The present invention relates to an electronic control device for an automotive brake system comprising at least one interface to an operating element, in particular a parking brake actuation switch, and at least two actuating circuits for electric actuators, in particular electric parking brake actuators. According to the present invention, an electronic control device includes two or more independent processors directly connected to each other via a data bus.

Brake apparatus for automobile

본 발명품은 자동차용 제동장치(Brake apparatus for automobile)으로 페달을 밟고 놓음에 따라 전자석(1, 3)에 전압을 가해 자성을 띄게 해 금속 실린더(6)가 움직이게 한다. 금속실린더(6)는 유압장치(4)에 힘을 가하게 되고 이는 브레이크 디스크(2)에 압력을 전달하게 된다. 따라서, 유압장치를 부분적으로 사용해 저전압으로 동일한 제동력을 가질 수 있으므로 종래의 전자식 브레이크장치의 고전압으로 인한 위험부담을 줄일 수 있다. 또한, 기존의 유압식구조를 부분적으로 사용하기 때문에 종래의 브레이크 부속장치에 대한 호환성이 뛰어나다. 또한, 유압을 사용하지 않게 되므로 유압관련 장치를 효과적으로 줄일 수 있어 차량의 경량화가 가능하게 된다. 또한, 페달에서 브레이크까지의 동력전달 과정이 사라져 브레이크파이프의 필요성이 없어지므로 오일이 누수 되어 브레이크 기능이 상시될 일이 없다. 또한, 전자식 방식을 사용하므로 사람이 직접 브레이크를 작동시키는 방식보다 민감한 제동력을 가질 수 있다. As the pedal is depressed by a brake apparatus for automobile, the electromagnets 1 and 3 are magnetized by applying a voltage to the metal cylinder 6 so that the metal cylinder 6 moves. The metal cylinder 6 is subjected to a force applied to the hydraulic device 4, which causes pressure to be transmitted to the brake disc 2. Therefore, since the hydraulic device can be partially used and have the same braking force at a low voltage, the risk burden due to the high voltage of the conventional electronic braking device can be reduced. In addition, since the conventional hydraulic structure is partly used, compatibility with conventional brake attachment devices is excellent. In addition, since the hydraulic pressure is not used, the hydraulic pressure-related device can be effectively reduced, thereby making it possible to reduce the weight of the vehicle. In addition, since the power transmission process from the pedal to the brake is lost, the brake pipe is not needed, and the oil is leaked, so that the brake function is not stopped. In addition, because of the electronic system, it is possible to have a more sensitive braking force than a method in which a person directly operates the brake.

Method and apparatus for electromagnetically braking a motor

An electromagnetic braking system and method is provided for selectively braking a motor using an electromagnetic brake having an electromagnet, a permanent magnet, a rotor assembly, and a brake pad. The brake assembly applies when the electromagnet is de-energized and releases when the electromagnet is energized. When applied the permanent magnet moves the brake pad into frictional engagement with a housing, and when released the electromagnet cancels the flux of the permanent magnet to allow a leaf spring to move the brake pad away from the housing. A controller has a DC/DC converter for converting a main bus voltage to a lower braking voltage based on certain parameters. The converter utilizes pulse-width modulation (PWM) to regulate the braking voltage. A calibrated gap is defined between the brake pad and permanent magnet when the brake assembly is released, and may be dynamically modified via the controller.

