A vehicle brake system including a regenerative cooperative control device configured to control a regenerative brake device that applies a regenerative braking force to one of front and rear wheels and/or a friction brake device that applies a friction braking force to the front and rear wheels. After the regenerative braking force reaches an allowable regenerative braking force, the friction braking force applied to the other of the front and rear wheels is increased by the friction brake device up to a first friction braking force less than a braking force on an actual braking-force distribution line determined by the regenerative braking force at a time when it reaches the allowable regenerative braking force, and the friction braking forces applied to the one and the other of the front and rear wheels are subsequently increased so as to bring the friction braking forces close to the actual braking-force distribution line.

A method of controlling the vehicle may include predicting, by a controller, a braking situation of the vehicle; performing, by the controller, brake distribution control of front and rear wheels of the vehicle in a response to a predicted sudden braking of the vehicle at a predetermined level; and performing, by the controller, independent braking control of the rear wheels of the vehicle in a response to a predicted general braking of the vehicle at the predetermined level.

The disclosure relates to a method for determining a starting condition for cleaning a brake disk. A first step (S1) of this method determines that an amount of rust on the brake disk exceeds a defined threshold. Additionally, an energy quantity being necessary for removing the amount of rust from the brake disk is determined (S2). In a further step (S3), a distribution of brake energy over a current drive is estimated by using at least one parameter describing historic driving behavior and at least one parameter characterizing the current drive cycle. Subsequently, a starting speed and a starting brake force request is derived (S4). Additionally, a method for cleaning a brake disk is presented which comprises the determination of a starting condition for cleaning the brake disk by the method mentioned before. Moreover, a data processing device comprising means for carrying out said methods is explained.

A local control unit for a brake system is described. The control unit serves to actuate an electromechanical brake of the brake system of a wheel and according to one exemplary embodiment has a first connection for a main power supply and a second connection for a generator which is coupled to the wheel and which provides a standby power supply for the control unit.

A brake device applies a braking force to a vehicle by pressing a friction material against a rotor rotating integrally with a wheel. A temperature estimation method applied to the brake device includes: calculating an amount of absorbed energy absorbed by the rotor based on an amount of kinetic energy that the vehicle loses and an amount of potential energy that the vehicle loses during braking of the vehicle; and estimating a temperature of the rotor based on the amount of absorbed energy.

A method is provided for scheduling regenerative braking torque, comprising: sensing a position of an accelerator pedal; generating a torque request value in response to the sensed accelerator pedal position; determining a speed of operation of a motor/generator; determining a torque limit in response to the torque request value and the determined speed of the motor/generator; generating a regenerative braking command in response to the torque limit; and outputting the regenerative braking command to the motor/generator.

A rail-guided vehicle system connecting between vertically-spaced floors includes a descending rail to enable a travel vehicle to move downward. The descending rail has a helical structure and includes a rail in a first section where energy is generated when a brake included in the travel vehicle works and a rail in a second section where energy that has been generated when a travel vehicle traveled in the first section is consumed.

A method for controlling a vehicle includes automatically controlling vehicle brakes to decelerate the vehicle at a braking deceleration rate in response to an anticipated stop at a traffic signal and an adaptive cruise control system being active. The method further includes, in response to the vehicle decelerating to an intermediate speed, releasing the vehicle brakes. The intermediate speed is determined such that, at the intermediate speed, a coasting distance to a full stop is approximately equal to a distance to the traffic signal.

A drive source controller is configured to control a drive torque of a drive source that drives a vehicle. The drive source controller is configured to prohibit acceptance of drive source required torque from a cruise controller when automatic braking control is activated during cruise control, or not output the drive source required torque to the drive source controller when the automatic braking control is activated during the cruise control.
