Engine controlling apparatus

摘要

An engine controlling apparatus for executing (i) an engine automatic stop control and/or (ii) an engine automatic restart control, during running of a vehicle. The controlling apparatus includes: an allowing/inhibiting device configured to selectively allow and inhibit execution of (i) the engine automatic stop control and/or (ii) the engine automatic restart control, by comparing each of at least one of (a) a plurality of physical amounts including (a-1) behavior-representing physical amounts and (a-2) turning-behavior-influencing physical amounts, with (b) a threshold value which is determined, depending on a running velocity of the vehicle, for the each of the at least one of the physical amounts. The behavior-representing physical amounts include at least one turning-behavior-representing physical amount. The allowing/inhibiting device includes a turning-behavior-basis allowing/inhibiting portion that is configured to selectively allow and inhibit the execution of (i) the engine automatic stop control and/or (ii) the engine automatic restart control, by comparing each of the at least one turning-behavior-representing physical amount, with the threshold value.

1. An engine controlling apparatus for executing, during running of a vehicle, at least one of (i) an engine automatic stop control for automatically stopping an engine of the vehicle and (ii) an engine automatic restart control for automatically restarting the engine, said engine controlling apparatus comprising:
an input portion to which a yaw rate sensor is connected, said yaw rate sensor being configured to detect a yaw rate of the vehicle; a storage portion storing therein a threshold-value determining table representing a relationship between a running velocity of the vehicle and a threshold value that is determined for the running velocity, the threshold value being determined such that the determined threshold value is smaller when the running velocity is high than when the running velocity of the vehicle is low; and an inhibiting portion that is configured to inhibit the execution of said at least one of (i) the engine automatic stop control and (ii) the engine automatic restart control, when the yaw rate detected by said yaw rate sensor is not smaller than the threshold value.
