    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.

    摘要: A method of assisting deceleration during a stop of a motor vehicle having a drivetrain including a traction motor, a road wheel operatively connected to the drivetrain, a friction brake configured to decelerate the road wheel, and an electronic controller includes detecting, via the electronic controller, a request to stop the vehicle. The method also includes commanding the traction motor to provide regenerative braking in response to the request to stop the vehicle. The method additionally includes determining a current vehicle operating state. The method also includes determining an amount of brake drag torque to be generated by the friction brake based on the current vehicle operating state. The method further includes commanding an application of the determined amount of the brake drag torque in parallel with the regenerative braking, thereby operating the friction brake as a mechanical drivetrain damper while assisting the regenerative braking to stop the motor vehicle.
