Title: VEHICLE CONTROL DEVICE
Abstract:
In the prior art, when acceleration control has to be halted due to another vehicle cutting in front or the like, control would be implemented to change the rotation speed of the engine from a high rotation speed to a low rotation speed, causing a significant change in engine rotation speed and worsening drivability for the driver. In addition, when there is a possibility of another vehicle cutting in front, acceleration would be suppressed, which would conversely prompt other vehicles to cut in front, disturbing the driver. The present invention addresses this problem by providing a vehicle control device comprising: a target engine rotation speed calculation unit for correcting a target engine rotation speed so as to become less than a predetermined target engine rotation speed when a possibility of deceleration is determined by an acceleration/deceleration possibility determination unit while acceleration is being performed so as to reach a target vehicle speed during automatic acceleration/deceleration control; and an engine control unit for controlling the engine so as to reach the target engine rotation speed corrected by the target engine rotation speed calculation unit.
