Abstract: A control method and a control device are provided for autonomously controlling a host vehicle when turning across an oncoming lane at an intersection with a signal light being green. A determination is made as to whether or not the host vehicle can make a right or left turn while a signal light is still green at a time of the right or left turn, either while the host vehicle in the left lane is waiting in a row of vehicles to make the right turn or while the host vehicle traveling in the right lane is waiting in a row of vehicles to make the left turn at an intersection during travel under autonomous driving. The host vehicle then creeps forward to a start position for starting at a next time the signal light is green upon determining the right or left turn cannot be made.

Abstract: An acceleration rate is controlled so that a vehicle speed during autonomous driving is caused to approach a target vehicle speed. When a host vehicle has caught up with another vehicle traveling ahead of the host vehicle, the vehicle speed of the host vehicle is limited in accordance with a headway distance to the other vehicle. An acceleration rate is changed in accordance with a frequency with which the host vehicle catches up to a preceding vehicle, which is another vehicle immediately ahead of the host vehicle, and to another vehicle ahead of the preceding vehicle.

Abstract: A control device for an internal combustion engine of a spark-ignition type that injects fuel directly into a combustion chamber including a temperature detector that detects the temperature of the combustion chamber, a load detector that detects the load of the internal combustion engine, and a controller. The controller performs a first control when the temperature of the combustion chamber is lower than or equal to a predetermined temperature and the load of the internal combustion engine is higher than a predetermined load such that the timing of fuel injection is advanced compared with the timing when the load of the internal combustion engine is lower than or equal to the predetermined load.

Abstract: A variable valve mechanism provided on a exhaust side of an internal combustion engine, in which a most advanced state is set as an initial state, operating condition detecting means for detecting operating conditions, variable valve control means for controlling an operation of the variable valve mechanism in accordance with the operating conditions, engine condition determining means for determining whether the internal combustion engine is in a cold state or a warm state, and stop request determining means for determining whether or not a stop request has been issued in relation to the internal combustion engine are provided. When a stop request is issued in the cold state, the internal combustion engine is stopped after returning the variable valve mechanism to the initial state.

Abstract: A head IC adjusts an amplitude level of a read signal of a head and outputs to a read channel having an AGC amplifier, includes an AGC amplifier. The AGC amplifier has a feedback loop control type first amplifier and a feed-forward control type second amplifier. The precision of control with respect to a target value is improved, and an AGC amplifier with fast response can be configured. Further, increases in the AGC pull-in type can be prevented, stability can be assured, and erroneous AGC judgments can be prevented.

Abstract: An internal combustion engine control apparatus is provided with a hydraulically operated variable valve operating mechanism for varying the valve timing of air intake valves, and a water temperature sensor for sensing engine coolant temperature to estimate the degree of engine warm-up. The valve operating mechanism is controlled to switch the valve timing from the warm-up idle valve timing with a high idling speed to the post-warm-up idle valve timing with a slower idling speed as the engine temperature approaches the warm-up temperature threshold. The switch in valve timings starts before an engine rotational speed falls below a rotational speed threshold lying between the high idling speed during the warm-up idling and the post-warm-up idling speed during the post-warm-up idling such that a sufficient hydraulic pressure switch the valve timing with a specific degree of responsiveness is attained when the engine rotational speed is at or above the rotational speed threshold.
