Riding safety protection system of power assisted bicycle

Abstract

The invention relates to a riding safety protection system of a power assisted bicycle. The riding safety protection system of the power assisted bicycle comprises a power module, a microcomputer electrically connected to the power module, a gear-shifting driver and an upper control panel electrically connected to the microcomputer. The upper control panel is provided with at least one input piece, wherein a rider operates the input piece so that an order can be input into the microcomputer; the microcomputer is provided with a plurality of power assisting modes and a type of power assisting mode logic and the condition that which power assisting mode is adopted is judged by the microcomputer according to the power assisting mode logic; the microcomputer is further provided with a type of order input judgment logic, whether the order is input or not is judged by the microcomputer according to the order input judgment logic, when the order is input, the power assisting mode logic is eliminated in a preset time section, the switch of the power assisting modes is not conducted, and after a first condition is satisfied, the power assisting mode logic is executed again.

Description

technical field [0001] The invention is related to the gear shifting system of a bicycle, in particular to a riding safety protection system for an assist bicycle. Background technique [0002] Existing bicycles with automatic shifting function usually put a shifting logic in their microcomputer. When the shifting condition of the shifting logic is reached, for example, when the speed of the vehicle reaches a predetermined speed, the microcomputer controls the corresponding transmission. When shifting gears, the rider will feel that the pedaling load and pedaling frequency have changed because the shifting action changes the gear ratio when pedaling. In addition, an upper control panel is usually provided on the handlebar of an existing bicycle with an automatic shift function, and the upper control panel has control buttons for the rider to set or operate related riding states or riding conditions, such as operating power Switch, power switch or light switch, or set the di...

Problems solved by technology

[0004] However, the opportunity for the rider to operate the upper control panel mostly occurs during riding. When the rider operates the upper control panel, he will focus on the upper control panel or the upper control panel in an instant. If the microcomputer judges that the power-assisted mode should be changed and changes the power-assisted mode, or judges that the gear should be changed and performs a gear shift action, then the rider will be distracted by focusing on the upper control panel. Being disturbed by a sudden power boost change or shifting action will cause the rider's psychological discomfort or mistakes in the pedaling action, and serious cases may even cause danger
