A lane information detection unit detects the shape and the road width of a traveling lane of a vehicle. A present transverse position detection unit detects a present transverse position indicating a present traveling position of the vehicle in the width direction of the traveling lane. A driver-corresponding transverse position setting unit sets a driver-corresponding transverse position corresponding to a driving tendency of a driver. An upper/lower limit value setting unit sets upper/lower limit values that the driver-corresponding transverse position can take, in accordance with the road width. Then, when change in the road width is detected, a transverse position control amount calculation unit sets, as a target transverse position, the driver-corresponding transverse position within the upper/lower limit values in which the change is reflected, and calculates a transverse position control amount for the vehicle from the present transverse position of the vehicle.

Vehicle control device and vehicle control method

By an offset amount being calculated based on a lateral position deviation from a target travel path at a forward point-of-gaze of a host vehicle at a time of a driver steering state, a series of vehicle control operations until switching back from the driver steering state to an automatic steering control, and traveling along an offset travel path, becomes smoother, whereby comfort when riding in a vehicle is increased.

With respect to a failure in voltage sensors each for detecting a high-voltage-side voltage in a DC/DC converter, it is so arranged that a circuit failure of the DC/DC converter is prevented, and that the DC/DC converter is continuingly controlled. Two voltage sensors are included therein each for detecting a high-voltage-side voltage, so that, even when a first voltage sensor for detecting a high-voltage-side voltage on one side fails to work properly, a control device turns on a second switching device, and detects a voltage by a second voltage sensor for detecting the high-voltage-side voltage on the other side, whereby a failure of the voltage sensor for detecting the high-voltage-side voltage is detected.
