The invention discloses a constant-speed cruise system of an electric power-assisted bicycle. The invention belongs to the technical field of control systems. The system is composed of a torque sensor, a pedaling frequency sensor, a system controller ECU, a battery BMS and a manual brake handle. The whole system is controlled by a controller ECU program, torque of a torque sensor and pedaling frequency related information of a pedaling frequency sensor are collected, the related information such as torque, pedaling frequency, current and voltage is recorded through a memory of an ECU, when thetorque and the pedaling frequency are changed, the memory record is updated by new signal information, and once the output of the torque and the pedaling frequency is zero, the control system can control the system to keep the average speed of the first three seconds according to the parameters recorded by the ECU memory (or directly input by a user through an optional APP channel) to continue driving. When the hand brake works, the whole system can stop working. According to the system, the service life of the system can be prolonged and the working efficiency of the motor battery can be optimized and improved while people and vehicles interact in time.

    本发明公开了一种电动助力自行车定速巡航系统。属于控制系统技术领域;本发明由扭矩传感器,踏频传感器,系统控制器ECU,电池BMS,手动刹车把组成。整个系统由控制器ECU程序控制,其通过收集扭矩传感器的扭矩和踏频传感器踏频相关信息,通过ECU的储存器记录扭矩,踏频,电流,电压等这些相关信息,当扭矩和踏频发生变化时,储存器记录会被新的信号信息更新,一旦扭矩和踏频输出为0时,控制系统会根据ECU储存器记录的参数来控制系统保持前3秒状态的(或者由选配APP通道直接由用户输入)平均速度继续行驶。当手刹工作时,本系统整体会停止工作。本系统会使人与车及时互动的同时,会延长系统寿命,优化提高电机电池工作效能。
