  • Publication number: 20090026835
    Abstract: The first control is to displace the primary piston by the amount obtained by multiplying the input rod displacement quantity by a proportional gain. The second control is to propel the primary piston by a prescribed offset thereby executing the first control. The third control is to displace the primary piston by the amount obtained by multiplying the input rod displacement quantity by a proportional gain specifically at a pressure decrease request. The brake force control device properly selects a control method from the first to third control methods to control the primary piston based on the automatic braking release conditions and a driver's brake request when a driver executes a brake operation during the automatic braking.

  • Publication number: 20080106142
    Abstract: In a brake control device using a plurality of low-noise and low-vibration pumps, if one pump fails, when the other pump compensates the function of the failed pump to reduce the influence of the failure, there is fear that a driver is not aware of the failure in the brake control device or neglects and leaves the failure unrepaired even if the driver becomes aware of the failure. The invention effectively causes the driver to be aware of the occurrence of a failure in the brake device while continuously ensuring brake force. If a failure is detected, hydraulic pressure actuators are controlled so that the pulse of hydraulic pressure in wheel cylinders becomes larger than that before the failure is detected. Alternatively, two pumps different in pulse characteristic of discharge hydraulic pressure from each other are connected in parallel to the wheel cylinders.

  • Publication number: 20080054718
    Abstract: Even in the case that at least one braking force generating function fails, it is possible to secure a maximum braking force as well as suppressing a yaw moment generated on the basis of the failure as much as possible even at a time when whatever braking force is requested, A target braking force to a normal brake apparatus is calculated on the basis of a result of detection by a malfunction detecting portion, in such a manner that a total of braking forces generated in the brake apparatuses in respective wheels becomes as equal as possible to a requested braking force, at a time when a malfunction is generated in the brake apparatus or a braking force control portion.

  • Publication number: 20080048491
    Abstract: A brake control system includes a plurality of fluid channels communicating from a hydraulic pressure source to a reservoir for controlling brake hydraulic pressures supplied to respective brake calipers by a plurality of hydraulic pressure control valves arranged in the respective fluid channels, wherein valve drive circuits for controlling the hydraulic pressure control valves are provided, two power relays for supplying power are connected to the plurality of valve drive circuits and when all hydraulic pressure control valves arranged in one fluid channel are normally open valves which communicate the hydraulic pressure source to the reservoir when nonenergized, different power relays are used for at least two valve drive circuits in the valve drive circuit corresponding to all the hydraulic pressure control valves to thereby prevent a malfunction of one power relay from causing all brake hydraulic pressures to fall.

  • Publication number: 20070222284
    Abstract: At least one of first and second actuator driving devices is supplied with electric power securely. When failure occurs in any one of main power line, auxiliary power line, first and second power supply lines and first and second relays, the first to third relays are controlled to be opened and closed so that failure part is separated or failure part is isolated from part where failure does not occur or supply of electric power to failure part is cut off or electric power is supplied to part to which electric power cannot be supplied.

  • Publication number: 20060028060
    Abstract: When the theft occurs, all wheels of an automobile or one wheel or more is mechanically locked to prevent the self-running theft or the tow-theft. There are used a theft detection unit which detects the theft based on the detection of the states of the various doors opening, the vibration of the vehicle body, the unlocking by using something except the regular key, the engine starting in the unlocked state, a braking force control means which locks all wheels or one wheel or more based on a signal from the theft detection means, and a braking force generation means which mechanically holds braking force while locking. When the theft occurs, all wheels or one wheel or more are locked.
