In a host controller included in a vehicle control apparatus, a generator-torque-command generating unit monitors an abnormal operation of the engine on the basis of an engine power generation command and a detection signal of a rotating speed detector, switches, when the abnormal operation of the engine is detected, a generator torque command to the lowest value of a torque command value for abnormal time set in advance as the generator torque command, thereafter, gradually increases the generator torque command, and, after recording, as a torque limit value, the magnitude of the generator torque command (a torque command value for abnormal time 3) at the time when the abnormal operation of the engine is detected again, switches the generator torque command to a torque command value for abnormal time (a torque command value for abnormal time 2) having a value smaller than the torque limit value. |

1. A vehicle control apparatus applied to a vehicle driving system including an engine, an engine controller that controls operation of the engine, a generator coupled to the engine, a converter that converts alternating-current power output by the generator into desired direct-current power, a load apparatus receives supply of the direct-current power from the converter and operate, and a rotating-speed detector that detects rotating speed of the generator, the vehicle control apparatus being configured to be capable of controlling operations of the engine controller and the converter, wherein
a host controller that collectively controls the engine controller and the converter is provided, the host controller includes:
an engine-power-generation-command generating unit that generate an engine power generation command for causing the engine to operate and driving the generator, and outputs the engine power generation command to the engine controller; anda generator-torque-command generating unit that receives notch information in a plurality of stages included in the engine power generation command, select torque corresponding to magnitude of a notch, and output the selected torque to the converter as a generator torque command, wherein the generator-torque-command generating unit monitors an abnormal operation of the engine on the basis of the engine power generation command and a detection signal of the rotating speed detector, switches, when the abnormal operation of the engine is detected, the generator torque command to the lowest value of a torque command value for abnormal time set in advance as the generator torque command, thereafter, gradually increases the generator torque command, and, after recording, as a torque limit value, magnitude of the generator torque command at the time when the abnormal operation of the engine is detected again, switches the generator torque command to a torque command value for abnormal time having a value smaller than the torque limit value. |
