The invention relates to an autonomous driving control method, an autonomous driving control system, and a vehicle. The autonomous driving control method includes: estimating motion control capacities of a vehicle on the basis of performance parameters and/or structure parameters of the vehicle; grading autonomous driving functions of the vehicle on the basis of the motion control capacities; and providing the graded autonomous driving functions on the basis of a state of the vehicle. The autonomous driving control method of the invention can provide different grades of autonomous driving functions in different vehicle states, thereby improving driving experience.

An automobile comprising a cooling duct that extends to underneath the automobile to channel cooling air to a component of the automobile when the automobile is in motion is provided. A restriction located within the cooling duct that is moveable from a first position, in which airflow to the component is substantially unimpeded, to a second position in which the airflow to the component is substantially impeded, when the automobile is in motion is further provided. The automobile generates more downforce when the restriction is in the second position versus the first position. A control unit configured to select the position of the restriction to control the downforce generated by the automobile if the temperature of the component is below a predetermined level, and to select the first position for the restriction if the temperature of the component is above the predetermined level, is also provided.

An automobile comprising first and second flaps provided on either side of a centerline on the underside of the automobile is provided. Each flap is deployable from first positions that extend minimally into the flow to respective second positions where each flap extends maximally into the flow of air when the automobile is in motion to reduce the downforce generated by the automobile. A control unit adapted to receive inputs that indicate the dynamic state of the automobile is further provided. The control unit select positions of the first and second flaps depending on the dynamic state to control the downforce generated by the automobile. If the inputs indicate that the automobile is cornering, the positions of the first and second flaps are selected so as to counter roll of the automobile.

A vehicle comprising a flap that is attached to the vehicle in such a way as to permit movement of the flap from a first position to a second position, wherein the flap is configured to alter the downforce generated by the vehicle when the vehicle is in motion by affecting the airflow underneath the vehicle, the effect of the flap on the airflow being dependent upon the second position of the flap.

When a first traveling mode in which a driving wheel is driven by power generated by an electric motor is changed to a second traveling mode in which the driving wheel is driven by at least power generated by an engine, processing circuitry of a control device of a hybrid vehicle according to one aspect executes rotational frequency synchronization control of controlling the engine such that a rotational frequency of a transmission shaft which corresponds to rotation of the engine synchronizes with a rotational frequency of the transmission shaft which corresponds to rotation of the electric motor. During execution of the rotational frequency synchronization control, the processing circuitry controls a clutch such that a degree of engagement of the clutch which corresponds to a degree of power transmission between the engine and the transmission shaft increases.
