Abstract
A hybrid electric vehicle and a vibration control method thereof is provided. The vibration control method of the hybrid electric vehicle includes: receiving rotor angle information of a motor generated based on information detected by a resolver; receiving first engine rotation-angle information of an engine generated based on information detected by a cam angle sensor or a crank angle sensor; generating engine rotation-angle candidates based on the rotor angle information; and identifying a second engine rotation-angle based on the engine rotation-angle candidates and the first engine rotation-angle information.
Claims8
A vibration control method of a hybrid electric vehicle, the vibration control method comprising:
- receiving rotor angle information of a motor of the hybrid electric vehicle generated based on information detected by a resolver;
- receiving first engine rotation-angle information of an engine of the hybrid electric vehicle generated based on information detected by a cam angle sensor or a crank angle sensor;
- generating a plurality of engine rotation-angle candidates based on the rotor angle information, wherein the number of the plurality of engine rotation-angle candidates is determined based on a number of poles of a motor rotor magnet of the hybrid electric vehicle and regardless of a pulse resolution of the crank angle sensor;
- identifying a second engine rotation-angle based on the number of engine rotation-angle candidates and the first engine rotation-angle information;
- and
- controlling the engine based on the second engine rotation-angle.
A hybrid electric vehicle comprising:
- one or more rotor-angle operation units configured to generate rotor angle information of a motor of the hybrid electric vehicle based on information detected by a resolver;
- an engine rotation-angle operation unit configured to generate first engine rotation-angle information of an engine of the hybrid electric vehicle based on information detected by a cam angle sensor or a crank angle sensor;
- and
- a synchronization operation unit configured to generate a plurality of engine rotation-angle candidates based on the rotor angle information, wherein the number of the plurality of engine rotation-angle candidates is determined based on a number of poles of a motor rotor magnet of the hybrid electric vehicle and regardless of a pulse resolution of the crank angle sensor, to identify a second engine rotation-angle based on the number of engine rotation-angle candidates and the first engine rotation-angle information, and to control the engine based on the second engine rotation-angle.
