Abstract

The invention discloses a hilly-area electric power bicycle. The hilly-area electric power bicycle is characterized by comprising a bicycle body (1), an electric power device (2), a pedal force detecting device (3) and a control device (4), wherein the electric power device is installed on the bicycle body (1) and used for providing auxiliary driving force for the bicycle body (1), the pedal force detecting device (3) is installed on the bicycle body (1) and used for detecting pedal force moment to produce corresponding force moment signals, the control device (4) is installed on the bicycle body (1) and used for receiving the force moment signals, and control signals which correspond to the force moment signals are produced to control the auxiliary driving force which is provided by the electric power device (2) and corresponds to the pedal force moment. According to the size of pedal force of a rider, output power of a motor is ensured by the electric power bicycle, the motor is enabled to provide the auxiliary driving force which corresponds to the pedal force. The hilly-area electric power bicycle is high in electrical energy utilization rate, low in power consumption, safe and suitable.

Description

technical field [0001] The invention relates to a mountain bike, in particular to a mountain bike with electric assist and an electric assist method thereof. Background technique [0002] With the increasing global attention to environmental issues and the promulgation of relevant environmental protection laws and regulations, traditional lead-acid batteries and downstream lead-acid electric vehicles are increasingly subject to more restrictions, and pure electric vehicles have high power consumption, high The failure rate and high accident rate are also criticized by people. Afterwards, Ni-MH battery-assisted bicycles and lithium-ion battery-assisted bicycles were successively launched in the market. However, due to the technical limitations of supporting components, especially the speed-type signal is used as the main power-assisted system, their energy efficiency is still low; Concentrating on urban vehicles, these have greatly restricted the development of electric powe...
