The present invention provides a travel control apparatus for controlling traveling of a self-vehicle to avoid another vehicle on a front side, the apparatus comprising: a calculation unit for calculating a relative speed between the self-vehicle and the other vehicle; a state detection unit for detecting an operation state of the other vehicle; and a control unit for controlling avoidance processing of avoiding the other vehicle and causing the self-vehicle to pass a lateral side of the other vehicle, wherein the control unit changes a separation distance to separate the self-vehicle and the other vehicle in the avoidance processing in accordance with the relative speed calculated by the calculation unit and the operation state detected by the state detection unit.

Travel control apparatus and vehicle

A fuel injection control apparatus for an internal combustion engine having cylinders each of which includes a fuel injection valve and an intake valve, includes an intake valve controller, a parameter acquiring device, and an injection quantity correcting device. The intake valve controller performs an effective-compression-ratio reducing operation. The parameter acquiring device acquires a correction parameter including at least one of a rotational speed of the internal combustion engine, the valve closing timing of the intake valve, and an intake parameter indicating an intake fresh air amount flowing into the cylinders through an intake system. The injection quantity correcting device corrects a fuel injection quantity for the fuel injection valve in accordance with the acquired correction parameter to suppress variations among air/fuel ratios of air fuel mixtures in the cylinders while the intake valve controller performs the effective-compression-ratio reducing operation.

Fuel injection control apparatus

A knocking detector is to detect knocking in the internal combustion engine in which a low-octane fuel is injected into a cylinder and a high-octane fuel whose octane number higher than an octane number of the low-octane fuel is injected into an inlet port. A knocking suppressor includes a first knocking suppressor and a second knocking suppressor. The first knocking suppressor is to increase a high-octane fuel ratio of an injection quantity of the high-octane fuel to a sum of an injection quantity of the low-octane fuel and the injection quantity of the high-octane fuel in order to suppress knocking in the internal combustion engine when the knocking detector detects the knocking. The second knocking suppressor is to suppress knocking of the internal combustion engine at a beginning of a period while the first knocking suppressor increases the high-octane fuel ratio.
