Moped speed induction type power-assisted control method

Abstract

The invention discloses a moped speed induction type power-assisted control method which is used in the technical field of mopeds. According to the moped speed induction type power-assisted control method, based on an original speed induction type power-assisted control method, the inclined degree of the road surface is measured in real time by additionally arranging an inclined angle sensor, the output of the inclined angle sensor serves as the compensation input of a system, and thus the system has the capacity that different power-assisted output is achieved under the same speed and different road conditions, wherein the capacity is not achieved by the original speed induction type power-assisted control method; and power assistance is optimized, and experience and / or rising experience of a client are / is improved.

Description

technical field [0001] The invention relates to the technical field of electric power-assisted two-wheeled vehicles, in particular to a speed-sensing type power-assisted control method for a power-assisted vehicle. Background technique [0002] There are two main methods used in existing mopeds: one is the torque induction type, which mainly relies on the torque sensor to sense the pedaling force of the rider to control the output torque of the torque motor, and always follows the high, medium and low speeds. A certain power ratio output, the riding experience is better, but the cost is higher; the second is the speed induction type, which mainly relies on the speed sensor to sense the rider's pedaling frequency to control the output speed of the ordinary brushless speed-adjustable motor. The characteristic is that the size of the booster is positively correlated with the speed. If you increase the booster output in the uphill chronic state, you must increase the booster rat...

[0002] There are two main methods used in existing mopeds: one is the torque induction type, which mainly relies on the torque sensor to sense the pedaling force of the rider to control the output torque of the torque motor, and always follows the high, medium and low speeds. A certain power ratio output, the riding experience is better, but the cost is higher; the second is the speed induction type, which mainly relies on the speed sensor to sense the rider's pedaling frequency to control the output speed of the ordinary brushless speed-adjustable motor. The characteristic is that the size of the booster is positively correlated with the speed. If you increase the booster output in the uphill chronic state, you must increase the booster ratio setting, but this will bring a sense of forward rush when driving slowly on flat roads and stepping in the air when riding at high speed. On the contrary, it will bring a feeling of powerlessness when going uphill slowly. This method is difficult to take into account the riding experience of high, low speed and different road conditions, but because of its low cost, it is widely used in low-end mopeds
