Vehicle brake device
This vehicle brake device performs raising processing for raising, by a predetermined raising amount, the target hydraulic pressure of hydraulic fluid when the pressure of the hydraulic fluid starts increasing in order to suppress a delay in response to the increase in the pressure of hydraulic fluid during switching processing for gradually switching at least part of regenerative braking force to hydraulic braking force, and includes a judging portion which judges whether or not required braking force or deceleration is reduced during cooperative control; and a raising amount setting portion which during the raising processing, sets a second predetermined pressure as a raising amount if the judgement result of the judging portion is positive, the second predetermined pressure being smaller than a first predetermined pressure that is the raising amount when the determination result of the determination result is negative.

METHOD FOR OPERATING A VEHICLE BRAKE SYSTEM, AND BRAKE SYSTEM
A method for operating a vehicle brake system, wherein the brake system has at least one friction brake and at least one regenerative brake. A defined switching pattern is specified for switching between a self-cleaning operating mode for cleaning the friction brake and a normal operating mode of the brake system.

PRINTING APPARATUS, PRINTER SYSTEM AND METHOD FOR PRINTING ON AN OBJECT
A printing apparatus includes a transport device for moving an object to be printed-on through a printing region of the printing apparatus in a predefined transport direction. A first printing head is configured for depositing a viscous printing material, the first printing head being slidable along a first sliding axis, which is perpendicular to the transport direction, by a first printing-head moving apparatus. A second printing head is configured for depositing the viscous printing material, the second printing head being slidable along a second sliding axis, which is parallel to the first sliding axis and is offset in the transport direction, by a second printing-head moving apparatus. The first and second sliding axes can each be moved in the transport direction by a moving apparatus that is controllable by a control apparatus.
CONTROL APPARATUS FOR VEHICLE
A control apparatus for a vehicle determines whether to perform either of a first control and a second control. In the first control, power is transferred between a power supply facility outside a vehicle and a power storage apparatus during stopping of the vehicle. In the second control, power is transferred between a rotating electric machine and the power storage apparatus through an inverter during traveling of the vehicle. In response to the first control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a first limit value. In response to the second control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a second limit value. The apparatus sets at least either of the first and second limit values to a value suppressing decrease in drivability of the vehicle.
Automated Slip Detection on an Electronic Bicycle
An electronic bicycle includes a torque control system that controls what torque is applied to wheels of the electronic bicycle by electronic hub motors. The torque control system may determine a torque to apply to the wheels based on user input signals. The torque control system also may detect when the wheels of the electronic bicycle are slipping, and adjust the torque to minimize the time that the wheel is slipping. Additionally, the torque control system may determine a coefficient of friction between the wheels and the ground and determine a maximum torque to apply to the wheels based on the coefficient of friction. Furthermore, when braking, the torque control system may determine whether torque is applied to the wheels by passive braking or by active braking.
