Abstract

The invention relates to an emergency steering control method and device and computer equipment. The method comprises the steps that in the vehicle running process, the working state of a vehicle steering control system and the running speed of a vehicle are monitored in real time; in the vehicle driving process, front road surface information from the automatic driving system is received in real time; when the steering control system has a steering fault, the running speed of the vehicle is obtained in real time; on the basis of the running speed of the vehicle, a braking system and / or a driving system are selected to achieve vehicle emergency steering, and the working state of a steering system is monitored in real time to ensure that the working condition of the vehicle is known in real time; if the vehicle steering system breaks down, it is guaranteed that the vehicle can steer smoothly and stably at any running speed on the premise that additional mechanical equipment is not added, and therefore safe running of the vehicle is further guaranteed.

Description

technical field

[0001] The present application relates to the technical field of vehicle driving, and in particular, to an emergency steering control method, device and computer equipment. Background technique

[0002] When the vehicle is running, the steering of the vehicle is realized by controlling the steering system of the vehicle. When the steering system of the vehicle fails, the vehicle cannot be steered, which will greatly reduce the driving safety of the vehicle.

[0003] In the prior art, in order to deal with the failure of the vehicle steering system and realize the emergency steering of the vehicle, the following methods are often used: first, by adding a mechanical control structure to manually adjust the air brake pipeline to brake and hold the inner wheels of the vehicle; brake, and at the same time increase the driving force of the outer wheels of the vehicle to reduce the turning radius of the vehicle; secondly, the emergency steering control of the vehicl...

Examples

Embodiment 1

[0043] The emergency steering control method provided by this application, such as Figure 1 to Figure 3 As shown, the emergency steering control method provided in this application is applied to a front-wheel drive, rear-wheel drive or four-wheel drive vehicle, and the method includes the following steps:

[0044] Step S1, during the running of the vehicle, monitor the working state of the vehicle steering control system and the running speed of the vehicle in real time;

[0045] Step S2, when a steering failure occurs in the steering control system, obtain the driving speed of the vehicle in real time;

[0046] Step S3, if the traveling speed of the vehicle is higher than the first threshold, the vehicle controller sends a braking command to the braking system to realize emergency steering of the vehicle; if the traveling speed of the vehicle is not higher than the first threshold If the threshold value is exceeded, the vehicle controller sends a drive command to the drive ...

Embodiment 2

[0078] An emergency steering control method, the method comprising: monitoring the working state of the vehicle steering control system and the driving speed of the vehicle in real time during the driving process of the vehicle; and obtaining the driving speed of the vehicle in real time when a steering failure occurs in the steering control system ; If the traveling speed of the vehicle is higher than the first threshold, the vehicle controller sends a braking command to the braking system to realize emergency steering of the vehicle; if the traveling speed of the vehicle is not higher than the first threshold, Then the vehicle controller sends a drive command to the drive system to implement emergency steering of the vehicle.

[0079] In one embodiment, if the driving speed of the vehicle is not higher than the first threshold, the method further includes: if the driving speed of the vehicle is not higher than the first threshold, the whole The vehicle controller sends braki...

Embodiment 3

[0091] In one embodiment, as Image 6 As shown, an emergency steering control device is provided, comprising: a monitoring acquisition unit and an emergency control unit, wherein:

[0092] Monitoring and obtaining unit, in the process of vehicle driving, the monitoring and obtaining unit is used to realize real-time monitoring of the working state of the vehicle steering system and the driving speed of the vehicle; when a steering failure occurs in the steering control system, the monitoring and obtaining unit is also used for real-time obtaining the speed of travel of the vehicle;

[0093] an emergency control unit, the emergency control unit is connected in communication with the monitoring and acquisition unit, and the emergency control unit is used to judge whether the driving speed of the vehicle is higher than a first threshold based on the driving speed of the vehicle; If the driving speed of the vehicle is higher than the first threshold, the vehicle controller sends ...
