Complete or predominant use of regenerative braking in electric motorcycles rather than hydraulic braking may lead to brake discs and pads that are below an optimum operating temperature. To reduce the risk of accident, an indicator warns motorcycle riders that the brakes are below optimum operating temperature. With this knowledge, riders are prepared to apply extra braking force when slowing down, particularly in an emergency situation. Relative application of the regenerative brake and hydraulic brakes may be controlled to raise the temperature of the brakes so that they are primed.

A brake system for controlling the brake performance of a vehicle includes a brake, a control unit connected to one or more external condition sensors, and one or more brake performance sensors. The external condition sensors obtain parameters regarding conditions surrounding the vehicle, which are monitored by a driver assistance unit to estimate a probability value that the brakes should be applied to avoid a collision. The brake performance sensors obtain parameters regarding conditions of the brake. The control unit receives the obtained parameters from the external condition sensors and the estimated probability value and determines a surrounding threat level of the vehicle. The control unit receives the obtained parameters from the brake performance sensors and determines a brake performance level, and heats the at least one brake if the brake performance level is below a first level and the surrounding threat level is above a second level.

A method for operating a brake system for a motor vehicle, wherein the brake system has a braking pressure source and at least one wheel brake which can be pressurized with a braking pressure which is provided by means of the braking pressure source and acting on a brake piston. For performing a diagnosis of the brake system, the wheel brake is pressurized with a braking pressure which corresponds to a diagnosis braking pressure and which applies a certain force on the brake piston, and a counterforce directed oppositely to said force is applied to the brake piston.

The disclosure relates to a method for operating a braking assembly of a motor vehicle, in which a first hydraulic braking system is operated as a function of a target deceleration. A second electromechanical braking system can be activated for decelerating the motor vehicle.

The brake system also includes one or more processors in electronic communication with the valve, the one or more pressure transducers, and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the brake system to determine the stack closure pressure of the brake stack.

A method for compensating for excessively low actuating dynamics of a mechanical brake of a transportation vehicle, wherein a dividing unit receives a predefinition for a target overall retardation of the transportation vehicle and determines a mechanical target braking torque based on the target overall retardation and signals the same to the mechanical brake. The dividing unit predicts a mechanical actual braking torque of the brake by a model of the brake actuator and, based on the predicted mechanical actual braking torque, by activating at least one predetermined transportation vehicle component that is different from the mechanical brake, to generate a compensation torque, by which a control deviation which results when adjusting the mechanical actual braking torque to the mechanical target braking torque is compensated and the target overall retardation results in the transportation vehicle.

In a vehicle, application of hydraulic pressure in a hydraulic braking device is started, when an accelerator is turned on, and the accelerator is predicted to be turned off, and engine braking feeling is predicted to become insufficient, the engine braking feeling being deceleration feeling given to a driver when the accelerator is turned off and an engine brake is operated, and a predetermined condition that prediction time until the accelerator is turned off is shorter than dead time of a hydraulic pressure response of the hydraulic braking device is established. The hydraulic braking device generates a negative jerk in the vehicle when the accelerator is turned off upon lapse of dead time after application of the hydraulic pressure in the hydraulic braking device is started.
