<P>PROBLEM TO BE SOLVED: To prove controllability and driveability by increasing the follow-up property of torque change in the case of changing a speed from constant speed traveling in the driving force control device of a vehicle. <P>SOLUTION: An electronic control unit 20 for hybrid sets a target speed Vt for constant speed traveling based on the setting operation of an auto-cruise switch 52 of a driver, and when the target speed Vt is set, sets request torque Trt so that a speed V detected by a speed sensor 51 can be set to the target speed Vt, and when the request torque Trt is set, sets a torque map for constant speed traveling showing the request torque Vrt to a torque command value by the accelerator operation or brake operation of the driver by using the request torque Trt and the positive maximum torque Tramax and negative maximum torque Trbmax which can be output by the vehicle, and controls the change of the request torque Trt by using the torque map for constant speed traveling according to the torque command value. <P>COPYRIGHT: (C)2009,JPO&INPIT |
