The driving force ECU calculates a restricted driving force for a driving force restricting control, by using a Proportional-Integral-Differential control formula which utilizes a difference between a target acceleration varied depending on a vehicle speed and an actual acceleration of the vehicle. The driving force ECU adjusts (changes) a proportion gain K1 of the Proportional-Integral-Differential control formula based on an inclination angle &#x3b8; of a road in such a manner that a value of the proportion gain K1 used when the inclination inclination angle &#x3b8; is relatively large is smaller than a value of the proportion gain K1 used when the inclination inclination angle &#x3b8; is relatively small. The driving force ECU performs a driving force restricting control by selecting, as a target driving force used for the driving force restricting control, a pedal required driving force or the restricted driving force, whichever is smaller.

Driving force control apparatus for vehicle

A vehicle control device comprises an accelerator () which a driver of a vehicle operates in order to accelerate the vehicle, and a controller configured to execute a limit control for imposing a limitation on a driving force, in such a manner that the driving force is prevented from becoming excessively large, when a predetermined limit condition is satisfied. The controller executes the limit control and a mistaken operation notification, when a mistaken operation state has been occurring. The controller executes a failure notification, when the mistaken operation state has not been occurring at a failure occurrence time point at which a control failure that the controller cannot execute the limit control has occurred. The controller continues executing the mistaken operation notification without executing the failure notification at the failure occurrence time point, if the mistaken operation state has been occurring at the failure occurrence time point.

Vehicle control device for executing a limit control for limiting a driving force of a vehicle

A driving support device executes a limit control to control a vehicle in such a manner that an actual acceleration of when the vehicle is being reversed does not exceed a limit acceleration during a time period from a time point that a start condition becomes satisfied to a time point that an end condition becomes satisfied. The driving support device sets a state of itself to either one of a prohibiting state in which an execution of the limit control is prohibited or an allowing state in which the execution of the limit control is allowed. The driving support device sets the state of itself to the allowing state when a failure that the driving support device cannot detect/receive a request signal occurs.

Driving support device

A controller of a driving force control apparatus starts shift-change-timing restrain control to limit operation driving force at a timing when a starting condition including a condition that a shift position has changed when an accelerator pedal is in an operating state becomes satisfied, and performs reverse-timing restrain control to limit the operation driving force when a performing condition including a condition that the accelerator pedal is in the operating state as well as the shift position is in a reverse position is satisfied. When a specific operation is performed during the shift-change-timing restrain control being performed, the controller moderates a degree of the limitation to the operation driving force in the shift-change-timing restrain control or stops this control. When the specific operation is performed during the reverse-timing restrain control being performed, the controller maintains a degree of the limitation to the operation driving force in the reverse-timing restrain control.

Driving force control apparatus

A vehicle controller applies a braking force to wheels using a hydraulic braking force generating mechanism and sets a vehicle driving torque, which is generated by an engine, to a second torque which is smaller than a first torque in a normal state, when a switch is switched to an ON state in a state in which a vehicle is traveling and an accelerator is turned on. Then vehicle stops, the vehicle controller implements an EPB mechanical operating state using a mechanical parking brake mechanism. When the switch is switched to an OFF state, the vehicle controller maintains the EPB mechanical operating state until an accelerator pedal operating level reaches '0,' and maintains the vehicle driving torque at the second torque. Then the accelerator pedal operating level reaches '0', the EPB mechanical operating state is released and the vehicle driving torque is returned to the first torque.
