Abstract: A method for, during creep mode, performing gearshift in a vehicle powertrain comprising a combustion engine, a gearbox, and a clutch is provided. The method comprises, in response to a request for gearshift, disconnecting the combustion engine from the gearbox by opening the clutch. The method further comprises, when the combustion engine is disconnected from the gearbox, shifting the gearbox and controlling the speed of the combustion engine to a target speed. Said target speed constitutes a combustion engine speed corresponding a desired combustion engine torque for completing a torque ramp during closing of the clutch. The method further comprises connecting the combustion engine to the gearbox by closing the clutch. A control device configured to perform the method and a vehicle comprising the control device are also provided.

Abstract: A method of controlling an engine and a transmission of a vehicle, which is a hybrid vehicle, includes the following steps that are carried out by a controller: determining whether the vehicle is under NCC (Neutral Coasting Control), determining whether an engine RPM reaches an engine RPM control point if it is determined that the NCC is in effect, determining an RPM and a gear stage of a vehicle transmission if it is determined that the engine RPM has reached the engine RPM control point, determining an engine target RPM of the vehicle, determining whether the engine RPM has reached a mild hybrid starter & generator (MHSG) control point, and controlling the MHSG according to a condition if it is determined that the engine RPM has reached the MHSG control point.

Abstract: A method of automatically activating a high-torque braking system in a heavy-duty vehicle configured to operate in at least one low speed, high torque mode and at least one higher speed, lower torque mode is disclosed. The method includes determining a speed-controller device such as a joystick or lever of the vehicle is in a first position which results in the vehicle travelling in a higher-speed, lower-torque mode, and, responsive to detecting braking and a change in position of the speed-controller from the first position to a second, neutral, position, activating a low-speed high torque mode of operation for braking the vehicle.

Abstract: A method for assignment of vehicle control includes receiving route data indicating a route between a starting location of a vehicle and a destination location, and determining an optimal vehicle configuration for the route based on a target vehicle speed and a hybrid torque split. The method further includes receiving a driver requested torque value and determining a passive pedal torque value based on the route data and vehicle powertrain data. The method further includes selectively assigning control of the vehicle to a vehicle system or to a driver of the vehicle based on the driver requested torque value and the passive pedal torque value.

Abstract: Systems and methods for transitioning a hybrid vehicle from park or neutral to drive or reverse are presented. In one example, a requested engine speed is adjusted in response to a transmission disengaging indication and a transmission disengaging timer when a transmission is being disengaged from a gear. In another example, the requested engine speed is adjusted in response to a transmission engaging indication and a transmission engaging timer when the transmission is being engaged to a gear.

Abstract: A vehicle includes an engine, an accelerator pedal, and a controller. The controller is programmed to command torque to the engine based on a set speed of adaptive cruise control and is programmed to, in response to the adaptive cruise control being active, a measured lateral acceleration of the vehicle exceeding a user-defined lateral acceleration threshold during a road curve, and the accelerator pedal being released, reduce a speed of the vehicle below the set speed until the measured lateral acceleration is less than the lateral acceleration threshold.

Abstract: A method for controlling a powertrain of a vehicle, the powertrain comprising:
an engine comprising mutually independently operable valves, the engine being configured to be operated in a four-stroke operation mode, and
a drivetrain comprising a transmission,
the method comprising:
while operating the engine in the four-stroke operation mode, identifying that a critical situation applies or is expected to apply, in which a fast downshift of the transmission is required,
initiating a downshift process in response to the identification of the critical situation,
during at least a part of the downshift process, increasing an engine speed by controlling at least the mutually independently operable valves of the engine such that the engine is temporarily operated in a two-stroke operation mode.-

Abstract: In the method and the apparatus for thermal management and control, and the vehicle according to the present disclosure, an overtemperature threshold of the vehicle may be adjusted in off-road conditions, and/or an operating temperature of the vehicle may be obtained, and driving parameters of the vehicle may be adjusted according to the operating temperature, so as to enhance the heat dissipation performance of the vehicle in the off-road conditions, and avoid that an over-temperature protection of the engine is easily triggered when the engine is operated at a high speed and a high torque in the off-road conditions, resulting in driving experience being affected by limited torque of the engine and turn-off of an air conditioning occurring in the vehicle, and driving safety also being affected, with no high-power fan and large-size radiator being additionally installed, and thus reducing weight and manufacturing cost of the vehicles.

Abstract: A transmission is subject to thermal management to prevent damage or failure due to overheating. Sensors can be employed to capture characteristics of a transmission, such as fluid temperature or pressure. Further, a predictive model can be invoked to predict characteristics based on current and future conditions. Characteristics can be compared with a threshold for intervention. A thermal mitigation strategy can be generated and initiated when characteristics satisfy the threshold. The thermal mitigation strategy can specify various actions to dissipate heat, including altering shift control logic and triggering mechanical devices that can increase airflow, reduce air temperature, or both surrounding the transmission.
