Abstract: Disclosed is a vehicle control device which is applied to a vehicle equipped with an engine (10) and an engine torque adjustment mechanism for adjusting an output torque (engine torque) of the engine (10). The vehicle control device comprises a PCM (50) configured, upon satisfaction of a condition that the vehicle is traveling and a steering angle-related value relevant to a steering angle of a steering device is increasing, to control the engine torque adjustment mechanism to reduce the engine torque so as to generate vehicle deceleration to control vehicle attitude. The PCM (50) is further configured to gradually ease the condition, as the number of times of combustion per unit time in the engine (10) becomes smaller.

Abstract: Described is a system and method that provides the ability for an autonomous driving vehicle (ADV) to determine (or estimate) one or more control characteristics for the ADV. In order to determine these control characteristics, the system may perform one or more driving maneuvers such as an acceleration or deceleration maneuver, and a constant velocity maneuver. By performing these maneuvers using various known forces, the system may then perform various calculations to obtain one or more unknown characteristics. For example, the system may determine as estimated mass of the ADV, and as a result, adjust (or tune) various controls of the ADV based on the estimated mass.

Abstract: A desired change of a time derivative of dynamic torque (Tqfw), provided to an output shaft from an engine in a vehicle, from a current value to a new desired value is determined. A current rotational speed difference (Δωpres) is determined between a first end of the powertrain in a vehicle, which rotates with a first rotational speed (ω1), and a second end of the powertrain, which rotates with a second rotational speed. The first rotational speed (ω1) is then controlled on the basis of the desired value of the time derivative for the dynamic torque (Tqfw), a spring constant (k) related to a torsional compliance in the powertrain, and the determined current rotational speed difference {Δωpres). Through control of the first rotational speed, the current value for the time derivative for the dynamic torque is also indirectly controlled towards the desired value.
