摘要： PROBLEM TO BE SOLVED: To make it possible to freely set the voltage ratio of a power source at the input side of an inverter to the other power source connected between coils. SOLUTION: Output terminals of the inverter INV are connected to each terminal at both ends of coils L1, L2. A battery B is arranged between middle points of the coils L1, L2, and a capacitor C1 at the input side of the inverter INV. By adjusting the duty ratio of each transistor of the inverter INV, each input terminal of the coils L1, L2 is controlled independently, and thereby electric potentials at the middle points and phase currents of the coils L1, L2 are controlled. A current flows in such a way as to determine a voltage of the capacitor C1 so that the difference of the electric potentials at the middle points of the coil L1, L2 can become the same with the voltage of the battery B. As a result, the ratio of the voltage of the capacitor C1 to that of the battery B can be set freely. COPYRIGHT: (C)2004,JPO

解决方案：反相器INV的输出端子连接到线圈L1，L2两端的每个端子。电池B布置在线圈L1，L2的中间点和反相器INV的输入侧的电容器C1之间。通过调整反相器INV的各个晶体管的占空比，线圈L1，L2的每个输入端子被独立地控制，从而控制线圈L1，L2的中间点和相电流的电位。 A电流以确定电容器C1的电压的方式流动，使得线圈L1，L2的中点处的电位差可以与电池B的电压相同。结果，可以自由地设定电容器C1的电压与电池B的电压的比。版权所有（C）2004，JPO

摘要： PURPOSE:To avoid inconvenience in using detection values under the situation where a device has an abnormality by determining the abnormality in the device itself. CONSTITUTION:Since a tire air pressure never increases during run of a vehicle generally, it can be considered that it is not because the air pressure is abnormal but because a tire air pressure detection device is abnormal when a tire air pressure detection value increases during run of the vehicle. A device abnormality determination part 62 of a computer 47 therefore determines if tendency of increase is generated in the air pressure or not during run of the vehicle, and when it is, it is determined that the tire air pressure detecting device is abnormal to be informed to a driver by a display device 66.

摘要： PURPOSE:To obtain a wheel speed detector in which a periodic disturbance can be removed from the wheel speed. CONSTITUTION:An electromagnetic pickup 12 detects passage of a rotor 10, rotating with a wheel, through each tooth to produce a corresponding pulse signal. A computer 20 determines the rotational speed of wheel sequentially based on each pulse signal and a variation from the average value of a plurality of rotational speeds is stored sequentially, as a variation rotational speed, in a RAM 44. A variation rotational speed, determined just one revolution before the current variation rotational speed, is then selected among a plurality of prestored variation rotational speeds and the difference is determined thus removing a periodic error from the rotational speed.
