Abstract
A sensing device for detecting a vehicle's skid, an attitude and a speed with lane markers. This sensing device allows sensors mounted on the vehicle to detect lane markers arranged on the lane center along a road. The lane markers are detected in a magnetic, electric, or optical manner. Based on outputs of the sensors, a movement of the vehicle is measured. Two sensors each are provided on front and rear of the vehicle. Four outputs from the respective sensors are calculated based on given equations (additions and subtractions) so that a skid amount of the vehicle from the lane center, the attitude and the speed of the vehicle can be found. This simple construction formed by the sensors detecting the lane markers and the circuits performing addition and subtraction can measure the skid, attitude and speed of the vehicle.
