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 an accelerator pedal misapplication detection method for an electric automobile. The accelerator pedal misapplication detection method for the electric automobile comprises the steps of acquiring real-time speed, accelerator pedal opening-degree information and steering wheel angle information of the electric automobile, and barrier information around the automobile; and detecting accelerator pedal misapplication of the electric automobile according to the real-time speed, the accelerator pedal opening-degree information and the steering wheel angle information of the electric automobile, and the barrier information around the automobile. The accelerator pedal misapplication detection method for the electric automobile provided by the embodiment of the invention is completely based on existing various parts and structures of the automobile, realizes information communication between controllers through a CAN network, and completely adopts a software manner to realize accelerator pedal misapplication detection; and meanwhile, according to the method, the overtaking intention of a driver can be intelligently recognized, the misjudgement of accelerator pedal misapplication is avoided, the structure is simple, and the implementation cost is low.

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.

The invention relates to a new-energy or hybrid-power micro electric automobile, comprising a frame, one to three longitudinally arranged anticollision individual seats, an anticollision panel, a steering system, a front wheel assembly, a rear wheel assembly, wheel hub motors, a braking system, an adjusting controller, an electronic differential mechanism and LED lamps. The power supplies of the new-energy or hybrid-power micro electric automobile can be lithium batteries or super capacitors or fuel batteries or nickel-hydrogen batteries or hybrid power. Because the fuel batteries have special requirements for temperature and humidity, a front cooling air inlet scoop and an upper cooling air inlet scoop are additionally arranged. The whole new-energy or hybrid-power micro electric automobile has the advantages of small volume, light weight, simple structure, safety, reliability, energy conservation, and emission reduction, and is easy to operate, thereby organically integrating the economic, social and environmental benefits and meeting the needs of a part of people.
