Embodiment 1

[0079] like figure 1 and figure 2 As shown, the electric vehicle power acceleration control system of the present application includes a motor 1, a gearbox 2, a handlebar 3 and a P gear switch 4; the motor 1 includes a motor speed sensor and a controller.

[0080] The motor speed sensor signal is output to the controller, and the controller constantly detects the motor speed. When the motor 1 speed is lower than 2500 rpm, the controller outputs an alarm to prompt the driver to switch to the mechanical gear low gear;

[0081] Preferably, the structure of the motor 1 is a magnetic steel embedded motor, which is more suitable for field weakening control, has the characteristics of large torque, high magnetic field strength, sustainable high temperature operation, and ensures stable power output of the system;

[0082] Preferably, a gyroscope is positioned inside the controller, and the controller can measure the slope when the vehicle is climbing, accurately output the control ...

Embodiment 2

[0095] In order to further reduce the probability of electric vehicle brake failure and improve the reliability of the electric vehicle; the embodiment of the present application adds an auxiliary brake assembly 100 on the basis of the above-mentioned embodiment, and the auxiliary brake assembly 100 is used in conjunction with a mechanical brake to reduce brake failure. probability.

[0096] Specifically: the electric vehicle power acceleration control system further includes an auxiliary brake assembly 100;

[0097] The auxiliary brake assembly 100 is as follows image 3 and Figure 5 As shown, including annular brake plate 110 and auxiliary brake module 120;

[0098] like Figure 5 and Image 6 As shown, the main body of the annular brake plate 110 is annular, fixed on the wheel of the vehicle, and rotates synchronously with the wheel of the vehicle. The braking module 120 cooperates to increase the braking effect;

[0099] The auxiliary brake module 120 is as follows ...

Embodiment 3

[0117] In order to further improve the practicability of the present application and the reliability of the electric vehicle, the embodiment of the present application adds an auxiliary outrigger assembly 400 on the basis of the above-mentioned embodiment; when the vehicle is on a slope, the controller controls the auxiliary outrigger assembly 400 Running to avoid vehicle slippage;

[0118] further, as Figure 4 , Figure 15 and Figure 16 As shown, the auxiliary outrigger assembly 400 is positioned at the bottom of the vehicle frame 5, and includes an outrigger body 410, an outrigger positioning assembly 420 and an outrigger driving assembly 430; the outrigger positioning assembly 420 serves as a fixed support The function of the leg main body 410; the outrigger driving assembly 430 is used to drive the outrigger main body 410 to run.

[0119] preferably, as Figure 15 As shown, the main body 410 of the outrigger is a telescopic outrigger 411,

[0120] The outrigger posi...

Abstract

The application discloses a power acceleration control system for an electric vehicle, including a motor, a motor speed sensor, a controller, a gearbox, a handle and a P-speed switch; the motor speed sensor signal is output to the controller, and the controller The motor speed is detected from time to time. When the motor speed is lower than 2500 rpm, the controller will output an alarm to prompt the driver to switch to a low mechanical gear; The P-gear signal is output to the controller, and the controller applies reverse resistance to the motor to assist the mechanical brake to smoothly pass through the steep slope section; it solves the high failure rate of the motor caused by the slope in the prior art when the electric vehicle is used in the mountainous area, which is easy to occur. The technical problems of brake failure and poor reliability of electric vehicles; the technical effects of low motor failure rate, reliable braking and high safety when electric vehicles are used in mountainous areas are realized.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a power acceleration control system for an electric vehicle. Background technique [0002] At present, under the trend of the era of vigorously developing new energy, electric vehicles are deeply loved by ordinary people in the plain areas of China. However, in mountainous areas, due to the high failure rate and low reliability of the core components of electric vehicles, the use performance is greatly reduced, which greatly affects the promotion and use in mountainous areas. [0003] The load (traction force) of an electric vehicle is the sum of rolling resistance, slope resistance, acceleration resistance and air resistance; the difference between the load that an electric vehicle needs to carry in the plain and the mountainous area is that the slope resistance is different, and the slope resistance in the mountainous area is a variable; is 10° to 30°, the variab...
