Detection and Control Method of Preventing Misstepping on Accelerator of Passenger Cars

Abstract

The invention discloses a detection and control method for preventing accidental stepping on the accelerator of a passenger car, comprising step 1: collecting vehicle state signals; step 2: whether the vehicle is in a static or low-speed state, and if yes, execute step 3; otherwise, execute step 8; step 3: Whether the release time of the brake pedal is less than the time threshold, if yes, execute step 4, otherwise, execute step 8; step 4: whether the rate of change of the accelerator pedal exceeds the threshold of the rate of change of the accelerator pedal and whether the depth of the accelerator pedal is greater than the threshold of the depth of the accelerator pedal, if yes, execute step 5. Otherwise, go to step 8; step 5: if the accelerator is accidentally stepped on, enter the anti-accelerator pedal misstepping control mode; step 6: if the accelerator pedal is released and the brake pedal is stepped on, return to step 5, otherwise go to step 8; Step 7: Exit the anti-accelerator pedal accidental depression control mode; Step 8: The bus runs normally. The invention can accurately detect the misstepping behavior of the accelerator in the low-speed driving scene of entering and leaving the station, and properly control the response of the power system.

Description

technical field [0001] The invention relates to a method for controlling a power system of an automobile, in particular to a method for detecting and controlling a passenger car to prevent accidental stepping on the accelerator. Background technique [0002] During the operation and use of buses, there are relatively frequent low-speed driving in and out scenarios. The driver’s labor intensity is high, and pedestrians and bicycles are prone to suddenly appear around the vehicle. When dealing with this emergency situation, the driver has to Mistaking the accelerator pedal for a sudden step on the brakes can lead to serious accidents. [0003] In order to avoid the accidents of accidentally stepping on the accelerator, many vehicles have adopted the technology of preventing the accidental stepping on the accelerator pedal, such as: Chinese invention patent application CN201710319061. The sensor unit for measuring human physiological indicators collects in real time whether th...
