AI Technical Summary

Technical Problem

In the existing technology, the switching of the vehicle's active short-circuit mode is prone to failure in complex and ever-changing environments, posing a significant safety hazard and failing to effectively guarantee stable limp driving at high speeds or prevent secondary damage.

Method used

By obtaining the maximum allowable recharge power of the power battery and the default limp speed, the maximum allowable switching speed and switching threshold are determined. The vehicle is controlled to actively short-circuit switch when there is an electric drive failure, and the switching of ASC/FW mode is flexibly adjusted to avoid failures caused by fixed thresholds.

Benefits of technology

It improves vehicle safety in the event of electric drive failure, avoids battery failure and irreversible capacity loss caused by uncontrollable recharge current, and ensures the vehicle's stable limp-riding capability in failure conditions.

Abstract

Provided in the present disclosure is an active short circuit switching control method for a vehicle. The method comprises: acquiring the current maximum allowable recharge power of a traction battery, and a default limp-home speed; on the basis of the maximum allowable recharge power, determining the maximum allowable switching speed; on the basis of the maximum allowable switching speed and the default limp-home speed, determining a switching threshold value; and when a vehicle needs to perform active short circuit switching, on the basis of the switching threshold value, controlling the vehicle to perform active short circuit switching.
