A control apparatus for controlling a vehicle includes a driving motor configured to drive the vehicle by outputting motor torque based on a supply voltage from a battery, and an engine configured to drive the vehicle by outputting engine torque. The control apparatus may acquire driving mode data which is calculated based on traffic information from the current position to the destination of the vehicle and dimension information of the vehicle, and control the vehicle to drive to the destination according to a driving mode which is determined by applying a travelling condition of the vehicle to the acquired driving mode data, where the power distribution ratio of the motor torque to the engine torque is reflected in the driving mode data.

An engine has a variable valve actuation device for controlling an actuation characteristic of an intake valve that is an amount of lifting the intake valve and/or a working angle on the intake valve. When the intake valve, having the actuation characteristic (or lifted in an amount and/or worked by a working angle), as controlled by the variable valve actuation device, has the actuation characteristic fixed (YES in S120), a range applied to set therewithin an output that the engine is required to provide is limited to be narrower and a power storage device's controlled target SOC is raised to be higher (S150, S160, S170) than when said actuation characteristic is not fixed (NO in S120).

A hybrid electrical vehicle and a method for controlling a hybrid electrical vehicle are provided. The vehicle includes: a transmission device (1) connected with wheels (2a and 2b) of the hybrid electrical vehicle; an engine (3) and a gearbox (4), wherein the engine (3) is connected with the transmission device (1) via the gearbox (4); an electric motor (5) and a gear reducer (6), wherein the electric motor (5) is connected with the transmission device (1) via the gear reducer (6); a power battery (7) configured to supply power to the electric motor (5); and a control module configured to start the engine (3) and the electric motor (5) according to a working mode selected by a user from a plurality of working modes, and to control the vehicle to switch between the plurality of working modes according to a driving state of the vehicle and/or a working state of the power battery.

A first heater heats a vehicle compartment by using cooling water of the internal combustion engine. A second heater heats the vehicle compartment by using electrical power supplied by the electrical storage device. The controller during driving of the internal combustion engine, when a temperature of the cooling water is equal to or higher than a reference temperature, controls the internal combustion engine to stop; when the second heater is operated during driving of the internal combustion engine, when a state quantity indicating a state of charge of the electrical storage device is equal to or higher than a threshold, controls the second heater such that an amount of heat generation of the second heater is higher than that generated when the state quantity is less than the threshold; and sets the reference temperature to be low as compared to when the state quantity is less than the threshold.

Even if an adjustable speed limitation function (ASL) sets a vehicle speed upper limit to a relatively low vehicle speed, a control unit 10 is configured to, in order to suppress the problem of a decrease in fuel efficiency while the ASL is executing the vehicle speed limitation, suppress an output of an engine 2 so that the vehicle speed does not exceed the vehicle speed upper limit, and cause a gear stage of an automatic transmission 3 to be shifted up to a higher speed side gear stage having higher fuel efficiency than a gear stage that is set based on the driving state of a vehicle 1, when a deviation between the vehicle speed detected by a vehicle speed sensor 21 and the vehicle speed upper limit that is set by a vehicle speed upper limit setting switch 24 becomes less than a predetermined threshold.

The invention relates to a control system for a hybrid electric vehicle (100), the vehicle having a powertrain (135) comprising at least one electric propulsion motor (123) and at least one engine (121), the control system being operable to control the vehicle to operate in an electric vehicle (EV) mode in which the at least one engine remains switched off and the at least one electric propulsion motor is configured to deliver drive torque and a boost mode in which the at least one engine is switched on to provide additional power to drive the vehicle. When the vehicle is operating in EV mode the system is further operable to determine whether a boost location exists ahead of the vehicle being a location at which a gradient of a driving surface is sufficiently high to require selection of the boost mode, the control system being operable automatically to command starting of the at least one engine before the boost location is reached.

A control system is for a vehicle that includes an internal combustion engine. The control system includes an electronic control unit. The electronic control unit is configured to limit an output of the internal combustion engine when the electronic control unit determines that the vehicle runs in an unmanned state, such that the output of the internal combustion engine is lower the vehicle runs in the unmanned state than when the vehicle runs in a manned state.

Disclosed is a bidirectional transmission control system for a vehicle. A road surface recognition apparatus collects an image of a road surface on which a vehicle drives currently, and forwards, after recognizing the type of the road surface on which the vehicle drives currently according to the image of the road surface, a corresponding first terrain mode request signal to an all-terrain controller through a signal transfer apparatus, so as to start a corresponding terrain mode in an all-terrain adaptive mode. In addition, the all-terrain controller forwards execution information about the terrain mode to the road surface recognition apparatus through the signal transfer apparatus, so as to implement state feedback of the terrain mode currently executed. The inconsistency of information transmission rates between an all-terrain control system of a vehicle and an input system can be coordinated, thereby aiding in real-time switching of various terrain modes.

A controller for a vehicle, the vehicle including an engine and a transmission gear device, the controller includes an electronic control unit. The electronic control unit is configured to: (i) stop the engine automatically when predetermined engine stopping conditions are fulfilled, the predetermined engine stopping conditions including fulfillment of a shift position condition of the transmission gear device, (ii) start the engine automatically when a predetermined waiting time has elapsed since a change in shift position, and (iii) change the waiting time depending on the duration of an automatic stop of the engine.

Methods and systems are provided for integrating a bi-fuel engine with a CVT transmission. Responsive to a driver demand, a controller may determine whether to maintain usage of a current fuel or transition to an alternate fuel based on the cost efficiency of the transition and further based on any engine limitations that may be incurred at the engine speed-load following the transition. To improve the net fuel economy benefit while addressing the engine limitation, a fuel transition may be combined with a CVT adjusted engine speed-load regime, while maintaining engine power output.
