Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination. Using a driver deceleration demand a pressure level and/or duration for a preliminary pressure peak to be provided in one or more fluid lines of the trailer brake system is determined. A trailer brake signal is generated for controlling the trailer brake system in accordance with the preliminary pressure peak.

A method for controlling a vehicle train, having a towing vehicle and at least one trailer vehicle. The towing vehicle includes a continuous deceleration device for performing a continuous deceleration. The method includes the steps: determining a trailer mass of the trailer vehicle in the prevailing vehicle configuration of the vehicle train; determining a towing vehicle trailer mass of the towing vehicle in the prevailing vehicle configuration; determining a mass ratio of the prevailing vehicle configuration based on the trailer mass and the towing vehicle mass; and limiting a maximum permissible continuous deceleration power of the continuous deceleration device based on the mass ratio. A driver assistance system is configured to perform the method. A commercial vehicle includes the driver assistance system. A computer program product is configured to perform the method.

Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination. A HMI component used by the operator to provide a deceleration input to the trailer brake system is identified. Based on this a pressure level to be provided in one or more fluid lines of the trailer brake system is determined. A trailer brake signal for is generated and output controlling the trailer brake system to provide the determined pressure.

Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle, comprising: determining a coupling force associated with a coupling point for providing a coupling between the vehicle and a trailer, determining, in dependence on the coupling force, the presence of a trailer coupled to the vehicle at the coupling point; and controlling one or more components of the vehicle in dependence on the determination of the presence of the trailer.

Systems and methods related to downhill target speed acceleration control are provided. A powertrain torque control system includes a logic device configured to detect a braking behavior to set a target speed of a vehicle to descend downgrade. The logic device is further configured to activate a downhill speed control of the vehicle based on the detected braking behavior. The downhill speed control may include applying powertrain torque feedback to limit an acceleration of the vehicle to hold the target speed of the vehicle while descending downgrade. Associated methods and vehicles are also provided.

The invention obtains a controller and a control method capable of improving operability of a straddle-type vehicle. In a controller 20 and a control method according to the invention, an execution section of the controller 20 executes a control mode in which vehicle speed control is enabled in response to a first trigger and the vehicle speed control is disabled in response to a second trigger. In the vehicle speed control, a vehicle speed of a straddle-type vehicle 1 is controlled on the basis of a target vehicle speed in the case where it is determined that the straddle-type vehicle 1 travels on a downhill road. The execution section executes the control mode on the basis of rotational operation information as information on a rotational operation to rotate an accelerator grip, which is located at a reference position in an unloaded state by a rider of the straddle-type vehicle 1 and changes drive power generated to the straddle-type vehicle 1 when being rotated within an angle range located in a first direction with the reference position being a reference, within an angle range located in a second direction as a reverse direction from the first direction with the reference position being the reference.

A computer system determines, by taking into account topography information of a stretch of road to be travelled by a vehicle, to which extent service braking can be applied before the service brake of the vehicle is expected to overheat upon travelling the stretch of road, and reserves an amount of energy to be stored in an energy storage system of the vehicle for allowing endurance braking of the vehicle to avoid causing overheating of the service brake. The amount of energy reserved is adapted to the extent to which the service braking is determined to be applied upon the vehicle traveling the stretch of road.

Systems, methods, and apparatuses are provided for controlling a braking torque of a vehicle while travelling in an at least semiautomated manner. Standstill data is received, while the vehicle is traveling in the at least semiautomated manner on an incline and/or a decline, when a temporary standstill of the vehicle is requested by the assistance system. Speed values are continuously received that describe a speed of the vehicle while the vehicle is decelerating prior to the temporary standstill. Slope data is continuously determined that describes an angle of the incline or decline. An amended speed value is continuously computed that depends on the speed value and the slope data. An electronic control signal is output to control the braking torque to bring the vehicle to the temporary standstill when the amended speed value decreases below a predetermined threshold value and the standstill data are received.

A method of outputting a notification in a driver environment of a vehicle is disclosed. The method comprises obtaining topographic data representative of the topography of an upcoming road segment, identifying an upcoming downhill slope in the upcoming road segment, obtaining, based on the topographic data, a speed estimate representative of a maximum allowable speed of the vehicle upon reaching the upcoming downhill slope for keeping the speed of the vehicle below a threshold speed in the upcoming downhill slope while using a predetermined braking amount of wheel brakes of the vehicle, and outputting a notification indicating the speed estimate in the driver environment before the vehicle reaches the upcoming downhill slope. The present disclosure further relates to a computer program, a computer-readable medium, a control arrangement, and a vehicle.
