  • Patent number: 10583836
    Abstract: Provided is a novel control apparatus for a vehicle which allows the number of stops and restarts to be reduced while performing engine stop and coasting control. The configuration is such that, when there is a high probability of restarting an engine under circumstances where engine stop and coasting control is performed, the engine is maintained in idling operation while only the clutch is disengaged. For example, if it is determined that there is a high probability of restarting due to a change in the acceleration of a host vehicle or a preceding vehicle, the clutch is disengaged and the vehicle is coasted. Since the engine is maintained in an idle state, there is no need for restarting, and the number of restarts can be minimized.

  • Publication number: 20190168732
    Abstract: When acceleration control is interrupted due to a lane change or the like, the engine speed is controlled from a high rotation speed to a low rotation speed, a variation in engine speed increases, and poor driver's driving performance is brought about. Furthermore, suppression of acceleration when there is a lane change possibility may rather cause the lane change and the driver feels discomfort. The vehicle control unit according to the present invention includes a target engine speed calculation unit which corrects a target engine speed to be reduced relative to a predetermined target engine speed when the acceleration/deceleration possibility determination unit determines that there is a deceleration possibility during acceleration to a target vehicle speed in automatic acceleration/deceleration control, and an engine control unit which controls an engine to have a target engine speed corrected by the target engine speed calculation unit.
