AI Technical Summary

Technical Problem

Existing electric tricycles using mechanical differentials have high maintenance costs and generate a lot of noise. Furthermore, electric differential technology is not accurate enough in judging the vehicle's driving status, which affects the vehicle's passability.

Method used

It adopts a dual-hub motor independent drive scheme, combined with a six-axis attitude sensing unit and a vehicle control unit, and independently adjusts the torque and speed of the drive wheels through the Ackermann steering geometry principle, replacing the traditional mechanical differential and improving the accuracy of driving status judgment.

Benefits of technology

Reduce maintenance costs, eliminate noise, improve vehicle stability and passability, and achieve vehicle lightweighting and maintenance-free operation.
