AI Technical Summary

Technical Problem

The wireless transmission stability of existing drive-by-wire chassis devices is weaker than that of wired transmission, and wireless transmission is easily interfered with in the event of a fault, affecting the timeliness of vehicle control.

Method used

An automatic switching mechanism for main and auxiliary connectors was designed. It uses a spring-driven push block to achieve seamless switching, ensuring that the auxiliary cable can quickly take over when the main connector falls off. Combined with a ventilation component, it uses vibration to drive a knocking rod to remove dust and ensure heat dissipation. The warning component automatically alerts to fault conditions.

Benefits of technology

It achieves power and signal continuity for the drive-by-wire module, avoids the instability of wireless transmission, improves the reliability and safety of vehicle operation under fault conditions, reduces maintenance frequency, and enhances the system's environmental adaptability and maintainability.

Abstract

The application discloses a drive-by-wire chassis for automatic driving of a new energy vehicle, and belongs to the drive-by-wire chassis field.The drive-by-wire chassis comprises a vehicle frame, an installation plate is fixedly connected to the inner side of the vehicle frame, a protection box is fixedly connected to the upper end of the installation plate, and a drive-by-wire combination module is arranged in the protection box.The rear end of the protection box is fixedly connected with a fixed seat A and a fixed seat B.The application realizes seamless automatic switching of main and auxiliary cables.When the main connector is accidentally dropped, spring A drives the push block to reset, and converts horizontal movement into a longitudinal docking action of the auxiliary connector through a chute mechanism, so that the auxiliary cable quickly takes over the work, guarantees the continuity of power supply or signals of the drive-by-wire combination module, and completes switching in an instant when the main connection fails, ensures the basic control function of the automatic driving vehicle under sudden failure, and avoids the instability of wireless transmission and provides protection for wired transmission.
