A method for operating a drive-train of a vehicle, such as a municipal or agricultural utility vehicle, having at least one drive machine, a vehicle transmission with at least two gears, at least one drive axle and at least one auxiliary power take-off. The method includes controlling or regulating a supply of normal power from the drive machine as a function of a normal torque characteristic. Depending on the operating situation, supplying additional power to the at least one drive axle and/or to the at least one auxiliary power take-off. The supplied additional power is controlled or regulated as a function of operating situation dependent torque characteristics which are called up as a function of the selected gear at the time.

An integrated control apparatus for in-wheel system vehicle is provided. The apparatus includes a shift button for a shift control and a dial for a steering control which are assembled integrally to each other to form one integrated component. The apparatus provides a driver with vehicle information through an operation of the dial when the steering control is not performed, and eliminates a risk of accidents occurring due to a control error by configuring a shift control manner and a steering control manner to be different from each other.

Methods and controllers for controlling engine speed to reduce NVH that occurs in conjunction with transmission shifts are described. In some embodiments, when a transmission shift to a target gear is expected, a target engine speed appropriate for the target gear is first determined. A target rate of change of the engine speed is calculated from the initial engine speed and target engine speed in conjunction with a target transition time. A target torque is then calculated from the target rate of change of engine speed. A target firing fraction or induction ratio are determined that are desired for use with the target engine speed based on the target torque. The transition to the target engine speed and target firing fraction or induction ratio are completed before the gear shift is completed. The described approaches are well suited for use during skip fire or other cylinder output level modulation operation of the engine.

Since a maximum rotation speed of a second rotary machine is set to a lower value when a supercharging pressure is high than when the supercharging pressure is low, an engine torque decreases with an rotation speed of the second rotary machine which is relatively low and the rotation speed is less likely to fall into a high-rotation state. When the supercharging pressure is relatively low and the rotation speed is less likely to reach an upper-limit rotation speed of the second rotary machine, the maximum rotation speed is set to a relatively high value. Accordingly, the engine torque does not decrease to the rotation speed which is relatively high and power performance can be easily secured. As a result, it is possible to prevent a decrease in power performance due to the decrease in the engine torque and to prevent the rotation speed from falling into a high-rotation state.

A method for controlling an interference torque for a vehicle is provided. The method is applied to a new energy vehicle including an electric motor and an engine, and includes steps of: arbitrating between a pedal torque of a driver and an interference torque required by ESP; performing an initial allocation on the electric motor and/or the engine in response to the pedal torque when the vehicle is in a hybrid drive mode, to meet an engine torque request while ensuring that the engine is operated at an optimal operation point; and determining, based on the initial allocation, whether the motor is capable of fully responding to the arbitrated torque, if so, controlling the motor to respond to the arbitrated torque in priority, otherwise controlling the engine and the motor to cooperatively respond to the arbitrated torque.

An example method for controlling a vehicle includes generating, based on performing an optimization on a blended smooth wheel domain fuel consumption map subject to a modified torque availability constraint, one or more wheel domain control commands, converting the one or more wheel domain control commands to one or more powertrain-executable engine domain control commands, and transmitting the one or more powertrain-executable engine domain control commands to a powertrain of the vehicle, the powertrain configured to operate a plurality of gears, wherein the one or more powertrain-executable engine domain control commands enable the vehicle to track a reference kinematic trajectory associated with a vehicle speed driving plan within a predetermined tolerance.

A hybrid vehicle includes an engine which generates power by combustion of fuel; a drive motor which generates power, and is selectively operated as a generator to generate electrical energy; a battery which is connected to the drive motor and supplies electrical energy to the drive motor and charges the electrical energy generated in the drive motor; a battery management system which measures a State of charge (SOC) value of the battery; and a controller which is configured to determine a final target torque of the engine in a Hybrid Electric Vehicle (HEV) mode based on an SOC section in which the SOC value of the battery measured in the battery management system belongs.

The objective is to improve driving feeling at a time of acceleration operation or deceleration operation, by recognizing driver's intention of acceleration or deceleration during straight-ahead running. A driving-assistance control apparatus according to the present disclosure includes a straight-running determination unit that determines whether or not a vehicle is running straight, a head-position detection unit that detects a head position of a driver, a driving-posture determination unit that determines the posture of the driver, based on the head position detected by the head-position detection unit, and a driving-assistance control unit that performs acceleration preparation control for raising a reaction speed for acceleration operation or deceleration preparation control for raising a reaction speed for deceleration operation in accordance with an output of the driving-posture determination unit, when the straight-running determination unit determines that a vehicle is running straight.

The second rotary electric machine outputs the power to the other of the pair of front wheels and the pair of rear wheels, through a second power transmission path. The control device obtains a target electrical path amount enabling the engine operation point to become a target operation point, and causes a speed change device provided in the second power transmission path to establish a gear ratio enabling the target electrical path amount to be attainable.
