The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is specified.

A kind of alarm set that prevents that the automobile accelerator pedal mistake from stepping on; Like Fig. 1, shown in Figure 2, comprise power supply 1, controller 3, induction car speed sensor 4, car speed sensor magnetic runner 5, Das Gaspedal IS Idle Switch 7, active type infrared induction device 10, speech prompting device 12, light prompt device 13 with open contact.

Whole device adopts the 12V power voltage supply, and power supply 1 is connected in series through source switch 2 and controller 3; Controller is equipped with rectifying circuit for 3 li the alternating signal that induction car speed sensor 4 transmits is converted into voltage regulation signal;

Induction car speed sensor 4 is installed on the automotive driven wheel suspension, and car speed sensor magnetic runner 5 is installed on the flower wheel axletree 6; Flower wheel axletree 6 drives 5 rotations of car speed sensor magnetic runner when vehicle '; Magnetic field is changed; Induction car speed sensor 4 produces exchange current and passes to controller 3 through input end In (1); Rectifying circuit through in the controller 3 is converted into direct current (DC) with alternating current, thereby judges whether automobile is in motoring condition.

Das Gaspedal IS Idle Switch 7 is contained in below the bridge column; The Das Gaspedal IS Idle Switch has open contact, and open contact is aimed at hard-wired plush copper 9 on the Das Gaspedal gangbar, when the chaufeur pin unclamps Das Gaspedal 8; Plush copper 9 contact open contacts; Das Gaspedal IS Idle Switch 7 is just in time closed, and signal is passed to controller 3 through input end In (2), thereby judges whether Das Gaspedal 8 is in idling mode.

As shown in Figure 1, active type infrared induction device 10 is installed in control desk below (facing brake pedal), and the infrared beam of its infrared transmitter emission is over against brake pedal 11 middle (like Fig. 2), and infrared receiving set receives the infrared beam by the brake pedal reflected back.When chaufeur is placed on pin on the brake pedal; One of infrared emission light beam and folded light beam are stopped to make receiver can't receive the infrared external reflection light beam; Proved that chaufeur has moved on to pin on the brake pedal from Das Gaspedal; At this moment active type infrared induction device 10 sends signal, and signal is passed to controller 3 through input end In (3), and controller 3 judges according to the signal that receives whether the chaufeur right crus of diaphragm is placed on the brake pedal 11.

Among Fig. 1, speech prompting device 12 is installed on the control desk panel, and is connected with controller 3 mouth Ou (1).Light alarm set 13 is installed on the gauge panel, and is connected with controller 3 mouth Ou (2).In Fig. 2, after Das Gaspedal IS Idle Switch 7 closures,, will give a warning through speech prompting device 12 and light prompt device 13 if controller 3 does not detect the signal that active type infrared induction device 10 transmits after two seconds.And warning has preceence; When entertainment selections such as playing back music in the car; Controller 3 can temporarily automatically stop entertainment selection, transfers to giving a warning, and until chaufeur pin is placed on the brake pedal; When active type infrared induction device 10 sent signal to controller 3, alarm set stopped to continue warning.

Prevent that the alarm set principle of work that throttle mistake is stepped on from being: when vehicle in the process of moving, the chaufeur pin unclamps after the Das Gaspedal 8, and Das Gaspedal IS Idle Switch 7 is closed, and transmits signals to controller 3.When the chaufeur pin unclamps Das Gaspedal after two seconds; If chaufeur is not placed on right crus of diaphragm on the brake pedal; Controller 3 does not detect the signal that transmits from active type infrared induction device 10; Will send signal to alarm set, remind chaufeur that right crus of diaphragm in time is placed on the brake pedal 11.Make chaufeur form good driving habit, avoid in case of emergency, panic because of chaufeur, forget whether right crus of diaphragm is placed on the brake pedal, step on and Das Gaspedal is used as brake pedal by mistake, cause the accident.
