摘要： A brake torque control device obtains inertia torque Tine based upon an equation of motion (Tine=Tw−Ft·Rt) about the rotation of a tire based upon a wheel torque Tw according to a brake torque exerted on the tire, road friction force Ft and a radius Rt of the tire. When the inertia torque Tine exceeds a predetermined reference value, road friction force Ft at this time is set as estimated maximum road friction force Fmax. The instructed brake torque is calculated under the condition that the value that is obtained by adding the predetermined value corresponding to the inertia torque Tine to the torque Fmax·Rt based upon this estimated maximum road friction force Fmax is set as an upper limit value of the instructed brake torque. This allows to clearly set, as one value, the target value of the instructed brake torque upon an ABS control, thereby being capable of more accurately executing the pressure-increasing control and pressure-reducing control of the brake fluid pressure.

摘要： A braking force control apparatus adapted to generate a braking force, which is larger than that generated in a regular case, when a predetermined braking operation is carried out, this apparatus aiming at preventing the occurrence of an unnecessarily large sensible deceleration during a low-speed travel of a vehicle. ECU (10) is adapted to judge whether or not an emergency braking operation has been executed on the basis of a master cylinder pressure (Pmc) and its rate of change (dPmc). When a judgement that an emergency braking operation has been carried out is given, a wheel cylinder pressure (Pwc) is quickly increased by supplying an accumulator pressure to the wheel cylinder. When a vehicle speed exceeds a predetermined level during the execution of the emergency braking operation, the wheel cylinder pressure (Pwc) is speedily increased (116, 118) by a braking assist regular control operation. When the vehicle speed is not higher than a predetermined level during the execution of the emergency braking operation, the wheel cylinder pressure (Pwc) is slowly increased (116, 120) by a braking assist starting special control operation.

摘要： The pressure supply valve (40) provides hydraulic pressure from a pressure source (20) to the system modulators (46, 46', 48, 48', 52, 52') and isolates a hydraulic boost chamber (34) of a boosted master cylinder (12). The pressure supply valve (40) includes an armature (83) operated piston valve (72) having a through opening (79), a valve seat (85) of the piston valve (72) engageable with a ball valve (68). The ball valve (68) normally prevents fluid flow from the pressure source (20) to the modulators (46, 46', 48, 48', 52, 52'), and the piston valve (72) permits fluid flow through itself during normal and adaptive braking. During traction control operation, the piston valve (72) displaces the ball valve (68) and permits the pressure source (20) to communicate with the modulators (46, 46', 48, 48', 52, 52').

摘要： When excessive acceleration slip of a driving wheel is detected by wheel speed sensors attached to driving and non-driving wheels, an electronic control unit provides first and second control signals to a change-over valve and a control valve, respectively. The change-over valve operates in accordance with the first control signal to supply hydraulic pressure from a hydraulic pump to control a cut-off valve to thereby cut off communication between a master cylinder and a wheel cylinder. At the same time, hydraulic pressure from the hydraulic pump is fed to the wheel cylinder through the change-over valve and the control valve to brake the driving wheel. The control valve operates in accordance with the second control signal to increase or decrease the pressure in the wheel cylinder thereby adjusting the braking force for the driving wheel.
