Embodiment 1

[0036] This embodiment provides a method for an electric assist shared vehicle to assist the vehicle to go up and downhill. The electric assist shared vehicle is provided with a gyroscope, such as figure 1 shown, including steps:

[0037] S11, collecting vehicle angular velocity data through a gyroscope;

[0038] S12. Judging the uphill and downhill state of the vehicle according to the angular velocity data;

[0039] S13. If the vehicle is in an uphill state, send an electric assist command to the battery pack, and the battery pack activates the electric assist to assist the vehicle uphill.

[0040] In recent years, shared bicycles continue to appear in our lives. Shared bicycles can generally satisfy most people's driving solutions for traffic congestion through the form of rental. However, usually shared bicycles require users to pedal to generate power to drive. Some users feel that Stamping for a long time is prone to fatigue, resulting in a bad driving experience and n...

Embodiment 2

[0060] This embodiment provides a method for an electric assist shared vehicle to assist the vehicle to go up and downhill. The electric assist shared vehicle is provided with a gyroscope, such as image 3 shown, including steps:

[0061] S21, collecting vehicle angular velocity data through a gyroscope;

[0062] S22. Judging the uphill and downhill state of the vehicle according to the angular velocity data;

[0063] S23. If the vehicle is in an uphill state, send an electric assist command to the battery pack, and the battery pack activates electric assist to assist the vehicle uphill;

[0064] S24. Determine whether the angular velocity data reaches a preset maximum angular velocity, and if so, send an early warning signal to stop driving.

[0065] Different from the embodiment, this embodiment further includes step S24.

[0066] In this embodiment, by setting the maximum angular velocity value, when the gyroscope remembers that the angular velocity data exceeds the maxi...

Abstract

The invention discloses a vehicle uphill and downhill assisting method and system for an electric power assisted shared vehicle. A gyroscope is arranged on the electric power assisted shared vehicle.The vehicle uphill and downhill assisting method for the electric power assisted shared vehicle comprises the steps of S1, collecting angular velocity data of the vehicle by using the gyroscope; S2, judging uphill and downhill states of the vehicle according to the angular velocity data; and S3, if the vehicle is in the uphill state, transmitting an electric power assisting instruction to a battery pack, wherein the battery pack starts electric power to assist the vehicle to go uphills. According to the vehicle uphill and downhill assisting method for the electric power assisted shared vehicle, the angular velocity data of the vehicle is collected by using the gyroscope arranged on the electric power assisted shared vehicle; the uphill and downhill gradients can be accurately judged by using the angular velocity data measured by the gyroscope to judge the uphill and downhill states of the vehicle in the running process; when judging that the vehicle is in the uphill state, the electricpower assisting instruction is transmitted to the battery pack; and the battery pack provides intelligent electric power to the electric power assisted shared vehicle according to the instruction; and therefore, the method is more intelligent and safer, the cost is low, and the riding experience is improved for users of the electric power assisted shared vehicle.

Description

technical field [0001] The present invention relates to a shared vehicle, in particular to a method and system for assisting a vehicle to go up and downhill with an electric power-assisted shared vehicle Background technique [0002] With the continuous development of urbanization, more and more people work and live in the city. The traffic situation in the city is not optimistic, especially in the bustling areas and during the rush hour. In order to solve the short-distance travel of users It can avoid urban congestion. In recent years, shared bicycles have been vigorously promoted. Shared bicycles can generally meet the driving needs of most people in the form of leasing. However, usually shared bicycles require users to pedal to generate power to drive. It is prone to fatigue after a long time, resulting in poor driving experience. [0003] At this stage, electric power-assisted shared vehicles have gradually appeared. By providing electric power to bicycles, the fatigue...
