A method for controlling a vehicle includes monitoring the vehicle speed for a first threshold in conjunction with a driver request for negative torque, after which the method comprises increasing a friction braking ratio. The method further comprises monitoring the speed of the vehicle for a second threshold, wherein the second threshold is lower than the first, after which the method comprises solely using the friction braking for braking holding torque.

An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.

An agricultural vehicle-trailer-combination includes a traction vehicle including an engine and at least one ground engagement mechanism. A trailer is coupled to the traction vehicle. A service brake is operably controlled by the engine to brake. The combination includes a sensor and a control unit disposed in communication with the sensor, wherein a slip or a slip gradient on the ground engagement mechanism is sensed between the ground engagement mechanism and the ground surface. A trailer brake disposed on the trailer is adjustably controlled by the control unit. The trailer brake is adjustably controlled when the service brake of the traction vehicle is actuated, and the trailer is braked by the trailer brake as a function of the slip or the slip gradient when the slip reaches or exceeds a predeterminable slip braking value or the slip gradient reaches a predeterminable slip gradient braking interval.

A method for determining a slope of a roadway on which a vehicle is located includes imputing image data, supplied by an image sensor, pertaining to surroundings of the vehicle, identifying a defined reference object in the surroundings of the vehicle using the image data, determining an angle relationship between the reference object and the surroundings, estimating a slope of the roadway with reference to the determined angle relationship, and generating a signal indicative of the slope of the roadway. A device for determining a slope of a roadway on which a vehicle is located is configured to execute such a method.

An all-terrain vehicle may include a frame and a plurality of ground-engaging members supporting the frame. The all-terrain vehicle may further include a powertrain assembly supported by the frame and shiftable transmission supported by the frame and operably coupled to the powertrain assembly. The all-terrain vehicle may also include a display, a back-up camera, and a controller supported by the frame. The controller may be configured to receive a signal from the shiftable transmission corresponding to the shiftable transmission being in a gear of the plurality of gears other than a reverse gear. Further, the controller may be configured to determine the all-terrain vehicle is moving backwards and send an activation signal to the back-up camera to display images of the back-up camera on the display.

A method for controlling a separating clutch in a power train of a vehicle having a drive motor and a retarder. The clutch is arranged such that a rotor of the retarder is switched into a drive connection with the motor and/or power train via the clutch and a working chamber of the retarder can be filled with an operating medium to build up a braking power such that braking torque is exerted by the retarder onto the power train and/or motor. A control system switches the clutch into a closed or an open position. The switching of the clutch into the closed position occurs depending on an input signal to the controller, and the clutch is switched back into the open position depending on essentially no medium being present in the working chamber of the retarder and that predetermined limits of an operating and/or environmental parameter are not exceeded.

A vehicular breaking force control system that includes a control device including a processor that acquires a plurality of longitudinal accelerations from a driving assistance system, and calculates a driving/braking request when the vehicle is in a coasting state in which an acceleration operation or a deceleration operation are not performed during running of the vehicle. The processor further acquires a driving force lower limit set for a powertrain actuator having a set gear ratio, and distributes the driving/braking request to at least one of (i) a powertrain system including the powertrain actuator and (ii) a brake system including a brake actuator. The driving/braking request is distributed to the at least one of the powertrain system and the brake system based on the acquired driving force lower limit.

An electric parking brake system includes a wheel driven by an electric motor to move a vehicle, a parking brake maintaining the wheel stopped, a parking brake actuator operating the parking brake, and a drive controller controlling the parking brake actuator. The drive controller controls the electric motor to maintain the wheel of the vehicle stopped while the vehicle is parked, and calculates a parking torque based on a control amount of the electric motor that maintains the wheel stopped. The drive controller calculates a necessary braking force for the parking brake to maintain the wheel stopped based on the calculated parking torque, and controls the parking brake actuator so that the necessary braking force is generated.
