VEHICLE DRIVE CONTROL DEVICE |
摘要 |
A vehicle drive control device in a vehicle including an engine comprising a throttle valve and a supercharger with an air bypass valve changed from a closing side to an opening side when a closing speed of the throttle valve is higher than a speed determination value, the vehicle drive control device providing a torque-down control of the engine by operating the throttle valve to a closing side, wherein at the time of provision of the torque-down control of the engine in which the throttle valve is operated to the closing side when a rotation speed of the engine is equal to or greater than a predetermined rotation speed and a speed ratio of a torque converter is equal to or less than a predetermined value in a supercharged state, the throttle valve is caused to perform a closing operation at the closing speed lower than the speed determination value. |

1. A vehicle drive control device in a vehicle including an engine comprising a throttle valve and a supercharger with an air bypass valve changed from a closing side to an opening side when a closing speed of the throttle valve is higher than a speed determination value, the vehicle drive control device providing a torque-down control of the engine by operating the throttle valve to a closing side, wherein
at the time of provision of the torque-down control of the engine in which the throttle valve is operated to the closing side when a rotation speed of the engine is equal to or greater than a predetermined rotation speed and a speed ratio of a torque converter is equal to or less than a predetermined value in a supercharged state, the throttle valve is caused to perform a closing operation at the closing speed lower than the speed determination value. |
