PURPOSE:To measure the angle of inclination of a motor bicycle during running without receiving the influence of centrifugal force by constituting a device of the 1st and 2nd acceleration sensors, a vehicle speed sensor and an arithmetic device. CONSTITUTION:An arithmetic device is connected with the outputs A1, A2 of the 1st and 2nd acceleration sensors and the output (v) of a vehicle speed sensor, calculates the angle theta2 of inclination of a vehicle body in accordance with the equation and outputs the same. The acceleration sensors 1, 2 are the sensors which detect the acceleration in the direction intersecting orthogonally with the central surface of the vehicle body and the accelerations A1, A2 detected by the same are inputted to the channels ch1, ch2 of an A/D converter 5. The vehicle speed pulse detected by the vehicle speed sensor 3 is converted to the voltage (v) proportional to the vehicle speed by an FV converter 4 and is thereafter inputted to the channel ch3 of the converter 5. The analog quantity inputted to the channels ch1-ch3 is converted to a digital quantity in the converter 5 and thereafter the values thereof are inputted to a microcomputer 6. The value of theta2 outputted from the microcomputer 6 is converted to analog quantity by a D/A converter 7 and is thereafter displayed. |
