The invention provides brand-new methods for judging and preventing mistaken stepping of an accelerator. Double judgment is adopted when whether the accelerator is mistakenly stepped or not is judged,misjudgment is avoided, firstly, the real-time accelerator opening degree is compared with a set opening degree parameter, when the real-time accelerator opening degree exceeds the set opening degreeparameter, the stepping speed of an accelerator pedal after the real-time accelerator opening degree exceeds the set opening degree parameter is judged, the stepping speed of the accelerator pedal atthe moment is compared with a set speed parameter, when real-time values in double judgment both exceed the set parameters, it is identified that the accelerator is mistakenly stepped, and the reasonable and precise effects are achieved; meanwhile, the opening degree parameter and the speed parameter are set in a default mode and in a self-learning mode; and a vehicle can enter into the self-learning mode after being powered on, vehicle ignition is not needed, the entering mode is that the self-learning mode can be entered when the set number of times of mistaken stepping is reached within the set time, even if the vehicle enters into a self-learning state after being ignited, the vehicle is in an idling state at the moment, and thus the danger does not occur.

The invention discloses a method and a device for preventing a driver from treading an accelerator pedal by accident, belonging to the technical field of automobiles. The method comprises the following steps of acquiring the current movement degree of the accelerator pedal, judging whether the current movement degree of the accelerator pedal is more than a preset movement degree threshold, and cutting off the power of the automobile if the current movement degree of the accelerator pedal is more than the preset movement degree threshold. The device comprises a movement degree acquisition module, a judgment module and a cutting-off module. The current movement degree of the accelerator pedal is acquired firstly, when the current movement degree of the accelerator pedal is more than the preset movement degree threshold, the power of the automobile is cut off, so that the driver can automatically cut off the power when the driver treads the accelerator pedal by accident and prevent the event of treading the accelerator pedal by accident, thereby improving the accuracy of preventing the driver from treading the accelerator pedal by accident.

The invention discloses an automotive accelerating device. An accelerator pedal is connected to an automotive body through an adapting piece, a spring is connected to the tail end of the accelerator pedal, the other end of the spring is connected with a stepping motor, the stepping motor is fixedly installed on the automotive body and is electrically connected with a single chip microprocessor, and a control switch is arranged between the single chip microprocessor and a power source. The spring is arranged at the corresponding end of the pedal position of the accelerator pedal, the stepping motor is arranged at the bottom of the spring, the elastic force of the spring is adjusted through the stepping motor, and when an automotive starts or stops, a driver opens or closes the single chip microprocessor through the switch to control the stepping motor, the elastic force of the spring is adjusted, and therefore the drawing force for the accelerator pedal from the spring is adjusted, and the aim of preventing an accelerator and a brake from being stepped on by mistake is achieved.
