Embodiment 1
[0080] Such as image 3 As shown in , it is the judging process of the driver accidentally stepping on the accelerator when parking. When the driver is parking, step on the accelerator pedal when the vehicle speed is 10km / h, the pedal strength is 150N, and the accelerator pedal opening is 95%.
[0081] Step 1: The information collection module collects the vehicle speed signal through the sensor as 10km / h, and the acceleration pedal force as 150N;
[0082] Step 2: The ECU judges that the vehicle speed signal is lower than the vehicle speed threshold, and it is judged to be normal;
[0083] Step 3: The ECU judges that the accelerator pedal force parameter value 150N is greater than the second threshold value of the accelerator pedal force, and that 95% of the accelerator pedal opening is greater than the opening threshold value, and determines that the driver accidentally steps on the accelerator pedal.
[0084] Such as Figure 4 As shown in FIG. 1 , it is the judgment proce...

The invention relates to the technical field of automobile active safety, and discloses a method for judging misoperation of an accelerator pedal and an anti-misoperation system. First of all, the accelerator pedal is divided into two types by mistake. One is that when the vehicle is running, when an obstacle or other moving source suddenly appears in front of the vehicle, the driver quickly steps on the accelerator pedal as a brake pedal due to nervousness and panic; When parking or other low-speed driving conditions, the behavior of accidentally stepping on the accelerator occurs unconsciously, and the two different situations are distinguished by the speed of the vehicle. For different types of misstepping on the accelerator, different parameters are used for identification and judgment. The strength of the accelerator pedal is used to judge the misstepping of the accelerator in emergencies. The method can improve the recognition accuracy of accelerator pedal misoperation, significantly reduce missed and misjudgment phenomena, and effectively distinguish normal acceleration behaviors such as accelerator misstepping and rapid overtaking, slow start, and rapid start.
Description
technical field [0001] The invention relates to the technical field of automobile active safety, in particular to a method for judging misoperation of an accelerator pedal and an anti-misoperation system. Background technique [0002] In recent years, with the rapid development of my country's economy and the rapid development of the automobile industry, the number of car ownership and drivers has continued to increase at a high level, followed by a continuous increase in the rate of traffic accidents and a large number of casualties and property losses. In these traffic accidents Among them, the traffic accidents caused by the driver's operation error are the most common, and the accidents caused by the wrong operation of the accelerator as the brake are not uncommon. Therefore, it is very necessary to develop the automobile active safety protection technology to deal with this problem. [0003] At present, many scholars have conducted research on the method and principle of...
