable representing a torque applied by a rider to the pedal crank, and (iii) an engaged gear of an automatic gear unit;
- and
- performing a gear-change operation to an automatic gear as a function of the first rotational frequency variable, the torque, and the engaged gear with the aid of a characteristic map;
- detecting a first manual gear-change request of the rider;
- performing a gear-change operation to a first target gear as a function of the gear-change request;
- and
- modifying the characteristic map by allocating the first target gear to the acquired rotational frequency variable and to the acquired torque.
A device for training an automatic gear unit of a two-wheeled vehicle having a control unit and a memory, the control unit configured to:
- acquire:
- (i) a first rotational frequency variable representing a rotational frequency of a pedal crank of the two-wheeled vehicle, (ii) a torque variable representing a torque applied to the pedal crank by a rider, and (iii) an engaged gear of the gear unit;
- generate a control signal for carrying out a gear-change operation to an automatic gear as a function of the rotational frequency variable, the torque, and the engaged gear based on a characteristic map stored in the memory;
- detect a first manual gear-change request by the rider;
- generate a further control signal for carrying out a gear-change operation to a first target gear as a function of the gear-change request;
- and
- modify the characteristic map in the memory by allocating the first target gear to the acquired rotational frequency variable and the acquired torque.
A two-wheeled electrically drivable bicycle, comprising:
- an automatic gear unit;
- and
- a device for training the automatic gear unit of a two-wheeled bicycle, the device having a control unit and a memory, the control unit configured to:
- acquire:
- (i) a first rotational frequency variable representing a rotational frequency of a pedal crank of the two-wheeled bicycle, (ii) a torque variable representing a torque applied to the pedal crank by a rider, and (iii) an engaged gear of the automatic gear unit;
- generate a control signal for carrying out a gear-change operation to the automatic gear as a function of the rotational frequency variable, the torque, and the engaged gear based on a characteristic map stored in the memory;
- detect a first manual gear-change request by the rider;
- generate a further control signal for carrying out a gear-change operation to a first target gear as a function of the gear-change request;
- and
- modify the characteristic map in the memory by allocating the first target gear to the acquired rotational frequency variable and the acquired torque.
