| 20090088923 | VEHICULAR CONTROL APPARATUS AND PROGRAM STORAGE MEDIUM - Whether an anomaly occurs in a data-rewritable second nonvolatile memory is determined by comparison between (i) a diagnosis code stored in the second nonvolatile memory and (ii) data contents stored as a diagnosis table in a first nonvolatile memory. The first nonvolatile memory previously stores the diagnosis table for listing diagnosis codes. If the diagnosis codes are appropriately registered in the diagnosis table, it is thereafter unnecessary to take into consideration whether the diagnosis codes are normally stored in the first nonvolatile memory. This configuration requires no further rewriting of information in the first nonvolatile memory unlike other memories, and thus decreases a possibility of an occurrence of an anomaly to garble the information in the first nonvolatile memory in comparison with other memories. Whether an anomaly occurs in the second nonvolatile memory can be thus performed more appropriately. | 04-02-2009 |
| 20090157251 | Diagnostic system for automatic transmission - A diagnostic system for an automatic transmission is provided in which a microcomputer determines that torque that can drive the driving wheels of the vehicle is not transmitted to an output shaft of the automatic transmission when the vehicle is stopped and the ignition key is operated to the OFF position, and performs forced energization of solenoids of solenoid valves associated with respective friction devices of the transmission, while monitoring current passing through the solenoid valves. If the current monitored does not match the current for energizing any of the solenoids, the microcomputer determines that the corresponding solenoid valve is at fault. Thus, the diagnostic system appropriately determines the presence of a fault of each solenoid valve for controlling the hydraulic pressure to each friction device, with increased flexibility and freedom. | 06-18-2009 |

| 20100179719 | VEHICLE DRIVING ASSIST SYSTEM - A vehicle driving assist system calculates a risk potential indicative of a degree of convergence between a host vehicle and a preceding obstacle. Then, the system performs a driver notification operation that produces a driver notification stimulus based on the risk potential such as decreasing the driving force exerted against the vehicle as the risk potential increases and increasing an actuation reaction force exerted on the accelerator pedal during its operation as the risk potential increases. If a failure is detected in a reaction force generating device serving to add a reaction force to the accelerator pedal in accordance with the risk potential, then the system corrects an engine torque characteristic such that the engine torque does not increase even if the accelerator pedal is depressed to suppress an odd feeling in the vehicle performance by the driver when a failure occurs in the reaction force generating device. | 07-15-2010 |
