Abstract
The utility model relates to a non-contact intelligent electronic throttle belonging to the automotive electronic technical field for solving security problem caused by mis-stepping on the throttle when a driver performs emergency braking. The assemblies of the utility model system include a non-contact sensing element, a throttle pedal, a control unit, an interruption performer, and a brake treadle. The combined mode is that: a non-contact angular transducer is arranged on the throttle pedal, when the throttle pedal is stepped down, the non-contact angular transducer produces a frequency impulse with a certain angle which is transferred to the control unit. The control signal is sent to the throttle interruption performer through the control unit to lead a throttle pull wire to be inoperative. Simultaneously the control signal sent out by the control unit is transferred to an actuator solenoid valve which is mounted on the brake treadle. The actuation is produced by the actuator solenoid valve to lead the brake treadle to brake, thereby enabling an automobile to quickly brake. The utility model can judge whether the drive has made a faulty operation by variations of angles of a detecting foot pedal, and then adopt safety precautions to shut down the fuel line and brake vehicles.
Description
Technical field:
The utility model relates to a kind of non-contacting intelligent electric throttle, mainly is that mis-accelerator pressing causes dangerous safety problem when solving the chaufeur emergency braking, belongs to the vehicle electronics applied technical field.
Background technology:
Mainly be that mis-accelerator pressing causes dangerous safety problem when solving the chaufeur emergency braking.At present, at emergency braking in emergency circumstances, still decided by the speed of response of chaufeur according to the individual, this mode can not ensure driving safety fully.This utility model system has then considered this situation fully, can ensure the danger that is in case of emergency caused by maloperation fully.
Summary of the invention:
The purpose of this utility model just when preventing the chaufeur emergency braking mis-accelerator pressing cause danger and the anti-throttle maloperation electronics package of a kind of automobile of design-calculated.
The utility model comprises sensor, Das Gaspedal, control unit, interruption actr (electromagnetic switch), brake pedal.Wherein control unit comprises additional devices such as micro controller system, crystal oscillator, resistance and electric capacity.
The purpose of this utility model can realize by following measure:
Noncontacting proximity sensor is installed on the stretcher (is installed in the position that does not influence normal running), this noncontacting proximity sensor adopts universal electromagnetic formula non-contact angle/placement coil pickup, use electromagnetic induction principle: when the stretcher angle changes, noncontacting proximity sensor moves by the induced signal dish, cause the variation of fixed end coil inductance, handle the impulse singla that obtains different frequency by oscillating circuit, be transferred in the control unit.In control unit, according to this and the last frequency that obtains, by algorithm, the gasoline throttle angle that twice needs before and after calculating is poor.Control unit judges that to the difference that obtains if surpassed a definite value, just maloperation may take place in explanation.Control unit just transmits control signal to oil circuit actr electromagnetic valve immediately, makes the electromagnetic valve energising, closes oil circuit fully.Simultaneously, control unit also transmits control signal to brake pedal actr electromagnetic valve.After the energising of brake pedal electromagnetic valve, energy control brake pedal makes brake pedal produce braking maneuver, and abrupt deceleration vehicle is to ensure safety.
Certain definite value of the utility model indication can be set according to actual conditions.
The utility model judges by the variable quantity that detects the stretcher angle whether chaufeur maloperation has taken place, and then takes safety measures, and closes oil circuit, abrupt deceleration vehicle; Simultaneously, control unit of the present utility model also can be made a module, is nested among the ECU of car load, and good compatibility is arranged.

1-Das Gaspedal, 2-sensor, 3-control unit, 4-brake pedal, 5-electromagnetic valve, 6-electromagnetic valve, 7-spring, 8-spring
Specific embodiments:
In conjunction with the accompanying drawings, further the utility model is described.
The utility model is installed in non-contact angle sensor 2 on the stretcher 1 and (is installed in the position that does not influence normal running), this non-contact angle sensor 2 adopts universal angle electromagnetic induction sensor, use electromagnetic induction principle: when stretcher 1 angle changes, noncontacting proximity sensor 2 moves by the induced signal dish, cause the variation of fixed end coil inductance, handle the impulse singla that obtains different frequency by oscillating circuit, be transferred in the control unit 3.In control unit 3, according to this and the last frequency that obtains, by algorithm, the gasoline throttle angle that twice needs before and after calculating is poor.3 pairs of differences that obtain of control unit judge that if surpassed a definite value, just maloperation may take place in explanation.Δ θ value and definite value L are compared, if Δ θ＜L shows vehicle ' under normal condition, system does not start.If but Δ 0＞L illustrates maloperation has taken place.At this moment, control unit 3 just transmits control signal to actr electromagnetic valve 6.Actr electromagnetic valve 6 is electromagnetic valves that are installed on the throttle, after the energising, closes oil circuit fully.Simultaneously, control unit 3 also transmits control signal to actr electromagnetic valve 5.Actr electromagnetic valve 5 is connected with brake pedal 4, and gives energy control brake pedal 4 under the situation of actr electromagnetic valve 5 signals at control unit 3.Make brake pedal 4 produce braking maneuver, abrupt deceleration vehicle is complete with service truck.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
