Below introduce in detail the workflow that above-mentioned dynamic brake control setup dynamic brake is controlled from three aspects, please in conjunction with Fig. 1 to Fig. 4.
1), parking system EPB2 request dynamic stabilization system ESP3 braking, dynamic stabilization system ESP3 response is braked.
In when, emergency situation occurring in Vehicle Driving Cycle need to stop, chaufeur step on brake pedal find pedal lost efficacy after pull-up handle 11 immediately, activate immediately dynamic brake after handle 11 pull-ups and control.The CAN module now be built on EPB controller 21 sends the dynamic brake request command by the CAN bus to ESP controller 31, after being built in another CAN module on ESP controller 31 and receiving this dynamic brake request command, by ESP controller 31, judge whether dynamic stabilization system ESP3 possesses the intervention condition.If ESP3 is idle condition, while possessing the intervention condition, by ESP controller 31, according to this dynamic brake request command, drive hydraulic pressure regulator to be built compacting to vehicle moving, until EPB controller 21 while no longer sending this dynamic brake request command pressure release exit.When EPB controller 21 stops sending the dynamic brake request command, EPB controller 21 is then got involved dynamic brake immediately, until vehicle stops fully.
2), parking system EPB2 request dynamic stabilization system ESP3 braking, dynamic stabilization system ESP3 can't get involved braking, by parking system, EPB2 is directly braked.
In when, emergency situation occurring in Vehicle Driving Cycle need to stop, chaufeur step on brake pedal find pedal lost efficacy after pull-up handle 11 immediately, activate immediately dynamic brake after handle 11 pull-ups and control.The CAN module now be built on EPB controller 21 sends the dynamic brake request command by the CAN bus to ESP controller 31, if now dynamic stabilization system ESP3 is getting involved work or et out of order and can't respond the braking request, directly by parking system EPB2, simulated the abs braking algorithm and braked, until vehicle stops fully.
3), failure mode, said failure mode refers to that the CAN bus node at dynamic stabilization system ESP3 et out of order and dynamic stabilization system ESP3 place closes here.
If the CAN bus node at dynamic stabilization system ESP3 et out of order and dynamic stabilization system ESP3 place is closed, parking system EPB2 will lose the communication with dynamic stabilization system ESP3.Thereby lose the wheel speed signal sent from dynamic stabilization system ESP3, parking system EPB2 can directly enter failure mode, directly by parking system EPB2, being simulated the abs braking algorithm is braked, until vehicle stops fully, reduce because vehicle continues the potential safety hazard of travelling and may cause.
In the control process of whole dynamic brake, only have handle 11 pull-ups on brake controller 1 could activate dynamic brake control, the input of brake pedal can not activate parking system EPB2 and dynamic stabilization system ESP3 carries out jointly controlling of dynamic brake.In other words, the input of brake controller 1 is only the unique input jointly controlled that parking system EPB2 and dynamic stabilization system ESP3 carry out dynamic brake.
It is pointed out that chaufeur is in normally travelling, if maloperation pull-up handle 11, chaufeur can obviously feel that vehicle enters braking mode, and release lever 11 is avoided car rear-end generation safety misadventure immediately.So, after maloperation pull-up handle 11, parking system EPB2 can pass through the state judgement of the signals such as safety strap, car door, wheel speed, switch misoperation if, just do not go to carry out any action, thereby guarantee the safety of driving.
When dynamic brake control setup of the present utility model is stepped on the inefficacy of brake pedal discovery brake pedal at chaufeur, as long as pull-up handle 11 just can activate immediately dynamic brake and control, thereby can avoid brake pedal in the Vehicle Driving Cycle process to lose efficacy and the generation of the problem of arrive vehicle generation whipping, sideslip or collision, improve the safety performance of car load.
The utility model also provides a kind of automobile, and above-described dynamic brake control setup is installed on described automobile.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
