  • Method for determining the course of a land vehicle by comparing signals from wheel sensors with signals of a magnetic sensor
    Patent number: 5487009
    Abstract: In a method for determining the location of a land vehicle wherein the driving distance and course changes are derived from wheel pulses generated by sensors in the course of the revolution of the wheels of a vehicle axle by respectively a preset angle, the course changes derived from the wheel pulses are compared with comparison course changes which are obtained independently of the wheel pulses. Correction values are derived from the result of the comparison. The comparison course changes are preferably detected with the aid of a magnetic sensor (compass).
