摘要： A method for controlling a vehicle in the event of an oil-pump failure may include: a first comparison step of comparing, by a controller, an actual RPM of an EOP with a first set value set in advance based on a target RPM of the EOP; a maximum EOP driving step of driving the EOP to a maximum output by the controller when a result of the comparison in the first comparison step shows that the actual RPM is smaller than or equal to the first set value; a second comparison step of comparing the actual RPM of the EOP with a second set value by the controller after the maximum EOP driving step; and a creep driving step of making the vehicle perform creep driving using a motor by the controller when a result of the comparison in the second comparison step shows that the actual RPM is larger than the second set value.

摘要： A method and a system for diagnosing insufficiency of vehicle coolant includes a preparing step of checking whether the vehicle is in a stop state and is on flat ground. An operating step applies a predefined output to a coolant water pump when the vehicle is in the stop state and is on flat ground. A measuring step measures a rotation speed of an impeller of the coolant water pump for a period in which the predefined output is applied to the coolant water pump. A M determining step compares the measured rotation speed of the impeller of the coolant water pump with a reference speed to determine whether or not the coolant is insufficient.

摘要： A method of controlling charging of a battery may include making, by a controller, the battery that supplies power to a drive motor start to be charged with a boosted voltage higher than a voltage of a fast charger by controlling a switch connecting the drive motor and the fast charger of a vehicle and a switch of an inverter driving the drive motor, for fast charging of the battery; determining, by the controller, whether a motor position sensor has failure according to an output signal of the motor position sensor which detects a position of the drive motor; engaging, by the controller, an engine clutch that is configured to connect or disconnect the engine of the vehicle and the drive motor, when the controller determines that the motor position sensor has the failure; and maintaining, by the controller, the fast charging for the battery when a rotation of the drive motor stops after the engine clutch is engaged.
