AI Technical Summary

Technical Problem

When a vehicle travels over uneven road surfaces, especially speed bumps or potholes, the wheel speed of the rear wheels and the motor speed of the rear-wheel drive motor fluctuate greatly, causing the rear of the vehicle to tremble or vibrate, affecting passenger comfort.

Method used

By monitoring the vehicle's driving status in real time, including vehicle speed and longitudinal acceleration of each front wheel, it determines whether the conditions for triggering the shock absorption function are met, and adjusts the energy recovery torque and shock absorption damping within a preset judgment period to reduce vehicle vibration.

Benefits of technology

Before a vehicle travels over uneven roads that may cause vibrations, the energy recovery torque and damping are adjusted in advance to reduce the speed fluctuations of the rear-wheel drive motor, thereby reducing the intensity and frequency of vibrations at the rear of the vehicle and improving passenger comfort.

Abstract

The application provides a damping method and device, electronic equipment, storage medium and vehicle; the method comprises the following steps: monitoring the current driving state of the vehicle in real time, wherein the current driving state comprises the vehicle speed and the movement of each front wheel of the vehicle; determining whether the current driving state meets the condition of triggering the damping function in the preset determination period, wherein the damping function comprises adjusting the energy recovery torque of the vehicle and the damping damping of the shock absorber; in response to determining that the condition is met, the adjustment of the energy recovery torque and the damping damping is triggered to reduce the vibration of the vehicle. It can be seen that the application not only reduces the vibration of the vehicle, but also improves the efficiency of the damping function, and avoids triggering the damping function on uneven road surfaces that do not cause vibration.
