Improved is determination accuracy on whether or not a driver is erroneously performing an accelerator operation instead of a brake operation. A pedal opening degree PPO by a driver and a continuation time Te for which the pedal opening degree PPO is greater than an opening degree threshold value Pth are detected. When the continuation time Te exceeds a time threshold value Tth, it is determined that the driver is erroneously performing an accelerator operation instead of a brake operation. A vehicle speed V of a vehicle, a rising gradient Sr of a road surface, and an accelerator operation time Tp operated by the driver are detected. The opening degree threshold value Pth is made variable in accordance with the vehicle speed V, the rising gradient Sr, and the operation time Tp. The time threshold value Tth is made variable in accordance with the vehicle speed V, the rising gradient Sr, and the operation time Tp. |
