Abstract

PURPOSE:To allow a rider to drive comfortably, by detecting the driving state particularly the driving speed of a bicycle with a speed change gear, and displaying the optimum change gear position suitable for the driving state. CONSTITUTION:A timer circuit 6 outputs intermittently the output within a certain period and opens a gate 5 only for a certain period. During that period, only speed pulses outputted from a speed pulse detector 7 are inputted in a counter 4 to be counted. When the counting is finished, the counter 7 outputs to a latch 3, the latch 3 retains that value until the next completed count value is outputted and the latch 3 outputs to an address assigning terminal of a memory apparatus 2. The memory apparatus 2 assigns an address depending on the counted value, and reads out an optimum speed change stage in the involved storage address to be outputted to a display 1. Thus the optimum speed change stage suitable for the current driving speed of the bicycle is displayed and therefore the rider can select the suitable speed change gear position to drive comfortably.

備えるものである。The present invention relates to a bicycle equipped with a transmission, and is equipped with a display device that detects the running condition of the bicycle, particularly the running speed of the bicycle, and displays the gear shifting position most suitable for the riding condition.

し、効率の悪いペダリングとなる。Conventional configuration and its problems In bicycles with conventional gear shifting devices, the selection of the current position is simply left to the rider's will, and the rider performs gear shifting operations based on experience and intuition. , it is impossible to accurately determine the appropriate shift position.0 When running uphill or driving into a headwind, when running resistance increases, the leg strength cannot overcome it, resulting in a decrease in pedal rotation speed and poor efficiency. It becomes pedaling.

をも目的とする。In order to achieve this, it is necessary to reduce the gear ratio to reduce the burden on the legs.In addition, when the load on the legs is too light, such as when riding on flat ground, the pedal rotation speed is too high and the legs are strained. The rotation of the legs cannot keep up with this, resulting in inefficient pedaling.In this case, increasing the gear ratio will ensure that the load is not appropriate and the rotation of the legs can be kept constant, resulting in less tiring pedaling.Invention The present invention enables comfortable driving by displaying and informing the occupants of the optimum shift position according to the driving conditions. Another purpose of the present invention is to enable the user to select a gear shifting position according to his or her physical strength.

表示することができる。Components of the Invention The number of pedal rotations of the occupant is constantly detected, and if the number of rotations decreases, it is considered that the load on the legs has increased, and the load is reduced, and if the number of rotations increases, the load is shifted to the opposite direction. By instructing the optimum shift position to change the shift position in each direction, the pedal rotation speed will always be constant and efficient riding will be possible.Furthermore, factors such as the slope of the hill and the wind speed relative to the bicycle can be adjusted. If this is taken into account, a more appropriate shift position can be displayed.

The data contents are stored in a storage device, and while the vehicle is running, these driving state data are sent to the storage device as an address, and the contents of the address, that is, the optimum shift position are displayed.
