摘要： A drive force control apparatus includes a drive force control section that has a steady drive force, a filtered drive force obtained by performing a filtering process on the steady drive force, and an internal drive force, which is calculated from a traction requested drive force, input thereto, and sets a target drive force based on the steady drive force, the filtered drive force, and the internal drive force. The drive force control section implements post-operation processing after control for causing the internal drive force to be the target drive force ends. In the post-operation processing, a new internal drive force, which is calculated based on a large-small relationship among the steady drive force, the filtered drive force, and the previously calculated internal drive force, is set as the target drive force.

摘要： In case a vehicle speed control is performed in response to a failure in a steer-by-wire steering system, the vehicle is prevented from accelerating following a speed reduction caused by a braking operation of the vehicle operator. The speed limit control limits a traveling speed of the vehicle below an upper limit speed upon detecting a fault in the steering system, and is configured to set a target deceleration of the vehicle according to the limited traveling speed, perform a deceleration control to bring an actual deceleration of the vehicle to become near the target deceleration, and restrict the actual deceleration from changing to an acceleration side in the deceleration control.

摘要： Motor-generators are arranged both at front and rear wheels so as to be capable of using all of four wheels for regeneration. The horizontal axis indicates deceleration of a vehicle, and the vertical axis indicates braking forces for the front and rear wheels, respectively above and below the horizontal axis. A setting value indicates a limit braking force for the rear wheels to be locked. A frictional braking force and a regenerative braking force at the rear wheels are controlled so that the total braking force for the rear wheels does not exceed the setting value.

摘要： A vehicle control system for controlling an output of a drive source in a vehicle includes: a drive operation member configured to receive an input regarding a driving force for the vehicle from a driver of the vehicle; and a control device configured to cause the drive source to output a driving force corresponding to the input to the drive operation member. When the control device determines that a predetermined enabling condition is satisfied, the control device enables drive restriction for limiting the output of the drive source. The enabling condition includes an input condition which is based on the input to the drive operation member acquired during a predetermined period before start of the drive source.
