What should I do if the steering wheel is out of control while the car is moving?

When the car suddenly loses control in the direction of driving, the driver should use the service brake to stop, slowly press the brake pedal, and avoid emergency braking, so as to avoid the vehicle skidding and causing accidents. In addition, while pulling the service brake and parking brake, it is also necessary to turn the steering wheel in the direction of natural obstacles as much as possible, and use the roadside obstacles to stop and avoid danger.

<> Traffic Safety Micro Classroom Is the steering wheel out of control? If there is a sudden turnaround or immobility during driving, you should immediately press the brake pedal to control the speed. If the vehicle is driving in a curve and suddenly loses steering, the vehicle will often rush off the road and crash or overturn.

At this time, you should brake urgently, hold the steering wheel at the same time, lean back, close to the back of the seat, and let the car roll. Road safety has even risen to an important indicator of endangering the health of residents, in recent years, global road traffic accidents have occurred frequently, has caused more than 1.3 million deaths, more than 500,000 injuries, at the same time, road safety accidents have become the primary cause of personnel in China. Most traffic accidents are caused by people's lack of safety awareness and self-protection awareness.

If the vehicle and the road are allowed to go straight all the way, do not take emergency braking, because when the car is driving at high speed, emergency braking is easy to cause rollover, at this time, you should immediately lift the accelerator, rush to slow down, or even tighten the handbrake, when the speed slows down, gently press the brake pedal, and the vehicle slowly stops. Don't think that the accident is far away from you and be lucky, as long as you drive on the road, the danger will always be with you, no one knows what will happen in the next second, so from the moment you touch the car, you should pay attention to the traffic rules and learn to save yourself, only in this way can you minimize the loss when the accident occurs, otherwise you will regret it.

Do a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

In the process of driving, if the steering wheel suddenly loses control, you should pull over as soon as possible, otherwise it is easy to be dangerous, and then check the fault yourself or find a maintenance personnel to check.

At this time, you should stay calm, you should slowly release the throttle, then turn to a low gear, then gently pull the handbrake, and when the speed decreases, stop on the side of the road.

You should slowly slow down your speed, brake first, pay attention to the car coming from behind, try to stop the car, pull over the car, and then call for help**.

The steering wheel is difficult to control during driving, and it can manifest itself in a variety of phenomena.

If it feels hard when you turn the steering wheel. The reason could be: incorrect wheel alignment.

Insufficient tire pressure. The steering transmission mechanism is deformed, worn, and the ball pin is too tight. The oil quantity of the steering gear is insufficient, the meshing clearance of the steering gear meshing pair is too small, and the bearing is preloaded or damaged.

Safety steering column deformation. The front single coil spring is broken or the body and frame are deformed. The mating clearance between the kingpin and the bushing is too small or the pressure bearing is damaged.

The clearance of the ball joint in the horizontal and straight rod sections is too small. All moving parts are short of oil. Due to the many factors that contribute to steering failure, fault diagnosis should be carried out first, and then the location of the component should be further determined.

The specific workaround is as follows:

(1) Remove the steering arm and turn the steering wheel, if you feel that the bearing is heavy, adjust the tightness and transmission engagement clearance. If there is uneven tightness or stagnation, the steering shaft should be removed, the transmission pair and bearing should be checked for damage, and the steering shaft and head should be repaired or replaced if necessary.

2) Turn the steering wheel, if you feel relieved, the transmission mechanism is faulty, you should jack up the front axle and pull the left and right front wheels with your hands. If it is too tight, check that the knuckle kingpin and bushing, push bearing and straight, tie rod ball joint pin are too tight, that the lubrication is good, and that the lubrication may sometimes need to be adjusted.

There may also be inconsistencies in the weight of the left and right steering: turn the steering wheel left and right, and feel a point, and the light and weight of the two sides are different. The specific causes and solutions are as follows:

1) Reason: The valve is not properly adjusted, and the valve deviates from the middle position. The valve pre-opening clearance is on both shoulders.

The spool valve has dirt, which makes the reaction force and moving resistance of the spool valve or plunger poor. There is aerodynamic force on the cylinder side. Faulty valve body, frame deformation, or front suspension deformation ions.

To sum up, we can see that the difficulty of controlling the steering wheel during the driving process of the vehicle may be caused by different reasons, and we need to make our own judgment to solve the problem.

