A method is for operating a vehicle which has actuators for influencing a driving behavior of the vehicle. The method includes sensing a setpoint for the driving behavior, in particular a steering angle set by a driver, and depending on the setpoint for the driving behavior, a first pilot control variable is determined using a model for the vehicle. Depending on the first pilot control variable, a second pilot control variable is determined using at least two partial models for the driving behavior of the vehicle, which differ due to the use of at least one of the actuators. Depending on the first pilot control variable and depending on the second pilot variable, a first setpoint for a first actuator is determined. The first setpoint is output in order to actuate the first actuator.

A control apparatus of a vehicle that calculates a feedback requested acceleration for maintaining an inter-vehicle distance to a target distance and a feedforward requested acceleration for causing the own vehicle to travel following a communicating preceding vehicle and calculates a requested acceleration of the own vehicle on the basis of the feedback and feedforward requested accelerations. The apparatus executes a control that causes the own vehicle to travel following the preceding vehicle by controlling the acceleration of the own vehicle such that the acceleration of the own vehicle corresponds to the requested acceleration of the own vehicle. The apparatus sets the feedforward requested acceleration to zero when a shift lever of the preceding vehicle is positioned at a shift position other than a shift position that causes the preceding vehicle to travel forward and the feedforward requested acceleration is larger than zero.

A vehicle driving assistance device has an estimation unit for separately estimating the temperatures of the braking portions in the left and right drive wheels, a first execution unit for executing vehicle stabilization control for separately controlling the braking forces exerted on the vehicle wheels, and a second execution unit for executing turning assist control for exerting braking force on the inside drive wheel of the left and right drive wheels when the vehicle is turning while vehicle stabilization control is not being executed. During turning assist control, the braking force exerted on the inside drive wheel when the difference in pad temperatures between the left and right drive wheels is equal to or greater than a reduction determination value is reduced to a greater extent than the braking force exerted on the inside drive wheel when the pad temperature difference is less than the reduction determination value.

A hybrid electric power-split vehicle, equipped with a continuously variable transmission coupling an electric motor/generator (EM) with a combustion engine (CE), includes systems and methods that reduce possible resonant noise and vibration during CE startup, by improved EM control, to generate compensating EM torque to counter act such possible resonant noise and vibration. The systems and methods include predetermined baseline CE operating condition (OC) cranking torque profiles stored as OC grids (SOCGs). A start profile is generated from selected cranking torque SOCGs, and also from selected historical start OCGs (HOCGs) of prior engine and/or CE starts, which include prior start noise and vibration metrics along with prior start OCs and related parameters. The start profile is calibrated using a blend factor that is generated from comparisons of SOCGs, and utilized to generate a feed-forward torque signal that adjusts EM torque to reduce the startup noise and vibration resonances.
