摘要： Provided is an electric brake capable of accurately estimating the brake pad temperature and securing a sufficient braking force and response. An electric brake has a disc rotor rotating with a wheel, an actuator for rectilinearly actuating a piston in the axial direction of the disc rotor by using an electric motor, a drive controller for controlling the drive of the actuator, a brake pad pressed by the piston to give a frictional resistance to the disc rotor in the direction of rotation, and a braking start position detector for detecting a braking start position of the piston where the disc rotor is brought into contact with the brake pad. The drive controller stores the braking start position detected by the braking start position detector as the maximum braking start position. When the braking start position shifts in the pressing force-increasing direction, the drive controller updates the value stored as the maximum braking-start position.

摘要： The invention provides an electro-mechanical brake system which can keep a stop state even if a malfunction is generated in a parking brake, and an electro-mechanical brake apparatus used for the electro-mechanical brake system. An electro-mechanical brake actuator presses a brake pad to a disc rotor so as to independently brake a braking force of each of wheels. A parking brake is constituted by a pawl portion attached to a motor of a motor driving the electro-mechanical actuator and a latch. A main controller detects a failure of the parking brake on the basis of a motor displacement at a time of reducing a motor current, and increases the pressing force in the remaining normal parking brake in the case that the parking brake failure in one wheel or more is detected.

摘要： The solenoid current increases at low temperatures and decreases at high temperatures because the modulus of elasticity of an elastically deformable valve body and the slide resistance of an elastically deformable seal member vary with temperatures. Therefore the solenoid current for opening the valve mechanism from a closed position is required to be changed with low and high temperatures. To supply the solenoid current necessary for opening the valve mechanism without directly measuring the temperature, the solenoid current (the boost starting current leaning value) indicated when the pressure varies with the opening of the valve mechanism is recorded at the time of pressure-increasing, and thereafter when the valve mechanism is opened again after the closing of the valve mechanism, the solenoid current computed on the basis of the pressure-increase starting current learning value thus recorded is supplied.

摘要： An object of the present invention is to provide a forward collision avoidance assistance system that attains the reduction of driver's uncomfortable feeling and the improvement in drivability while ensuring the collision avoidance performance during operation for avoiding contact with an object.A collision avoidance calculation unit 3 determines a risk of collision between a host vehicle and an object detected in the host vehicle traveling direction based on information about the host vehicle detected by a host vehicle information detection unit 1 and information about the object detected by an object information detection unit 2, and calculates control information for object avoidance to be output to an actuator 5 based on a result of collision risk judgment. The collision avoidance calculation unit 3 uses a collision-avoidable limit distance Δxctl2 determined based on a physical limit that can avoid collision with the object, and a jerk-limited collision avoidable distance Δxctl1 determined based on the acceleration and jerk generated on the host vehicle by object avoidance movement, to control the brake force generated on the host vehicle by a brake actuator 5.

摘要： 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.

摘要： An electrically operated brake device in which braking force differences between electrically operated brakes are reduced to prevent unstable vehicle traveling during braking.Motors 13 of electrically operated brakes are returned to standard positions during the stop of a vehicle and the motor 13 of each of the brakes is driven for a predetermined amount, pressing a brake pad 17 against a disc rotor 18 to produce a braking force.An electric current value of each motor 13 in the above operation is measured and differences between the values are calculated. Electric current of each motor is increased or decreased so that there is no current difference between the motors 13. Based on a drive amount of each motor in this operation, standard positions of the motors are determined and updated. Repeating the above operations reduces braking force differences between the brakes.
