Downhill automatic deceleration control device and method for electric scooter

Abstract

The invention relates to a downhill automatic deceleration control device and method for electric scooter, wherein the deceleration control device mainly comprises a microprocessor, a motor drive circuit and a feedback detection circuit, the microprocessor receives the switch opening data and controls the responding driving voltage and driving current generated by the motor drive circuit, when the motor works according to the driving voltage and driving current, the microprocessor timely monitors the state of voltage and current by the feedback detection circuit; when the microprocessor determines the electric vehicle is in downhill according to the state of voltage and current, the occupation of the pulse width modulation signal will be reduced, so that the motor current is reduced, thereby the speed of the motor is reduced, the electric car slows downhill, and is protected from the accident during the downhill.

Description

technical field [0001] The invention relates to a brake control device for an electric scooter, in particular to a downhill automatic deceleration control device that can determine whether the electric scooter is in a downhill state and automatically slow down the speed of the electric scooter when going downhill. Background technique [0002] Electric scooters have been launched on the market for many years. Its original design is to provide a simple means of transportation for the elderly or people with disabilities, so as to reduce the physical burden of such people, such as getting older or having accidents Injury, the human knee joint may not be able to withstand long-term walking due to degeneration or injury. In order to avoid further deterioration of the condition due to excessive exercise, it is necessary to appropriately reduce its activity level, so this electric walking replacement tool was developed. [0003] The power source of an electric scooter is different ...

AI Technical Summary

Problems solved by technology

[0004] Since the existing electric scooter lacks any deceleration protection mechanism when going downhill, the driver is prone to panic or even overturn due to excessive speed. The main purpose of the present invention is to provide an automatic deceleration control for electric scooter downhill The device, when it is judged that the electric scooter is going downhill, automatically reduces the current applied to the motor to slow down the running speed, thereby reducing the downhill speed of the electric scooter
