Methods and systems are provided for controlling a vehicle including a manual transmission to prevent cold-start drive-away. In one example, a method for a vehicle with a driver clutch pedal may include preventing one of a clutch coupled between an input of a transmission and an engine output from closing and a driver-operated gearshift lever for adjusting a gear of the transmission from coming out of neutral in response to a catalyst light-off condition.

A drive control device of a hybrid vehicle provided with a motor and an engine is provided. The control device includes a processor configured to execute a target fuel consumption setting module that sets a target fuel consumption according to the number of lapsed days from a given reference timing, an actual fuel consumption calculating module that calculates an actual fuel consumption actually consumed during a specific period from the reference timing, a forcible consumption calculating module that compares the actual fuel consumption with the target fuel consumption, and when the actual fuel consumption is less than the target fuel consumption, calculates a forcible consumption of fuel according to a difference therebetween, and a traveling controlling module that controls the drive of the motor and the engine so that traveling at least with the engine is continuously performed until the fuel is consumed by the forcible consumption.

A hybrid vehicle includes an engine, an electric machine, a disconnect clutch configured to selectively couple the engine to the electric machine, and a controller. The controller is programmed to, in response to a request to start the engine with the electric machine, command a target pressure to the disconnect clutch that depends on a seal friction derived from a measured line pressure of the disconnect clutch and a rate change of the measured line pressure.

Various disclosed embodiments include illustrative systems, vehicles, and methods. In an illustrative embodiment, a system includes a sensor configured to generate route information, and a control unit. The control unit includes a processor in signal communication with the sensor and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the processor to receive the generated route information, generate a wheel signal responsive to the received route information indicating a change in wheel engagement status, and output the wheel signal to a disconnect.

Systems and methods of autonomously controlling a vehicle across the grip driving and drift driving operating ranges, are provided. The contemplated autonomous control can be effectuated using a closed-loop control system. In some embodiments, closed-loop control may be accomplished by deriving control laws involving sideslip angle, yaw rate, wheel speed, and other vehicle states. These control laws may be used to control the vehicle in a stable drift condition.

A hybrid drive device has an internal combustion engine, a clutch transmission which has at least one free partial transmission and a partial transmission connected to an electric machine with in each case a clutch, and at least one electric machine. In order to start the internal combustion engine, pulse energy is provided from an inertia of the clutch associated with the free partial transmission and/or a rotation in the free partial transmission.
