Abstract
A method of and an apparatus for controlling MHSG of a mild hybrid electric vehicle may include: detecting data for controlling the MHSG; determining whether an entry condition of coasting is satisfied based on the data; releasing a shift clutch of a transmission when the entry condition of coasting is satisfied; determining whether a release condition of coasting is satisfied in a state in which the mild hybrid electric vehicle is coasting; determining a target speed of an engine when the release condition of coasting is satisfied; and controlling the MHSG such that a speed of the engine increases to the target speed.
Claims15
A method of controlling a mild hybrid starter & generator (MHSG) of a mild hybrid electric vehicle, the method comprising:
- detecting data for controlling the MHSG;
- determining whether an entry condition of coasting is satisfied based on the data;
- releasing a shift clutch of a transmission when the entry condition of coasting is satisfied;
- determining whether a release condition of coasting is satisfied when the mild hybrid electric vehicle is coasting;
- determining a target speed of an engine when the release condition of coasting is satisfied;
- and
- controlling the MHSG such that a speed of the engine increases to the target speed,
- whether the release condition of coasting is satisfied is determined based on position value of an accelerator pedal, a position value of a brake pedal, a speed of the mild hybrid electric vehicle, a current gear stage, and a gradient of a road.
An apparatus for controlling a mild hybrid starter & generator (MHSG) of a mild hybrid electric vehicle, the apparatus comprising:
- a data detector detecting data for controlling the MHSG that starts an engine or generates electricity by an output of the engine;
- and
- a controller configured for determining whether an entry condition of coasting based on the data, and releasing a shift clutch of a transmission when the entry condition of coasting is satisfied, wherein the controller is configured to determine whether a release condition of coasting is satisfied when the mild hybrid electric vehicle is coasting, is configured to determine a target speed of the engine when the release condition of coasting is satisfied, and is configured to control the MHSG such that a speed of the engine increases to the target speed,
- wherein the controller is configured to determine whether the release condition of coasting is satisfied based on a position value of an accelerator pedal, a position value of a brake pedal, a speed of the mild hybrid electric vehicle, a current gear stage, and a gradient of a road.
