摘要： A controller of an electric brake device includes first, second and third PKB operators. Upon receipt of an instruction to produce a parking brake active state while a parking brake is released, the first PKB operator exerts a braking force without depending on a brake pedal and determines if a desired braking force is exerted. After the determination by the first PKB operator, the second PKB operator makes a movable part ready to come into engagement with an engaged part and causes an electric motor to rotate in a direction in which the braking force is decreased, so that the movable part comes into engagement with the engaged part to prevent the rotation of the electric motor. Then, the third PKB operator produces the parking brake active state where no driving power is generated to the electric motor.

摘要： A vehicle brake system including: a pressurizing motor that is connected to a brake pedal and configured to increase a braking force that is generated; and a processor. The processor is configured with a program to perform operations including: operation as an information acquisition part to obtain information on whether a shift position of an automatic transmission is in a non-driving mode and information on operation on the brake pedal; and operation as a braking force controller to perform, when a predetermined retention condition is met, control of braking force so that a stationary state of a host vehicle is maintained. When the predetermined retention condition is met and the shift position is in the non-driving mode, the braking force controller is configured to perform control to increase the braking force that is generated using the pressurizing motor once the brake pedal is in a non-operated state.

摘要： A controller that controls behavior of a vehicle, and includes a control section that controls deceleration of the vehicle. In a situation where the vehicle is being decelerated, when a shift position of the vehicle is switched from a first position, at which power can be transmitted between a drive source (for example, an engine and a travel motor) of the vehicle and a drive wheel of the vehicle, to a second position, at which the power cannot be transmitted between the drive source and the drive wheel in an unlocked state of the drive wheel, the control section executes automatic deceleration control for automatically increasing the deceleration of the vehicle with respect to deceleration depending on a brake operation by the driver of the vehicle.

摘要： A method for controlling a maximum permissible pressure gradient of a power brake system of a motor vehicle. The method includes continuously calculating a maximum permissible pressure gradient, starting from a current motor speed gradient and motor speed of an external-force brake pressure generator, taking into account a predefined maximum permissible motor speed and a predefined maximum permissible motor speed gradient. In a next step, the maximum permissible pressure gradient is continuously transmitted to brake pressure demand units, so that, in the case of a braking event, the pressure gradient requested by the brake pressure demand units or resulting from a requested pressure is generally less than or equal to the maximum permissible pressure gradient.

摘要： A vehicle braking apparatus is adapted to a vehicle in which electric brakes are separately provided for wheels, and the electric brakes separately exert braking forces on the wheels. A braking force controller controls the braking forces separately exerted by the electric brakes. A first pair of electric brakes are provided for a front-left wheel and a front-right wheel, and a second pair of electric brakes are provided for a rear-left wheel and a rear-right wheel. At least one of the first pair of electric brakes or the second pair of electric brakes are multiphase electric brakes, and each of the multiphase electric brakes includes a multiphase motor having three or more phases. The braking force controller executes an up-down process to prevent a current from being concentrated on a particular phase of the multiphase motor, except when the vehicle satisfies a predetermined exemption condition.
