Abstract: A vehicle control system includes: a vehicle state detecting device configured to obtain vehicle state information that includes a steering angle of a front wheel; a pitch moment computation unit configured to compute an applied pitch moment to be applied to a vehicle based on the vehicle state information; a deceleration force computation unit configured to compute an applied deceleration force to be generated in the vehicle based on the applied pitch moment; and a deceleration force distribution unit configured to compute a brake device deceleration force to be generated by a brake device and a power plant deceleration force to be generated by a power plant based on the applied deceleration force and state information of the brake device and the power plant.

Abstract: A rotation-speed-calculation-apparatus includes: a detector configured to detect a rotation-angle of an engine; and a CPU and a memory coupled to the CPU. The CPU is configured to perform: calculating an engine-speed each time the detector detects a predetermined-angle based on a time-period required for the engine to rotate the predetermined-angle; and determining whether the engine-speed calculated is in a low-rotation range equal to or lower than a threshold-value or in a high-rotation range over the threshold-value. The CPU is configured to perform: the calculating including: calculating the engine-speed based on a time-period required for the engine to rotate a first-predetermined-angle when it is determined that the engine-speed is in the low-rotation range; and calculating the engine-speed based on a time-period required for the engine to rotate a second-predetermined-angle smaller than the first-predetermined-angle when it is determined that the engine-speed is in the high-rotation range.

Abstract: Provided is a vehicle in which an internal combustion engine can be suitably assisted by a rotating electrical machine. The vehicle is provided with an internal combustion engine, a rotating electrical machine, a transmission, a clutch placed between the transmission and the combination of the internal combustion engine and rotating electrical machine, and a motive power control device that controls the motive power of the internal combustion engine and the rotating electrical machine. The motive power control device calculates additional motive power for the rotating electrical machine on the basis of the difference between the motive-power-transmitting capacity of the clutch and the motive power of the internal combustion engine.

Abstract: A power control device of a vehicle disallows generation of additional power of rotating electrical machines when power of an internal combustion engine is transmitted to a transmission via a clutch and an amount of operation of an accelerator pedal is lower than an operation threshold value. The power control device allows generation of additional power of the rotating electrical machines when power of the internal combustion engine is transmitted to the transmission via the clutch and the amount of operation of an accelerator pedal is higher than the operation threshold value.

Abstract: In a vehicle, a first rotating electrical machine, is connected to first wheels via a clutch, and second rotating electrical machines are connected to second wheels or the first wheels without going through the clutch. A power control device allocates electric power to the second rotating electrical machines with higher priority over the first rotating electrical machine when adding additional power to power of an internal combustion engine, thereby generating power of the second rotating electrical machines with higher priority over power of the first rotating electrical machine.
