Patent number: 5477220Abstract: To detect the relative travel direction of a vehicle, the distances (A, B) traveled by the right front wheel and the left front wheel of the vehicle are detected, the turning angle (.theta.) of the vehicle is calculated only on the basis of the travel distances of the right front wheel and the left front wheel, the tread width (T) and the wheelbase (W) of the vehicle, whereby the relative travel direction is detected.Type: GrantFiled: June 24, 1992Date of Patent: December 19, 1995Assignee: Zexel CorporationInventor: Masataka Ishikawa

Patent number: 5390123Abstract: A navigation system having two sensors and two circuits. A travel sensor sends a pulse whenever a vehicle travels a predetermined distance. An angular velocity sensor outputs a voltage corresponding to an angular velocity of the vehicle. A correction circuit calculates the angular velocity from both a reference voltage that corresponds to an angular velocity of zero and an output voltage from the angular velocity sensor. A reference voltage resetting circuit monitors the pulse from the travel sensor; sets, as an effective sampling interval, at least a part of a interval from the end of a predetermined first cancellation interval after the pulse stops until the start of a second cancellation interval prior to a resumption of the pulse; calculates an average value of the output voltage of the angular velocity sensor, which has been periodically sampled during the effective sampling interval; and resets the reference voltage to the average value.Type: GrantFiled: June 9, 1992Date of Patent: February 14, 1995Assignee: Zexel Corporation Daihatsu-NissayInventor: Masataka Ishikawa

Patent number: 5343400Abstract: Travel locus vectors of a vehicle are calculated at prescribed time intervals on the basis of data related to the rotational angle of a pair of wheels of the vehicle. The relative travel direction of the vehicle is detected on the basis of the travel locus vectors. The prescribed time intervals are changed in response to at least one traveling condition of the vehicle selected from its traveling speed and its turning angle.Type: GrantFiled: June 19, 1992Date of Patent: August 30, 1994Assignee: Zexel CorporationInventor: Masataka Ishikawa

Patent number: 5297028Abstract: An angular rate sensor for a vehicle navigation system stores an environmental temperature and a related null voltage each time the vehicle stops. The pairs of data points are stored in a non-volatile look-up table for use during vehicle motion. During vehicle motion, the environmental temperature is measured, and a null voltage is selected from the look-up table corresponding to the measured temperature. The null voltage is used to correct drift offset. Interpolation is used when data keyed to the measured temperature cannot be found in the look-up table.Type: GrantFiled: August 27, 1991Date of Patent: March 22, 1994Assignee: Zexel Corporation Daihatsu-NissanInventor: Masataka Ishikawa
