Provided is a control apparatus of a vehicle, which includes a transmission mode switching control program for controlling the automatic transmission to switch between an automatic transmission mode and a manual transmission mode, a coast idle stop control program for performing a coast idle stop control in which the engine is stopped automatically and the automatic transmission is changed into a neutral position while the vehicle is traveling, and a coast idle control program for performing a coast idle control in which the engine is made running idle and the automatic transmission is changed into the neutral position while the vehicle is traveling.

Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission are described. In one example, values of an engine spark to engine torque relationship are adjusted to improve engine torque control. The engine is subsequently operated responsive to adjusted values of the engine spark to engine torque relationship.

Disclosed are a hybrid electric vehicle capable of controlling starting of an engine in order to more efficiently realize heating and an engine control method therefor. The method of controlling an engine of a hybrid electric vehicle of the disclosure includes determining whether the engine is in a warmed-up state when a fully automatic temperature control system makes a heating request, making an engine startup request for heating to an engine management system configured to control the engine when the engine is in the warmed-up state, and selectively requesting the engine management system to perform cylinder deactivation (CDA) control on at least some of a plurality of cylinders of the engine depending on whether the engine is in an idling state.

A vehicle includes an engine, motor, powertrain, and controller. The engine and the motor are each configured generate power within the powertrain. The controller is programmed to, in response to full depression of accelerator and brake pedals while the vehicle is stopped and the powertrain is in drive, increase engine power to a maximum power output capacity and increase a motor torque to a predetermined torque output that is less than a maximum torque capacity.

A vehicle control apparatus which includes an engine, an automatic transmission, and drive wheels transmitted with the power of the engine through the automatic transmission, the automatic transmission including a torque converter connected with the engine, a transmission mechanism connected with the torque converter, the torque converter having a pump impeller connected with the engine, and a turbine runner connected with the transmission mechanism, the vehicle control apparatus for a vehicle further including: an input shaft rotational speed sensor that detects the rotational speed Nt of the turbine runner, and a control unit to control the engine to have the rotational speed Ne of the engine raised when a determination condition in which the rotational speed Nt of the turbine runner is not raised even within a standard time T1 lapsed after the engine is started is established.

Systems and methods for reducing perception of transitions from shifting a transmission from neutral to drive are described. In one example, the transmission is shifted from neutral to drive in response to brake pedal motion before the brake pedal is fully released so that timing of pressurizing clutches and engaging a forward gear is advanced to occur while the brake pedal is still applied.

Methods and systems are provided for diagnosing a laser ignition system of an engine. In one example, a controller may operate the laser in a sealed cylinder hours after key-off. Then, the cylinder may be unsealed and a change in exhaust temperature may be correlated with laser functionality.

A drive device for a motor vehicle, having an internal combustion engine that outputs to a gearbox or transmission. A plurality of gear ratios steps provides shiftable driving gears from a starting gear to a highest driving gear. The gearbox has at least one gear ratio step that provides an overrun gear, which cannot be engaged in the traction mode, but only in an overrun mode, in which the vehicle drags the internal combustion engine.

In some examples, a controller receives measurement data from a sensor on a vehicle, determines, based on the measurement data, a condition of usage of the vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined condition of usage of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the selected parameter set on the vehicle.

In some examples, a controller determines a target condition of usage of a vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined target condition of usage of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller transmits, to the vehicle, the selected parameter set to control a setting of the one or more adjustable elements of the vehicle.
