unlocking action: after the automobile is started, a right foot is placed on the control pedal 21 and is stepped downwards, in the process of pressing by stepping downwards, the unlocking pedal 22 is acted by force to rotate downwards, the unlocking connecting rod I241 is driven to move downwards while rotating downwards, under the action of the transmission of the connecting rod between the unlocking connecting rod I241 and the unlocking connecting rod III 243, the top end of the unlocking connecting rod II 242 moves outwards to be separated from a clamping groove on the fixed support plate 1, the control pedal 21 is continuously stepped downwards for a section of displacement, and the automobile is in a braking state;

acceleration action: then, when the forward gear is engaged, the right foot is loosened slowly, under the action of elastic pulling force of a pressure spring 44 in the arc-shaped sleeve 41, the control pedal 21 is driven to move upwards slowly through the transmission effect of the arc-shaped connecting rod 43 on the force, so as to realize the control on the automobile accelerator, the running state of the automobile is controlled through the loosening degree of the right foot and the oil inlet amount of the accelerator pulled by the force, and the unlocking pedal 22 is always in a trampling state, so that the unlocking connecting rod II 242 is always in a tightening state, and cannot be jammed with a clamping groove on the fixed support plate 1, so that the control pedal 21 can move up and down conveniently and flexibly;

deceleration action: when the control pedal 21 is stepped downwards, the downward displacement of the control pedal 21 is converted into the extrusion amount of the pressure sensor 34 under the action of the transmission of the connecting rods of the brake connecting rod I31 and the brake connecting rod II 32, the brake control system is further utilized to adjust the brake force of the brake oil pump according to the extrusion amount of the control pedal 21 to the pressure sensor 34, so that the deceleration or braking action of the automobile is completed, the speed and the degree of the control pedal 21 moving up and down are controlled by applying different pressures to the control pedal 21, and the regulation and control of the automobile speed are further completed;

unlocking action: when the vehicle is required to stop, when the control pedal 21 is pressed down to make the vehicle in a braking state, then the neutral gear is put into gear and then the right foot is pulled away, firstly the unlocking pedal 22 loses pressure, the unlocking pedal 22 is always pressed by the upward movement under the elastic force of the reset spring 23, and under the transmission action of the unlocking connecting rod I241 and the unlocking connecting rod III 243, the supporting pressure plate 244 is always attached to the front surface of the fixed support plate 1, at the same time, when the pressure of the right foot of the control pedal 21 is lost, the control pedal 21 is driven to move upwards under the action of the pressure spring 44, when the control pedal 21 drives the unlocking pedal 22 and the unlocking mechanism 24 to integrally move to the position of the slot on the fixing support plate 1, the support pressure plate 244 will momentarily clamp the control pedal 21 against further movement and lock the throttle, allowing the control pedal 21 to return to its initial position and be in a balanced (neither braking nor fueling) condition.
