Claim:
1. A vehicle control apparatus provided with an internal combustion engine having an output shaft and a rotary electric machine each functioning as a power source, and operative in states changeable between a stopped state and an operation state of the internal combustion engine while a vehicle is running, comprising: at least one electronic control unit configured to: i) control the rotary electric machine so as to rotate the output shaft of the internal combustion engine with the power of the rotary electric machine in response to an acceleration request to execute a start-up control to have the internal combustion engine transferred from the stopped state to the operation state, ii) set a rise rate of an engine rotational speed of the internal combustion engine after a completion of the start-up control, wherein the at least one electronic control unit is configured to set the rise rate of the engine rotational speed of the internal combustion engine to a higher rise rate in a case that a condition is established with a vehicle speed higher than a predetermined vehicle speed value, and with a value indicative of the acceleration request higher than a predetermined value, which is not zero, as compared with a normal rise rate which is set in a case that the condition is not established with the vehicle speed higher than a predetermined value, and with the value indicative of the acceleration request higher than a predetermined value, which is not zero, and the at least one electronic control unit is configured to set the rise rate of the engine rotation speed of the internal combustion engine after the completion of the start-up control reduced by a predetermined reduction value from an actual rise rate of the engine rotation speed and thereafter set the rise rate of the engine rotation speed of the internal combustion engine to the higher rise rate, in a case that the actual rise rate is increased beyond the higher rise rate by elapse of a predetermined time after the completion of the start-up control.
