| 20110006777 | ELECTRICAL LEAK DETECTING APPARATUS FOR AN ELECTRIC VEHICLE - The present invention relates to an electrical leak detecting apparatus for an electric vehicle, which is capable of not only detecting an electrical leak generated when a vehicle body is connected to the maximum potential or minimum potential of a battery pack, but also detecting which portion of the battery pack the vehicle body is connected to when an electrical leak is generated through the connection of the vehicle body and an intermediate potential of the battery pack. The electrical leak detecting apparatus for an electric vehicle according to the present invention includes: first and second switches connected to each other in series between a maximum potential terminal and a minimum potential terminal; a detection resistor having one end connected to a common contact of the first and second switches; and first and second measured potential supply units which are connected to each other in parallel between the other end of the detection resistor and the vehicle body, and which selectively provide first and second measured potentials, of different potential, to the battery pack. | 01-13-2011 |
| 20100324798 | ENGINE CONTROL METHOD FOR A VEHICLE WITH IDLE STOP FUNCTION - The present invention makes it possible to smoothly and quickly shift a transmission from a neutral position to a driving position and prevent a shift shock and a start delay by appropriately controlling an engine output when a vehicle with an idle stop function is started after an idle stop. | 12-23-2010 |
| 20100138120 | SHIFT CONTROL METHOD FOR AUTOMATIC TRANSMISSION IN FOUR-WHEEL DRIVE VEHICLE - The present invention relates to a method of controlling a shift of an automatic transmission of a four-wheel low-speed drive vehicle, in which when a four-wheel low-speed drive mode is selected, it is possible to accomplish an appropriate operational condition for the four-wheel low-speed drive mode that can realize a variety of operational conditions of the vehicle while effectively limiting additional use of memories for storing shift patterns, by controlling a shift point of the automatic transmission to be appropriate for the four-wheel low-speed drive mode with appropriate change in a basic shift pattern according to a basic operational condition to consider together with the four-wheel low-speed drive mode without separately using a specific shift pattern and by controlling the apply and release parts to be appropriate for the control of the shift point, thereby it is possible to ensure a stable and smooth shift. | 06-03-2010 |
| 20080253429 | Method for Detecting Fault of Oil Temperature Sensor for Automatic Transmission - A method for detecting a fault of an oil temperature sensor of an automatic transmission by using a determining means for detecting the fault of the oil temperature sensor. The method includes any one or more of the steps of 1) determining the fault of the oil temperature sensor by comparing minimum and maximum output values of the oil temperature sensor in every driving mode, 2) determining the fault of the oil temperature sensor by detecting abnormal excessive increase and decrease of the oil temperature for a specific duration, 3) determining the fault the oil temperature sensor in the stuck state in the driving mode when transmission oil temperature increases, and 4) determining the fault of the oil temperature sensor by detecting the oil temperature exceeding a predetermined temperature based on the time when the engine is left at a stopped state. | 10-16-2008 |
