Abstract
The utility model relates to an intelligent braking system, which is provided with a speed sensor, a pedal acceleration sensor, a fuel-injector electronic control unit, a leveraged electromagnetic actuator, namely a braking actuator and a fuel-injection-pump oil-supplied stopping actuator in the existing system. The system has safety incomparable with the safety of the existing system. When the speed is smaller than 60 km/h, a driver can brake in mistakenly trampling an accelerator in emergency to avoid accidents. When the speed is larger than 60 km/h, the emergency brake and the accelerator realize respective functions.
Description
Technical field
The utility model relates to the brake system of automobile, particularly travels in the brake system of bustling urban district automobile.
Background technology
Along with science and technology development, various sensors, Vehicle radar, microprocessor, electron controls technology has obtained utilization widely on mechanical engineering technology and auto transport.
Automobile is as modern times a kind of transport facility of paramount importance, its safety is subject to people's attention always, 60 kilometers of the fixed city F-Zeros of traffic law, because new hand's chaufeur number is more and more and the complexity of urban road, emergency case forces emergency brake inevitable.Because now brake on the automobile and throttle be all by right crus of diaphragm control, in case run into accident, flurried in " throttle is mistakened as brake " be recurrent, this also is the one of the main reasons that causes the traffic accident generation.For fear of the generation of this type of accident, a intelligent braking system of automotive market active demand.Existing brake system mainly is based on radar ranging and stops by force, does not consider the factor of the speed of a motor vehicle or high-speed passing, can not solve " mis-accelerator pressing is when brake " and causes the problem of traffic accident.
Summary of the invention
The purpose of this utility model is that the urgent mis-accelerator pressing of chaufeur also can be realized the problem of brake function in the time of will solving the automobile speed that travels in the urban road less than 60km/h.Consider the different road conditions of urban road and express highway, during greater than 60km/h, chaufeur emergency brake and throttle are realized function separately at automobile speed.
The technical scheme that the utility model is taked is: installation rate sensor before microcontroller on the automobile, detect the moving velocity of automobile, the pedal acceleration pick-up that links with microcontroller is installed under throttle, this sensor can only be when violent step on the accelerator could output signal, in brake system a lever electromagnetic actuator that links with microcontroller being installed is brake actuating mechanism, between microcontroller and automotive engine, fuel injector electronic control unit is set, the stop control lever actr is installed in diesel injection pump inflow point.
Fuel injector electronic control unit is made of thyristor, normally closed contact, firing circuit power supply, relay, switch, resistance.
The stop control lever actr of installing on the fuel injection pump housing can adopt electromagnetic valve switch, also can adopt the control injection pump rack, or shuts down the handle method.
The beneficial effects of the utility model are:
(1) speed of a motor vehicle that detects when speed sensor is less than 60km/h, and the Das Gaspedal acceleration/accel that detects of pedal acceleration pick-up is during greater than specific value, and gas plays braking action;
When (2) moveing backward or travelling, radar detection is to there being obstacle, and the Das Gaspedal acceleration/accel that detects of pedal acceleration pick-up is during greater than specific value, and gas plays braking action;
When (3) travelling, radar detection is to there being obstacle, but the Das Gaspedal acceleration/accel that the pedal acceleration pick-up detects is during less than specific value, and the throttle of automobile and brake keep effect separately;
(4) when the speed of a motor vehicle of sensor greater than 60km/h, but the Das Gaspedal acceleration/accel that the pedal acceleration pick-up detects is during less than specific value, the throttle of automobile and brake keep effect separately.

The specific embodiment
Specified below in conjunction with accompanying drawing 1 and Fig. 2:
In Fig. 1, when automobile travels with the speed that is lower than 60km/h on highway, need emergency brake if run into emergency case, this moment, speed sensor was delivered to microcontroller with signal, when the driver when hiding that danger is wrong to be used as throttle brake and to floor, the pedal acceleration pick-up throttle under has signal and is sent to microcontroller, when two signals are just in time identical, microcontroller sends instruction, makes fuel injector electronic control unit work.Fuel injector electronic control unit.Force driving engine to quit work.Meanwhile, microcontroller sends instruction and gives brake actuating mechanism, and automobile brake system works rapidly, brakes.
In Fig. 2, when mis-accelerator pressing occurring when brake, the power on the Das Gaspedal of being applied to is much larger than 100N, the pressure switch sensor changes closure state into by normally open, thyristor (T) the control utmost point obtains the energizing signal conducting, drive the electromagnetic valve action of brake pedal draw gear, realize forced brake; Simultaneously, relay (J) adhesive of control fuel injector power supply disconnects two normally closed contacts (A), (B) that are connected the fuel injector power supply, has cut off the fuel injector power supply, forces driving engine flame-out immediately.Because the trigger characteristic of thyristor makes circuit be in self-locking state naturally.Even chaufeur reduces immediately or cancels the power that is applied on the Das Gaspedal, make the pressure switch sensor get back to normally open, still can not make system withdraw from the mandatory protection state, thereby prevent the generation once more of accident.
