Automotive emergency braking system

Abstract

The invention discloses an automotive emergency braking system which comprises a sudden stop button, a sensor group, a signal processor, a controller, executing mechanisms, a distance sensor, a speed sensor and an alarm apparatus. The executing mechanisms comprise power source cutting-off devices for cutting off power sources and brake supercharging devices for providing maximum brake force, wherein each power source cutting-off device comprises a main power source cutting-off switch, a branch power source cutting-off switch and a residual current sensor, the distance sensor and the speed sensor are connected with the input end of the controller, the alarm apparatus is connected with the output end of the controller, and the sudden stop button is connected with the input end of the sensor group. After the automotive emergency braking system is adopted and a driver needs to emergently brake and park a vehicle, the system can rapidly cut off a power source of the vehicle and meanwhile utilizes the maximum brake force allowable by a performance parameter of the vehicle to brake only by pressing down the sudden stop button, and the phenomenon that the vehicle cannot be timely stopped due to insufficient brake force during emergency baking.

Description

Technical field [0001] The invention relates to the field of automobile emergency braking, in particular to an automobile emergency braking system. Background technique [0002] With the development of economy and technology, automobiles have rapidly become popular, more and more people are driving vehicles, and the emergency situations that drivers encounter are becoming more and more complicated. Through investigation, it is found that when the driver brakes in an emergency, it is often unable to quickly step on the brake. [0003] The pedal is stepped on to the required level, and I rarely know the maximum braking force allowed by the vehicle I am driving. Therefore, it is difficult to grasp the best braking timing and the best braking force, so that it fails to perform the car’s due Maximum braking strength and braking potential, causing unnecessary traffic accidents. At the same time, it is not uncommon for drivers to step on the accelerator pedal incorrectly due to panic du...

AI Technical Summary

Problems solved by technology

[0004] The existing emergency braking assist system of automobiles is activated by the switching value of the brake pedal. Although it can exert most of the braking potential of the automobile, it does not take into account the driver's operation errors during emergency braking, such as stepping on the brake. Don't use force when pedaling

[0005] The auxiliary system cannot be turned on in time to play a role

In this regard, some improvements have been made in the prior art, such as assisting parking by installing auxiliary mechanisms on the car, but these auxiliary mechanisms are often not designed to exploit the maximum braking potential of the car, so they fail to make full use of the vehicle itself. performance

[0006] At the same time, the existing emergency braking system often adopts one braking method, which has no selectivity and poor pertinence
