    • A variable valve timing controller adjusts valve timing of an intake valve and/or an exhaust valve by varying a motor speed relative to a camshaft. When an engine is running under a predetermined condition, an actual valve timing is calculated based on a cam angle signal and crank angle signal every when the cam angle signal is inputted. A final valve timing is calculated by adding a valve timing variation amount to the actual valve timing at the time the cam angle signal is outputted. The valve timing amount is periodically calculated based on a difference between a motor speed and a rotational speed of the intake camshaft. When the engine is running under another condition, only actual valve timing at the time the cam angle signal is outputted is calculated.
    • 可变气门正时控制器通过改变相对于凸轮轴的电动机转速来调节进气门和/或排气门的气门正时。 当发动机在预定条件下运行时,每当输入凸轮角信号时,基于凸轮角信号和曲柄角信号计算实际气门正时。 通过在输出凸轮角信号时将气门正时变化量与实际气门正时相加来计算最终气门正时。 基于电动机速度和进气凸轮轴的转速之间的差异周期性地计算气门正时量。 当发动机在另一条件下运行时,仅计算在输出凸轮角信号时的实际气门正时。

    • A vehicle includes: an electric motor that outputs power to a drive shaft that is coupled to a first wheel, which is a primary drive wheel; an electrical storage device that exchanges electrical power with the electric motor; a braking system that can independently apply a braking force to the first wheel and a second wheel that is a free rolling wheel or a drive wheel other than the first wheel, regardless of a braking request by a driver; and a control unit that controls the braking system and the electric motor such that the braking system applies the braking force only to the second wheel and that output torque of the electric motor becomes equal to or lower than specified torque until rotational speed of the electric motor reach specified revolution when a start-up request is made by the driver while the vehicle is at a halt on a driving road surface whose inclination, which is acquired by an inclination acquisition device, is larger than or equal to specified inclination. The present invention also relates to a control method of the vehicle.

    • At an intake timing of an initial combustion cylinder, an actual intake valve timing is adjusted to a target intake valve timing corresponding to a target intake air flow rate of the initial combustion cylinder. At intake timing of the other cylinders which contributes to increment of the engine speed after the initial combustion, the actual intake valve timing is adjusted to a target valve timing corresponding to a target intake air flow rate of the other cylinders. Thereby, the intake air flow rate of each cylinder is accurately controlled, so that the increment of the engine speed is restricted within a range in which a startability is not deteriorated and a vehicle vibration and an over shoot of the engine speed is appropriately restricted.
    • 在初始燃烧气缸的进气正时,将实际进气门正时调整为与初始燃烧气缸的目标进气流量对应的目标进气门正时。 在有助于初始燃烧后的发动机转速增加的其他气缸的进气时刻,将实际进气门正时调整为与其他气缸的目标进气流量对应的目标气门正时。 因此,精确地控制各气缸的进气流量,从而将发动机转速的增加限制在不劣化起动性的范围内,适当地限制发动机转速的车辆振动和过冲。
