An electric vehicle that can prompt the speed control handle to turn the twist angle close to the power start control angle

Abstract

The invention belongs to the technical field of electric vehicles, and in particular relates to an electric vehicle capable of prompting that the torsion angle of a speed regulating handle is close to the power start control angle. The present invention solves the problems of bad start control and poor control of acceleration after braking in the existing electric vehicles. The present invention adopts related electronic technology on the electric vehicle to send a prompt signal when the twist angle of the speed control handle is close to the power start control angle. This enables smooth and timely acceleration when driving an electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an electric vehicle capable of prompting that the torsion angle of a speed regulating handle is close to the power starting control angle. Background technique [0002] The speed regulation of the electric vehicle relies on twisting the speed regulation handle to adjust the speed. The so-called speed regulation is essentially to adjust the output power (power) of the electric vehicle motor. The larger the twist angle of the speed regulation handle (hereinafter referred to as the torsion angle) , the greater the output power of the motor, when the manufacturer designs the electric vehicle, in order to avoid the electric vehicle’s false serial movement when the electric vehicle is stationary, the speed control handle is designed with a larger torsion angle at the beginning of the speed control without power output of the motor , when the speed control handle i...

AI Technical Summary

Problems solved by technology

[0003] However, it is precisely because of the existence of the no-power angle that the driver cannot know where the power-on control angle is, thus causing many problems

For example, when an electric vehicle starts, the driver will often turn the speed control handle at a faster speed so as to quickly pass through the no-power angle to reach the power-on control angle, but since the driver does not know where the power-on control angle is, it is impossible to When it is close to the power start control angle, stop and then slowly turn the speed control handle to start smoothly, but it is easy to exceed the power start control angle at once, causing the electric car to start with too much power, and the electric car suddenly Acceleration (compared to motorcycles with clutches and noisy engines, this is a defect of electric vehicles)

For another example, during the driving process, when the electric vehicle needs to accelerate after coasting or after braking (at this time, the speed control handle has been turned back to the no-power angle area), since the driver does not know the power starting control angle There, when turning the speed control handle to accelerate, it is easy to exceed the power starting control angle at once, causing the electric vehicle to accelerate too much, and the electric vehicle accelerates suddenly, which is likely to cause accidents

In order to avoid the sudden acceleration of the electric vehicle, some drivers slowly twist the speed control handle, so that the electric vehicle slowly enters the power starting control point, but such an operation method will cause the speed control handle to pass through the non-power angle for too long. not getting off the ground as quickly as possible or accelerating in time
