Vehicle fault tolerance time calculation method and system, medium and electronic equipment

Abstract

The invention discloses a vehicle fault tolerance time calculation method and system, a medium and electronic equipment. The vehicle fault tolerance time calculation method comprises the following steps that a vehicle emergency steering intelligent auxiliary function is controlled to be triggered; when a vehicle accident occurs, the vehicle runs on the straightway, the initial straightway duration time from the time when a driver does not operate the vehicle to the time when the vehicle collides is obtained, and the straightway response time when the driver operates the vehicle is obtained; and obtaining straightway fault tolerance time when the vehicle emergency steering intelligent auxiliary function is triggered. The vehicle runs on the curve, the curve initial duration time from the time when a driver does not operate the vehicle to the time when the vehicle collides is obtained, and the curve response time when the driver operates the vehicle is obtained; curve fault tolerance time when the vehicle emergency steering intelligent auxiliary function is triggered is obtained; therefore, the response time for the driver to operate the vehicle when an accident occurs is determined, a certain response time can be given to the driver when a danger occurs, and the driving safety of the driver is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile communication, in particular to a method, system, medium and electronic equipment for calculating vehicle fault tolerance time. Background technique [0002] At present, the lateral control and vertical control functions of the intelligent assisted driving system of self-driving vehicles may fail or be triggered unexpectedly. If the driver does not control the vehicle in time, the vehicle will lose control, which will bring safety hazards. [0003] The fault tolerance time in the traditional sense is the time from when a system failure occurs and the vehicle does not adopt any safety mechanism until danger occurs. In order to ensure the safety of driving, when the auxiliary function fails, the function needs to be exited within the fault tolerance time, prompting the driver to take over the vehicle, and a certain amount of reaction time should be left for the driver. Therefore, the driver's re...

Problems solved by technology

[0004] In the existing technology, in order to ensure the safety of the experimenters, the tested vehicle directly driven by the experimenter may cause the vehicle to be out of control and cause the experimenter to be injured. Control the driverless car under test

However, the existing technology remotely controls the car for testing, and the fault tolerance time of the traditional braking system and steering system can be determined, but for the intelligent auxiliary system, the delay and interference of the remote control cannot be accurately calculated and deducted. takeover reaction time

Therefore, the existing method for determining the fault tolerance time does not target the relevant functions of the intelligent assistance system, and the existing method for determining the fault tolerance time is not suitable for the intelligent assistance system
