Engine controlling apparatus
View Patent ↗An engine controlling apparatus includes an idle speed setting unit that sets a target idle speed upon idling of an engine mounted on a vehicle, and a target torque setting unit that sets a target torque in response to the target idle speed. The apparatus further includes an ignition timing controlling unit that controls an ignition timing and an intake air amount controlling unit that controls an intake air amount, and a steering angle detection unit that detects a steering angle. The apparatus further includes a torque value setting unit that sets a torque value in response to the steering angle. The intake air amount controlling unit controls the intake air amount in response to both the target torque and the torque value. The ignition timing controlling unit controls the ignition timing so that the engine outputs the target torque.
1. An engine controlling apparatus, comprising:
an idle speed setting unit that sets a target idle speed upon idling of an engine mounted on a vehicle;
a target torque setting unit that sets a target torque in response to the target idle speed set by said idle speed setting unit;
an ignition timing controlling unit that controls an ignition timing of the engine and an intake air amount controlling unit that controls an intake air amount of the engine so that the target torque set by said target torque setting unit is implemented;
a steering angle detection unit that detects a steering angle of a steering wheel of the vehicle; and
a torque value setting unit that sets a torque value larger as the steering angle detected by said steering angle detection unit increases; wherein
said intake air amount controlling unit increases the intake air amount as sum of the target torque and the torque value increases,
said ignition timing controlling unit retards the ignition timing so that the engine outputs the target torque set by said target torque setting unit,
the control for increasing the intake air amount is carried out simultaneously with retarding of the ignition timing, and
the torque value set by the torque value setting unit is reflected only to the intake air amount but not to the ignition timing.
2. The engine controlling apparatus according to claim 1 , wherein said torque value setting unit increases the torque value in a stepwise manner as an absolute value of the steering angle detected by said steering angle detection unit exceeds threshold values.
