Title:
DRIVE SUPPORT DEVICE
Document Type and Number:
Japanese Patent JP2019142293
Kind Code:
A
Abstract:
To provide a drive support device which can accurately detect and prevent an accelerator erroneous operation which is liable to occur when retreating a vehicle while operating a brake or releasing the operation even if a prescribed time has elapsed from a shift position changeover time point.SOLUTION: When an index value which changes according to an accelerator operation amount (AP) being an operation amount of an accelerator operator by a driver satisfies an index value condition within a period in which a shift position is a reverse position (R) for retreating a vehicle, a drive support ECU determines that an accelerator erroneous operation is performed when there is established an accelerator erroneous operation condition which is established when a time from a brake-off time point (t3) at which the brake operator is not operated up to a time point (t4) at which the index value does not satisfy the index value condition is not longer than a prescribed threshold time (T2th). In this case, the drive support ECU sets a drive force generated by a drive unit according to the accelerator operation amount small compared with the case that the accelerator erroneous operation condition is not established.SELECTED DRAWING: Figure 2
