Abstract
A vehicle controller includes a lock-up clutch disposed to a power transmission path between an engine and a driving wheel, and a clutch configured to connect and disconnect the power transmission path, wherein at the time of switching driven traveling for causing a vehicle to travel by connecting the power transmission path and inertia traveling for causing the vehicle to travel by disconnecting the power transmission path, the lock-up clutch and the clutch are switched at switching start timings different from each other.
Claims7
A vehicle controller comprising:
- a lock-up clutch disposed to a power transmission path between an engine and a driving wheel;
- and
- a clutch configured to connect and disconnect the power transmission path, wherein
- a release start timing of the lock-up clutch is prior to a release start timing of the clutch at a time of switching from driven traveling for causing a vehicle to travel by connecting the power transmission path to inertia traveling for causing the vehicle to travel by disconnecting the power transmission path, and an engagement start timing of the clutch is made different from an engagement start timing of the lock-up clutch at a time of switching from the inertia traveling to
- the driven traveling is carried out, wherein the inertia traveling is carried out when an accelerator opening degree of an accelerator pedal is set to a predetermined opening degree or less,
- wherein in the inertia traveling, engine speed is reduced to an idle rotation number.
A vehicle controller comprising:
- a lock-up clutch disposed to a power transmission path between an engine and a driving wheel;
- and
- a clutch configured to connect and disconnect the power transmission path, wherein
- at least any one of that a release start timing of the lock-up clutch is made different from a release start timing of the clutch at a time of switching from driven traveling for causing a vehicle to travel by connecting the power transmission path to inertia traveling for causing the vehicle to travel by disconnecting the power transmission path, and an engagement start timing of the clutch is made different from an engagement start timing of the lock-up clutch at a time of switching from the inertia traveling to the driven traveling is carried out and wherein
- at the time of switching between the driven traveling and the inertia traveling, an auxiliary machine load of the engine is reduced.