You should stop immediately to check your tire alignment wheels, or you may not have enough steering oil, but you should still find a repair shop to check it for safety.

At this time, you should choose to stop in an emergency, park the car on the side of the road, then put a fault sign, and then call a tow truck to tow the car to a repair shop or a 4S shop.

To deal with unstable steering wheels while driving, you must first master the correct steering wheel fixing method. The hands should be kept parallel to a slightly lower position in the middle of the steering wheel. During driving, the sitting position must be active, the steering wheel must be firmly held, and the line of sight should be as far away as possible.

In this way, we can detect as quickly as possible whether the body is parallel to the road. The farther we look, the sooner we can identify problems. When we need to fix the direction, tap the direction lightly and slowly return to a small angle adjustment.

Control the speed, stabilize the direction, and keep the vehicle stable. Maintain proper tire pressure to avoid getting too low. Finally, the rear wing can be installed to reduce the gas lift and increase the weight of the vehicle.

Many people think that the vehicle floats because the body weight is too light. In fact, this view is very one-sided. High-speed blasting is a complex problem.

This makes sense if the weight of the vehicle is one of the things that affects the control of the vehicle, but it does make you feel like it has nothing to do with the weight of the vehicle.

The performance of the filter is not ideal, and the travel of the soft suspension spring is sensitive to the vibration response of the body. It takes a long time for the shaking of the body to calm down. Therefore, in addition to poor stability at high speeds, in the event of a sudden crosswind or strong air flow, the soft suspension response will become strong, and it may even be necessary to slightly correct the direction and adjust the driving trajectory.

Height of the vehicle's center of gravity: The height of the vehicle's center of gravity affects the movement of the four tires during cornering and braking. When bending, the load is transferred to the outside wheels.

The greater the external load, the easier it is to feel the vehicle floating.

In fact, it's impossible to run in a straight line all the time when you get on the bus. Due to the influence of the road, it is necessary to correct the direction when it is noticed that the body is leaning. When the speed is high, the angle in the direction of the trimming must not be too large.

The principle of mastering two or three fingers is that the actual rotation distance in the direction should be within the width of two or three fingers. Tire parameters, including trim ratio, tire pressure, tread shape and size, all affect grip performance. The less grip the tires have on the ground, the less stable the vehicle will be, and the more obvious the subjective sensation of the head flying.

The steering wheel of the car is erratic, and it should be treated like this: the steering wheel can be regarded as a round dial, and the correct way to hold the steering wheel is to put the left hand at nine o'clock and the right hand at three o'clock, the stroke is like a clock, and the posture is 9:15 or 10:10; When turning the steering wheel, the steering wheel is pushed by the left and right hands to make the car turn naturally; When the steering wheel has been turned half a turn in your hand and you need to turn at a large angle, you can return to the right direction after you have finished turning as long as you repeat the above actions. Check the chassis suspension, if there is left and right drift in the steering wheel, first check whether the suspension has loose parts.

Check the chassis suspension to see if there are any loose parts, you can check the rubber limit block fixed in the groove of the steering machine, if it is seriously worn, it will cause the steering wheel of the car to be erratic.

Because it is very dangerous for the car steering wheel to fluctuate, it will seriously affect safe driving, so you should go to a 4S shop for repair as soon as possible.

We've talked about how to deal with emergencies like a flat tire on the highway before, but in reality it's not the only dangerous situation in driving. Have you ever thought that a steering wheel malfunction while driving is also a very dangerous situation? Next, let's take a look at how to deal with steering wheel failure.

First of all, it is important to understand that there are generally three types of steering wheel faults: functional failures, mechanical failures, and circuit failures or connector failures. In the face of these failures, we can take the following methods to deal with them:

1.For the case of function failure, the multi-function steering wheel of the general vehicle has functions such as adding and subtracting more volume, Bluetooth mobile phone call, and advancing and retreating more than one curve front rubber track. When these functions fail or are abnormal, you can manually operate the multi** button on the center console or the button with the same function on the touch screen to verify whether it is a function failure.

2.In the case of mechanical failure, keys are consumable parts that will shorten their life due to wear and tear in use. It cannot be ruled out that the function failure and uncontrollable quality caused by unreasonable quality and design and immature technology cannot be ruled out.

