Abstract
The invention discloses an emergency braking control method achieved through an electrical park brake. Under the emergency braking condition (for example, a brake pedal is blocked), after status information applied by a park brake switch is collected through an electrical park brake (EPB) system, a command is sent to a vehicle body electrical stable system (ESP) through bus communication, four wheels are braked at the same time through the ESP according to the deceleration value required by the EPB, and if one wheel of a vehicle is locked, the ESP can initiatively execute an anti-lock program. By means of the series of movements, safe and stable braking of the vehicle can be achieved, and person safety and vehicle safety are guaranteed.
Description
Technical field
The invention belongs to the technical field of chassis electric control braking Strategy Design, particularly a kind of emergency braking control method realized by electronic brake.
Background technology
Vehicle is when in case of emergency (such as brake pedal clamping stagnation) uses traditional mechanical parking brake to realize braking, owing to only applying larger braking force to two-wheeled below, often can there is rear lock thus produce vehicle whipping phenomenon, there is larger potential safety hazard.
Summary of the invention
In order to solve prior art Problems existing, the invention provides a kind of emergency braking method by electronics realization in braking, (the such as brake pedal clamping stagnation when emergency appears in brake system, vacuum booster fault), by identifying electronic brake (EPB, ElectricalParkBrake) controller master cock gathers emergency braking demand, and according to current braking system faults, order electronic stability program (ESP) adopts different braking methods to perform four-wheel hydraulic braking, realize fast, promptly, stable deceleration or parking, ensure the person and property safety.
Object of the present invention realizes by the following technical solutions:
A kind of emergency braking control method realized by electronic brake, it is characterized in that, when the speed of a motor vehicle is very high but emergency braking must perform, electronic brake controller realizes the short range safety and steady braking of vehicle under current working by performing following operation:
Vehicle-mounted computer receives the status information that EPB switch applies;
By sending bus command, brake command and braking deceleration angle value are sent to ESP;
ESP receives instruction and performs four-wheel hydraulic braking;
In braking ESP transmission simultaneously instruction, require that car body controller lights brake lamp;
If occur, certain takes turns locking situation, and ESP performs anti-lock program;
If chaufeur is stop EPB emergency braking function before 0km/h in the speed of a motor vehicle, then program exits;
If chaufeur applies EPB brake switch always, until the speed of a motor vehicle is 0km/h, then when the speed of a motor vehicle is 4km/h, EPB controller requires adapter braking, and while namely ordering ESP to reduce hydraulic braking force, EPB increases mechanical clamp braking force, until the speed of a motor vehicle is 0km/h;
Extinguish brake lamp, light the parking lamp in instrument;
Emergency braking action completes.
Feature of the present invention is: in an emergency braking situation (such as brake pedal clamping stagnation), gathered the status information of park brake switch applying by electronic brake system (EPB) after, order is sent to body electronics stabilization system (ESP) by bus communication, ESP can apply braking by the deceleration value of EPB requirement to four-wheel simultaneously, if vehicle is taken turns occur locking situation, ESP can initiatively perform anti-lock program, by above a series of actions, vehicle can realize safety and steady braking, guarantees the person and vehicle safety.
Accompanying drawing explanation
Fig. 1 is a kind of emergency braking sequential chart of the emergency braking control method realized by electronic brake.
Fig. 2 is a kind of diagram of circuit of the emergency braking control method realized by electronic brake.
Detailed description of the invention
EPB calculates the gradient by the longitudinal acceleration sensor be built in its computer, thus can calculate the sliding force that vehicle produces due to gravity on the slope, and computer applies braking force by motor to trailing wheel and balances sliding force, and vehicle can be stopped on the slope.When vehicle start, computer calculates by the size of the displacement pickup on pedal of clutch and throttle the braking force needing to apply, and is known the size of engine traction by high-speed CAN and engine computer communication simultaneously.The increase of the automatic calculation engine tractive force of vehicle-mounted computer, reduces braking force accordingly.When tractive force enough overcomes sliding force, computer drive motor brake off, thus realize the smooth and easy starting of vehicle.
Very high in the speed of a motor vehicle, but when emergency braking must perform, electronic brake controller realizes vehicle under current working, ensure safety and steady braking in shortest distance by performing following operation:
1, vehicle-mounted computer receives the status information that EPB switch applies;
2, by sending bus command, brake command and braking deceleration angle value are sent to ESP;
3, ESP receives instruction and performs four-wheel hydraulic braking;
4, in braking ESP transmission simultaneously instruction, require that car body controller (BCM) lights brake lamp;
If 5 occur that certain takes turns locking situation, ESP performs anti-lock program;
If 6 chaufeurs are stop EPB emergency braking function (unclamping EPB switch) before 0km/h in the speed of a motor vehicle, then program exits;
If 7 chaufeurs apply EPB brake switch always, until the speed of a motor vehicle is 0km/h, then when the speed of a motor vehicle is 4km/h, EPB controller requires adapter braking, namely while ordering ESP to reduce hydraulic braking force, EPB increases mechanical clamp braking force, until the speed of a motor vehicle is 0km/h, realizes steadily joining;
8, Systematical control extinguishes brake lamp, lights the parking lamp in instrument;
9, emergency braking action completes.
