Row control realizes service brake eventually by wheel cylinder and brake.Parking braking part switchs acquisition driver by EPB
Parking be intended to, pass through EPB control sections and control EPB motors, deceleration and executing agency, perform clamp and realize parking function.
Reduce a controller, part harness, connector and installation space on hardware, reduce cost.Since only there are one ESC
Controller, input and output (sensor, the switch, motor etc.) hardware driving for being related to line traffic control electronic parking are all integrated in ESC controls
On device, therefore technically, EPB line traffic control electronic parking functional software is equivalent to a functional unit of ESC system, passes through ESC
The various responses and request of the Host master machine control units processing each functional unit of line traffic control electronic parking of software.
The utility model merges electronic stability control (ESC) with electronic brake controller (EPB).It is existing
ESC, mostly using mutually independent control system, mounted on the different position of vehicle, is led to EPB products by CAN bus
The two is merged by letter, the present invention, that is, incorporates line traffic control parking braking and electronic stability controls two big functions, public same
Control unit is covered, complexity, cost is reduced, improves security.Meet the integrated trend of chassis electric-control system.
Independent electronic parking controller has been integrated into ESC electronic stabilities control controller by ECU hardware, is added big
The circuit and electronic device of amount, in order to ensure that ESC controllers are assembled with the entirety of HCU, controller architecture size can not be arbitrary
Expand, therefore ECU hardware is while function and performance reliability is ensured, by optimizing circuit, device layout and whole cabling
It is combined the optimum optimization for realizing ECU performances and structure.
The utility model realizes following function：
1st, the complete function of line traffic control parking braking control is realized
Line traffic control parking braking control can be realized：
(1) static pull-up：When vehicle is in static schema, under normal circumstances, driver's pull-up EPB is opened supply voltage
It closes, EPB actuators will realize parking function automatically.
(2) static release：When vehicle is in static schema, supply voltage under normal circumstances, ignition switch ON grades, step on
Lower brake pedal, driver only need to gently press EPB switches, EPB actuators will realize release function automatically.
(3) automatic pull-up：Supply voltage is normal, ignition switch is at OFF grades, and EPB is by automatic parking.
(4) automatic release：When EPB perceives start assisting when driver has the intention of driving, automatic release.
(5) intelligent pull-up：Parking power will be changed according to the different gradient EPB of road automatically.
(6) dynamic pull-up：When brake pedal fails or is stuck, speed is more than 1.4m/s, and driver can grow drawing and stay
Vehicle button, EPB apply different brake force (imitative ABS algorithms) according to different coefficient of road adhesion and realize that urgent pressure is dynamic.
(7) stepping up：After system detects the decline of parking power after if EPB is tensed, EPB will apply parking power again,
To increase parking torque.
2nd, the complete function of electronic stability control ESC is realized
