Braking/driving control apparatus for vehicle

A braking/driving control apparatus for a vehicle, the apparatus comprising:

• a basic control unit which calculates and outputs a target axle torque based on a target acceleration set as an acceleration of the vehicle to be achieved and a driving resistance of the vehicle including an effect of gravity according to a gradient of a road, and which determines an axle torque to be required for a power train of the vehicle and an axle torque to be required for a braking apparatus of the vehicle based on the calculated target axle torque;
• a sliding-down prediction determining unit which determines whether there is a possibility that the vehicle slides down rearwards on an uphill road, during deceleration of the vehicle;
• and
• a sliding-down preventing process executing unit which performs a process for reducing a possibility that the vehicle slides down, based on a determination result of the sliding-down prediction determining unit,
• wherein until the sliding-down prediction determining unit determines that there is a possibility that the vehicle slides down rearwards on an uphill road, the sliding-down preventing process executing unit controls the basic control unit to calculate and output the target axle torque so as to reach an estimated value of an axle torque which is necessary for the vehicle to achieve the target acceleration against the driving resistance, and
• wherein after the sliding-down prediction determining unit determines that there is a possibility that the vehicle slides down rearwards on an uphill road, the sliding-down preventing process executing unit controls the basic control unit to calculate and output the target axle torque so as to reach an axle torque which is obtained by reducing a predetermined positive amount form the estimated value of the axle torque necessary for the vehicle to achieve the target acceleration against the driving resistance.
