Description
Technical field
The invention belongs to automobile technical field, relate to automobile brake technology, especially a kind of EHB of pedal displacement ACTIVE CONTROL.
Background technology
Due to problems such as the exhaustion of oil and the destructions of environment, the advantages such as energy-saving and environmental protection make battery-driven car become the main direction of auto-industry future development.In order to improve energy utilization rate, economize on resources, protection of the environment; the auto-industry of various countries being are all are being researched and developed electronlmobil energetically; due to the restriction of motor, battery technology etc., the universal and commercialization that electronlmobil continual mileage is short, high these two problems of cost have hindered electronlmobil.
Composite brakig is normally comprised of a set of motor braking system and a set of hydraulic brake system.Due to high-power driving motor being housed on electronlmobil, so when car deceleration is braked, can utilize motor to drag and brake.The dragging of motor during simultaneously due to braking, by reverse power connection, produces inverse electromotive force, makes electrical motor change electrical generator into, generates electricity, and the kinetic energy of automobile is converted into electrical power storage and enters in storage battery, and regenerative brake or braking energy reclaim.The electric energy of these storages can increase the continual mileage of automobile in large quantities, changes electronlmobil continual mileage short, the shortcoming that battery size is large.In battery technology perfect not enough today, can greatly make up battery technology and be short of the problem of bringing.
Composite braking system is mainly divided into Das Gaspedal formula and brake pedal formula, and brake pedal formula is divided into again full decoupling composite braking system and decoupling zero composite braking system not.
Das Gaspedal composite braking system is as drive motor, to brake intrusion signal source by Das Gaspedal, and this system is changed less to original brake system, and it is convenient to control, but it does not meet the traditional braking pedal sense of chaufeur, and callable energy is also few.
Decoupling type composite braking system is not generally to load certain idle travel on original brake boost part, in this section of idle travel, by drive motor, provide regenerative brake power, after overcoming this section of idle travel, hydraulic braking gets involved, total braking force is provided together with regenerative brake, this composite braking system has retained the mechanical connection of pedal and hydraulic efficiency pressure system, reliability and safe, but its callable braking energy is few, has deviation with traditional brake pedal feel.
Full decoupling composite braking system belongs to EHB, the HAS hev system of Bosch company and the SCB system of TRW Ltd. (US) One Space Park, Redondo Beach CA 90278 U.S.A. all belong to full decoupling formula, its brake pedal and hydraulic efficiency pressure system do not have mechanical connection completely, generally to coordinate motor and pump to carry out ACTIVE CONTROL to the braking Input Forces of hydraulic efficiency pressure system by installation high-voltage energy storage, the braking energy of its recovery is many, braking response is fast, the accurately braking of identification of driver intention and simulation pedal sense, but high pressure accumulator technology is also immature, also there is hidden danger in reliability and safety, it has increased multiple electromagnetic valves and has also improved the difficulty of control and the risk of inefficacy in addition.
In EHB, with motor and physical construction, replace high pressure accumulator, pump, hydraulic tubing and electromagnetic valve, also can realize ACTIVE CONTROL and the adjusting of hydraulic coupling, by control path transmission of signal, promote master cylinder by motor driving device structure, between brake pedal and master cylinder, there is no hydraulic tubing, do not exist hydraulic tubing to reveal, high pressure accumulator potential safety hazard, the problems such as electromagnetic valve inefficacy, it is simple in structure, without master cylinder is changed, reduced cost, and the reliability of mechanical connection and safety are than full decoupling Shi Genggao, by ECU, directly control, be easy to realize ABS, TCS, ESP, the functions such as ACC.The composite braking system of this form has a bright future, and is the important developing direction of following brake system.
When the motor of master cylinder hydraulic pressure power driver module adopts the transmission device with self-locking, stressed when self-locking have a fluctuation, cannot reach good control effect by power control, therefore developed a kind of EHB of pedal displacement ACTIVE CONTROL, by treadle effort/pedal displacement graph of a relation of simulate ideal, give the good pedal sense of chaufeur, and can maximized recovery braking energy.
