US 11,447,123 B2 · Method and apparatus for controlling mild hybrid electric vehicle

Abstract

A method of controlling a mild hybrid electric vehicle may include determining whether a Start Stop Control (SSC) entrance condition is satisfied when a cruise mode is set; when the SSC entrance condition is determined to be satisfied by the control unit to enter an SSC mode, interrupting a supply of fuel to an engine and turning off the engine; monitoring a vehicle speed, in which when the engine is turned off, the control unit is configured to determine whether an acceleration control or a braking control of the vehicle is required based on a detection signal transmitted from a detecting unit electrically-connected to the control unit; and increasing or decreasing the vehicle speed by controlling the engine, a Mild Hybrid Starter Generator (MHSG), or an Electronic Stability Control (ESC) based on the monitoring of the vehicle speed.

A method of controlling a vehicle, the method comprising:

determining, by a control unit, whether a Start Stop Control (SSC) entrance condition is satisfied when a cruise mode is set;
in a response that the SSC entrance condition is determined to be satisfied by the control unit to enter an SSC mode, interrupting, by the control unit, a supply of fuel to an engine and turning off the engine;
monitoring, by the control unit, a vehicle speed, in which when the engine is turned off, the control unit is configured to determine whether an acceleration control or a braking control of the vehicle is required based on a detection signal transmitted from a detecting unit electrically-connected to the control unit;
and
increasing or decreasing, by the control unit, the vehicle speed by controlling the engine, a Mild Hybrid Starter Generator (MHSG), or an Electronic Stability Control (ESC) based on the monitoring of the vehicle speed.

An apparatus of controlling a vehicle, the apparatus comprising:

a detecting unit configured to output at least one detection signal among a vehicle speed signal, a front distance signal, an uphill/downhill signal, an accelerator pedal detection signal, and a brake pedal detection signal;
and
a control unit electrically-connected to the detecting unit and configured to receive the at least one detection signal, determine whether a cruise mode is set and the vehicle enters a Start Stop Control (SSC) mode, interrupt a supply of fuel to an engine when the cruise mode and the SSC mode are applied, and turn off the engine,
wherein the control unit is configured to determine whether an acceleration control or a braking control is required based on the at least one detection signal, and increases or decreases a vehicle speed by controlling the engine, a Mild Hybrid Starter Generator (MHSG), or an Electronic Stability Control (ESC) according to a result of determining whether the acceleration control or the braking control is required.
