Abstract
This motor driving control apparatus includes: a smoothing processing unit that executes smoothing processing using values of pedal input torque at plural points to calculate a first smoothed torque value; an insufficiency output unit that obtains a rate of points at which input of the pedal input torque is insufficient among the plural points; an assist torque calculating unit that performs calculation processing of mixing the first torque value calculated by the smoothing processing unit and the pedal input torque in accordance with output of the insufficient output unit to calculate assist torque; and a driving processing unit that performs processing to drive a motor using the assist torque calculated by the assist torque calculating unit.
Claims26
A motor driving control apparatus comprising:
- a memory;
- and
- a processor configured to use the memory and execute a process, the process comprising:
- executing smoothing processing using values of pedal input torque, which is inputted from a pedal of an electrically assisted bicycle, at a plurality of points to calculate a first smoothed torque value;
- calculating a rate of points at which the pedal input torque is zero among the plurality of points;
- first performing calculation processing of mixing the first smoothed torque value and the pedal input torque in accordance with the rate to calculate assist torque;
- and
- second performing processing to drive a motor of the electrically assisted bicycle using the assist torque.
A motor driving control apparatus comprising:
- a memory;
- and
- a processor configured to use the memory and execute a process, the process comprising:
- calculating, for a period corresponding to one cycle of a torque request whose cycle is variable, a moving average or weighted moving average of the torque request to generate a smoothed torque request;
- performing calculation processing using the smoothed torque request and the torque request to calculate a target torque corresponding to the torque request;
- and
- performing processing to drive a motor in a vehicle using the target torque.
