A method is provided for controlling a hybrid drive train comprising a first partial drive train including an internal combustion engine having a crankshaft and a second partial drive train, which is separated from the first partial drive train by a torsional elasticity having an electric machine with a rotor A rotational characteristic value of the first partial drive train is detected via a sensor arranged on the torsional elasticity A rotational characteristic value of the rotor is detected via a device engaged with the rotor. A quality index is determined based on the rotational characteristic value of the first partial drive train and the rotational characteristic value of the rotor. The electric machine is controller to optimize the quality index.

One embodiment relates to a hybrid vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, a rechargeable power source, and a PTO. The hybrid vehicle drive system can include a control system for reducing or eliminating regenerative braking during a traction control or anti-lock braking event.

A vehicle control apparatus for controlling a vehicle through a control program using at least one parameter. The at least one parameter is corrected by respective at least one correction value that is obtained after start of execution of a learning operation. The vehicle control apparatus includes: a learning-data storage portion configured to store, as learning data, the at least one correction value obtained after the start of the execution of the learning operation; and a learning-data rewrite portion configured, when the control program is updated, to execute a rewriting operation for rewriting the at least one correction value as the learning data from a pre-update correction value to a post-update correction value, such that the post-update correction value has the same sign as the pre-update correction value, and an absolute value of the post-update correction value is smaller than an absolute value of the pre-update correction value.

A braking force controller includes: a target jerk calculation unit; a first estimation unit configured to estimate an increment of braking force when a prescribed factor that increases braking force to be generated by the first actuator unit currently occurs; a second estimation unit configured to estimate the increment of the braking force when the prescribed factor occurs within a prescribed period; and a control unit configured to determine a negative jerk generated when the second actuator unit generates the braking force such that a sum of the negative jerk and the jerk generated by the first actuator unit without the prescribed factor becomes the target jerk. When the increment of the braking force due to the prescribed factor is larger than a prescribed value, the control unit corrects the determined negative jerk such that an absolute value of the negative jerk becomes smaller.

A method for determines the drive train sensitivity of a drive train of a motor vehicle. A vehicle body is placed in longitudinal oscillations in the direction of travel and a parameter for the drive train sensitivity is determined as a function of the determined longitudinal accelerations of the vehicle body and the resultant angular accelerations of a transmission input shaft of a transmission of the motor vehicle.

Operating an autonomous machine using analysis of machine vibration while it is operational. Accelerometers are used to measure the machines vibrations while it is being operated. If the vibrations exceed a predetermined acceleration a controller adjust the velocity of the machine to prevent/reduce further vibrations.

Provided are a control device and a control method for a vehicle, and storage medium which are capable of reducing vibration, noise, and speed change shock caused by a downshift when an increase in a required driving force is predicted during automated drive. In a control device (100) for a vehicle which is equipped with an automatic transmission (TM) and capable of automated driving control, when an increase in a required driving force is predicted during the execution of the automated driving control, a vehicle speed of the vehicle is maintained or decelerated until an increase timing of the required driving force, an engine rotation number is increased within a standby period until the increase timing of the required driving force, a torque of the engine is decreased in response to the increase in the engine rotation number, and a shift gear level of the automatic transmission is shifted downward.
