What are the benefits of using vector control algorithms in electric tricycles for the elderly?

1. Improve driving performance
1.1 Accurately control torque output
The application of vector control algorithms in electric tricycles for the elderly can achieve accurate control of motor torque. Under traditional control methods, the motor torque output is affected by many factors and fluctuates greatly, which can easily lead to vehicle start-up frustration and unstable acceleration. The vector control algorithm decomposes the stator current of the AC motor into the excitation current that generates the magnetic field and the torque current that generates the torque, and controls them separately, so that the motor can output stable and accurate torque under different working conditions.
In the starting stage, the algorithm can quickly and accurately distribute enough torque to make the vehicle start smoothly and avoid vehicle shaking or loss of control caused by insufficient or excessive torque. According to statistics, the starting time of electric tricycles using vector control algorithms can be shortened by about 20%, and the shaking amplitude of the vehicle at the start is reduced by more than 30%.
During the climbing process, the algorithm can adjust the torque output in real time according to the slope and vehicle load to ensure that the vehicle has enough power to climb the slope and the wheels will not slip due to excessive torque. For example, at a 15-degree slope, the vehicle’s climbing ability can be improved by about 25%, and the probability of wheel slippage when climbing is reduced to less than 5%.
During acceleration and deceleration, the vector control algorithm can smoothly adjust the torque, reduce the vehicle’s sense of frustration, and provide a more comfortable driving experience for elderly drivers. During acceleration, the vehicle’s acceleration fluctuation range can be controlled within ±0.1m/s²; during deceleration, the vehicle’s deceleration fluctuation range can also be controlled within ±0.1m/s², effectively reducing the discomfort during driving.

2. Enhanced safety performance
2.1 Stabilize vehicle driving state
The vector control algorithm is used in electric three-wheeled scooters for the elderly, and has a significant effect on stabilizing the vehicle’s driving state.
Prevent rollover: When the vehicle turns, the vector control algorithm can accurately control the motor torque output to keep the vehicle at a stable driving speed and power distribution. For example, when driving on a curve with a radius of 10 meters, the body roll angle of the electric three-wheeled scooter using this algorithm can be reduced by about 15%, effectively reducing the risk of vehicle rollover.
Avoid loss of control: In complex road conditions, such as slippery or uneven roads, the vector control algorithm can adjust the motor speed and torque in real time according to the vehicle’s driving state and road conditions to ensure stable driving of the vehicle. According to statistics, the probability of vehicle loss of control can be reduced by about 35% when driving on slippery roads, providing a safer driving environment for elderly drivers.

3. Improve energy efficiency
3.1 Optimize motor operation efficiency
The application of vector control algorithm in electric three-wheeled scooters for the elderly can significantly improve the operation efficiency of the motor, thereby improving the energy utilization efficiency of the vehicle.
Accurately control current: The vector control algorithm accurately controls the excitation current and torque current of the motor, so that the motor can maintain the best operating state under different working conditions. When driving at low speed, the efficiency of the motor can be improved by about 10%; when driving at medium and high speeds, the efficiency can be improved by more than 15%. This precise control reduces the reactive power loss of the motor and improves the efficiency of converting electrical energy into mechanical energy.
Reduce energy consumption: Due to the improvement of motor operation efficiency, the energy consumption of the vehicle during driving is significantly reduced. According to statistics, the energy consumption of electric three-wheeled scooters using vector control algorithms can be reduced by about 20% per 100 kilometers. This means that the vehicle’s cruising range can be increased, the number of charging times and charging time are reduced, and a more convenient user experience is provided for elderly drivers.
Extend battery life: The reduction in energy consumption not only reduces the frequency of battery use, but also reduces the depth of battery charge and discharge, thereby extending the battery life. According to experimental data, the battery life of vehicles using vector control algorithms can be extended by about 25%, reducing the cost of battery replacement and improving the economy of the vehicle.
Dynamic power adjustment: The vector control algorithm can dynamically adjust the output power of the motor according to the actual needs of the vehicle. When the vehicle is unloaded or lightly loaded, the motor output power is automatically reduced to reduce unnecessary energy consumption; when the vehicle load increases, the motor can quickly adjust the output power to meet the power needs of the vehicle. This intelligent adjustment function enables the motor to always work in the high-efficiency range, further improving energy utilization efficiency.
Reduce mechanical wear: Precise control of the motor torque output reduces the frustration of the vehicle during starting, acceleration and deceleration, and reduces the mechanical impact of the transmission system. This not only improves driving comfort, but also reduces the wear of mechanical components and reduces the maintenance cost of the vehicle. According to statistics, the wear of the vehicle transmission system using the vector control algorithm is reduced by about 30%, which extends the service life of the vehicle.

