Embodiment 1

[0029] This embodiment introduces a safety intervention system when the steering wheel of a vehicle is out of control. The vehicle adopts a steer-by-wire system. The safety intervention system includes a driver monitoring module, a passenger monitoring module, a voice warning module, a steering wheel lock control module, and an environment perception module, safe driving module and one-button recovery module, such as figure 1 As shown, the above modules communicate through the CAN bus.

[0030] The driver monitoring module usually uses a camera to recognize the driver's face and behavior characteristics by collecting the driver's image in real time, and judge whether the driver has lost consciousness. If so, it will trigger the voice warning module and the steering wheel lock control module , if it is detected that the driver is fatigued or inattentive, then this situation only needs a voice reminder, such as "please keep driving focused and concentrate", without triggering th...

Embodiment 2

[0040] This embodiment introduces the method of using the security intervention system in Embodiment 1 to perform security intervention, and its process is as follows figure 2 shown.

[0041] Step 1. Collect information: During the driving process of the vehicle, the driver monitoring module monitors the driver's face and behavior characteristics, and judges whether the driver is fatigued, bows his head, or lacks concentration. If so, perform step 2. If If it is detected that the driver loses consciousness, then perform steps 2 and 3; at the same time, the passenger monitoring module collects images and sounds of passengers close to the driver to determine whether the passenger insults or threatens the driver, and if so, executes Step 2, if it is detected that the passenger further snatches the steering wheel or has physical contact with the driver, then go to step 3; the infrared sensing module monitors whether any passenger's body has crossed the driver's cab guardrail, and...

Abstract

The invention provides a safety intervention system and method when vehicle steering wheel losing control. The safety intervention system comprises a driver monitoring module, a passenger monitoring module, a voice warning module, a steering wheel locking control module, an environment sensing module, a safety driving module, and a one-key recovery module, which are communicated with each other through CAN buses. Whether the possibility of endangering the driving safety of the vehicle exists or not can be determined by detecting real-time states of a driver and passengers, the voice warning and the steering wheel locking are adopted, the steering wheel is locked by a steering wheel locking control module, and signals between a lower steering motor and an upper motor of a steer-by-wire system are cut off, and then a safe driving module is triggered, the authority of the driver is taken over, and automatic driving and safe parking can be realized.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a safety intervention system and method when the steering wheel of a vehicle is out of control. Background technique [0002] Cars are one of the main means of transportation for people to travel. While bringing great convenience to people, the rate of vehicle accidents has also increased. Especially the safety of buses is related to the lives of more people and the happiness of many families. On the one hand, the driver must abide by traffic laws and travel in a civilized manner during the driving behavior; The situation has aroused the attention of the whole society. In order to avoid the occurrence of similar incidents, when the bus steering wheel loses the driver's control, safety intervention is required. [0003] At present, the steering wheel needs to intervene in the control mostly because the vehicle has a tire burst during driving and a locking intervention...
