Description
Technical field
The utility model is related to a kind of electric automobile brake assisted control system, more particularly to a kind of electric automobile intelligently to stop
Car assisted control system.
Background technology
Brake assisted control system is an important component of brake system on electric automobile, brake Power assisted control system
The performance of system directly affects brake system stability, so as to directly affect vehicle security energy.Conventional brake Power assisted control system
Uniting, it is intelligent well not have, and self-diagnostic function is not perfect enough, it is impossible to the state of enough real-time monitoring systems well.So one
The electric automobile brake assisted control system for planting intelligent, perfect self-diagnostic function high has application prospect well.
The content of the invention
In view of the problems of prior art, the utility model is there is provided a kind of electric automobile intelligent braking Power assisted control
System, with voltage detecting, current detecting, sensor detection, pipeline leakage detection function, concrete technical scheme is, Yi Zhong electricity
Electrical automobile intelligent braking assisted control system, including pressure sensor, brake assist controller, negative pressure pump, negative-pressure cup, its feature
It is：Pressure sensor, brake assist controller, negative pressure pump, unidirectional ring-type is serially connected negative-pressure cup successively, negative-pressure cup output
Negative pressure, brake assist controller warning output and access power supply are powered to pressure sensor, and negative-pressure cup is used to store negative pressure, pressure
Pressure in sensor detection negative-pressure cup is transmitted to brake assist controller, and brake assist controller controls negative pressure pump according to pressure value
Start and stop, it is ensured that negative pressure is within the specific limits；Brake assist controller detects the operating current of negative pressure pump in negative pressure pump work
And operating voltage, warning output is carried out beyond prescribed limit, the protection motor while motor is stopped；Pressure sensor when static
Signal piping leakage rate, warning output is carried out beyond certain limit.
Of the present utility model to have the technical effect that, voltage status, current status, sensor states, pipeline leakage state are automatic
Detection, the automatic alarm protection in normal range (NR) greatly improves the safety and stability of brake assisted control system, right
Vehicle power-supply system and negative pressure pump have good protective effect, improve the class of vehicle.
Brief description of the drawings
Fig. 1 is system block diagram of the present utility model,
Fig. 2 is workflow diagram of the present utility model.
Specific embodiment
It is described further with reference to example.
As shown in figure 1, electric automobile intelligent braking assisted control system, by brake assist controller, pressure sensor, bears
Press pump, negative-pressure cup composition, unidirectional ring-type is serially connected successively, and brake assist controller accesses power supply and supplied to pressure sensor
Electricity, the pressure in pressure sensor collection negative-pressure cup sends brake assist controller to, and brake assist controller is judged simultaneously
Starting or stoping for negative pressure pump is controlled, the pressure that negative pressure pump startup changes in negative-pressure cup makes its negative pressure required for producing, negative pressure
Brake assist system is directly fed, the change of negative pressure pressure inside the tank is gathered by pressure sensor and is transmitted to brake assist controller, stopped
Car assist controller judges and control starting or stoping for negative pressure pump；Judge voltage shape when the assist controller that brakes works
State, current status, sensor states, pipeline leakage state, warning output, difference report are carried out if any beyond normal range (NR) intrinsic parameter
Alert output different code.
As shown in Fig. 2 specific control method is comprised the following steps,
1）, system initialization；
2）, judge whether magnitude of voltage normal, no, negative pressure pump stops, brake assist controller output alarm 1, records failure
Code, the protection motor while motor is stopped is to carry out next step detection；
3）, judge that whether pressure value in the range of, is, negative pressure air pump inoperative is no, and negative pressure pump work carries out next step detection；
4）, judge whether current value normal, no, negative pressure pump stops, brake assist controller output alarm 2, records failure
Code, the protection motor while motor is stopped is to carry out next step detection；
5）, judge whether pressure sensor normal, no, negative pressure pump stops, brake assist controller output alarm 3, record
Failure code, the protection motor while motor is stopped is to carry out next step detection；
6）, judge whether pipeline normal, no, negative pressure pump stops, brake assist controller output alarm 4, records failure generation
Code, the protection motor while motor is stopped is the detection again for carrying out next round.
