A control device for a vehicle drive unit is configured to control, based on an operating state of a vehicle, a vehicle drive unit having one or more power sources. The control device includes a processor and a storage device. The storage device is configured to store a vehicle front-rear acceleration prediction model being a machine learning model that receives as an input a command torque and outputs predicted acceleration. The processor is configured to: execute a predicted acceleration calculation process using the vehicle front-rear acceleration prediction model; and execute a command torque calculation process to calculate the command torque that minimizes an evaluation function. The evaluation function minimizes a deviation of the predicted acceleration with respect to a target vehicle front-rear acceleration according to a target torque based on the operating state while reducing a deviation of the command torque with respect to the target torque.

A hybrid vehicle (HEV) provides an improved sensation of acceleration. An example method for controlling an engine of an HEV which includes a first motor directly connected to an engine and a second motor located at an input side of a transmission, may include determining a requested torque, determining a compensation torque for compensating an acceleration loss in a shift process based on the requested torque, a torque of the second motor, a torque of the engine and information on the shift, determining an available torque of the first motor, and determining a final torque of the first motor based on the compensation torque and the available torque.

Systems and methods for coordinating and providing towing acceleration assistance between towing vehicles and towed vehicles during vehicle towing events are disclosed. The towing acceleration assistance may be provided by the towed vehicle in the form of an assistive propulsive torque to assist the towing vehicle with acceleration during the towing event when one or more vehicle conditions indicate a need for the towing acceleration assistance. The towing acceleration assistance may end when the one or more vehicle conditions no longer indicate the need for the towing acceleration assistance.

When an acceleration request is issued, an electronic control unit for a hybrid vehicle performs control for producing an acceleration feeling of setting a target engine rotation speed to an initial rotation speed (=basic initial value+initial value correction value) which is lower than an optimal-fuel-efficiency rotation speed at which required engine power is able to be most efficiently output and increasing the engine rotation speed from the initial rotation speed to the optimal-fuel-efficiency rotation speed at a rotation speed increase rate (=basic increase rate+increase rate correction value) based on the elapse of time. When the target supercharging pressure is high, the initial value correction value is set to a greater value and the increase rate correction value is set to a greater value than when the target supercharging pressure is low.

A control system for controlling electrical power consumption from energy storage means by a traction motor of a vehicle caused by a wheel slip event includes: one or more electronic controllers configured to: receive a torque request for the traction motor; determine a current known prevailing speed value of the traction motor; determine a maximum allowable increase in speed of the traction motor of to occur during a latency period associated with the prevailing speed value of the current known speed of the traction motor; determine an electrical power consumption limit in dependence on the torque request, the current known prevailing speed value of the traction motor of the vehicle and the maximum allowable increase in speed of the traction motor; and control torque provision of the traction motor in dependence on the torque request and the electrical power consumption limit.

When it is determined that predicted required drive power (Tf) which is drive power predicted to be required for a vehicle is greater than a first threshold value (TH1) set within a range of drive power that can be outputted in a second mode, or when actual required drive power (Ta) is greater than the first threshold value (TH1), a control device (10) sets an operating mode to a first mode in which a first engagement device (CL1) is brought into an engaged state and a second engagement device (CL2) is brought into a disengaged state, to control a rotating electrical machine (MG1) and an internal combustion engine (EG) to output the actual required drive power (Ta). In other cases, the control device (10) sets the operating mode to the second mode in which the first engagement device (CLl) is brought into a disengaged state and the second engagement device (CL2) is brought into an engaged state, to control the rotating electrical machine (MGl) to output the actual required drive power (Ta).

A control system for a hybrid vehicle configured to reduce electricity consumption by a motor in a condition where a maximum output torque of an engine is restricted. A controller is configured to: calculate a current maximum torque of the engine when increasing a speed of the engine to achieve an acceleration demand; determine whether the current maximum torque of the engine is less than an inertia torque required to increase the speed of the engine; and adjust the reaction torque of the first motor to a value less than a predetermined value, if the current maximum torque of the engine is less than the inertia torque required to increase the speed of the engine.
