Abstract: A main ECU (71) for generating an actual acceleration/deceleration running pattern based on a current running situation of a vehicle, generating a corrected acceleration/deceleration running pattern obtained by elongating an actual acceleration/deceleration period of the actual acceleration/deceleration running pattern when an actual acceleration/deceleration period (T1) in the actual acceleration/deceleration running pattern is shorter than a reference acceleration/deceleration period (T0) set in advance, and setting the actual acceleration/deceleration running pattern as a best acceleration/deceleration running pattern when the corrected acceleration/deceleration running pattern is not generated and setting the corrected acceleration/deceleration running pattern as the best acceleration/deceleration running pattern when the corrected acceleration/deceleration running pattern is generated, is provided.

Abstract: A hybrid electronic control unit controls to set a target vehicle speed Vt for constant-speed driving based on setting operation of an auto cruise switch by a driver, when the target vehicle speed Vt is set, to set required torque Trt such that the vehicle speed V detected by a vehicle speed sensor becomes the target vehicle speed Vt, when the required torque Trt is set, to set a constant-speed driving torque map indicating the required torque Vrt with respect to a torque command value by accelerator operation or brake operation by the driver using the required torque Trt, and a positive maximum torque Tramax and a negative maximum torque Trbmax, which the vehicle can output, and to change the required torque Trt 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.
