A system is provided for vehicle range prediction. The system determines a change in mass to a vehicle while driving. Additionally, the system calculates a vehicle load in response to determining the change in mass and adjusts a vehicle range in response to calculating the vehicle load. The vehicle range is indicative of a distance in which the vehicle is predicted to travel with a remaining fuel. The adjusted vehicle range is based on the vehicle load.

A vehicle control apparatus includes a motor generator, an engine, a transmission mechanism, a clutch mechanism, and a control system configured to control the motor generator, the engine, the transmission mechanism and the clutch mechanism.

The control system is configured to set a shift period based on a transmission gear ratio of the transmission mechanism. The control system is configured to: control, upon switching from the first traveling mode to the second traveling mode, the clutch mechanism to be in a state where the clutch mechanism is engaged for an entirety of the shift period; and under the state where the clutch mechanism is engaged, decrease a torque of the engine and increase a power running torque of the motor generator.

A sudden acceleration prevention method for a vehicle includes the following steps, which may be performed by a controller: monitoring an output signal of an accelerator pedal sensor so as to obtain a detected operation state of an accelerator pedal, determining whether the detected operation state of the accelerator pedal is within a predetermined brake pedal operation range, determining whether the detected operation state of the accelerator pedal is within a predetermined accelerator pedal and brake pedal overlapping operation range if the detected operation state of the accelerator pedal is within the predetermined brake pedal operation range, and outputting an output reduction control signal of the vehicle if the detected operation state of the accelerator pedal is not within the accelerator pedal and brake pedal overlapping operation range.

Disclosed is a method of controlling regenerative braking of a hybrid vehicle, and a device thereof. The method includes: controlling, by a controller, a hybrid vehicle to start a braking operation in response to a brake pedal operation signal; and after the braking operation of the hybrid vehicle is started, controlling, by the controller, a second motor that is connected to an input shaft of a transmission of the hybrid vehicle to perform regenerative braking.

A device for controlling driving of an electric four-wheel drive vehicle at the time of shift is provided. The device controls driving of an electric four-wheel drive vehicle to minimize energy loss occurring on a power transmission path during shift, thereby improving fuel efficiency.

A method of controlling launch of a vehicle, may include setting step in which a controller sets a basic target engine speed; a transient control step in which the controller controls a clutch torque based on the basic target engine speed; a transient state determining step in which the controller determines, whether a transition period of change of the engine speed elapsed; a first correction amount determination step in which the controller determines a correction amount; a correction applying step in which the controller adds the correction amount to the predetermined target engine speed and then determines a final target engine speed; an error determination step in which the controller determines the engine speed control error; and a feedback determination step in which the controller uses the engine speed control error and determines a feedback control amount for feedback-controlling a clutch actuator.

A method for determining a reference control profile for a vehicle, including determining (A1) a plurality of control profiles for the vehicle (1) based on topographic information for one and the same future route segment and selecting (A2) one of the plurality of control profiles as a reference control profile, the selection (A2) being based on a tradeoff criterion considering resource consumption and drivability of the plurality of control profiles. The disclosure also relates to a control arrangement (2) for determining a reference control profile for a vehicle (1) and a vehicle comprising the control arrangement (2).

A vehicle controller for a vehicle including a drive source including an electric motor includes: a sense-of-beating producer configured to acquire a total required torque which is a required torque of the entire vehicle and configured to derive a total target torque corresponding to the total required torque as applied to a predetermined engine combustion cycle; and a target motor torque deriver configured to, based on the total target torque, derive a target motor torque for torque control of the electric motor. The vehicle controller controls the electric motor based on the target motor torque.

A control system for a powertrain system includes an electronic control unit structured to receive ground speed data and load factor data. The electronic control unit determines an engine speed command to an engine and a torque command to a variable-torque transmission based upon an engine speed limit and a torque scale factor that can vary with ground speed and load factor. The commands produce an economy output of the powertrain to reduce fuel consumption.