4. Improve the riding experience
4.1 Smooth acceleration and deceleration
The application of the vector control algorithm in the electric three-wheeled scooter for the elderly has greatly improved the riding experience, especially in terms of smoothness during acceleration and deceleration.
Acceleration process: Since the vector control algorithm can accurately control the motor torque output, the vehicle’s power output is more linear and smooth during acceleration. Under the traditional control method, there may be a sudden forward rush when the vehicle accelerates, causing discomfort to elderly passengers. After adopting the vector control algorithm, the acceleration fluctuation range of the vehicle during acceleration can be controlled within ±0.1m/s². This smooth acceleration process reduces the forward and backward tilt of the passenger’s body, making the riding experience more comfortable. For example, in the process of accelerating from static to 15km/h, the forward and backward shaking of the passenger’s body in the vehicle using the vector control algorithm can be reduced by about 40%.
Deceleration process: During deceleration, the vector control algorithm can also achieve smooth deceleration. During the deceleration process, the deceleration fluctuation range can also be controlled within ±0.1m/s², avoiding the discomfort caused by the excessive forward leaning of the passenger body due to sudden deceleration. This smooth deceleration process not only improves the ride comfort, but also reduces the impact force when the vehicle brakes and reduces the wear of the vehicle’s braking system. According to statistics, the wear of the vehicle’s braking system using the vector control algorithm is reduced by about 20%, extending the service life of the braking system.

5. Simplify the operation process

5.1 Adaptive driving needs
The application of the vector control algorithm in the elderly electric three-wheeled scooter can automatically adjust the vehicle’s driving state according to the driver’s operating habits and actual driving needs, greatly simplifying the operation process.
Automatically adjust the power output: The algorithm can automatically adjust the torque output of the motor according to the driver’s accelerator pedal depth and change rate, making the vehicle’s power response more sensitive and accurate. For example, when the driver lightly steps on the accelerator pedal, the vehicle can accelerate smoothly; when the driver quickly steps on the accelerator pedal, the vehicle can quickly provide sufficient power. This automatic adjustment function reduces the number of times the driver frequently adjusts the accelerator pedal and reduces the complexity of driving operations.
Intelligent recognition of driving mode: The vector control algorithm can collect vehicle driving data such as vehicle speed, acceleration, steering angle, etc. through sensors to intelligently recognize the driver’s driving mode. For example, when the driver frequently starts and stops on urban roads, the algorithm will automatically switch to economic mode, reduce the power output of the motor, and reduce energy consumption; when the driver is driving on open roads, the algorithm will automatically switch to sports mode, increase the power output of the motor, and provide stronger power. This intelligent recognition function enables the vehicle to automatically adapt to different driving scenarios without the driver having to manually switch driving modes.
Simplified braking operation: During braking, the vector control algorithm can automatically adjust the regenerative braking power of the motor according to the vehicle speed and the pedaling force of the brake pedal. When the driver lightly steps on the brake pedal, the vehicle can decelerate smoothly and the motor can recover some energy; when the driver steps on the brake pedal heavily, the vehicle can decelerate quickly and the motor can provide greater regenerative braking power. This automatic adjustment function reduces the driver’s frequent operation of the brake pedal and improves the safety and comfort of braking.
Adapt to the needs of different drivers: Due to the differences in the physical conditions and driving habits of elderly drivers, the vector control algorithm can be personalized according to the needs of different drivers. For example, for drivers with slower reactions, the algorithm can appropriately extend the acceleration and deceleration time of the vehicle to make the driving process smoother; for drivers who like to start quickly, the algorithm can appropriately increase the initial acceleration of the vehicle. This personalized adjustment function enables the vehicle to adapt to the needs of different drivers and improves the comfort and convenience of driving.
