Vehicle control system

摘要

A vehicle control system includes an internal combustion engine capable of switching an operating state and a non-operating state while a vehicle travels, an engaging device capable of switching an engaged state in which the internal combustion engine is engaged with a driving wheel so that a power can be transmitted therebetween and a release state in which the engagement is released, and a controller configured to control the internal combustion engine and the engaging device based on a vehicle speed parameter as to a traveling speed of the vehicle and a determination parameter different from the vehicle speed parameter, place the engaging device in a release state at the time stop permission conditions of the internal combustion engine as to the determination parameter have been established while the vehicle travels at deceleration.

1. A vehicle control system comprising:
an internal combustion engine capable of switching an operating state and a non-operating state thereof while a vehicle travels; an engaging device configured to switch an engaged state in which the internal combustion engine is engaged with a driving wheel so that a power can be transmitted therebetween and a release state in which the engagement is released; and a controller configured to control the internal combustion engine and the engaging device based on a vehicle speed parameter as to a traveling speed of the vehicle and a determination parameter different from the vehicle speed parameter, while the vehicle travels at deceleration, place the engaging device in the release state at the time stop permission conditions of the internal combustion engine as to the determination parameter have been established and before an internal combustion engine stop request is generated, and place the internal combustion engine in a non-operating state at the time the stop permission conditions of the internal combustion engine as to the vehicle speed parameter have been established and the internal combustion engine stop request has been generated wherein the engaging device can engage a rotating member on an internal combustion engine side and a rotating member on a driving wheel side so that a power can be transmitted therebetween and can adjust an engaging force for engaging the rotating member on the internal combustion engine side and the rotating member on the driving wheel side; and the controller changes the engaging force at the time the engaging device is released based on a deviation between an actual difference rotation speed between the rotating member on the internal combustion engine side and the rotating member on the driving wheel side at the time the internal combustion engine stop permission conditions as to the vehicle speed parameter have been established, and a determination difference rotation speed for determining that the engaging device is in the release state.
