<p>PURPOSE:To perform adequate slip control by changing valve lift characteristics of at least one of a suction valve and an exhaust valve, and changing the gain of a feedback control quantity calculating means when driving wheels are at the excessive slip state. CONSTITUTION:When an electronic control unit 20 detects the excessive slip state of driving wheels based on signals from a driving wheel speed sensor 21 and a driven wheel speed sensor 22, an ENG-ECU 5 performs the valve timing switching control, i.e., the change control of valve lift characteristics, of the suction valve and the exhaust valve of an engine 1 via a solenoid valve 26. The lean correction coefficient for the basic fuel injection quantity calculated based on signals from an engine rotation sensor 10, a suction pressure sensor 7, and a throttle sensor 4 is set to a value smaller than the value 1.0 at the time of ordinary running. The adequate slip control in response to the change of the delay of a control system can be performed.</p> |
