Abstract: There are provided an apparatus and a method for controlling power of a vehicle. The apparatus for controlling power of a vehicle includes: a first load and a second load; a first power supply supplying power to at least one of the first load and the second load from a main battery; a second power supply supplying power to at least one of the first load and the second load from an auxiliary battery supplied with and charged by the power from the main battery; a switch set including a plurality of switches intermitting lines between the first load, the second load, the first power supply, and the second power supply; and a power controller checking a state of the vehicle and controlling a turn-on or off for the plurality of switches in response to the checked state of the vehicle.

Abstract: The present invention relates detecting the rotation speed of tires for a vehicle. In the present invention, signals are received from a plurality of wheel speed sensors, a reverse gear sensor, and a brake sensor. Errors of the wheel speed sensors are estimated using the received signals, a signal having a corrected error is obtained using the estimated errors, linear interpolation. Accordingly, there is an advantage in that rotation speed of tires for a vehicle can be determined accurately.

Abstract: The present invention relates detecting the conditions of tires for a vehicle. In the present invention, signals are received from a plurality of wheel speed sensors, a reverse gear sensor, and a brake sensor. Errors of the wheel speed sensors are estimated using the received signals, a signal having a corrected error is obtained using the estimated errors, linear interpolation and band-pass filtering processing are performed on the signal, a tire resonant frequency is estimated using the processed signal, tire pressure is estimated based on the estimated resonant frequency, and whether or not to generate an alarm is determined based on the calculated tire pressure. Accordingly, there is an advantage in that whether or not pressure within a tire of a vehicle is abnormal can be determined in a cheap calculation device for a short time using a conventional wheel speed sensor.
