A method for measuring a slope angle of a vehicle includes, by a controller: determining whether or not a speed of the vehicle is 0 based on a speed signal received from a vehicle speed sensor of the vehicle; measuring an extremal value measured first, an extremal value measured second, and an extremal value measured third among extremal values of an output signal of an acceleration sensor detecting a signal corresponding to the slope angle of the vehicle when the speed of the vehicle is 0; verifying whether or not the measured three extremal values satisfy conditions of the extremal values based on reference conditions of each of the extremal values; estimating a steady state value of the output signal of the acceleration sensor, based on the extremal values measured first and second among the verified three extremal values and a dynamic characteristic parameter of the vehicle or based on the verified three extremal values; and converting the steady state value into the slope angle of the vehicle. The output signal of the acceleration sensor has a damped free vibration waveform.

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.

An idle stop and go (ISG) control method for a vehicle provided with a manual transmission includes: determining, by a controller, whether a first operation determination condition is satisfied based on a bottom signal from a clutch pedal sensor, a brake pedal operation signal, and a first vehicle speed signal condition; determining, by the controller, whether a second operation determination condition is satisfied based on the bottom signal, the brake pedal operation signal, and a second vehicle speed signal condition; stopping, by the controller, an engine of the vehicle when the first operation determination condition or the second operation determination condition is satisfied; determining, by the controller, whether a first restart condition is satisfied based on a top signal or the bottom signal from the clutch pedal sensor; and restarting, by the controller, the engine when the first restart condition is satisfied.

Control method for ISG of vehicle equipped with manual transmission

An automatic opening and closing device for a fuel inlet of a vehicle may include a cap cover mounted at the fuel inlet of the vehicle, a fuel cap pivotably mounted at the cap cover and configured to selectively open or close the fuel inlet by being pivoted inside the fuel inlet, and a fuel cap operating mechanism mounted in the fuel inlet and configured, when the fuel door is closed, to pivot the fuel cap by being pressed by the fuel door to close the fuel inlet, and, when the fuel door is opened, pivot the fuel cap to open the fuel inlet according to release of pressing by the fuel door.

A method for controlling a vehicle includes: receiving a detection signal required to perform an idle stop and go (ISG) function; and controlling the vehicle to enter into an ISG state where a fuel supply to an engine is cut off and the engine stops when the vehicle decelerates or stops in response to the detection signal. The detection signal includes a fuel cut off signal in on state when the vehicle decelerates and in off state at a reference revolution number of the engine, a gear engagement signal, a clutch pedal signal indicating whether a clutch pedal operating a clutch is operated, and a brake pedal signal indicating whether a brake pedal is operated. A controller generates an ISG entry signal based on the fuel cut off signal, the gear engagement signal, the clutch pedal signal, and the brake pedal signal to enter the vehicle into the ISG state.

A method for controlling a vehicle includes: receiving a detection signal to perform an idle stop and go (ISG) function; and controlling the vehicle to enter into an ISG state where a fuel supply to an engine is cut off and the engine stops when the vehicle decelerates or stops in response to the detection signal. The detection signal includes a fuel cut off signal that is in on state when the vehicle decelerates and in off state at a reference revolution per minute (RPM) of the engine, a gear engagement signal, and a brake pedal signal indicating whether the brake pedal of the vehicle is operated. A controller of the vehicle generates an ISG entry signal based on the fuel cut off signal, the gear engagement signal, and the brake pedal signal to enter the vehicle into the ISG state.
