Embodiment 1

[0040] The electric power-assisted bicycle provided by the present invention comprises a vehicle frame, (front and rear) wheels supporting the vehicle frame, a handlebar for turning the front wheels, a pedal transmission mechanism for driving the rear wheels, a motor 3 and a motor controller. The motor 3 can indirectly drive the wheel to rotate through a reduction gear, a chain, a belt, etc.

[0041] Such as figure 1 As shown, the electric power-assisted bicycle provided by the present invention also includes: an instrument panel 2 with a built-in signal processor, and a speed control handle 1 .

[0042] The speed-regulating handle 1 is connected to the signal processor, and the speed-regulating handle 1 suitable for the present invention can adopt the following structure: it includes a rotatable handle and a fixed seat cover, and the rotatable handle is sleeved on the fixed seat cover; the fixed seat cover There is a Hall element inside, which is electrically connected with ...

Embodiment 2

[0056] Such as figure 2 As shown, it is the embodiment of the second electric power-assisted bicycle provided by the present invention, which is different from Embodiment 1 in that: the battery and the battery management system are respectively connected to the signal processor through a power line and a digital communication line; The signal processor estimates the state of health of the battery, the remaining power of the battery and or the remaining cruising range according to the output power of the motor 3 and the battery-related information output by the battery management system, and outputs and displays the estimated results through the dashboard 2 . If a wheel speed sensor is provided, the wheel speed sensor is connected with the motor controller.

[0057] The battery-related information output by the battery management system includes the battery device number. The signal processor detects whether the battery has been replaced according to the battery device number....

Abstract

The invention discloses an electric power-assisted bicycle and a drive method thereof. The electric power-assisted bicycle comprises a motor controller, a motor used for driving wheels to rotate, a speed regulation rotation handle and a pedal torque sensing mechanism. The drive method comprises the following steps of selecting motor drive modes including a power-assisted drive mode and a pure electric drive mode which are mutually standby; if selecting the power-assisted drive mode, regulating an output torque or a rotational speed of the motor with the motor controller according to a signal,including manpower output torque information, output by the pedal torque sensing mechanism; and if selecting the pure electric drive mode, regulating the output torque or the rotational speed of the motor with the motor controller according to position or angle information of the speed regulation rotation handle. The electric power-assisted bicycle has pedal power-assisted drive riding and pure electric riding, and a rider can switch a riding mode by self according to the needs and can enjoy the riding pleasure for a relatively long time.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an electric power-assisted bicycle and a driving method thereof. Background technique [0002] There are known electric assisted bicycles, that is, a power storage device such as a battery, a motor powered by the power storage device, a pedal torque sensor mechanism for detecting the pedaling force provided by the driver to the sprocket through the pedals, and the motor An auxiliary electric drive force is provided based on the output of the pedal torque sensing mechanism, enabling easy driving even when going uphill, etc. However, this pedal force auxiliary driving method cannot realize the pure electric riding mode in which the motor can drive the vehicle independently without pedal force, and it is easy to cause fatigue when riding, and it is impossible to enjoy the fun of riding for a long time; There are electric mopeds, and there are many wiring harnesses between the inst...
