摘要： A vehicle-direction detecting apparatus compensates for the direction detected by each sensor to provide a correct direction. A difference signal between the first direction signal based on the XY output signal of a geomagnetic sensor and the second direction signal acquired by integrating the output signal of an angular velocity sensor is computed, it is discriminated whether or not an absolute value signal of the difference signal is greater than a first predetermined value, it is discriminated whether or not the output signal of differentiating means which has differentiated the absolute value signal is greater than a second predetermined value, it is discriminated whether or not the XY output signal of the geomagnetic sensor has a value within a predetermined range, and the first or second direction signal is compensated for in accordance with the results of the above discriminations. Even if the declination or the magnetic center point varies, or the offset of the angular velocity sensor varies, the direction detected by each sensor will be compensated accordingly.

摘要： An automotive mileage calculating apparatus of this invention consists of a vehicle speed sensor, an acceleration sensor, a slip detecting circuit, and a mileage calculating circuit. The slip detecting circuit detects a wheel slip either by comparing the accelerations calculated from the vehicle speed sensor's speed signal and from the acceleration sensor's acceleration signal; by comparing the vehicle speeds calculated from the vehicle speed sensor's speed signal and from the acceleration sensor's acceleration signal; or by comparing the mileages calculated from the vehicle speed sensor's speed signal and from the acceleration sensor's acceleration signal. During normal running, the mileage is calculated by using the speed sensor's speed signal. When a wheel slip is detected, the mileage calculation is performed by using the acceleration sensor's acceleration signal, thus giving a correct mileage.
