Abstract
A hybrid electronic control unit sets a target vehicle speed for constant-speed driving based on setting operation of an auto cruise switch by a driver. When the target vehicle speed is set, the required torque is set such that the vehicle speed detected by a vehicle speed sensor becomes the target vehicle speed. When the required torque is set, a constant-speed driving torque map, indicating the required torque with respect to a torque command value by accelerator operation or brake operation by the driver using the required torque, and a positive maximum torque and a negative maximum torque, which the vehicle can output, is set. Further, the required torque changes using the constant-speed driving torque map according to the torque command value. In the hybrid electronic control unit, by increasing followability of torque change when changing the vehicle speed from the constant-speed driving, controllability is improved and drivability is improved.
