Abstract
A mild hybrid vehicle and a method of controlling the same are provided. The mild hybrid vehicle includes a sensor that detects shift intention of a driver to provide the shift intention as sensing information, a controller that determines a target rotation speed of an MHSG based on the sensing information and controls the MHSG based on the target rotation speed, and the MHSG that controls the rotation speed of the engine under control of the controller when the shift intention is detected.
Claims19
A mild hybrid vehicle comprising:
- a sensor configured to detect shift intention of a driver to provide the shift intention as sensing information;
- a controller configured to:
- determine a target rotation speed of a mild hybrid starter and generator (MHSG) based on the sensing information;
- and
- control the MHSG based on the target rotation speed;
- and
- the MHSG configured to control a rotation speed of an engine when the shift intention is detected.
A method of controlling a mild hybrid vehicle, the method comprising:
- detecting a clutch pedal operation by a driver or a clutch operation;
- separating an engine and a transmission corresponding to the clutch pedal operation;
- disengaging a gear of the transmission when the engine and the transmission are separated;
- engaging the gear of the transmission with a gear different from or equal to a previous gear when the engine and the transmission are separated;
- and
- recoupling the separated engine and the separated transmission,
- wherein detecting the clutch pedal operation includes reducing an amount of regenerative power generation of a mild hybrid starter and generator (MHSG), and
- wherein each of separating the engine and the transmission, disengaging the gear of the transmission, and engaging the gear of the transmission includes controlling a rotation speed of the MHSG to allow the engine to reach a target rotation speed.
