A method for activating a parking brake function of a drum brake of a brake system of a vehicle, wherein a parking situation is taken into account in order to reduce the holding force to be exerted.

A vehicle starter aid system is provided for a vehicle having at least one driven axle and at least one non-driven axle. An electrically controllable brake system generates brake application signals as a function of input signals for the wheel brake actuators on the at least one driven axle. The inputs signals are received from a rotational speed sensor of the at least one non-driven axle and at least one signal-generator which generates signals which represent intended driving away of the vehicle from the stationary state and are different from the wheel rotational speed signals. An electronic brake control unit controls application of the wheel brake actuators of the at least one driven axle if the rotational speed signals of the rotational speed sensor correspond to zero wheel rotational speed and at the same time the signals of the signal-generator indicate the intended driving away of the vehicle.

A controller (104) and method for controlling torque generated by at least one traction motor (116a, 116b) of a vehicle (100) before a vehicle launch, comprising: means to determine that the vehicle is on a positive gradient; means to determine that the vehicle is prevented from roll-back by at least one vehicle brake (111); means to, in dependence on the determining that the vehicle is on a positive gradient and is prevented from roll-back, limit torque generation 10 by the traction motor in response to torque demand; and means to remove the limit when a vehicle launch condition is satisfied.

A vehicle control apparatus and a method for controlling the same are disclosed. The vehicle control apparatus includes an inputter, a determiner, and a controller. The inputter receives an automatic vehicle hold (AVH) switch operation signal from an AVH device, and receives a current vehicle movement value sensed by a sensing device and a current vehicle brake force value of a brake device that generates brake force in response to activation of the AVH device. The determiner determines whether the received AVH switch operation signal transitions from an ON state to an AVH entry state, determines whether vehicle movement occurs on the basis of the received current vehicle movement value during an AVH retention time in the AVH entry state, and determines that the current vehicle brake force value is in an abnormal state when vehicle movement occurs. The controller receives the current vehicle movement value and the current vehicle brake force value, and transmits a command for judgment to the determiner.

The invention relates to a method for carrying out a cleaning operation for at least one braking device of a braking system in a motor vehicle, said method having the following steps: setting a braking pressure by components of the braking device in accordance with a predefined braking pressure curve, wherein the braking pressure curve, during the cleaning operation, specifies braking pressures that vary over time for the braking device, correcting a setpoint motor torque that is to be provided by a drive motor of the motor vehicle and that is dependent on a braking effect brought about by the set braking pressure,
the predefined braking pressure curve being selected such that a longitudinal deceleration of the motor vehicle, which is brought about by the predefined braking pressure curve, can be compensated for by a corresponding additional motor torque.

An electric brake apparatus includes an electronic control unit (ECU) configured to move a power piston to cause a braking hydraulic pressure to be generated in a master cylinder by controlling an electric motor of an electric actuator based on an operation on a brake pedal (an input member position). A characteristic update processing portion of the ECU is configured to update, based on an operation amount of the brake pedal, characteristic data indicating a relationship between a hydraulic value transmitted from the ECU via a vehicle data bus and a movement amount of the power piston controlled based on the input member position, and store the updated characteristic data. The ECU is configured to control the electric actuator based on the updated characteristic data when an automatic brake instruction is input.

A drive unit includes a motor, a torque converter, a brake sensor, and a controller. A torque outputted from the motor is inputted to the torque converter. The brake sensor is configured to detect a braking operation amount. The controller is configured to execute a first control to control the torque outputted from the motor based on the braking operation amount.

A stability control system of a vehicle utilizing an electronic control unit that detects a yaw condition while each of the wheel brakes are actuated by EBCM and the wheel speeds are zero. An electronic control unit includes an electronic braking control module that controls actuation and de-actuation of vehicle brakes on an inclined surface. A yaw condition is identified while all vehicle brakes are actuated on the inclined surface and each wheel speed is zero. The electronic control unit identifies which uphill wheel is leading a direction of the yaw and identifies a wheel of an opposing axle diagonal to the identified uphill wheel. The electronic control unit in cooperation with the electronic braking control module de-actuates the vehicle brakes of the identified uphill wheel and diagonal wheel to increase a side friction to the identified diagonal wheels to reduce further yawing of the vehicle.

A remote start-up method of a manual transmission vehicle is provided. The method includes a parking braking force-associated remote start-up control that remotely starts-up an inclined parking vehicle parked on a ramp by confirming a situation where the parking braking force is maintained by a braking hydraulic pressure control of an electronic stability control (ESC) system in a remote start-up controller.

Provided are a vehicle, an electronic parking brake system and a control method thereof. The control method includes: controlling, when the electronic parking brake system is started, an electronic parking clamping force to be equal to a first preset value to perform parking braking on the vehicle; detecting the electronic parking clamping force and a current state of the vehicle; and when detecting that the vehicle moves, adjusting the electronic parking clamping force according to a magnitude relationship between the electronic parking clamping force and the first preset value to perform the parking braking on the vehicle again.
