Determining constraints of a velocity of the train with respect to a train position forming a feasible region (FR) for a state of the train during the movement, such that a lower curve bounding the FR has a zero velocity only at the first position, and an upper curve bounding the FR has a zero velocity only at the second position. Determining a control invariant subset (CIS) of the FR, wherein for each state within the CIS there is at least one control action having a value selected from a finite set of values that maintains the state of the train within the CIS. Controlling train movement subject to constraints by selecting a control action maintaining the state of the train within the CIS of the FR.

Systems and methods for operating a driveline of a hybrid vehicle are presented. In one example, a boost phase of a procedure to close a driveline disconnect clutch may be cut short in response to an engine changing state from not rotating to rotating so that the engine may be restarted in an alternative way. The system and methods may also predict a degraded engine start from a low engine cranking speed or a long cranking time duration so that the engine may be started in an alternative way to increase a possibility of starting the engine and decrease the severity of degraded driveline disturbance.

A control apparatus for a vehicle, which is provided with an engine and drive wheels, is configured, during an inertia running or stop of the vehicle, to execute a control for stopping the engine and/or disconnecting the engine from the drive wheels in each area, depending on whether a condition is satisfied or not. The condition is set based on an information transferred from other vehicle in which the control is executable during an inertia running or stop of the other vehicle. The information includes (a) a location information indicative of the each area and (b) an acceleration representative value representing a required acceleration of the other vehicle required by an operator of the other vehicle in the each area. The acceleration representative value is associated with the location information indicative of the each area.

A shifting control method for a vehicle with a dual clutch transmission is provided to achieve quick shifting and direct engaging through quick synchronous control of the rotational speed of an engine and cooperative control of engine torque when a driver intends to rapidly accelerate the vehicle while shifting. The method includes: a rapid acceleration determining step in which a controller determines whether the vehicle is rapidly accelerated based on an output value according to a driving state of the vehicle until a torque handover period is entered, when shifting is started; and an interlocking step of controlling the engagement clutch torque over a predetermined desired engagement clutch torque to cause interlocking based on a torque value determined in accordance with a rapid acceleration level determined in the torque handover period, when the controller determines that the vehicle is rapidly accelerated.

A vehicle includes an engine and at least one controller. In response to a change in a rate of change of a driver control input to the vehicle, the at least one controller is programmed to alter conditions under which the engine will be started and stopped such that engine-on time increases due to the rate increasing and decreases due to the rate decreasing.

A method for operating an internal combustion engine comprises providing a vehicle having an internal combustion gasoline engine including multiple cylinders and wherein the engine is operating in a deactivated cylinder mode, receiving a torque request if a cylinder reactivation torque smoothing mode is active, setting a variable torque ratio to 1.0 if the torque request is greater than a fast exit threshold torque, setting the variable torque ratio to 0.0 if the torque request is less than a slow exit threshold torque, setting the variable torque ratio to a value between 0.0 and 1.0 if the torque request is between the fast exit threshold torque and slow exit threshold torque, and calculating a component of final engine output torque.

A method of cruise control for a vehicle includes the following steps: checking for cruise conditions, determining whether the vehicle is in cruise control mode, and if in cruise control mode, maintaining and controlling the cruising speed of the vehicle until an exit signal is detected; checking the throttle deviation, whereby if not in cruise control mode, the throttle deviation is checked to determine throttle stability; checking cruising speed, whereby if conditions for throttle stability are met, the speed deviation of the vehicle is calculated, and the cruising speed is set; checking the cruising alert for drivers as well as drivers' actions, whereby if conditions for cruising have been met, issuing a cruise control prompt to the driver, and if it is detected that the driver has released the throttle pedal, entering the vehicle into cruise control mode; whereas if the driver fails to release the throttle within a certain period of time after cruise conditions have been met, the next check for cruise conditions is carried out. A system is provided to perform the method. A cruise control which is low-cost, requires no control buttons, and offers a simple product structure is achieved.

An electronic control unit includes processing circuitry. A hybrid electric vehicle has an electric traveling mode, in which the hybrid electric vehicle travels with a system clutch disengaged and an engine in a stopped state, and a hybrid traveling mode, in which the hybrid electric vehicle travels with the system clutch engaged and engine operating. The processing circuitry is configured to control, when the traveling mode is switched from the electric traveling mode to the hybrid traveling mode, a throttle opening degree of the engine at the time of completion of engagement of the system clutch in accordance with the atmospheric pressure such that a constant intake air amount is obtained regardless of the level of the atmospheric pressure.

A driving force control device for a vehicle is provided, which includes a motor, an engine, and a controller. The controller sets a target torque of the vehicle corresponding to accelerator operation, and distributes a target engine torque according to a distribution rule defined beforehand, based on the target torque of the vehicle, and outputs a control signal corresponding to the target engine torque to the engine. The controller estimates a future amount of intake air to a cylinder based on the target engine torque, and estimates a torque of the engine in the future based on the estimated future amount of intake air. The controller sets a target motor torque based on the estimated torque of the engine so that the target torque of the vehicle is achieved in the future, and outputs a control signal corresponding to the target motor torque to the motor.
