VEHICLE CONTROL APPARATUS
First Claim
1. A control apparatus of a vehicle in which a by-wire range switching apparatus that performs range switching of an automatic transmission using an actuator is mounted, the control apparatus comprising:
- a coping means that, when a range switching request is identified to be in a specific pattern that reverses the present drive power direction, increases the degree of restriction of drive power transmission compared to a case of a range switching request that is not in that specific pattern.

Abstract
In a control apparatus (3, 40) of a vehicle in which a by-wire range switching apparatus (10) that performs range switching of an automatic transmission 2 using an actuator 60 is mounted, even if a range switching failure occurs in the course of performing range switching in a specific pattern (for example, R→D, or D→R) so as to reverse the present drive power direction, vehicle movement can be suppressed or prevented as much as possible.
The control apparatus (3, 40) includes a coping means (Steps S1 and S5) that, when the request to switch to a forward range or a reverse range has been identified as a request in that specific pattern, reduces the generated output of a drive source 1 to a lower limit side, and an execution means (Steps S2, S4, and S6) that controls the range switching apparatus 10 so as to establish the requested range.

2. A control apparatus of a vehicle in which a by-wire range switching apparatus that performs range switching of an automatic transmission using an actuator is mounted, the control apparatus comprising:
-
a coping means that, when a range switching request is identified to be in a specific pattern that reverses the present drive power direction, decreases output of a drive source mounted in the vehicle to a lower limit side; and an execution means that controls the range switching apparatus so as to establish the requested range. - View Dependent Claims (4)

3. A control apparatus of a vehicle in which a by-wire range switching apparatus that performs range switching of an automatic transmission using an actuator is mounted, and also a hydraulic power transmission adjustment means that adjusts drive power transmission from a drive source to drive wheels is mounted, the control apparatus comprising:
-
a coping means that, when a range switching request is identified to be in a specific pattern that reverses the present drive power direction, decreases output of the drive source to a lower limit side; an execution means that controls the range switching apparatus so as to establish the requested range; a confirmation means that checks whether the executed range switching has been properly completed, or a failure has occurred due to an operation malfunction during the range switching; and a measuring means that, when occurrence of a failure has been detected by the confirmation means, restricts drive power transmission with the power transmission adjustment means. - View Dependent Claims (8)

5. A control apparatus of a vehicle in which a by-wire range switching apparatus that performs range switching of an automatic transmission using an actuator is mounted, and also a hydraulic power transmission adjustment means that adjusts drive power transmission from a drive source to drive wheels is mounted, the control apparatus comprising:
-
a coping means that, when a range switching request is identified to be in a specific pattern that reverses the present drive power direction, restricts drive power transmission by the power transmission adjustment means; and an execution means that controls the range switching apparatus so as to establish the requested range. - View Dependent Claims (6, 7)
