Abstract
A control device for a vehicle including an internal combustion engine and an electric rotary machine connected to the internal combustion engine in a power-transmittable manner is able to perform torque-down through ignition delay control for delaying an ignition timing of the internal combustion engine and regeneration control for performing regeneration using the electric rotary machine when there is a torque-down request based on a vehicle state. The control device is configured to perform torque-down corresponding to a deficiency by delaying the ignition timing of the internal combustion engine when an actual torque of the electric rotary machine through the regeneration control is deficient for the torque-down request.
Claims3
A control device for a vehicle including an internal combustion engine and an electric rotary machine connected to the internal combustion engine in a power-transmittable manner, the control device being able to perform torque-down through ignition delay control for delaying an ignition timing of the internal combustion engine and regeneration control for performing regeneration using the electric rotary machine when there is a torque-down request based on a vehicle state,
- wherein the control device is configured to perform torque-down corresponding to a deficiency by delaying the ignition timing of the internal combustion engine when an actual torque of the electric rotary machine through the regeneration control is deficient for the torque-down request,
- wherein a guard value for slowly changing a regenerative torque output from the electric rotary machine through the regeneration control is set in the regenerative torque, and
- wherein the guard value is a value varying according to a vehicle speed and is set such that a rate of change in regenerative torque per unit time increases as the vehicle speed increases.
