Control system for preventing driver from stepping on automobile accelerator by mistake and control method thereof

Abstract

The invention discloses a novel intelligent device for preventing a driver from stepping on an automobile accelerator by mistake. An acceleration sensor and a gyroscope which are connected with a controller are adopted to monitor the acceleration and running state of an automobile when the driver steps on the accelerator, collected data is compared with preset threshold values, data about the deflection direction and degree of the gyroscope are compared with preset threshold values, when two conditions are met at the same time, it is determined that the driver steps on the accelerator by mistake, a gasoline supply system ECU stops supplying gasoline, an automobile emergency braking module conducts emergency braking, and the driving safety of the automobile is improved; the method is easy to control and operate, high in measurement precision, not easy to affect by the external environment and capable of not causing hidden safety problems; the device for preventing the driver from stepping on the automobile accelerator by mistake is simple, low in investment cost, suitable for large-scale popularization and application, a detection method of the device has the advantages of being intelligent, automated and high in reliability, and the occurrence of traffic accidents can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to a control system and a control method for preventing accidental stepping on the accelerator of an automobile. Background technique [0002] In recent years, with the rapid improvement of the economic level, the number of car ownership has risen rapidly, but the ensuing traffic accidents have also exploded in large numbers. Especially for automatic transmission vehicles, in an emergency, the probability of mistakenly stepping on the accelerator is greatly increased. The situation of deceleration is suddenly accelerated due to mistaken stepping, which will aggravate the severity of traffic accidents, cause heavy economic losses and cause casualties at the same time. [0003] Existing automotive accelerator accident prevention devices use the mode of accelerator acceleration sensor combined with distance sensor, accelerator pressure sensor or sound information recei...

Problems solved by technology

Especially for cars with automatic transmission, in an emergency, the probability of mistakenly stepping on the accelerator is greatly increased. The situation of deceleration is suddenly accelerated due to mistaken stepping, which will aggravate the severity of traffic accidents, cause major economic losses and cause casualties

[0003] Existing automotive accelerator accident prevention devices use the mode of accelerator acceleration sensor combined with distance sensor, accelerator pressure sensor or sound information receiver. The combination of accelerator acceleration sensor and distance sensor needs to collect and process information from other traffic participants, and time delay often leads to errors. Judgment, in the complex traffic environment, the distance sensor will be affected by bad weather, sound waves and electromagnetics, which will distort the distance. Combined with the sound information receiver, it will be affected by the passengers in the car.

In an emergency situation, a car accident often occurs in an instant, and the above-mentioned car accidentally steps on the accelerator, and the control device responds slowly and has low reliability.
