PROBLEM TO BE SOLVED: To obtain the same sense of acceleration as that to be perceived during normal driving by shortening a turbo lag of an engine with a supercharger occurring during cruise-controlled run.SOLUTION: A required torque calculation part 25c obtains a required torque Td on the basis of a target driving force Ft which is set in order to attain a target acceleration αt during cruise-controlled run, and a vehicle speed V. An instruction torque calculation part 25d references an engine instruction torque map on the basis of the required torque Td and a boost pressure of a turbo supercharger 5, and obtains an engine instruction torque TE/G for setting an instruction throttle angle THd. The engine instruction torque TE/G stored in the engine instruction torque map is set to a value nearly identical to the required torque Td, however the engine instruction torque TE/G in a domain in which a turbo lag is outstandingly manifested is set to a value higher than the required torque Td. As a result, the same sense of acceleration as that to be perceived during normal driving can be obtained during cruise-controlled run. |
