See again Fig. 1: total power switch 1 is serially connected between the sub-SB1 of positive terminal and line-internal positive source node Q+ of direct supply V.The sub-SB2 grounding jumper of the negative terminals GND of direct supply V.The common port SP1 of speed per hour inductive switch 2 connects positive source node Q+, between the open contact of speed per hour inductive switch 2 and ground wire GND, is connected in series distance apart from the coil of selective relay 3; The far and near common port KA1 apart from selective relay 3 connects positive source node Q+, the common port SP2 of the far and near normally closed contact closure switch 4 apart from selective relay 3, and the far and near open contact apart from selective relay 3 connects the positive supply input end of long distance radar probe 6.The negative supply input end of the negative supply input end of the negative supply input end of forward direction low coverage radar probe 5, long distance radar probe 6, backward low coverage radar probe 7 and the negative supply input end grounding line GND of radar inductive switch 8.Indicator lamp 13 is serially connected between positive source node Q+ and ground wire GND.
The normally closed contact of direction switch 4 connects the positive supply input end of forward direction low coverage radar probe 5, and the open contact of direction switch 4 connects the positive supply input end of backward low coverage radar probe 7.
Forward direction low coverage radar probe 5 provides first group of control signal to radar inductive switch 8; Backward low coverage radar probe 7 provides second group of control signal to radar inductive switch 8; Long distance radar probe 6 provides the 3rd group of control signal to radar inductive switch 8.
The common port SP3 of the normal open switch in radar inductive switch 8 connects positive source node Q+, and open contact is communicated with normally closed inductive switch 9 common port SP3; The normally closed contact of normally closed inductive switch 9 is communicated with coil one end of brake relay 10, coil one end of the other end connecting time relay 11 of this coil, the other end grounding jumper GND of the coil of time relay 11.
The common KA2 of brake relay 10 connects positive source node Q+, the open contact of brake relay 10 relays is connected with the common port KT1 of time relay 11, is connected in series the coil of push-pull electromagnet 12 between the moving contact of time relay 10 and ground wire GND.
During use, open total power switch 1, circuit enters mode of operation.Indicator lamp 13 is lighted.Now, if the pin of chaufeur is placed on brake pedal, often open inductive switch 9 in off-state, the operation that this controller can not brake to brake pedal.Otherwise, if the pin of chaufeur is not placed on brake pedal, often open inductive switch 9 in closure state, the operation that this controller can brake to brake pedal automatically.
Under the state that can automatically brake to brake pedal at this controller, if the speed per hour of vehicle is lower than 20km/h, speed per hour inductive switch 2 is in off state, far and near do not have electric current to pass through on the coil of selective relay 3, this relay 3 common port KA1 through the common port SP2 of normally closed contact closure switch 4.When vehicle travel backwards, its gear controller is in reverse, and the common port SP2 of direction switch 4 is communicated with open contact, and positive source node Q+ is to the positive supply supplying power for input end of backward low coverage radar sensor 7, and backward low coverage radar probe 7 works.Otherwise vehicle is to overtake time, this gear controller is in other gears outside reverse, and the common port SP2 of direction switch 4 is communicated with normally closed contact; Positive source node Q+ is to the positive supply supplying power for input end of forward direction low coverage radar sensor 5, and forward direction low coverage radar probe 5 works.The ranging coverage of forward direction low coverage radar sensor 5 and backward low coverage radar sensor 7 is all 2.5 meters (this ranging coverage is adjustable), when that working in them detects and has obstacle (particularly by mistake phenomenon of taking throttle as brake being stepped on) in 2.5 meters, just to the corresponding control signal of radar inductive switch 8 output, make the normal open switch in radar inductive switch 8 closed, positive source node Q+ is to the coil of brake relay 10 and the coil power supply of time relay 11, the open contact and the positive source node Q+ that control brake relay 10 connect, the common port KT1 of elapsed time relay 10 and moving contact are to the coil power supply of push-pull electromagnet 12 again, the iron core action of push-pull electromagnet 12 makes brake pedal emergency action, emergency brake of vehicle, automobile is come to a complete stop or reduce impact, people's safety is taken in protection.
Under the state that can automatically brake to brake pedal at this controller, if the speed per hour of vehicle is more than or equal to 20km/h, speed per hour inductive switch 2 is in closure state, far and near have electric current to pass through on the coil of selective relay 3, positive source node Q+ connects the positive supply supplying power for input end of long distance radar probe 6 by the common port KA1 of this relay 3 through open contact, long distance radar probe 6 works.The ranging coverage of long distance radar probe 6 is 5 meters (this ranging coverage is adjustable), (the driver tired driving particularly that has obstacle in 5 meters when long distance radar probe 6 detects, divert attention) time, just to the corresponding control signal of radar inductive switch 8 output, make the normal open switch in radar inductive switch 8 closed, positive source node Q+ is to the coil of brake relay 10 and the coil power supply of time relay 11, the open contact and the positive source node Q+ that control brake relay 10 connect, coil power supply at the common port KT1 of elapsed time relay 10 and from moving contact to push-pull electromagnet 12, the iron core action of push-pull electromagnet 12 makes brake pedal emergency action, emergency brake of vehicle, by car deceleration or come to a complete stop, avoid knocking into the back or colliding.
During the self-actuating brake of this controller, the brightness of indicator lamp 13 reduces, and prompting has entered self-stopping state.When forward direction low coverage radar sensor 5 or backward low coverage radar sensor 7 or long distance radar sensor 6 have signal output always, 10 adhesives always of brake relay, time relay is automatic cutout (time delay 5-20 is adjustable second) after 11 time delay one end times, cuts off the power supply of push-pull electromagnet 12 coils.In addition, surveillant's pin is stepped on brake pedal, after artificial brake, also can automatically terminate the self-actuating brake of this controller.
The above, be only the utility model preferred embodiment, with this, do not limit the scope that the utility model is implemented, and the equivalence of doing according to the technical solution of the utility model and description changes and modifies, and all should belong to the scope that the utility model is contained.
