Abstract:
1. A vehicle control apparatus for a vehicle provided with a power source, an accelerator pedal, and a brake pedal, the vehicle control apparatus comprising: an accelerator detection unit that detects a depression of the accelerator pedal; a brake detection unit that detects a depression of the brake pedal; a transfer unit that distributes torque transmitted to wheels of the vehicle, a permission condition determination unit that determines that a control permission condition is established when the depression of the accelerator pedal is detected by the accelerator detection unit, and the depression of the brake pedal is detected by the brake detection unit; an output control unit that executes a reduction control to reduce a driving force to be outputted by the power source when the control permission condition established is determined by the permission condition determination unit; and a bad road travel determination unit that determines the vehicle is travelling on a bad road when an input and output rotation speed ratio of the transfer unit is larger than or equal to a predetermined ratio, and the bad road travel determination unit determines that the vehicle is not travelling on a bad road when the input and output rotation speed ratio is less than the predetermined ratio, and wherein the permission condition determination unit is operative to determine that the control permission condition is not established, and to prohibit the output reduction unit from executing the reduction control when the bad road travel determination unit determines that the vehicle is travelling on a bad road, wherein the output control unit is operative to execute the reduction control when the control permission condition established for no less than a predetermined time is determined by the permission condition determination unit, and wherein the input and output rotation speed ratio of the transfer unit is the ratio of the input rotation speed of the transfer unit detected by a transfer input rotation speed sensor to the output rotation speed of the transfer unit detected by the transfer output rotation speed sensor.
