Under normal conditions, the differences between throttle and brake are roughly as follows:

the throttle is looser and easier to step on than the brake, and the magnitude of the throttle step is relatively small, e.g., varying by approximately 30 degrees from 0 to 160 yards.

First, in a normal driving situation, the stepping width of the accelerator is very small, and even in a case of passing, the accelerator is not rapidly stepped (here, the angular velocity at which the accelerator is stepped, not the pressure, is fed back to the pressure, and may be equivalent to the instantaneous pressure, and in a normal situation, it is impossible to generate a very large instantaneous pressure).

Under normal conditions, the driver who steps on the accelerator by mistake can not step on the accelerator at a high speed, and under normal conditions, the driver who steps on the accelerator by mistake can all respond to, so only step on the accelerator by mistake under special circumstances to what aim at, reduce the accident risk that the accelerator was stepped on by mistake under the emergency.

In emergency situations such as sudden braking, a person can quickly step on the brake in response, and at the moment, if the person steps on the accelerator by mistake, the accelerator can receive a large instant pressure and generate a large angular velocity due to the fact that the accelerator is easy to step on, so that accidents are caused.

The pressure sensor of the present embodiment may also use an angular velocity sensor.

Wherein the activation threshold may be an instantaneous pressure threshold or an acceleration threshold, respectively.

If the data collected by the detection sensor 604 exceeds the instantaneous pressure threshold or acceleration threshold, the steering engine is controlled to rotate, and the conversion from the accelerator to the brake is realized. And a pressing sleeve 602 is connected on the detection limit sleeve 605 in a sliding manner, and a pressure bearing spring 603 is installed in the pressing sleeve 602.

When the operating assembly 6 is used, once a user steps on the main accelerator pedal 301, the main accelerator pedal 301 pushes the pressing sleeve 602 and presses the pressure bearing spring 603, so that the detection sensor 604 can obtain required data, and then data comparison can be performed to confirm whether the steering engine on the rotary column 401 is started.

Specifically, the second main feature of the linkage device is that the detection mounting block 601 is quickly taken away from the lead screw cover 606 by being taken away from the lead screw cover, so that the brake condition of a user can not occur on a muddy road or off road, and once the linkage device is required to be used, the detection mounting block 601 only needs to slide to the original position and the support rod 607 is inserted into the fixing clamp cover 613, the structure is simple, the cost is low, the lead screw cover 606 with the distance from the detection mounting block 601 is arranged on the bearing frame 1, the fixing clamp cover 613 is arranged on the surface of the detection mounting block 601, and the support rod 607 inserted into the fixing clamp cover 613 is arranged on the bearing frame 1.

The support rod 607 has an L-shaped structure, so that the support rod 607 can be inserted normally without using any auxiliary tool when being inserted into the fixing clip 613, and the cross section of the support rod 607 has a rectangular structure, so that the detecting and mounting block 601 can be fixed more stably.
