Brief description of the drawings
Fig. 1 is the control system structural representation of vehicle electric throttle safety precaution controller;
Fig. 2 is the control panel structural representation of vehicle electric throttle safety precaution controller.
Detailed description of the invention
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As Fig. 1-2, controller of the present utility model comprises microprocessor, throttle input interface and throttle output interface; In microprocessor, be integrated with A/D converter and D/A converter; The mouth of E-gas is connected with the A/D converter in microprocessor by throttle input interface; D/A converter in microprocessor is exported throttle signal to vehicle ECU by throttle output interface; The I/O interface of microprocessor connects the brake signal of vehicle.
Described vehicle electric throttle safety precaution controller also comprises the mode switch being connected with the I/O interface of microprocessor.
Described vehicle electric throttle safety precaution controller also comprises idle knob and power stage restriction knob, and idle knob is all connected with the A/D converter of microprocessor with power stage restriction knob.
Described vehicle electric throttle safety precaution controller also comprises the annunciator being connected with microprocessor.
ECU is electronic control unit, or is called main control unit.Idle knob and power stage restriction knob all adopt the rotor switch with potential device.
When the utility model is implemented, part that Motronic control maps throttle is connected with Engine ECU disconnects, be that accelerator pedal signal is directly inputted in microprocessor, after the optimal control and judgement of the utility model controller, simulate one group and the similar D/A voltage signal of Das Gaspedal output signal, this voltage signal is input to Engine ECU again.The signal that Engine ECU accelerator pedal signal port receives is by the utility model controller simulation output, thereby realizes the restriction control of identification, protection and throttle power to wrong throttle operation.
Former car engine efp signal, idle signal, power output signal carry out acquisition of signal by this controller A/D; Speed-slackening signal and mode switching signal are inputted by control system I/O mouth as on-off signal; Separately simulate an engine oil gate signal to Engine ECU system by D/A digital to analogy conversion; The signals such as sound and light alarm export to control LED lamp by I/O or buzzer phone is realized.
Take over from engine direct+5V power supply of controller power supply employing, has removed power-switching circuit from, simplied system structure, optimization system cost.
The utility model control panel as shown in Figure 2, has comprised idle knob, power stage restriction knob, mode selector switch and alert lamp.As long as idle knob is used for the initial start-up machine throttle at idle output of control engine under step on the accelerator state not, setting range is 2%-5%; Power stage restriction knob is for allowing maximum power output percentum, and setting range is 5%-100%; Mode selector switch is to switch control button under protected mode and normal mode, and under normal mode, engine output and throttle adjustment are unrestricted, and under protected mode, idle and power stage limitation function just work.When gathering way, throttle exceedes a threshold value, while particularly there is rapidly slam open or large throttle in driving procedure, on control panel, warning indicator lamp sends sound and light alarm, and control system will not respond the speed-up command of chaufeur, and driving engine is only now idling horsepower output.After chaufeur Das Gaspedal is less than 5%, sound and light alarm order is removed, and enters into conventional driving condition.In driving procedure, as long as step on brake pedal, no matter this while being throttle what, driving engine output throttle all becomes idling mode automatically.
Power regulation is to export different throttle signals to Engine ECU by D/A converter through throttle output interface, makes driving engine export different power, thereby reaches the object that regulates engine output.
