AI Technical Summary

Technical Problem

Existing technologies cannot effectively verify the reliability of a vehicle's transmission system in overcoming slip torque when the differential lock is engaged, especially in scenarios of accidental triggering.

Method used

By simulating extreme scenarios under extreme load conditions with the differential lock engaged, including full acceleration and rapid start-up and constant speed driving and continuous steering, dynamic inspection information and status results are recorded to determine the reliability of the transmission system.

Benefits of technology

It can efficiently simulate the transmission system's extreme capabilities under extreme operating conditions, determine the reliability of the transmission system in overcoming slip torque when the differential lock is engaged, and avoid structural damage to the transmission system.

Abstract

The application relates to the technical field of vehicles, in particular to a differential lock false triggering scene test method and device, a vehicle and a storage medium, the method comprises the following steps: determining that a current vehicle state meets a preset extreme load state; in a differential lock locking state, testing according to a preset extreme scene test mode; saving dynamic check information of the differential lock in the testing process and state result information of the differential lock and a vehicle transmission system after the testing; according to the application, the extreme scene test is carried out on the vehicle with the differential lock false triggering under the extreme load state, the limit capability of the vehicle transmission system when the vehicle is in the extreme scene is tested, the limit working condition possibly encountered in the use of the vehicle can be efficiently simulated, and then the reliability of the vehicle transmission system in overcoming the sliding torque under the differential lock locking state can be determined according to the dynamic check information and the state result information obtained through the testing.
