摘要： A method for electronically controlling a brake unit having two brake systems in an automatically controllable vehicle combination includes inputting a request signal for automatic electronic activation of service brakes in a tractor vehicle brake system of a tractor vehicle and/or a trailer brake system of a trailer of the vehicle combination, wherein an automatically requested vehicle setpoint acceleration and/or an automatically requested vehicle setpoint velocity to be implemented by the respective service brakes are transmitted via the request signal. The method further includes monitoring and checking plausibility of the request signal to establish whether the automatically requested vehicle setpoint acceleration and/or the automatically requested vehicle setpoint velocity are or can be implemented completely or faultlessly by the respective service brakes. The method additionally includes outputting a trailer redundancy control signal at the trailer brake system under certain conditions.

摘要： An electric brake system includes a plurality of electric brake devices. A control device of each electric brake device includes: an abnormality determination section that determines whether there is abnormality in supply of power from a power supply device to the electric brake device; and a redundant function control section that, when the abnormality determination section has determined that there is abnormality in supply of power, controls the braking force by using an auxiliary power supply in accordance with a predetermined condition. The redundant function control section controls the braking force by using the auxiliary power supply at least when a desired braking force cannot be output even with all the electric brake devices for which the abnormality determination section has determined that there is no abnormality in supply of power, as the predetermined condition.

摘要： A vehicle braking force control device includes a braking force control unit. The braking force control unit is configured to shift to a drive state so as to use an auxiliary power source when a main power source fails, and to limit current outputted to an electric actuator of a braking device for producing braking hydraulic pressure when a transition is made to the drive state using the auxiliary power source. The braking force control unit has two current limit values used during actuation of the electric actuator by the auxiliary power source, the current limit values being a first current limit value for ensuring increased-braking-hydraulic-pressure characteristics, and a second current limit value for ensuring a necessary minimum braking hydraulic pressure, the second current limit value being less than the first current limit value.

摘要： A master cylinder generates master cylinder pressures in response to a brake operation by a driver on a brake pedal. A power hydraulic pressure generation device includes a pressure pump and an accumulator, and the accumulator accumulates an accumulator pressure increased by the pressure pump. A hydraulic pressure control valve device includes holding valves, pressure decreasing valves, and master cut valves for carrying out transmission of the master cylinder pressures from the master cylinder or the accumulator pressure from the accumulator. A stroke simulator is connected to a master pressure pipe via a simulator cut valve. The normally-open master cut valves and the normally-closed simulator cut valve for carrying out transmission of the master cylinder pressures mechanically generated by the master cylinder are backed up with backup electric power so that the operations continue even in the event of a change in state of electric power supply.

摘要： A brake control device for a brake system. The control device can perform both an interlocking brake control and an antilock brake control. The brake system includes a front-wheel hydraulic circuit, a front-wheel-side braking part; a rear-wheel hydraulic circuit, a rear-wheel-side braking part; and an electrically-operated pump which pressurizes the brake fluid. The brake control device includes a usual voltage mode where the interlocking brake control or the anti-lock brake control is performed when the supply voltage is a first voltage or more, and a low voltage mode where at least one of the interlocking brake control and the anti-lock brake control is performed in a limited manner when the supplied voltage is a second, lower voltage. An operation mode is changed from the usual voltage mode to the low voltage mode when it is determined that the supply voltage becomes lower than the first voltage.

摘要： An electromechanical braking system includes first and second electromechanical actuator controllers (EMACs) that each independently generate a complete set of drive control signals for an associated set of electromechanical actuators (EMAs). The drive control signals are generated in accordance with an antiskid algorithm to impart antiskid control to the braking of wheels associated with the EMAs. Drive signals for some of the EMAs from the set of EMAs are output by drivers of the first EMAC and drive signals for the other EMAs from the set of EMAs are output by drivers of the second EMAC. Drive control signals from one of the EMACs are used to control output the drive signals for all the EMAs from the set of EMAs, regardless of the EMAC in which the associated drivers are present. The drive control signals from the other of the EMACs are used as a backup set of drive control signals.
