Fig. 1 is a flowchart illustrating a steering wheel abnormality processing method according to a first embodiment. As shown in fig. 1, a steering wheel exception handling method provided in an embodiment of the present invention includes:
step 201: judging whether the steering wheel is operated abnormally or not according to the number of hands on the steering wheel and the rotation information of the steering wheel;
step 202: if so, acquiring a vehicle running state;
step 203: and executing corresponding protection operation according to the vehicle running state.
In this embodiment, step 201 determines whether the steering wheel is operated abnormally according to the number of hands on the steering wheel and the rotation information of the steering wheel. Firstly, whether the number of hands on the steering wheel is larger than a preset number and the duration time exceeds a preset duration is judged, the number of hands on the steering wheel can be acquired in real time through a pressure sensor on the steering wheel or a video image above the steering wheel, and when the number of hands is larger than two and exceeds 2 seconds, judgment on rotation data of the steering wheel is triggered. The rotation sensor on the steering wheel further confirms that the behavior of robbing the steering wheel appears when just frequent rotation by a wide margin, specifically, judge whether the rotation amplitude of steering wheel is greater than the rotation frequency of presetting amplitude and steering wheel and is greater than preset frequency, the value range of presetting amplitude can be between 90 degrees to 360 degrees, it can record in the minute exceeds preset amplitude rotation number of times to preset frequency, when the number of times is greater than 3 ~ 5 times, judge that the steering wheel operates unusually, confirm that the behavior of robbing the steering wheel appears. And if the data in the judging process do not accord with the preset parameters, judging that the steering wheel operation is not abnormal. Of course, in other embodiments, parameters such as the preset number, the preset duration, the preset amplitude, the switching-to frequency and the like that appear in the present application may also be adjusted according to actual situations, which is not limited in the present application. This application catches the steering wheel operation unusually through the quantity change and the length of time of discerning the staff on the steering wheel, confirms whether robbing the steering wheel action and take place through further judging steering wheel pivoted range and frequency, avoids the driving action of wrong intervention driver, has improved the rate of accuracy of judging steering wheel unusual operation.
After the occurrence of the steering wheel robbery phenomenon is confirmed, the driving state of the vehicle needs to be acquired in time. In this embodiment, in step 202, the vehicle driving state includes at least one of vehicle head direction information, vehicle speed information, front obstacle information, and front road information. The automobile head direction information acquired by the automobile head direction sensor comprises information such as automobile head direction change and change amplitude, can be used for assisting in confirming the condition of robbing a steering wheel, and can be used for reducing accident occurrence probability and severity degree by assisting in adjusting the automobile head direction subsequently. And the accident probability can be reduced by judging the obstacles and the distance in front of the vehicle through radar identification and image identification and selecting corresponding measures of emergency braking or auxiliary braking by combining vehicle speed information. In addition, the information of the road in front is collected, and when the road in front is a sharp turn, a downhill or a densely congested road section, the information is timely reminded to avoid so as to reduce the damage degree of people and vehicles.
In this embodiment, step 203 executes a corresponding protection operation according to the vehicle running state. When the change amplitude of the direction of the vehicle head is larger than the preset change amplitude and the traveling track of the vehicle deviates, a voice alarm is given out, and passengers are reminded to keep cool and stop robbing the steering wheel in a vehicle voice and alarm sound mode. Meanwhile, the steering wheel can assist in adjusting the rotation direction and amplitude of the steering wheel to return the direction of the vehicle head, so that the vehicle can keep running on a preset road.
And when the obstacle in front of the vehicle is detected, starting braking measures for the vehicle according to the information of the obstacle in front. When the vehicle is more than the first distance and less than the second distance from the obstacle in front of the vehicle, the auxiliary brake is started to reduce the vehicle speed, and when the vehicle is less than or equal to the first distance from the obstacle in front of the vehicle, the emergency brake is started to brake the vehicle. In a conventional road section, the sum of the first distance and the second distance is set to be 10 meters and 20 meters, when the vehicle is driven in special environments such as downhill, sharp turn, wet and slippery road, highway and the like, the time required for braking the vehicle is longer, and the first distance and the second distance can be properly prolonged to ensure the safety of people and vehicles.
In one embodiment, when the steering wheel operation is judged to be abnormal, follow-up treatment measures are performed on the vehicle according to preset indexes, wherein the preset indexes comprise at least one of vehicle type, vehicle damage conditions and vehicle positions. When the vehicle robbed of the steering wheel is a public transport means, the vehicle contacts an operation company to which the vehicle belongs and gives an alarm, and simultaneously dials a telephone of the public transport company and an alarm telephone to provide vehicle position information. When a traffic accident has occurred, the insurance company and the traffic police will be contacted. When the damage degree of the vehicle is serious, if the safety airbag of the vehicle pops up, casualties possibly exist, medical rescue needs to be contacted according to the position of the vehicle, and if the position of the vehicle is in a remote area, medical rescue of the helicopter is contacted according to the situation.
