A braking system for a vehicle includes a hydraulic vehicle brake with an electric actuator and an electromechanical braking device. The braking system further includes a locking mechanism configured to lock the electric actuator.

An electronic control unit (ECU) is disclosed. The ECU may detect an emergency stopping event associated with a vehicle. The ECU may determine, based on detecting the emergency stopping event, that electro-hydraulic brakes of the vehicle are in a disabled mode. The ECU may determine, based on determining that the electro-hydraulic brakes are in the disabled mode, a position of a brake pedal of the vehicle. The ECU may override, based on the position of the brake pedal, the disabled mode to engage the electro-hydraulic brakes during the emergency stopping event.

A hydraulic system of a vehicle includes a hydraulic pump with variable delivery capacity. The hydraulic pump is controllable as a function of a load and operatively connected to a drive of the vehicle. The system includes a first brake system for reducing a speed of the vehicle by at least one friction brake, and a permanent brake system being independent of the first brake system and configured to reduce the speed of the vehicle. The permanent brake system includes a first retarder circuit which cooperates with the hydraulic pump such that kinetic energy is removed from the vehicle by the permanent brake system via the hydraulic pump in order to decelerate the vehicle.

The device object of the present invention consists in two sets of photoelectric cells installed at front and rear of trucks and automobiles and in general moving vehicles.

It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

A comprises a vehicle control unit, VCU, and a control module, CM, configured to control the torque actuators. The VCU is configured to send to the CM a parameter request and a desired recuperation power or a desired parameter split ratio. If the CM determines that these are conflicting targets, then based on one or more predefined criteria, the CM will apply a parameter value and allocate a recuperation power or a parameter split ratio such that the applied parameter value is different from the requested one and/or the allocated recuperation power or parameter split ratio is different from the desired one. A method of controlling a wheel is also disclosed.

A coolant diverter system and method of controlling coolant flow are provided. The coolant diverter system includes a coolant diverter body having a coolant inlet opening, a driveline retarder outlet opening and a bypass outlet opening. The coolant diverter system also includes a valve positioned in the coolant diverter body. The valve is configured in a first valve orientation to fluidly couple the coolant inlet opening to the driveline retarder outlet opening in isolation from the bypass outlet opening. The valve is configured in a second valve orientation to fluidly couple the coolant inlet opening to the driveline retarder outlet opening and the bypass outlet opening. The coolant diverter system also includes a valve controller configured to place the valve in the first valve orientation in response to activation of a driveline retarder coupled to the driveline retarder outlet opening for braking.

A brake arrangement for a vehicle comprising a braking system arranged to vary hydraulic or pneumatic brake pressure that is arranged to apply a pressure to a brake caliper; an electric motor arranged to generate a braking torque that is applied to a first wheel when the electric motor is placed in a braking mode of operation, wherein the electric motor is arranged to vary brake torque generated when the electric motor is in the braking mode dependent upon a predetermined operating condition of the braking system.

The present specification relates to a system and a method for preventing overheating of an axle in a construction equipment. A system for preventing overheating of an axle in a construction equipment is mounted in the construction equipment and transmits driving power of an engine to a wheel, and the system includes: a brake pedal; a brake sensor which detects displacement of the brake pedal when the brake pedal is manipulated by an operator; an exhaust brake which is mounted in the engine and operates and controls an opening degree of an exhaust gas discharge passageway of the engine; and a control unit which adjusts the opening degree of the exhaust gas discharge passageway by controlling the exhaust brake corresponding to the displacement of the brake pedal when manipulation of the brake pedal is detected by the brake sensor.

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.
