Abstract
A method for controlling an electric motor of a battery-operated electric vehicle (BEV) includes receiving a signal for activating a drive slip control function for a braked start at full load of the BEV, supplying the electric motor with a predefined basic application of current while the BEV is in a braked state, and releasing a vibration mode by exciting the electric motor corresponding to a predetermined excitation scheme in addition to the predefined basic application of current. A battery-operated electric vehicle and a control device for a battery-operated electric vehicle are also disclosed.
Claims20
A method for controlling an electric motor of a battery-operated electric vehicle (BEV), the method comprising:
- receiving a signal for activating a drive slip control function for a braked start at full load of the BEV;
- supplying the electric motor with a predefined basic application of current while the BEV is in a braked state, wherein a body of the BEV is caused to be lowered in response to the predefined basic application of current;
- and
- triggering a vibration mode of the body of the BEV by excitation of the electric motor in accordance with a predefined excitation scheme in addition to the predefined basic application of current.
A battery-operated electric vehicle (BEV) comprising:
- a controller configured to:
- receive a signal for activating a drive slip control function for a braked start at full load of the BEV;
- supply an electric motor of the BEV with a predefined basic application of current while the BEV is in a braked state, wherein a body of the BEV is configured to be lowered in response to the predefined basic application of current;
- and
- trigger a vibration mode of the body of the BEV by excitation of the electric motor in accordance with a predefined excitation scheme in addition to the predefined basic application of current.
A controller for a battery-operated electric vehicle (BEV), wherein the controller is configured to:
- receive a signal for activating a drive slip control function for a braked start at full load of the BEV;
- supply an electric motor of the BEV with a predefined basic application of current while the BEV is in a braked state, wherein the controller is configured to cause a body of the BEV to be lowered in response to the predefined basic application of current;
- and
- trigger a vibration mode of the body of the BEV by excitation of the electric motor in accordance with a predefined excitation scheme in addition to the predefined basic application of current.
