Description

Acceleration Restriction System for Preventing Multifunction of Acceleration Pedal The present invention relates to preventing sudden acceleration of a vehicle. Generally, the vehicle has an accelerator position sensor (APS) that converts the amount of pressure applied to the accelerator pedal into voltage and inputs it to an Electronic Control Module (ECM), and the ECM controls the engine output based on the input voltage. The invention aims to prevent sudden acceleration malfunction of the vehicle by configuring an acceleration limiting device between the APS and the ECM. The prior art related to the present invention is disclosed in Korean Registered Patent No. 10-187125 (September 28, 2012). FIG. 1 is a flowchart of a conventional automatic transmission control method for preventing abnormal rapid acceleration of a vehicle. In FIG. 1, the conventional automatic transmission control method for preventing abnormal rapid acceleration of a vehicle comprises a precondition verification step (S11), a braking count verification step (S12), a throttle opening verification step (S13), and a vehicle speed verification step (S14), each step being as follows. First, the above-mentioned precondition verification step (S11) is a step for determining whether the preconditions for the neutralization step (S20) for prohibiting abnormal rapid acceleration are satisfied. As preconditions for the neutralization step (S20) to be executed after the vehicle is started, a plurality of conditions are checked, namely whether the gear lever is in the D or R position, whether the gear lever sensor, vehicle speed sensor, gear lever control solenoid valve (if a shift-by-wire is installed), transmission solenoid valve, throttle position sensor, and brake sensor are operating normally, and in the case of a vehicle capable of auto-cruise, whether the auto-cruise is turned off. At this time, if it is confirmed that any of the above preconditions are not satisfied, the automatic transmission control routine of the monitoring step (S10) according to the present invention is terminated. That is, the automatic transmission does not perform hydraulic control according to the present invention even if abnormal rapid acceleration occurs. In addition, the braking count verification step (S12) is a step of accumulating the number of braking operations of the brake and comparing it with a set value (F). When it is confirmed that all of the multiple preconditions are satisfied in the precondition verification step (S11), the number of braking operations executed in the current driving cycle from the start of the engine until the point in time when the braking count verification is performed is counted and compared with a predetermined set value (F), for example, about 2 times. As a result, if it is confirmed that the accumulated number of braking operations is less than the set value (F), it is considered that the reliability of the braking device is insufficient, and the monitoring step (S10) is terminated. That is, the set value (F) is considered as the minimum number of braking operations executed at the beginning of driving, and if the number of braking operations verified in the braking count verification step (S12) is less than the set value (F), it is considered that the brake is faulty, and just as the preconditions are not satisfied in the precondition verification step (S11), the cause of the abnormal sudden acceleration is considered to be a brake failure, and the control routine below the monitoring step (S10) is terminated. Alternatively, the reliability of the braking device may be improved by using the braking count value stored in the previous driving cycle by executing the previous braking count verification step (S15). Here, the previous driving cycle represents the driving state caused by the engine immediately before the current engine starts, and the current driving cycle represents the engine state currently continuing. Here, the previous braking count verification step (S15) consists of a previous braking count inquiry step (S151) and a previous braking count comparison step (S152). If it is confirmed that there have been brakings less than or equal to a set value (F) since the vehicle started driving in the current driving cycle, the number of brakings from the engine start in the previous driving cycle up to the point in time when the number of brakings in that cycle is verified is queried in the previous braking count inquiry step (S151), and the queried previous accumulated braking count is compared with a previous set value (PF), for example, set to 3 times, in the previous braking count comparison step (S152). As a result, if the previous accumulated braking count is greater than or equal to the previous setting value (PF), the routine according to the monitoring step (S10) is continued. Conversely, if the comparison result confirms that the accumulated braking count is smaller than the previous setting value (PF) even
