Brake system and method

A brake system of a bicycle, comprising:

• a brake device;
• a plurality of brake sensors;
• and
• an electronic apparatus positioned on a bracket of the bicycle, the electronic apparatus comprising an electronic level instrument, an accelerometer, a storage system, at least one processor;
• and
• one or more programs stored in the storage system and being executable by the at least one processor, the one or more programs comprising:
• an adjustment module that adjusts the bracket to make the electronic apparatus be in a horizontal state using an electronic level instrument of the electronic apparatus;
• a detection module that marks slopes on an electronic map provided by a global position system (GPS) of the electronic apparatus, and determines whether a gradient value of the electronic apparatus detected by the accelerometer exceeds or equals a predetermined gradient value under the condition that the bicycle is determined to be descending by comparing position information acquired from the GPS when the bicycle reaches the marked slopes;
• a determination module that determines whether the bicycle is braking improperly according to brake operations detected by the plurality of brake sensors when the gradient value exceeds or equals the predetermined gradient value, and determines that the bicycle is braking improperly when front brakes of the brake device are operated prior to operations of the rear brakes;
• and
• a command module that sends a brake command to the brake device to terminate an improper brake operation when the bicycle is braking improperly, and tightens and then loosens brake cables of a front wheel and a rear wheel of the bicycle repeatedly for a predetermined number times within a predetermined time period by the brake device according to the brake command.

A non-transitory storage medium storing a set of instructions, the set of instructions capable of being executed by a processor to perform a brake method of a bicycle using a brake system, the brake system comprising an electronic apparatus positioned on a bracket of the bicycle, a brake device, and a plurality of brake sensors, the method comprising:

• adjusting the bracket to make the electronic apparatus be in a horizontal state using an electronic level instrument of the electronic apparatus;
• marking slopes on an electronic map provided by a global position system (GPS) of the electronic apparatus;
• determining whether a gradient value of the electronic apparatus detected by an accelerometer of the electronic apparatus exceeds or equals a predetermined gradient value under the condition that the bicycle is determined to be descending by comparing position information acquired from the GPS when the bicycle reaches the marked slopes;
• determining whether the bicycle is braking improperly according to brake operations detected by the plurality of brake sensors, when the gradient value exceeds or equals the predetermined gradient value;
• determining that the bicycle is braking improperly when front brakes of the brake device are operated prior to operations of the rear brakes, and sending a brake command to the brake device to terminate an improper brake operation;
• and
• tightening and then loosening brake cables of a front wheel and a rear wheel of the bicycle repeatedly for a predetermined number times within a predetermined time period using the brake device according to the brake command.
