Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent a bicycle from overturning, by inputting output from a second multi-vibrator and output from second and third NAND circuits, and by placing forth and fifth NAND circuits which output driving signals to a motor driving circuit. SOLUTION: By output 'H' from a first single stable multi-vibrator 22 and output 'H' from a parking circuit 23, output from a NAND circuit 24 becomes 'L'. The output 'L' from a NAND circuit 24 is input into a single stable multi- vibrator 27, and counting is started. During this counting, the second single stable multi-vibrator 27 outputs 'L', and NAND circuits 28, 29 output 'H'. Therefore, brake mode is input into a driving circuit 14, and a bicycle is braked. If a microcomputer runs away during running of the bicycle, the bicycle is braked without going into parking mode, and any accident that the bicycle overturns is avoided.
