Active brake control system and control method of false stepping preventing accelerator pedal

Abstract

The invention discloses an active brake control system and control method of a false stepping preventing accelerator pedal. The active brake control method of the false stepping preventing acceleratorpedal comprises the steps of performing recognition and active brake control on driver false stepping behavior representation; combining an action of the accelerator pedal, a vehicle speed and driverexpression / sound recognition as an important judgement basis for intervention of a brake executing mechanism; making a reasonable judging logic and calculating a braking deceleration to guarantee that the brake executing mechanism intervenes in time if necessary and does not intervene when a driver normally operates the accelerator pedal; and finally, converting a desired braking deceleration into a reasonable four-wheel braking force; and using a corresponding executing mechanism to guarantee timely braking of a vehicle. The active brake control method of the false stepping preventing accelerator pedal has the advantages that the correctness of the recognition result is high, and the active braking reliability of the driver during stepping on the accelerator pedal by mistake is greatly enhanced.

Description

technical field [0001] The invention relates to the field of active safety control of automobiles, in particular to an active braking control system and control method for preventing a driver from stepping on an accelerator pedal by mistake. Background technique [0002] At present, the automobile industry is undergoing a transformation of "new four modernizations", that is, "electrification, networking, sharing, and intelligence". In this context, the advanced driver assistant system (Advanced Driver Assistant System, ADAS) has been widely studied, and the active obstacle avoidance control system, as an important part of the active safety of the vehicle in ADAS, has attracted more and more attention from researchers. . At present, the traffic scene in our country is complex. When a novice driver encounters an emergency, it is very easy to step on the brake pedal as an accelerator pedal due to nervousness. After the speed increases, the driver's panic will be aggravated, an...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the "driver's active behavior" strategy, most traditional active braking systems cannot avoid continuous collision accidents caused by the driver's "misstepping"

Even if the traditional active braking system does not adopt the "driver's active behavior" strategy, it will not be able to reduce the vehicle speed to a safe value within a limited distance in time due to the rapid increase in vehicle speed caused by the driver's slamming on the accelerator pedal

[0005] (2) A small number of active braking studies that consider the phenomenon of "false stepping" are not accurate enough to identify and judge the driver's mistaken stepping, and it is difficult to ensure that the system intervenes in time when necessary and does not intervene when the driver normally manipulates the accelerator pedal to accelerate the vehicle vehicle movement

[0006] (3) The judging logic design of the active brake controller has insufficient judgment basis, and it is impossible to accurately judge whether it is a false step while not misidentifying the driver's normal operation of the accelerator pedal as a false step. error"
