After the flameout, can the throttle, brake and gear be moved at will?

After the flameout, the throttle and brake can basically be hit at will, and only the traditional mechanical automatic gear can't be broken.

It is no problem to install an old driver in the car for a period of time after the flameout.

You can step on the accelerator at will after the flameout, mainly because most cars now use electronic accelerator pedals.

Different from the old car, it is just an electronic switch, which directly connects the accelerator pedal with the accelerator on the engine.

Just like: the TV remote control itself is not connected to the TV, and the TV mechanism is turned off. Press 1 122 on the remote control, up, down, left and right, ABAB, right?

Hefei University of Technology has a paper "Research on the Control of Engine Electronic Throttle", which was mentioned above.

Then the actual torque of the engine is estimated according to the information of actual engine speed, air volume, fuel volume, ignition advance angle and coolant temperature.

Then form a closed-loop torque control with the determined target torque, and finally output the information needed for ignition, fuel injection and air intake to control the engine.

A lot of complicated operations need no memory at all. Simply put, the accelerator pedal is just an electronic switch, and we don't need to know how it works. It will do it by itself.

The more you step on it, the faster it runs; Take one step less and run slowly, that's all.

After the car is turned off, the switch is turned off and no information is output. So it doesn't matter how you step on the accelerator after the car stalls, there is no response.

Just like: the phone has been turned off, no matter how you press the button, the phone will not respond, the same.

However, the only possible wear is the electronic accelerator pedal assembly. However, because most of the current electron accelerators use non-contact sensors based on Hall effect, their service life is relatively long.

The industry standard QC/T 977-20 14 "Technical Requirements for Automobile Electronic Accelerator Pedal Assembly" requires that the durability of the electronic accelerator pedal assembly should not be less than 6,543,800 times.

So don't worry too much: why does the pedal itself crack when you step on it?

Generally speaking, after the flameout, you can step on the accelerator at will, which will not have any impact on the car.

The reason is: the computer is turned off, the mouse and keyboard are pressed casually, and there is no response. You can only press the key if the keyboard key is broken.

You can step on the brakes after the flameout, but I don't think most of your friends can.

The brake is not the same as the throttle, it is not an independent switch.

Suzhou University wrote in a paper "Design and Calibration of Brake Pedal Angle Sensor Based on Hall Effect" that at present, most automobile braking systems adopt hydraulic braking.

In general, when the driver steps on the brake, the brake pedal moves backward, which is triggered by a valve to start the vacuum booster at the back.

Finally, the amplified pedaling force is transmitted to the brake cylinder of each wheel through the brake oil and the brake master cylinder, which pushes the caliper to generate braking force.

You don't need to remember so much. Anyway, you need a booster. Just stepping on your feet is equivalent to holding the bicycle tires with your hands. Can you stop it? Right?

In the previous naturally aspirated vehicles, the vacuum source of the vacuum booster was the intake manifold of the engine, and now most vehicles are equipped with electric vacuum pumps.

Neither the intake manifold nor the electric vacuum pump can provide enough vacuum after the car is turned off and powered off.

So under normal circumstances, although you can step on the brake pedal after the flameout, the pedal will become very hard, harder to step on than during normal driving, and basically can't move.

This is like saying: bone soup will become soup when heated, and will become frozen when the temperature is lower.

It should be noted that even if some models step on the brakes after the flameout and power failure, the brake lights will still be on. If you often step on it after the power is turned off, it may be that the battery is dead, so you need to pay special attention.

Whether the gear lever can move depends on the situation. Whether the shift lever can be broken at will depends on the situation.

Traditional automatic gears can't move at will.

For example, in an automatic transmission vehicle with a traditional gear shift lever connected by mechanical transmission, the gear shift lever can't be hit casually and can't be broken after flameout.

There is a paper in Automotive Technology magazine, which is mentioned in Noise Optimization of Unlocking Solenoid Valve of an Automatic Vehicle.

There is a solenoid valve under the shift control mechanism of automatic transmission car to lock the shift handle in P position. Only when the vehicle is powered on and the brake is pressed will the solenoid valve be unlocked.

Some cars are not only P gears, but also other gears, so it is possible to have such a locking mechanism.

It's like: the lock is locked and can only be opened with a key. If you poke the lock hole with something else, it won't open, and it may even break the lock, so the key can't be inserted, right?

So if you really encounter special circumstances, you have to shift gears in the case of power failure. Generally, only the emergency unlocking mechanism can be used to shift gears.

Some models even need to be disassembled to make shift panels; Some of them have things that can be unlocked by pressing. Please pay attention to this: the master is here.

The electronic gear lever can be moved at will, and you can play it at will. The reason is the same as the previous electronic throttle. It is not directly connected to the gearbox, just a switch.

But after the flameout and power failure, even if you break the gear lever over there, you can't shift gears.

The manual gear can be moved at will. After the manual gear is turned off, the shift lever can also move at will. Although the gearbox has shift action at this time, there is no need to worry about extra wear.

Take a shift shaft as an example: the ball head on it needs to bear the load of 1 100 N, the frequency is 10 ~ 30 times/min, and the period is 150000 times.

Really don't worry: after the flameout, it will be broken twice, and the test intensity is very high.

The automatic gear connected by traditional machinery can't be broken, so generally speaking, except for the automatic gear connected by traditional machinery, it can't be broken after the flameout and power failure, there is no big problem that other throttle, brake and gear can't be broken, so don't worry about breaking the car.

But if you step on the brake pedal, the taillight at the back will light up, so be careful that there is no electricity.
