Electronic control apparatus for a vehicle |
摘要 |
An electronic control apparatus for a vehicle, which operates a power conversion circuit connected to a rotating machine used as an in-vehicle traction unit to control controlled variables of the rotating machine, includes a controlling arithmetic processing unit which performs arithmetic processing to control the controlled variables of the rotating machine, and a monitoring arithmetic processing unit which monitors the controlling arithmetic processing unit. The monitoring arithmetic processing unit includes an on-monitoring prohibition unit which prohibits outputting an operation signal from the controlling arithmetic processing unit to the power conversion circuit until the controlling arithmetic processing unit is confirmed to be in a normal condition. |

1. An electronic control apparatus for a vehicle which operates a power conversion circuit connected to a rotating machine used as an in-vehicle traction unit to control controlled variables of the rotating machine, comprising:
a controlling arithmetic processing unit which performs arithmetic processing to control the controlled variables of the rotating machine; and a monitoring arithmetic processing unit which monitors the controlling arithmetic processing unit, and a reset-time prohibition unit which prohibits outputting an operation signal from the controlling arithmetic processing unit to the power conversion circuit between the time when the monitoring arithmetic processing unit is reset and the time when the monitoring arithmetic processing unit is recovered, wherein the monitoring arithmetic processing unit includes an on-monitoring prohibition unit which prohibits outputting the operation signal from the controlling arithmetic processing unit to the power conversion circuit until the controlling arithmetic processing unit is confirmed to be in a normal condition, and when one of the controlling arithmetic processing unit and the monitoring arithmetic processing unit is reset, the other of the controlling arithmetic processing unit and the monitoring arithmetic processing unit is also reset.