When the first functional verification is passed, the key can be checked. 3.In the case of a faulty circuit or connector, all keys have corresponding matching circuits and connectors, etc.

It is electrically connected to the control electronics. Accelerated oxidation of connectors, aging of circuits, oxidation of critical contacts, short circuits of connectors, false open circuits, etc. Improper use of the environment will cause the keys to fail.

It is recommended to use a special electronic instrument to check whether the circuit connection is abnormal. In the event of an emergency with a steering wheel malfunctioning, we need to take timely countermeasures, and the specific steps are as follows:1

Immediately raise the throttle and push the gear lever into low gear; 2.Evenly pull the parking car to control the high movement; 3.When the speed of the vehicle is significantly reduced, press the brake pedal to make the vehicle gradually stop; 4.

Turn on the hazard lights, turn on the headlights, honk or gesture. In short, do everything possible to signal other vehicles and pedestrians; 5.If you suddenly find that the steering is heavy, it should be a fault of the power steering system.

You need to quickly release the accelerator, reduce the speed of the car, and operate the steering wheel vigorously to hear the car reach the right place; 6.If the car can stay in a straight line and the road ahead allows it to drive in a straight line, emergency braking is not necessary. You need to press the brake pedal lightly and gently pull the parking brake lever to bring the car to a slow and steady stop; 7.

When the speed of the car is fast, if the direction is out of order, the front and rear wheels are not exactly in a straight line, and it is easy to overturn with emergency braking with the brake pedal. Therefore, it is safer to drag and slow down first, and then step on the emergency brake; 8.Finally, after the direction fails, remember not to coast in neutral, do not press the clutch pedal, and use the suppression resistance of the engine to achieve the purpose of deceleration.

Immediately release the accelerator pedal and push the shift lever to low gear. The above is how to deal with steering wheel failure, I hope it can help everyone's driving safety.

1.Don't panic, the driver should immediately and lightly open the accelerator pedal to allow the vehicle to drive at low speeds and tighten the handbrake evenly and firmly. 2.

If the speed of the vehicle drops significantly, apply the foot brakes at this time to bring the vehicle to a gradual stop. If the vehicle is driving at high speeds, especially when the front and rear wheels are not in a straight line, use the handbrake to slow down first, and then apply the emergency brake. 3.

At this time, it is necessary to send emergency signals to other vehicles and pedestrians, such as turning on the skin to shout emergency flashing lights, honking horns, gesticulating, etc. Do not use the emergency brake immediately to avoid overturning. 4.

Do not coast or press on the clutch at low speeds, so that the engine cannot suppress the power deceleration. Attachment: Reasons for loss of control of the steering wheel:

1. Steering system failure, such as sudden failure and loss of control of the steering gear; The steering system lacks oil and the direction is stuck. 2.Reasons for the wheel burning Tanye tires:

Air leakage, ** or other reasons, such as foreign body penetration, traffic accidents, etc. 3.Causes of failure of chassis components:

For example, some suspension devices are broken, loose, and fastening screws are loose or fall off. 4.The front and rear drive systems are malfunctioning.

1.Drivers don't need to panic. The accelerator pedal should be lifted immediately and gently to allow the motor vehicle to drive at a low speed and the handbrake should be tightened evenly and firmly.

2.If the speed of the car drops significantly, you need to apply the foot brake to stop the car, so that the car will gradually stop. If the car is driving at high speeds, especially when the front and rear wheels are not in a straight line, you need to use the handbrake to slow down first, and then apply the emergency brake.

3.At this time, it is also necessary to send emergency signals to other vehicles and pedestrians, such as turning on emergency flashing lights, honking, gesticulating, etc. Emergency braking cannot be used immediately to avoid overturning.

4.It is not necessary to coast at low speeds or to press the clutch, so it is not possible to use the engine to suppress power deceleration. Attachments:

Reasons for loss of control of the steering wheel:1There is a problem with the steering system, such as a sudden failure, the steering machine is out of control; The steering system lacks oil and the direction is stuck.

2.Tire causes: Flat air, ** or other reasons, such as foreign body penetration, travel accidents, etc.

3.Causes of failure of chassis components: such as the fracture of the suspension device, the lifting is too wide, and the fastening gong is lifted or dropped.

4. The front and rear drive systems are faulty.
