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.

The invention relates to a method for determining a characteristic curve of a hybrid separating clutch of a hybrid vehicle without a test stand, wherein the hybrid separating clutch separates or connects an internal combustion engine and an electric motor and the hybrid separating clutch is slowly actuated on the basis of a position which the hybrid separating clutch assumes in an unactuated state, and a clutch characteristic curve is determined as a function of a clutch torque over a path of the hybrid separating clutch. In a method by which a characteristic curve of the hybrid separating clutch can be reliably defined without a test stand, a clutch torque which underlies the characteristic curve of the hybrid separating clutch is determined from the torque of the internal combustion engine in the case of a running internal combustion engine and a motion state of the electric motor which brakes the internal combustion engine while the hybrid separating clutch is moving.

In some examples, a controller receives information of a route of a vehicle, and selects a first parameter set from among a plurality of parameter sets based on the route 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 first parameter set to control a setting of the one or more adjustable elements of the vehicle.

A controller of a vehicle, while the vehicle is within a predefined geofenced region and responsive to the vehicle entering park, increases a maximum state of charge threshold for the battery and decreases a minimum state of charge threshold for the battery. The controller also, while the vehicle is located within the predefined geofenced region and responsive to the vehicle exiting park, decreases the maximum state of charge threshold and increases the minimum state of charge threshold.

The hybrid vehicle includes an engine, a motor connected to the engine, and an electronic control unit configured to control the motor to execute motoring to rotate a crankshaft of the engine. The electronic control unit is configured to execute speed-drop offset control when a rotation speed of the engine falls below a first rotation speed that is lower than a self-sustaining rotation speed of the engine while the engine is operated in a self-sustaining manner at the self-sustaining rotation speed.

Aspects of the present invention relate to a method and to a control system for controlling an engine and an electric traction motor of a vehicle, the control system comprising one or more controllers, wherein the control system is configured to: receive an indication of engine speed during engine idling; and control the electric traction motor to reduce a difference between the engine speed and an engine idle speed target

In some examples, a controller receives information of a route of a vehicle, and selects a first parameter set from among a plurality of parameter sets based on the route 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 first parameter set to control a setting of the one or more adjustable elements of the vehicle.

Aspects of the present invention relate to a method and to a control system for a vehicle, the method comprising: determining that a trigger condition is satisfied, wherein satisfaction of the trigger condition is dependent on a vehicle speed of the vehicle relative to at least one threshold speed, the at least one threshold speed having a value corresponding to is vehicle speed no greater than four metres per second; and based at least on the determination, controlling when a mode change between a first operating mode and a second operating mode is performed, wherein in the first operating mode the internal combustion engine is in a disconnected state not configured to provide tractive torque, and an electric machine is configured to provide tractive torque, and wherein in the second operating mode at least the internal combustion engine is in a connected state configured to provide tractive torque.

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.

A method of controlling the operating mode of a motor vehicle includes transitioning between driving and coasting modes and vice-versa automatically in response to a driver trigger. The method controls an engine of the motor vehicle to bring a driveline driven by the engine via an electronically controlled clutch into a lash state before engaging or disengaging the electronically controlled clutch thereby preventing driveline disturbances from being produced by the transition.
