A control method for a hybrid vehicle (1) is provided. The hybrid vehicle includes an electric motor (13) that drives the vehicle to travel, a generator (12) that supplies power to the electric motor, and an engine (11) that drives the generator. The control method includes storing the timing at which an amount or factor of change in target driving force (Fd) for the vehicle becomes a predetermined threshold or more, calculating an estimated trajectory of the rotational speed of the engine in accordance with the amount or factor of change in the target driving force, and when an increase request for power generation is issued to the engine at different timing than the timing, controlling the rotational speed of the engine on the basis of the calculated estimated trajectory.

Systems and control methods can provide for determining a TrnAin torque request from desired vehicle acceleration in a vehicle that utilizes a WTC architecture to allow for smooth transition between different transmission states, such as torque converter bypass clutch states and shifts between transmission gear ratios. The methods provide consistent and smooth vehicle acceleration profile during transmission state transitions. The methods also provide the ability to track the desired vehicle acceleration consistently from virtual driver demand sources, such as adaptive cruise control, autonomous vehicle, or remote parking, without allocating any additional resource to account for transmission state transitions. The proposed methods are applicable to any TC-based automatic transmission drivetrain, such as conventional powertrain, MHT, P4 HEV, or even BEV powertrains where the motor is located on the impeller side of a torque converter.

An automatic speed control device includes: an upper limit speed setting part for setting a first speed as an upper limit speed during running on a main road and setting a second speed slower than the first speed as the upper limit speed during running on a connecting road; a target speed setting part for setting a target speed to less than or equal to the upper limit; and a speed control part for controlling a vehicle speed based on the target speed. The speed control part makes the vehicle accelerate according to a depression amount of the accelerator pedal when the pedal is depressed. The upper limit speed setting part sets the upper limit speed to a speed faster than the second speed and less than the first speed when the vehicle speed has become faster than the second speed due to depression of the pedal.

Provided is a vehicle that can improve vehicle posture control or operation performance during accelerating turn. A vehicle is provided with: a left drive wheel and a right drive wheel connected to a motor; a required drive power amount input device for inputting a required drive power amount; and a required turn amount input device for inputting a required turn amount. The vehicle further includes a turn control device that adjusts a power difference between the left drive wheel and the right drive wheel on the basis of a time derivative value of the required drive power amount in addition to the required turn amount.

A vehicle control device disengages a clutch provided between an engine and a driving wheel at a brake-off and an accelerator-off during traveling of the vehicle, and stops the engine and carries out inertia traveling. The vehicle control device starts the engine by the push-start by engaging the clutch and by transmitting the power of the driving wheel to the engine, if it is determined that a brake pedal has been depressed during the inertia traveling.

A method for improving operating a vehicle that includes an accelerator pedal is disclosed. In one example, the method assesses a vehicle for accelerator pedal degradation and applies control actions to the vehicle is accelerator pedal degradation is determined. The control actions may include adjusting a throttle position and adjusting vehicle brakes.

A method for operating an internal combustion engine of a motor vehicle, whereby an electrically heated component of an exhaust aftertreatment system being supplied with electrical power via an electric machine driven by the internal combustion engine, a load point shift of the internal combustion engine being carried out by an activation or a deactivation of the component or by a temporary storage of the necessary electrical energy for operating the component in a battery.

A driving behavior evaluation device, includes: a memory; and a processor coupled to the memory, the processor being configured to: acquire onboard sensor information that is detected by a sensor installed in a vehicle and that includes a depression amount of an accelerator pedal, acquire map information including information regarding an intersection, and in a case in which an event has been detected, render a lower driving evaluation than in a case in which the event is not detected, the event being an event in which the depression amount of the accelerator pedal increases or decreases at least once within a predetermined time after the vehicle has arrived at a temporary stop position, or has temporarily stopped, at the intersection.

In a method for operating a powertrain of a vehicle, a first electric motor can provide a first drive torque, a second electric motor can provide a second drive torque and an internal combustion engine can provide a third drive torque to an output. The internal combustion engine and the first electric motor can be connected to the output via a separating clutch. In the event of a specific acceleration requirement, the separating clutch is closed regardless of a state of the internal combustion engine, and the first electric motor delivers the first drive torque and the second electric motor delivers the second drive torque together to the output.

The present invention provides a method of controlling a vehicle (1) in which rear road wheels (2b) are driven. The method includes: a step of selecting a first pedal mode in which an acceleration is set based on a depression amount of an accelerator pedal, or a second pedal mode in which the acceleration and a deceleration are set; a step of setting a basic torque based on a driving state of the vehicle; a step of setting an incremental torque to allow the basic torque to be increased in accordance with an increase in steering angle; and a step of generating a torque which is determined by adding the incremental torque to the basic torque, wherein the incremental torque setting step includes setting the incremental torque to different values between when the first pedal mode is selected and when the second pedal mode is selected.
