An MG1 torque at a time of decreasing an engine speed of an engine is made larger when a turbocharging pressure by a turbocharger is higher than when the turbocharging pressure is lower. In this way, even if the losses of pumps of the engine differ due to the remaining turbocharging pressure during a transition of stopping the engine in turbocharging, it is possible to appropriately reduce the engine speed. Therefore, when the engine is being brought to a stop, it is possible to appropriately suppress vibration generated in the vehicle.

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 controller and a method for controlling motion of a vehicle is provided. The method comprises acquiring motion information including a current state of the vehicle and a desired state of the vehicle, determining a combination of a steering angle of the wheels and motor forces for moving the vehicle from the current state into the desired state by using a first model of the motion of the vehicle and a second model of the motion of the chassis of the vehicle, determining a cost function of the motion of the vehicle, optimizing the cost function of the motion of the vehicle to compute a command signal for controlling the steering wheel and the plurality of electric motors, and controlling the steering angle of the wheels and the motor forces based on the command signal.

A number of illustrative variations may include a system and method of controlling vehicle slowing while implementing brake-to-steer functionality that may include providing a feed-forward gain on vehicle propulsion torque to achieve or maintain target longitudinal acceleration and replicate the behavior of a vehicle not using brake-to-steer. The system may manipulate propulsion of the vehicle to manage longitudinal acceleration disturbance and speed disturbance during brake-to-steer.

A number of illustrative variations may include a system including brake-to-steer algorithms may achieve lateral control of a vehicle without longitudinal compensation but may also force a vehicle to slow down too rapidly before appropriate lateral movement can be achieved and may deliver an unnatural driving experience for vehicle occupants. A more natural feeling deceleration may be achieved by optimally selecting appropriate transmission shifts to allow for optimal engine speed or electric motor speed and torque based on current vehicle speed thereby reducing undesirably longitudinal disturbance.

An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.

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.

A system for adjusting performance of an electric motor in a hybrid vehicle during a combustion event. The system includes a combustion engine including a cylinder, an electric motor including an electric motor shaft and connected to the combustion engine via a drive shaft, and an inverter controller connected to the electric motor. The inverter controller includes an electronic processor configured to receive a rotational position of the electric motor shaft, determine, based on the rotational position of the electric motor shaft, whether a combustion event is occurring in the cylinder, and when a combustion event is occurring in the cylinder, preform one selected from the group comprising increase torque produced by the electric motor and decrease the torque produced by the electric motor.

Methods and systems for operating an electric vehicle in neutral are provided herein. The vehicle system, in one example, includes an electric machine rotationally coupled to a driveline and an input device with a neutral position. The system further includes a control unit with instructions that when executed, in response to movement of the input device into the neutral position, cause the control unit to operate the electric machine to apply a regenerative torque to a driveline and generate electrical energy.

A hybrid drive system has an internal combustion engine having a crankshaft, an electric motor having a rotor and a stator, a dual clutch transmission having an input shaft, a dual claw clutch having a first claw clutch and a second claw clutch, a first sub-transmission, and a second sub-transmission. The first claw clutch is non-rotatably connects a first sub-transmission input shaft of the first sub-transmission to the input shaft. The second claw clutch non-rotatably connects a second sub-transmission input shaft of the second sub-transmission to the input shaft. The rotor is arranged in such a way that torques starting from the rotor on an output side of the second claw clutch can be introduced into the dual clutch transmission via the second sub-transmission input shaft.
