Abstract:
1. A torque control apparatus for an internal combustion engine, comprising: a combustion stop means for stopping fuel combustion of the engine when a combustion stop condition is satisfied; a combustion period torque loss computing means for computing a torque loss of the engine in a combustion period, in which the fuel combustion of the engine takes place, wherein the combustion period torque loss computing means computes the torque loss of the engine based on an operational state of the engine in the combustion period; a combustion stop period torque loss computing means for computing a torque loss of the engine in a combustion stop period, in which the fuel combustion of the engine is stopped by the combustion stop means, wherein the combustion stop period torque loss computing means computes the torque loss of the engine in the combustion stop period based on the torque loss of the engine in the combustion period and a state of the combustion stop implemented by the combustion stop means; and a torque control means for controlling a torque generated from the engine based on: in the combustion period, the torque control means uses the torque loss computed by the combustion period torque loss computing means as the selected one of the torque losses; and in the combustion stop period, the torque control means uses the torque loss computed by the combustion stop period torque loss computing means as the selected one of the torque losses.