Automotive electronic brake system and control method

본 발명은 차량용 전자 브레이크 시스템 및 그 제어방법에 관한 것으로, 특히 본 발명은 ABS 제어시, 후륜 좌우 바퀴사이의 휠 압력차가 생기는 경우, 후륜 좌우 바퀴사이의 휠 압력차를 최소화시켜 주행노면이 스플리트 노면으로의 변화한 것을 감지하지 못하더라도 차량의 스핀아웃을 방지하면서도 제동거리의 손실을 최소화한다. The present invention relates to an electronic brake system for a vehicle and a control method thereof. In particular, when the wheel pressure difference between left and right rear wheels occurs during ABS control, the road surface is split by minimizing the wheel pressure difference between the left and right rear wheels. Failure to detect changes to the road surface prevents the vehicle from spinning out while minimizing the loss of braking distance. 이를 위해 본 발명은 후륜 좌우 바퀴에 제공되는 마스터실린더의 브레이크압력을 조절하도록 각각 마련된 NO 밸브와, 이 NO 밸브에 소정의 PWM 듀티비를 제공하여 상기 NO 밸브의 개도량을 조절하는 펄스폭 변조부와, 이 펄스폭 변조부를 제어하는 제어부를 포함한다. 이 제어부는 ABS 제어시, NO 밸브의 개도량의 차이로부터 인식된 상기 후륜 좌우 바퀴의 휠 압력차가 소정값이면, 후륜 좌우 바퀴의 휠 압력차가 미리 설정된 범위를 유지하도록 상기 펄스폭 변조부를 통해 개도량이 큰 NO 밸브에 제공되는 PWM 듀티비를 현재 상태로 유지시킨다. To this end, the present invention provides a NO valve provided to adjust the brake pressure of the master cylinder provided to the left and right wheels, and a pulse width modulator for providing a predetermined PWM duty ratio to the NO valve to adjust the opening amount of the NO valve. And a control unit for controlling the pulse width modulator. The controller controls the opening amount through the pulse width modulator to maintain a predetermined range when the wheel pressure difference between the rear left and right wheels is determined to be a predetermined value during ABS control. Maintain the PWM duty ratio provided to the large NO valve.

Rotor brake and method for braking a rotor

The present application discloses a method of braking a rotor and a brake unit for braking a rotor disc. The brake unit comprises said rotor disc (100) rotatable about a central axis of rotation; a first brake pad mounting means (24') having a first end (24a') and a second end (24b') and a longitudinal outer, side, surface (24c') extending there between, wherein a first brake pad (22') is provided at said first end (24a') of said first brake pad mounting means (24') and positioned facing a first face of said rotor disc (100). The first brake pad mounting means (24a') comprises a first locking feature (28') provided on its outer, side, surface (24c'). The brake unit (10) further comprises first locking means (14') configured to pivot about an axis, the locking means (14', 14") being configured to be movable about said pivot axis so that a locking feature (14a) of said locking means (14') can come into contact with, or be moved away from said outer, side, surface (24c") of said first brake pad mounting means (24'). In a first position, said first locking means (14') is configured to be in contact with and engaged with said first locking feature (28'), to thereby prevent movement of said brake pad (22") towards said face of said rotor disc (100). In a second position, said first locking means (14') is configured to be disengaged from said locking feature (28') to thereby permit movement of said braking pad (22') towards said face of said rotor disc (100).

Transmission for vehicles with electromagnetic retarders

Pour réduire au maximum l'allongement d'une transmission de véhicule dû au montage en porte-à-faux d'un ralentisseur électrique (2, 3) à deux disques rotoriques (9) sur le carter de la boîte de cette transmission, on prévoit successivement, entre la bride de boîte (14) et le croisillon (33) du joint de cardan (15) le plus proche, un intercalaire tubulaire (23) et une bride de cardan inversée (24). Ces deux pièces sont appliquées l'une contre l'autre le long de collerettes extérieures qui forment un anneau (13) sur lequel sont montées axialement de part et d'autre les bagues (10) des deux couronnes rotoriques du ralentisseur. To minimize the elongation of a vehicle transmission due to the cantilever mounting of an electric retarder (2, 3) with two rotor discs (9) on the casing of the transmission box, we successively provides between the box flange (14) and the spider (33) of the nearest universal joint (15), a tubular insert (23) and an inverted universal joint flange (24). These two parts are applied one against the other along external flanges which form a ring (13) on which are axially mounted on either side the rings (10) of the two rotor rings of the retarder.
