Abstract:
1. A vehicle control apparatus applied to a vehicle driving system including an engine, an engine controller that controls an operation of the engine, a generator coupled to the engine, a converter that converts alternating-current power output from the generator into desired direct-current power, a converter controller that controls an operation of the converter, a load device that receives supply of direct-current power from the converter and operates, a rotational speed detector that detects a rotational speed of the generator, and a battery electrically connected to the load device and the generator, the vehicle control apparatus being configured to be capable of controlling start of the engine, wherein a system controller that overall controls the engine controller, the converter controller, and the converter is provided, and when a plurality of command values are provided in multiple stages as the rotational-speed command value, the system controller selects the rotational-speed command values that are greater than zero in order starting from a smallest rotational-speed command value at predetermined time intervals, drives, through the converter controller, the generator with a rotational-speed command value smaller than an idling maintenance rotational speed of the engine so that a first one of the rotational-speed command values is maintained at a constant speed for a first predetermined time interval and is then increased to a second one of the rotational-speed command values after the beginning of a second predetermined time interval, and starts, through the engine controller, fuel injection to the engine after the increase to second one of the rotational-speed command values.
