As shown in Figure 1, automatic collision-proof controller for motor vehicles of the present invention comprises: a micro controller system 100, several wave emitters 101, a speed of vehicle detector 102, several wave-receivers 103, a brake controller 104, and a footfeed controller 105.This micro controller system 100 couples with wave emitter 101, speed of vehicle detector 102, wave-receiver 103, brake controller 104 and footfeed controller 105 respectively, so that transmitting signals and processing signal.
See also Fig. 3.As shown in Figure 3, the automobile 200(at the automatic control device that is equipped with power actuated vehicle collision-proof of the present invention advances along the arrow A direction) the place ahead be respectively fitted with three wave-receivers 103,103,103.Wave-receiver 103 is the strip shape housing, and its long axis direction is parallel with the car direct of travel, have respectively in it along seven of long axis direction configuration receive ripple station 103a, 103b, 103c ... 103g.Automobile 200 the rear then be equipped with three wave emitters 101,101,101.The structure of this wave emitter 101 system as shown in Figure 6, have seven transmitting channel 101a, 101b, 101c ... 101g, the transmitting range difference of each channel.Therefore, produce seven regional I, II, III in the back of automobile 200 ... (seeing also Fig. 5).In automobile 200 enters each zone, wave-receiver 103 on the automobile 200 just can receive that wave emitter 101 sent apart from signal, if the frequency of this signal is consistent with setting value, then micro controller system 100 sends warning signal entirely to give an order simultaneously to limit and refuels and brake (will describe in detail in the back).
In addition, the downrange of the wave emitter 101 of both sides, automobile 200 rear system is toe-in slightly as shown in Figure 3, with convenient automobile 200 in about the signal forward of emission can be passed to the rear when turning automobile 201(see also Fig. 9).In addition, when automobile brake or about when changeing, the swings of about 30 degree about the wave emitter of both sides can be done are with the unlikely overtaking collision of the vehicle of guaranteeing the rear.
The operational scenario of automatic collision-proof controller of the present invention below will be described.See also Fig. 2, when automobile starting, automatic control device of the present invention also starts automatically.This moment, micro controller system 100 can send the speed of a motor vehicle (step 301) that signal makes speed of vehicle detector 102 detection automobiles self, if the speed of a motor vehicle was less than for example 20km/ hour, then do not start any device, if the speed of a motor vehicle was greater than 20km/ hour (step 302), then set the receive frequency (step 303) of wave-receiver 103 according to the speed of a motor vehicle, the frequency values apart from signal that the value of setpoint frequency and wave emitter are sent has certain relation.That is, will divide seven the channels apart from signal of seven grades with corresponding wave emitter above 20km/ hour the speed of a motor vehicle, in the time of in the speed of a motor vehicle is in maximum one-level scope, be the frequency of the longest signal of transmitting range in the wave emitter with frequency setting.And the speed of a motor vehicle is when being in time in the big one-level scope, and frequency values is set at the frequency that transmitting range is the second long signal.Safe space between motorcars when the signal transmitting range of above-mentioned seven channels corresponds respectively to the speed of a motor vehicle at different levels, therefore, when the rear car apart from the distance of front truck during smaller or equal to the cooresponding safe space between motorcars of this speed of a motor vehicle, the receive frequency that micro controller system sets wave-receiver must receive this setpoint frequency apart from signal.That is this moment, car entered within the transmitting range of this correspondence speed of a motor vehicle setpoint frequency.At this moment, micro controller system 100 implements to car via footfeed controller and brake controller immediately after receiving the signal (step 304) of receiving setpoint frequency that wave-receiver 103 sent that restriction is refueled and brake (step 305).
Below, with the operation of explanation restriction oiling and brake.See also Fig. 7 and Fig. 8, when wave-receiver receives that micro controller system sets the signal of frequency, can start in brake controller and the footfeed controller device (not shown) drawing cables 41,51 such as motor.When cable 41 when pulled, brake arm 43 can be by drawing in the direction of arrow B, and then makes Brake pedal 42 to moving down, just like stepping on brake.In addition, when cable 51 when pulled, cable 51 can resist the power pulling clamping bar of spring 51 to hold the clamping bar 53a of device 53, makes the direction swing of clamping bar 53a towards arrow C, and then loosens and refuel cable 52.Under this state, though step on footfeed 55 still not stretchy refuel cable 52, thereby can't refuel.
As mentioned above, automatic collision-proof controller of the present invention is braked automatically and is limited oiling when detecting the speed of a motor vehicle and surpass the speed of a motor vehicle that the safe driving spacing limited, so can guarantee safety traffic.
Shown in the 4th figure, receipts wave point 103a, the 103b of wave-receiver 103 ... the arrangement mode of 103g is that the pairing receipts wave point of the short more channel of transmitting range 103a is configured in the place ahead more.That is the transmitting range of the receipts ripple channel of receipts wave point 103a is the shortest, and the transmitting range of the receipts ripple channel of receipts wave point 103g is the longest.Receipts wave point 103g is positioned at the most inboard interference (seeing also Figure 10) that can avoid the wave emitter of the automobile on other drawing lines of wave-receiver 103.In other words, the transmitting range that sent of the place ahead car 202 signal of long channel can't arrive the receipts wave point 103g of rear car 203 because of the influence of angle.
Embodiments of the invention system is that example is illustrated with the automobile, but is not limited to only be used on the automobile, and the present invention can be applied on all power actuated vehicles.
In addition, also can on clamper 53, install a hook 53b additional, during with convenient footfeed controller et out of order, make hook 53b hook the front end of clamper 53, make footfeed still can bring into play function.
In addition, can also in micro controller system 100, add formula,, step on heavily brake when approaching to 1 meter spacing even step on light brake when making two motor vehicles for example under 20km/ hour speed, approach to 2 meters spacings.
Though the present invention with a most preferred embodiment openly as above; but this is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; all can make some and change and retouching, so protection scope of the present invention should be looked the scope that claims define.
