The invention discloses an automobile emergency braking auxiliary system. The automobile emergency braking auxiliary system comprises an electronic brake and an accelerator pedal, wherein the electronic brake is provided with a signal receiving module for receiving control signals; the accelerator pedal comprises a controller and is provided with a sensor; the sensor detects displacement of the accelerator pedal between an initial position and a fuel feeding position, converts the acquired displacement into detecting signals and transmits the detecting signals into the controller; the controller compares the detecting signals of the accelerator pedal reset from the fuel feeding position to the initial position with a set value preset inside the controller, and the electronic brake receivescontrol signals via the signal receiving module so that the control signals can control on and off of the electronic brake. The automobile emergency braking auxiliary system can automatically slow avehicle down at the initial stage when an operator lifts the right leg off the accelerator pedal, thereby greatly shortening the response time of emergency braking of the operator.

The invention relates to the braking safety aspect of heavy tractor semi-trailers, and discloses an auxiliary emergency braking system applied to a heavy tractor semi-trailer. The auxiliary emergency braking system is connected with a semi-trailer air brake system; when the pedaling speed of stepping on a braking pedal by a driver is higher than a threshold value, the auxiliary emergency braking system is opened, a vacuum sucker is controlled through a pneumatic lifting device to ascend or descend, air in the vacuum sucker is pulled by a vacuum pump to reach the vacuum degree needed by the auxiliary emergency braking system to generate a braking force, so that the semi-trailer is assisted to be emergently braked, and besides, the vacuum degrees of a left device and a right device are controlled to be different in turning braking to realize the stable control of the semi-trailer.

A magnetic anti-emergency braking auxiliary device based on capacitance control, relating to the technical field of auto parts, a magnetic anti-emergency braking auxiliary device based on capacitance control, including a pedal, the bottom of the pedal is movably connected with a telescopic rod, and the telescopic rod The middle part and the bottom near the pedal are fixedly connected with a dielectric plate, and the inner bottom wall of the telescopic rod is fixedly connected with a spring one. The magnetic anti-emergency braking auxiliary equipment based on capacitance control is used in conjunction with the electromagnet and the magnetic block. When an emergency occurs, the electromagnet will be in a energized state and will generate the same magnetism as the outside of the magnetic block. At this time, the clamping block will protrude inward under the action of the magnetic block and engage with the card slot, effectively restricting the movement of the slider, and at the same time restricting the pedal from continuing to step down, thus achieving the goal of avoiding the acceleration of the vehicle. The situation can effectively reduce the severity of the accident and ensure the safety of the driver.