As shown in FIG. 2, the steering wheel abnormality processing can be realized through four modules, namely a discovery module, a judgment module, a processing module and a recovery module.
Specifically, the steering wheel is provided with a human body recognition module and a rotation sensor. The method comprises the steps of firstly judging the number of hands simultaneously existing on a steering wheel, and when the number of hands on the steering wheel exceeds two and the duration time exceeds 2 seconds, considering that a steering wheel robbing event possibly occurs. And continuously receiving the data of the rotation sensor on the steering wheel, and further confirming that a robbing event occurs and triggering the judgment module when the steering wheel has large and frequent rotation amplitude. And a steering wheel assisting system in the processing module assists a driver to adjust the steering wheel to turn back and forth in the direction of the head of the vehicle.
In the judging module, acquire locomotive direction sensor data, when the locomotive direction turns by a wide margin and the locomotive direction will break away from the lane, processing module carries out corresponding processing measure, sends voice prompt and alarm sound through sound system, reminds driver and passenger to grab the steering wheel and is extremely dangerous action to probably offend the law, must stop at once. Then, the obstacle in the front of the vehicle is identified by using radar identification or image identification and the like, if the obstacle or pedestrian is found to be present within 20 meters, the vehicle is judged to be in a dangerous emergency state, and the processing module assists a driver to brake and slow down the vehicle. If a barrier or a pedestrian is found within 10 meters, a traffic accident is about to occur, the condition that the traffic accident is dangerous is judged, emergency braking is needed, the processing module brakes the vehicle and automatically turns on double flashes to warn. In addition, the vehicle damage degree can be judged through a vehicle damage condition judging system, and the occurrence place of the vehicle traffic accident can be determined through a GPS.
In the back module, if the vehicle robbed of the steering wheel is a bus, the bus company and the 110 are automatically informed to alarm. If the vehicle is damaged by collision, the insurance company and the traffic police are automatically informed. If the vehicle is seriously damaged and the air bag is popped up, the nearby medical rescue is informed additionally. If the vehicle is located in a remote area, the helicopter may be selected to be notified of medical assistance.
The steering wheel abnormality processing method is applied to a vehicle, and comprises the following steps: judging whether the steering wheel is operated abnormally or not according to the number of hands on the steering wheel and the rotation information of the steering wheel; if so, acquiring a vehicle running state; and executing corresponding protection operation according to the vehicle running state.

In practical implementation, two rows of laser distance sensors are arranged at the periphery of the driver seat and at the middle position of other seats, and are arranged at the top or the bottom of the vehicle. When having the passenger to disturb the driver in the driving process, its health can shelter from laser sensor, and the sensor can detect the distance and change, if be close to the passenger one row detect the distance change earlier, detect the distance change after being close to the driver's one row of sensor, then can judge someone or object and be being close to the driver, can regard this moment the driver to be disturbed, and the car machine system can send the warning according to this signal, and then begins to judge whether the steering wheel operates unusually. The intelligent system of the vehicle machine is combined with the laser distance sensor, and the vehicle machine system sends out alarm sound or warning sentences after obtaining the interference signal, so that passengers can notice that the behaviors of the passengers endanger the driving safety. The embodiment does not need to physically isolate the driver from the passenger, only sends out the warning prompt information after detecting the intrusion behavior of the passenger to the driving space, and enables the driver and the passenger to realize the dangerous behavior, does not influence the appearance of the interior trim of the bus and the sight line of the driver, and is suitable for various buses, buses and cars in the driving process, and the driver interference behavior of the passenger to the driver is prevented.
As shown in figure 3, A and B are two rows of laser distance sensors which are arranged on the top of the vehicle and downwards shoot to the bottom of the vehicle. When a person or an object moves from the auxiliary driver or the rear seat to the main driver and passes through the A and B sensors, the two sensors can detect that the distance from the roof to the bottom of the vehicle is changed. When the distance from the sensor B to the sensor A passes through the sensor B, the two sensors detect different distance change sequences, the sensor B detects the distance first and the sensor A detects the distance later, the vehicle machine system can judge whether the driver is interfered or not through the received distance change time sequence of the two sensors, and the vehicle machine system sends out warning prompt tone after judging that the interference occurs. The laser distance sensor is replaced by other distance sensors and can also be replaced by video detection, the driver and passengers do not need to be physically isolated, the internal appearance of a cab is not changed, the interference behavior is identified through the distance change and the response time sequence detected by the distance sensor, and the vehicle-mounted machine system sends out an alarm and warning voice through the identified interference signal to prevent the interference behavior from continuing.
