A controller includes a SOC prediction unit to predict a SOC, based on a predicted result of a road grade and a vehicle speed in a scheduled travel route, and a discharge control unit to execute a discharge increasing control to previously increase a discharge quantity of the battery to prevent the battery from becoming in a saturation state based on a predicted SOC, when the battery becomes in the saturation state. The discharge control unit includes a first mode to execute an assist discharge increasing control in an assist travel, and a second mode to execute an EV discharge increasing control by decreasing the vehicle speed and by increasing an opportunity of an EV travel, as the discharge increasing control. When the EV discharge increasing control can be executed, the EV discharge increasing control is executed with priority relative to the assist discharge increasing control.

This work vehicle (tractor), which is provided with an engine and an accelerator pedal capable of changing the operational state of the engine, and is configured to be free to travel by means of an operation of the accelerator pedal by an operator, is equipped with a display near an operator's seat, said display being configured to be capable of displaying a screen (travel customization screen) for selecting whether or not to allow travel in conjunction with the accelerator.

Described herein is a method and arrangement of curve speed adjustment for a road vehicle (1). Obtained is data on: current ego velocity (v.sub.E), distance (d) and curvature (r) of an upcoming road segment, represented by a set of control points (P.sub.n, P.sub.n+1, etc.) to be negotiated; road property of a road comprising the road segment; environmental properties; and driver properties. The obtained data is continuously streamed to a data processing arrangement (12) arranged to perform a translation to target velocities (v.sub.road, n, v.sub.road, n+1, etc.) for the respective control points (P.sub.n, P.sub.n+1, etc.) and, for each respective control point (P.sub.n, P.sub.n+1, etc.), a translation from target velocity (v.sub.road, n, v.sub.road, n+1, etc.) for that control point (P.sub.n, P.sub.n+1, etc.) and distance (d.sub.n, d.sub.n+1, etc.) to that control point (P.sub.n, P.sub.n+1, etc.) and obtained current ego velocity (v.sub.E), to a target acceleration (a.sub.n, a.sub.n+1, etc.) to reach that control point (P.sub.n, P.sub.n+1, etc.) at its target velocity (v.sub.road, n, v.sub.road, n+1, etc.). The resulting target accelerations (a.sub.n, a.sub.n+1, etc.) are continuously streamed to a control unit (14) of the road vehicle (1) to adjust the road vehicle (1) acceleration to reach each respective control point (P.sub.n, P.sub.n+1, etc.) at its target velocity (v.sub.road, n, v.sub.road, n+1, etc.).

In some embodiments of the present disclosure, sensors mounted on a vehicle can allow opportunities for coasting to be predicted based on environmental conditions, route planning information, and/or vehicle-to-vehicle or vehicle-to-infrastructure signaling. In some embodiments of the present disclosure, these sensors can also predict a need for power and/or an end of a coast opportunity. These predictions can allow the vehicle to automatically enter a coasting state, and can predictively re-engage the engine and/or powertrain in order to make power available with no delay when desired by the operator.

A hybrid vehicle includes: an internal combustion engine; an electric motor; a controller; a transmission including an input shaft that receives power inputted from the internal combustion engine and the electric motor and an output shaft that outputs power to a drive wheel; and a clutch disposed in a first power transmission route between the internal combustion engine and the input shaft. The electric motor is connected to the input shaft so as to transmit power to the input shaft through a second power transmission route different from the first power transmission route. The controller changes the manner of controlling the electric motor upon switching of the state of power transmission from the internal combustion engine and the electric motor.

A vehicle propulsion system includes a transmission having manually selectable gear ratios, a manually operable clutch for selectively connecting the transmission to an engine for receiving torque from the engine and transmitting that torque through the transmission for propelling the vehicle, a clutch position sensor that generates a clutch position signal and a controller that is programmed to receive the clutch position signal, determine an actual engine output torque, determine an actual clutch torque capacity value based upon the actual engine output torque and the clutch position signal, determine a difference between the actual clutch torque capacity value and a clutch torque capacity from a torque to position table corresponding to the clutch position signal, determine an adjusted clutch torque capacity based upon the determined difference, and control an operation of the engine based upon the adjusted clutch torque capacity.

Data indicating current driving characteristics of a driver driving a vehicle can be received. A driving profile for the driver can be determined and categorized into a driving pattern category. A plurality of candidate travel routes for the driver to reach an intended destination can be identified. For each of the candidate travel routes a plurality of route segments can be identified. Based on the driving pattern category, a probability that the current driving characteristics of the driver will cause a traffic accident can be determined for each of the route segments. A route segment for which the probability that the current driving characteristics of the driver will cause the traffic accident is lowest can be determined and a notification can be communicated to the driver or vehicle indicating that route segment.

A method for mitigating clunk in a driveline of a vehicle system during a declutch event includes determining a current torque request of a prime mover based on an accelerator pedal position of an accelerator pedal of the vehicle system. The method includes determining a clutch pedal position and determining, via a controller, a clutch pedal speed based on a change of the clutch pedal position over time. The method further includes modifying, via the controller, the current torque request to obtain a modified torque request based on the clutch pedal position and the clutch pedal speed such that a stored potential energy in the driveline is minimized by a time that the clutch pedal of the vehicle system is disengaged during the declutch event.

When parking is expected at a predetermined point, state of charge reduction control is performed in a current trip to control an engine and a motor such that the state of charge of a power storage device when parking is expected at the predetermined point is lower than the state of charge of the power storage device when parking is not expected at the predetermined point. State of charge recovery control is then performed in a next trip to control the engine and the motor such that the state of charge is recovered during operation of the engine. Even when parking is expected at the predetermined point, execution of the state of charge reduction control is restricted in the case where the temperature of the motor is higher than a predetermined temperature.
