Embodiment approach 1

[0033] A signal line is connected from the controller to an uphill auxiliary switch; further, the uphill auxiliary switch includes but is not limited to a touch button switch.

[0034] The implementation process is: when the vehicle is temporarily parked on an uphill and ready to start, press the uphill auxiliary switch, and the controller will start the uphill auxiliary function after receiving the corresponding signal. Activate torque mode. Among them, the maximum starting torque mode is: no matter what the rotation range of the handlebar is, as long as the handlebar is rotated to generate a handlebar rotation signal, the motor will output at the maximum torque, so as to obtain the maximum starting power when the electric vehicle starts.

[0035] In this solution, the braking force is maintained by pinching the brake lever and turning the handle. Since it is in the maximum starting torque mode at this time, no matter how much the handle is turned, the controller only needs t...

Embodiment approach 2

[0037] A signal line is connected from the controller to an uphill auxiliary switch, and the uphill auxiliary switch includes but is not limited to a touch button switch. The implementation process is: when the vehicle is temporarily parked on an uphill and ready to start, press the uphill auxiliary switch, and the controller enters the anti-rolling mode at this time. In the anti-rolling mode, the controller short-circuits the three-phase The motor locks to generate braking force while the controller enters the maximum starting torque mode. When starting, turn the handle to make the motor output the maximum torque, the three-phase short-circuit brake is released, and the vehicle begins to climb steadily. When the vehicle's driving speed reaches 5 km / h (including but not limited to this speed), the uphill assist function is released, and the driving torque returns to the normal control mode.

[0038] Automatic parking mode: the automatic parking mode is a control method for au...

Embodiment approach 3

[0041] Install an electronic gyroscope on the controller or other parts of the electric vehicle.

[0042] The implementation process is: when the vehicle is temporarily parked on an uphill and ready to start, the electronic gyroscope detects that the vehicle angle reaches the specified range, the range is set but not limited to (5-20°), and the angle is set but not limited It is the angle between the connection line between the front and rear wheels of the vehicle and the tangent point of the ground and the horizontal plane, which changes with the slope. At this time, the controller enters the anti-rolling mode. In the anti-rolling mode, the controller short-circuits the three phases to lock the motor to generate braking force when the vehicle stops, and simultaneously the controller enters the maximum starting torque mode. When starting, turn the handle to make the motor output the maximum torque, the three-phase short-circuit brake is released, and the vehicle begins to clim...

Abstract

The invention provides a control method for uphill auxiliary and parking of an electric bicycle. The control method comprises the steps that a controller starts an uphill auxiliary function, relieves a braking power off function and enters a maximum starting torque mode; under the maximum starting torque mode, once a rotary handle rotating signal is obtained by the controller, the controller controls a motor to output the maximum torque regardless of the magnitude of the strength or the amplitude of the rotary handle rotating signal so that the electric bicycle can obtain the maximum starting power during starting; and when the controller detects that the motor reaches the specified rotating speed, the uphill auxiliary function is relieved, and the braking power off function is recovered. According to the control method for uphill auxiliary and parking of the electric bicycle, the braking force and the maximum starting torque of the electric bicycle can be kept at the same time during parking and starting of the electric bicycle in the uphill process, so that the situation that the electric bicycle slides down from a slope is prevented.

Description

technical field [0001] The invention belongs to the field of electric bicycle control systems, and in particular relates to a control method for uphill assistance and parking. Background technique [0002] Present electric bicycle starts after stopping halfway uphill, runs into steep slope, because vehicle power is insufficient, the phenomenon of rolling backward can take place. Contents of the invention [0003] In view of this, the present invention aims to propose a controller control method that enables the vehicle to simultaneously maintain the braking force and the maximum starting torque to prevent the vehicle from slipping when the electric bicycle is parked and started during the uphill process. [0004] In the description of the present invention, it should be understood that the electric bicycle referred to herein is not limited to two-wheeled, but also three-wheeled or four-wheeled, and is not limited to the use of people, but also the use of goods. . In addi...
